JavaScript - jQuery间隔 [英] JavaScript - jQuery interval
问题描述
我在jQuery中使用JavaScript。我有以下脚本每隔30秒警告 hi
。
I am using JavaScript with jQuery. I have the following script to alert hi
every 30 seconds.
$(document).ready( function() {
alert("hi");
setInterval(function() {
alert("hi");
}, 30000);
});
我想提醒 hi
页面时加载(文档/页面完全加载时)和之后每隔30秒(如 hi
(0s) - hi
(30s) - hi
(60s)..等)。但我的解决方案适用于两个实例。一个在DOM准备好,另一个在循环中。有没有办法在单个实例中做同样的事情?
I want to alert hi
when the page loads (when document / page gets completely loaded) and on every 30 seconds interval afterwards (like hi
(0s) - hi
(30s) - hi
(60s).. etc). But my solution works on two instances. One on DOM ready and the other in a loop. Is there any way to do the same in a single instance?

推荐答案
您可以使用setTimeout代替并让回调重新安排。
You could use setTimeout instead and have the callback reschedule itself.
$(function() {
sayHi();
function sayHi() {
setTimeout(sayHi,30000);
alert('hi');
}
});
