Title: pre-process an event [Solved]
Post by: devnull on December 05, 2014, 04:50:34 AM

Is it possible to process all events for an object and then allow subsequent occurrences to also process the event afterwards:

Code:

$.extend($.fn.tabs.defaults, {
  onSelect: function(title){
    ...do something for all events
  }
})

$('#mytab').tabs({
  onSelect: function(){
   ...do something just for this event
  }

})

so that "...do something for all events" is always processed first for all tabs even if they have a onSelect() function ?

Please try this:

Code:

$('#mytab').tabs({
	onSelect:function(title){
		$.fn.tabs.defaults.onSelect.call(this, title);
		console.log('do something just for this event');
	}
})

Thanks so much, but I am trying to do it the other way around so that I do not have to change all of the existing pages which already use the tabs.onChange() event.

Is it possible to extend the tabs so that it performs the pre-process before calling the onChange() without having to modify all of the other pages that make use of the onChange event ?

I guess what I am really looking for is an onBeforeSelect() type event.

The 'onBeforeOpen' event of panel fires before the 'onSelect' event of tabs. It can be used to perform your pre-processing before selecting a tab panel.

Code:

var mytab = $('#mytab').tabs({...});  // create the tabs component
$.each(mytab.tabs('tabs'), function(index,p){
	p.panel('options').onBeforeOpen = function(){
		console.log('do something before selecting the panel');
	}
});
