Hello there fellow Ext'ers!
I have a simple best practices question that's a little bit over my head at the moment. In jQuery it's a good idea to save the reference to a jQuery object in order keep from initializing / running the dom selector magic every time you reference a jQuery object.
like so:
var $myObj = $("#someSelector");
Now, i'm 90% sure I should do the same in ExtJS, but I wanted to know if there was anything dangerous or wrong in the way I would like to do this.
I have a reference:
{ ref: 'userList', selector: 'usertab userlist' }
That I use repeatedly like so...
this.getUserList().doSomething()
this.getUserList().doSomething()
this.getUserList().doSomething()
this.getUserList().doSomething()
this.getUserList().doSomething()
Is it a good idea to do...
var $userList = this.getUserList() ?
