Miscellaneous Notes (2)

Hide the scroll bar and keep the scroll effect


.outer-container {
    overflow: hidden;        // 隐藏滚动条
    width: 240px;          // 内容宽度，同时配合子元素
    height: 100%;
  }
  .inner-container {
    overflow-x: hidden; // 隐藏水平滚动条
    overflow-y: scroll;    // 产生垂直滚动
    width: 257px;       // 比父元素宽出滚动条的宽度 17px
    height: 100%;          // 设置产生滚动条
  }
  .inner-container::-webkit-scrollbar {
    display: none;            //  webkit 内核的浏览器仅需设置此属性
  }

// 另一种方法,在滚动的容器设置
.inner-container {
    margin-right: -17px;
}

错误:pathspec的字段与git已知的任何文件不匹配。

// 需要在提交时将描述信息放在两重引号中，原因疑是 git 无法识别 文件名或路径
git add .
git commit -m "'your message'"
git pull origin master
git push origin master

Check whether to jump after logging in to prevent an endless loop


router.beforeEach((to, from, next) => {
    out //判断登录状态简单实例
    var userInfo = window.localStorage.getItem('token');
    if (userInfo) {
        next();
    } else {
        next('/login');
    }
})

// 以上会发现出现如下错误：出现 dead loop错误,解决方法如下所示
// 解决思路：排除此时地址 = 转向的地址 的情况，避免dead loop
router.beforeEach((to, from, next) => {
    var userInfo = window.localStorage.getItem('token');//获取浏览器缓存的用户信息
    if(userInfo){ //如果有就直接到首页咯
        next();
    } else {
        if(to.path=='/login'){ //如果是登录页面路径，就直接next()
            next();
        } else { //不然就跳转到登录；
            next('/login');
        }

    }
})

Solutions:

// Edit node_modules\bootstrap\package.json: Remove these lines:

"last 1 major version",
">= 1%",

Use the font – awesome webpack – vue
NPM installs font-awesome and any dependencies it requires


npm install less less-loader css-loader style-loader file-loader font-awesome --save

Globally register font-awesome in the entry file


import 'font-awesome/css/font-awesome.min.css';

Configure the parsing


{
    test: /\.(gif|jpg|jpeg|png|woff|svg|eot|ttf)\??.*$/,
    loader: 'url-loader?limit=1024'
},
