Question

我有一个包含2列的表，其中“Give value”和其他列的“Take value”。我必须计算总给定值和总值。对于Take值，它很容易，因为它是表中记录的总数。现在我必须使用JavaScript / jquery计算Take值的总数。我该怎么做？用于计算表中的记录总数（即总给定值），如下所示

DIM giveOrTotal, assignrows, giveValue, takeValue
    '############ Convert it to an array ##########
    giveOrTotal =  RsO.GetRows
    '####### Get number of rows
    giveValue = ubound(giveOrTotal,2)

    Response.Write "<table>"
        Response.Write"<tr><td>Currently Given: "& giveValue + 1 &"&nbsp Given Value</td>"
        Response.Write"<tr><td>Currently Taken: "& takeValue + 1 &"&nbsp Taken Value</td>"
    Response.Write "<table>"

现在我正在尝试计算所取值。我可以使用javascript进行吗？

添加类和数据属性以存储行值

Response.Write "<table>"
        Response.Write"<tr><td class='give-class' data-value='"& giveValue &"'>Currently Given: "& giveValue + 1 &"&nbsp Given Value</td>"
        Response.Write"<tr><td  class='take-class'  data-value='"& takeValue &"'>Currently Taken: "& takeValue + 1 &"&nbsp Taken Value</td>"
    Response.Write "<table>"

然后在JS循环遍历行和每个类的总和

$(function(){

     var totals = {take: 0, give: 0};

     $('tr').each(function(){
        var $tds = $(this).children();
        totals.take += +$tds.filter('.take-class').data('value');
        totals.give += +$tds.filter('.give-class').data('value');
     });
     alert(totals.give);
});

如何使用jquery或javascript计算具有特定值的行数？
