javascript - 移动子导航不会在一半时间内展开

Question

我一直在关注this到目前为止，我对 JavaScript 或 jQuery 的了解非常少。在使用上述教程制作响应式暴徒导航的网站时，我遇到了问题。

问题: 根据启动我的 html 文档时浏览器的大小，如果浏览器在大约 600px 的范围内启动，但在较小的屏幕尺寸或缩小(有时)时启动时工作。我一直在想办法解决这个问题

我的代码(试着保留它，抱歉，抱歉):

$(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');
            }
        }
    });
    
});

Answer 1

问题是我的一个愚蠢的疏忽，在我更改了我的 css 中的断点之后，我忘记了在我的 javascript 中更改我的屏幕尺寸值。值必须从 600px 更改为 767px 才能使 javascript 正常工作。

以下 javascript 的更改。

$(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() >= "767") {
        $("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() <= "767") {
        if($(this).siblings().size() > 0 ) {
                     event.preventDefault();
            $(this).siblings().slideToggle("fast")
            $(this).children(".toggle").html($(this).children(".toggle").html() == 'close' ? 'expand' : 'close');
        }
    }
});

});
