Question

Which way is better: $('#item1 img[src]').qtip( {..}); -OR- $('#item1').qtip( {..}); ?
It works both ways. Would you recommend to use img[src] as a part of the selector? Is it normal?
Thank you.

Answer 1

Those are two separate things:

$('#item1 img[src]').qtip( {..});

Selects an image element within an element with id item1.

$('#item1').qtip( {..});

Selects an element with id item1.

What does img[src] do?

I only know that format when adding a src to it. Otherwise it does just nothing if it works.

$('img[src*="you_src_you_want_to_select"]')
