• js获取gridview模板列中textbox行列的值


    下面一个例子:在gridview中第一列输入数值,第二列输入数值,点击第三列的时候进行计算 求和,如果不符合标记为红色字体。

    如图:

    代码 :

    <html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
        <title></title>
        <script type="text/javascript">
            function setClf(con) {
                var table = document.getElementById("GridView1");
                var tr = table.getElementsByTagName("tr");
                //获取鼠标点击的元素  
                var e = event.srcElement;
                //获取元素所在的行的行号(表头行号从0开始)。注意:parentElement只适用于IE浏览器,而parentNode则符合DOM标准。  
                //var rowIndex=e.parentElement.parentElement.rowIndex ;  
                var i = e.parentNode.parentNode.rowIndex; //获取GridView控件  分别获取选定行指定列的值
                var a, b,c;
    
                a = parseFloat(tr[i].getElementsByTagName("td")[0].getElementsByTagName("input")[0].value);
                b = parseFloat(tr[i].getElementsByTagName("td")[1].getElementsByTagName("input")[0].value);
    
                //上面为获取gridview中textbox的,如果为lable则如下写法
                //  b = parseFloat(tr[i].getElementsByTagName("td")[1].getElementsByTagName("span")[0].innerText);
               
                sum1 = a+b; //计算方法改变 
                c = parseFloat(tr[i].getElementsByTagName("td")[2].getElementsByTagName("input")[0].value);
                if (sum1 != c) {
                    con.style.color = "Red";
    
                }
                else con.style.color = "black";
    
            } 
        </script>
    </head>
    <body>
        <form id="form1" runat="server">
