changing the img src with jquery

Question

The html structure I have is something like:

<ul id="something">
  <li>
    <a href="">
      <img src="http://domain.com/directory/file1-128x79.jpg">
    </a>
  </li>
  <li>
    <a href="">
      <img src="http://domain.com/directory/file2-128x79.jpg">
    </a>
  </li>
  <li>
    <a href="">
      <img src="http://domain.com/directory/file3-128x79.jpg">
    </a>
  </li>
</ul>

I'm trying to change the filename from file#-128x79.jpg to file#-896x277.jpg .

I don't know how to take the dynamically generated filename and search and replace for the src changes.

I found my way to replacing the whole src with 'none' to make sure I got it right so far, but I don't know how to do the rest.

$('#something').removeAttr('id').prop('class', 'some-class').find('img').prop('src', 'none');

Answer 1

You can replace the src for each img by first selecting all the images with a selector and then using the attr callback to replace the contents:

$('#something img').attr('src',function(i,e){
    return e.replace("-128x79.jpg","-896x277.jpg");
})

Answer 2

you can assign an id to your image tag like

<img id ="pic" src="http://domain.com/directory/file3-128x79.jpg">

then in jquery use

$('#pic').attr('src', 'file#-896x277.jpg');

Answer 3

DEMO

$('img').hover(function(){ // or any other method
    this.src = this.src.replace("128x79", "200x60");         
}); 

Answer 4

您应该添加.children()之前.find('img')

$('#something').removeAttr('id').attr('class', 'some-class').children().find('img').attr('src', 'none');

Answer 5

Note : try the following here mouse over is just for the demo purpose only

$(function() {
    $("something li a img")
        .mouseover(function() { 
            var src = "over.gif";
            $(this).attr("src", src); // change the image source
        })

});

Answer 6

使用attr怎么样：

this.removeAttr('id').prop('class', 'featured-images').find('img').attr({‘src’:'file#-896x277.jpg’});

Answer 7

$('#something img').attr('src',$('#something img').attr('src').replace(x,y))
