H5与原生IOS交互——WebViewJavascriptBridge
Web环境初始化
在入口文件index.html依次引入nativeMethods.js，jsMethods.js，bridge_regist.js
// JS调用native的方法: nativeMethods.js
var nativeMethodDefaultData = {
shareData: {
shareTitle: '',
shareDes: '',
shareImg: '',
shareUrl: '',
shareControl: '',
shareCopyTexts: '',
tdData: '',
isAuth: ''
},

shareId: '',
shareTo: '',
shareTitle: '',

shareImg: '',
shareUrl: '',
shareControl: '',
shareText: '',
shareImage: '',

// 原生调用js的方法：jsMethods.js
var jsMethodForNative = {

// console.log('native给的data', data)
//处理oc给的传参
var responseData = { 'result': 'handle success' }
//处理完，回调传值给oc
callback(responseData)
},
gotPhotos: function(data, callback) {
// window.photoData = data;
window.getPic(data);
//处理oc给的传参
var responseData = { 'result': 'handle success' }
//处理完，回调传值给oc
callback && callback(responseData)
}
}
// 函数注册：bridge_regist.js
var ClassmateNative = (function() {
var ua = window.navigator.userAgent.toLocaleLowerCase()
var isIos = /iphone|ipod|ipad/.test(ua)
// 注册方法， 参数是一个回调， WebViewJavascriptBridge会作为参数传入callback
var setupWebViewJavascriptBridge = function(callback) {
// console.log('注册用于交互注册的方法')

document.documentElement.appendChild(WVJBIframe)
setTimeout(function() {
document.documentElement.removeChild(WVJBIframe)
}, 0)
} else {

// 方法对象， 注册后的所有方法都放在这里

// 注册所有native提供给js调用的方法: callHandler
var registNativeMethodForJs = function(bridge) {

}
}
// 注册
setupWebViewJavascriptBridge(function(bridge) {
registNativeMethodForJs(bridge)
registJsMethodfornative(bridge)
})
return methodObj
})()
H5与原生交互——codova
在入口文件index.html中引入cordova.android.js ，然后和原生协同封装相同函数，进行调用。
// native.js
import { isInTxhApp, isAndroid, isJsbridge } from 'config'
const obj = {}
if (isJsbridge) {
obj.method = window.ClassmateNative
console.log('window.ClassmateNative.isJsbridge', window.ClassmateNative)
} else {
const ClassmateNative = {
/**
* 调用native方法
* @param interval 执行间隔时间
* @param callback 需要地的函数
* @param timeout 超时时间
*/
execNativeMethod: (interval, callback, timeout) => {
let timer = null
function intervalFun() {
timer = setTimeout(() => {
if (window.cordova.exec) {
callback()
clearTimeout(timer)
} else {
intervalFun(interval, callback)
}
}, interval)
}
intervalFun()
setTimeout(() => {
clearTimeout(timer)
}, timeout)
},
// 唤起native分享页面
callNativeShare: (data, success, error) => {
const options = {
shareId: '',
shareUrl: '',
tdData: '',
isAuth: ''
}
for (const d in data) {
options[d] = data[d]
}
const suc = success || null
const err = error || null
ClassmateNative.execNativeMethod(
20,
function() {
window.cordova.exec(suc, err, 'commTools', 'callNativeShare', [options])
},
5000
)
},
/**
* 获取设备ID
* 无参数
*/
getDeviceId: (data, success = null, error = null) => {
ClassmateNative.execNativeMethod(
20,
() => {
window.cordova.exec(success, error, 'commTools', 'getDeviceId', [data])
},
5000
)
},
/**
* 复制内容到剪贴板
*
*/
copyToClipboard: (options, success = null, error = null) => {
console.log('复制内容到剪贴板', options)
ClassmateNative.execNativeMethod(
20,
() => {
window.cordova.exec(success, error, 'commTools', 'copyToClipboard', [options])
},
2000
)
}
}
obj.method = ClassmateNative
console.log('cordova.ClassmateNative', ClassmateNative)
}
export default obj.method
