问题描述
是否可以限制setInterval在javascript中触发的次数?
Is it possible to limit the amount of times that setInterval will fire in javascript?
推荐答案
你可以调用 x 来电:
var x = 0;
var intervalID = setInterval(function () {
// Your logic here
if (++x === 5) {
window.clearInterval(intervalID);
}
}, 1000);
为了避免全局变量,上述改进将是:
To avoid global variables, an improvement of the above would be:
function setIntervalX(callback, delay, repetitions) {
var x = 0;
var intervalID = window.setInterval(function () {
callback();
if (++x === repetitions) {
window.clearInterval(intervalID);
}
}, delay);
}
然后你可以调用新的 setInvervalX()
功能如下:
Then you can call the new setInvervalX()
function as follows:
// This will be repeated every for 5 times with 1 second intervals:
setIntervalX(function () {
// Your logic here
}, 1000, 5);
