Extracting the values of all forms on the page

This is a simple piece of javascript intended to be run from Firebug or as a bookmarklet which extracts all the name : value pairs from forms on the page and pops up a new window listing them.

It's not very well written, and doesn't yet handle any non input form elements, but it will do for now. :-)



var displayWindow = window.open();



function showFormValues(form ) { 

    displayWindow.document.write('Form:');

    displayWindow.document.write(form.name);

    displayWindow.document.write('
');



    var formElements = form.getElementsByTagName('input');



    for (var i = 0; i < formElements.length; i++){

        var element = formElements[i];

        

        displayWindow.document.write(element.name + ' :  ' + element.value + ' 
');}} 



Array.forEach(document.forms, showFormValues);
