The length property represents the number of elements within a form.
This property works the same as the elements.length property.
<html> <head> <title> Using the length property of the Form object</title> </head> <body> <script language="JavaScript"> <!-- function showNumElements(){ alert("There are " + document.form1.length + " elements in this document"); } --> </script> <form name="form1"> Enter First Name: <input type="text" size=15><br> Enter Last Name: <input type="text" size=20><br> Enter address: <input type="text" size=40><br><br> <input type="button" value="Submit" onClick=showNumElements()> </form> </body> </html>
