Use regex to get image URL in HTML/Js

I want to get some URLs of ima开发者_运维技巧ges in Js/HTML:

var a = "http://sub.domain.com/uploads/files/11-11-2011/345301-574-1182-393/2202.jpg";
var b = "http://sub.domain.com/uploads/files/23-11-2011/234552-574-2321-232/asd.png";

Looking for solution that will detect image url. So the output will be:

http://sub.domain.com/uploads/files/11-11-2011/345301-574-1182-393/2202.jpg
http://sub.domain.com/uploads/files/23-11-2011/234552-574-2321-232/asd.png

Thanks!

Based off the information you've given, this should work:

(https?:\/\/.*\.(?:png|jpg))

You can add more extensions by adding |ext after jpg. This will allow for strings with https as well.

Note: You may want to use the case insensitive modifier i to make the capture more inclusive. This would look like:

/(https?:\/\/.*\.(?:png|jpg))/i

A little late to the party, but in trying to do something similar to the OP, I created the following regex, which seems to handle relative links as well as absolute ones:

/([a-z\-_0-9\/\:\.]*\.(jpg|jpeg|png|gif))/i

Try this:

/"(http://[^"]*?\.(jpg|png))"/g

$1 is what you want.

I created this regex a few days ago:

/^https?:\/\/.*\/.*\.(png|gif|webp|jpeg|jpg)\??.*$/gmi

The ones provided by others in this post work, but will not check for query strings

Example of this regex:

  static checkForImage(url){
    let regex = /^https?:\/\/.*\/.*\.(png|gif|webp|jpeg|jpg)\??.*$/gmi
    let result;
    if (url.match(regex)){
      result = {
        match: url.match(regex)
      }
    } else {
      result = false;
    }
    return result;
  }
checkForImage('https://images-ext-2.discordapp.net/external/yhycJKw8ohsysnU6CBDLQPV4979oQINVmv-fRfu-jL8/%3Fsize%3D2048/https/cdn.discordapp.com/avatars/490535372393021469/a_9e9d0e575eee0221e759257e259681af.gif')

A super strict solution to this would be:

/(http[s]*:\/\/)([a-z\-_0-9\/.]+)\.([a-z.]{2,3})\/([a-z0-9\-_\/._~:?#\[\]@!$&'()*+,;=%]*)([a-z0-9]+\.)(jpg|jpeg|png)/i

var regex = /(http[s]?:\/\/.*\.(?:png|jpg|gif|svg|jpeg))/i;

This is the result you want
