有三個(gè)問(wèn)題： 第一個(gè)document.write本身是輸出 類似一個(gè)功能 而你應(yīng)該是想把時(shí)間賦值給date? 所以應(yīng)該是?var date=document.write(hour + "："+minute+"："+second)? ； 第二個(gè)問(wèn)題，源代碼中這句var date=document.write(hour + "："+minute+"："+second)； 最后這個(gè)分號(hào)用的是中文分號(hào)； 第三個(gè)問(wèn)題 計(jì)時(shí)器應(yīng)該放在函數(shù)外面? 修改后就能正常運(yùn)行了：

沒(méi)有var date = document.write(hour + "：" + minute + "：" + second) 這種寫法吧
2019-07-21
<script type="text/javascript">
window.onload = function(){
var attime;
function clock() {
var time = new Date();
var hour = time.getHours();
var minute = time.getMinutes();
var second = time.getSeconds();
//var date = document.write(hour + "：" + minute + "：" + second) ;
var attime = hour + "：" + minute + "：" + second;
document.getElementById("clocks").value = "";
document.getElementById("clocks").value = attime;
setInterval(clock,1000)
}
clock()
}
</script>

沒(méi)聽懂，那是在input里調(diào)用嗎

clock函數(shù)沒(méi)調(diào)用，setInterval 那里有問(wèn)題，注意一下
