The use of JavaScript interrupt function setinterval ();

<script type= "Text/javascript" >
var I=1;
var IR1 = setinterval ("MyMethod ()", 1000);
function MyMethod () {
i++;
Console.debug (i);
Console.debug ("a");
if (i>20) {
Clearinterval (IR1);
}
}
</script>

Program Ideas:

1. Create an Interrupt Object

var IR = setinterval (MyMethod (), 1000);

1000 means 1s interval, 1ms per unit

2. Create callback function

int i = 1;

function MyMethod () {

i++;

}

3, in order to let each 1s output call once mymethod (), and then join the call 20 times, we need to write a good judgment in MyMethod (), if the conditions meet certain requirements, stop the interrupt, at this time, then the initial interrupt object set empty, as follows

int i = 1;

function MyMethod () {

i++;

if (i>20) {

SetInterval (IR);

}

}
