ASP.NET程序中常用的三十三种代码

2007-01-07 00:54 295 查看
1. 打开新的窗口并传送参数:

  传送参数:

response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>")

  接收参数:

string a = Request.QueryString("id");
string b = Request.QueryString("id1");

  2.为按钮添加对话框

Button1.Attributes.Add("onclick","return confirm(’确认?’)");
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}")

  3.删除表格选定记录

int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex];
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString()

  4.删除表格记录警告

private void DataGrid_ItemCreated(Object sender,DataGridItemEventArgs e)
{
 switch(e.Item.ItemType)
 {
  case ListItemType.Item :
  case ListItemType.AlternatingItem :
  case ListItemType.EditItem:
   TableCell myTableCell;
   myTableCell = e.Item.Cells[14];
   LinkButton myDeleteButton ;
   myDeleteButton = (LinkButton)myTableCell.Controls[0];
   myDeleteButton.Attributes.Add("onclick","return confirm(’您是否确定要删除这条信息’);");
   break;
  default:
   break;
 }

}

  5.点击表格行链接另一页

private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
 //点击表格打开
 if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
  e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);");
}

  双击表格连接到另一页

  在itemDataBind事件中

if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
 string OrderItemID =e.item.cells[1].Text;
 ...
 e.item.Attributes.Add("ondblclick", "location.href=’../ShippedGrid.aspx?id=" + OrderItemID + "’");
}

  双击表格打开新一页

if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
 string OrderItemID =e.item.cells[1].Text;
 ...
 e.item.Attributes.Add("ondblclick", "open(’../ShippedGrid.aspx?id=" + OrderItemID + "’)");
}

6.表格超连接列传递参数

<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’
 <%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ />

  7.表格点击改变颜色

if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem)
{
 e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’;
    this.style.color=’buttontext’;this.style.cursor=’default’;");
}

  写在DataGrid的_ItemDataBound里

if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem)
{
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’;
   this.style.color=’buttontext’;this.style.cursor=’default’;");
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;");
}

  8.关于日期格式

  日期格式设定

DataFormatString="{0:yyyy-MM-dd}"

  我觉得应该在itembound事件中

e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd"))

  9.获取错误信息并到指定页面

  不要使用Response.Redirect,而应该使用Server.Transfer

  e.g

// in global.asax
protected void Application_Error(Object sender, EventArgs e) {
if (Server.GetLastError() is HttpUnhandledException)
Server.Transfer("MyErrorPage.aspx");

//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :)
}

  Redirect会导致post-back的产生从而丢失了错误信息,所以页面导向应该直接在服务器端执行,这样就可以在错误处理页面得到出错信息并进行相应的处理

  10.清空Cookie

Cookie.Expires=[DateTime];
Response.Cookies("UserName").Expires = 0

  11.自定义异常处理

//自定义异常处理类
using System;
using System.Diagnostics;

namespace MyAppException
{
 /// <summary>
 /// 从系统异常类ApplicationException继承的应用程序异常处理类。
 /// 自动将异常内容记录到Windows NT/2000的应用程序日志
 /// </summary>
 public class AppException:System.ApplicationException
 {
  public AppException()
  {
   if (ApplicationConfiguration.EventLogEnabled)LogEvent("出现一个未知错误。");
  }

 public AppException(string message)
 {
  LogEvent(message);
 }

 public AppException(string message,Exception innerException)
 {
  LogEvent(message);
  if (innerException != null)
  {
   LogEvent(innerException.Message);
  }
 }

 //日志记录类
 using System;
 using System.Configuration;
 using System.Diagnostics;
 using System.IO;
 using System.Text;
 using System.Threading;

 namespace MyEventLog
 {
  /// <summary>
  /// 事件日志记录类,提供事件日志记录支持
  /// <remarks>
  /// 定义了4个日志记录方法 (error, warning, info, trace)
  /// </remarks>
  /// </summary>
  public class ApplicationLog
  {
   /// <summary>
   /// 将错误信息记录到Win2000/NT事件日志中
   /// <param name="message">需要记录的文本信息</param>
   /// </summary>
   public static void WriteError(String message)
   {
    WriteLog(TraceLevel.Error, message);
   }

   /// <summary>
   /// 将警告信息记录到Win2000/NT事件日志中
   /// <param name="message">需要记录的文本信息</param>
   /// </summary>
   public static void WriteWarning(String message)
   {
    WriteLog(TraceLevel.Warning, message);  
   }

   /// <summary>
   /// 将提示信息记录到Win2000/NT事件日志中
   /// <param name="message">需要记录的文本信息</param>
   /// </summary>
   public static void WriteInfo(String message)
   {
    WriteLog(TraceLevel.Info, message);
   }
   /// <summary>
   /// 将跟踪信息记录到Win2000/NT事件日志中
   /// <param name="message">需要记录的文本信息</param>
   /// </summary>
   public static void WriteTrace(String message)
   {
    WriteLog(TraceLevel.Verbose, message);
   }

   /// <summary>
   /// 格式化记录到事件日志的文本信息格式
   /// <param name="ex">需要格式化的异常对象</param>
   /// <param name="catchInfo">异常信息标题字符串.</param>
   /// <retvalue>
   /// <para>格式后的异常信息字符串,包括异常内容和跟踪堆栈.</para>
   /// </retvalue>
   /// </summary>
   public static String FormatException(Exception ex, String catchInfo)
   {
    StringBuilder strBuilder = new StringBuilder();
    if (catchInfo != String.Empty)
    {
     strBuilder.Append(catchInfo).Append("\r\n");
    }
    strBuilder.Append(ex.Message).Append("\r\n").Append(ex.StackTrace);
    return strBuilder.ToString();
   }

   /// <summary>
   /// 实际事件日志写入方法
   /// <param name="level">要记录信息的级别(error,warning,info,trace).</param>
   /// <param name="messageText">要记录的文本.</param>
   /// </summary>
   private static void WriteLog(TraceLevel level, String messageText)
   {
    try
    {
     EventLogEntryType LogEntryType;
     switch (level)
     {
      case TraceLevel.Error:
       LogEntryType = EventLogEntryType.Error;
       break;
      case TraceLevel.Warning:
       LogEntryType = EventLogEntryType.Warning;
       break;
      case TraceLevel.Info:
       LogEntryType = EventLogEntryType.Information;
       break;
      case TraceLevel.Verbose:
       LogEntryType = EventLogEntryType.SuccessAudit;
       break;
      default:
       LogEntryType = EventLogEntryType.SuccessAudit;
       break;
     }

     EventLog eventLog = new EventLog("Application", ApplicationConfiguration.EventLogMachineName, ApplicationConfiguration.EventLogSourceName );
     //写入事件日志
     eventLog.WriteEntry(messageText, LogEntryType);

    }
   catch {} //忽略任何异常
  }
 = //class ApplicationLog


12.Panel 横向滚动,纵向自动扩展

<asp:panel style="overflow-x:scroll;overflow-y:auto;"></asp:panel>

  13.回车转换成Tab

<script language="javascript" for="document" event="onkeydown">
 if(event.keyCode==13 && event.srcElement.type!=’button’ && event.srcElement.type!=’submit’ &&     event.srcElement.type!=’reset’ && event.srcElement.type!=’’&& event.srcElement.type!=’textarea’);
   event.keyCode=9;
</script>

onkeydown="if(event.keyCode==13) event.keyCode=9"

  14.DataGrid超级连接列

DataNavigateUrlField="字段名" DataNavigateUrlFormatString="http://xx/inc/delete.aspx?ID={0}"

  15.DataGrid行随鼠标变色

private void DGzf_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
 if (e.Item.ItemType!=ListItemType.Header)
 {
  e.Item.Attributes.Add( "onmouseout","this.style.backgroundColor=\""+e.Item.Style["BACKGROUND-COLOR"]+"\"");
  e.Item.Attributes.Add( "onmouseover","this.style.backgroundColor=\""+ "#EFF3F7"+"\"");
 }
}

  16.模板列

<ASP:TEMPLATECOLUMN visible="False" sortexpression="demo" headertext="ID">
<ITEMTEMPLATE>
<ASP:LABEL text=’<%# DataBinder.Eval(Container.DataItem, "ArticleID")%>’ runat="server" width="80%" id="lblColumn" />
</ITEMTEMPLATE>
</ASP:TEMPLATECOLUMN>

<ASP:TEMPLATECOLUMN headertext="选中">
<HEADERSTYLE wrap="False" horizontalalign="Center"></HEADERSTYLE>
<ITEMTEMPLATE>
<ASP:CHECKBOX id="chkExport" runat="server" />
</ITEMTEMPLATE>
<EDITITEMTEMPLATE>
<ASP:CHECKBOX id="chkExportON" runat="server" enabled="true" />
</EDITITEMTEMPLATE>
</ASP:TEMPLATECOLUMN>

  后台代码

protected void CheckAll_CheckedChanged(object sender, System.EventArgs e)
{
 //改变列的选定,实现全选或全不选。
 CheckBox chkExport ;
 if( CheckAll.Checked)
 {
  foreach(DataGridItem oDataGridItem in MyDataGrid.Items)
  {
   chkExport = (CheckBox)oDataGridItem.FindControl("chkExport");
   chkExport.Checked = true;
  }
 }
 else
 {
  foreach(DataGridItem oDataGridItem in MyDataGrid.Items)
  {
   chkExport = (CheckBox)oDataGridItem.FindControl("chkExport");
   chkExport.Checked = false;
  }
 }
}

  17.数字格式化

  【<%#Container.DataItem("price")%>的结果是500.0000,怎样格式化为500.00?】

<%#Container.DataItem("price","{0:¥#,##0.00}")%>

int i=123456;
string s=i.ToString("###,###.00");

18.日期格式化

  【aspx页面内:<%# DataBinder.Eval(Container.DataItem,"Company_Ureg_Date")%>

  显示为: 2004-8-11 19:44:28

  我只想要:2004-8-11 】

<%# DataBinder.Eval(Container.DataItem,"Company_Ureg_Date","{0:yyyy-M-d}")%>

  应该如何改?

  【格式化日期】

  取出来,一般是object((DateTime)objectFromDB).ToString("yyyy-MM-dd");

  【日期的验证表达式】

  A.以下正确的输入格式: [2004-2-29], [2004-02-29 10:29:39 pm], [2004/12/31]

^((\d{2}(([02468][048])|([13579][26]))[\-\/\s]?((((0?[13578])|(1[02]))[\-\/\s]?((0?[1-9])|([1-2][0-9])|(3[01])))|(((0?[469])|(11))[\-\/\s]?((0?[1-9])|([1-2][0-9])|(30)))|(0?2[\-\/\s]?((0?[1-9])|([1-2][0-9])))))|(\d{2}(([02468][1235679])|([13579][01345789]))[\-\/\s]?((((0?[13578])|(1[02]))[\-\/\s]?((0?[1-9])|([1-2][0-9])|(3[01])))|(((0?[469])|(11))[\-\/\s]?((0?[1-9])|([1-2][0-9])|(30)))|(0?2[\-\/\s]?((0?[1-9])|(1[0-9])|(2[0-8]))))))(\s(((0?[1-9])|(1[0-2]))\:([0-5][0-9])((\s)|(\:([0-5][0-9])\s))([AM|PM|am|pm]{2,2})))?$

  B.以下正确的输入格式:[0001-12-31], [9999 09 30], [2002/03/03]

^\d{4}[\-\/\s]?((((0[13578])|(1[02]))[\-\/\s]?(([0-2][0-9])|(3[01])))|(((0[469])|(11))[\-\/\s]?(([0-2][0-9])|(30)))|(02[\-\/\s]?[0-2][0-9]))$

  【大小写转换】

HttpUtility.HtmlEncode(string);
HttpUtility.HtmlDecode(string)

  19.如何设定全局变量

  Global.asax中

  Application_Start()事件中

  添加Application[属性名] = xxx;

  就是你的全局变量

  20.怎样作到HyperLinkColumn生成的连接后,点击连接,打开新窗口?

  HyperLinkColumn有个属性Target,将器值设置成"_blank"即可.(Target="_blank")

  【ASPNETMENU】点击菜单项弹出新窗口

  在你的menuData.xml文件的菜单项中加入URLTarget="_blank",如:

<?xml version="1.0" encoding="GB2312"?>
<MenuData ImagesBaseURL="images/">
<MenuGroup>
<MenuItem Label="内参信息" URL="Infomation.aspx" >
<MenuGroup ID="BBC">
<MenuItem Label="公告信息" URL="Infomation.aspx" URLTarget="_blank" LeftIcon="file.gif"/>
<MenuItem Label="编制信息简报" URL="NewInfo.aspx" LeftIcon="file.gif" />
......

  最好将你的aspnetmenu升级到1.2版

  21.读取DataGrid控件TextBox值

foreach(DataGrid dgi in yourDataGrid.Items)
{
 TextBox tb = (TextBox)dgi.FindControl("yourTextBoxId");
 tb.Text....
}

  23.在DataGrid中有3个模板列包含Textbox分别为 DG_ShuLiang (数量) DG_DanJian(单价) DG_JinE(金额)分别在5.6.7列,要求在录入数量及单价的时候自动算出金额即:数量*单价=金额还要求录入时限制为数值型.我如何用客户端脚本实现这个功能?

  〖思归〗

<asp:TemplateColumn HeaderText="数量">
<ItemTemplate>
<asp:TextBox id="ShuLiang" runat=’server’ Text=’<%# DataBinder.Eval(Container.DataItem,"DG_ShuLiang")%>’
onkeyup="javascript:DoCal()"
/>

<asp:RegularExpressionValidator id="revS" runat="server" ControlToValidate="ShuLiang" ErrorMessage="must be integer" ValidationExpression="^\d+$" />
</ItemTemplate>
</asp:TemplateColumn>

<asp:TemplateColumn HeaderText="单价">
<ItemTemplate>
<asp:TextBox id="DanJian" runat=’server’ Text=’<%# DataBinder.Eval(Container.DataItem,"DG_DanJian")%>’
onkeyup="javascript:DoCal()"
/>

<asp:RegularExpressionValidator id="revS2" runat="server" ControlToValidate="DanJian" ErrorMessage="must be numeric" ValidationExpression="^\d+(\.\d*)?$" />

</ItemTemplate>
</asp:TemplateColumn>

<asp:TemplateColumn HeaderText="金额">
<ItemTemplate>
<asp:TextBox id="JinE" runat=’server’ Text=’<%# DataBinder.Eval(Container.DataItem,"DG_JinE")%>’ />
</ItemTemplate>
</asp:TemplateColumn><script language="javascript">
function DoCal()
{
 var e = event.srcElement;
 var row = e.parentNode.parentNode;
 var txts = row.all.tags("INPUT");
 if (!txts.length || txts.length < 3)
  return;

 var q = txts[txts.length-3].value;
 var p = txts[txts.length-2].value;

 if (isNaN(q) || isNaN(p))
  return;

 q = parseInt(q);
 p = parseFloat(p);

 txts[txts.length-1].value = (q * p).toFixed(2);
}
</script>

24.datagrid选定比较底下的行时,为什么总是刷新一下,然后就滚动到了最上面,刚才选定的行因屏幕的关系就看不到了。

page_load
page.smartNavigation=true

  25.在Datagrid中修改数据,当点击编辑键时,数据出现在文本框中,怎么控制文本框的大小 ?

private void DataGrid1_ItemDataBound(obj sender,DataGridItemEventArgs e)
{
 for(int i=0;i<e.Item.Cells.Count-1;i++)
  if(e.Item.ItemType==ListItemType.EditType)
  {
   e.Item.Cells[i].Attributes.Add("Width", "80px")
  }
}

  26.对话框

private static string ScriptBegin = "<script language=\"JavaScript\">";
private static string ScriptEnd = "</script>";

public static void ConfirmMessageBox(string PageTarget,string Content)
{
 string ConfirmContent="var retValue=window.confirm(’"+Content+"’);"+"if(retValue){window.location=’"+PageTarget+"’;}";

 ConfirmContent=ScriptBegin + ConfirmContent + ScriptEnd;

 Page ParameterPage = (Page)System.Web.HttpContext.Current.Handler;
 ParameterPage.RegisterStartupScript("confirm",ConfirmContent);
 //Response.Write(strScript);
}

  27. 将时间格式化:string aa=DateTime.Now.ToString("yyyy年MM月dd日");

  1.1 取当前年月日时分秒

currentTime=System.DateTime.Now;

  1.2 取当前年

int 年= DateTime.Now.Year;

  1.3 取当前月

int 月= DateTime.Now.Month;

  1.4 取当前日

int 日= DateTime.Now.Day;

  1.5 取当前时

int 时= DateTime.Now.Hour;

  1.6 取当前分

int 分= DateTime.Now.Minute;

  1.7 取当前秒

int 秒= DateTime.Now.Second;

  1.8 取当前毫秒

int 毫秒= DateTime.Now.Millisecond;

  28.自定义分页代码:

  先定义变量:

public static int pageCount; //总页面数
public static int curPageIndex=1; //当前页面

  下一页:

if(DataGrid1.CurrentPageIndex < (DataGrid1.PageCount - 1))
{
 DataGrid1.CurrentPageIndex += 1;
 curPageIndex+=1;
}

bind(); // DataGrid1数据绑定函数

  上一页:

if(DataGrid1.CurrentPageIndex >0)
{
 DataGrid1.CurrentPageIndex += 1;
 curPageIndex-=1;
}

bind(); // DataGrid1数据绑定函数

  直接页面跳转:

int a=int.Parse(JumpPage.Value.Trim());//JumpPage.Value.Trim()为跳转值

if(a<DataGrid1.PageCount)
{
 this.DataGrid1.CurrentPageIndex=a;
}

bind();

29.DataGrid使用:

  添加删除确认:

private void DataGrid1_ItemCreated(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
 foreach(DataGridItem di in this.DataGrid1.Items)
 {
  if(di.ItemType==ListItemType.Item||di.ItemType==ListItemType.AlternatingItem)
  {
   ((LinkButton)di.Cells[8].Controls[0]).Attributes.Add("onclick","return confirm(’确认删除此项吗?’);");
  }
 }
}

  样式交替:

ListItemType itemType = e.Item.ItemType;

if (itemType == ListItemType.Item )
{
 e.Item.Attributes["onmouseout"] = "javascript:this.style.backgroundColor=’#FFFFFF’;";
 e.Item.Attributes["onmouseover"] = "javascript:this.style.backgroundColor=’#d9ece1’;cursor=’hand’;" ;
}
else if( itemType == ListItemType.AlternatingItem)
{
 e.Item.Attributes["onmouseout"] = "javascript:this.style.backgroundColor=’#a0d7c4’;";
 e.Item.Attributes["onmouseover"] = "javascript:this.style.backgroundColor=’#d9ece1’;cursor=’hand’;" ;
}

  添加一个编号列:

DataTable dt= c.ExecuteRtnTableForAccess(sqltxt); //执行sql返回的DataTable
DataColumn dc=dt.Columns.Add("number",System.Type.GetType("System.String"));

for(int i=0;i<dt.Rows.Count;i++)
{
 dt.Rows[i]["number"]=(i+1).ToString();
}

DataGrid1.DataSource=dt;
DataGrid1.DataBind();

  DataGrid1中添加一个CheckBox,页面中添加一个全选框

private void CheckBox2_CheckedChanged(object sender, System.EventArgs e)
{
 foreach(DataGridItem thisitem in DataGrid1.Items)
 {
  ((CheckBox)thisitem.Cells[0].Controls[1]).Checked=CheckBox2.Checked;
 }
}

  将当前页面中DataGrid1显示的数据全部删除

foreach(DataGridItem thisitem in DataGrid1.Items)
{
 if(((CheckBox)thisitem.Cells[0].Controls[1]).Checked)
 {
  string strloginid= DataGrid1.DataKeys[thisitem.ItemIndex].ToString();
  Del (strloginid); //删除函数
 }
}

  30.当文件在不同目录下,需要获取数据库连接字符串(如果连接字符串放在Web.config,然后在Global.asax中初始化)

  在Application_Start中添加以下代码:

Application["ConnStr"]=this.Context.Request.PhysicalApplicationPath+ConfigurationSettings.
   AppSettings["ConnStr"].ToString();

  31.变量.ToString()

  字符型转换转为字符串

12345.ToString("n"); //生成 12,345.00
12345.ToString("C"); //生成¥12,345.00
12345.ToString("e"); //生成 1.234500e+004
12345.ToString("f4"); //生成 12345.0000
12345.ToString("x"); //生成 3039 (16进制)
12345.ToString("p"); //生成 1,234,500.00%

  32、变量.Substring(参数1,参数2);

  截取字串的一部分,参数1为左起始位数,参数2为截取几位。如:string s1 = str.Substring(0,2);

  33.在自己的网站上登陆其他网站:(如果你的页面是通过嵌套方式的话,因为一个页面只能有一个FORM,这时可以导向另外一个页面再提交登陆信息)

<SCRIPT language="javascript">
<!--
 function gook(pws)
 {
  frm.submit();
 }
//-->

</SCRIPT><body leftMargin="0" topMargin="0" onload="javascript:gook()" marginwidth="0" marginheight="0">
<form name="frm" action=" http://220.194.55.68:6080/login.php?retid=7259 " method="post">
<tr>
<td>
<input id="f_user" type="hidden" size="1" name="f_user" runat="server">
<input id="f_domain" type="hidden" size="1" name="f_domain" runat="server">
<input class="box" id="f_pass" type="hidden" size="1" name="pwshow" runat="server">

<INPUT id="lng" type="hidden" maxLength="20" size="1" value="5" name="lng">
<INPUT id="tem" type="hidden" size="1" value="2" name="tem">

</td>

</tr>

</form>

  文本框的名称必须是你要登陆的网页上的名称,如果源码不行可以用vsniffer 看看。

  下面是获取用户输入的登陆信息的代码:

string name;
name=Request.QueryString["EmailName"];

try
{
 int a=name.IndexOf("@",0,name.Length);
 f_user.Value=name.Substring(0,a);
 f_domain.Value=name.Substring(a+1,name.Length-(a+1));
 f_pass.Value=Request.QueryString["Psw"];
}

catch
{
 Script.Alert("错误的邮箱!");
 Server.Transfer("index.aspx");
}

一个在时间选择上很有用的代码

最近公司在做一个系统,要用一个时间选择控件,本来是用ASP。NET来做,但最后我就用JS来写

具体代码(部分):
TIME.JS
--------------------------------------

//请大家保证版本的完整性
function fTime(iHour,iSec,iMin)
{
return iHour+iSec+iMin;
}
//当前日期
//<input type="text" size="10" name="datBegin" value="<%=formatdatetime(dateandtime_start,2)%>" maxlength="10" readonly onclick="fPopCalendar(datBegin,datBegin);return false">日<%h_time(int(hour(dateandtime_start))),23,"datHourBegin"%>时<%h_time(int(minute(dateandtime_start))),59,"datMinuteBegin"%>分(日期格式:yyyy-mm-dd)
function getNowDate()
{
var nn=new Date();
year1=nn.getYear();
mon1=nn.getMonth()+1;
date1=nn.getDate();
var monstr1;
var datestr1
if(mon1<10)
monstr1="0"+mon1;
else
monstr1=""+mon1;

if(date1<10)
datestr1="0"+date1;
else
datestr1=""+date1;
return year1+"-"+monstr1+"-"+datestr1;
}
//目标日期
function getlastweekDate()
{
var nn=new Date();
year1=nn.getYear();
mon1=nn.getMonth()+1;
date1=nn.getDate();

var mm=new Date(year1,mon1-1,date1);
var tmp1=new Date(2000,1,1);
var tmp2=new Date(2000,1,15);
var ne=tmp2-tmp1;
var mm2=new Date();
mm2.setTime(mm.getTime()-ne);

year2=mm2.getYear();
mon2=mm2.getMonth()+1;
date2=mm2.getDate();

if(mon2<10)
monstr2="0"+mon2;
else
monstr2=""+mon2;

if(date2<10)
datestr2="0"+date2;
else
datestr2=""+date2;

return year2+"-"+monstr2+"-"+datestr2;
}

var gdCtrl = new Object();
var goSelectTag = new Array();
var gcGray = "#808080";
var gcToggle = "#FB8664";
var gcBG = "#e5e6ec";
var previousObject = null;

var gdCurDate = new Date();
var giYear = gdCurDate.getFullYear();
var giMonth = gdCurDate.getMonth()+1;
var giDay = gdCurDate.getDate();
function fSetToday() //直接获取现在的时间
{

}

function fSetDate(iYear, iMonth, iDay){

VicPopCal.style.visibility = "hidden";
if ((iYear == 0) && (iMonth == 0) && (iDay == 0)){
