Javascript help needed - Irish SEO, Marketing & Webmaster Discussion

I'm trying to create some dynamic form fields using javascript. Basically the user enters some text in the new_option text field below and when they click the add_option button it adds a populated text field to a form that is already on the page. Anyone know how to do this off hand?

Code:

<input type="text" name="new_option"> <input type="button" name="add_option" value="Add Option" onClick="xxxx">

When button is pressed the new_options are outputed here as addtional text fields which can then be submitted with the main form.

Edit: I've come across an example at http://www.openjs.com/scripts/examples/addfield.php that comes close to what I'm trying to do. Seems like it should work for me, just need to re-write it a bit to suit my needs.

That example is exactly what you are looking for but require small changes to get the value:

Code:

//change the function adding an extra field
function addField(field,area,limit,field_value) { 
//add value
input.value = field_value;

Thanks Louie, I've got it working peachy now (almost) after a lot of head scratching and head banging.
