WebDriver ждать JQuery, чтобы закончить

Question

Я использую WebDriver в Java и у меня есть настроенный метод ждать DOM событий (по JQuery):

public void waitForJQuery(WebDriver driver) { 
(new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() { 
    public Boolean apply(WebDriver d) { 
    JavascriptExecutor js = (JavascriptExecutor) d; 
    return (Boolean) js.executeScript("return jQuery.active == 0"); 
    } 
}); 
} 

Когда этот метод удара по испытанию и ошибкам выбрасываются as:

org.openqa.selenium.WebDriverException: jQuery is not defined

Не могли бы вы помочь мне решить эту проблему?

Спасибо.

Answer 1

Вы можете просто добавить проверку, чтобы увидеть, если jQuery определяется первым, так что он не будет бросать исключение:

public void waitForJQuery(WebDriver driver) { 
    (new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() { 
     public Boolean apply(WebDriver d) { 
      JavascriptExecutor js = (JavascriptExecutor) d; 
      return (Boolean) js.executeScript("return !!window.jQuery && window.jQuery.active == 0"); 
     } 
    }); 
} 

Answer 2

Это, как я, наконец, получил его на работу (с некоторым выходом печати для отладки).

Адаптированный здесь:

http://pastebin.com/3uMWQ5L0

private static void waitForPageLoad(WebDriver driver) { 
    System.out.println("Wating for ready state complete"); 
    (new WebDriverWait(driver, 5)).until(new ExpectedCondition<Boolean>() { 
     public Boolean apply(WebDriver d) { 
      JavascriptExecutor js = (JavascriptExecutor) d; 
      String readyState = js.executeScript("return document.readyState").toString(); 
      System.out.println("Ready State: " + readyState); 
      return (Boolean) readyState.equals("complete"); 
     } 
    }); 
} 

Debug Output:

Wating for ready state complete 
Ready State: interactive 
Ready State: interactive 
Ready State: complete 

Для JQuery просто заменить "return document.readyState" с "return !!window.jQuery && window.jQuery.active == 0", а затем изменить оператор возврата к return (Boolean) readyState.equals("true");

Здесь код JQuery Без информации Debug (менее запутанной, я надеюсь).

private static void waitForJQuery(PhantomJSDriver driver) { 
    (new WebDriverWait(driver, 5)).until(new ExpectedCondition<Boolean>() { 
     public Boolean apply(WebDriver d) { 
      JavascriptExecutor js = (JavascriptExecutor) d; 
      return (Boolean) js.executeScript("return !!window.jQuery && window.jQuery.active == 0"); 
     } 
    }); 
}
