通过AS3字典高效循环

Question

for (var k in dictionary) 
{
  var key:KeyType = KeyType(k);
  var value:ValType = ValType(dictionary[k]); // <-- lookup
  // do stuff
}

这是我用来遍历字典中的条目.正如您在每次迭代中看到的那样,我在字典中执行查找.是否有更有效的方法来迭代字典(同时保持对密钥的访问)？

Answer 1

通过键和值迭代:

for (var k:Object in dictionary) {
    var value:ValType = dictionary[k];
    var key:KeyType = k;
}

更简洁地迭代值:

for each (var value:ValType in dictionary) {

}
