    I am assuming you have other elements with each respective name elsewhere in your code otherwise you can name the textboxes without the [].

    Anyway, you can use

    var myTextboxes = document.getElementsByName("txtInput[]");
    to get an array of the textboxes for a given name and then you loop through each element in the array myTextboxes and validate it for whatever you need to check.
