用于展示操作进度，告知用户当前状态和预期。

常见于操作流程进度或某项任务的状态。

1.如何使用？

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>

2.百分比内显

百分比不占用额外控件，适用于文件上传等场景。

/*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>

3.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。

<el-progress :percentage="percentage" :color="customColor"></el-progress><el-progress :percentage="percentage" :color="customColorMethod"></el-progress><el-progress :percentage="percentage" :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,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;}}}}
</script>

4.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。

<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>
<el-progress type="circle" :percentage="70" status="warning"></el-progress>
<el-progress type="circle" :percentage="50" status="exception"></el-progress>

 5.仪表盘形进度条

通过 type 属性来指定使用仪表盘形进度条。

<el-progress type="dashboard" :percentage="percentage" :color="colors"></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: 10,colors: [{color: '#f56c6c', percentage: 20},{color: '#e6a23c', percentage: 40},{color: '#5cb87a', percentage: 60},{color: '#1989fa', percentage: 80},{color: '#6f7ad3', percentage: 100}]};},methods: {increase() {this.percentage += 10;if (this.percentage > 100) {this.percentage = 100;}},decrease() {this.percentage -= 10;if (this.percentage < 0) {this.percentage = 0;}}}}
</script>
