Tabs

根据浏览记录自动记录历史 tab

使用

基础用法

将自动记录路由变化

<template>
  <pro-tabs />
</template>

风格类型 

<template>
  <pro-radio-button
    v-model="type"
    :data="data"
    style="margin-bottom: 16px"
  />
  <pro-tabs
    ref="childTabs"
    :type="type"
  />
</template>

<script>
import { defineComponent, inject, onMounted, ref, shallowRef } from 'vue'

export default defineComponent({
  setup() {
    const tabs = inject('tabs', undefined) // Get top-level `Tabs` inject
    const childTabs = shallowRef({})
    const type = ref('')
    const data = [
      { value: '', label: 'Default' },
      { value: 'card', label: 'Card' },
      { value: 'border-card', label: 'BorderCard' },
    ]

    onMounted(() => {
      asyncList()
    })

    function asyncList() {
      if (tabs) {
        childTabs.value.list = tabs.value.list
      }
    }

    return {
      childTabs,
      type,
      data,
    }
  },
})
</script>

保持隐藏路由

默认自动关闭具有 hidden 标识的路由，可以通过 keep-hidden-route 阻止这种行为

<template>
  <pro-tabs keep-hidden-route />
</template>

外部调用关闭

通过 ref 绑定 Tabs 进而通过外部调用关闭 tab 页

const tabs = inject('tabs') 由顶层 Layout 注入 参考

<template>
  <pro-tabs
    ref="childTabs"
    style="margin-bottom: 15px"
  />
  <el-button @click="childTabs.close('/en-US/guide/')">
    Close homepage
  </el-button>
  <el-button @click="childTabs.closeOther">
    Close otherpage
  </el-button>
  <el-button @click="asyncList">
    async
  </el-button>
</template>

<script>
import { defineComponent, inject, onMounted, shallowRef } from 'vue'

export default defineComponent({
  setup() {
    const tabs = inject('tabs', undefined) // Get top-level `Tabs` inject
    const childTabs = shallowRef({})

    onMounted(() => {
      asyncList()
    })

    function asyncList() {
      if (tabs) {
        childTabs.value.list = tabs.value.list
      }
    }

    return {
      childTabs,
      asyncList,
    }
  },
})
</script>

增加标签之前

通过 before-add 钩子在标签增加前执行一些操作，若返回 false 或者返回 Promise 且被 reject，则阻止增加标签

<template>
  <pro-tabs :before-add="beforeAdd" />
</template>

<script>
import { defineComponent, nextTick } from 'vue'
import { ElNotification } from 'element-plus'

export default defineComponent({
  setup() {
    function beforeAdd(e) {
      console.log('Tabs-before-add', e)
      nextTick(() => {
        ElNotification({
          type: 'success',
          title: 'Success',
          message: 'Come from before-add',
        })
      })
    }

    return {
      beforeAdd,
    }
  },
})
</script>

切换标签之前

通过 before-leave 钩子在标签切换前执行一些操作，若返回 false 或者返回 Promise 且被 reject，则阻止切换标签

<template>
  <pro-tabs
    ref="childTabs"
    :before-leave="beforeLeave"
  />
</template>

<script>
import { defineComponent, inject, onMounted, shallowRef } from 'vue'
import { ElNotification } from 'element-plus'

export default defineComponent({
  setup() {
    const tabs = inject('tabs', undefined) // Get top-level `Tabs` inject
    const childTabs = shallowRef({})

    onMounted(() => {
      asyncList()
    })

    function asyncList() {
      if (tabs) {
        childTabs.value.list = tabs.value.list
      }
    }

    function beforeLeave(activeName, oldActiveName) {
      console.log({ activeName, oldActiveName })
      ElNotification({
        type: 'success',
        title: 'Success',
        message: 'Come from before-leave',
      })
      return false
    }

    return {
      childTabs,
      beforeLeave,
    }
  },
})
</script>
