鈦手機：所謂的問題JSON解析

Question

朋友你好的onload功能，

我正在開發使用谷歌API地方，所以我使用JSON解析顯示ATM類名單的tableview &地址鈦工作室SDK 1.8.1應用程序使用此link，但getData方法的loader.onload函數不會在json解析中的getData方法的send函數後立即調用，因此它在getDetailsData（）函數之後調用，並且也無法在tableview中顯示地址，所以請給我介紹如何解決這個問題。

在此先感謝。

var lat ,lon ,radius , name , sensor , key , reference, address; 
lat = '-33.8670522';//'23.042067'; 
lon = '151.1957362';//'72.530835';// 
radius = '500'; 
name = title; 
sensor = 'false'; 
key = 'AIzaSyDALrXHC4uMtfSrpCg6NHxqPhsLccLYPZE'; 

var rowData = []; 

// getCategoryData using Google Place API 
function getData() 
{ 
    var loader = Titanium.Network.createHTTPClient(); 

    var url = "https://maps.googleapis.com/maps/api/place/search/json?";  
    url = url + "location=" + lat + ',' + lon; 
    url = url + "&radius=" + radius; 
    url = url + "&name=" + name; 
    url = url + "&sensor=" + sensor; 
    url = url + "&key=" + key; 

    Ti.API.info(url); 
    // Sets the HTTP request method, and the URL to get data from 
    loader.open("GET",url); 
    // Create our HTTP Client and name it "loader" 
    // Runs the function when the data is ready for us to process 
    loader.onload = function() 
    { 
     var obj = JSON.parse(this.responseText); 
     Ti.API.log(obj);  
     var results = obj.results; 
     Ti.API.log(results); 
     for (var i = 0; i < results.length; i++) 
     { 
      var name = obj.results[i].name; 
      reference = obj.results[i].reference; 
      Ti.API.log('Refernce:'+reference); 

        getDetailsData();

function getDetailsData()

    }; 

    // Send the HTTP request 
    loader1.send(); 

    return address; 
} 

getData(); 

Answer 1

Dont't使用在所述第二HTTP請求中返回。 通過函數中的標籤對象，例如：

getDetailsData（addressLabel）;

，並設置內部loader1.onload文本這樣的：

地址= detailsObj.result.formatted_address;

addressLabel.text = address;
