我使用htmlunit庫來報廢Yellowpages.com網站。我想輸入搜索詞並點擊查找按鈕。但之後，我得到2頁：http://www.yellowpages.com/ny/sport?g=NY&q=Sport和https://dealoftheday.yellowpages.com/join?ic=deal_pop-under_signup-v- 第一個是我想要的，第二個是彈出。 我有這樣的代碼：如何獲得正確的頁面？
public void getPage() throws FailingHttpStatusCodeException, MalformedURLException, IOException {
WebClient webClient = new WebClient();
page = webClient.getPage("http://www.yellowpages.com");
HtmlTextInput searchInput = (HtmlTextInput) page.getElementById("search-terms");
searchInput.setText("Law");
HtmlSubmitInput button = (HtmlSubmitInput) page.getElementById("search-submit");
page = button.click();
System.out.println(page.getTitleText());
}
此代碼打印：
Deal of the Day on YP.com - Join
但我想打印第一頁標題，那就是：
NY Sport | Sport in NY - YP.com
如何獲得第一頁？
編輯：添加行webClient.setPopupBlockerEnabled（true）後，我收到了很多警告，之後，我得到了異常。這裏是控制檯輸出的一部分：

我已經找到解決方案了，無論如何謝謝。你說得對，webClient.setThrowExceptionOnScriptError（false）是解決方案。 –
