JxBrowser

This dialog has First Name, Last Name, Phone, Email text fields, and New Account button. In Java application we need to display a dialog with this HTML content, let the user to fill all text fields and click New Account button. In Java code we need to be notified when user clicks the button, read text fields values to create a new account in our application. The following Java example demonstrates how we can do it with JxBrowser: (此对话框具有“名字”，“姓氏”，“电话”，“电子邮件”文本字段和“新帐户”按钮。在Java应用程序中，我们需要显示一个包含此HTML内容的对话框，让用户填写所有文本字段，然后单击“新帐户”按钮。在Java代码中，当用户单击按钮，读取文本字段值以在我们的应用程序中创建新帐户时，我们需要得到通知。以下Java示例演示了如何使用JxBrowser做到这一点：)
