麻烦将变量放入变量

Question

I have many icons, with names icon1, icon2, icon3 and so on... which are coming from server 我有很多图标，它们的名称分别是icon1，icon2，icon3等，它们来自服务器

how can I make a forloop and set that icon NUMBER in a loop automatically?. 如何创建forloop并自动在循环中设置该图标NUMBER ？

I tried this: 我尝试了这个：

{% for i in "1234" %}
  {{icon}}{{forloop.counter}}
{% endfor %}

but this is not giving me what I want. 但这没有给我我想要的东西。 why cannot I do something like this: 为什么我不能做这样的事情：

{{ icon{{forloop.counter}} }},

but this is giving me error, saying it cannot parse the expression 但这给了我错误，说它无法解析表达式

Answer 1

I guess you are looking for concatenation of your icon variable and for loop counter. 我猜您正在寻找icon变量的串联和循环计数器。

{% for i in "1234" %}
 {% with c=forloop.counter|stringformat:"s" %}
  {{icon|add:c}}
 {% endwith %}
{% endfor %}
