[Solved] How to get the

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;
}
