JavaScript Invalid Argument

RobertFoster

Hi,

Bit of a JavaScript problem with the following code:

function check(){
var username=document.signup.username.value;
var check='checkname.php?name='+username;
checkwindow=window.open(check,'name check','width=300,height=100,resizable=no,scrollbars=no,toolbar=no,location=no,status=no,menubar=no');
}

It works in firefox (insofar as it doesn't produce any errors and returns my expected results) but I get an "Error: Invalid Argument" with IE.

I've tried other variations, such as:

function check(){
var username=document.signup.username.value;
checkwindow=window.open('checkname.php?name='+username,'name check','width=300,height=100,resizable=no,scrollbars=no,toolbar=no,location=no,status=no,menubar=no');
}

with no joy.

try changing
document.signup
to
window.document.all.signup

I think you also need to have the
'width=300,height=100'
seperated by ;
'width=300;height=100'

Two options (untested, but you'll get the gist of it):

1. Add an id="username" to the username element and use: var username = document.getElementById('username').value

2. var username = document.forms("signup").elements("username").value

document.all is IE only. Its often handy to use alert()'s to debug your code, to see if you're getting expected results. Looking at it again, the error is probably being caused by the second problem outlined by the previous poster. Also I don't think spaces are valid in window names.

thank you both for the replies.

put the semi-colon in, it got the width right, but the height streched to the full height of my screen.

neither worked.
