What are some techniques to enhance security when transmitting variables through a URL in JavaScript?

Instead of passing variables through a URL, I am considering implementing a method where the parameters are sent to the popup window through variables once it is opened. This would add an extra layer of security by not exposing sensitive information in the URL.

Another idea is to incorporate a function that runs when the link is accessed, which then transfers the necessary values to the JavaScript function within the new window. This could provide additional security measures against unauthorized access.

Is there anything else I can do to enhance the security of this process?

EDIT: To clarify, this system is internal and not intended for public use. Therefore, my main concern is ensuring that fake forms cannot be submitted using manipulated URLs.

Due to limitations with older technologies like tabular data control in IE, server-side validation or database verification is not feasible in this scenario.

Answer №1

If you want to avoid appending values to the URL, you can send them using a POST method with HTML forms. Here's an example:

<form action="derp.html" method="POST" target="myNewWindow">
    <input type="hidden" value="derp" name="name"/>
    <input type="hidden" value="derp" name="lname"/>
    <a href="#" onclick="window.open("myNewWindow");this.parentNode.submit()">Click to open in a new window</a>
</form>

Answer №2

There are two alternatives available to you

1) Instead of utilizing the GET method (which sends parameters in the URL), opt for the POST method. This way, the parameters will not be visible in the HTML URL anymore, and you can achieve this using JavaScript. However, it is still possible for malicious individuals to send fake values to your server, although it becomes slightly more challenging.

2) Develop a hash function in JavaScript that encodes all parameters before submitting the URL and decodes them upon receiving on the server side. You can learn more about hash functions here: http://en.wikipedia.org/wiki/Hash_function

Both methods do not guarantee 100% security, so it is advisable to also conduct parameter validation on the server side.

Answer №3

Transforming it into a post request is the only option available if the logic resides on the front end, besides possibly concealing the variable names.
