使用 Django For 循环将下拉选择传递给模态答案

【问题标题】：Passing Dropdown Choice to Modal Using Django For Loop使用 Django For 循环将下拉选择传递给模态
【发布时间】：2021-08-28 01:47:26
【问题描述】：

我有一个带有选项的下拉菜单。下拉菜单应链接到我想说“您选择了选项 A”（或 B 或 C）的模式，具体取决于单击的内容。

我尝试了data-target="#myModal{{choice}}" 和id="myModal{{choice}}"，希望它们能被链接，但这样一来，模态框根本不会出现。

当我删除 {{choice}} 时会出现模式，但这不是我想要的。

感谢阅读。非常感谢您的帮助。

views.py：

def modal_home(request):
    choices = [
        "A",
        "B",
        "C"
    ]

    return render(request, 'modal/test-modal.html', {
        'choices': choices,
    })

test-modal.html:

【问题讨论】：

你需要做另一个循环并为每个choices创建一个.modal
@ArleighHix 是的，用另一个循环包裹模态 div 是可行的。非常感谢

【解决方案1】：

您需要执行另一个循环并为每个choices 创建一个.modal。

    <div class="dropdown">
        <button class="btn dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown">
            Create
        </button>
        <div class="dropdown-menu">
            {% for choice in choices %}
                <a class="dropdown-item" href="#" data-toggle="modal" data-target="#myModal{{choice}}">{{ choice }}</a>
            {% endfor %}
        </div>
    </div>

  {% for choice in choices %}

    <div class="modal fade" id="myModal{{choice}}" tabindex="-1" role="dialog">
        <div class="modal-dialog" role="document">
        <div class="modal-content">
            <div class="modal-header">
            <h5 class="modal-title" id="exampleModalLabel">MODAL</h5>
            <button type="button" class="close" data-dismiss="modal">
            </button>
            </div>
                <p>You selected Choice {{ choice }}</p>
            </div>
        </div>
    </div>   

  {% endfor %}
