## Progress
|
|
|
|
Progress is used to show the progress of current operation, and inform the user the current status.
|
|
|
|
### Linear progress bar
|
|
|
|
:::demo Use `percentage` attribute to set the percentage. It's **required** and must be between `0-100`. You can custom text format by setting `format`.
|
|
```html
|
|
<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 ? 'Full' : `${percentage}%`;
|
|
}
|
|
}
|
|
};
|
|
</script>
|
|
<!--
|
|
<setup>
|
|
|
|
import { defineComponent } from 'vue';
|
|
|
|
export default defineComponent({
|
|
setup() {
|
|
const format = (percentage) => (percentage === 100 ? 'Full' : `${percentage}%`);
|
|
return {
|
|
format,
|
|
};
|
|
},
|
|
});
|
|
|
|
</setup>
|
|
-->
|
|
```
|
|

|
|
|
|
### Internal percentage
|
|
|
|
In this case the percentage takes no additional space.
|
|
|
|
:::demo `stroke-width` attribute decides the `width` of progress bar, and use `text-inside` attribute to put description inside the progress bar.
|
|
```html
|
|
<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>
|
|
```
|
|
:::
|
|
|
|
### Custom color
|
|
|
|
You can use `color` attr to set the progress bar color. it accepts color string, function, or array.
|
|
|
|
:::demo
|
|
|
|
```html
|
|
<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>
|
