外面的那個(gè)setTimeout()會(huì)循環(huán)執(zhí)行嗎
<!DOCTYPE?HTML>
<html>
<head>
<meta?http-equiv="Content-Type"?content="text/html;?charset=utf-8">
<title>計(jì)時(shí)器</title>
</head>
<script?type="text/javascript">
??//var?num=0;
??function?f1(){var?num=0;startCount();}
??function?startCount()?{
????document.getElementById('count').value=num;
????num=num+1;
????setTimeout("startCount()",1000);?
??}
??setTimeout("f1()",10000);?
</script>
</head>
<body>
<form>
<input?type="text"?id="count"?/>
</form>
</body>
</html>如果是這樣的話(huà)，結(jié)果會(huì)是怎樣

setTimeout(startCount,1000) ?里面直接方法名稱(chēng) ?, ?不用雙引號(hào) , 也不用括號(hào)

會(huì)的，結(jié)果是：10秒后開(kāi)始執(zhí)行f1()
