Extjs and jquery event processing

JqueryThe event is simple. For example, we want to listen to the button click event.
$ ('# BTN'). Click (function (){

Alert ('clicked ')

})

To trigger the Click Event of the button, $ ('# BTN'). Click () is OK.

Extjs is a bit cool

You can add the following to config:

{Component code...

Xtype: 'button ',

Listeners :{

Click: function (){}

}

} // Component over

Many components have the default handler, for example, buttons can be directly:

{Component code...

Xtype: 'button ',

Handler: function (){}

}

} // Component over

You can also use the addlistener method of the object.

Ext. getcmp ('btn '). addlistener ('click', function (){})

Trigger:

Ext. getcmp ('btn '). fireevent ('click', argS)

However, handler cannot be fired in version 3.2, which seems like a bug!
