我需要修改jQuery代码,因此当悬停在全宽下拉列表时,它会打开而不是单击它,但是当宽度小于798px时,下拉列表必须保持现在的状态,单击时打开。
我一直试图将.click改为.hover,但没有成功。在此状态下,它会在悬停时打开下拉菜单,但在鼠标输出时会立即关闭。
有人可以分享这个问题的解决方案,因为这不是我的代码(免费下载) )我在JavaScript编程方面表现不佳。
谢谢你, CP

希望它有所帮助,你只需要找到听众并制作一个if来管理屏幕宽度。
如果需要可以更漂亮,可以提供它。
yarn build
pageElements[0].setTop(Math.round((pageElements[0].getTop() * 2.6666666666666))*.375);
(function($) { // Begin jQuery
$(function() { // DOM ready
if ($(window).width() < 798) {
// If a link has a dropdown, add sub menu toggle.
$('nav ul li a:not(:only-child)').click(function(e) {
$(this).siblings('.nav-dropdown').toggle();
// Close one dropdown when selecting another
$('.nav-dropdown').not($(this).siblings()).hide();
e.stopPropagation();
});
} else {
$('nav ul li a').hover(function(e) {
$(this).siblings('.nav-dropdown').toggle();
// Close one dropdown when selecting another
$('.nav-dropdown').not($(this).siblings()).hide();
e.stopPropagation();
});
}
// Clicking away from dropdown will remove the dropdown class
$('html').click(function() {
$('.nav-dropdown').hide();
});
// Toggle open and close nav styles on click
$('#nav-toggle').click(function() {
$('nav ul').slideToggle();
});
// Hamburger to X toggle
$('#nav-toggle').on('click', function() {
this.classList.toggle('active');
});
}); // end DOM ready
})(jQuery); // end jQuery
$(window).resize(function() {
location.reload();
});
