Is there a way to transfer the JavaScript function variable value to a Mason variable?

Question

Is there a way to transfer the JavaScript function variable value to a Mason variable?

After clicking a button on the client side, I am storing the window.location.href property in a JavaScript variable. Now, I need to send this variable back to the server. How can I retrieve the value of the JavaScript variable in Mason code?

Currently, I have implemented one option where I dynamically create a hidden text field with the value set to window.location.href, and then initiate a form submit.

My question is, how can I use ajax instead of form.submit()? I'm seeking an ajax solution and would like to understand the difference between using ajax and form.submit().

javascript ajax perl form-submit mason

The main issue at hand is that JavaScript variables are accessible to the browser's JS interpreter, not the server-side script. In order to send the variable contents back to the server, you will need to find a way to do so. This can be achieved through either using a form (which will typically require a page reload) or through XHR (the primary technology behind AJAX).

Although I personally haven't directly used XHR, with the assistance of the Dojo framework, the code might resemble something like this:

dojo.xhrPost( {
    handleAs: "json",
    url:      "http://example.com/whatever",
    content:  { "data_url" : window.location.href }
});
