How would I write this to store the text "allofthistextcaptured" with regex? i dont want "_poster" to be captured. The below javascript is exactly what I need, I just need some regex at the end to capture all the text in the src tag EXCEPT "_poster".
html
<div class="postImage"><img src="allofthistextcaptured_poster.jpg" title="" width="640" height="385" /></div>
js i have so far
var text = $(this).siblings('.postImage').find('img').attr('src');
Will a simple replace() work for you?
var text = $(this).siblings('.postImage').find('img').attr('src').replace('_poster', '');
If you want to use RegExp then you can do something like this:
var text = $(this).siblings('.postImage').find('img').attr('src').replace(/_poster./, '.');
Which looks for _poster. and replaces it with . but this is pretty-much the same thing as the first example.
Here's a demo: http://jsfiddle.net/exAXw/
Seeing as the searchable string is reduced to only the filename, you can use this regex to capture the name and the extension:
([\w]+)(?>_poster)\.([\w]+)
Just a generic replace using regEx to strip b/w k and . that is anything after _ and before .
.replace (/(_[^.*]*)/, '');
