必须这样写，如果用vue可以在app.vue里面写，先把WebViewJavascriptBridge弄到window下面 function setupWebViewJavascriptBridge(callback) { if ((window as any).WebViewJavascriptBridge) { return callback((window as any).WebViewJavascriptBridge); } if ((window as any).WVJBCallbacks) { return (window as any).WVJBCallbacks.push(callback); } (window as any).WVJBCallbacks = [callback]; var WVJBIframe = document.createElement('iframe'); WVJBIframe.style.display = 'none'; WVJBIframe.src = 'https://__bridge_loaded__'; document.documentElement.appendChild(WVJBIframe); setTimeout(function () { document.documentElement.removeChild(WVJBIframe) }, 0) } setupWebViewJavascriptBridge(function (bridge) { // window.JSBridge = bridge; }) 具体用的时候 js调用native（原生的，ios或者安卓端） (window as any).WebViewJavascriptBridge?.callHandler(native端的方法名, {参数}, (返回值) => {}) native调用js的 (window as any).WebViewJavascriptBridge?.registerHandler(native端的方法名, (返回值) => {})
