Hello,
This is a remote request – i.e cross site. Such ajax request are not allowed by default.
In order to do this you will need to set dataType of the edit options to jsonp.
Search the web for tis case.
Also in grid options set
… jqGrid({
…
ajaxEditOptions : { dataType: 'jsonp'},
…
});
Or make in your local server such dummy file
Regards
