webapp js与安卓，ios怎么交互

/*这段代码是固定的，必须要放到js中*/function setupWebViewJavascriptBridge(callback) {

var u = navigator.userAgent;  var isiOS = !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/);  if (!isiOS) {      if (window.WebViewJavascriptBridge) {          callback(WebViewJavascriptBridge)      } else {          document.addEventListener(‘WebViewJavascriptBridgeReady‘, function (event) {              if(window.onWebViewJavascriptBridgeReady) window.onWebViewJavascriptBridgeReady(window.__bridge = WebViewJavascriptBridge);              callback(WebViewJavascriptBridge)          }, false)      }  } else {

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)  }

}

export default {

callhandler (name, data, callback) {    setupWebViewJavascriptBridge(function (bridge) {      bridge.callHandler(name, data, callback)    })  },

registerhandler (name, callback) {    setupWebViewJavascriptBridge(function (bridge) {      bridge.registerHandler(name, function (data, responseCallback) {        callback(data, responseCallback)      })    })  }}// 调用

this.$bridge.callhandler(‘shopCode‘,{‘test‘:‘test‘},(data) => { this.shopCode = data.shopCode;})
