Java 获取“美元”“未定义”；

我试图探索在测试中添加咆哮通知的特性。 这允许在测试执行时在屏幕上添加消息

我通过以下步骤尝试此方法：

电脑：视窗10 Selenium版本：2.53 浏览器：Firefox49

下面是我正在使用的脚本：

public class GrowlTest {

    static String JGROWL_SCRIPT = "http://cdnjs.cloudflare.com/ajax/libs/jquery-jgrowl/1.2.12/jquery.jgrowl.min.js";
    static String JQUERY_SCRIPT = "http://code.jquery.com/jquery-1.11.1.min.js";
    static String JGROWL_STYLE = "http://cdnjs.cloudflare.com/ajax/libs/jquery-jgrowl/1.2.12/jquery.jgrowl.min.css";
    static FirefoxDriver driver;
    public static void main(String [] args) throws InterruptedException
    {   


        driver =new FirefoxDriver();
        driver.manage().window().maximize();
        //waitForJStoLoad();

          driver.manage().deleteAllCookies();
          growlNotification(driver,"hi this is inital test..", "try");
          driver.get("http://www.amazon.com");
          Thread.sleep(10000);
          System.out.println("waiting for popup to come..");
          driver.findElement(By.xpath("//*[contains(text(),'Stay')]")).click();
          System.out.println("clicked on pop up..now waiting for notification...");
          Thread.sleep(10000);
          System.out.println("wait is completed..");

          growlNotification(driver,"Hi First try","first:");    
          Thread.sleep(2000);
          growlNotification(driver,"Hi second try","second:");
          Thread.sleep(2000);
          growlNotification(driver,"Hi third try","third:");
          Thread.sleep(2000);
          growlNotification(driver,"Hi fourth try","fourth:");
          Thread.sleep(2000);
          driver.quit();


        try {
            Thread.sleep(5000);
        } catch (InterruptedException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }

        try {
            Thread.sleep(2000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }   
    }
    private static void growlNotification(WebDriver driver, String msg, String header) throws InterruptedException 
    {
        FirefoxDriver js=(FirefoxDriver) driver;
        js.executeScript("if (!window.jQuery) {var jquery = document.createElement('script'); jquery.type = 'text/javascript';jquery.src = 'https://ajax.googleapis.com/ajax/libs/jquery/2.0.2/jquery.min.js';document.getElementsByTagName('head')[0].appendChild(jquery)}");
        //TODO Add check for existing jQuery on page
        js.executeScript( "var jq = document.createElement('script'); jq.type = 'text/javascript'; jq.src = '" +
        JQUERY_SCRIPT + "'; document.getElementsByTagName('head')[0].appendChild(jq);" );

        js.executeScript( "$.getScript(\"" + JGROWL_SCRIPT + "\");" );

        js.executeScript( "var lnk = document.createElement('link'); lnk.rel = 'stylesheet'; lnk.href = '" +
        JGROWL_STYLE + "'; lnk.type = 'text/css'; document.getElementsByTagName('head')[0].appendChild(lnk);" );
        js.executeScript( "$.jGrowl('" + msg + "', { header: '" + header + "' });" );
    }
}

执行此操作时，我得到以下错误：

但是，当我执行以下代码时，相同的脚本也会起作用：

请帮助并建议需要做什么

感谢和问候，

我的猜测是，在js.executeScript（）调用之间，您需要休息一会儿，以便为正在调用的javascript提供加载时间。如果你看一下，你说的works脚本在操作之间有各种休眠，可能允许加载和处理东西。

Nope…用相同的代码尝试过。它不起作用，得到相同的错误：线程“main”中出现异常org.openqa.selenium.WebDriverException:$.jGrowl不是函数命令持续时间或超时：16毫秒构建信息：版本：'2.53.0'，修订版：'35ae25b'，时间：'2016-03-15 16:57:40'我添加了所需文件1）2）3）在控制台中尝试$.jGrowl（'hi'）时工作正常。但当通过java程序执行时，我得到“$未定义”@stanlemon
