HtmlUnit 点击 Href “图片”

Question

任何想法如何用HtmlUnit点击这个“图像”？

<a href="play.php?choose=2">
<div id="champbox" style="background-image: url(http:xxx.jpg);float:right;"></div></a>

尝试使用 HtmlAnchor 和 Xpath 来单击它，但出现如下错误：

java.lang.NullPointerException

或

com.gargoylesoftware.htmlunit.ElementNotFoundException: elementName=[a] attributeName=[href] attributeValue=[play.php?choose=2]

我的代码：

        //Webclient Options
        final WebClient webClient = new WebClient(BrowserVersion.FIREFOX_45);
        webClient.getOptions().setRedirectEnabled(true);
        webClient.getOptions().setThrowExceptionOnScriptError(false);
        webClient.getOptions().setCssEnabled(false);
        webClient.getOptions().setUseInsecureSSL(true);
        webClient.getOptions().setThrowExceptionOnFailingStatusCode(false);
        webClient.getCookieManager().setCookiesEnabled(false);
        webClient.getOptions().setJavaScriptEnabled(true);


java.util.logging.Logger.getLogger("com.gargoylesoftware").setLevel(Level.OFF);
    System.setProperty("org.apache.commons.logging.Log", "org.apache.commons.logging.impl.NoOpLog");


    // Cut out the Login (better Overview)

    HtmlAnchor anchor = page2.getAnchorByHref("play.php");
    HtmlPage page3 = anchor.click();
    System.out.println(page3.getTitleText());
    System.out.println(page3.getUrl());

    //To-Do: Click left or right Picture

    /*
    HtmlAnchor a1 = page3.getAnchorByHref("play.php?choose=2");
    System.out.println(a1.asXml());
    HtmlAnchor a2 = page3.getFirstByXPath("//a[@href='play.php?choose=2']");
    System.out.println(a2.asXml());

    a1.click();
    a2.click();
    */
    /*
    ScriptResult result = page3.executeJavaScript("vapi-client.js:41");
    result.getJavaScriptResult();
    System.out.println("result: "+ result);
    */

Answer 1

不确定您是否在谈论此问题，但如果您想更改光标以向某人显示您可以单击图像：

.champbox {
  cursor:pointer;
}

Answer 2

您的案例适用于最新版本/快照。

<a href="play.php?choose=2">
  <div id="champbox" style="background-image: url(http:xxx.jpg);float:right;"></div>
</a>

try (WebClient webClient = new WebClient()) {
    HtmlPage page = webClient.getPage("http://localhost:8080");
    HtmlAnchor a1 = page.getAnchorByHref("play.php?choose=2");
    System.out.println(a1.asXml());
    HtmlAnchor a2 = page.getFirstByXPath("//a[@href='play.php?choose=2']");
    System.out.println(a2.asXml());
}
