javascript - 获取 "XMLHttpRequest is not defined"

Question

获取 XMLHttpRequest 未定义，这是我第一次尝试这个东西。使用 .open'GET' 和 APi url。

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

我必须添加这个片段:

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