unable to set values of select tag in jquery mobile
I had created a select tag in html(SelectTest.html) with some values.What i'm trying to do is after selecting any value from select tag, i need the page to be refreshed and pass the selected option as parameter to url.
Then i need to set this as selected value once the page is refreshed. I'm not sure whether this problem is related to jQuery mobile.

From the jquery mobile docs:
If you manipulate a select via JavaScript, you must call the refresh method on it to update the visual styling. Here is an example:
var myselect = $("select#foo"); myselect[0].selectedIndex = 3; myselect.selectmenu("refresh");
So basically you just need to call refresh on it. Does this help?
For your code you can chain it like this
$('#lang').val(aval).selectmenu("refresh");
加载中,请稍侯......
