request.getParameter on

Question

I current have some instances of input buttons and use request.getParameter to the request when the button is clicked. Like this:

<input type ="submit" name="test" value="test"/>

String t = request.getParameter("test");
    if (t != null) {
        System.out.print("k");
    }

I was wondering if there is a similar method for submitting data from a link , but I have not seen to come across any. In other words, I want to use a link instead for for the same result.

The application use servlets and the method="get" to handle the submit.

If you want to send the parameters through GET, then you should send them as query parameters, like: ?key1=value1&key2=value2 .

For your use case, it should work if you replace the input type with the anchor element:

<a href="/your-path?test=value">link</a>

As a side note, just make sure that you understand the difference between GET and POST. Some notes here , or simply Google it. What you've tried, with the input submit element should be handled via POST, it's really strange that it even worked in the first place.
