Javascript Question

Javascript onclick menu button show sidebar, onmouseleave hide sidebar

I have a sidebar which is hidden by default and a menu button which trigger the sidebar. So far, everything is working but what I want is, when I click on the menu, the sidebar gets opened and on mouse leave, the sidebar gets closed.

I have checked other solutions and tried to implement it in my code but its not working.

Here are my html and js

//html
<div id="wrapper">

<!-- sidebar content -->

<!-- Menu button -->
<div id="page-content-wrapper">
<button type="button" class="hamburger is-closed" data-toggle="offcanvas">
<span class="hamb-top"></span>
<span class="hamb-middle"></span>
<span class="hamb-bottom"></span>
</button>
</div>
</div>


//js
<script type="text/javascript">
$(document).ready(function () {
var trigger = $('.hamburger'),
overlay = $('.overlay'),
isClosed = false;

trigger.click(function () {
hamburger_cross();
});

function hamburger_cross() {

if (isClosed == true) {
overlay.hide();
trigger.removeClass('is-open');
trigger.addClass('is-closed');
isClosed = false;
} else {
overlay.show();
trigger.removeClass('is-closed');
trigger.addClass('is-open');
isClosed = true;
}
}

$('[data-toggle="offcanvas"]').click(function () {
$('#wrapper').toggleClass('toggled');
});
});
</script>


Thanks

Answer

In order to close the menu on mouseleave you may write:

$('.navbar').on('mouseleave', function (e) {
   trigger.click(); // simulate the action you now do to close the menu
})

$(document).ready(function () {
  var trigger = $('.hamburger'),
      overlay = $('.overlay'),
      isClosed = false;

  trigger.click(function () {
    hamburger_cross();
  });
  $('.navbar').on('mouseleave', function (e) {
    trigger.click();
  })

  function hamburger_cross() {

    if (isClosed == true) {
      overlay.hide();
      trigger.removeClass('is-open');
      trigger.addClass('is-closed');
      isClosed = false;
    } else {
      overlay.show();
      trigger.removeClass('is-closed');
      trigger.addClass('is-open');
      isClosed = true;
    }
  }

  $('[data-toggle="offcanvas"]').click(function () {
    $('#wrapper').toggleClass('toggled');
  });
});
