Question

You can see what I am trying to do below. Two ways I have tried to do the same thing, but neither of these work. What is the fundamental here that I don’t get?

    <asp:HyperLink ID="HyperLink1" runat="server" 
     NavigateUrl="javascript:$('#<%= fileInput1.ClientID%>').uploadifyUpload()">
    </asp:HyperLink>

OR

    <asp:HyperLink ID="HyperLink1" runat="server" 
          NavigateUrl='<%= GetJavascriptString()%>'>
    </asp:HyperLink>

public void GetJavascriptString()
{
     return "javascript:$('#" + fileInput1.ClientID + "').uploadifyUpload();";
}

There have been several answers that work and don’t work. I think that James Curran has what I was looking for though. The reason, although I’m not sure why my code doesn’t work AND a fix for it. Thanks for all your answers.

Answer 1

I think the problem is that ASP.NET doesn’t like inserting text via <%= %> into server controls.

However, why bother with a server control for something as simple as a hyperlink? What you really want is just:

<a id="HyperLink1" 
     href="javascript:$('#<%=fileInput1.ClientID%>').uploadifyUpload()"> 
</a>

Try that.
