I have this code that is possible to check/uncheck all checkboxes and check/uncheck a single checkbox.
<!DOCTYPE HTML>
<html>
<head>
<meta charset=utf-8>
<title>Persist checkboxes</title>
</head>
<body>
<div>
<label for=checkAll>Check all</label>
<input type=checkbox id=checkAll>
</div>
<div>
<label for=option1>Option 1</label>
<input type=checkbox id=option1>
</div>
<div>
<label for=option2>Option 2</label>
<input type=checkbox id=option2>
</div>
<div>
<label for=option3>Option 3</label>
<input type=checkbox id=option3>
</div>
<script src=http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js></script>
<script src=http://cdn.jsdelivr.net/jquery.cookie/1.4.0/jquery.cookie.min.js></script>
<script>
$(#checkAll).on(change, function() {
$(':checkbox').not(this).prop('checked', this.checked);
});
$(:checkbox).on(change, function(){
var checkboxValues = {};
$(:checkbox).each(function(){
checkboxValues[this.id] = this.checked;
});
$.cookie('checkboxValues', checkboxValues, { expires: 7, path: '/' })
});
function repopulateCheckboxes(){
var checkboxValues = $.cookie('checkboxValues');
if(checkboxValues){
Object.keys(checkboxValues).forEach(function(element) {
var checked = checkboxValues[element];
$(# + element).prop('checked', checked);
});
}
}
$.cookie.json = true;
repopulateCheckboxes();
</script>
My question is that I want to make a button that will have a function that will clear or uncheck all checkboxes. Could some help me do that? Thanks!
