Question

I have this javascript code:

    function checkUploadedFile() {
        var inputFile = $("#fuUploadProfile").val();
        if (inputFile != "") {
            __doPostBack('btnUploadProfile', '');
        } else {
            $("#lblMessage").show();
            return false;
        }
    }

here are the controls:

<asp:Label ID="lblMessage" runat="server" CssClass="srn_error">*Required</asp:Label>
<asp:FileUpload ID="fuUploadProfile" runat="server" CssClass="srn_file" />    
<asp:Button ID="btnUploadProfile" ClientIDMode="Static" runat="server" Text="Upload" class="srn_button" OnClientClick="checkUploadedFile();" />

Even though I already have selected a file to upload, I get the “Microsoft JScript runtime error: Access is denied.” only when using IE9.

What am I doing wrong?

Answer 1

after much thorough searching of the code, it was due to a javascript that was loaded, which was triggering the ‘click’ event of the asp.net FileUpload control. it seems that IE does not play well with javascript events that trigger a DOM control.

after I disabled the javascript function, it was working perfectly.
