如何在iOS中调用按钮点击webview的快速函数？

import UIKit
import WebKit

class ViewController: UIViewController, WKNavigationDelegate {
    var webView: WKWebView!
    var button: UIButton!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建webview
        webView = WKWebView(frame: view.bounds)
        webView.navigationDelegate = self
        view.addSubview(webView)
        
        // 创建按钮
        button = UIButton(type: .system)
        button.frame = CGRect(x: 100, y: 100, width: 200, height: 50)
        button.setTitle("点击按钮", for: .normal)
        button.addTarget(self, action: #selector(buttonClicked), for: .touchUpInside)
        view.addSubview(button)
    }
    
    @objc func buttonClicked() {
        // 在按钮点击事件中调用webview的evaluateJavaScript方法执行JavaScript代码
        let javascript = "document.getElementById('buttonId').click();"
        webView.evaluateJavaScript(javascript, completionHandler: nil)
    }
}
