How access form fields using javascript?

Question

<form name="myForm">
   <input type="text" name="f['cart']]['product_name']"/>
</form>

How can I access textfield's value using javascript?

name on <form> is a legacy attribute that only exists for backwards compatibility with truly ancient browsers. Use id instead. — Quentin

Get the form from the forms collection, then the input from said form's elements collection.

document.forms['myForm'].elements["f['cart']]['product_name']"]

My apologies, the code I was testing was embedded in a CMS which was changing the form name at run time I found. It does work perfectly.
