这次聊的算是老生常谈的问题了,很久以前就知道setInterval存在这个问题,当时也各种 stackoverflow 不过具体忘记咋处理的了。现在又突然遇到setInterval反复执行越来越快这种情况,顺便记录下。 JavaScript 定时器 setInterval 模拟一个错误使用setinterval场景 代码语言:javascript 代码运行次数:0 运行 AI代码解释 vartimer,...
Well, for one thing you don't need to keep remembering to callsetTimeout()at the end of your timed function. Also, when usingsetInterval()there's virtually no delay between one triggering of the expression and the next. WithsetTimeout(), there's a relatively long delay while the expres...
另外,我还看到了下面这种用法,缺省了 delay 这个参数,不知道会是一个什么状态,待探究。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 // jquery 1.9.1ready:function(wait){...// Make sure body exists, at least, in case IE gets a little overzealous (ticket #5443).if(!document.body){retu...
delay3();</script> 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 ...
setTimeout and setInterval are fundamentally different in how they execute asynchronous code. If a timer is blocked from immediately executing it will be delayed until the next possible point of execution (which will be longer than the desired delay). ...
As per the title. After X seconds (similar to Flying scripts https://wordpress.org/plugins/flying-scripts) It would be nice to set a timeout of when to load the delayed scripts without physical page interaction.
setTimeout(callbackFunction, delayInMs) Creates a new timeout. setTimeouttakes two arguments, the first one is the function to call after waiting, the second one is the time in milliseconds to wait before executing the function. It returns anunsigned shortid of the timeout. If thetimeout...
实现动画效果的方法比较多,Javascript 中可以通过定时器 setTimeout 来实现,css3 可以使用 transition 和 animation 来实现,html5 中的 canvas 也可以实现。除此之外,html5 还提供一个专门用于请求动画的API,那就是 requestAnimationFrame,顾名思义就是请求动画帧。
