Question

I think that i read something that said that it is better for code like this:

var id1 = $(this).attr('id') 
var id2 = $(this).parent().parent().parent().parent().parent().attr('id') 
var text = $(this).text()        

..to give one variable like $this = $(this) and then use it instead of every $(this). I don’t know where i read this, so my question is that is it true?

Answer 1

yes you can

var $this = $(this);
var id1 = $this.attr('id'); 
var id2 = $this.parent().parent().parent().parent().parent().attr('id') ;
var text = $this.text();
