菜单打开时禁用滚动体

Question

My menu in wordpress has the following code:

<nav role='navigation'>
    <div id="menuToggle" onclick="lockScroll()" >
        <input type="checkbox"  />
        <span></span>
        <span></span>
        <span></span>
        <ul id="menu">
            <?php
            wp_nav_menu( array(
                'theme_location' => 'menu-1',
            ) );
        ?>
        </ul>
    </div>
</nav>

And this jQuery function to disable scroll in body when #menuToggle is clicked:

<script>
    jQuery(function(lockScroll) {
        if ($('body').hasClass('lock-scroll')) {
            $('body').removeClass('lock-scroll');
        }
        else {
            $('body').addClass('lock-scroll');
        }
  });
</script>

But it always gives me the error

Uncaught TypeError: $ is not a function at HTMLDocument.

Answer 1

Please Try This:-

jQuery(function(lockScroll) {
        if (jQuery('body').hasClass('lock-scroll')) {
            jQuery('body').removeClass('lock-scroll');
        }
        else {
            jQuery('body').addClass('lock-scroll');
        }
  });

Im not exactly sure what 'open' means in your case. This code should most likely do the right thing or push you in the right direction:

jQuery( '#menuToggle' ).click( function() {

    jQuery( 'body' ).addClass( 'lock-scroll' );

} );

jQuery( document ).on( 'mousedown', function( e ) {

    var c = jQuery('#menuToggle');

    if( !c.is( e.target ) && c.has( e.target ).length === 0 ) {

        jQuery( 'body' ).removeClass( 'lock-scroll' );

    }


} );

If you click #menuToggle the lock-scroll class is added (first part). As soon as you click outside of #menuToggle it will be removed (second part).

This way a can disable the scroll when click

<script>
    jQuery('#menuToggle').click( function(){

    jQuery( 'body' ).addClass( 'lock-scroll' );
        });

    </script>

How can i remove class when click again?
