我一直关注this，而且我对JavaScript或jQuery的了解非常少。在使用上面的教程开发网站时，我遇到了一个问题，即做出响应式的mob导航。
问题：根据浏览器在启动html文档时的大小，子导航切换不会（它直接转到链接而不是打开子导航菜单）工作如果浏览器是在大约600px的范围内启动的，但是在较小的屏幕尺寸或缩小（有时）时启动。我一直试图弄清楚如何解决这个问题
我的代码（试着保持原状，对不起）：
$(document).ready(function() {
//Creating the show/hide function with jQuery Toggle
$("#navToggle a").on ('click', function(event){
event.preventDefault();
$("header > nav").slideToggle("medium");
$("#logo").toggleClass("menuUp menuDown");
});
//Tidying up the Navigation Menu
$(window).resize(function() {
if($( window ).width() >= "600") {
$("header > nav").css("display", "block");
$("header > nav > ul > li > a").siblings().removeAttr("style");
if($("#logo").attr('class') == "menuDown") {
$("#logo").toggleClass("menuUp menuDown");
}
}
else {
$("header > nav").css("display", "none");
//document.getElementById("categories").href = "categories/index.html";
}
});
//Creating the Drop Down Menu for Mobile Devices
$("header > nav > ul > li > a").click(function(e) {
if($( window ).width() <= "600") {
if($(this).siblings().size() > 0 ) {
event.preventDefault();
$(this).siblings().slideToggle("fast")
$(this).children(".toggle").html($(this).children(".toggle").html() == 'close' ? 'expand' : 'close');
}
}
});

答案 0 :(得分：0)
问题是我的一个愚蠢的疏忽，在我的css中更改断点后，我忘记在我的javascript中更改我的屏幕大小值。为了使javascript工作，valuse必须从600px更改为767px。
对以下javascript的更改。
