@saryz/portal-bridge

用于iframe双向通信的封装

未来计划

返回promise以便可以在 async/await 时使用使代码逻辑更清晰

安装 install

npm i @saryz/portal-bridge -S

快速使用 Quick to use

监听 listen

import { PortalReceive } from "@saryz/portal-bridge"

// key 为子父约定 
PortalReceive.listen(key, ({ data }) => {
  // do something
})

触发 trigger

子->父 postToParent（子触发父方法）

import { PortalSend } from "@saryz/portal-bridge"

const params = { ... }
// key 为子父约定 
PortalSend.postToParent(key, params)

父->子 postToIframe（父触发子方法）

import { PortalSend } from "@saryz/portal-bridge"

const params = { ... }
// iframe:HTMLIFrameElement 
// const iframe = this.$refs.iframe // Vue
// const iframe = document.getElementById('iframe') // js
PortalSend.postToIframe(iframe, key, params)

回调 callback

获取父页面数据 Get the parent page data

/**** parent.js ****/
const key = 'getUserInfo'
const iframe = this.$refs.iframe
const params = { name: 'saryz', ... }
PortalReceive.listen(key, (data) => {
  console.log('Received data from iframe', data)
  PortalSend.postToIframe(iframe, key, params)
})

/**** child.js * example vue ****/
methods: {
  // get the parent page data 获取父页面数据
  getUserInfo()
  {
    const params = { msg: 'Please give me the user information' }
    const key = 'getUserInfo'
    PortalSend.postToParent(key, params, (data) => {
      console.log('parent page data', data)
      // do something
    })
  }
}

获取子页面数据 Get the child page data

/**** child.js ****/
const key = 'submit'
const params = { name: 'saryz', ... }
PortalReceive.listen(key, (data) => {
  console.log('father need me', data)
  // do something or What also not stem
  PortalSend.postToParent(key, params )
})

/**** father.js * example vue ****/
methods: {
  // get the parent page data 获取父页面数据
  submit()
  {
    const params = { msg: 'Mahler gobi submit!' }
    const key = 'submit'
    const iframe = this.$refs.iframe
    PortalSend.postToIframe(iframe, key, params, ({data}) => {
      console.log('child data', data) // { name: 'saryz', ... }
      // do something
    })
  }
}
