本文详细介绍了如何使用 jQuery EasyUI 实现元素的拖拽功能，包括通过 HTML 标记和 JavaScript 初始化拖拽组件的方法。同时，还探讨了拖拽组件的各种属性设置，如光标样式、延迟时间等，并提供了示例代码。

Draggable

Override defaults with $.fn.draggable.defaults.

Usage Example

Create a draggable element from markup.

<divid="dd"class="easyui-draggable"data-options="handle:'#title'"style="width:100px;height:100px;">
<divid="title"style="background:#ccc;">title</div>
</div>

Create a draggable element using javascript.

<divid="dd"style="width:100px;height:100px;">
<divid="title"style="background:#ccc;">title</div>
</div>

$('#dd').draggable({
handle:'#title'
});

Description

Default

proxy

null或string(比如'clone')或function

A proxy element to be used when dragging, when set to 'clone', a clone element is used as proxy. If a function is specified, it must return a jQuery object.

//1.默认是null

//2. 可用'clone'
$('.dragitem').draggable({
	proxy: 'clone'
});



//3. 可用function
$('.dragitem').draggable({
	proxy: function(source){
		var p = $('<div style="border:1px solid #ccc;width:80px"></div>');
		p.html($(source).html()).appendTo('body');
		return p;
	}
});
