How to create dynamic ids for tags in django templates

问题

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.

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:

   {% 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?

回答1:

You can try something like this

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