如果具有特定的类或ID,则将查询字符串添加到Image Source(img src)

I want this in either PHP or JS. Its like, if img has particular class them a query string will be appended to its source url. Lets assume, the particular class is 'hello' & query string is '?source=fb' So, if img has class 'hello' -

<img class="hello" src="">

The PHP should check & append it to the img src.

Any function that can do this?

    You can use the attr() method to achieve this by providing a function to amend the current attribute value. Try this:

    $('.hello').attr('src', function(i, src) {
        return src + '?source=fb';

    You can try this by Jquery. Just give another class to your image tag, assume the class 
    given is "abc", it should be like :
    <img class="abc hello" src="">
      var image_src = $('.abc').attr('src');
