I have a select:

<select class="form-control">
    <option value="0" selected>Selecione uma opção</option>
    <option value="1">1</option>
    <option value="2">2</option>
    <option value="3">3</option>
    <option value="4">4</option>
    <option value="5">5</option>
    <option value="6">6</option>
    <option value="7">7</option>
</select>

And just below, mixed, I have the following code on Python:

{% for objeto in objetos %}
    {% if objeto.escolha == 'opcao do select' %}
        FAÇA ISSO
    {% else %}
        FAÇA AQUILO
    {% endif %}
{% endfor %}

How do I save the selected value in select to be used in if of the code Python?

html python

  • I believe that you wanted to take the value of select and make a change to the page, but python renders the page and sends it to the client machine, and only by making a new request could it take this value and then do some action, I believe that the best way to solve your problem is by making the change using javascript

The template engine is not used to manipulate the DOM in real time. In this case, Javascript is used.

HTML:

<select class="form-control" id="select1" onchange="handleSelectChange()">
    <option value="0" selected>Selecione uma opção</option>
    <option value="1">1</option>
    <option value="2">2</option>
    <option value="3">3</option>
    <option value="4">4</option>
    <option value="5">5</option>
    <option value="6">6</option>
    <option value="7">7</option>
</select>

<h1 id="text1"></h1>

JS:

var select = document.getElementById('select1');
var h1 = document.getElementById('text1');

function handleSelectChange(v)
{
    if(select.value == 1)
        h1.innerHTML = 'Selecionou a opção' + select.value.toString();
    else
        h1.innerHTML = 'Selecionou uma opção diferente de 1';

}

Nowadays, probably, no one uses pure javascript like I did above, recommend jQuery or a modern js framework like Vue.js and the like.

EDIT 1:

Remembering that all manipulation done via JS is on the front end, if you want to interact with the back end (Django I imagine), you can use Ajax.
