function checkStrength(){	var stength=document.getElementById("strength");	var psw1=document.getElementById("psw1").value;	var length=psw1.length;	if(length>=1&&length<3){		strength.innerHTML="弱";//这里innerHTML,中间不要点	}if(length>=3&&length<6){		strength.innerHTML="中";	}else{		strength.innerHTML="强";	}}


你的代码使用的很多html5的技术,有些游览器是不支持的,
另外
click事件写成
onclick="return reg()"

reg方法里面校验不成功的,return false 最后返回 returnttrue

因为 type="submit"在执行完onclick后是进行表单提交的
