Javascript Question

loop on a function in javascript?

Can we run a loop on a function in javascript, so that the function executes several times?

Answer

if you tired of using standard like (IF, WHILE), here is the another way of doing.. :)

you can use setTimeOut and clearTimeOut to execute functions in a certain interval. If you want to execute an function for a specific number of times, you still can acheive it by incrementing index and clearTimeOut as soon as your index reaches to certain point.

setTimeout() - executes a code some time in the future

clearTimeout() - cancels the setTimeout()

example from w3schools

<html>
<head>
<script type="text/javascript">
var c=0;
var t;
var timer_is_on=0;

function timedCount()
{
document.getElementById('txt').value=c;
c=c+1;
t=setTimeout("timedCount()",1000);
}

function doTimer()
{
if (!timer_is_on)
  {
  timer_is_on=1;
  timedCount();
  }
}

function stopCount()
{
clearTimeout(t);
timer_is_on=0;
}
</script>
</head>

<body>
<form>
<input type="button" value="Start count!" onClick="doTimer()">
<input type="text" id="txt">
<input type="button" value="Stop count!" onClick="stopCount()">
</form>
</body>
</html>
