溢出滚动不适用于位置固定元素iOS

标签: javascript jquery html css twitter-bootstrap

我在移动设备/尺寸的页面底部有position: fixed导航栏。导航栏本身有一个溢出容器,用户可以向右滚动以查看其他链接(这是一个设计请求,在我看来,用户体验不佳,但那是我的2美分)。

我在iOS设备上测试时遇到的问题是,当顶部/底部本机浏览器元素不在屏幕上时,滚动/任何链接点击都不可用。换句话说,当这些元素自动隐藏时,固定行为根本不起作用。我已经在下面创建了一个小提琴,并且还包含了相关代码的片段,以防万一在iOS上正确查看小提琴的任何问题:

.sticky-nav {
  position: fixed;
  width: 100%;
  bottom: 0;

  border-top: 1px solid #f8f8f8;
  overflow: hidden;
}

.sticky-nav-inner {
  display: -webkit-flex;
  display: flex;

.sticky-nav-menu li {
  display: inline-block;

  margin-right: 25px;
  padding-top: 20px;
}

.sticky-nav-overflow {
  width: calc(100% - 100px);
  height: 100%;
  margin-right: 2%;
  overflow-x: scroll;

我尝试了一些替代方法,例如-webkit-overflow-scrolling没有运气。我觉得这个问题是无关紧要的。似乎甚至没有注册屏幕的那个区域而没有被iOS上的原生底栏向上推。

非常感谢任何和所有的帮助。只是耗尽了我自己尝试的想法。我希望用最少的JavaScript来实现这一目标,但我完全不反对。谢谢你的帮助!

使用溢出时:滚动;属性,-webkit-overflow-scrolling:touch;属性在移动网站上非常有用。它基本上将尴尬的滚动行为改变为正常的预期行为。

     

使用-webkit-overflow-scrolling动态向div添加内容时:touch;超过div的高度,它变得破碎和不可滚动。您可以通过不断设置内部div来解决这个问题,因为它比外部div高1px:

.outer {
  overflow: scroll;
  -webkit-overflow-scrolling: touch;
  /* More properties for a fixed height ... */
}

.inner {
  height: calc(100% + 1px);
}

我没有测试过它。

好吧,我能够解决这个问题(这有点奇怪)。出于某种原因,将导航器固定在最底部似乎是个问题。为了解决这个问题,我使用bottom属性添加了额外的空间,并添加了一个伪元素来填补空白。然后,增加滚动容器内的链接元件的高度。这是更新后的代码:

.sticky-nav {
  position: fixed;
  width: 100%;
  padding-top: 10px;
  bottom: 10px;
  left: 0;
  z-index: 90;
  background-color: #ddd;
  border-top: 1px solid #f8f8f8;
}

.sticky-nav:after {
  content: "";
  position: absolute;
  width: 100%;
  height: 10px;
  bottom: -10px;
  left: 0;
  background-color: #ddd;
}

.sticky-nav-inner {
  display: -webkit-flex;
  display: flex;
  align-items: center;
  justify-content: space-between;
  width: 90%;
  height: 57px;
  max-width: 1200px;
  margin: 0 auto;
  z-index: 0;
}

.sticky-nav-menu {
  display: inline-block;
  white-space: nowrap;
  height: 100%;
  padding-right: 25px;
  margin: 0;
}

.sticky-nav-menu li {
  display: inline-block;
  white-space: nowrap;
  height: 100%;
}

.sticky-nav-menu li a {
  display: inline-block;
  height: 100%;
  padding-top: 20px;
  padding-right: 25px;
}

.sticky-nav-overflow {
  width: calc(100% - 100px);
  height: 100%;
  margin-right: 2%;
  overflow-x: scroll;
}

.sticky-nav-mobile {
  padding-left: 1%;
  z-index: 1;
}

当苹果发布iOS10时,我遇到了同样的问题。你的解决方案就是我所需要的!我的应用程序中的页脚(用流星制作,在带有ios 10的iphone 7上运行)没有粘在底部。但是我能够用更短的版本来解决它。

在我的页脚div上我放了一个position: fixed; and bottom: 0px;的课程 在执行bottom: 0;时,我的页脚位于内容的底部而未修复。

我希望这可以帮助其他人解决同样的问题

在iOS上,浏览器(Safari,Chrome)错误计算在DOM加载后动态添加的内容宽度。例如,在桌面上使用pagination.js并不允许在移动iOS设备上滚动。解决方法是在更改内容后添加此css:

min-height:1000px

这就是我为解决问题所做的工作

尝试检测滚动是否已停止。滚动停止后,然后设置位置:固定在页眉/页脚上。

  var scrollStop = function (callback) {
    // Make sure a valid callback was provided
    if (!callback || Object.prototype.toString.call(callback) !== '[object Function]') return;
    // Setup scrolling variable
    var isScrolling;
    // Listen for scroll events
    window.addEventListener('scroll', function (event) {
        // Clear our timeout throughout the scroll
        $("header").css("position","absolute");
        window.clearTimeout(isScrolling);
        // Set a timeout to run after scrolling ends
        isScrolling = setTimeout(function () {
            // Run the callback
            callback();
        }, 66);
    }, false);
};
// Example
scrollStop(function () {
    $("header").css("position","fixed");
    console.log("Swami scrolling has stopped");
});
