geoLocationに基づいてJSONを返すweather API呼び出しに問題があります。ブラウザは、質問に場所へのアクセスの許可/拒否を依頼し、API呼び出しを、ページロード時に実行したいとします。代わりにボタンクリックの後ろにコールを入れましたが、それでも地元の天気のページは更新されません。しかし、デバッガを使用してコードをステップ実行すれば、正しく動作します。ユーザーがアクセスを許可した後にブラウザGeoLocationを使用する方法
Javascriptを:
$(document).ready(function() {
var curLatitude = 'x';
var curLongditude = 'y';
var weatherApi = 'http://api.openweathermap.org/data/2.5/weather?q=London,GB&APPID=[insert-registered-api-key]';
// check for Geolocation support
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
curLatitude = position.coords.latitude;
curLongditude = position.coords.longitude;
if (curLatitude !== 'x' && curLongditude !== 'y') {
weatherApi = 'http://api.openweathermap.org/data/2.5/weather?lat=' + curLatitude +
'&lon=' + curLongditude + '&APPID=[insert-registered-api-key]';
};
loadWeather(weatherApi);
}, function() {
console.log('FAILED');
});
} else {
console.log('No geoLoc');
// no geo location support - just load London weather
loadWeather(weatherApi);
};
$('#btnLocal').click(function() {
$(".message").html('clicked');
loadWeather(weatherApi);
});
function loadWeather(weatherApiUri) {
var current = "";
var ok;
var ret = $.getJSON(weatherApiUri, function(jsonres) {
console.log("JSON Data: loaded");
current = 'called api';
console.log(current);
$(".message").html(current);
}).done(function() {
console.log("done");
}).fail(function() {
console.log("error");
}).always(function() {
console.log("complete");
});
var weatherReturned = {id:0 , main:"weather", description:"weather detail", icon:"code" };
weatherReturned = ret.responseJSON.weather;
$(".message").html(ret.responseJSON.name + ', ' + weatherReturned[0].description);
};
});
