Question

I have one function:

function myFunction(){
var id = $(this).attr('id');
}

Now sometimes, myFunction gets called with $(this) as the context but sometimes the context is just ‘this’.

In one line how can I do something similar to this:

if(this == $(this)){
var e = $(this);
}

Basically a test to see if ‘this’ is a jQuery ‘this’ or a JS ‘this’.

Possible?

Answer 1

if (this.jquery) { // refers to jQuery version
  // jQuery object
}

Alternatively:

if (this instanceof jQuery) { // prototype chain
  // jQuery object
}

However, as others have said, it doesn’t really matter, $(this) will work whether or not this is already a jQuery object or a DOM element.
