Vue 实现 Steps 步骤条

使用 Element UI 的 Steps 组件

安装 Element UI 库：

npm install element-ui

在 Vue 文件中引入 Steps 组件：

<template>
  <div>
    <el-steps :active="active" finish-status="success">
      <el-step title="步骤 1"></el-step>
      <el-step title="步骤 2"></el-step>
      <el-step title="步骤 3"></el-step>
    </el-steps>
    <el-button @click="next">下一步</el-button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      active: 0
    }
  },
  methods: {
    next() {
      if (this.active++ > 2) this.active = 0
    }
  }
}
</script>

使用 Ant Design Vue 的 Steps 组件

安装 Ant Design Vue 库：

npm install ant-design-vue

在 Vue 文件中引入 Steps 组件：

<template>
  <div>
    <a-steps :current="current">
      <a-step title="步骤 1" />
      <a-step title="步骤 2" />
      <a-step title="步骤 3" />
    </a-steps>
    <a-button type="primary" @click="next">下一步</a-button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      current: 0
    }
  },
  methods: {
    next() {
      if (this.current++ > 2) this.current = 0
    }
  }
}
</script>

自定义 Steps 组件

创建一个自定义 Steps 组件：

<template>
  <div class="steps">
    <div
      v-for="(step, index) in steps"
      :key="index"
      class="step"
      :class="{ active: currentStep === index, completed: currentStep > index }"
    >
      <div class="step-circle">{{ index + 1 }}</div>
      <div class="step-title">{{ step.title }}</div>
    </div>
  </div>
</template>

<script>
export default {
  props: {
    steps: {
      type: Array,
      required: true
    },
    currentStep: {
      type: Number,
      default: 0
    }
  }
}
</script>

<style>
.steps {
  display: flex;
  justify-content: space-between;
  margin-bottom: 20px;
}
.step {
  flex: 1;
  text-align: center;
  position: relative;
}
.step-circle {
  width: 30px;
  height: 30px;
  border-radius: 50%;
  background: #ccc;
  color: white;
  display: flex;
  align-items: center;
  justify-content: center;
  margin: 0 auto 10px;
}
.step.active .step-circle {
  background: #409eff;
}
.step.completed .step-circle {
  background: #67c23a;
}
.step-title {
  color: #999;
}
.step.active .step-title {
  color: #409eff;
}
.step.completed .step-title {
  color: #67c23a;
}
</style>

在父组件中使用自定义 Steps 组件：

<template>
  <div>
    <custom-steps :steps="steps" :current-step="currentStep" />
    <button @click="nextStep">下一步</button>
  </div>
</template>

<script>
import CustomSteps from './CustomSteps.vue'

export default {
  components: {
    CustomSteps
  },
  data() {
    return {
      steps: [
        { title: '第一步' },
        { title: '第二步' },
        { title: '第三步' }
      ],
      currentStep: 0
    }
  },
  methods: {
    nextStep() {
      if (this.currentStep < this.steps.length - 1) {
        this.currentStep++
      }
    }
  }
}
</script>
