我最近启动了一个基于我为我的投资组合网站创建的虚拟公司的项目。我遇到的问题实现了一段jQuery代码来切换一个名为hidden的类，它将设置类的展示位置为none。我正在使用此类在某些媒体查询断点处切换移动导航。但是，隐藏的toggleClass不起作用。你们能帮助你们吗？ 这里是我的地盘： https://jorgeg1105.github.io/JG-Photography/JQuery toggleClass问题没有按预期工作
//When the page loads, Fade in all divs with class hidden.
//Then Remove hidden class.
$(document).ready(function() {
$('div.hidden').fadeIn(2000).removeClass('hidden');
});
//Fade In all h3 with class hidden.
//Remove hidden class.
$('h3.hidden').fadeIn(3000).removeClass('hidden');
//Image Filter
$(document).ready(function() {
\t $("#mainnav ul li a").click(function(){
\t \t var category = $(this).attr("class");
\t \t if (category == "all"){
\t \t \t $("#imgcontainer img").addClass("hidden");
\t \t \t setTimeout(function(){
\t \t \t \t $("#imgcontainer img").removeClass("hidden");
\t \t \t });
\t \t }
\t \t else {
\t \t \t $("#imgcontainer img").addClass("hidden");
\t \t \t setTimeout(function(){
\t \t \t \t $("."+category).removeClass("hidden");
\t \t \t });
\t \t }
\t });
});
//When burger is clicked. Mobile nav and mainnav are toggled.
$(".burger").on("click", function(){
\t $("#mainnav").toggleClass("hidden");
\t $(".mobilenav").toggleClass("hidden");

将具体宽度添加到''li''style =“width：150px; text-align：center;”'这样闪烁就可以被删除了.. –
@Champ Decay我不明白。我在600 px断点处宽度为100％，我的文本垂直对齐，但这与jQuery有什么关系？ – Jorge
