In modern browsers (and IE8), you can use document.querySelector to use any CSS selector to find an element.

In your case, for instance, you could use

var x = document.querySelector('[action="form_action.asp"]');

…to look it up by the value of its action attribute. The rest of your function doesn’t change.

querySelector finds the first matching element. If you want a list of all matching elements, you can use querySelectorAll. In your case, for instance, if you want a list of the input elements inside the form, you could do this:

var elements = document.querySelectorAll('[action="form_action.asp"] input');

e.g.:

function myFunction() {
    var elements = document.querySelectorAll('[action="form_action.asp"] input');
    var text = "";
    var i;
    for (i = 0; i < elements.length ;i++) {
        text += elements[i].value + "<br>";
    }
    document.getElementById("demo").innerHTML = text;
}
