Question

setTimeout执行不成功

function removeImg(obj){
setTimeout(document.body.removeChild(obj),1000)
}

我想在1秒后移除摸个元素，这样写对吗

Answer 1

setTimeout是延迟执行，只执行一次，不是定时器多次间断执行要用setIntervalvar timer = setInterval( function(){}, 1000); 取消用clearInterval(timer);

Answer 2

function removeImg(obj){
setTimeout(function(){
document.body.removeChild(obj)
},1000);
}
