How can I get the value of an HTML form to pass to JavaScript?
Is this correct? My script takes two arguments one from textbox, one from the dropdown box.
<body>
<form name="valform" action="" method="POST">
Credit Card Validation: <input type="text" id="cctextboxid" name="cctextbox"><br/>
Card Type: <select name="cardtype" id="cardtypeid">
<option value="visa">Visa</option>
<option value="mastercard">MasterCard</option>
<option value="discover">Discover</option>
<option value="amex">Amex</option>
<option value="diners">Diners Club</option>
</select><br/>
<input type="button" name="submit" value="Verify Credit Card" onclick="isValidCreditCard(document.getElementById('cctextboxid').value,document.getElementById('cardtypeid').value)" />
</body>
