• vue中保存和获取cookie,读写cookie以及设置有效时间等,使用js-cookie


    1. NPM 安装
    npm install js-cookie --save
    复制代码
    1. 引入
    import Cookies from 'js-cookie'
    复制代码
    1. 设置cookie,创建一个cookie,在整个站点有效:
    cookies.set('name','value')
    复制代码

    或 创建一个过期的cookie,该cookie对当前页的路径有效:

    cookies.set('name','value',{expires:7,path:'})
    复制代码
    1. 获取cookie:
    cookies.get('name');//=>'值'
    复制代码
    1. 读取所有可见的Cookie:
    cookies.get();//=>{name:'value'}
    复制代码
    1. 删除Cookie:
    cookies.remove('name');
    复制代码
    1. 删除对当前页路径有效的cookie:
    cookies.set('name','value',{path:'});
    
    cookies.remove('name');//失败!
    
    cookies.remove('name',{path:'});//remove!
    复制代码

    Forexample:

    <template>
        <div class="login-wrap">
            <div class="ms-login">
                <div class="ms-title">后台管理系统</div>
                <el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="0px" class="ms-content">
                    <el-form-item prop="username">
                        <el-input v-model="ruleForm.username" placeholder="请输入用户名">
                            <el-button slot="prepend" icon="el-icon-lx-people"></el-button>
                        </el-input>
                    </el-form-item>
                    <el-form-item prop="password">
                        <el-input type="password" placeholder="请输入密码" v-model="ruleForm.password"
                                  @keyup.enter.native="submitForm('ruleForm')">
                            <el-button slot="prepend" icon="el-icon-lx-lock"></el-button>
                        </el-input>
                    </el-form-item>
                    <div class="login-btn">
                        <el-button type="primary" @click="submitForm('ruleForm')">登录</el-button>
                    </div>
                   
                </el-form>
            </div>
        </div>
    </template>
