为什么HtmlButton object.click()在HtmlUnit中不起作用？

Question

我从一个html+javascipt页面获得了htmlbutton，但是我的代码不能工作(Eclipse中的JUnit+HtmlUnit)，代码是：

final HtmlPage page = (HtmlPage)webClient.getPage(url);
final HtmlForm form = page.getFormByName("registrationForm");
final HtmlButton button=(HtmlButton)page.getElementById("submit1"); 

final HtmlTextInput phone = form.getInputByName("phoneno");

phone.setValueAttribute("1234567890");

// Now submit the form by clicking the button and get back the second page.

final HtmlPage page2 = button.click();  //this doesn't work
final String pageAsXml = page2.asText();
System.out.println(pageAsXml);

这行评论"this‘t work“有一些problem.there is no error，但它不工作。webclient构造函数有什么问题吗？我们需要指定浏览器版本作为参数吗？这能在eclipse中工作吗？

Answer 1

final HtmlPage page = (HtmlPage)webClient.getPage(url);
final HtmlForm form = page.getFormByName("registrationForm");
final HtmlButton button=(HtmlButton)form.getElementById("submit1"); 
//instead of page try using the form
final HtmlTextInput phone = form.getInputByName("phoneno");

phone.setValueAttribute("1234567890");

// Now submit the form by clicking the button and get back the second page.

final HtmlPage page2 = button.click();  //this doesn't work
final String pageAsXml = page2.asText();
System.out.println(pageAsXml);

//Let me know if it works.
