How can I remove a class to all element which are not a child of

Time:09-14

I am following a css flex video and I am trying to build a menu with several levels. I am using jQuery to open and close a menu and sub-menu, and sub-sub-menu, etc.

Here is my demo.

  1. I click on "Contact"
  2. Then, I clik on "A propo" and "Contact" should close.
  3. I click on the first sub-menu (Item 1.2) => The first level should not close
  4. I click on the second sub-menu (Item 1.2.3) => All of this direct ul parent, should not close.
  5. Then now, when I click again to "Contact", all menu and sub-menus of "A propos" should close

My problem, I do not know how to target the first level of li.hasChildren and check all of child of other ul li.hasChildren and look for the children to close the opened menu and sub-menu.

Here is my script to close/open the selected menu, which works

( function( $ ) {

    $( '.dropdown-toggle' ).click( function( e ) {
        var _this = $( this );
        e.preventDefault();
        _this.toggleClass( 'toggled-on' );
        _this.find('.fa').toggleClass( 'fa-angle-down fa-angle-up');
        _this.parent().next( '.sub-menu' ).toggleClass( 'toggled-on' );
        _this.attr( 'aria-expanded', _this.attr( 'aria-expanded' ) === 'false' ? 'true' : 'false' );

         // HOW CAN I CHECK ALL OTHER MENUS
        
    } );

})( jQuery );

Above, I created a variable _this

  1. How can I check for the first li.hasChildren from _this
  2. Then how can check if there is other parent li.hasChildren up to the first level of li
  3. Then how can check all other branch of the tree to close the ul-su-menu bellow li.hasChildren, excepted for the tree that the click come from

I tried with parentUntil()

(this).parentsUntil("li.hasChildren").css( "background-color", "red" );

to mark with a class first level, but I apparently jQuery stop at the first li.hasChildren it meet, and do not continue until the first level

Note, when a menu or sub-menu is open, the ul take the class ul.toggled-on. To close a sub-menu, we can use removeClass('.toggled-on')

here is my html code

 <nav  role="navigation" aria-label="Main navigation">

        <li >
            <div>

Then my question is, how can I check all ul.toggled-on, which does not belong of the branch where I clicked

Many thanks

CodePudding user response:

I finally found a solution as the following

( function( $ ) {

    $( '.dropdown-toggle' ).click( function( e ) {
        e.preventDefault();
        
        //console.log( e   ": "   $( this ).siblings('a').text() );

        // Add or remove the toggled-on class and change the aria-expand status of the link
        $(this).toggleClass('toggled-on').attr('aria-expanded',$(this).attr('aria-expanded') === 'false' ? 'true' : 'false')
        .find('.fa').toggleClass('fa-angle-down fa-angle-up')
        // find the closest parent div and go to the first ul.sub-menu, then add/remove the class toggled-on to the ué
        .closest('div').eq(0).next('ul').toggleClass('toggled-on')
        // Go up to the closest hasChildren class and look at all system/brother of .hasChildren
        .closest('.hasChildren').eq(0).siblings(".hasChildren")
        // Find .dropdown-toggle and do a forwach for all of them
        .find('.dropdown-toggle').each(function(){
            $('#breadcrumb').text('');
            //$(this).css("background-color", "blue");
            // remove the toggled-on class and change the axia-expanded status of each links
            $(this).removeClass('toggled-on').attr('aria-expanded','false')
            // change the icon
            .find('.fa').removeClass('fa-angle-up').addClass('fa-angle-down')
            // move up to the closest div and go to the next ul (ul.sub-menu) and remove the toggled-on class to close the menu
            .closest('div').eq(0).next('ul').removeClass('toggled-on');
        });

        $('#breadcrumb').append(' / '   $( this ).siblings('a').text());

    } );

})( jQuery );

I hope, you will like it

CodePudding user response:

You can set a class active for the last click on your menus.

Like this, you can do a loop with each() and check for unactive menu.

I commented my code.

( function( $ ) {

    $( '.dropdown-toggle' ).click( function( e ) {
        $( '.dropdown-toggle' ).removeClass('active');
        
        var _this = $( this );
        e.preventDefault();
        _this.toggleClass( 'toggled-on' );
        _this.find('.fa').toggleClass( 'fa-angle-down fa-angle-up');
        _this.parent().next( '.sub-menu' ).toggleClass( 'toggled-on' );
        _this.attr( 'aria-expanded', _this.attr( 'aria-expanded' ) === 'false' ? 'true' : 'false' );
        _this.addClass( 'active' );

        // check if link has submenu
        var checkIfSubMenu = _this.parent('div:first').nextAll('ul.sub-menu:first');
        //console.log(checkIfSubMenu.length);
  
        // check for inactive toogled menu
        var checkIfNotActiveSubMenu = $( 'a.toggled-on:not(.active)' );
        //console.log(checkIfNotActiveSubMenu.length);
        
        // close inactive menu
        $('.toggled-on').each(function() {
          // we get the link in the previous div and check if the link dont have class active 
          if (!$(this).prevAll('div:first').find('.dropdown-toggle').hasClass('active')) {
            // so we remove class for the submenu
            $(this).removeClass('toggled-on');
          }
        });

        // HOW CAN I CHECK ALL OTHER MENUS
        
    } );
    
    $( '.e-panel ul li div a:not(.dropdown-toggle, .link)' ).click( function( e ) {
      $('.toggled-on').removeClass('toggled-on');
    });
})( jQuery );
