我想知道是否可以像 php 一样向 html div 标签添加 javascript 变量例如：
$id = 1;
<div id="test'.$id.'"></div>
<script>
var id = '1';
</script>
<div id="test..???.??"></div>

Not as simply as that, no. You cando something like:
不是那么简单，不。您可以执行以下操作：
<script>
var id = '1';
</script>
and then later:
然后：
<script>
document.writeln('<div id="' + id + '">');
</script>
...
</div>

Put the <script>code after the divelse it wont find the div
将<script>代码放在divelse之后，它不会找到div

You could use Jquery's .attr() method? Take a look here: http://api.jquery.com/attr/
您可以使用 Jquery 的 .attr() 方法吗？看看这里：http: //api.jquery.com/attr/
var currrentID = $("div").attr("id");
var someInt = 1;
$("div").attr("id", currrentID+someInt);

var divs = document.getElementsByTagName("div"),
newId = 1;
divs[0].setAttribute("id", newId);
