Validate Email by Javascript then link to next page

[thupham]

I have 2 page:
index.aspx
next.aspx
and the code in javascript to validate Email:

function fnEmail() 
		{ 	
			if(checkEmail(form1.txtEmail.value)== false) 
			{
				alert("Email is not valid!");
				form1.txtEmail.focus();
				return false;
			} 
			return true; 
		} 
		 function checkEmail(mail)
		{
			mail = trim(mail);
			var re=/^[\w-]+(\.[\w-]+)*@([\w-]+\.)+[a-zA-Z]{2,4}$/
			if(mail.match(re) == null)
				return false;
			return true;
		}
		function trim(sString) 
		{
			while (sString.substring(0,1) == ' ') 
			{
				sString = sString.substring(1, sString.length);
			}
			while (sString.substring(sString.length-1, sString.length) == ' ')
			{
				sString = sString.substring(0,sString.length-1);
			}
			return sString;
		}

and the <input>:
<a id="linknext" href="next.html"><input type="button" onclick="return         fnEmail();" class="NextButton" width="56" height="27"
																					style="WIDTH: 56px; HEIGHT: 27px"> </a>

When you click in button, I want to test email valid then link to next.aspx page,
but It's not test validate and link to next.aspx? I don't know why and how to fix this bug.
Can you help me for the purpose: testing email and link to next.aspx page?.
Thanks

Thanks for your reply but the link before is only submit the content and not link to next page. You can see in example before, the <input> tag was nested in <a> tag:
<a href="next.aspx "><input type="submit" onclick="return fnEmail()"></input></a> Can you search more web you know about this problem for me?.
Thanks.
