[RESOLVED] 2 bits of code i dnt know how to merge

Copy linkTweet thisAlerts:
Jul 02.2007

This:

[CODE]<input type=”text” onkeyup=”showHint if(this.value.length>3){this.value=”;alert(‘The currency code can only contain 3 letters!’);}[/CODE]

And this:

[CODE]<input type=”text” id=”txt1″
onkeyup=”showHint(this.value)”>[/CODE]

I need it so it will run the function after the 3rd letter is typed, and still display an error if more than 3 letters are typed

any idea? ?

Limit the text input to a maxlength=3. That way there is no need to use anything to alert anyone about anywhat. They can't enter more than three.

@dntelauthorJul 03.2007 — Yep, i've decided to do that, would it just be:

[CODE]<input type="text" maxlength=3>[/CODE]

And i wanted to put that function to run as well because im going to have it so when you click off the text box, its asynchronously checks a database so i need a function to run to make an XmlHttpRequest ?

any ideas?

thanks
