asp.net使用Repeater控件中的全选进行批量操作实例

<script type="text/javascript">
function SelectAll(parentChk, ChildId, bigControlID) {
var oElements = document.getElementsByTagName("INPUT");
var bIsChecked = parentChk.checked;

for (i = 0; i < oElements.length; i++) {
     if (IsCheckBox(oElements[i]) && IsMatch(oElements[i].id, ChildId, bigControlID)) {
 oElements[i].checked = bIsChecked;
      }
   }
}

function IsMatch(id, ChildId, controlID) {
var sPattern = '^' + controlID + '_+.*' + ChildId + '$';
var oRegExp = new RegExp(sPattern);
if (oRegExp.exec(id))
 return true;
else
 return false;
}

function IsCheckBox(chk) {
       if (chk.type == 'checkbox') return true;
       else return false;
}
</script>
