Bootstrap 3垂直词缀菜单示例，如文档中的大小调整问题

时间：2013-09-30 16:35:08

标签： javascript twitter-bootstrap twitter-bootstrap-3

我正在尝试使用Bootstrap 3垂直scrollspy，但我找不到源中包含的任何示例。

我继续从这里删除了文档页面http://getbootstrap.com/javascript/但是我在侧边栏中得到了一些非常奇怪的调整大小错误 - 具体来说：

  1. 在页面刷新时，导航栏已定位并正常工作，但在页面调整大小时，它可以从页脚中删除，或在内容结束前消失。

  2. 当刷新并且浏览器视图端口显示页脚（而不是内容）时，侧面导航栏显示在页脚中，而应该停止并与内容的结尾对齐。

    < / LI>

  3. 如果浏览器窗口最大化，则单击导航项不会滚动到相应的标题元素。

    4. 我的问题的视频演示在http://youtu.be/Px5I-wKZ0sA

我迷上了JavaScript一段时间，这就是我想出的：

! function ($) {
    $(function () {
        var $window = $(window)
        var $body = $(document.body)
        var $sideBar = $('.bs-sidebar')
        var navHeight = $('.navbar').outerHeight(true) + 10

        $body.scrollspy({
            target: '.bs-sidebar',
            offset: navHeight
        })

        $('.bs-docs-container [href=#]').click(function (e) {
            e.preventDefault()
        })

        $window.on('resize', function () {
            $body.scrollspy('refresh')
            // We were resized. Check the position of the nav box
            $sideBar.affix('checkPosition')
        })

        $window.on('load', function () {
            $body.scrollspy('refresh')
            $('.bs-top').affix();
            $sideBar.affix({
                offset: {
                    top: function () {
                        var offsetTop = $sideBar.offset().top
                        var sideBarMargin = parseInt($sideBar.children(0).css('margin-top'), 10)
                        var navOuterHeight = $('.bs-docs-nav').height()

                        // We can cache the height of the header (hence the this.top=)
                        // This function will never be called again.
                        return (this.top = offsetTop - navOuterHeight - sideBarMargin);
                    },
                    bottom: function () {
                        // We can't cache the height of the footer, since it could change
                        // when the window is resized. This function will be called every
                        // time the window is scrolled or resized
                        return $('.bs-footer').outerHeight(true)
                    }
                }
            })
            setTimeout(function () {
                // Check the position of the nav box ASAP
                $sideBar.affix('checkPosition')
            }, 10);
            setTimeout(function () {
                // Check it again after a while (required for IE)
                $sideBar.affix('checkPosition')
            }, 100);
        });

        // tooltip demo
        $('.tooltip-demo').tooltip({
            selector: "[data-toggle=tooltip]",
            container: "body"
        })

        $('.tooltip-test').tooltip()
        $('.popover-test').popover()

        $('.bs-docs-navbar').tooltip({
            selector: "a[data-toggle=tooltip]",
            container: ".bs-docs-navbar .nav"
        })
    })
}(window.jQuery)

我认为这与你想要的一样。

关键是让所有的重新计算都在合适的时间进行。重新加载页面时似乎没有检查导航框的位置。每次都需要重新计算页脚的高度，因为页面调整大小时页脚会改变高度。

我还必须玩弄时间。请注意，有两个setTimeout具有不同的延迟，但代码相同。这是为了尽快完成位置检查，但也要等待足够长的IE。

有关详细信息，请参阅代码中的注释。

您正在使用Twitter的文档中的javascript。这些脚本的第一条评论是：

这些脚本仅处理此页面的问题/修复。尝试使用原始的Bootstrap插件解决您的问题，或者根据您的具体情况进行扩展。

我认为你可以通过使用和理解文档中CSS和JavaScript的相关部分来简化这一过程。

最复杂的部分是#sidebar CSS。使用.affix会从页面的典型流程中删除侧边栏，因此您需要为#sidebar设置特定的宽度。 CSS处理侧边栏位置的3个案例（词缀，词缀顶部和词缀底部）。使用了2种不同的媒体查询，因此侧边栏附加内容仅适用于> 992px的较大屏幕，而在> 1200px时稍宽一些..

<强> CSS 

.affix-top,.affix{
    position: static;
}

@media screen and (min-width: 992px) {

  #sidebar .nav > .active > ul {
    display: block;
  }
  #sidebar.affix-top {
    position: static;
    margin-top:30px;
    width:228px;
  }

  #sidebar.affix,
  #sidebar.affix-bottom {
    width: 228px;
  }
  #sidebar.affix {
    position: fixed;
    top: 220px;
  }
  #sidebar.affix-bottom {
    position: absolute;
  }
}
@media screen and (min-width: 1200px) {
  #sidebar.affix-bottom,
  #sidebar.affix {
    width: 235px;
  }
}

另一个重要的部分是javascript，用于计算标题（#masthead） 高于侧边栏的高度，以及 {{1}边栏下面的 。这些高度用于确定footer在顶部变粘的位置，并在页脚在视口中可见时返回底部的绝对位置。

<强>的JavaScript
