function PostHandle(url,data,callback) {
        $.ajax({
            type: "Post",
            url:url,
            data:data,
            dataType:'json',
            async: false,
            success: callback
        });
    }

var arr = new Array(); //arr是你想要传递的数组，自己定义即可

 PostHandle("/getOriginalGrade",{ "arr":JSON.stringify(arr)},function(result){
                console.log(result)
            });

str:= this.GetString("arr")
