Jquery获取CheckBoxList的值(兼容火狐，附js方法)RadioButtonList同样适用

 

//给CheckBoxList添加alt属性
            foreach (ListItem li in this.cblNeedTestRoom.Items) { li.Attributes.Add("alt", li.Value); }

function GetCheckBoxListValue() {
    var valuelist = ""; //保存checkbox选中值
    //遍历name以cblNeedTestRoom开头的checkbox
    $("input[name^='cblNeedTestRoom']").each(function() {            
    if (this.checked) {                
        //$(this):当前checkbox对象;                
        //$(this).parent("span"):checkbox父级span对象                
        valuelist += $(this).parent("span").attr("alt") + ",";           
        }        
     });
     if (valuelist.length > 0) {
         //得到选中的checkbox值序列,结果为400,398            
         valuelist = valuelist.substring(0, valuelist.length - 1);
     }
     return valuelist;
}

 

这里提供一个js的方法，不过无法兼容火狐浏览器

 <asp:CheckBoxList runat="server" ID="chbList" Style="font-size: 12px; line-height: 2px"
                        Visible="false">
                    </asp:CheckBoxList>

 

                var vChbid = document.getElementById("<%=chbList.ClientID %>");
                //得到所有checkbox值
                var vChbidList = vChbid.getElementsByTagName("INPUT");
                for (var i = 0; i < vChbidList.length; i++) {
                    if (vChbidList[i].checked) {
                        var text = vChbid.cells[i].innerText;
                        var value = vChbidList[i].value;alert(1);
                        // alert("选中项的text值为" + text.substring(0, 1) + ",value值为" + value);
                        perresult += text.substring(0, 1) + "|";
                    }
                }
