如何在同一div中定位next（）

Question

I have this HTML :

  <h3 class="toggle_div">
        <i class="left-image switch-icon"></i>
  </h3>

I want to change classnames when I click on the div . In this case, left-image should change to a classname right-image .

This is the jQuery I have:

$('.toggle-div').click(function(){
     $(this).siblings().next('.switch-icon').toggleClass("left-image right-image");
});

I tried this, because the code beneath only works if I put the <i> element underneath the div element I want to use to toggle. So it seems like I can't get the classname of the element that is within the div element.

$('.toggle-div').click(function(){
     $(this).next('.switch-icon').toggleClass("left-image right-image");
});

What can I use to make it work?

Answer 1

First of all your class name is wrong in JS. and then you don't need $(this).siblings().next

Just try this

$('.toggle_div').click(function(){
     $('.switch-icon').toggleClass("left-image right-image");
});

Answer 2

You can use .find() to find .switch-icon within the element which is clicked

  $('.toggle_div').click(function(){ $(this).find('.switch-icon').toggleClass("left-image right-image"); }); 

 .left-image { background-image: url('http://i.stack.imgur.com/euD9p.png'); width:20px; height:20px; background-repeat: no-repeat; } .right-image { background-image: url('http://i.stack.imgur.com/dzs9m.png'); width:20px; height:20px; background-repeat: no-repeat; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <h3 class="toggle_div"> Clicking on this text should toggle <div class="left-image switch-icon"></div> </h3> 

Answer 3

You may use .children Or .find with in the method. That should be able to retrieve the full element details based on selector.

Answer 4

Try this code

$('.toggle_div').click(function(){
                  $('div.switch-icon').toggleClass("left-image right-image");
    });
