我想使用jQuery的ui可拖动和droppable，它工作正常，如果我尝试在同一页上。但是，当我尝试拖动一个元素并放入iframe中定义的可放置区域时，它不能正常工作。它可以工作，但不在iframe的整个可投放区域，也可以在框架之外投放。jQuery的可拖动拖放到一个iframe
这里是我做了什么
我的主页：Home.html中
<!DOCTYPE html>
<html><head>
<title>jQuery UI Draggable</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>

<link href="http://code.jquery.com/ui/1.10.0/themes/base/jquery-ui.css" rel="stylesheet">
<script type="text/javascript">
$(function() {
$("#FirstDiv").draggable({ revert: "invalid",iframeFix: true });
$("#SecondDiv").draggable({ revert: "invalid" });
$("#frame").load(function() {
var $this = $(this);
var contents = $this.contents();
contents.find('.DroppableDiv').droppable({
drop: function (event, ui) { alert('dropped'); }
});
});
});
</script>
</head>
<body style="cursor: auto;" >
<div class="demo">
<div id="mainDiv" style="background-color: #FAE6B6; height:200px">
<div id="FirstDiv" style=" border-style:solid; border-width:1px; font-size:medium; height:20px; width:300px">First Div</div>
<div id="SecondDiv" style=" border-style:solid; border-width:1px; font-size:medium; height:20px; width:300px">Second Div</div>
</div>
</div>
<iframe id="frame" src="test.html" style="width: 800px; height: 400px"></iframe>
</body></html>
