做个记录

cript language="javascript" type="text/javascript">
function Select(all) {
if (all != undefined) {
var chks = document.getElementsByTagName("input");
for (var i = 0; i < chks.length; i++) {
if (chks[i].id.indexOf("chkItem") >= 0 && chks[i].type == "checkbox") {
chks[i].checked = all.checked;
}
}
}
return false;
}
</script>
