exiting setInterval method in javascript
提问by Udanesh N
i have a setInterval() function which is used as follows
我有一个 setInterval() 函数，它的用法如下
setInterval(function(){
if(window.document.drops.isFinished()){
//I want to exit the setInterval() on executing this if
}
},1000);
or tell me what is the method to exit.(In java we use System.exit(0))
或者告诉我退出的方法是什么。（在java中我们使用System.exit(0)）
回答by nicosantangelo
var timerId = setInterval(function(){
if(window.document.drops.isFinished()){
clearInterval(timerId);
}
},1000);
If the ifit's not the last thing in the function and you want to "break" the execution, maybe you want to also add a return;statement after the clearInterval.
如果if它不是函数中的最后一件事并且您想“中断”执行，也许您还想return;在clearInterval.
