XMLHttpRequest cannot load http://v.xxx.com. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:63342' is therefore not allowed access. test.html:1Resource interpreted as Script but transferred with MIME type text/html:

$(function($){      var url = 'http://v.juhe.cn/weather/index';      $.ajax(url, {        data: {          'cityname': '襄阳',          'dtype': 'jsonp',          'key': 'xxxx',          '_': new Date().getTime()        },        dataType: 'jsonp',        crossDomain: true,        success: function(data) {          if(data && data.resultcode == '200'){            console.log(data.result.today);          }        }      });      var url2 = 'http://v.juhe.cn/weather/index?callback=?';      $.getJSON(url2, {        'cityname': '北京',        'dtype': 'jsonp',        'key': 'xxxx',        '_': new Date().getTime()      }, function(data){        if(data && data.resultcode == '200'){          console.log(data.result.today);        }      });      var url3 = 'http://v.juhe.cn/weather/index?callback=?';      $.get(url3, {        'cityname': '澳门',        'dtype': 'jsonp',        'key': 'xxxx',        '_': new Date().getTime()      }, function(data){        if(data && data.resultcode == '200'){          console.log(data.result.today);        }      }, 'json');    });
