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

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

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
