javascript - Deal with not valid Json result in jsonp request -

i should send cross browser request , result.so use jsonp request.

my result is:

response: success message: authentication accepted 

but problem server returns json not valid , uncaught syntaxerror: unexpected identifier . use angularjs,jquery , implement request.

var ud = 'json' + (math.random() * 100).tostring().replace(/\./g, ''); window[ud] = function (o) {     success && success(o); }; document.getelementsbytagname('body')[0].appendchild((function () { debugger;      var s = document.createelement('script');     s.type = 'text/javascript';     s.src = url.replace('callback=?', 'callback=' + ud);     return s; })()); 

but same result how can handle problem.
