Element Plus Steps 基础用法
基本步骤条实现
<template>
<el-steps :active="currentStep" align-center>
<el-step title="步骤一" description="创建项目" />
<el-step title="步骤二" description="部门初审" />
<el-step title="步骤三" description="财务复核" />
<el-step title="步骤四" description="完成" />
</el-steps>
</template>
<script setup lang="ts">
import { ref } from 'vue'
const currentStep = ref(0)
</script>
带详细信息的步骤条
<template>
<el-steps :active="2" class="w-[90%] m-auto">
<el-step title="创建项目">
<template #description>
<p>负责人：张三</p>
<p>2024-01-15 10:30:00</p>
</template>
</el-step>
<el-step title="部门初审">
<template #description>
<p class="flex items-center">
李四
<el-button type="text" size="small">催一下</el-button>
</p>
</template>
</el-step>
<el-step title="财务复核" />
<el-step title="完成" />
</el-steps>
</template>
步骤条状态管理
<script setup lang="ts">
import { ref } from 'vue'
const steps = ref([
{ title: '步骤一', status: 'wait' },
{ title: '步骤二', status: 'process' },
{ title: '步骤三', status: 'wait' },
{ title: '步骤四', status: 'wait' }
])
const currentStep = ref(1)
// 下一步
const nextStep = () => {
if (currentStep.value < steps.value.length - 1) {
steps.value[currentStep.value].status = 'finish'
currentStep.value++
steps.value[currentStep.value].status = 'process'
}
}
// 上一步
const prevStep = () => {
if (currentStep.value > 0) {
steps.value[currentStep.value].status = 'wait'
currentStep.value--
steps.value[currentStep.value].status = 'process'
}
}
</script>
PlusProComponents StepsForm 高级用法
多步骤表单集成
<script setup lang="ts">
import { ref } from 'vue'
import { PlusStepsForm } from 'plus-pro-components'
const stepForm = ref([
{
title: "基本信息",
form: {
labelPosition: "top",
style: { width: "400px", margin: "40px auto" },
modelValue: {},
columns: [
{
label: "项目名称",
prop: "name",
valueType: "input",
rules: [{ required: true, message: "请输入项目名称" }]
},
{
label: "项目状态",
prop: "status",
valueType: "select",
options: [
{ label: "未开始", value: "0" },
{ label: "进行中", value: "1" },
{ label: "已完成", value: "2" }
]
}
]
}
},
{
title: "详细配置",
form: {
modelValue: {},
columns: [
{
label: "开始时间",
prop: "startTime",
valueType: "date-picker"
},
{
label: "结束时间",
prop: "endTime",
valueType: "date-picker"
}
]
}
}
])
const activeStep = ref(0)
const handleNext = (step: number, values: any) => {
activeStep.value = step
console.log('当前步骤:', step, '表单值:', values)
}
</script>
<template>
<PlusStepsForm
v-model="activeStep"
:data="stepForm"
align-center
@next="handleNext"
/>
</template>
步骤表单验证流程
自定义步骤条组件
创建可复用Steps组件
<!-- src/components/ReSteps/index.vue -->
<template>
<div class="re-steps">
<el-steps
:active="active"
:align-center="alignCenter"
:simple="simple"
:class="customClass"
>
<el-step
v-for="(step, index) in steps"
:key="index"
:title="step.title"
:description="step.description"
:icon="step.icon"
:status="getStepStatus(index)"
/>
</el-steps>
<div v-if="showNavigation" class="step-navigation mt-4">
<el-button
v-if="active > 0"
@click="handlePrev"
:disabled="active === 0"
>
上一步
</el-button>
<el-button
v-if="active < steps.length - 1"
type="primary"
@click="handleNext"
>
下一步
</el-button>
<el-button
v-if="active === steps.length - 1"
type="success"
@click="handleComplete"
>
完成
</el-button>
</div>
</div>
</template>
<script setup lang="ts">
import { computed } from 'vue'
interface Step {
title: string
description?: string
icon?: string
}
interface Props {
steps: Step[]
active: number
alignCenter?: boolean
simple?: boolean
showNavigation?: boolean
customClass?: string
}
const props = withDefaults(defineProps<Props>(), {
alignCenter: true,
simple: false,
showNavigation: true,
customClass: ''
})
const emit = defineEmits(['update:active', 'next', 'prev', 'complete'])
const getStepStatus = (index: number) => {
if (index < props.active) return 'finish'
if (index === props.active) return 'process'
return 'wait'
}
const handleNext = () => {
if (props.active < props.steps.length - 1) {
const newActive = props.active + 1
emit('update:active', newActive)
emit('next', newActive)
}
}
const handlePrev = () => {
if (props.active > 0) {
const newActive = props.active - 1
emit('update:active', newActive)
emit('prev', newActive)
}
}
const handleComplete = () => {
emit('complete')
}
</script>
<style scoped>
.re-steps {
@apply w-full;
}
.step-navigation {
@apply flex justify-center gap-4;
}
</style>
使用自定义Steps组件
<template>
<ReSteps
:steps="steps"
:active="currentStep"
@next="handleStepNext"
@prev="handleStepPrev"
@complete="handleComplete"
/>
<div class="step-content mt-6">
<div v-if="currentStep === 0">
<h3>基本信息</h3>
<!-- 表单内容 -->
</div>
<div v-if="currentStep === 1">
<h3>详细配置</h3>
<!-- 表单内容 -->
</div>
<div v-if="currentStep === 2">
<h3>确认信息</h3>
<!-- 确认内容 -->
</div>
</div>
</template>
<script setup lang="ts">
import { ref } from 'vue'
import ReSteps from '@/components/ReSteps/index.vue'
const steps = ref([
{ title: '基本信息', description: '填写项目基础信息' },
{ title: '详细配置', description: '配置项目详细信息' },
{ title: '确认提交', description: '确认并提交项目' }
])
const currentStep = ref(0)
const handleStepNext = (step: number) => {
console.log('下一步:', step)
// 验证当前步骤数据
}
const handleStepPrev = (step: number) => {
console.log('上一步:', step)
}
const handleComplete = () => {
console.log('完成所有步骤')
// 提交所有数据
}
</script>
高级功能实现
动态步骤管理
<script setup lang="ts">
import { ref, computed } from 'vue'
interface StepConfig {
id: string
title: string
description?: string
required?: boolean
completed?: boolean
}
const steps = ref<StepConfig[]>([
{ id: 'base', title: '基本信息', required: true, completed: false },
{ id: 'config', title: '系统配置', required: true, completed: false },
{ id: 'advanced', title: '高级设置', required: false, completed: false },
{ id: 'review', title: '确认信息', required: true, completed: false }
])
const currentStepId = ref('base')
const currentStep = computed(() => {
return steps.value.findIndex(step => step.id === currentStepId.value)
})
const completedSteps = computed(() => {
return steps.value.filter(step => step.completed).length
})
const progress = computed(() => {
const requiredSteps = steps.value.filter(step => step.required)
const completedRequired = requiredSteps.filter(step => step.completed).length
return (completedRequired / requiredSteps.length) * 100
})
const canProceed = computed(() => {
const current = steps.value.find(step => step.id === currentStepId.value)
return current?.completed || !current?.required
})
const navigateToStep = (stepId: string) => {
const targetStep = steps.value.find(step => step.id === stepId)
if (targetStep && (targetStep.completed || !targetStep.required)) {
currentStepId.value = stepId
}
}
const markStepCompleted = (stepId: string, completed: boolean = true) => {
const step = steps.value.find(s => s.id === stepId)
if (step) {
step.completed = completed
}
}
</script>
步骤条与路由集成
// src/router/utils.ts
import { RouteRecordRaw } from 'vue-router'
export interface StepRoute {
path: string
name: string
title: string
order: number
required?: boolean
}
export const createStepRoutes = (steps: StepRoute[]): RouteRecordRaw[] => {
return steps.map(step => ({
path: step.path,
name: step.name,
component: () => import(`@/views/steps/${step.name}.vue`),
meta: {
step: step.order,
stepTitle: step.title,
required: step.required ?? true
}
}))
}
// 使用示例
export const projectSteps: StepRoute[] = [
{ path: 'base', name: 'ProjectBase', title: '基本信息', order: 1, required: true },
{ path: 'config', name: 'ProjectConfig', title: '配置设置', order: 2, required: true },
{ path: 'review', name: 'ProjectReview', title: '确认信息', order: 3, required: true }
]
最佳实践与性能优化
1. 步骤数据懒加载
<script setup lang="ts">
import { ref, shallowRef } from 'vue'
const steps = ref([
{ title: '步骤一', component: shallowRef(null) },
{ title: '步骤二', component: shallowRef(null) },
{ title: '步骤三', component: shallowRef(null) }
])
const currentStep = ref(0)
// 懒加载组件
const loadStepComponent = async (index: number) => {
if (!steps.value[index].component.value) {
const component = await import(`@/components/steps/Step${index + 1}.vue`)
steps.value[index].component.value = component.default
}
}
// 预加载下一步组件
const preloadNextStep = (currentIndex: number) => {
const nextIndex = currentIndex + 1
if (nextIndex < steps.value.length) {
loadStepComponent(nextIndex)
}
}
</script>
2. 步骤状态持久化
// src/utils/stepsPersist.ts
import { ref, watch } from 'vue'
import { useLocalStorage } from '@vueuse/core'
export const useStepsPersist = (key: string, initialSteps: any[]) => {
const persistedData = useLocalStorage(key, {
currentStep: 0,
stepsData: initialSteps.map(() => ({}))
})
const currentStep = ref(persistedData.value.currentStep)
const stepsData = ref(persistedData.value.stepsData)
watch([currentStep, stepsData], ([newStep, newData]) => {
persistedData.value = {
currentStep: newStep,
stepsData: newData
}
}, { deep: true })
const clearPersistedData = () => {
persistedData.value = {
currentStep: 0,
stepsData: initialSteps.map(() => ({}))
}
}
return {
currentStep,
stepsData,
clearPersistedData
}
}
常见问题解决方案
1. 步骤验证失败处理
<script setup lang="ts">
import { ref } from 'vue'
import { ElMessage } from 'element-plus'
const currentStep = ref(0)
const steps = ref([...])
const validateCurrentStep = async (): Promise<boolean> => {
try {
// 根据当前步骤进行验证
switch (currentStep.value) {
case 0:
return await validateStep1()
case 1:
return await validateStep2()
case 2:
return await validateStep3()
default:
return true
}
} catch (error) {
ElMessage.error('步骤验证失败')
return false
}
}
const handleNext = async () => {
const isValid = await validateCurrentStep()
if (isValid && currentStep.value < steps.value.length - 1) {
currentStep.value++
}
}
</script>
2. 步骤间数据传递
// src/composables/useStepsData.ts
import { ref, reactive } from 'vue'
export const useStepsData = () => {
const stepsData = reactive({
step1: {
name: '',
type: '',
description: ''
},
step2: {
config: {},
settings: {}
},
step3: {
reviewData: {},
confirmed: false
}
})
const updateStepData = (step: keyof typeof stepsData, data: any) => {
Object.assign(stepsData[step], data)
}
const getStepData = (step: keyof typeof stepsData) => {
return { ...stepsData[step] }
}
const resetAllData = () => {
Object.keys(stepsData).forEach(key => {
const stepKey = key as keyof typeof stepsData
if (Array.isArray(stepsData[stepKey])) {
stepsData[stepKey] = [] as any
} else {
stepsData[stepKey] = {} as any
}
})
}
return {
stepsData,
updateStepData,
getStepData,
resetAllData
}
}
