在JavaScript中,我们经常要用到Timer,也就是setTimeout或者setInterval这两个方法。例如: 1 2 3 vart1 = setTimeout(function() { //TODO: add your logic here }, 1000); 同时,我们也经常听到有人报怨说里面的这个回调方法不支持参数传递。有时候,我们想要在里面的function里面用到外部的数据时,只能在外面...
JavaScript clearInterval() As you have seen in the above example, the program executes a block of code at every specified time interval. If you want to stop this function call, then you can use theclearInterval()method. The syntax ofclearInterval()method is: ...
