为什么我的ajax请求报这个错误

Question

jquery.js:8630 XMLHttpRequest cannot load file:///C:/Users/Yaphets/Desktop/text/data.json?callback=jQuery214005026997282902079_1493192403330&_=1493192403331. Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.


 $.ajax({                type:"GET",
                url:"data.json",
                dataType:"jsonp",
                success:function(data){
                  alert(data)
                },
            });

如果想模拟本地的JSON数据 需要部署一个服务器，如apache之类的哦，你这个ajax 还涉及到跨域，建议在真实环境下实验，或者暂时不跨域 先传json 这种就行了
