获取“未定义XMLHttpRequest”

Question

未定义获取XMLHttpRequest，这是我第一次尝试这种方法。将.open'GET'与APi网址一起使用。

var weatherData;
var request = new XMLHttpRequest();

loadData();

function loadData() {
  request.open('GET', 'https://opentdb.com/api.php?amount=5&category=15&difficulty=easy&type=boolean');
  request.onload = loadComplete;
  request.send();
}

function loadComplete(evt) {
  weatherData = JSON.parse(request.responseText);
  console.log(weatherData);

}

Answer 1

我必须添加此代码段：

 var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
