            <original><![CDATA[JQuery UI Draggable插件用來使選中的元素可以通過鼠標拖動.
    Draggable的元素受影響css: ui-draggable, 拖動過程中的css: ui-draggable-dragging.
    如果需要的不僅僅是拖, 而是一個完整的拖放功能, 請參閱JQuery UI 的Droppable插件, 該插件提供了一個draggable放的目標.
    所有的回調(diào)函數(shù)(start, stop, drag等事件)接受兩個參數(shù):
        event: 瀏覽器原生的事件
        ui: 一個JQuery的ui對象, 其中有以下主要屬性
            ui.helper: 正在拖動的元素的JQuery包裝對象, ui.helper.context可以獲取到原生的DOM元素.
            ui.position: ui.helper(也就是我們要拖動的元素)相對于父元素(包含自己的元素, 如果是頂層, 對應(yīng)body)的偏移, 值是一個對象{top, left}----也就是可以用ui.position.top獲取到該元素與父元素的top當前偏移
            ui.offset: 與ui.position同意, 這里表示的是和瀏覽器內(nèi)容區(qū)域左上邊界的偏移(注意, 是內(nèi)容區(qū)域, 而不是html的body區(qū)域. html的body在默認情況下, 各種瀏覽器中都會相對offset有偏移的.)]]></original>

            true表示ui-draggable樣式被添加到該元素.

            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選項默認是'*', 看起來數(shù)draggable_a, draggable_b可以自由的放入到droppable_a和droppable_b中, 但是, 由于scope的約束, draggable_a只能放入到droppable_a, draggable_b只能發(fā)乳到droppable_b中.
            注意: 這個選項就和變量的名稱空間的意義類似. 默認值是'default', 說明如果不指定, 大家都還是有scope的, 名字是default而已.]]></description>
