我正在尝试将项目从父框架拖到可放置元素中,但在 iframe 中。它在将项目放在同一帧中的可放置元素上时有效,但在跨帧尝试时,它什么也不做。
我试图解决这个问题很多次,但没有成功。
这是父框架的代码:
<html>
<head>
<title></title>
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.2/themes/smoothness/jquery-ui.css" />
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.10.2/jquery-ui.js"></script>
<style>
#draggable { width: 100px; height: 100px; padding: 0.5em; float: left; margin: 10px 10px 10px 0; }
#droppable { width: 150px; height: 150px; padding: 0.5em; float: left; margin: 10px; }
</style>
<script>
$(function() {
$( "#draggable" ).draggable();
$( "#droppable" ).droppable({
drop: function( event, ui ) {
$( this )
.addClass( "ui-state-highlight" )
.find( "p" )
.html( "Dropped!" );
}
});
});
</script>
</head>
<body>
<div id="draggable" class="ui-widget-content">
<p>Drag me to my target</p>
</div>
<div id="droppable" class="ui-widget-header">
<p>Drop here</p>
</div>
<iframe src="P1.html" width = "500px" height = "500px">
</iframe>
</body>
</html>
这是 iframe 的代码:

#droppable { width: 150px; height: 150px; padding: 0.5em; float: left; margin: 10px; }
</style>
<script>
$(function() {
$( "#draggable" ).draggable();
$( "#droppable" ).droppable({
drop: function( event, ui ) {
$( this )
.addClass( "ui-state-highlight" )

.html( "Dropped!" );
}
});
});
