订单系统里有哪几种请求参数？

1、前言

请求参数注入到XXXAction的属性，分2种情况，

1.提交表单时，请求参数是表单数据——》Action的属性。

2.不提交表单，请求参数在配置文件里配置——》Action的属性。

2、提交表单

【举例：注册账户】

1.请求页面

<form name="frmRequest" method="post" action="request.jsp" onsubmit="return doRequest(this);">

2.js文件

if (dirty) {		alert("Some Required Fileds are missing or Invalid:\r\n" + msg);	} else {		$("#div_tips")				.html(						"<img src='/images/icon_loading.gif' border='0'>Process is in progress, please wait...")				.toggle(); //提示正在处理；显示提示文字		$("#div_btn_request").toggle(); //隐藏提交按钮				var params = $(form).serialize(); //提交表单之前，对表单参数进行序列化		$(".tdErrMsg").html("");		$.post(						form.action,						params,						function(json) {							if (json.success) {								$("#div_tips")										.html(												"<span style='color:339900'>Your request has been sent. We will confirm in 3 working days.</span>"); //如果正确提交页面，修改提示文字								$("#div_req_content").load("applyed.jsp", {									cust : form.president.value								}); //从服务器获取内容；传递请求参数							} else {								$("#div_tips").html(										"<b>" + json.errMsg + "</b>"); //如果提交页面出现错误，也要修改提示文字								$("#div_btn_request").toggle(); //显示提交按钮								for ( var prop in json) { //遍历json对象									try {										$("#td_" + prop).html(json[prop]); //显示错误信息									} catch (e) {									}								}							}						}, "json");	}	return false;}

3.配置文件

<fantasy>

<!-- 定义包 auth，处理客户登录等 -->

<package name='auth' extends='/' namespace='/auth' package='com.ppet.cust'

default='/json.jsp'>

<actions class='.AccountRequestAction'>			<action name='account' handler='auth'>				<result>account.jsp</result>			</action>			<action name='request' method='request' />		</actions>

4.XXXAction

/**	 * 注册会员	 * @return 结果页面字符串	 * @throws Exception	 */	public String request() throws Exception {		json = SVC.validate(getModel());		if (json == null) {			json = SVC.createAccount(f);		} else {			LOG.warn("Request Validation Fail: ".concat(json));		}		return SUCCESS;	}

5.业务逻辑类

3、不提交表单

【举例：查看所有产品（图片模式/列表模式）】

1.请求页面

<table width="100%" height="0%" cellspacing="0" cellpadding="0"	border="0" class="xiaxian">	<tbody>		<tr>			<td width="98%" height="100%"><table width="100%"					cellspacing="1" cellpadding="3" border="0">					<tbody>						<tr bgcolor="b0a697" align='center'>							<td class="prettypetMnu prettypetMnuLink"								url='/member/design/index.jsp?custCate=${customerInfo.custCate}'>NEW DESIGN</td>						    <td class="prettypetMnu prettypetMnuLink"								url='/member/prod/index.jsp?cate=&subCate=&custCate=${customerInfo.custCate}'>ALL DESIGN</td>							<td class='prettypetMnu prettypetMnuLink'								url='/member/promote/index.jsp?custCate=${customerInfo.custCate}'>PROMOTION</td>							<td class='prettypetMnu prettypetMnuLink'								url='/member/catalog/index.jsp'>CATALOG</td>							<td class="prettypetMnu prettypetMnuLink" url='/member/index.jsp'>MY								ACCOUNT</td>						</tr>					</tbody>				</table></td>		</tr>	</tbody></table>

2.js文件

$(function(){	var href=window.location.pathname;	var pos=href.lastIndexOf('/');	var path=href.substring(0,pos+1);	var reg=new RegExp("^"+path+"[^/]+$","i");	var dirty=false;	$("td.prettypetMnu").mouseover(function(){		if($(this).attr("class").indexOf("curr")==-1){			$(this).removeClass("prettypetMnuLink").addClass("prettypetMnuHover");		}	}).mouseout(function(){		if($(this).attr("class").indexOf("curr")==-1){			$(this).removeClass("prettypetMnuHover").addClass("prettypetMnuLink");		}	}).click(function(){		window.location=$(this).attr("url");	}).each(function(i,x){		if(reg.test($(this).attr("url"))) {			$(this).removeClass("prettypetMnuLink").addClass("prettypetMnuHover").addClass("curr");			dirty=true;			return false;		}	});	if(!dirty){		pos=path.indexOf("/",1);		if(pos==-1){			return;		}		path=path.substring(0,pos+1);		reg=new RegExp("^"+path+"[^/]+$","i");		$("td.prettypetMnu").each(function(i,x){			if(reg.test($(this).attr("url"))) {				$(this).removeClass("prettypetMnuLink").addClass("prettypetMnuHover").addClass("curr");				return false;			}		});	}	});

3.配置文件

<!-- 定义包 member,处理会员信息 -->	<package name='bizProd' extends='member' extended-ns='prod' default='/json.jsp' package='com.ppet.prod'>		<actions class='.CustProductAction'>			<action name='index' handler='shell' method='list'>                <param name='viewMode' value='IMG'/> //请求参数——》XXXAction的属性				<result>index.jsp</result>			</action>			<!--			<action name='listClothes' method='list'><result>listClothes.jsp</result></action>			<action name='listBed' method='list'><result>listBed.jsp</result></action>			<action name='listCarrier' method='list'><result>listCarrier.jsp</result></action>			<action name='listHarness' method='list'><result>listHarness.jsp</result></action>			<action name='viewProduct' method='edit'><result>viewProduct.jsp</result></action>			-->			<action name='list' method='list'><result>list.jsp</result></action>			<action name='image' method='list'><result>image.jsp</result></action>			<action name='view' method='edit' handler='prod'><result>view.jsp</result></action>			<action name='quick-view' method='edit'><result>quick-view.jsp</result></action>			<action name='retrieve' method='retrieve'/>			<action name='listView' handler='prod' method='list'>              <param name='viewMode' value='LIST'/>              <result>index.jsp</result>                      </action>		</actions>		<action name='size-chart' handler='prod'><result>size-chart.html</result></action>		<actions class='com.ppet.inv.CustStockAction'>			<action name='stock-index' handler='prod' ><result>../stock/index.jsp</result></action>			<action name='stock-list'  ><result>../stock/list.jsp</result></action>		</actions>	</package>
