将函数作为参数传递给递归 setTimeout
Pass function as parameter to recursive setTimeout
此代码无效:
var counter = 0;
kick(print);
function kick(f) {
setTimeout(function(){
f(); // problem here;
kick();
}, 500);
}
function print(){
console.log(counter++);
}
浏览器控制台出现以下错误:
Uncaught TypeError: f is not a function
如何在需要的地方正确调用 f()
?
再过 f
轮:
function kick(f) {
setTimeout(function(){
f(); // problem here;
kick(f);
}, 500);
}
