This example includes four elements:
① HTML form
② JavaScript
③ PHP page
④ Text file to store the results
1. HTML form
This is an HTML page. It contains a simple HTML form, and a connection to a JavaScript file:
<html> <head> <script src="poll.js"></script> </head> <body> <div id="poll"> <h2>Do you like PHP and AJAX so far?</h2> <form> Yes: <input type="radio" name="vote" value="0" onclick="getVote(this.value)"> <br /> No: <input type="radio" name="vote" value="1" onclick="getVote(this.value)"> </form> </div> </body> </html>
Example Explanation - HTML Form
As you can see , the HTML page above contains a simple HTML form with a <div> element with two radio buttons.
The form works like this:
· When the user selects "yes" or "no", an event will be triggered
· When the event is triggered, the getVote() function will be executed.
· Surrounding the form is a <div> named "poll". When data is returned from the getVote() function, the returned data replaces the form.
