AJAX Poll

The following example demonstrates a poll where the result is shown without reloading:
Which language do you like the most?

C/C++      Java      Lisp      Perl      PHP      Prolog      Python
This example consists of four pages: The HTML Form
It contains a simple HTML form and a link to a JavaScript page. 

<html>
  <head><script src="GetVote.js"></script></head>
  <body><div id="poll"><form>
    Which language do you like the most? 
    <input type="radio" name="vote" value="0"
      onClick="getVote( this.value )"> C/C++
    <input type="radio" name="vote" value="1"
      onClick="getVote( this.value )"> Java
    ...
  </form></div></body>
</html>

As you can see, the HTML page above contains a simple HTML form inside a <div> with seven radio buttons. The form works like this:
  1. An event onClick is triggered when the user selects any option.

  2. When the event is triggered, a function called getVote is executed.

  3. Around the form is a <div> called poll. When the data is returned from the getVote function, the return data will replace the form.
