xmlhttprequest cannot load No 'Access-Control-Allow-Origin' AJAX跨域请求解决方法

今天使用JQ的AJAX请求数据,出现了下面的错误
$(".content").on('click', '.synData', function() { var _this=$(this); var response=_this.prev().val(); var idcard=_this.prev().prev().val(); $.ajax({ type:'POST', url:'http://v.juhe.cn/weather/index', data:{ appkey:localStorage.appkey, token:"0d10e9d06ad1a7106d28841582d6fe1c", doc:"{}" }, success:function(response){ console.log(response); }, error:function(){ console.log(); } }); });
No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access. The response had HTTP status code 400.
这是一个跨域请求数据的Bug,需要加上
dataType: 'jsonp', crossDomain: true,
最后得到的代码是
$.ajax({ type:'POST', url:'http://v.juhe.cn/weather/index', data:{ appkey:localStorage.appkey, token:"0d10e9d06ad1a7106d28841582d6fe1c", doc:"{}" }, dataType: 'jsonp', crossDomain: true, success:function(response){ console.log(response); }, error:function(){ console.log(); }});
我的就解决问题了
