>我正在使用天气API。 我想将纬度和经度从地理位置页面传递到 API,以便它获取当前天气。 有没有任何选择来实现这一点。请帮忙。您的帮助将不胜感激。 这是我的JS代码:
function SearchLocation(e) {
var searchLocationInput = {
query: 'Chennai',
format: 'JSON',
timezone: 'yes',
popular: '',
num_of_results: '',
callback: 'SearchLocationCallback'
};
JSONP_SearchLocation(searchLocationInput);
e.preventDefault();
}
function SearchLocationCallback(searchLocation) {
output = "<br/> Area Name: " + locationSearch.search_API.result[0].areaName[0].value;
output += "<br/> Country: " + locationSearch.search_API.result[0].country[0].value;
output += "<br/> Latitude: " + locationSearch.search_API.result[0].latitude;
output += "<br/> Longitude: " + locationSearch.search_API.result[0].longitude;
output += "<br/> Population: " + locationSearch.search_API.result[0].population;
output += "<br/> Region: " + locationSearch.search_API.result[0].region[0].value;
resultContainer.empty();
resultContainer.html(output);
}
这是我的地理位置代码:
<html>
<head>
<title>Getting Geolocation for Weather Details</title>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta charset="UTF-8">
<style type="text/css">

}
#map_canvas {

}
@media print {
html, body {

}
#map_canvas {
height: 650px;
}
}
</style>
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?sensor=true"></script>
<script type="text/javascript">
var map;
function initialize() {
var myOptions = {
zoom: 16,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map_canvas'),
myOptions);
// Try HTML5 geolocation
if(navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
var pos = new google.maps.LatLng(position.coords.latitude,
position.coords.longitude);
var infowindow = new google.maps.InfoWindow({
map: map,
position: pos,
content: '<a href="weatherdetails.html">click here for weather details</a>'
});
map.setCenter(pos);
}, function() {
handleNoGeolocation(true);
});
} else {
// Browser doesn't support Geolocation
handleNoGeolocation(false);
}
}
function handleNoGeolocation(errorFlag) {
if (errorFlag) {
var content = 'Error: The Geolocation service failed.';
} else {
var content = 'Error: Your browser doesn't support geolocation.';
}
var options = {
map: map,
position: new google.maps.LatLng(60, 105),
content: content
};
var infowindow = new google.maps.InfoWindow(options);
map.setCenter(options.position);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="map_canvas"></div>
</body>
</html>
此 API 有据可查,传递纬度和经度,通过 q
-参数用逗号分隔。
简单的实现:
if(navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
$.getJSON('http://api.worldweatheronline.com/free/v1/weather.ashx?callback=?',
{format:'json',
key:'yourKey',
q:[position.coords.latitude, position.coords.longitude].join(',')
},
function(r){
alert(r.data.current_condition[0].weatherDesc[0].value);
})
});
}
