如何使兩個DIV可拖動？

Question

假設我有Div1和Div2。我想讓用戶拖動Div1時，Div2也應該拖動。任何想法我如何做到這一點？

這是我走到這一步......

$(document).ready(function() { 
    $("#apDiv1").draggable(); 
    $("#apDiv2").draggable(); //<- how do I link it do Div1 ? 
}); 

編輯----------------------------- -------------------------------------

謝謝，我看着文檔，並得到到目前爲止：

<script> 
$(document).ready(function() { 
    $("#apDiv1").draggable(); 
    }); 

$("#apDiv1").bind("drag", function(event, ui) { 
       $("#apDiv2").css({ top: event.offsetY, left: event.offsetX }); 

    </script> 

似乎是對的，但...嗯，不是'工作。有任何想法嗎？

Answer 1

關於你的編輯，我做了一些改動，可以在這裏http://jsfiddle.net/9FrXr/2/

你沒有關閉「拖」綁定和替代event.offsetY和event.offsetX我用ui.offset觀看.top和ui.offset.x。拖動綁定也已被移入document.ready函數中。

$("#apDiv1").bind("drag", function(event, ui) { 
    div.css({ top: ui.offset.top + 52, left: ui.offset.left }); 
}); 

Answer 2

看看http://docs.jquery.com/UI/Draggable#event-drag看看如何綁定到一個可拖動的事件。將div1的可拖動事件綁定到更改div2座標的函數。乾杯。

再次感謝，在網頁上完全正常工作。您可以通過在www [dot] skyeye [dot] cc處移動菜單來查看它的實際運行情況。

<script> 
    $(function() { 
    $("#apDiv3").draggable(); 

    $("#apDiv3").bind("drag", function(event, masterdrag) { 
     $("#apDiv5").css({ top: masterdrag.offset.top, left: masterdrag.offset.left-20 }); 
    }); 
}); 

    </script>
