Question

I am looking to use jQuery contains to run through each image on a page and check if the src tag contains a certain http value. How would I run a check on the text in the src attribute with jQuery or javacript. I have the overview of what I am attempting below:

$('img').each(function(i){
  var img = $(this),
      imgSrc = img.attr('src'),
      siteURL = "http://url.com";

  if(!imgSrc.contains(siteURL)){
     imgSrc = siteURL + imgSrc;
  }
});                         

I have a feeling regex may be the way to go just don’t know how for sure.

Answer 1

// find all img's without the siteURL, and add it
$('img:not([src^="http://url.com"])').each(function(i){
  this.src = siteURL + this.src;
});
