无法从Titanium Appcelerator中的OptionDialog框中选择选项？

Question

我在Titanium中创建了一个OptionDialog.我已从动态数组中添加了这些选项列表.如何在单击对话框中的任何项目时获取特定选项值？

var View = Ti.UI.createTextField({
height : '60dp',
width : '90%',
value : 'click here'
)};

myArray = ['Lion','Tiger','Cat','Elephant','Dog'];

var opts = {
  cancel: 2,
  options: myArray,
  selectedIndex: 2,
  destructive: 0,
};

var dialog;
View.addEventListener('click',function(){
    dialog = Ti.UI.createOptionDialog(opts).show();
});

我尝试过如下,但不起作用.

dialog.addEventListener('click',function(e){
    alert('You Clicked' + e.source.options);
});

更改您的代码如下

var myArray = ['Lion','Tiger','Cat','Elephant','Dog'];

var opts = {
  cancel: 2,
  options: myArray,
  selectedIndex: 2,
  destructive: 0,
};

var dialog;
View.addEventListener('click',function(){
    dialog = Ti.UI.createOptionDialog(opts);
    dialog.show();
    dialog.addEventListener('click', onSelectDialog);
});

function onSelectDialog(event){
    var selectedIndex = event.source.selectedIndex;
    //OR
    //var selectedIndex = dialog.selectedIndex();
    alert('You have selected' + myArray[selectedIndex ]);
}
