Check all the checkboxes by clicking one button
So the example html is like below:
<button type="button" id='check_all'>Check All</button>`
<input type="checkbox" name="vehicle" value="Bike">I have a bike<br>
<input type="checkbox" name="vehicle" value="Car">I have a car
<input type="checkbox" name="vehicle" value="Motorbike">I have a Motorbike We can check or uncheck them all using:
$('#check_all').click(function() {
$('input[name=vehicle]').prop('checked', true);
});
$('#check_all').click(function() {
$('input[name=vehicle]').prop('checked', false);

Here's more universal version:
/**
* Un/Select multiple checkboxes using one checkbox
* @param {jQuery selector} $list List of checkboxes
* @return {object}
*/
$.fn.checkboxMaster = function(list) {
return this.on('click', function() {
$(list).prop('checked', $(this).prop('checked'));
});
}Usage:
$('#check_all').checkboxMaster('input[name=vehicle]');
@idered That's a pretty neat function, but my example uses a radio button instead of a checkbox. How can I modify your function to suit the example? I tried to set checked property on the button in the html <button type="button" id='check_all' checked>Check All</button>, but it did not work. I then tried to use jQuery to set it $('#check_all').prop('checked', true);which actually works, but it wont achieve the same effect as your original function, because clicking the button won't change the checked property from true to false. So any suggestions?
@idered workaroud seems to work with any control that contains 'Checked' property.
@tmaster, @felipekm How about this?
$.fn.checkboxMaster = function(list) {
return this.on('click', function() {
var isChecked = $(list).first().prop('checked');
$(list).prop('checked', ! isChecked );
});
