How to submit to different page based on Text Field Answer?

[Phil Berkey]

Basically I'm trying to have a promotional code
text field in a html form. If the correct promotional code is entered in the field the form would link to example1.html upon submission. If no code is given then the form would link to example2.html. upon submission.

Any help would be appreciated.

In the HTML form tag don't specify the action url. Add a method for onsubmit in the form. In the function check the value of the text and if it equals to ur desired one set the correct url for action attribute otherwise the other url.

Sample HTML:

<form id="myForm" name="myForm" method="post" onsubmit="checkThis()">
<input type="text" id="myText" name="myText" />
</form>

JS

function checkThis(){
  var val = document.getElementById('myText').value;
  var myForm = document.getElementById('myForm');
  if(val=="myDesiredValue")
    myForm.action="url1.html";
  else
    myForm.action="url2.html";
}

That was SUPER helpful Ramanan Kalirajan.

3 minor questions.

1. Will the form still send its contents via email if I insert the action=""?

2. How would I properly add additional promo codes?

3. Can the function verify if codes are correct or not?

Thanks for you help!

For the Questions

1) Are you using mail to in the action attribute? otherwise it will be a normal HTTP submission only.

2) You can have n no of input boxes or select boxes inside the form. That way you can add promo codes

3) Yes you can verify it in the code.
