关于JS获取struts iterate对象及提醒功能
今天下午要做项目中的一个小功能：付款提醒功能，到付款时间用红色显示，做成之后如下图

如下代码是struts iterate对象：

			<table width="100%" border="1" class="listtable" id="table">
				<tr class="listheader">
					<td width="30" align="center" nowrap>
						序号
					</td>
					<td width="30" align="center" nowrap>
						<input type="checkbox" name="allbox" onclick="allboxclick()">
					</td>
					<td width="30" align="center" nowrap>
						编辑
					</td>
					<td width="100" align="center" nowrap>
						<gpt:PageSortColumn column="obj.sn"
							htmlproperty="class='sortcolumn'">合同编号</gpt:PageSortColumn>
					</td>
					<td width="100" align="center" nowrap>
						<gpt:PageSortColumn column="obj.name"
							htmlproperty="class='sortcolumn'">合同名称</gpt:PageSortColumn>
					</td>
					<td width="100" align="center" nowrap>
						<gpt:PageSortColumn column="obj.money"
							htmlproperty="class='sortcolumn'">金额</gpt:PageSortColumn>
					</td>
					<td width="100" align="center" nowrap>
						<gpt:PageSortColumn column="obj.deadline"
							htmlproperty="class='sortcolumn'">期限</gpt:PageSortColumn>
					</td>
					<td width="100" align="center" nowrap>
						<gpt:PageSortColumn column="obj.principal"
							htmlproperty="class='sortcolumn'">负责人</gpt:PageSortColumn>
					</td>
					<td width="100" align="center" nowrap>
						<gpt:PageSortColumn column="obj.paytime"
							htmlproperty="class='sortcolumn'">付款时间</gpt:PageSortColumn>
					</td>
				</tr>
				<logic:iterate id="obj" name="OBJLIST" scope="request">
					<tr class="listrow" onclick="hL(this)" onmouseout="out(this)">
						<gpt:TD><%=++i%></gpt:TD>
						<td width="30" align="center">
							<input type="checkbox" name="delbox" onclick="delboxclick();"
								value="<bean:write name="obj" property="id"/>" />
						</td>
						<td width="30" align="center">
							<img src="../../resources/images/icon/icon_modify.gif"
								class="icon"
								onclick="mod(400,380,<bean:write name='obj' property='id'/>);" />
						</td>
						
							<bean:write name="obj" property="sn" />					
						
							<bean:write name="obj" property="name" />
						
							<bean:write name="obj" property="money" />
					
							<bean:write name="obj" property="deadline" />
					
							<bean:write name="obj" property="principal" />
					
							<bean:write name="obj" property="paytime" />
					
					</tr>
				</logic:iterate>
			</table>

下面是在窗体自动加载时调用JS来提醒是否到了付款日期（我这里是做提前一天提醒）
代码如下：

    	// 显示红色
   		window.onload = function(){
   		
   			//得到这个表
   			var array = document.getElementById("table");
   			
   			//得到这个表共有多少行
   			var length = array.rows.length - 1;
   			var i=1;
   			
   			//循环判断是否超过付款日期
   			for(i=1; i <= length; i++){
   				var date = new Date();
   				var year = date.getFullYear();
   				var month = date.getMonth()+1;
   				var day = date.getDate() - 1;
//因为我这里是第7列，所以cells[6]
   				var time = array.rows[i].cells[6];
   				var timeArray = new Array();
   				timeArray[0] = year;
   				timeArray[1] = month;
   				timeArray[2] = day;
   				var j = 0;
   				var k = 0;
   				var subStrOfTime = time.innerText.substr(0,10);
   				for(j = 0; j < subStrOfTime.split("-").length; j++){
   					var a = subStrOfTime.split("-")[j];
   					// 格式化后相比较
   					if(a.replace(/\b(0+)/gi,"")<=timeArray[j])
   					{	
   						k ++ ;
   					}
   				}
   				if(k == 3){
   					array.rows[i].style.backgroundColor="#FF6900";
   				}
   			}
