後退按鈕無法正常工作

Question

我想關閉窗口後退按鈕，當我第二次按下後退按鈕時。在我的代碼中，我正在運行一個yql查詢並將從查詢獲得的數據插入行中，然後將行添加到表中。我不明白爲什麼我需要按下按鈕2次請幫助。在此先感謝以下是我的代碼：

var DetailWin = Titanium.UI.currentWindow; 
var information = new Array("Company Name: ", "Company Location:", "Position Type:", "Employee   Type:", "Minimum Education:", "Vacancy:", "Gender:", "Salary:"); 
var var1=Ti.App.lurl; 

var rowData = []; 

Titanium.Yahoo.yql('select * from html where url="' + var1 + '" and xpath="//p/span" limit 8',  function(e) { 

    var results = e.data.span; 

    for (var i = 0; i < results.length; i++) { 

     var rss = results[i]; 
     var rssRow = Titanium.UI.createTableViewRow({ 
      top : 200, 
      height : 45, 
      className : 'rssrow' 

     }); 
     var titleLabel = Titanium.UI.createLabel({ 
      text : information[i] + "  " + rss, 
      font : { 
       fontSize : 16, 
       fontWeight : 'bold' 
      }, 
      width : 'auto', 
      top : 5, 
      left : 40, 
      height : 20, 
      color:'black' 
     }); 

     rssRow.add(titleLabel); 

     rowData.push(rssRow); 
    }; 
    jobdetail.setData(rowData); 

}); 

var jobdetail = Titanium.UI.createTableView({ 
    top:'12%', 

}); 

DetailWin.add(jobdetail); 

var backbut = Titanium.UI.createButton({ 
    title:'Back', 
    top:'2%', 
    width:'20%', 
    height:'auto', 
    left:'5%' 
}); 

backbut.addEventListener('click', function(){ 

DetailWin.close(); 

}); 
DetailWin.add(backbut);

您可以通過向窗口添加事件來處理android後退按鈕。

DetailWin.addEventListener('android:back', function(){ 

DetailWin.close(); 

});
