Play *.wav or beep in javascript

[jpabich]

I have a javascript file that runs from an ASP.Net page. I need to either emit a beep or play a wav file of a beep. Can you tell me how to do that? Here is my code where I want to place it.

if (document.getElementById('hidEndAlarm').value == "1")
{
if (document.getElementById('lblTargetTime').innerText == document.getElementById('lblElapsedTime').innerText)
{
// Flash screen and beep
var Flash=0;

// PLAY BEEP HERE
}
}
