I'm trying to change the value of a text box with the the item I select from a drop down box. But it's not working.

I tried this HTML:

<select name=ncontacts id=contacts onchange=ChooseContact(this);> 

</select>

and this JS:

function ChooseContact(data)

{

   alert(data);

   document.getElementById(friendName).value = data;

}

But the text box val is not updated.

This is because this (the argument to ChooseContact) refers to the select element itself, and not its value. You need to set the value of the friendName element to the value of the select element:

document.getElementById(friendName).value = data.value; //data is the element

Here's a working example.
