asp.net常用的javascript经典例子 Dropdownlist无刷新的例子。xml. 例如文本验证! 下面是一个单选按纽前台不刷新的例子.有好的就往上贴 <script language="javascript"> function SetButton() { if(document.all.rdoByHuman.checked==true) { document.all.cboHrPut.disabled = ""; document.all.cboAnswerHr.disabled = ""; document.all.cboGroup.disabled = true; } if(document.all.rdoByGroup.checked==true) { document.all.cboHrPut.disabled = true; document.all.cboAnswerHr.disabled = true; document.all.cboGroup.disabled = ""; } } </script>

<asp:RadioButton id="rdoByHuman" onclick="SetButton();" runat="server" GroupName="TotalGroup" Checked="True" Text="按人员"></asp:RadioButton> e.Item.Attributes.Add("onmouseOver","this.style.backgroundColor='#dee3e7'");//鼠标移上去的颜色 e.Item.Attributes.Add("onmouseOut","this.style.backgroundColor='white'"); e.Item.Cells[2].Attributes.Add("onmouseOver","this.style.backgroundColor='red'"); e.Item.Cells[2].Attributes.Add("onmouseOut","this.style.backgroundColor='white'");//指定某列的颜色 e.Item.Cells[3].Style["cursor"]="hand"; e.Item.Cells[4].Attributes.Add("onclick","alert('你惦记的ID 是:"+e.Item.Cells[4].Text+"');");//指定显示字段 e.Item.Cells[1].Attributes.Add("title","'红孩是未解决的,蓝精灵是已解决的!'"+e.Item.Cells[0].Text.ToString());//显示title e.Item.Cells[0].Attributes.Add("onclick","window.open('xinxiForm.aspx?idmain="+e.Item.Cells[0].Text+"','','ToolBar=no,width=260,height=200');");

屏闭一些键:

function KeyDown(){ //屏蔽鼠标右键、Ctrl+n、shift+F10、F5刷新、退格键 //alert("ASCII代码是:"+event.keyCode); if ((window.event.altKey)&& ((window.event.keyCode==37)|| //屏蔽 Alt+ 方向键 ← (window.event.keyCode==39))){ //屏蔽 Alt+ 方向键 → alert("不准你使用ALT+方向键前进或后退网页!"); event.returnValue=false; } if ((event.keyCode==8) || //屏蔽退格删除键 (event.keyCode==116)|| //屏蔽 F5 刷新键 (event.keyCode==112)|| //屏蔽 F1 刷新键 (event.ctrlKey && event.keyCode==82)){ //Ctrl + R event.keyCode=0; event.returnValue=false; } if ((event.ctrlKey)&&(event.keyCode==78)) //屏蔽 Ctrl+n event.returnValue=false; if ((event.shiftKey)&&(event.keyCode==121)) //屏蔽 shift+F10 event.returnValue=false; if (window.event.srcElement.tagName == "A" && window.event.shiftKey) window.event.returnValue = false; //屏蔽 shift 加鼠标左键新开一网页 if ((window.event.altKey)&&(window.event.keyCode==115)){ //屏蔽Alt+F4 window.showModelessDialog("about:blank","","dialogWidth:1px;dialogheight:1px"); return false;} } 1. oncontextmenu="window.event.returnvalue=false"   将彻底屏蔽鼠标右键 2. <body onselectstart="return false">         取消选取、防止复制 3. onpaste="return false"               不准粘贴 4. oncopy="return false;" oncut="return false;"    防止复制;防止剪切 5. <link rel="Shortcut Icon" href="favicon.ico"> IE地址栏前换成自己的图标 6. <link rel="Bookmark" href="favicon.ico">  可以在收藏夹中显示出你的图标 7. <input style="ime-mode:disabled">             关闭输入法

8. 永远都会带着框架 <script language="javascript"><!--  if (window==top) top.location.href="frames.htm"; file://frames.htm为框架网页 // --></script>

9. 防止被人frame <SCRIPT LANGUAGE=javascript><!--  if (top.location!=self.location) top.location=self.location; // --></SCRIPT>

10. <noscript><iframe src=*.html></iframe></noscript>  网页将不能被另存为

使用鼠标拖动的层 <BODY BGCOLOR="#FFFFFF"> <div onmousedown="style.cursor='move';startMove(this)" onmouseup="style.cursor='auto'" style="border:1px solid #AAAAAA;background-color:#EEEEEE;width:300;height:200;position;text-align:center;">可以使用鼠标拖动</div> <script language=javascript> function startMove(objDiv) { document.attachEvent("onmousemove",moveDiv); document.attachEvent("onmouseup",endMove); document.attachEvent("onselectstart",selectNo); document["moveDiv"] = objDiv; document["startX"] = event.x; document["startY"] = event.y; document["oldX"] = objDiv.getBoundingClientRect().left; document["oldY"] = objDiv.getBoundingClientRect().top; } function moveDiv() { //try{ var obj = document["moveDiv"]; if(obj) { var l = document["oldX"];//obj.getBoundingClientRect().left;//obj.style.left// = 100//(event.x-document["startX"]); var t = document["oldY"];//obj.getBoundingClientRect().top;//obj.style.top// = 100//(event.y-document["startY"]); obj.style.position = "absolute"; obj.style.left = l + (event.x-document["startX"]); obj.style.top = t + (event.y-document["startY"]); } //}catch(e){endMove();} } function endMove() { document.detachEvent("onmousemove",moveDiv); document.detachEvent("onmouseup",endMove); document.detachEvent("onselectstart",selectNo); document["moveDiv"] = null; document["startX"] = null; document["startY"] = null; } function selectNo() { return false; } </script> </BODY>

/* 异步,动态的加载网页xml数据 */ //实际运用有更改 function GetXml(objContainer,id){ var XmlHttp=new ActiveXObject("Microsoft.XMLHTTP") objContainer.innerHTML=StateXML(Config.loading) objContainer.send="true" XmlHttp.onreadystatechange=function(){ if(XmlHttp.readyState==4){ if(XmlHttp.status==200){ var Xmldoc=XmlHttp.responseXML if(Xmldoc.documentElement.hasChildNodes()) objContainer.innerHTML=Xmldoc.transformNode(xsldoc) else objContainer.innerHTML=StateXML(Config.loading) } else objContainer.innerHTML=StateXML(Config.unavaible) } } XmlHttp.open("get",Config.Service+'?id='+id+'&tem'+Math.random(),true) XmlHttp.send() }
