Flex mobile - 移至下一页时如何移至 List.selectedItem 中的下一个数据？

发布于 2024-12-04 17:56:06 字数 186 浏览 0 评论 0原文

当我将 page01 移动到 page02 时，我使用以下代码传递相同的数据：

navigator.pushView(Page02, data);

如何移动到 page02 并传递下一行数据（而不是相同的数据）？换句话说，如何用pushView递增到下一行数据？

谢谢。

原文

When I move page01 to page02, I pass the same data along with it using the following code:

navigator.pushView(Page02, data);

How do I move to page02 with passing the next row of data (instead of the same data)?
In other word, how to increment to the next row of data with pushView?

Thanks.

如果您有权访问显示要传递到视图中的数据的 List 组件，则可以执行以下操作：

myList.dataProvider[myList.selectedIndex+1]

您需要进行一些检查以确保您正在尝试引用实际存在的索引：

var mySelectedObject :Object;
if(myList.selectedIndex+1 < myList.dataProvider.length){
    mySelectedObject = myList.dataProvider[myList.selectedIndex+1] 
} else {
    // do some other behaviour; such as selecting the first one in the list
    mySelectedObject = myList.dataProvider[0] 
}
navigator.pushView(page02, mySelectedObject );

If you have access to the List component which displays the data you want to pass into views, you can do something like this:

myList.dataProvider[myList.selectedIndex+1]

You'll want to do some checking to make sure that you're trying to reference an index that actually exists:

var mySelectedObject :Object;
if(myList.selectedIndex+1 < myList.dataProvider.length){
    mySelectedObject = myList.dataProvider[myList.selectedIndex+1] 
} else {
    // do some other behaviour; such as selecting the first one in the list
    mySelectedObject = myList.dataProvider[0] 
}
navigator.pushView(page02, mySelectedObject );
