Progress 进度条

用于展示操作进度,告知用户当前状态和预期。

线形进度条

:::demo Progress 组件设置percentage属性即可,表示进度条对应的百分比,必填,必须在 0-100。通过 format 属性来指定进度条文字内容。

<el-progress :percentage="50"></el-progress>
<el-progress :percentage="100" :format="format"></el-progress>
<el-progress :percentage="100" status="success"></el-progress>
<el-progress :percentage="100" status="warning"></el-progress>
<el-progress :percentage="50" status="exception"></el-progress>

<script>
  export default {
    methods: {
      format(percentage) {
        return percentage === 100 ? '满' : `${percentage}%`;
      }
    }
  };
</script>
<!--
<setup>

  import { defineComponent } from 'vue';

  export default defineComponent({
    setup() {
      const format = (percentage) => (percentage === 100 ? '满' : `${percentage}%`);
      return {
        format,
      };
    },
  });

</setup>
-->

:::

百分比内显

百分比不占用额外控件,适用于文件上传等场景。

:::demo Progress 组件可通过 stroke-width 属性更改进度条的高度,并可通过 text-inside 属性来将进度条描述置于进度条内部。

<el-progress :text-inside="true" :stroke-width="26" :percentage="70"></el-progress>
<el-progress :text-inside="true" :stroke-width="24" :percentage="100" status="success"></el-progress>
<el-progress :text-inside="true" :stroke-width="22" :percentage="80" status="warning"></el-progress>
<el-progress :text-inside="true" :stroke-width="20" :percentage="50" status="exception"></el-progress>

:::

自定义颜色

可以通过 color 设置进度条的颜色,color 可以接受颜色字符串,函数和数组。

:::demo

<el-progress :percentage="percentage" :color="customColor"></el-progress>

<el-progress :percentage="percentage" :color="customColorMethod"></el-progress>

<el-progress :percentage="percentage" :color="customColors"></el-progress>

<el-progress :percentage="percentage2" :color="customColors"></el-progress>
<div>
  <el-button-group>
    <el-button icon="el-icon-minus" @click="decrease"></el-button>
    <el-button icon="el-icon-plus" @click="increase"></el-button>
  </el-button-group>
</div>

<script>
  export default {
    data() {
      return {
        percentage: 20,
        percentage2: 0,
        customColor: '#409eff',
        customColors: [
          {color: '#f56c6c', percentage: 20},
          {color: '#e6a23c', percentage: 40},
          {color: '#5cb87a', percentage: 60},
          {color: '#1989fa', percentage: 80},
          {color: '#6f7ad3', percentage: 100}
        ]
      };
    },
    methods: {
      customColorMethod(percentage) {
        if (percentage < 30) {
          return '#909399';
        } else if (percentage < 70) {
          return '#e6a23c';
        } else {
          return '#67c23a';
        }
      },
      increase() {
        this.percentage += 10;
        if (this.percentage > 100) {
          this.percentage = 100;
        }
      },
      decrease() {
        this.percentage -= 10;
        if (this.percentage < 0) {
          this.percentage = 0;
        }
      }
    },
    mounted() {
      setInterval(() => {
        this.percentage2 = (this.percentage2 % 100) + 10
      }, 500)
    }
  }
</script>
<!--
<setup>

  import { defineComponent, reactive, toRefs } from 'vue';

  export default defineComponent({
    setup() {
      const state = reactive({
        percentage: 20,
        customColor: '#409eff',
        customColors: [
          { color: '#f56c6c', percentage: 20 },
          { color: '#e6a23c', percentage: 40 },

环形进度条

Progress 组件可通过 type 属性来指定使用环形进度条,在环形进度条中,还可以通过 width 属性来设置其大小。

:::demo

<el-progress type="circle" :percentage="0"></el-progress>
<el-progress type="circle" :percentage="25"></el-progress>
<el-progress type="circle" :percentage="100" status="success"></el-progress>

:::

自定义内容

:::demo 通过默认插槽添加自定义内容。

<el-progress :percentage="50">
  <el-button type="text">自定义内容</el-button>
</el-progress>
<el-progress :text-inside="true" :stroke-width="20" :percentage="50" status="exception">
  <span>自定义内容</span>
</el-progress>
<el-progress type="circle" :percentage="100" status="success">
  <el-button type="success" icon="el-icon-check" circle></el-button>
</el-progress>
<el-progress type="dashboard" :percentage="80">
  <template #default="{ percentage }">
    <span class="percentage-value">{{ percentage }}%</span>
    <span class="percentage-label">当前进度</span>
  </template>
</el-progress>

:::

动画进度条

:::demo Progress 组件设置 indeterminate 属性控制进度条运动。通过设置 duration 属性可以控制运动速度。

<el-progress :percentage="50" :indeterminate="true"></el-progress>
<el-progress :percentage="100" :format="format" :indeterminate="true"></el-progress>
<el-progress :percentage="100" status="success" :indeterminate="true" :duration="5"></el-progress>
<el-progress :percentage="100" status="warning" :indeterminate="true" :duration="1"></el-progress>
<el-progress :percentage="50" status="exception" :indeterminate="true"></el-progress>

<script>
  export default {
    methods: {
      format(percentage) {
        return percentage === 100 ? '满' : `${percentage}%`;
      }
    }
  };
</script>
<!--
<setup>

  import { defineComponent } from 'vue';

  export default defineComponent({
    setup() {
      const format = (percentage) => (percentage === 100 ? '满' : `${percentage}%`);
      return {
        format,
      };
    },
  });

</setup>
