步骤总数和初始选择步骤 均可自定义设置，每个步骤title和description也均可自定义设置传入
效果图如下：
①创建步骤条组件Steps.vue：
<template>
<div class="m-steps-area">
<div class="m-steps">
<div
:class="['m-steps-item',
{ 'finished': current > n,
'process': current === n && n !== totalSteps,
'last-process': current === totalSteps && n === totalSteps,
'middle-wait': current < n && n !== totalSteps,
'last-wait': current < n && n === totalSteps,
}
]"
v-for="n in totalSteps"
:key="n"
@click="onChange(n)">
<div class="m-steps-icon">
<span class="u-icon" v-if="current<=n">{{ n }}</span>
<span class="u-icon" v-else>✓</span>
</div>
<div class="m-steps-content">
<div class="u-steps-title">{{ stepsLabel[n-1] || 'S ' + n }}</div>
<div class="u-steps-description">{{ stepsDesc[n-1] || 'Desc ' + n }}</div>
</div>
</div>
</div>
</div>
</template>
<script>

}
},

this.$emit('change', index)
}
}
}
}

</style>②在要使用的页面引入Steps组件，并传入相关初始数据：
<Steps :currentStep="1" :totalSteps="3" :stepsLabel="stepsLabel" :stepsDesc="stepsDesc" @change="onChange" />
import Steps from '@/components/Steps'
components: {
Steps
},
data () {
return {
stepsLabel: ['Step 1', 'Step 2', 'Step 3', 'Step 4', 'Step 5'],
stepsDesc: ['description 1', 'description 2', 'description 3', 'description 4', 'description 5']
}
}
methods: {
onChange (index) { // 父组件获取切换后的选中步骤
console.log('parentIndex:', index)
}
}
