嗨，你错过了一个封闭的报价：

Answer 2

First of all, there's the missing quote, as @erognaut and @unenthusiasticuser have pointed out.

As far as I know, I don't think it's possible to inject JS variables into HTML like you're trying to do there. It is possible with PHP or a server-side language, though.

Or, like @jBot-42 said, you may want to change the id using JS or jQuery using a script, but not like that. For example:

<input type="button" data-id='array_elem' />

<script>
    var array = ['hi','by','miao'];
    // uses jQuery
    $("input[data-id='array_elem']").attr("id", array[1]);
</script>
