C# 严重错误：“；“浏览器尚未初始化”；何时执行；ExecuteScriptAsync“；或；EvaluateScript Async“；

我正在尝试使用CeSharp执行javascript。 最后我犯了一个错误： 浏览器尚未初始化。使用IsBrowserInitializedChanged事件并检查IsBrowserInitialized属性以确定浏览器何时已初始化

当我使用这样的：“ExecuteScriptAsync”方法时

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using CefSharp;
using CefSharp.WinForms;

namespace CefSharp
{

    public partial class Form1 : Form
    {
        public ChromiumWebBrowser chromeBrowser;


        public Form1()
        {
            InitializeComponent();
            // Start the browser after initialize global component
            InitializeChromium();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            chromeBrowser.ExecuteScriptAsync("alert('Adam')");
        }

        public void InitializeChromium()
        {
            CefSettings settings = new CefSettings
            {
                CachePath = "cache"
            };
            // Initialize cef with the provided settings
            Cef.Initialize(settings);
            // Create a browser component
            chromeBrowser = new ChromiumWebBrowser("http://localhost/Test/index.html");

            // Add it to the form and fill it to the form window.
            this.Controls.Add(chromeBrowser);
            chromeBrowser.Dock = DockStyle.Fill;
        }

        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            Cef.Shutdown();
        }
    }    
}

或者当我使用“EvaluateScript异步”

有人知道如何处理吗？

请参阅Hi@amaitland有没有办法获取文档（就像我们可以在默认的webbrowser控件上获取文档一样）？还可以检查浏览器的readyState=“completed”吗？您只能通过JavaScript访问DOM。你需要知道readystate的确切用途是什么？如果你在LoadingStateChanged中执行JavaScript，那么文档应该是readyHard，不足以继续。在执行

JavaScript

之前，需要确保浏览器已充分加载。请重新阅读我提供的链接，也许吧？
