1、跳转外部链接并覆盖当前页

<el-button type="primary" @click="jump">跳转</el-button>
    jump () {
      window.location.href = 'https:\\www.baidu.com'
    }

2、跳转不覆盖当前页面，在新窗口打开

<el-button type="primary" @click="jump">跳转</el-button>
    jump () {
      window.open = ('https:\\www.baidu.com','_blank')
    }

3、页面中内部跳转

用this.$router.push()实现
