UserControl javascript: get control by id

[NickThissen]

I didn't.

I tried adding it in the UserControl:

<&#37;@ Control Language="vb" AutoEventWireup="false" CodeBehind="ButtonUserControl.ascx.vb" Inherits="F1TimeTrials.ButtonUserControl" %>

<script src="~/Scripts/jquery-1.4.1.js" type="text/javascript" />

<script type="text/javascript">
    function buttonClicked(sender) {
        var label = $(obj).parent().parent().find('span:eq(0)');
        alert('jup');
        label[0].innerHTML += '|';
        return false;
    }
</script>

<asp:Table runat="server">
    <asp:TableRow runat="server">
        <asp:TableCell runat="server"><asp:Button runat="server" ID="button" Text="Click!" OnClientClick="return buttonClicked(this);" /></asp:TableCell>
        <asp:TableCell runat="server"><asp:Label runat="server" ID="label" Text="" /></asp:TableCell>
    </asp:TableRow>
</asp:Table>

When I run this and click the button, there's no alert and the page posts back (so return false is never reached I guess). Doesn't work.

So I tried it on the page instead:

<%@ Page Title="" Language="vb" AutoEventWireup="false" MasterPageFile="~/Site.Master" CodeBehind="SliderTest.aspx.vb" Inherits="F1TimeTrials.SliderTest" %>

<%@ Register Src="~/Controls/ButtonUserControl.ascx" TagName="ButtonUserControl" TagPrefix="uc" %>


<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">
    
<script src="~/Scripts/jquery-1.4.1.js" type="text/javascript" />

</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
    <asp:ScriptManager runat="server" />

    <uc:ButtonUserControl runat="server" />

</asp:Content>

Now, still no alert, but the page no longer posts back. This is a little strange to me... If it doesn't post back then it has reached return false right? But why then is there no alert? And no extra |...?


I don't get it, why is this so hard? When I search for 'multiple user controls' I get at least 5-6 results with people having the exact same issue, but all they got was a few vague hints but no real solution... I don't understand how something this fundamental can be so difficult to accomplish :s
