如何在django模板中为标签创建动态标识 [英] How to create dynamic ids for tags in django templates

问题描述

背景：我有一个动态表（因为我不知道它的大小/元素，直到运行时），我试图用javascript函数填充文本区域。要做到这一点，我计划将文本区域的id与我想要的值一起传递到javascript函数中。

问题是我在创建每个文本输入字段的动态id值。这是我目前正在尝试做到这一点：

  {％withinput_| add：applicant.id as idName％ } 
< input id ={{idName}}type =textvalue => 
< input type =buttonhidden =TRUEonclick => 
 {{idName}} 
< script> 
 putTags（{{idName}}，{{tags}}）; 
< / script> 
 {％endwith％} 
  

其中函数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_而没有追加applicant.id的值（并且我已经检查过，applicant.id对于每次迭代都有一个正确的ID）。难道我做错了什么？有没有更简单的方法来创建这些唯一的ID？

解决方案

您可以尝试这样的事情

 < input id =input _ {{applicant.id}}type =textvalue => 
< input type =buttononclick =putTags（'input _ {{applicant.id}}'，{{tags}}）;> 
  

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?

解决方案

You can try something like this

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