Javascript Django：如何创建一个在用户单击时更改的动态表单？

我正在制作一个训练日历网站，用户可以在其中添加不同提升量、设置和重复次数等的训练。因此，我需要一个表单，在用户单击按钮时添加一个字段。我制作了一个模板和一些javascript来描述我想要实现的目标：

网址：

url（r'^add/（？P[0-9]+）/（？P[0-9]+）/（？P[0-9]+）/$），views.add_锻炼，name='add_锻炼'）

模板：

{% block hidden %}
{% include "workoutcal/liftrow.html" %} {# To be used by Javascript #}
{% include "workoutcal/cardiorow.html" %}
{% endblock %}

<form action="{% url 'add_workout' date.year date.month date.day %}" method="post">

    <div class="row">
        <div class="col-xs-2">
            <p id="date">{{ date.year }}-{{ date.month }}-{{ date.day }}</p>
            <input type="hidden" name="date" value="{{ date }}">
        </div>
    </div>

    <h2 class="col-xs-12">Lifts</h2>
    <div id="liftrows">
        {% for i in range %}
          {% include "workoutcal/liftrow.html" %}
        {% endblock %}
    </div>

    <div class="row">
        <div class="col-xs-0"></div>
        <label class="col-xs-2"><button type="button" id="addliftbutton">One more lift</button></label>
    </div>



    <h2 class="col-xs-12">Cardio</h2>

    <div id="cardiorows">
        {% include "workoutcal/cardiorow.html" %}
    </div>

    <div class="row">
        <label class="col-xs-2"><button type="button" id="addcardiobutton">One more cardio</button></label>
    </div>
    <div class="row">
        <div class="col-xs-10"></div>
        <label class="col-xs-2"><input type="submit" id="submitbutton" value="Save Workout"></label>
    </div>
</form>

{%block hidden%}
{%include“workoutcal/liftrow.html”%}{{#由Javascript使用#}
{%include“workoutcal/cardiorow.html”%}
{%endblock%}
{{date.year}-{{date.month}-{{date.day}
提起
{范围%中的i的%1}
{%include“workoutcal/liftrow.html”%}
{%endblock%}
再来一次
有氧运动
{%include“workoutcal/cardiorow.html”%}
再来一次有氧运动

javascript:

//Adding onclick to buttons
document.getElementById('addliftbutton').onclick = addLiftRow;
document.getElementById('addcardiobutton').onclick = addCardioRow;

for (var i=0; i<setsBoxes.length; i++){
    setsBox = setsBoxes[i];
    setsBox.onchange = insertRepFields;
}

function addLiftRow(){
    var liftRowElements = document.getElementById('liftrows');

    var hidden_liftrow = document.getElementById('hidden').getElementsByClassName('lift')[0];
    var new_liftrow = hidden_liftrow.cloneNode(true);

    liftRowElements.appendChild(new_liftrow);
}

function addCardioRow(){
    var cardiorows = document.getElementById('cardiorows');

    var hidden_cardiorow = document.getElementById('hidden').getElementsByClassName('cardio')[0];
    var new_cardiorow = hidden_cardiorow.cloneNode(true);

    cardiorows.appendChild(new_cardiorow);
}

function insertRepFields(){} // big function that inserts as many input fields as the number inside the box whose event called the function.

//将onclick添加到按钮
document.getElementById（'addliftbutton'）。onclick=addLiftRow；
document.getElementById（'addcardiobutton'）。onclick=addCardioRow；
对于（var i=0；i实现这一点的最佳方法是插入具有相同名称的输入，然后在Django中以列表形式获取所有这些输入，如：

def view(request):
    inputs = request.POST.getlist('your_input_name')
    for i in inputs:
        Model.objects.create() # Save your model

谢谢你的回答。你说的“插入同名输入”是什么意思？@Sandi当你通过POST方法发送输入时，你用属性名
标识输入，这样在后端你就可以将其作为字典获取，如果有多个输入，你将收到一个列表
def view(request):
    inputs = request.POST.getlist('your_input_name')
    for i in inputs:
        Model.objects.create() # Save your model
