用firefox的firebug可以查看到,并不是按照delay1,delay2,delay3这样打印的。 由于JavaScript是单线程处理任务的,而setTimeout是异步事件,延时时间为0的时候,JavaScript引擎会把异步事件立刻放到任务队列里,而不是立刻执行,需要等到前面处于等待状态的事件处理程序全部执行完成后再调用它(JavaScript engines only have a si...
Times will come when you might want to get a piece of code in JavScript executed after a certain amount of time frame. For instance you might want to delay a subscription pop up box on your blog for about 1 minute from the time the page completely loads. In such cases we can use th...
不，正确的行应该是setTimeout(myFn, 20000);在您的代码中，您实际上是在同一行上无延迟地调用myFn...
第一块代码大概执行了18ms,也就是JavaScript的主体代码,在执行过程中,先触发了一个setTimeout函数,代码继续执行,只等10ms后响应setTimeout的回调,接着是一个鼠标点击事件,该事件有个回调(或许是alert一些东西),不能立即执行(单线程),因为js主体代码还没执行完,所以这个回调被插入执行队列中,等待执行;接着setInter...
var id = setInterval(fn, delay); - 与setTimeout类似,只不过它会持续地调用指定的函数(每次都有一个延时),直到timer被取消为止。 clearInterval(id);, clearTimeout(id); - 接受一个timer的ID(由上述的两个函数返回的),并且停止timer的回调事件。
setTimeout(func, delay, args):设置超时调用。如对于setTimeout(func, 100, args),js引擎会为func函数设置一个计时器,100毫秒后,将func添加到任务队列等待执行。 setInterval(func, interval, args):设置循环调用。对于语句setInterval(func, 100, args),js引擎每隔100毫秒就会把func添加到任务队列一次。

Rather than loading your javascript on-demand (which can cause a noticeable gap),load your script in the background, after a delay. Use something like var delay = 5; setTimeout("loadExtraFiles();", delay * 1000); This will callloadExtraFiles()after 5 seconds, which should load the file...
