即使没有单击按钮，也会触发click事件(click event fired even if the button has not been clicked)

 您不能将templatetag用作变量，因此： 
 
{% for num in random_num  %}
 
 无法工作。 
 
 您需要将您的模板标签更改为分配标签 
 
@register.assignment_tag
def random_num():
    numbers = range(1,18)
    shuffle(numbers)
    return numbers
 
 ...并使用模板中的as子句： 
 
{% random_num as numlist %}
{% for num in numlist  %}
    {{ num }}
{% endfor %}

You cannot use the templatetag as a variable, so:
 
{% for num in random_num  %}
 
can't work.
 
You need to change your templatetag to an assignment tag
 
@register.assignment_tag
def random_num():
    numbers = range(1,18)
    shuffle(numbers)
    return numbers
 
...and use the as clause in the template:
 
{% random_num as numlist %}
{% for num in numlist  %}
    {{ num }}
{% endfor %}
