【问题描述】:
我正在尝试从 getCurrentPosition 访问经纬度,以便我可以创建一个与 API 一起使用的 URL。如果您从函数内部调用它或者在警报(函数外部)上设置超时,这将起作用,因为当前位置需要一些时间来确定坐标。如何访问坐标变量和/或 URL 之一?谢谢
var coords1;
var coords2;
if (Ti.Geolocation.locationServicesEnabled) {
Titanium.Geolocation.purpose = 'Get Current Location';
Titanium.Geolocation.getCurrentPosition(function(e) {
if (e.error) {
Ti.API.error('Error: ' + e.error);
} else {
coords1 = e.coords.longitude;
coords1 = e.coords.latitude;
}
});
} else {
alert('Please enable location services');
}
var url = "http://www.mywebsite.com/api/return-latlong/"+coords1+"/"+coords2;
var xhr = Ti.Network.createHTTPClient({
onload: function(e) {
// this function is called when data is returned from the server and available for use
// this.responseText holds the raw text return of the message (used for text/JSON)
// this.responseXML holds any returned XML (including SOAP)
// this.responseData holds any returned binary data
Ti.API.debug(this.responseText);
alert('success');
},
onerror: function(e) {
// this function is called when an error occurs, including a timeout
Ti.API.debug(e.error);
alert('error');
},
timeout:5000 // in milliseconds
});
xhr.open("GET", url);
xhr.send(); // request is actually sent with this statement
alert(url);
