我应该使用 Ajax 和 JSON 创建一个带有 Weather Underground API 的应用程序,但实际上并没有太多关于如何去做的指导。如果我能看到代码的完整版本,那么我就知道应该如何开始。我就是这样学习的。我对 JSON 了解一点,但我不确定下一步是什么。

这是我的代码:

<!DOCTYPE html>
<!--Your Name
Date
Month
-->
<html>
<head>
<title>Weather API App</title>

<link href="style.css" rel="stylesheet" type="text/css">
</head>

<body>

<div id="container">
<header>
<img class="logo" src="http://icons.wxug.com/logos/PNG/wundergroundLogo_4c_horz.png" alt="logo"/>
<h1>Your Awesome Forecast Page</h1>
<nav>
<ul>
<li><a href="#">Weather</a></li>
<li><a href="#">Conditions</a></li>
<li><a href="#">Forecasts</a></li>
<li><a href="#">Contact</a></li>
</ul>
</nav>
</header>
<div class="conditions">
<h2>Current Conditions</h2>
<div class="window1">

<!-- 1. Display the icon for the current conditions (observation)

3. Display temperature in Ferinheiths
4. Display feels like temperature

-->
</p>
</div>
<div class="hourly">
<h2>Your Hourly 1-day forecast</h2>
<p>
<!-- 1. Display the Hourly 1-day forecast
2. Display the condition for each hour
3. Display the temperature for each hour
-->
</p>
</div>
<div class="7_day">
<h2>Your 7-day forecast</h2>
<p>
<!-- 1. Display the 7-day forecast

padding: 2%;
}

main.js

$.ajax({
url : "http://api.wunderground.com/api/ef5a156e62f050d2/conditions/q/OH/Columbus.json",
dataType : "json",
success : function(url) {
var location = url['location']['city'];
var temp_f = url['current_observation']['temp_f'];
$(".conditions").html("Current temperature in " + location + " is: " + temp_f+"ºF");
}
});

最佳答案

这是让您开始的一个开始。您的 AJAX 函数返回 JSON 数据(打开控制台并查看)。对于 temp_f,从 JSON 数据检索任何特定键/值的正确方法如下所示。然后,正如您已经完成的那样,根据从 JSON 中提取的各种元素构建一个字符串,并将其写入您选择的 HTML 元素:

$.ajax({
url: "http://api.wunderground.com/api/ef5a156e62f050d2/conditions/q/OH/Columbus.json",
dataType: "json",
success: function(url) {
console.log(url);
var location = 'Columbus';
var temp_f = url.current_observation.temp_f;
$(".conditions").html("Current temperature in " + location + " is: " + temp_f + "ºF");
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="conditions"></div>
