Forecast.io API 与 jQuery 的使用 [英] Forecast.io API Usage with jQuery
问题描述
我在使用 API(特别是 Forecast.io 天气 API)创建完整的应用程序时遇到了一些问题.为简单起见，我将我的 JS 直接放在我的 HTML 页面中.对于这个基本版本，我很高兴能有这个节目.假设我想要当前温度(当前 -> 温度).另外，我不确定?回调?"始终推荐用于所有 RESTful API.
I'm having some trouble creating a complete application using an API, specifically the Forecast.io weather api. For simplicity, I've put my JS directly in my HTML page. For this basic version, I would be happy just to have this show something. Let's say I wanted current temperature (currently -> temperature). Also, I'm not sure if "?callback?" is always recommended for all RESTful APIs.
<!DOCTYPE html>
<html>
<body>
<p id="weather">Here's the weather:<p>
<button onclick="b()">Submit</button>
<script>
function b(){
var apiKey = '<private>';
var url = 'https://api.forecast.io/forecast/';
var lati = 0;
var longi = 0;
var data;
$.getJSON(url + apiKey + "/" + lati + "," + longi + "?callback=?", function(data) {
$('#weather').innerHTML('and the weather is: ' + data[4].temperature);
});
}
</script>
</body>
</html>
推荐答案
你犯的主要错误是没有包含 jQuery :-)下一个是在 jQuery 对象上，您需要使用 html() 函数而不是 JavaScript 原生的 innerHTML 属性.
The main mistake you made is not including jQuery :-) The next one is that on a jQuery object you need to use the html() function instead of the JavaScript native innerHTML property.
如果你使用console.log(data)你可以看到返回对象的所有属性，所以你可以像data.currently.temperature一样正确引用它
If you use console.log(data) you can see all the properties of the returned object, so you can reference it correctly like data.currently.temperature
<!DOCTYPE html>
<html>
<body>
<p id="weather">Here's the weather:<p>
<button onclick="b()">Submit</button>
<script>
function b(){
var apiKey = '<PRIVATE>';
var url = 'https://api.forecast.io/forecast/';
var lati = 0;
var longi = 0;
var data;
$.getJSON(url + apiKey + "/" + lati + "," + longi + "?callback=?", function(data) {
//console.log(data);
$('#weather').html('and the temperature is: ' + data.currently.temperature);
});
}
</script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
</body>
</html>
