javascript代碼

復(fù)制代碼代碼如下:

 
<script type="text/javascript"> 
function onClientClick(selectedId, rowIndex) 
{ 
//用隱藏控件記錄下選中的行號 
var hidden = document.getElementById("Hidden1").value=rowIndex; 

var inputs = document.getElementById("<%=GridView1.ClientID%>").getElementsByTagName("input"); 
for(var i=0; i <inputs.length; i++) 
{ 
if(inputs[i].type=="radio") 
{ 
if(inputs[i].id==selectedId) 
inputs[i].checked = true; 
else 
inputs[i].checked = false; 

} 
} 
} 
</script>
