UNIAPP全局方法封装全攻略

UNIAPP 自定义全局方法的方法

在 UNIAPP 开发中，自定义全局方法可以提升代码复用性和开发效率。以下是几种实现方式：

使用 Vue.prototype 挂载全局方法

在 main.js 中通过 Vue.prototype 挂载方法，所有页面和组件均可调用：

// main.js
import Vue from 'vue'
Vue.prototype.$utils = {
  showToast(msg) {
    uni.showToast({
      title: msg,
      icon: 'none'
    })
  }
}

调用方式：

this.$utils.showToast('操作成功')

通过模块化封装全局方法

创建独立工具模块并全局引入：

// utils/common.js
export default {
  formatDate(timestamp) {
    return new Date(timestamp).toLocaleString()
  }
}

// main.js
import common from './utils/common'
Vue.prototype.$common = common

使用 Mixin 实现方法共享

定义全局 mixin：

// mixins/global.js
export default {
  methods: {
    navigateTo(url) {
      uni.navigateTo({ url })
    }
  }
}

// main.js
import globalMixin from './mixins/global'
Vue.mixin(globalMixin)

挂载到 uni 对象上

通过修改 uni 对象扩展方法：

// main.js
uni.$http = function(options) {
  return uni.request(options)
}

注意事项

方法命名建议添加特定前缀（如 $）避免冲突
全局方法应保持功能单一性
对于复杂逻辑建议使用模块化方案
TypeScript 项目需扩展类型声明

// types/uni-app.d.ts
declare module 'vue/types/vue' {
  interface Vue {
    $utils: {
      showToast: (msg: string) => void
    }
  }
}

通过以上方式可实现高效、可维护的全局方法管理，根据项目复杂度选择合适方案。
