如何从html源代码中删除空格

I am using django and python. In the template file, I have a drop-down list which is shown as below. It works. The only problem is that there is a lot of white space between in the source html code. Is there any way to remove the white space? Thanks.

我正在使用django和python。在模板文件中，我有一个下拉列表，如下所示。它的工作原理。唯一的问题是源html代码之间有很多空白。有没有办法去掉空白?谢谢。

           {% for lang_ele in video.languages.all %}
              {% ifequal lang_ele.lang display_language  %}
                   {% for key, value in language_table.items %}
                       {% ifequal lang_ele.lang key%}
                         <option selected = "selected" value={{lang_ele.lang}}>{{value}}</option>
                       {% endifequal %}
                   {% endfor %}
              {% else %}
                   {% for key, value in language_table.items %}
                       {% ifequal lang_ele.lang key%}
                         <option value={{lang_ele.lang}}>{{value}}</option>
                       {% endifequal %}
                   {% endfor %}

              {% endifequal %}
           {% endfor %}

The output html souce code looks like this:

输出的html souce代码如下:

<option value=de>German</option> 


<option value=el>Greek</option> 


<option value=hi>Hindi</option>

You can use the spaceless template tag. It:

您可以使用无空格模板标记。它:

Removes whitespace between HTML tags.

删除HTML标记之间的空格。

{% spaceless %}
<p>
    <a href="foo/">Foo</a>
</p>
{% endspaceless %}

Look toward middelware, eg "htmlmin". It processes the file at a time. In addition it has a decorator. https://crate.io/packages/django-htmlmin

看看中间的软件，如“htmlmin”。它一次处理文件。此外，它还有一个装饰者。https://crate.io/packages/django-htmlmin
gzip will give the same effect. Probably would have cost to opt out of trimming. Look towards django middelware or nginx gzip.

gzip会产生同样的效果。可能会有成本，选择不削减。看看django middelware或nginx gzip。

You use the controller/model logic in the template. This is wrong way.

在模板中使用控制器/模型逻辑。这是错误的方式。

I used custom helper function with stripping. Here is a an example I used too: http://justcramer.com/2008/12/01/spaceless-html-in-django/

我使用了自定义帮助函数和剥离。这里有一个我也用过的例子:http://justcramer.com/2008/12/01/spaceless-html-in-django/
