call javascript on button click

You can do something like this:

<asp:button runat="server" text="Test" OnClientClick="javascript:fnSelect('test1');" id="Button1"></asp:button>

when I do as a link the selection stays selected........but when i do it as a button, it doesnt stay selected.....i believe because of postback

I have this script

<script type="text/javascript">
    function fnSelect(objId) {
        fnDeSelect();
        if (document.selection) {
            var range = document.body.createTextRange();
            range.moveToElementText(document.getElementById(objId));
            range.select();
        }
        else if (window.getSelection) {
            var range = document.createRange();
            range.selectNode(document.getElementById(objId));
            window.getSelection().addRange(range);
        }
    }

    function fnDeSelect() {
        if (document.selection) document.selection.empty();
        else if (window.getSelection)
            window.getSelection().removeAllRanges();
    }
      </script>

Yes, it's because of the postback.

Can you use jQuery?

    $("#button1").click(function () {
        fnSelect('test1');
     });

where do i add that code?
