写在 JSbridge.js
let isAndroid = navigator.userAgent.indexOf('Android') > -1 || navigator.userAgent.indexOf('Adr') > -1;
let isiOS = !!navigator.userAgent.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/);
//这是必须要写的,用来创建一些设置
function setupWebViewJavascriptBridge(callback) {
//Android使用
if (isAndroid) {
if (window.WebViewJavascriptBridge) {
callback(WebViewJavascriptBridge)
} else {
document.addEventListener(
'WebViewJavascriptBridgeReady',
function () {
callback(WebViewJavascriptBridge)
},
false
);
}
console.log('tag', '安卓')
sessionStorage.phoneType = 'android'
}
//iOS使用
if (isiOS) {
if (window.WebViewJavascriptBridge) {
return callback(WebViewJavascriptBridge);
}
if (window.WVJBCallbacks) {
return window.WVJBCallbacks.push(callback);
}
window.WVJBCallbacks = [callback];
var WVJBIframe = document.createElement('iframe');
WVJBIframe.style.display = 'none';
WVJBIframe.src = 'wvjbscheme://__BRIDGE_LOADED__';
document.documentElement.appendChild(WVJBIframe);
setTimeout(function () {
document.documentElement.removeChild(WVJBIframe)
}, 0);
console.log('tag', 'ios');
sessionStorage.phoneType = 'ios'
}
}
//注册回调函数,第一次连接时调用 初始化函数(android需要初始化,ios不用)
setupWebViewJavascriptBridge(function (bridge) {
if (isAndroid) {
//初始化
bridge.init(function (message, responseCallback) {
var data = {
'Javascript Responds': 'Wee!'
};
responseCallback(data);
})
}
})
export default {
// js调APP方法 (参数分别为:app提供的方法名 传给app的数据 回调)
callHandler(name, data, callback) {
setupWebViewJavascriptBridge(function (bridge) {
bridge.callHandler(name, data, callback)
})
},
// APP调js方法 (参数分别为:js提供的方法名 回调)
registerHandler(name, callback) {
setupWebViewJavascriptBridge(function (bridge) {
bridge.registerHandler(name, function (data, responseCallback) {
callback(data, responseCallback)
})
})
}
}
main.js中引入:
import Bridge from './config/JSbridge.js'
Vue.prototype.$bridge = Bridge
组件中使用:
方法名和app开发人员沟通好,这里js调app,app提供的方法是dataToAndroid;app调js,js提供的方法是dataToJs
注册方法
mounted(){
this.getAPPDate()
},
js调app
sendMsg(){
let msg = this.msg
this.$bridge.callHandler('dataToAndroid',msg,(res)=>{
alert('获取app响应数据:'+res)
this.test = res
})
},
app调js
getAPPDate(){
this.$bridge.registerHandler('dataToJs', (data, responseCallback) => {
alert('app主动调用js方法,传入数据:'+ data)
responseCallback(data)
})
}
