取用户控件中的checkbox

http://www.itzhe.cn/news/20080129/66899.html

 ？？

1.取选用户控件的ID,

2.取得用户控件中input ,其实就回到平时全选与不选.

aspx页面的js脚本这样来:

    function CheckValue()

         {
            //在JS端调用CheckBoxList

             var chkObject = document.getElementById('<%=chkProjStatus.ClientID%>');

             var chkInput =chkObject.getElementsByTagName("INPUT");

             var arrListValue = chkObject.ListValue.split(',');

             var count = arrListValue.length;

             var strCheckChecked = ""; 

             var arrCheckChecked;

             var chkValue = "";
              
//每次点击CheckBoxList的一个Item，都循环把所有Item的选中状态按0、1标志，存入一个变量，最后再根据这个标志来决定checkboxlist中要取的值
        
                for (var i=0; i< chkInput.length; i  ) 
                { 
                    if(chkInput[i].checked)
                    {
                        strCheckChecked = strCheckChecked   "1"   ",";
                    }
                    else
                    {
                        strCheckChecked = strCheckChecked   "0"   ",";
                    }
               } 
                arrCheckChecked =  RTrim(strCheckChecked).split(',');
                 for(var j = 0; j < count; j  )
                 {
                     if(arrCheckChecked[j] == "1")
                     {
                         chkValue  = arrListValue[j]  ",";
                     }
                 } 
                 chkValue =  RTrim(chkValue); 
                 alert(chkValue); 
         }     
        //假如有则移除末尾的逗号

        function RTrim(str) 
        { 
            if(str.charAt(str.length-1)==",")

               return str.substring(0,str.length-1); 
            else
               return str; 
        }

OK,这样就搞定了:)

我上面是参考了博客园上 "人生苦短破茧"和"sammy知识库栖宇惊鸿的天下"写的关于checkboxlist用js取值的文章,综合了下,这样调用应该还是比较方便的,大家觉得有改进的地方回贴好了
