I have checkbox that append an item when selected but will not remove it when deselected, just to clarify the appending part is working fine.
the jQuery :
$('.category-checkbox input[type="checkbox"]').click(function (){
if ($(this).is(':checked')) {
// Add the element to the div with an id identifier
$('.items').append('<div id="[{{category.id}}]">123123</div>');
} else {
// Remove the element from the div targeted by the id identifier
$('.items #[{{category.id}}]').remove();
}
});
the template:
<div class="inventory-content">
<div class='category'>
<div>Categories</div>
<div class='category-checkbox'>
{%for category in categories%}
<input type="checkbox" id="{{category.id}}" name="{{category.name}}" value="{{category.id}}">
<label for="{{category.name}}"> {{category.name}}</label><br>
{%endfor%}
</div>
</div>
<div class='items'></div>
</div>
First you would run into problem with duplicated ids, once you did your append. Second jquery don't know what {{category.id}} refers to.
You could do it like:
$('.category-checkbox input[type="checkbox"]').click(function() {
if ($(this).is(':checked')) {
// Add the element to the div with an id identifier
$('.items').append(`<div id="item_${this.id}">123123</div>`);
} else {
// Remove the element from the div targeted by the id identifier
$(`#item_${this.id}`).remove();
}
});
Demo
$('.category-checkbox input[type="checkbox"]').click(function() {
if ($(this).is(':checked')) {
// Add the element to the div with an id identifier
$('.items').append(`<div id="item_${this.id}">123123</div>`);
} else {
// Remove the element from the div targeted by the id identifier
$(`#item_${this.id}`).remove();
}
