Jquery - Autocomplete combobox - live()?_问答_开发者

I have a couple of autocomplete comboboxes in a div.

I have to cut it and put in into another div on some action. Upon doing so, it does not copy the events of autocomplete.

I am aware of .live() that keeps events binded to elements all the time. But how to use .live for this autocomplete combobox widget. Pls suggest?

thanks in advance.

A code sample as follows:

You are copying and pasting the HTML. You need to use detach() on the actual combobox item and then append() to add it to the new location.

EDIT: try $("#pastehere").append($("#combobox").detach());.
