如何旋轉元素？

Question

這裏是我的代碼：

$('.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>

正如你看到箭頭（這是旁邊click）固定..我怎樣才能將其旋轉45°，當用戶點擊div.test？

另一種選擇：你可以使用fontawesome的fa-caret-right和撥動它！

讓我知道您的反饋。謝謝！

$('.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>

您可以簡單地使用transform CSS屬性。在MDN docs閱讀更多關於它的信息。

$('.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>
