Rate

Used for rating

Basic usage

:::demo Rate divides rating scores into several levels and these levels can be distinguished by using different background colors. By default background colors are the same, but you can assign them an array with three element to reflect three levels using the colors attribute, and their two thresholds can be defined by low-threshold and high-threshold, or you can assign them with a object which key is the threshold between two levels and value is the corresponding color.

<div class="block">
  <span class="demonstration">Default</span>
  <el-rate v-model="value1"></el-rate>
</div>
<div class="block">
  <span class="demonstration">Color for different levels</span>
  <el-rate
    v-model="value2"
    :colors="colors">
  </el-rate>
</div>

<script>
  export default {
    data() {
      return {
        value1: null,
        value2: null,
        colors: ['#99A9BF', '#F7BA2A', '#FF9900'] // same as { 2: '#99A9BF', 4: { value: '#F7BA2A', excluded: true }, 5: '#FF9900' }
      }
    }
  }
</script>

With text

Using text to indicate rating score

:::demo Add attribute show-text to display text at the right of Rate. You can assign texts for different scores using texts. texts is an array whose length should be equal to the max score max.

<el-rate
  v-model="value"
  :texts="['oops', 'disappointed', 'normal', 'good', 'great']"
  show-text>
</el-rate>

<script>
  export default {
    data() {
      return {
        value: null
      }
    }
  }
</script>

:::

More icons

You can use different icons to distinguish different rate components.

:::demo You can customize icons by passing icon-classes an array with three elements or a object which key is the threshold between two levels and value is the corresponding icon class. In this example, we also use void-icon-class to set the icon if it is unselected.

<el-rate
  v-model="value"
  :icon-classes="iconClasses"
  void-icon-class="icon-rate-face-off"
  :colors="['#99A9BF', '#F7BA2A', '#FF9900']">
</el-rate>

<script>
  export default {
    data() {
      return {
        value: null,
        iconClasses: ['icon-rate-face-1', 'icon-rate-face-2', 'icon-rate-face-3'] // same as { 2: 'icon-rate-face-1', 4: { value: 'icon-rate-face-2', excluded: true }, 5: 'icon-rate-face-3' }
      }
    }
  }
</script>

:::

Read-only

Read-only Rate is for displaying rating score. Half star is supported.

:::demo Use attribute disabled to make the component read-only. Add show-score to display the rating score at the right side. Additionally, you can use attribute score-template to provide a score template. It must contain {value}, and {value} will be replaced with the rating score.

<el-rate
  v-model="value"
  disabled
  show-score
  text-color="#ff9900"
  score-template="{value} points">
</el-rate>

<script>
  export default {
    data() {
      return {
        value: 3.7
      }
    }
  }
</script>
