[selenium-users] How to wait dynamically until the progress bar to load completely in Selenium WebDriver?

I think you can get a reference to the loading progress bar. Then you can
put a try/catch poll on it. When the element turns stale, is when it goes
off the screen.

waitForProgressBarToDisappear() {
   WebElement progressBar = ...;
   while(true) {
     try {
        if (progressBar.isDisplayed())
           return True;
     } catch (StaleElementException) {
        return true;
     }
    sleep(1000);
   }
}

another approach if your web app uses jQuery. jQuery has different queues
you can poll on. There's an animations queue, if you want to poll if the
progress bar is still moving, and there's and Ajax queue, if you want to
check how many outstanding requests there are waiting to return. Both are
very helpful for working with responsive single page Ajax applications.

Hi,
    You can use jquery to solve this problem.
below is the code

public boolean waitForJQueryProcessing(WebDriver driver,
             int timeOutInSeconds) {
         boolean jQcondition = false;
         try {
             driver.manage().timeouts().implicitlyWait(0, TimeUnit.SECONDS);
// nullify

// implicitlyWait()
             new WebDriverWait(driver, timeOutInSeconds) {
             }.until(new ExpectedCondition<Boolean>() {

                 @Override
                 public Boolean apply(WebDriver driverObject) {
                     return (Boolean) ((JavascriptExecutor) driverObject)
                             .executeScript("return jQuery.active == 0");

                 }
             });
             jQcondition = (Boolean) ((JavascriptExecutor) driver)
                     .executeScript("return jQuery.active == 0");
             System.out.println(jQcondition);
             driver.manage().timeouts().implicitlyWait(120,
TimeUnit.SECONDS); // reset

     // implicitlyWait
             return jQcondition;
         } catch (Exception e) {
             e.printStackTrace();
         }
         return jQcondition;
     }

}
