Enter Key Calls Function

I have a javascript function that checks that a text box has 3 characters or more and then submits the form.

The problem I have is that if you hit the enter key the javascript is ignored.

How can I call the javascript function when the enter key is pressed?

Cheers

Jemes

Code:


<SCRIPT LANGUAGE="JavaScript">

function sendtheform() {
	if (document.getElementById('txtsearch').value.length   < 3) 
        	 {
		 		document.getElementById('txtsearch').focus()
         		alert("Please enter a search that's at least 3 characters long")
        	 }
	else{
		document.getElementById('search').submit();
		}
	}
</SCRIPT>


<form ID="Search" name="Search" action="../search.asp" method="post" class="searchform">

		  <input id="txtsearch" name="txtsearch" type="text" value="<%=request.form("txtsearch")%>" size="16">&nbsp;
          <a href="javascript: sendtheform()"><img src="../images/search_Button.jpg" border="0" align="absmiddle"></a>    

	</form>
