What i am trying to do is to show the total from each selected checkbox for example. if i select a checkbox with the value 100 and than select another with the value 200 i get 300 as output and if i deselect it it will go off the totaal i tried everything i could but no result at all need some help in this.
This is above the html I use PHP so i can change the values quicker
<?php
//basisprijs en titel die erbij komen, Dit moet aangepast worden.
$basisPrijs=
array(
array("titel" => 'template1', "prijs" => '100'),
array("titel" => 'template2', "prijs" => '200'),
array("titel" => 'template3', "prijs" => '300'),
array("titel" => 'template4', "prijs" => '400')
);
//onderdelen en titel die erbij komen, Dit moet aangepast worden.
$onderdelen=
array(
array("titel" => 'Table', "prijs" => '100'),
array("titel" => 'Checkbox', "prijs" => '200'),
array("titel" => 'List', "prijs" => '300'),
array("titel" => 'Selectbox', "prijs" => '400')
);
$titel="Bereken tool";
$check="Bestellen";
?>
And this goes after the head and Jquery
<body>
<!-- <script type="text/javascript"></script> -->
<div class="container">
<div id="content">
<h3><?php echo $titel; ?></h3>
<form action="index.php" method="post">
<div class="checkbox">
<?php foreach($onderdelen as $key => $value)
{echo "<div class='checkbox'>
<label><input class='check' type='checkbox' value='".$onderdelen[$key]["prijs"]."'
name='".$onderdelen[$key]["titel"]."'>"
.$onderdelen[$key]["titel"]."</label></div>"
;}?>
</div>
</form>
<div>
<button type="button" class="btn btn-default"><?php echo $check; ?></button>
<p id="output">output:</p>
</div>
</div>
</div>
<script>
$(document).ready(function()
{
$(".check").change(function()
{
var prijs= this.checked ? this.value : '';
$("#output").text(prijs);
});
});
</script>
</body>
