Hi All,

I am able to overcome this kind of script on my studies. Hope u can help me interpret it:

The code is as follows:

[CODE]
<form name=”a” action=”javascript:b()”>
<input type=”password” name=”c” maxlength=”20″ size=”14″>
<p><input type=”submit” value=” login “>

</i></center></noscript>

<script language=JavaScript>
function b(){document.location.href=”http://academy.dyndns.org/nine/”+document.a.c.value+”.htm”;
}
</script>

[/CODE]

I am new with javascript but trying to learn it though.

Any help will be greately valued.

–david

@javaNoobieSep 03.2004 — simply redirects you to whatever page you have entered in the password field upon submission of form.

eg.if you typed 'whatever', it will redirect to http://academy.dyndns.org/nine/whatever.htm. if you typed 'somepage', it will redirect to http://academy.dyndns.org/nine/somepage.htm

<form name="a" action="java script:b()">

[/b][/quote]
a form by the name of 'a'. action refers to the page where the form is to be submitted. in this case upon submission, form will call a js function called 'b'
[b]<input type="password" name="c" maxlength="20" size="14">[/b][/quote]
textbox of name 'c', type='password' means whatever is typed inside will be masked, maxlength refers to the max number of chars you can type, size refers to the size of the textbox
[b]<p><input type="submit" value=" login ">[/b][/quote]
button when clicked submits the form.
[b]</i></center></noscript>[/b][/quote]
nothing related to the script. Just closing tags.
[b]<script language=JavaScript>[/b][/quote]
opening script tag to hold the script
[b]function b()[/b][/quote]
creation of a function called 'b'
[b]{document.location.href="http://academy.dyndns.org/nine/"+document.a.c.value+".htm";[/b][/quote]
does redirecting. in this case it will redirect to http://academy.dyndns.org/nine/<document.a.c.value>.htm. document.a.c.value refers to the textbox name 'c' in the form by the name of 'a'
[b] }[/b][/quote]
closing brace for the function
[b]</script>[/b][/quote]
closing script tag

@KorSep 03.2004 — Mybe it would have been a better ideea to use [b]onsubmit[/b] as an event handler and [b]action[/b] as attribute:

<form name="a" action="" onsubmit="b(this)")>

<input type="password" name="c" maxlength="20" size="14">

<p><input type="submit" value=" login ">

and

<script type="text/javascript">

function b(f){

f.action='http://academy.dyndns.org/nine/'+f.c.value+'.htm';

}

</script>

Success!
