Bootstrap 3 vertical affix menu example as in the docs - resizing issue

Question

Bootstrap 3 vertical affix menu example as in the docs - resizing issue

g18*_*18c 9 javascript twitter-bootstrap twitter-bootstrap-3

I am trying to use Bootstrap 3 vertical scrollspy, however I cannot find any examples included in the source.

I went ahead and stripped out the documentation pages from here http://getbootstrap.com/javascript/ but I am getting some very strange resize bugs with the sidebar - specifically:

On page refresh the nav bar is positioned and works OK, but on page resize it can drop off past the footer, or disapear before the end of the content.
When refreshed and the browser view port shows the footer (and not the content), the side nav bar shows in the footer whereas is should stop and be aligned with the end of the content.
If the browser window is maximized, clicking on the navigation items does not scroll to the corresponding header element.

我和JavaScript搞砸了一段时间,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"
        })

我认为这表现得像你想要的.

关键是要在正确的时间进行所有重新计算.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.

有关更多详细信息,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:

// 注意!!不要使用任何这样的JAVASCRIPT //这对我们的DOC来说都是JUNK!// +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

这些脚本仅处理此页面的问题/修复.尝试使用原始Bootstrap插件修复问题,或者根据具体情况扩展它们.

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将从页面的典型流程中删除侧边栏,因此您需要为其设置特定的宽度#sidebar.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,因此侧边栏固定仅适用于> 992px的较大屏幕,而在> 1200px时稍宽一些.

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;
  }
}

其他重要的部分是,其计算标题的高度的JavaScript (#masthead) 边栏以上,并且边栏下方.这些高度用于确定在顶部将变为粘性的位置,并在页脚在视口中可见时返回到底部的绝对位置.footer affix

JavaScript的

$('#sidebar').affix({
      offset: {
        top: function () {
          var navOuterHeight = $('#masthead').height();
          return this.top = navOuterHeight;
        },
        bottom: function () {
          return (this.bottom = $('footer').outerHeight(true))
        }
      }
});
