(1)for...in循环中的迭代变量是对象中的属性,键值对中的键值
var mockData:Object={ID: 1,Say:"Hello",Name:"yuxuanji"}; for (var entry:Object in mockData) { trace(entry); }
console output:
ID
Say
Name
//结论:for 遍历的是key
(2)for each...in循环中的迭代变量是对象键值对中保存的值(属性所保存的值)
for each (var entry:Object in mockData) { trace(entry); }
console output:
123
Hello
yuxuanji
//结论:for each遍历的是value
