jquery.ui.draggable中文文档

注意事项:
    1. 以下格式为既定的格式, 为了统一性, 需要修改时, 大家商议
    2. 格式中的所有项都是选填, 如果没有, 不写就是了.
    3. 由于是XML格式的, 所以, 所有标签中间填写文本的地方(最重要是代码, 一定要加, 不然以后解析有困难), 都需要加上
<!--[CDATA[这中间写内容]]>
    4. 翻译过程中, 一块对应的是一个<translate />标签.
    5. 希望大家工作愉快.

            <original><![CDATA[JQuery UI Draggable插件用来使选中的元素可以通过鼠标拖动. 
    Draggable的元素受影响css: ui-draggable, 拖动过程中的css: ui-draggable-dragging. 
    如果需要的不仅仅是拖, 而是一个完整的拖放功能, 请参阅JQuery UI 的Droppable插件, 该插件提供了一个draggable放的目标. 
    所有的回调函数(start, stop, drag等事件)接受两个参数: 
        event: 浏览器原生的事件 
        ui: 一个JQuery的ui对象, 其中有以下主要属性 
            ui.helper: 正在拖动的元素的JQuery包装对象, ui.helper.context可以获取到原生的DOM元素. 
            ui.position: ui.helper(也就是我们要拖动的元素)相对于父元素(包含自己的元素, 如果是顶层, 对应body)的偏移, 值是一个对象{top, left}----也就是可以用ui.position.top获取到该元素与父元素的top当前偏移 
            ui.offset: 与ui.position同意, 这里表示的是和浏览器内容区域左上边界的偏移(注意, 是内容区域, 而不是html的body区域. html的body在默认情况下, 各种浏览器中都会相对offset有偏移的.)]]></original>

            true表示ui-draggable样式被添加到该元素. 
            false表示ui-draggable样式不被添加到该元素.]]></description>

            例如: 
            $('#draggable_a').draggable({scope: 'a'}); 
            $('#draggable_b').draggable({scope: 'b'}); 
            $('#droppable_a').droppable({scope: 'a'}); 
            $('#droppable_b').droppable({scope: 'b'}); 
            droppable控件的accept选项默认是'*', 看起来数draggable_a, draggable_b可以自由的放入到droppable_a和droppable_b中, 但是, 由于scope的约束, draggable_a只能放入到droppable_a, draggable_b只能发乳到droppable_b中. 
            注意: 这个选项就和变量的名称空间的意义类似. 默认值是'default', 说明如果不指定, 大家都还是有scope的, 名字是default而已.]]></description>
