我正在编写一个小 JavaScript 来从 JSON 中提取包含名称、经度、纬度和 openweather API 调用的信息。我需要的是从 API 调用中获取 API 信息到 HTML 页面中,这样您就可以获取每个信息的天气预报。我让这两个元素分开工作,但不知道如何让它们一起工作。
请帮忙?:-)
来自 d.weather 的示例 API 天气
api.openweathermap.org/data/2.5/forecase?lat=50.8609&lon=-0.08014&&units=metric
用于拉取 openweather JSON 数据的 HTML 页面
<html>
<head>
<title>Weather</title>
<meta charset="utf-8">
<script src="http://code.jquery.com/jquery-1.7.min.js" ></script>
<script src="http://code.jquery.com/ui/1.7.0/jquery-ui.js" ></script>
<script>
function getWeather(callback) {
var weather = 'http://api.openweathermap.org/data/2.5/forecast?lat=51.5072&lon=0.1275&units=metric';
$.ajax({
dataType: "jsonp",
url: weather,
success: callback
});
}
// get data:
getWeather(function (data) {
console.log('weather data received');
console.log(data.list[0].weather[0].description);
console.log(data.list[0].weather[0].main);
});
getWeather(function (data) {
document.write('weather data received');
document.write('<br>');
document.write(data.list[0].weather[0].description);
document.write('<br>');
document.write(data.list[0].weather[0].main);
document.write('<br>');
document.write(data.list[0].main.temp);
document.write('<br>');
document.write(data.list[0].main[0].dt_txt);
document.write('<br>');
});
</script>
</body>
</html>
用于提取 JSON 数据的 Html 页面
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.0.min.js"></script>
<!-- Javascript -->
<script type="text/javascript">
function loadUrl(newLocation){
window.location = newLocation;
return false;
}
</script>
<script type="text/javascript">
$(document).ready(function (){
$("#btn382").click(function(){
/* set no cache */
$.ajaxSetup({ cache: false });
$.getJSON("weather.json", function(data){
var html = [];
/* loop through array */
$.each(data, function(index, d){
html.push("Team : ", d.Teams, ", ",
"Long : ", d.Long, ", ",
"Lat : ", d.Lat, ", ",
"Weather : ", d.Weather, "<br>");
});
$("#div381").html(html.join('')).css("background-color", "orange");
}).error(function(jqXHR, textStatus, errorThrown){ /* assign handler */
/* alert(jqXHR.responseText) */
alert("error occurred!");
});
});
});
</script>
