我有一个包含以下代码的code.html文件.

 $.ajax({ 
                    type: "POST", 
                    datatype: "JSONP",
                    url: "path",
                    success: function(msg){
                    var e = document.createElement("div");
                    e.id = "ads";
                    document.body.appendChild(e);
                    $("#ads").html(msg);

                    }
           });

当我在浏览器中打开code.html文件时,它会出错:

**"XMLHttpRequest cannot load file://..... Origin null is not allowed by Access-Control-Allow-Origin."**

请帮我!!如何避免这个问题
