Dear Experts,

I would like to ask html question about user input  number in input box to
link href or URL according to the input number change in html. How to change URL from input box with enter keys
and with  submit button. Hope you can provide two method simple code.
Frr example, if I input product no=666789 , the href link will go to web search
http://www.mywbsite.com/666789.htm

Please advise

Duncan

<body>
<form method="get" action="http:/www.mywebsite.com/#myvariable#.htm">
ProductNO: <input type="text" name="myvariable" value="">

<html>
<head>

<script language="Javascript">
<!--

function passtourl(){

var frm = document.FormName

var t1value = frm.myvariable.value

frm.action = "http:/www.mywebsite.com?myvariable=" + value
frm.submit()

}

//-->
</script>

</head>

<body>

<form name="FormName" method="Post">
<input type="text" name="myvariable" ><br>
