2. Progress进度条例子
2.1. 使用脚手架新建一个名为element-ui-progress的前端项目, 同时安装Element插件。
2.2. 编写index.js
import Vue from 'vue'
import VueRouter from 'vue-router'
import Progress from '../components/Progress.vue'
import ColorProgress from '../components/ColorProgress.vue'
import DashboardProgress from '../components/DashboardProgress.vue'
Vue.use(VueRouter)
const routes = [
{ path: '/', redirect: '/Progress' },
{ path: '/Progress', component: Progress },
{ path: '/ColorProgress', component: ColorProgress },
{ path: '/DashboardProgress', component: DashboardProgress }
]
const router = new VueRouter({
routes
})
export default router
2.3. 在components在新建Progress.vue
<template>
<div>
<h1>线形进度条</h1>
<h4>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。</h4>
<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>
<h1>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</h1>
<h4>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。</h4>
<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>
<h1>环形进度条</h1>
<h4>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。</h4>
<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>
</div>
</template>
<script>
export default {
methods: {
format (percentage) {
return percentage === 100 ? '满' : `${percentage}%`
}
}
}
</script>
<style scoped>
.el-progress + .el-progress {
margin-top: 20px;
}
.el-progress--circle + .el-progress--circle {
margin-left: 20px;
}
</style>
2.4. 在components在新建ColorProgress.vue
<template>
<div>
<h1>自定义颜色</h1>
<h4>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。</h4>
<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>
</div>
</template>
<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>
<style scoped>
.el-progress + .el-progress {
margin-top: 20px;
}
</style>
2.5. 在components在新建DashboardProgress.vue
<template>
<div>
<h1>仪表盘形进度条</h1>
<h4>通过type属性来指定使用仪表盘形进度条。</h4>
<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>
</div>
</template>
<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>
