天气应用程序Javascript无法工作

Weather app Javascript isn't working

本文关键字：工作 Javascript 应用程序      更新时间：2023-09-26

控制台什么都没有。它应该将html的包含内容更改为从openweatherapp获取的此邮政编码的信息(我检查此zip，它存在并且函数updateByZip创建良好的链接)。第一个代码是JS，第二个是HTML。JS 

var temp;
var loc;
var humidity;
var icon;
function bg() {
  var backs = ["http://wallpapercave.com/wp/JthAGYd.jpg", "http://www.desktopwallpaperhd.net/wallpapers/20/b/welshdragon-landscapes-cometh-background-204971.jpg", "http://s1.picswalls.com/wallpapers/2014/08/08/scottish-landscape-desktop-backgrounds_015751372_152.jpg", "http://img.wallpaperfolder.com/f/4313075B95B2/amazing-winter-backgrounds-6770538-landscape.jpg"];
  var ran = Math.floor(Math.random() * (backs.length));
  $('body').css("background-image", "url('" + backs[ran] + "')")
    //document.body.style.background = "url/'('" + backs[0] + "') no-repeat";
}
function tempCF() {
  var x = document.getElementById("temp").innerHTML;
  var y = document.getElementById("CF").innerHTML;
  x = parseInt(x);
  if (y == "C") {
    x = Math.floor((9 / 5 * x + 32));
    document.getElementById("temp").innerHTML = x;
    document.getElementById("CF").innerHTML = "F"
  } else if (y == "F") {
    x = Math.floor((x - 32) * 5 / 9);
    document.getElementById("temp").innerHTML = x;
    document.getElementById("CF").innerHTML = "C";
  };
}
function updateByZip(zip) {
  var APPID = "55e568aa04114cdf3dc4b90c9ae0a60c";
  var url = "api.openweathermap.org/data/2.5/weather?zip=" + zip + "&APPID=" + APPID;
  sendRequest(url);
}
function sendRequest(url) {
  var xmlhttp = new XMLHttpRequest();
  xmlhttp.onreadystatechange = function() {
    if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
      var data = JSON.parse(xmlhttp.responseText);
      var weather = {};
      weather.temp = data.main.temp;
      weather.humidity = data.main.pressure;
      weather.loc = data.name;
      //weather.icon = data.weather[0].id;
      update(weather);
    }
  };
  xmlhttp.open("GET", url, true);
  xmlhttp.send();
}
function update(weather) {
  document.getElementById("temp").innerHTML = weather.temp;
  document.getElementById("humidity").innerHTML = weather.humidity;
  document.getElementById("loc").innerHTML = weather.loc;
  //document.getElementById("icon").innerHTML = weather.icon;  
};
window.onload = function() {
  var temp = document.getElementById("temp").innerHTML;
  var loc = document.getElementById("loc").innerHTML;
  var humidity = document.getElementById("humidity").innerHTML;
  //var icon = document.getElementById("icon").innerHTML;
  updateByZip(94040);
  //weather.icon = "https://cdn1.iconfinder.com/data/icons/hawcons/32/700175-icon-1-cloud-128.png";
};

    </div>

</body>

您的API url不正确。你应该写:

var url = "http://api.openweathermap.org/data/2.5/weather?zip=" + zip + "&APPID=" + APPID;
