simple example; populate textbox based on pulldown

[CFeyrer]

Can I have Javascript trigger a textfield to populate with a given value based on the content of a pulldown?
For example, if pulldown=M then textbox='Mr' if pulldown=F then textbox='Ms'

Thanks for your assistance.
PS I would love for this to work without refreshing the page/losing form data!

In your dropdown, add an onchange event:

<select onchange='updateTextBox(this.value)'>

Create a function:

<script>function updateTextBox(val)
{
 if(val == "something")
 {
  document.forms['myForm'].elements['myTextBox'].value = "something based on something";
 }
 else if(val == "something else")
 {
  document.forms['myForm'].elements['myTextBox'].value = "something based on something else";
 }
}
</script>

'make sense?

This assumes your form elements are in FORM tags and the FORM is NAMEd 'myForm' and the text box is NAMEd 'myTextBox'
