Example text

Php asynchronously. The text entered by the user is passed as a query string parameter (it is passed through GET). The handleServerResponse() function is designed to handle request state changes. 4. php executes on the server. It composes an XML document that encapsulates the message the server wants to send back to the client. 5. The handleServerResponse() method on the client is executed multiple times as the state of the request changes. The last time it's called is when the response has been successfully received.

However, the service can't be used to check pages with elements generated by JavaScript. The Validator service, just like web search engines, doesn't execute the JavaScript code on the page, so it can't see any content that is generated dynamically. (The page can be validated with the Web Developer Firefox addon that works with the generated HTML, which, in this case, includes the Hello world! ) [ 37 ] This material is copyright and is licensed for the sole use by ALESSANDRO CAROLLO on 18th December 2009 6393 south jamaica court, , englewood, , 80111 JavaScript and the AJAX Client The debate on standards seems to be an endless one, with one group of people being very passionate about strictly following the standards, while others are just interested in their pages looking good on a certain set of browsers.

One of the problems with the example is that you have no control in the JavaScript code over where the output should be displayed. Needless to say, this is a bit disconcerting and rather awkward. Except for the most simple of cases, having just JavaScript code that executes unconditionally when the HTML page loads isn't going to work well for you. Usually you'll want to have more control over when, where, and how portions of JavaScript code execute. The most typical scenario uses JavaScript functions that execute in response to certain events being triggered (such as clicking on a button).
