从函数外调用位置坐标

我试着从getCurrentPosition访问纬度和长度，以便我可以创build一个URL来使用API​​。 如果从函数内部调用该函数，或者在警报（函数外部）上设置了超时，则当前位置需要花费一些时间来确定坐标。 我如何访问coordsvariables和/或URL？ 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);

不知道我真的得到了你的问题，但是你可以使用一个函数来处理你的api http请求，并且在你获得当前位置的坐标时调用它，如下所示：

 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 { var latitude = e.coords.latitude; var longitude = e.coords.longitude; // make the http request when coords are set apiCall(latitude, longitude); } }); } else { alert('Please enable location services'); } function apiCall(lat, long) { var url = "http://www.mywebsite.com/api/return-latlong/" + lat + "/" + long; alert(url); var xhr = Ti.Network.createHTTPClient({ onload: function(e) { Ti.API.debug(this.responseText); alert('success'); }, onerror: function(e) { Ti.API.debug(e.error); alert('error'); }, timeout:5000 }); xhr.open("GET", url); xhr.send(); }
