如何旋转元素？

Question

Here is my code:

 $('.click').on('click', function(){ $(this).next('div').toggle(100); }); 

 .click{ cursor: pointer; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css" rel="stylesheet"/> <div class="click">click <i class="fa fa-caret-down" aria-hidden="true"></i></div> <div>something</div> 

As you see that arrow (which is next to click ) is fixed .. How can I rotate it 45° when user click on the div.test ?

Answer 1

Another option: you can use fontawesome's fa-caret-right and toggle it!

Let me know your feedback. Thanks!

 $('.click').on('click', function(){ $(this).next('div').toggle(100, 'linear', function(){ $(this).prev('div').find('i').toggleClass('fa-caret-down'); $(this).prev('div').find('i').toggleClass('fa-caret-right'); }); }); 

 .click{ cursor: pointer; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css" rel="stylesheet"/> <div class="click">click <i class="fa fa-caret-down" aria-hidden="true"></i></div> <div>something</div>

You can simply use transform CSS property. Read more about it in MDN docs .

 $('.click').on('click', function(){ $(this).next('div').toggle(100) $(this).children('i').toggleClass('rotate'); }); 

 .click{ cursor: pointer; } .rotate { transform: rotate(270deg); } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css" rel="stylesheet"/> <div class="click">click <i class="fa fa-caret-down" aria-hidden="true"></i></div> <div>something</div>
