又遇到个蹊跷的问题
我的document.all.personinfo.innerText=str语句为什么不执行，alert(str)能顺利执行。纳闷了……
<html>
<head>
<script language="JavaScript">
function person()
{
var s=document.forms[0],name,sex,age,str;
name =s.username.value;
for( var i=0;i<s.usersex.length;i++)
{
if(s.usersex[i].checked)
sex = s.usersex[i].value;
}
age = s.userage.options[s.userage.selectedIndex].value;
str="您的个人信息为："+name+"---"+sex+"---"+age;
alert(str);
document.all.personinfo.innerText=str;
}
</script>
</HEAD>
<BODY>
<p id=personinfo></p>
<form onSubmit="person()">
<input type="text" name="username">
<input type="radio" name="usersex" value="男" checked>男
<input type="radio" name="usersex" value="女">女
<select name="userage">
<option value=18>18
<option value=20>20
<option value=22>22
<option value=24>24
</select>
<input type="submit" name="submit" value="提交">
</form>
</BODY>
</HTML>

貌似innerText是只读属性。
改成 innerHTML 试试

onSubmit="return person()"
不要再犯这样低级的错误
