无法使用htmlunit点击谷歌地图页面上的链接

Question

目前，我正试图用htmlunit控制谷歌地图JP。 这是Google地图JP的a link。 在我的浏览器中，左侧有一个菜单（旧式视图），它在我点击县名后显示城市名称。我想通过使用htmlunit做同样的动作，但没有任何变化。 请给我一些想法并帮助我（使用servlet atm）。

package com.example.part1;

import java.io.IOException;
import javax.servlet.ServletException;

import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlPage;
import com.gargoylesoftware.htmlunit.html.HtmlAnchor;
import com.gargoylesoftware.htmlunit.NicelyResynchronizingAjaxController;


@WebServlet(“/test")

public class test extends HttpServlet {

private static final long serialVersionUID = 1L;



    public test() {

        super();

        // TODO Auto-generated constructor stub

    }


protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

// TODO Auto-generated method stub

java.util.logging.Logger.getLogger("com.gargoylesoftware").setLevel(java.util.logging.Level.OFF);

response.setContentType("text/html; charset=Windows-31J");
final WebClient webClient = new WebClient(BrowserVersion.CHROME, "198.23.143.27", 5555);
        webClient.getOptions().setThrowExceptionOnScriptError(false);
        webClient.getOptions().setThrowExceptionOnFailingStatusCode(false);
        webClient.getOptions().setJavaScriptEnabled(true);
        webClient.getOptions().setRedirectEnabled(true);
        webClient.getCookieManager().setCookiesEnabled(true);
        webClient.setAjaxController(new NicelyResynchronizingAjaxController());
        HtmlPage page1 = webClient.getPage("https://maps.google.co.jp/");        

        List<HtmlAnchor> links = (List<HtmlAnchor>) page1.getByXPath("//a[@href='javascript:void(0)']");


        //click 北海道
        links.get(12).click();

        webClient.waitForBackgroundJavaScript(10000);
        response.getWriter().write(page1.getWebResponse().getContentAsString());

}

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

// TODO Auto-generated method stub

}
}

这是a image file for explanation！

欢迎任何建议。 在此先感谢。

单击anchor时，将结果保存在HtmlPage中，如下所示：

page1  = links.get(12).click();

Edit.Added类点击按钮，还添加了点击
