Object-based solution for ASP paging

Objects | paging | Resolve on the forum there are many articles about ASP pagination, the basic idea is consistent, I put these netizen's thought to deepen a bit, use JavaScript to set up on a layer of object based coat, so call up don't appear disorderly, other words don't say more, see the annotation in the program.

Below is the source program:
<script Language=javascript runat=server>
function Trim (str)//Remove the trailing space of the string
{var tmpstr=new String (str)
Return Tmpstr.replace (/(^\s*) | ( \s*$)/g, "");
}
</script>


<script Language=javascript runat=server>
