Can someone provide me with a function (using javascript) on how to check against a list of items...

example:

A user enters a specific value, the script will check against a list of items, if the specified value matches with any of the items in the list then the returned message would be: Welcome

If it does not match with the list, the returned value would be: rejected

Any help is appreciated.

Do you mean like a

Form Input Validation JavaScript?

Yes but not a generic one,.... not like the one that would check to see if as a field was populated with values...

what i'm looking for is a validation script that checks against a list of items as i mentioned above, and depending on the input it will provide different feedback, or direct to a specific page based on the feedback.

Well I may be on the wrong path here because all my knowledge is self taught (you only have to look at my websites to see that LOL

) but, google says:

That's done in .NET; I need a client-side code (javascript) for this.

Sorry Info....... See what I mean?
I'd assume though that you would need a database to compare the scripts inputs though, or is not the case?

What is this for? Home shopping? Database enquiries? Or am I just completely out of my depth?

How many items? Many or just a few?
Will this list change or remain static?

It's ok... I already got it...

Here is how I did it:

  <script language="JavaScript" type="text/javascript">
 function check() {
 
  var items=new Array();
  items[0]="item-1";
  items[1]="item-2";
  items[2]="item-3";
  
  input = document.getElementById("in").value;
  if(input=="") {
   alert("Please enter a value !");
   return;
  }
  
  for(i=0; i<items.length; i++)
   if( input==items ) {
    location.href = "welcome.html";
    return;
   }

  location.href = "rejected.html";
  
 }
  </script>

I told you I was out of my depth LOL

But it all sounds good anyway

I'm just pleased with myself that I can do what I do with googling and ploughing through bits and bobs, but I will never be up with you guys. I'm too old now to learn that sort of stuff, which is a shame when you have the ideas and hopes, but not the brains Ouch

haha...

I'm personally a Information Security guy... that's my major ... I do some basic web design though; and I'm also involved in the management of a few big web projects like a voice chat that a professional developer and I are doing... my role in that project is financing...testing...etc...

Sounds like a brain surgeon to me bud, but I'll take your word for it Thumbs%20Up

I run my own businesses, nothing special but it beats working for an employer

I just like learning and challenging myself on the web but I know I will never be up there with the BIG CHEESES! Ermm

But I do like our choices of avatars on our forums compared to the bog standard ones!

At least there I can pull a few more smilies! Big%20smile
