flex3 - flex 3 遍历对象值

Question

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

我想在我的 mxml 中执行此操作而不是 actionscript

对于每个对象属性，我想创建一个输入字段

Answer 1

查找有关 Flex 3 循环的文档。如果你这样做了，你会发现:

for..in

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

与其尝试为每个对象创建一个输入字段，我建议您查看 DataGrid和定制 ItemEditors .
