rated 0 times [ 3] [ 2] / answers: 1 / hits: 30988 / 12 Years ago, tue, january 29, 2013, 12:00:00

I have a simple form like this:

<form method=post id=login>



Username: <input type=text value= name=usr />

Password: <input type=password value= name=pw/>

<input type=submit id=log name=log value=Login style=width:250px;/><br/>



</form>

But i keep getting cannot read property for my javascript with this line:

var usr = login.usr.value;

var pw = login.pw.value;

What is the reason i get this error ?

Try to give your form a name and change your code like below :

<form method=post id=login name=login>



Username: <input type=text value= name=usr />

Password: <input type=password value= name=pw/>

<input type=submit id=log name=log value=Login style=width:250px;/><br/>



</form>

and the in your javascript :

var usr = document.login.usr.value;
