css - Bootstrap offcanvas 两侧(左侧和右侧)示例

Question

我正在尝试制作bootstrap offcanvas example为双方工作。到目前为止，我设法让它在两侧滑动，但由于我不太擅长使用 css，由于某种原因，菜单没有位于应有的位置。 bootply 中有非常相似的模板，所以这里有一个非常相似的例子，我在 here

$(document).ready(function() {
  $('[data-toggle="offcanvas"]').click(function () {
            $('.row-offcanvas-both').toggleClass('leftActive');
  });
  $('[data-toggle="offcanvas-right"]').click(function () {
    $('.row-offcanvas-both').toggleClass('rightActive');
  });
});

body {
  padding-top: 51px;  
}
.text-center {
  padding-top: 20px;
}
.col-xs-12 {
  background-color: #fff;
}
#sidebar {
  height: 100%;
  padding-right: 0;
  padding-top: 20px;
}
#sidebar .nav {
  width: 95%;
}
#sidebar li {
  border:0 #f2f2f2 solid;
  border-bottom-width:1px;
}

/* collapsed sidebar styles */
@media screen and (max-width: 767px) {
  .row-offcanvas {
    position: relative;
    -webkit-transition: all 0.25s ease-out;
    -moz-transition: all 0.25s ease-out;
    transition: all 0.25s ease-out;
  }
  .row-offcanvas-right
  .sidebar-offcanvas {
    right: -41.6%;
  }

  .row-offcanvas-left
  .sidebar-offcanvas {
    left: -41.6%;
  }
  .row-offcanvas-right.active {
    right: 41.6%;
  }
  .row-offcanvas-left.active {
    left: 41.6%;
  }
  .sidebar-offcanvas {
    position: absolute;
    top: 0;
    width: 41.6%;
  }
  #sidebar {
    padding-top:0;
  }


  /* something that I tried to make both sides work */
      .row-offcanvas-both
    .sidebar-offcanvas-rigth {
        right: -75%; /* 9 columns */
    }

    .row-offcanvas-both
    .sidebar-offcanvas-left {
        left: -75%; /* 9 columns */
    }
	
  	.row-offcanvas-both.rightActive {
        right: 75%; /* 9 columns */
    }

    .row-offcanvas-both.leftActive {
        left: 75%; /* 9 columns */
    }

  #sidebar-right {
    height: 100%;
    padding-right: 0;
    padding-top: 20px;
  }
  #sidebar-right .nav {
    width: 95%;
  }
  #sidebar-right li {
    border:0 #f2f2f2 solid;
    border-bottom-width:1px;
  }

#sidebar-right {
    padding-top:0;
  }
}

Answer 1

您的代码中存在一些严重错误和不需要的 CSS。

首先，您通过以下方式调用类 leftActive 和 rightActive:

$('[data-toggle="offcanvas"]').click(function () {
    $('.row-offcanvas-both').toggleClass('leftActive');
});

$('[data-toggle="offcanvas-right"]').click(function () {
    $('.row-offcanvas-both').toggleClass('rightActive');
});

但是在您的HTML中，类名对于左侧和右侧菜单都是active；

<ul class="nav">
     <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>

我纠正了在您的代码中发现的所有错误，并为您制作了一个工作示例，您可以在 this Bootply 中看到它.
