对于每个循环，除了Firefox之外，并不适用于主流浏览器 [英] for each loop is not working in major browsers except firefox

问题描述

我的代码：

<script type="text/javascript">
for each ( var movie in ['Endhiran The Robot','Shivaji The Boss','Anbulla Rajinikanth'] )
    document.writeln(movies + "<br/>");
</script>

在Firefox中，我将输出作为

In Firefox, I am getting the output as

Endhiran The Robot
Shivaji The Boss
Anbulla Rajinikanth

但在 IE9 和 Chrome版本23.0.1271.95 m 中，对于每个都不起作用，文档上也没有写入任何内容

But in IE9 and Chrome Version 23.0.1271.95 m, for each is not working and nothing is written on the document

推荐答案

$ c>对于JavaScript中的每个，这是一个非标准的扩展。

There is no for each in JavaScript, that was a non-standard extension.

有新的 ES5 forEach function ，这在现代浏览器中得到了很好的支持，尽管当然不是老版本：
$ b

There is the new ES5 forEach function, which is well supported in modern browsers although of course not in older ones:

['Endhiran The Robot','Shivaji The Boss','Anbulla Rajinikanth'].forEach(function(movie) {
    document.writeln(movie + "<br/>");
});

这个其他答案在这里堆栈溢出。 （这个问题提到了jQuery，但答案涵盖了普通的JavaScript和jQuery选项。）

Several other options over in this other answer here on Stack Overflow. (The question mentions jQuery, but the answer covers both plain JavaScript and jQuery options.)
