Example that compares using DOM and the getElementById method
<html> <head> <script type="text/javascript"> function displayResult() { alert( "Name is " + document.myForm.txtFName.value + " " + document.getElementById("txtLName").value); } </script> </head> <body> <form name="myForm"> <p>Enter Your Firstname:<input type="text" name="txtFName" value="" /><br /> Enter Your Lastname:<input type="text" id="txtLName" value="" /></p> <p><button type="button" onclick="displayResult()">Display Name</button></p> </form> </body> </html>
Note the difference between input attribute name and id.
