【jQuery：遍历相同class的所有值，遍历某一列td的值】

jsp代码：

Html代码

<c:forEach var="main" items="${mainPage.list }">

<tr>

<td><a class="sceneStr_td">${main.sceneStr }</a></td>

<td class="concern">${main.concernedNumber }</td>

<td class="noConcern">${main.noConcernedNumber }</td>

<td class="validateNumber">${main.validateNumber }</td>

<td>${main.createTime }</td>

<td>${main.delFlag==0?'允许':'不允许' }</td>

<td>

<a href="${main.url }" target="_blank">二维码链接</a>

</td>

</tr>

</c:forEach>

<tr class="count_main">

<th style="text-align: center;">统计:</th>

<td class="count_concern">0</td>

<td class="count_noConcern">0</td>

<td class="count_validateNumber">0</td>

<td></td>

<td></td>

<td></td>

</tr>

复制代码

js代码：

Html代码

var main_list_size = $(".main_list_size").val();//获取主单循环大小

main_list_size = parseInt(main_list_size);

var count_concern = parseInt(0);

var count_noConcern = parseInt(0);

var count_validateNumber = parseInt(0);

if(main_list_size<=0){

$(".count_main").hide();//没有数据时，隐藏该行

}else{

var concern = $(".concern noConcern validateNumber");

for(var i=0;i<main_list_size;i++){

count_concerncount_concern = count_concern+ parseInt($(".concern").eq(i).html());

count_noConcerncount_noConcern = count_noConcern + parseInt($(".noConcern").eq(i).html());

count_validateNumbercount_validateNumber = count_validateNumber + parseInt($(".validateNumber").eq(i).html());

}

$(".count_concern").html(count_concern);

$(".count_noConcern").html(count_noConcern);

$(".count_validateNumber").html(count_validateNumber);

$(".count_main").show();//有数据时，显示该行

}

复制代码

这样，下面的统计信息就全出来了​
