Switch

Switch is used for switching between two opposing states.

Basic usage

:::demo Bind v-model to a Boolean typed variable. The active-color and inactive-color attribute decides the background color in two states.

<el-switch v-model="value1"> </el-switch>
<el-switch v-model="value2" active-color="#13ce66" inactive-color="#ff4949">
</el-switch>

<script>
  export default {
    data() {
      return {
        value1: true,
        value2: true,
      }
    },
  }
</script>

Text description

:::demo You can add active-text and inactive-text attribute to show texts.

<el-switch
  v-model="value1"
  active-text="Pay by month"
  inactive-text="Pay by year"
>
</el-switch>
<el-switch
  style="display: block"
  v-model="value2"
  active-color="#13ce66"
  inactive-color="#ff4949"
  active-text="Pay by month"
  inactive-text="Pay by year"
>
</el-switch>

<script>
  export default {
    data() {
      return {
        value1: true,
        value2: true,
      }
    },
  }
</script>

:::

Extended value types

:::demo You can set active-value and inactive-value attributes. They both receive a Boolean, String or Number typed value.

<el-tooltip :content="'Switch value: ' + value" placement="top">
  <el-switch
    v-model="value"
    active-color="#13ce66"
    inactive-color="#ff4949"
    active-value="100"
    inactive-value="0"
  >
  </el-switch>
</el-tooltip>

<script>
  export default {
    data() {
      return {
        value: '100',
      }
    },
  }
</script>

:::

Disabled

:::demo Adding the disabled attribute disables Switch.

<el-switch v-model="value1" disabled> </el-switch>
<el-switch v-model="value2" disabled> </el-switch>

<script>
  export default {
    data() {
      return {
        value1: true,
        value2: false,
      }
    },
  }
</script>

:::

Loading

:::demo Setting the loading attribute to true indicates a loading state on the Switch.

<el-switch v-model="value1" loading> </el-switch>
<el-switch v-model="value2" loading> </el-switch>
<script>
  export default {
    data() {
      return {
        value1: true,
        value2: false,
      }
    },
  }
</script>

:::

prevent switching

:::demo set the before-change property, If false is returned or a Promise is returned and then is rejected, will stop switching.

<el-switch v-model="value1" :loading="loading1" :before-change="beforeChange1">
</el-switch>
<el-switch v-model="value2" :loading="loading2" :before-change="beforeChange2">
</el-switch>
<script>
  import { reactive, toRefs } from 'vue'
  import { ElMessage } from 'element-plus'

  export default {
    setup() {
      const status1 = reactive({
        value1: false,
        loading1: false,
      })

      const beforeChange1 = () => {
        status1.loading1 = true
        return new Promise((resolve) => {
          setTimeout(() => {
            status1.loading1 = false
            ElMessage.success('switch success')
            return resolve(true)
          }, 1000)
        })
      }

      const status2 = reactive({
        value2: false,
        loading2: false,
      })

      const beforeChange2 = () => {
        status2.loading2 = true
        return new Promise((resolve, reject) => {
          setTimeout(() => {
            status2.loading2 = false
            ElMessage.error('switch failed')
            return reject(new Error('error'))
          }, 1000)
        })
      }

      return {
        ...toRefs(status1),
        ...toRefs(status2),
        beforeChange1,
        beforeChange2,
      }
    },
  }
</script>
