Question

我正在使用Bootstrap的3.2.0 Off Canvas布局位于 - http://getbootstrap.com/examples/offcanvas/

我知道这是一个常见问题，如果侧边栏的内容比主容器的内容长，滚动条不再正确滚动内容（侧边栏和主要内容），但会切断侧边栏并放置边框导航栏下方的滚动条。

我可以通过采用上述模板并在侧边栏中添加额外链接同时在主容器中放入较少内容来重现此问题，例如：

<div class="container">

    <div class="row row-offcanvas row-offcanvas-right">

        <div class="col-xs-12 col-sm-9">
            <p class="pull-right visible-xs">
                <button type="button" class="btn btn-primary btn-xs" data-toggle="offcanvas">Toggle nav</button>
            </p>
            <div class="jumbotron">
                <h1>Hello, world!</h1>
                <p>This is an example to show the potential of an offcanvas layout pattern in Bootstrap. Try some responsive-range viewport sizes to see it in action.</p>
            </div>
            <div class="row">
                <div class="col-12 col-sm-12 col-lg-12">
                    <h2>Heading</h2>
                    <p>Donec id elit non mi porta gravida at eget metus. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus. Etiam porta sem malesuada magna mollis euismod. Donec sed odio dui. </p>
                    <p><a class="btn btn-default" href="#" role="button">View details &raquo;</a></p>
                </div><!--/span-->
            </div><!--/row-->

无论主要内容有多长，无论如何都能可靠地让侧边栏工作？

Answer 1

快速修复offcanvas.j：

jQuery('[data-toggle=offcanvas]').click(function () {

// add this line to change the position of sidebar
jQuery('.row-offcanvas').hasClass( "active" ) ? jQuery('.sidebar-offcanvas').css("position","absolute") :        jQuery('.sidebar-offcanvas').css("position","relative");  
// end modif      

jQuery('.row-offcanvas').toggleClass('active')
});

Answer 2

我遇到了这个确切的问题。在尝试了许多变通方法之后，我发现删除double overflow-x对我有效。

所以只需从：

中删除body或html

html,
body {
  overflow-x: hidden; /* Prevent scroll on narrow devices */
}

我宁愿保持身体。

Answer 3

以下是我们必须遵循的HTML结构： -

            <div class="container">

                <div class="row row-offcanvas row-offcanvas-left">

                    <div class="col-xs-6 col-sm-3 sidebar-offcanvas" id="sidebar" role="navigation">
                        <ul>
                            <li class="active"><a href="#">Home</a></li>
                            <li><a href="#">Link 1</a></li>
                            <li><a href="#">Link 2</a></li>
                            <li><a href="#">Link 3</a></li>
                          </ul>
                    </div>

                    <div class="col-xs-12 col-sm-9 content-div">
                        <p class="pull-left hide-p visible-xs">
                    <button type="button" class="btn btn-primary btn-sm" data-toggle="offcanvas">Toggle nav</button>
                  </p>
                    </div>
                </div>
            </div>

那是css

 <style>
     .postion{
    position:relative;
    margin-left:-50%;
}
    </style>

Jquery代码将是这样的。

    <script type="text/javascript">
        $(document).ready(function () {

          jQuery('[data-toggle=offcanvas]').click(function () {

        // add this line to change the position of sidebar
        jQuery('.row-offcanvas').hasClass( "active" ) ? jQuery('.sidebar-offcanvas').css("position","absolute") :        jQuery('.sidebar-offcanvas').css("position","relative");  
        // end modif      

        $(".content-div").toggleClass("postion");


        jQuery('.row-offcanvas').toggleClass('active')
        });


        });
    </script>

这就是我们必须使用的东西。现在我正在解释这个问题。当我们点击按钮时，offcanvas div将添加相对的css位置。而另一个内容div将切换一个css将成为位置的类：relative;保证金左：-50％;

我从左到右，从右到左制作了两种类型的offcan。如果您愿意，可以从我的保管箱下载这两个代码。谢谢。
