Question

I’m trying to get the first image tag on a page. The regular expression below works on Chrome and Opera but not on Firefox.

var ex = /<img src=".+">/; 

I only got the image tags which doesn’t have the closing tags /> so this works.

This is the string that I’ll use it on:

var str = 'dd<div><img src="http://img.png" alt="" align="none"></div><div>ddd</div>'

Executing returns null in Firefox:

ex.exec(str)

But in Chrome and Opera it returns an array. In which I just have to use [0] to get the image tag.

Any ideas? Seems like Firefox doesn’t like my regex.
I only need the first match that’s why I’m not using the g option.

Answer 1

This will do

var ex = /<img[^>]+>/;
