如何将值从 django html 发送到 django 视图

Question

I want to make a section with goods in which you can "+" and "-" increase or decrease the quantity of goods And then, depending on the amount, "sell" it.

Now we need to pass the value {{ el.id }} to django views

My code: html:

    <form method="POST">
    {% csrf_token %}
    {% for el in form3 %}
    {% if el.count > 0 %}
           [ {{ el.count }}шт. ] <br>
           [ {{ el.title }} ]<br>
           <a id="minus{{ el.id }}" href="#"><b>[ - ]</b></a>
           <span id="value{{ el.id }}">0</span>
            <a id="plus{{ el.id }}" href="#"><b>[ + ]</b></a>
            <br>
Function where i + or - from count
<script>
$(function(){
    var valueElement = $('#value{{ el.id }}');
    function incrementValue(e){
        valueElement.text(Math.max(parseInt(valueElement.text()) + e.data.increment, 0));
        return false;

    }
    $('#plus{{ el.id }}').bind('click', {increment: 1}, incrementValue);
    $('#minus{{ el.id }}').bind('click', {increment: -1}, incrementValue);
});
</script>
            {% endif %}
            {% endfor %}
       </form>

how can i get the values with "span id=value{{ el.id }}"

Solved

    {% for el in form3 %}
    {% if el.count > 0 %}
           [ {{ el.count }}шт. ] <br>
           [ {{ el.title }} ]<br>
           <a id="minus{{ el.id }}" href="#"><b>[ - ]</b></a>
           <span id="span-value{{el.id}}">0</span>
           <a id="plus{{ el.id }}" href="#"><b>[ + ]</b></a>
        <br>
                <input type="hidden" name=name-{{el.id}} id="input-{{el.id}}" value="0">
        <script>
            $(function(){
            var valueElement = $('#span-value{{el.id}}');
            function incrementValue(e){
            valueElement.text(Math.max(parseInt(valueElement.text()) + e.data.increment, 0));
    var value = $("#span-value{{el.id}}").text();
    var lower=$("#input-{{el.id}}").val(value);
            return false;
            }
                $('#plus{{ el.id }}').bind('click', {increment: 1}, incrementValue);
                $('#minus{{ el.id }}').bind('click', {increment: -1}, incrementValue);
            });
        </script>
    {% endif %}
    {% endfor %}

use this for copy\\duplicate span value on input After this you can user request.post.dict or request.post.items() for key:values
