        element[i].setAttribute("name", "text");
        element[i].setAttribute("placeholder",datArray[i]);
        element[i].setAttribute("id", datArray[i]+"id");
        var foo = document.getElementById("fooBar");

Are you always sending the same model Object? I mean, does your form element always has the same name attribute?

if yes, you can just create a pojo class with attributes maching your names and use a RequestAttribute annotation.

If no, there is no way, you will just have to use the old requestparameter.

UPDATE If you dont know what parameters are submitted, loop into all parameters :

    List<String> requestParameterNames = Collections.list((Enumeration<String>) request.getParameterNames());

for (String parameterName : requestParameterNames) {
    String attributeName = parameterName;
    String attributeValue = request.getParameter(parameterName);

    //DO YOUR STUFF
}
//DO YOUR STUFF
