非常简单的php验证.
请大神给段代码吧，我知道很简单，可是我试验很多方法，不是不跳转就是原地不动。怎么也搞不出来.
就是实现：输入框写邮政编码，然后验证如果是5个数字就跳转到下一页，不是5就停留在原页并且在输入框后面添加“邮政编码不对”.
感谢各位大神.

<script><br /> function iszipcode(object)<br /> {<br /> var s =document.getElementById(object.id).value; <br /> var pattern =/^[0-9]{6}$/;<br /> if(s!="")<br /> {<br /> if(!pattern.exec(s))<br /> {<br /> alert('请输入正确的邮政编码');<br /> object.value="";<br /> object.focus();<br /> }<br /> }<br /> }<br /> <br /> </script>
