Description

I want get all checkboxes from a html page. I use window.get_elements but window.get_elements() trigger a JS TypeError. The error happens with elements selectionDirection, selectionStart and selectionEnd in the checkbox node.

A fast way to fix that are adding a try... catch in copyJSON (in js/dom.py) like

` var copyJSON = function(node, opts) {

    var copy = {};
    for (var n in node) {
        try {
            if (typeof node[n] !== "undefined" && typeof node[n] !== "function" && n.charAt(0).toLowerCase() === n.charAt(0)) {
                if (typeof node[n] !== "object" || node[n] instanceof Array) {
                    if (opts.cull) {
                        if (node[n] || node[n] === 0 || node[n] === false) {
                            copy[n] = node[n];
                        }
                    } else {
                        copy[n] = node[n];
                    }
                }
            }
        } catch {
            console.log(n);
        }
    }
    copy = boolFilter(copy, opts.domProperties);
    return copy;
};

`

But, this don't fix the bug, just hide it. But i have no idea how fix that... and if can be fixed.

An ancient version of domJSON was used. The issue is fixed by upgrading domJSON to the latest version.
The fix is committed to master.
