ok, this isnt working, i mean, it works fine unless the user doesnt enter in the right username and/or password. it simply keeps displaying the alert.... just run the script and you will see what i mean


<script language=&quot;javascript&quot;>
<!--
var usrnm=&quot;user&quot;;
var pswrd=&quot;89563&quot;;
function login()
{
var usrnmtry=window.prompt(&quot;Plz enter your user name&quot;,&quot;John Doe&quot;);
var pswrdtry=window.prompt(&quot;Plz enter your password&quot;,&quot;mightyman&quot;);

while ((usrnmtry != usrnm) &amp;&amp; (pswrdtry != pswrd))
{
window.alert(&quot;Wrong username and/or password. Plz check your information, and try
again.&quot;);
usrnmtry;
pswrdtry;
}
}
//-->
</script>
<body onLoad=&quot;login()&quot;>

maybe this will work:

var usrnm=&quot;user&quot;;
var pswrd=&quot;89563&quot;;
function login()
{
var usrnmtry=window.prompt(&quot;Plz enter your user name&quot;,&quot;John Doe&quot;);
var pswrdtry=window.prompt(&quot;Plz enter your password&quot;,&quot;mightyman&quot;);

while ((usrnmtry != usrnm) &amp;&amp; (pswrdtry != pswrd))
{
window.alert(&quot;Wrong username and/or password. Plz check your information, and try again.&quot;);
usrnmtry=window.prompt(&quot;Plz enter your user name&quot;,&quot;John Doe&quot;);
pswrdtry=window.prompt(&quot;Plz enter your password&quot;,&quot;mightyman&quot;);

Yeah, one thing to make sure of is that when using a loop of any sort, you always update the test condition. Endless loops suck! And so does slavery, and abortion, and drugs and other stuff (forward all arguments to garbagedump@mail.com) jared@aauser.com

well, gee, estesflyer, you had a problem about getting stuck in an infinite loop, and from the code you were using, it looks like you wanted to use if instead. i've seen that you want to learn javascript... that's why i didn't bother going ahead and writing a script for you, and gave you a suggestion as to where you might want to look to fix your script. from the look of your code, it looked like you were using while for no reason. so, i suggested you to use if. sorry if that wasn't what you were looking for. adam@aauser.com

I hope that you plan on using this script for a secure site.
If so, I suggest you get into a server side language (perl, php, asp, etc) because you will have anyone who knows how to look at the source of your page able to enter the intended page.

You will find many people, including myself, willing to help you with learning a server side language.
