## Progress

Progress est utilisé pour afficher la progression d'une opération et informer l'utilisateur de son status actuel.

### Barre de progression linéaire

:::demo Utilisez l'attribut `percentage` pour indiquer le pourcentage. Cet attribut est **requis** et doit être compris entre 0 et 100. Vous pouvez personnaliser le format du texte en définissant le `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>
```
:::

### Pourcentage interne

Dans ce cas le pourcentage ne prends pas de place en plus.

:::demo L'attribut `stroke-width` détermine le `width` de la barre de progression. Utilisez `text-inside` mettre la description à l'intérieur de la barre.
```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>
```

### Couleur personnalisée

Vous pouvez utiliser l'attribut `color` pour définir la couleur de la barre de progression. il accepte une couleur, une fonction ou un tableau.

:::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>
<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: '#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>
```
