it's not worked.
Because the showModalDialog I used to open the page of paramquery,
so $("#myGrid").PqGrid (obj) before calling $("#myGrid").PqGrid ('destroy'), IE will report false: Error: cannot call methods on pqGrid prior to initialization; attempted to call method 'destroy'.
and I'll try again window.close () the method is called before, but the memory can not be released.
Is there any other good way to free memory?
Here's my code：
// public.js Call pop-up method
var data = showModalDialog("/views/html/dj_query.html", params1, dialogStyle);
// dj_query.html
<head>
<script type="text/javascript">
