在jQuery中動態添加元素作爲可排序句柄

Question

我有以下代碼。在懸停的div我添加一個按鈕，並希望使該按鈕作爲拖動手柄。但由於某種原因，這種阻力似乎並不奏效。我究竟做錯了什麼？

$(document).ready(function() { 
 
    var active = 0; 
 
    jQuery(document).on("mouseover", ".mfx-container", function(e) { 
 
    if (active == 0) { 
 
     active = 1; 
 
     jQuery(".mfx-container").css("outline", "none"); 
 
     jQuery(this).css("outline", "2px solid #DDE5EC"); 
 
     jQuery(".editor-hover-buttons").remove(); 
 
     jQuery(this).append('<button class="editor-hover-buttons move-button" type="reset">Move</button>'); 
 

 
     jQuery(".mfx-wrapper").sortable({ 
 
     handle: ".move-button" 
 
     }); 
 

 

 
    } 
 
    }) 
 
    jQuery(document).on("mouseout", ".mfx-container", function(e) { 
 
    if (active == 1) { 
 
     active = 0; 
 
    } 
 
    }) 
 

 

 

 

 
})

.mfx-container { 
 
    min-height: 100px; 
 
    position: relative; 
 
} 
 
.delete-block-button { 
 
    position: absolute; 
 
    top: 10px; 
 
}

Answer 1

首先，gpgekko指出，move-block-button很可能是move-button一個錯字。

其次，jQuery UI可排序似乎不適用於button作爲其句柄。

如果您將button更改爲div，那麼它可以工作。請參閱http://jsbin.com/kiyozutodo/edit?html,js,output瞭解相關演示。
