C# Code
namespace SharpBrowser
{
public partial class WebViewTest : Form
{
public ChromiumWebBrowser chromeBrowser;
public WebViewTest()
{
InitializeComponent();
InitializeChromium();
}
//初始化浏览器并启动
public void InitializeChromium()
{
CefSettings settings = new CefSettings();
CefSharpSettings.LegacyJavascriptBindingEnabled = true;
// Initialize cef with the provided settings
Cef.Initialize(settings);
// Create a browser component
chromeBrowser = new ChromiumWebBrowser("http://172.16.0.66/C/");
CefSharpSettings.LegacyJavascriptBindingEnabled = true;
CefSharpSettings.WcfEnabled = true;
chromeBrowser.JavascriptObjectRepository.Register("jsObj", new SendCarBillPrint(), isAsync: false, options: BindingOptions.DefaultBinder);
// 将浏览器控件添加到当前Form窗体中
this.Controls.Add(chromeBrowser);
chromeBrowser.Dock = DockStyle.Fill; //充满显示
}
//窗体关闭时，记得停止浏览器
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
Cef.Shutdown(); //重要
}
}
class SendCarBillPrint
{
public string sendCode { set; get; }
public void invoke()
{
MessageBox.Show("JS 调用=>" + sendCode);
}
}
}
