checkboxlist实现单选

function  CheckBoxList_Click(sender) 
    
{
        
var container = sender.parentNode;        
        
if(container.tagName.toUpperCase() == "TD"// 服务器控件设置呈现为 table 布局(默认设置),否则使用流布局
            container = container.parentNode.parentNode; // 层次: <table><tr><td><input />
        }
        
        
var chkList = container.getElementsByTagName("input");
        
var senderState = sender.checked;
        
for(var i=0; i<chkList.length;i++{
            chkList[i].checked 
= false;
        }
     
        sender.checked 
= senderState;          
    }
