在php中,如果您有以下代码:

$map = array(
  "first" => 1,
  "second" => 2
);

$map["third"] = 3;

foreach($map as $key => $value) {
  // code
}

您知道条目将按照它们添加到阵列的顺序列出.

现在,我可以假设同样的规则适用于下面的Javascript等价物吗？

map = {
  "first": 1,
  "second": 2
};

map["third"] = 3;

for (key in map) {
  // code
}

这是一个副本:元素顺序 - 在javascript中的(... in ...)循环

好的,所以在网页上,我有一个JavaScript对象,我用它作为一个关联数组.当页面加载时,这在脚本块中静态存在:

var salesWeeks = {
    "200911" : ["11 / 2009", "Fiscal 2009"],
    "200910" : ["10 / 2009", "Fiscal 2009"],
    "200909" : ["09 / 2009", "Fiscal 2009"],
    "200908" : ["08 / 2009", "Fiscal 2009"],
    "200907" : ["07 / 2009", "Fiscal 2009"],
    "200906" : ["06 / 2009", "Fiscal 2009"],
    "200905" : ["05 / 2009", "Fiscal 2009"],
    "200904" : ["04 / 2009", "Fiscal 2009"],
    "200903" : ["03 / 2009", "Fiscal 2009"],
    "200902" : ["02 / 2009", "Fiscal 2009"],
    "200901" : ["01 / 2009", …
