Hi, Can anybody tell me how to implement audio captcha using richfaces and jsf. I have already implemented captcha but now I want to implement audio functionality for visually challanged people. There should be a sound icon on click of which it should read out the captcha text generated dynamically everytime.
I got a java script code which is incomplete and I didnt understand completely as how to call this function.Code:
<body bgcolor="lightblue" onload="Init()">
<script language="JavaScript">
function Init(){
document.getElementById('userAnswer').value="";
}
var onWindows=true;
var onExplorer=true;
if(navigator.platform.indexOf("win")==-1)
{
onWindows=false;
}
if(navigator.appName !="Microsoft Internet Explorer")
{
onExplorer=false;
}
// grab user key press//
document.onkeyup=KeyCheck;
function KeyCheck(e)
{
var keyPressed=(window.event) ? event.keyCode:e.keyCode;
var hotKey=80;//p key
if(keyPressed==hotKey)
{
document.getElementById('userAnswer').value=" ";
if(onWindows and onExplorer)
{
document.getElementById('mediaPlayer').controls.play();
}
else
{
document.getElementById('writeHere').innerHTML=
'<iframe src="./playSound.php" width="0" height="0"></iframe>';
}
document.getElementById('userAnswer').focus();
}
}
/* if using IE on windows then use embeded window media player*/
</script>
