我是前端 Web 开发新手，但我过去做过很多 JavaScript，但我真的不知道为什么这段代码，我在这上面浪费了很多时间，我需要完成这个很快。

它根本不会执行，但我看不到语法错误或它是如何错误的(它主要基于SO答案，因为我不知道jQuery)，我需要帮助声明和使用jQuery函数，或者如果它是AJAX 调用错误

Answer 1

您构建网址的方式错误

url: "http://localhost:2000/mapReduce/getMapReduceResultsTopPickRate?day="day,

需要

url: "http://localhost:2000/mapReduce/getMapReduceResultsTopPickRate?day=" + day,

最好使用数据

$.ajax({
  url: "http://localhost:2000/mapReduce/getMapReduceResultsTopPickRate",
  data : {
      day : day
  },
  type: "get",
  dataType: 'json',
  success: function(data){
        alert("got it"); // debug
        showTopPickrate(data);
  },
  error:function(){
      alert("error");
  }  
});
