This is the source code in the book, I feel there is no difference! I've been depressed all day and asked for help.

<HTML><HEAD>	<Script Language="JavaScript">		function check()		{			var inst = "爱好：";			if(document.myform.txt1.value=="")			{					alert("请输入姓名！");			}			else			{				alert("姓名："+document.myform.txt1.value );				if(document.myform.sex[0].checked) alert("性别：男");				else alert("性别：女");				if(document.myform.inst[0].checked) inst += "游泳";				if(document.myform.inst[1].checked) inst += ",滑冰";				if(document.myform.inst[2].checked) inst += ",散步";				if(inst=="爱好：")					alert("赶快培养一个爱好吧！");				else					alert(inst);			}		}	</Script></HEAD><BODY>	<center>		<form name="myform">			<p>请输入您的姓名：			<input type="text" name="txt1" value="">			<p>请选择您的性别：			<p>男<input type="radio" value="男" name="sex" checked>			<p>女<input type="radio" value="女" name="sex">				<p>请选择您的爱好：			<p>游泳<input type="checkbox" value="游泳" name="inst" checked>			<p>滑冰<input type="checkbox" value="滑冰" name="inst">			<p>散步<input type="checkbox" value="散步" name="inst">			<p><input type="button" value="Click" OnClick="check()">		</form>	</center></BODY></HTML>

Solved, through BCompare software to compare the differences with the source code, it was found that if(document.myform.sex[0].checked) alert("Gender: Male"); inside the left bracket It’s Chinese parentheses, I’ll have to be more careful in the future.

/wo y haha That’s it
