Adding characters to input field

rmagan · Jan 13, 2004

I have a form that uses a input text field. When the user enters a value, I need to make it uppercase and add some characters to the begining and end of the field and pass it to a function.

For example: If the users enters "s1" I need to send the value of "/~S1~/" to the function.

<input type="text" name="p_chg_semester" Ssize="5" maxlength="2" onChange="IsValidSemester(this.value>);

rmagan,

Maybe this will get you started:

Code:

<html><head><title>TEST</title>
<script language=&quot;JavaScript&quot;>
function mkstr(val){
if(val.length == 2) {
out = 'Prefix'+val.toUpperCase()+'Suffix';
document.getElementById('output').value = out;}
}
</script></head><body>
<input type=&quot;text&quot; size=&quot;5&quot; onBlur=&quot;mkstr(this.value)&quot;>
<input type=&quot;text&quot; id='output' size=&quot;20&quot;>
</body></html>

Just shout back if it doesn't do what you need.
