From: aspfun via DotNetMonster.com on 2 Mar 2010 08:53 How to call the function validate() on the form loading? There is a form in which another program will fill some text boxes automatically. I need this JS function to test the value of text boxes and give user a alert if any text box is empty. <script type="text/javascript"> function validate() { var t1 = document.getElementById('<%=txtOrderProduct.ClientID%>'); var t2 = document.getElementById('<%=txtOrderBy.ClientID%>'); if(t1.value == "" && t2.value == "") { alert("Empty'); } } </script> -- Message posted via DotNetMonster.com http://www.dotnetmonster.com/Uwe/Forums.aspx/asp-net/201003/1

It is working. But how to add it into a content page with master page? There is no body tag. -- Message posted via DotNetMonster.com http://www.dotnetmonster.com/Uwe/Forums.aspx/asp-net/201003/1
