Hello,

 

If a box is left blank and the user tries to submit, I want to make a popup say something like 'the field was left blank'

 

Here is what I used:

 

<script type="text/javascript" language="JavaScript">
function nameempty()
{
        if ( document.login.name.value == '' )
        {
                alert('No name was entered!')
                return false;
        }
}
</script>

 

And for the submit button:

 

<form method="post" action="">
<input type="password" onkeypress="return bar(event)" name="pswd">
<br><input type="submit" type="button" name="login" value="Login" onSubmit="return nameempty();"></form>

 

For some reason, it isn't working, could someone please advise me,

 

Many thanks,

 

James

the form isn't named login, there is no "name" field, however, name is also an attribute which can be placed on all elements which means that you shouldn't name your FIELD "name", which will lead to (almost guaranteed) cross browser issues.

 

for best results, just issue an ID and use document.getElementById();
