javascript - Canvas 外菜单和固定位置的标题

Question

我正在创建一个非常基本的非 Canvas 菜单，一切都运行良好，但我无法解决这个小问题!

1. 访问www.loaistudio.com并将窗口大小调整到 1000 像素以下。
2. 稍微向下滚动，然后点击标题左上角的“菜单”按钮。

为什么会绝望？它实际上并没有绝望，但它只是移动到页面的最顶部!这是为什么？我该如何修复它并将其保持在 View 区域的顶部...

这是HTML

            <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>

JavaScript:

        a.preventDefault();

    //Smart Navigation
    $(".secondHeader-menuButton").on('touchstart click',  function(e) {
        e.preventDefault();
        $("#page").toggleClass("pageOpen");
        $("#headerWrapper").toggleClass("headerOpen");
        $(this).toggleClass("secondHeader-menuButton-active");
    });

    $('.content').on('touchstart click', function() {
        $("#page").removeClass("pageOpen");
        $('#headerWrapper').removeClass('headerOpen');
        $('.secondHeader-menuButton').removeClass("secondHeader-menuButton-active");
    });

}); 

Answer 1

尝试将您的#headerWrapper 转换更改为:

-moz-transition: -moz-transform 0.2s ease-out;
-o-transition: -o-transform 0.2s ease-out;
-webkit-transition: -webkit-transform 0.2s ease-out;
transition: transform 0.2s ease-out

至于标题在翻译后变得“不固定”:这似乎是一个 known bug in Webkit .

您可以通过以下方式修复它:

1) 将#secondHeader 移到#page 之外:

    <body>
      <header id="headerWrapper"></header>
      <div id="secondHeader"></div>
      <div id="page"></div>
    </body>

2) 添加一个新的 CSS 类:

    #page.pageOpen, #secondHeader.pageOpen {
        -webkit-transform: translate(200px, 0px);
        -moz-transform: translate(200px, 0px);
        -o-transform: translate(200px, 0px);
        -ms-transform: translate(200px, 0px);
        transform: translate(200px, 0px);  
    }

3) 添加过渡到#secondHeader

    #secondHeader {
      -moz-transition: -moz-transform 0.2s ease-out;
      -o-transition: -o-transform 0.2s ease-out;
      -webkit-transition: -webkit-transform 0.2s ease-out;
      transition: transform 0.2s ease-out
    }

4) 也通过 Javascript 切换这个类:

$(".secondHeader-menuButton").on('touchstart click',  function(e) {
    e.preventDefault();
    $("#page, #secondHeader").toggleClass("pageOpen");
    $("#headerWrapper").toggleClass("headerOpen");
    $(this).toggleClass("secondHeader-menuButton-active");
});

$('.content').on('touchstart click', function() {
    $("#page, #secondHeader").removeClass("pageOpen");
    $('#headerWrapper').removeClass('headerOpen');
    $('.secondHeader-menuButton').removeClass("secondHeader-menuButton-active");
});
