flex 3 遍历对象值 [英] flex 3 iterate through object values

问题描述

我有一个代表数据库表的对象.我想遍历这个对象并打印每个值.我可以用什么来做到这一点?

i have an object which represents a database table. I want to iterate through this object and print printing each value. What can i use to do this?

我想在我的 mxml 而不是 actionscript 中执行此操作

i want to do this inside my mxml not actionscript

为每个对象属性我想创建一个输入字段

for each object attribute i want to create an imput field

推荐答案

查看有关 Flex 3 循环的文档.如果你这样做，你会发现:

Look up the documentation on Flex 3 looping. If you do, you'll find this:

for..in

for..in 循环遍历对象的属性或数组的元素.例如，您可以使用 for..in 循环来遍历通用对象的属性(对象属性不按任何特定顺序保存，因此属性可能以看似随机的顺序出现):

The for..in loop iterates through the properties of an object, or the elements of an array. For example, you can use a for..in loop to iterate through the properties of a generic object (object properties are not kept in any particular order, so properties may appear in a seemingly random order):

var myObj:Object = {x:20, y:30};
for (var i:String in myObj)
{
    trace(i + ": " + myObj[i]);
}
// output:
// x: 20
// y: 30

建议您不要尝试为每个对象创建输入字段，而是查看 DataGrid 和自定义 ItemEditors.

Instead of trying to create an input field for each object, I'd suggest you take a look at DataGrid and custom ItemEditors.
