使用Swift将具有JS文件的WKWebview中的按钮上的using捕获到iOS应用程序中

let webViewConfiguration = WKWebViewConfiguration()
webViewConfiguration.userContentController = WKUserContentController()

class MessageHandler: NSObject, WKScriptMessageHandler {
    func userContentController(_ userContentController: WKUserContentController, didReceive message: WKScriptMessage) {
        if let buttonId = message.body as? String {
            // 在这里处理从JavaScript传递过来的按钮ID
            print("Button ID: \(buttonId)")
        }
    }
}

let messageHandler = MessageHandler()
webViewConfiguration.userContentController.add(messageHandler, name: "buttonHandler")

document.getElementById("buttonId").addEventListener("click", function() {
    window.webkit.messageHandlers.buttonHandler.postMessage(this.id);
});

let webView = WKWebView(frame: view.bounds, configuration: webViewConfiguration)
view.addSubview(webView)
