如何在windows窗体中使用webview2获取单击的元素

private async void Form1_Load(object sender, EventArgs e)
{
    await webView21.EnsureCoreWebView2Async(null);
    webView21.CoreWebView2.DOMContentLoaded += CoreWebView2_DOMContentLoaded;
}

private void CoreWebView2_DOMContentLoaded(object sender, CoreWebView2DOMContentLoadedEventArgs e)
{
    webView21.CoreWebView2.ExecuteScriptAsync(@"
        document.addEventListener('click', function(e) {
            window.chrome.webview.postMessage(JSON.stringify({
                type: 'elementClick',
                target: e.target.outerHTML
            }));
        });
    ");
}

private void webView21_WebMessageReceived(object sender, CoreWebView2WebMessageReceivedEventArgs e)
{
    if (e.TryGetWebMessageAsString(out string message))
    {
        dynamic eventData = JObject.Parse(message);
        string eventType = eventData.type;

        if (eventType == "elementClick")
        {
            string targetElement = eventData.target;
            // 在这里处理单击元素的逻辑
        }
    }
}
