Stop setInterval call in JavaScript
I am using setInterval(fname, 10000); to call a function every 10 seconds in JavaScript. Is it possible to stop calling it on some event?
I want the user to be able to stop the repeated refresh of data.
setInterval() returns an interval ID, which you can pass to clearInterval() :
var refreshIntervalId = setInterval(fname, 10000);
/* later */
clearInterval(refreshIntervalId);
See the docs for setInterval() and clearInterval() .
如果将setInterval的返回值设置为变量，则可以使用clearInterval将其停止。
var myTimer = setInterval(...);
clearInterval(myTimer);
You can set a new variable and have it incremented by ++ (count up one) every time it runs, then I use a conditional statement to end it:
var intervalId = null;
var varCounter = 0;
var varName = function(){
if(varCounter <= 10) {
varCounter++;
/* your code goes here */
} else {
clearInterval(intervalId);
}
};
$(document).ready(function(){
intervalId = setInterval(varName, 10000);
});
I hope that it helps and it is right.
