C# MVC4 怎么实现全选checkbox。_html/css_WEB-ITnose

        $("#chkAll").click(function () {            if (this.checked) {                $("input[name='chkId']").each(function () { this.checked = true; });            }            else {                $("input[name='chkId']").each(function () { this.checked = false; });            }        });

   <input type="checkbox" id="chkAll" />全选   <input type="checkbox" name="chkId" value="id1" />   <input type="checkbox" name="chkId" value="id2" />

        window.onload = function () {            $("#chkAll").click(function () {                $("input[name='chkId']").attr("checked", this.checked);            });        }
