Handling AJAX calls is one of the common issues when using Selenium WebDriver. We wouldn’t know when the AJAX call would get completed and the page has been updated. In this post, we see how to handle AJAX calls using Selenium.
AJAX stands for Asynchronous JavaScript and XML. AJAX allows the web page to retrieve small amounts of data from the server without reloading the entire page. AJAX sends HTTP requests from the client to server and then process the server’s response without reloading the entire page. To handle AJAX controls, wait commands may not work. It’s just because the actual page is not going to refresh.
When you click on a submit button, the required information may appear on the web page without refreshing the browser. Sometimes it may load in a second and sometimes it may take longer. We have no control over loading time. The best approach to handle this kind of situations in selenium is to use dynamic waits (i.e. WebDriverWait in combination with ExpectedCondition)
Some of the methods which are available are as follows:
1. titleIs() – The expected condition waits for a page with a specific title.
wait.until(ExpectedConditions.titleIs(“Deal of the Day”));
1
wait.until(ExpectedConditions.titleIs(“Deal of the Day”));
2. elementToBeClickable() – The expected condition waits for an element to be clickable i.e. it should be present/displayed/visible on the screen as well as enabled.
wait.until(ExpectedConditions.elementToBeClickable(By.xpath("xpath")));
1
wait.until(ExpectedConditions.elementToBeClickable(By.xpath("xpath")));
3. alertIsPresent() – The expected condition waits for an alert box to appear.
wait.until(ExpectedConditions.alertIsPresent()) !=null);
1
wait.until(ExpectedConditions.alertIsPresent()) !=null);
4. textToBePresentInElement() – The expected condition waits for an element having a certain string pattern.
wait.until(ExpectedConditions.textToBePresentInElement(By.id(“title’”), “text to be found”));
1
wait.until(ExpectedConditions.textToBePresentInElement(By.id(“title’”), “text to be found”));
