Jquery-UI Dialog - on the fly without DIV

Question

I have what I suspect to be a simple question and after search I suspect the answer to my question to be no, but to double check...

Is it possible to use the Jquery

Answer 1

What about prompt

But you think that adding a div is writing a lot

you will not like these

Answer 2

This works for me. Note to avoid the body being filled with divs, I ensure the div used is removed after close:

$('<div>').prop('id', '_currentDialog').text("Please enter a Comment").dialog(
    {
        title: "Input Error",
        close: function () {
            $('#_currentDialog').remove();
        }
    }
);

Answer 3

I hope this helps somebody, you can pass html to dialog directly, like this:

$("<p>Hello World!</p>").dialog(); 

so this way you don't have to have a pre-builded div, you could use:

$("<div>My div content</div>").dialog();

EDIT: changed end tag to </div> instead of </p>

Answer 4

You can create a helper method which abstracted away the creation and configuration of the div and then called .dialog(). That would at least remove the need to duplicate code and/or create multiple divs.

Answer 5

I'm using rails and didnt like to have 2 places where to write code highly dependent. So I've modified jquery-ui dialog example like code below. See executaDialogModal()

<meta charset="utf-8">

<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript" src="jquery-ui.js"></script>
<link rel="stylesheet" type="text/css" media="screen" href="jquery-ui.css" />


<style>
    body { font-size: 62.5%; }
    label, input { display:block; }
    input.text { margin-bottom:12px; width:95%; padding: .4em; }
    fieldset { padding:0; border:0; margin-top:25px; }
    h1 { font-size: 1.2em; margin: .6em 0; }
    div#users-contain { width: 350px; margin: 20px 0; }
    div#users-contain table { margin: 1em 0; border-collapse: collapse; width: 100%; }
    div#users-contain table td, div#users-contain table th { border: 1px solid #eee; padding: .6em 10px; text-align: left; }
    .ui-dialog .ui-state-error { padding: .3em; }
    .validateTips { border: 1px solid transparent; padding: 0.3em; }
</style>
