推荐答案

确切地说出您的需求真的很困难.

It is just really tough to tell exactly what you need.

听起来您的javascript中有动态生成的元素，而使这些元素可拖动却遇到了麻烦.

I sounds like you have elements that are generated dynamically in your javascript, and you are having trouble making those draggable.

我认为这意味着您已经成功使页面上的其他元素(可动态添加)变为可拖动状态.

I assume this means that you have successfully made other elements on the page draggable that were not added dynamically.

如果是这种情况，则在将新元素添加到页面之前，只需在添加新元素之前对其进行相同的draggable()调用即可.

IF this is the case, before you add your new element to the page, just do the same draggable() call on it before you add it.

   // Create new element
var $newElement = $("<div class='suggestion'>I'm a suggestion</div>");

   // Make it draggable
$newElement.draggable();

   // Append it to your container
$newElement.appendTo('.suggestions');

如果这不是您的意思，请在您的问题中非常清楚和详细.还请添加一个代码示例，该示例经常解释很多. :o)

If this is not what you mean, then please be very clear and detailed in your question. Please also add a code example, which often explains much. :o)
