How to work on pages with AJAX in selenium?

Working on pages with AJAX

• Asynchronous JavaScript and XML
• AJAX is not a new programming language, but a new way to use 
• existing standards.
• AJAX is the art of exchanging data with a server, and update parts of 
• a web page – without reloading the whole page.
• AJAX is a technique for creating fast and dynamic web pages. 

Start Selenium IDE
Record some steps – run the script. It fails some where then,

• Right-click on the step that failed so that the Selenium IDE context menu 
• appears.
• Click on Insert New Command.
• In the Command select box, type waitForElementPresent or select it from 
• the drop-down list.
• In the Target box, add the target that is used in the verifyText command.
• Run the test again, and it should pass this time

The following commands make up the waitFor set of commands, but this is not an exhaustive list:
       waitForAlertNotPresent
       waitForAlertPresent
       waitForElementPresent
       waitForElementNotPresent waitForTextPresent
       waitForTextNotPresent
       waitForPageToLoad
       waitForFrameToLoad
