    <lay-step :active="active" current-status="primary">
        <lay-step-item title="First" content="First step"></lay-step-item>
        <lay-step-item title="Second" content="Second step"></lay-step-item>

::: title 设置第几步状态
:::

这里设置`status` 会覆盖掉`current-status`

::: demo

<template>
<div>
    <lay-step :active="active" current-status="warning">
        <lay-step-item title="First" content="First step"></lay-step-item>
        <lay-step-item status="fail" title="Second" content="Second step"></lay-step-item>
        <lay-step-item title="Third" content="Third step"></lay-step-item>
        <lay-step-item title="Fourth" content="Fourth step"></lay-step-item>
    </lay-step>
<lay-button size="xs" @click="nexts">下一步</lay-button>
<lay-button size="xs" @click="previous">上一步</lay-button>
</div>
</template>

<script>
import { ref } from 'vue';

export default {
  setup() {
    const loading = ref(true);
    const active = ref(-1);
    const nexts = () => {
      if (active.value++ >=3) active.value = 0
    };
    const previous = () => {
      if (active.value-- ===0) active.value = 0
    };
    return {
        loading,
        active
    }
  }
}
</script>
