jquery 来回点击事件

Question

我正在 jquery 与我的工作联系人等一起处理我的作品集。我有 class 隐藏显示 none，我可以点击一个按钮，其他东西隐藏，但我不能在页面之间来回切换。我该怎么做？需要帮助

let startPage = $(".container-startPage");
let about = $(".container-aboutPage");
let portfolio = $(".container-portfolioPage");
let contact = $(".container-contactPage");

$(document).ready(function() {

    $("#about-btn").click(function() {
        about.removeClass("hidden");
        startPage.attr("style", "display:none");
        contact.attr("style", "display:none");
        portfolio.attr("style", "display:none");
    });

    $("#portfolio-btn").click(function() {
        portfolio.removeClass("hidden");
        startPage.attr("style", "display:none");
        about.attr("style", "display:none");
        contact.attr("style", "display:none");
    });

    $("#contact-btn").click(function() {
        contact.removeClass("hidden");
        startPage.attr("style", "display:none");
        about.attr("style", "display:none");
        portfolio.attr("style", "display:none");
    });

});

我不知道 html 代码，但您可以隐藏所有容器兄弟。这是一个例子。希望对你有帮助

let startPage = $(".container-startPage");
let about = $(".container-aboutPage");
let portfolio = $(".container-portfolioPage");
let contact = $(".container-contactPage");

$(document).ready(function() {

    $("#about-btn").click(function() {
        about.removeClass("hidden");
        about.siblings().addClass('hidden')
    });

    $("#portfolio-btn").click(function() {
        portfolio.removeClass("hidden");
        portfolio.siblings().addClass('hidden')
    });

    $("#contact-btn").click(function() {
        contact.removeClass("hidden");
        contact.siblings().addClass('hidden')
    });

});

.hidden {
  display:none;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button id="about-btn">About</button>
<button id="portfolio-btn">Portfolio</button>
<button id="contact-btn">Contact</button>
<div>
  <div class="container-aboutPage ">About Page</div>
  <div class="container-portfolioPage hidden">Portfolio Page</div>
    <div class="container-contactPage hidden">Contact Page</div>
</div>
