JQuery UI: How to call a widget function with its namespace

Question

I created two custom JQuery UI widgets with same name but with different namespaces as given below: First widget:

$.widget('finance.dialog',{....}); // this was created in the file jquery.finance.dialog.js

Second widget:

$.widget('hr.dialog',{.....}); // this was created in the file jquery.hr.dialog.js

Apart from these two, JQuery UI has its own dialog widget (ui.dialog) in the namespace ui.

My question is: Which dialog widget will be called when i call the following in a web page as given below?

$('div#something').dialog(); 

Please note I include all the three widget variants in the web page.

I understand there are conflicts in the above scenario. How can we invoke a widget function with its namespace so that there will not be any conflicts?

Answer 1

I had the same question, but I don't think it's possible to invoke a jquery ui widget with the namespace.

If I understand correctly from this: http://bugs.jqueryui.com/ticket/7489 By defining widgets with the same name, it's by design to overwrite earlier definitions. Because regardless of namespace, the widgets are mapped with their name to $.fn.

As suggested in the bug ticket you can use the bridge function to create a unique mapping to the specific namespaced widget and call it using the unique name.

In your case, it can be like this:

$.widget.bridge( "finance_dialog", $.finance.dialog );
$.widget.bridge( "hr_dialog", $.hr.dialog );

// then call it with...
$( "div#something" ).hr_dialog(); 

I suppose another way would be to create unique widget names in the first place.

You can invoke a jQuery UI widget by its namespace like this:

$.ui.dialog(null, $('div#something'));  // Default jQ UI dialog
$.finance.dialog(null, $('div#something'));  // Your first custom dialog
$.hr.dialog(null, $('div#something'));  // Your second custom dialog

Use the first parameter, which is null in the example above, to send any options to the widget.
