元素不能擁有的z-index最高時的jQuery

Question

拖我有一個dragable項目，但它是在其他HTML元素，當我拖動它，甚至我設置.item_dragable { cursor: move; z-index: 2147483646; } 和事件dragable：

jQuerydragable.draggable({ 
    cancel: "a.ui-icon", // clicking an icon won't initiate dragging 
    revert: "invalid", // when not dropped, the item will revert back to its initial position 
    containment: "document", 
    helper: "clone", 
    cursor: "move", 
    zIndex: 2147483647 
}); 

什麼錯是嗎？我用的是最新的jQuery和jQuery UI的

感謝

，最好的辦法讓你的可拖動的項目會在一切被使用的選項appendTo（見jQuery UI doc）並將其設置爲"body"這樣的：

jQuerydragable.draggable({ 
    cancel: "a.ui-icon", // clicking an icon won't initiate dragging 
    revert: "invalid", // when not dropped, the item will revert back to its initial position 
    containment: "document", 
    helper: "clone", 
    cursor: "move", 
    zIndex: 100000, 
    appendTo: "body" 
}); 

並且當然設置了一個足夠大的z-索引以高於所有其他索引。
