i have write this code for perform simple action but not working at all
<script type="text/javascript">
var a = 10;
function add() {
window.setInterval(a2, 10000);
alert(a);
}
function a2() {
a = a + 2;
}
</script>
this alert in only returning value 10 only one time. how to achieve this working through timing and looping?
If you want more alerts, you need to put alert() in the timed function itself. Execution won't return to add() from a2().
function a2() {
a = a + 2;
alert(a);
}
Your alert instruction is out of the interval, try the code below:
<script type="text/javascript">
var a = 10;
function add() {
window.setInterval(a2, 10000);
}
function a2() {
a = a + 2;
alert(a);
}
</script>
Try this instead:
var a = 10;
window.setInterval(add, 1000);
function add() {
alert(a);
a = a + 2;
}
