如何为django模板中的标记创建动态id

Background: I have a dynamic table (as in I don't know its size/elements until runtime) where I am trying to populate a text area with a javascript function. To do this I plan on passing the text area's id along with the values I want to populate it with into the javascript function.

背景:我有一个动态表(在运行时之前我不知道它的大小/元素)，我试图用javascript函数填充一个文本区域。为此，我计划将文本区域的id连同要填充的值一起传递到javascript函数中。

The problem is I am having trouble creating a dynamic id value for each text input field. This is how i am currently attempting to do this:

问题是我在为每个文本输入字段创建动态id值时遇到了麻烦。这就是我目前试图做的:

   {% with "input_"|add:applicant.id as idName %}
        <input id="{{ idName }}" type="text" value="">
        <input type="button" hidden="TRUE" onclick="">
        {{ idName }}
        <script>
            putTags({{ idName }}, {{ tags }});
        </script>
   {% endwith %}

where the function putTags() will populate the text input's contents. Unfortunately this doesn't work, as it assigns everyone's id to "input_" without appending applicant.id's value (and I have checked, applicant.id has a correct id for each iteration). Am i doing something wrong? Is there an easier way to create these unique IDs?

函数putTags()将填充文本输入的内容。不幸的是，这不起作用，因为它将每个人的id分配给“input_”，而不附加申请人。id的值(我查过了，申请人。id对每个迭代都有一个正确的id)。我做错什么了吗?是否有更简单的方法来创建这些唯一的id ?

You can try something like this

你可以试试这个

<input id="input_{{ applicant.id }}" type="text" value="">
<input type="button" onclick="putTags('input_{{ applicant.id }}', {{ tags }});">
