Easiest way is to define a hidden field and copy the value of the variable
into it on postback.

something like this:
<input type="hidden" runat="server" id="hiddenVaria bleValue" />
<asp:Button ..... onClientClick=" return copy_variable() ;" />

where
<script>
var hidden_field_id = "<%=hiddenVaria bleValue.Client ID%>";
function copy_variable()
{
document.getEle mentById(hidden _field_id ).value =
your_txt_value_ here;
return true;
}
</script>
