I get this error on IE9 (works fine on Chrome):

SCRIPT5007 : Unable to get the property value "remove": null object or undefined

SCRIPT5007 : Unable to get the property value "add": null object or undefined

    isValid: function (input) {
    //check required field
    if (input.getAttribute('required') != null && input.value ==="") {
        input.classList.add('error'); //add class error
        input.nextSibling.textContent = this.props.messageEmail; // show error message
        return false;
    }
    else {
        input.classList.remove('error');
        input.nextSibling.textContent = "";

        //rest of the file...

    }

The ClassList API was only introduced to IE in V10.

You could think about using a polyfill, like the one here > https://github.com/eligrey/classList.js/
