问题描述
我目前正在建立一个托管软件的网站。我想要的是添加到项目页面的是一个循环截图的幻灯片,每5秒更换一次图像。是否有任何方法可以使用JavaScript在一个时间间隔触发脚本? ..或者我将不得不采用其他方法来实现我所需的功能。
提前感谢您的帮助!
I am currently building a website to host software. What I want is to add to the project pages is a slideshow of screenshots cycling, changing images about every 5 seconds. Is there any way to a script triggered at a time interval using just JavaScript? ..or will I have to resort to alternative methods for achieving my desired functionality. Thanks in advance for any help!
推荐答案
function doSomething() {
alert('This pops up every 5 seconds and is annoying!');
}
setInterval(doSomething, 5000); // Time in milliseconds
每隔 n 重复传递你想要调用的函数>毫秒。 ( setTimeout
,顺便说一下,会调用一个超时的函数。)
Pass it the function you want called repeatedly every n milliseconds. (setTimeout
, by the way, will call a function with a timeout.)
如果你想要停止计时器,保持 setInterval
的返回值并将其传递给 clearInterval
。
If you ever want to stop the timer, hold onto setInterval
’s return value and pass it to clearInterval
.
