elrte : dialog is not a function error

When I click add image or add flash or add table button, especially when I click buttons that open a dialog box, I'm getting this error.

What is the problem do you think?

in firefox

    Error: jQuery("<div />").addClass(this.opts.class).dialog is开发者_JS百科 not a function
    source file: elrte/js/elrte.min.js
    Line: 3

 in chrome

    Uncaught TypeError: Object [object Object] has no method 'dialog' elrte/js/elrte.min.js:3

I think the problem is exactly as the error messages explain. Your jQuery object doesn't have a method named dialog.

jQuery doesn't have a dialog method by default, and apparently one hasn't been provided.

jQueryUI does have one, so you'd need to load that if that's the one you're intending to use.

Here's the demo page for jQueryUI dialogs.

You should add jQuery UI CSS Framework (jquery-ui-1.8.13.custom.css)

Open dialogs in new Elrte 1.3 not working with old version jquery UI 1.7! Last version 1.3 working just jquery UI > 1.8.3
