代码优化建议
- 使用 Vue 3 的响应式 API:Vue 3 中推荐使用
ref
或reactive
来创建响应式状态。6 - 简化模板中的条件渲染:避免在模板中使用多个
v-if
来渲染图片,可以使用计算属性来简化。4 - 优化事件监听:确保事件监听逻辑正确,并且使用 Vue 3 的
watch
函数来监听响应式数据的变化。210
优化后的代码示例
<template>
<div :class="['node', statusIcon]">
<img :src="image.logo" alt="logo" @click="setClick"/>
<span class="label">{{ label }}</span>
<img :src="image[statusIcon]" :alt="status">
</div>
</template>
<script setup>
import { ref, watch, inject } from 'vue'
import { ref as refImg } from '@/assets/img'
// 定义响应式状态
const status = ref('default')
const label = ref('')
// 注入依赖
const getNode = inject('getNode');
const data = getNode()?.getData() || {}
// 初始化响应式状态
watch(() => data, (newData) => {
label.value = newData.label
status.value = newData.status
})
// 图片资源
const image = {
logo: refImg('set.png'),
success: refImg('success.png'),
failed: refImg('failed.png'),
running: refImg('running.png')
}
// 根据状态返回对应的图片名称
const statusIcon = computed(() => status.value)
const setClick = () => {
// 点击事件处理逻辑
}
</script>
- 我使用了
ref
来创建响应式的状态变量status
和label
。 - 使用
watch
来监听data
对象的变化,并更新响应式状态。 - 通过计算属性
statusIcon
简化模板中的条件渲染,直接根据状态显示对应的图片。 - 假设
refImg
是一个辅助函数,用于引用图片资源,这里仅为示例,具体实现可能需要根据项目实际情况调整。6
