Java JTwig For循环使用范围而不是容器

Question

I want to be able to do the equivalent of the following loop using a JTwig template: 我希望能够使用JTwig模板执行以下循环的等效操作：

for (int i = 0; i < length; i++ ) { ... }

I have tried the following but neither seem to work: 我尝试了以下但似乎都没有工作：

{% set k = 10 %}
{% for i in 1..k %}
    <option value={{k}} >{{k}}</option>
{% endfor %}

Or 要么

{% set k = 10 %}
{% for i in range(1,k) %}
    <option value={{k}} >{{k}}</option>
{% endfor %}

I can loop containers but can't seem to find a way of getting this kind of thing to work. 我可以循环容器，但似乎无法找到让这种东西工作的方法。

Answer 1

You have to add square brackets, like so: 你必须添加方括号，如下所示：

{% for i in [1..10] %}
    {{ i }}
{% endfor %}

I discovered this rather by accident. 我偶然发现了这一点。 It seems to be missing from the documentation. 它似乎从文档中遗漏了。
