jquery count elements with attribute

Question

Can I count the number of elements with a specific attribute?

For example all the images with the src attribute test.gif

Answer 1

Use the CSS attribute selectors to filter on the attribute

$("img[src='test.gif']").length;

the size() and length both returns the number of elements matched;

Answer 2

You want size() so something like:

something like:

$('img[src="test.gif"]').size();

Answer 3

if you want to check the presence of the attribute only

$('img[src]').length //or .size()
