Ajax is used for JSONP cross-domain requests because the callback function name of the requested party cannot be modified. Several different JSONP requests will appear on this page, but their callback function names are all the same, _ Callback. Think of setting the JSONP parameter of AJAX. But it didn't work at all. Finally, I stumbled upon that jsonpcallback is case-sensitive. Must be jsonpCallback, not jsonpcallback

The copy code is as follows:

$.ajax ({

Url: 'http://www.zbphp.com/j.php?act=json&tm=',

DataType: 'JSONP'

JsonpCallback:'_ GroupMember_Callback'

Success: function (json) {

}

});
