Jquery ui Dialog: cannot call methods on dialog prior to initialization

dialogjqueryjquery-ui-dialog

I have an app on jquery 1.5 with dialogs worked fine.
While I have a lot of .live handlers, I changed this to .on.
For that, I have to update jquery (now 1.8.3 an jquerui 1.9.1).

Now, I got: Error: cannot call methods on dialog prior to initialization; attempted to call method 'close'

Following is the code:

Javascript

var opt = {
        autoOpen: false,
        modal: true,
        width: 550,
        height:650,
        title: 'Details'
};

$(document).ready(function() {
$("#divDialog").dialog(opt);
    $("#divDialog").dialog("open");
...

html code

<div id="divDialog">
<div id="divInDialog"></div>
</div>

Any idea why this might be happening?

Try this instead

$(document).ready(function() {
  $("#divDialog").dialog(opt).dialog("open");
});

You can also do:

var theDialog = $("#divDialog").dialog(opt);
theDialog.dialog("open");

That's because the dialog is not stored in $('#divDialog'), but on a new div that is created on the fly and returned by the .dialog(opt) function.

Javascript – How to manage a redirect request after a jQuery Ajax call

I read this question and implemented the approach that has been stated regarding setting the response HTTP status code to 278 in order to avoid the browser transparently handling the redirects. Even though this worked, I was a little dissatisfied as it is a bit of a hack.

After more digging around, I ditched this approach and used JSON. In this case, all responses to AJAX requests have the status code 200 and the body of the response contains a JSON object that is constructed on the server. The JavaScript on the client can then use the JSON object to decide what it needs to do.

I had a similar problem to yours. I perform an AJAX request that has 2 possible responses: one that redirects the browser to a new page and one that replaces an existing HTML form on the current page with a new one. The jQuery code to do this looks something like:

$.ajax({
    type: "POST",
    url: reqUrl,
    data: reqBody,
    dataType: "json",
    success: function(data, textStatus) {
        if (data.redirect) {
            // data.redirect contains the string URL to redirect to
            window.location.href = data.redirect;
        } else {
            // data.form contains the HTML for the replacement form
            $("#myform").replaceWith(data.form);
        }
    }
});

The JSON object "data" is constructed on the server to have 2 members: data.redirect and data.form. I found this approach to be much better.

Html – How to remove close button on the jQuery UI dialog

I have found this worked in the end (note the third line overriding the open function which find the button and hides it):

$("#div2").dialog({
    closeOnEscape: false,
    open: function(event, ui) {
        $(".ui-dialog-titlebar-close", ui.dialog || ui).hide();
    }
});

To hide the close button on all dialogs you can use the following CSS too:

.ui-dialog-titlebar-close {
    visibility: hidden;
}
