    Javascript error in IE7 and IE8 when using Ajax to get Editor

    Reply Quote

    I have an C# ASP.net page that adds the editor programmatically:

     

    protected void Page_Load(object sender, EventArgs e)

    {

          RTE.Editor ed = new RTE.Editor();

          ed.ID = "myEditor";

          Page.Controls.Add(ed);

    }

     

    This works fine in IE7 and IE8 when the page is called directly in the browser.

     

    If I try to Ajax the page, however, I get a Javascript error and the editor does not load:

     

    <html>

    <head>

    <title></title>

    <script type="text/javascript" src="/Assets/jquery/jquery.min.js"></script>

    <script type="text/javascript">

    $.post("getform.aspx",

          function (data) {  $('#pnl').html(data); });

    </script>

    </head>

    <body>

    <div id="pnl"></div>

    </body>

    </html>

     

    Error details:

     

    Line: 4

    Error: Unexpected call to method or property access.

     

    The debugger identifies this as a chunk of eval code.

    This is line 4:

     

    if(location.href.indexOf("://127.0.0.1")!=-1||location.href.indexOf("rtenocache")!=-1)

     

    Attempting to use the implicit "location" object is the issue.

    It is possible to access the "location" object explicitly in the debugger eg "window.location".

     

    This is a big problem for us, as most of our client-base use IE7.

     

    There is no bug in IE9, the editor loads successfully.

    Thanks

    Hi DanielBarratt,

     

    Can you send me the full code example page? So we can check it directly.

    Hi Ken,

     

    While preparing my reply, I discovered what was causing the problem.

     

    The aspx page which was returning the content to the AJAX request did not contain a standard ASP Form. The content returned was purely that generated by the server-side RTE.

     

    Once returned, the client-side RTE code dynamically adds a SCRIPT tag referencing the RTE "/richtexteditor/scripts/loader.js" file. IE7 and IE8 seem to require a valid form tag to be present in order to add this reference as a child to the FORM element. For some reason, IE9 did not require this.

     

    As adding this SCRIPT tag failed, the editor would not load.

     

    Simply adding a FORM tag to my ASPX page fixed the issue.

    Alternatively (as I do not want a FORM tag to be present), you can add the SCRIPT tag to the ASPX page, so not relying on it's dynamic creation on the client.

     

    Regards

    Hi,

     

    I created a new aspx-page and load the Editor using the code you mentioned above:

    richtext.aspx 

    <script language="CS" runat="server">
                protected void Page_Load()
                {
                      RTE.Editor ed = new RTE.Editor();
                      ed.ID = "myEditor";
                      Page.Controls.Add(ed);
                }

    </script>

     

    with the Event RichTextEditor_OnLoad

          <script type='text/javascript'>
                function RichTextEditor_OnLoad(editor)
                {
                    editor.SetText("test123");
                    alert(editor._config.uniqueid);
                }
          </script>

     


    Then I try to embed the richtext.aspx on an existing page using this:

    $.post('otc_web/Framework/richtext.aspx', function(data) {
                        CurrentWindow.document.getElementById("richtext").innerHTML = data;
                        alert('Load was performed.');
                      });
     

    Editor is loaded correctly, but none of the Events (e.g. RichTextEditor_OnLoad) are called. But this happens only on the embedded page. Events are called upon opening richtext.aspx directly.

     

    I tried this on IE8 and IE9.

     

    Am I missing something here? Anyone has any idea why the Events are not triggered on the embedded page?

     

    Thanks in advance for any help!
