通过未嵌套的句柄拖动 div

在 JQueryUI 可拖动演示中，我可以看到您可以将句柄附加到 DIV 但如果句柄未嵌套在可拖动的父 DIV 中，它不起作用，例如

<script src="jquery-1.5.2.js"></script>
  <script src="js/jquery-ui-1.8.11.custom.min.js"></script>

  <style>    
    #hBlack
    {
        width:55px;
        height:55px;
        background-color: black;
        top:0px;
    }

    #hGreen
    {
        width:25px;
        height:25px;
        background-color: green;


    }
  </style>
  <script language="javascript" type="text/javascript">
    $(function() {
      $("#hBlack").draggable({handle:"#hGreen"});
      });
  </script>
</head>

<body>
  <div id="hBlack">
</div>
<div id="hGreen"></div>

上面的内容不会使 #hGreen 成为句柄 - 但以下内容会这样做：

<div id="hBlack">
  <div id="hGreen"></div>
</div>

本质上，我试图在另一个 DIV 移动时使一个 DIV 移动 - 我猜你可以使用新的职位实用程序来完成，但对于像我这样的新手，我发现它的记录很少

In the JQueryUI draggable demo, I can see you can attach a handle to a DIV but if the handle is not nested within the parent DIV that is draggable, it doesn't work e.g.

<script src="jquery-1.5.2.js"></script>
  <script src="js/jquery-ui-1.8.11.custom.min.js"></script>

  <style>    
    #hBlack
    {
        width:55px;
        height:55px;
        background-color: black;
        top:0px;
    }

    #hGreen
    {
        width:25px;
        height:25px;
        background-color: green;


    }
  </style>
  <script language="javascript" type="text/javascript">
    $(function() {
      $("#hBlack").draggable({handle:"#hGreen"});
      });
  </script>
</head>

<body>
  <div id="hBlack">
</div>
<div id="hGreen"></div>

The above doesn't make #hGreen the handle - but the following does:

<div id="hBlack">
  <div id="hGreen"></div>
</div>

Essentially, I am trying to make one DIV move when another moves - I guess you can do it with the new Position utility but for a newbie like me I find it poorly documented

一种可能的解决方案是将手柄放在内部，但使用 css 将其放置在外部。

Javascript:

$("#draggable").draggable({handle:"#handle"});

HTML:

 <div id="draggable">draggable
<div id="handle">handle</div>
 </div>

CSS:

#draggable{
display: block; 
height: 300px; 
width: 600px; 
background-color: gray;
}
#handle{
display: block; 
height: 50px; 
width: 600px; 
background-color: green;
position: relative;
top: -30px;
}

否则，您可能必须执行类似于多选可拖动的操作。

One possible solution could be to have the handle inside, but use css to position it outside.

Javascript:

$("#draggable").draggable({handle:"#handle"});

HTML:

 <div id="draggable">draggable
<div id="handle">handle</div>
 </div>

CSS:

#draggable{
display: block; 
height: 300px; 
width: 600px; 
background-color: gray;
}
#handle{
display: block; 
height: 50px; 
width: 600px; 
background-color: green;
position: relative;
top: -30px;
}

Otherwise, you might have to do something similar to a multiselect draggable.
