Handling AJAX controls in WebDriver

          Web applications today are being designed in such a way that they appear the same as

desktop applications. Web developers are accomplishing this by using AJAX within their web

applications. AJAX stands for Asynchronous JavaScript and XML due to the fact that it relies

on JavaScript creating asynchronous calls and then returning XML with the data that the user

or application requires to carry on. AJAX does not rely on XML anymore, as more and more

people move over JSON, JavaScript Object Notation, which is more lightweight in the way

that it transfers the data. It does not rely on the extra overhead of opening and closing tags

that is needed to create valid XML.

  Most of the time WebDriver automatically handle the Ajax controls and calls/ Incase if it is not able to handle, you can follow the below way to handle

     Method 1 :

for (int second = 0;; second++) {       if (second >= 60) fail("timeout");       try { if (isElementPresent(By.<locatorType>("<locator Value"))) break; } catch (Exception e) {}       Thread.sleep(1000);     }

Example :

    

Method 2:

//Waiting for Ajax Control     WebElement AjaxElement = (new WebDriverWait(driver, 10)).until(ExpectedConditions.presenceOfElementLocated(By. <locatorType>("<locator Value>")));

Ex :
