checkbox全选

经常会碰到checkbox全选的情况,留个模板,以后备用:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>全选与反选</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<script language="javascript">
// --列头全选框被单击---
function ChkAllClick(sonName, cbAllId){
    var arrSon = document.getElementsByName(sonName);
 var cbAll = document.getElementById(cbAllId);
 var tempState=cbAll.checked;
 for(i=0;i<arrSon.length;i++) {
  if(arrSon[i].checked!=tempState)
           arrSon[i].click();
 }
}

// --子项复选框被单击---
function ChkSonClick(sonName, cbAllId) {
 var arrSon = document.getElementsByName(sonName);
 var cbAll = document.getElementById(cbAllId);
 for(var i=0; i<arrSon.length; i++) {
     if(!arrSon[i].checked) {
     cbAll.checked = false;
     return;
     }
 }
 cbAll.checked = true;
}

</script>
</head>
