Jquery switch class on click event

Question

I have the folowing example:

<div class="filtrer">
    <a class="bold">Url 1</a>
    <a>Url 2</a>
</div>

First url is active, second is inactive, bold means is selected. I should be allowed to press only on Url 2, and as soon as i do that, the bold class shoud switch to the Url 2.

What i already tryed and did not work was this:

$('.filtrer a').filter(':not(.bold)').on('click', function(){
    var current = $('.filtrer a').filter(':not(.bold)');
    var standby = $('.filtrer a.bold');

    current.addClass('bold');
    standby.removeClass('bold');
})

Does anybody know why this is not working? Or have an optimized solution? Thanks

Answer 1

You are dealing with dynamic element selectors, so you need to use delegation based event handlers

var $as = $('.filter a');
$('.filter').on('click', 'a:not(.bold)', function () {
    var current = $as.filter(':not(.bold)');
    var standby = $as.filter('.bold');

    current.addClass('bold');
    standby.removeClass('bold');
})

It can be written as

var $as = $('.filter a');
$('.filter').on('click', 'a:not(.bold)', function () {
    $as.toggleClass('bold');
})

Answer 2

$('.filter').on('click','a:not(.bold)',function(){
  $(this).siblings().add(this).toggleClass('bold');
});

Or without jQuery:

<div class="filter">
  <input type="radio" name="url" id="url1"><label for="url1">url1</label>
  <input type="radio" name="url" id="url2"><label for="url2">url2</label>
</div>

.filter input[type=radio]{
  display:none;
}
.filter input[type=radio]:checked + label{
  font-weight:bold;
}

Answer 3

您拼错了“过滤器”，请在代码或HTML中对其进行更改。

Answer 4

$('.filtrer').on('click',' a:not(.bold)', function(){    
    $('.filtrer a.bold').removeClass('bold');;
    $(this).addClass('bold');    
})

Answer 5

Something like :

$('.filter a').click(function() {
    $('.filter a').removeClass('bold');
    $(this).addClass('bold');
});
