如何遍历数据中的数组：AJAX调用

I have an array of courses. I'm using Rapid API for the back-end. I want to loop through the array and equate if "course": [one of those elements in the array].

我有一系列的课程。我正在使用Rapid API作为后端。我想循环遍历数组并等于“course”:[数组中的其中一个元素]。

sendEmail.js

var courses = ["course1", "course2", "course3", "course4"];
var courseLoop;
var dayLoop;
jQuery.ajax({
url: "http://something-something.rapidapi.io/get-day",
type: "POST",
contentType: "application/x-www-form-urlencoded",
data: {
  "course":for(i=0;i<4;i++){
    courseLoop = courses[i];
    if("course" == courseLoop){
      alert("found");
      break;
    }
},
"day": "1",
},
})
.done(function(data, textStatus, jqXHR) {
alert("HTTP Request Succeeded: " + jqXHR.status);
console.log(data);
})
.fail(function(jqXHR, textStatus, errorThrown) {
alert("HTTP Request Failed");
})
.always(function() {
/* ... */
});

I know I'm way off, but this is where I've got till.

我知道我已经离开了,但这是我要到的地方。

To evaluate if specific value present in your array or not you could use anonymous IIFE(Wiki). It will be something like this:

要评估数组中是否存在特定值,您可以使用匿名IIFE(Wiki)。它将是这样的:

var courses = ["course1", "course2", "course3", "course4"];
var courseLoop;
var dayLoop;
jQuery.ajax({
    url: "/echo/json/",
    type: "POST",
    contentType: "application/x-www-form-urlencoded",
    data: {
      "course": (function(courses, courseLoop) {
        //in jquery you can use inArray
        for (var i = 0; i < 4; i++) {
          if ("course" === courses[i]) {
            courseLoop = courses[i];
            //alert("found");//Removing Blocking Call
            if (window.console && console.log) console.log('found');
            break;
          }
        }
        return courseLoop;
      }(courses, courseLoop)), //Douglas Crockford's style
      "day": "1"
    }
  })
  .done(function(data, textStatus, jqXHR) {
    //alert("HTTP Request Succeeded: " + jqXHR.status);
    if (window.console && console.log) console.log(data, textStatus, jqXHR, jqXHR.status);
  })
  .fail(function(jqXHR, textStatus, errorThrown) {
    //alert("HTTP Request Failed");
    if (window.console && console.log) console.log(jqXHR, textStatus, errorThrown);
  })
  .always(function() {

  });

The way to loop through arrays is basically

循环遍历数组的方法基本上就是这样

.done(function(data, textStatus, jqXHR) { data.each(function(item) { if (item.courseTitle == 'blah') { console.log(item); } }); console.log(data); })

.done(function(data,textStatus,jqXHR){data.each(function(item){if(item.courseTitle =='blah'){console.log(item);}}); console.log(data) ;})
