  • jQuery 跨域访问的三种方式 No 'Access-Control-Allow-Origin' header is present on the reque

    问题:

    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:1  
    Resource interpreted as Script but transferred with MIME type text/html: 
    

     解决方案:

    $(function($){  
          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');  
        });
