Regext to match part of a string

Question

I have the following code. I would like to adapt the current regex /wid=\d+(\.\d)*/g so that it matches wid=100&crop=0,0,960,650 and not just wid=100. How can I adapt it to do this?

HTML

<img class="image-resize" src="http://hugoboss.scene7.com/is/image/hugoboss/test%2Dimg?wid=100&crop=0,0,960,650" name="mainimg" id="mainimg"/>

JQUERY

 var regx = /wid=\d+(\.\d)*/g;
    currentWidth = src.match(regx);
    newWidth = 'wid=960&crop=0,0,960,650';
    newSrc = src.replace(currentWidth, newWidth);

You can use this regex.

wid=.*?(?=")

Working demo

enter image description here

As skamazin pointed in the comment you could achieve the same by using below regex (it could improve the readability):

wid=.*?"

I don't think you need that look-ahead. – skamazin Aug 18 '14 at 16:50
@skamazin it's an option. I used it to get all the content until the quote. If I removed my regex doesn't work. – Federico Piazza Aug 18 '14 at 16:51
As far as I can tell, [this](http://regex101.com/r/oS3cI4/2) is exactly the same and more readable. Perhaps my first comment wasn't clear; I meant you need the double quote but not inside a look-ahead – skamazin Aug 18 '14 at 16:57

@skamazin I see your point. Yup, you are right. I'll update my answer pointing that. Thanks for the tip. – Federico Piazza Aug 18 '14 at 17:03

How about:

var regx = /wid=[^"]+/;
