使用jQuery調整大小來顯示項目的大小

Question

想知道是否有人可以提供幫助。我在網站上使用jQuery可調整大小。我想使用僞類將調整大小/可調整大小的對象顯示爲通知樣式徽章，每次調整項目大小時都應該更新。 CSS不是問題，它獲取大小數據並顯示我遇到的問題。任何想法如何把這個關掉？任何幫助都感激不盡。我在下面的代碼片段中有錯誤，所以這裏有一個小工具可以使用。

您必須jQueryUI的庫包括在內，使投擲的（）和拖動（）工作。你已經做了之後，有一個方法停止，當resize事件完成時調用，像這樣：

$element.resizable({ 
    handles: 'e', 
    ghost: true, 
    delay: 200, 
    helper: "overmoused", 
    minWidth: 20, 
    start: function(e, ui) {}, 
    resize: function() {}, 
    stop: function(e, ui) { 
    console.log(ui.originalSize.width, ui.size.width) 
    } 
});
