如何影响 django for 循环中的单个条目? [英] How can I affect individual entries in a django for loop?

问题描述

我在 Django 中创建了一个 for 循环，用于显示用户上传的文章.对于长文章，我会将文本截断为最大长度为 150 个字符，但希望让读者可以选择使用 jquery 函数扩展文本，方法是单击阅读更多".这是我的模板:

I have created a for loop in Django which displays articles uploaded by users. In the case of long articles I will truncate the text to a max length of 150 chars, but want to give readers the option of expanding the text using a jquery function, by clicking 'read more'. This is my template:

{% for post in posts %}
    {% if post.content|length > 150 %}
        <p class="half-content">{{ post.content|truncatechars:150 }}<a href="javascript:void();" class="show-hide-btn">read more</a></p>
        <p class="full-content" style="display: none;">{{ post.content }}</p>
    {% else %}
        <p>{{ post.content }}</p>
    {% endif %}
{% endfor %}

这是我的 jquery 函数:

And here is my jquery function:

$(document).ready(function(){
    $(".show-hide-btn").click(function(){
        $(".half-content").hide();
    });
});
$(document).ready(function(){
    $(".show-hide-btn").click(function(){
        $(".full-content").show();
    });
});

它按我的意愿工作，除了阅读更多"链接扩展页面上的所有文章，而不仅仅是具有适当主键的文章.我知道我需要在代码中的某处包含 {{ post.id }}，但到目前为止我尝试过的所有方法都无效.

It works how I would like it to, except that the 'read more' link is expanding all the articles on the page, not just the one with the appropriate primary key. I know I need to include {{ post.id }} in my code somewhere, but so far everything I have tried has been ineffective.

推荐答案

试试这个，

{% for post in posts %}
    {% if post.content|length > 150 %}
        <p class="half-content" id="half-{{post.id}}">{{ post.content|truncatechars:150 }}<a data-id="{{post.id}}" href="javascript:void();" class="show-hide-btn">read more</a></p>
        <p class="full-content" id="full-{{post.id}}" style="display: none;">{{ post.content }}</p></div>
    {% else %}
        <p>{{ post.content }}</p>
    {% endif %}
{% endfor %}


<script>
    $(document).ready(function(){
        $(".show-hide-btn").click(function(){
            var id = $(this).data("id");
            $("#half-"+id).hide();
            $("#full-"+id).show();
        });
    });
</script>
