JavaScript–欧元™s setTimeout以及如何将其与方法一起使用

Posted 2021-02-26

Everything works as expected for the setTimeout() function until you try to call a method inside your ‘class’ (there are no real classes in javascript). Something like this won’t work:

setTimeout(this.methodToCall, time);
Passing a string representation instead of reference doesn’t work either.

So here is the simple solution:

thisObj = this;
setTimeout(function() { thisObj.methodToCall(); }, time);
