Question

I need to redirect a page using JS and I wonder how to do that? Assume I have following URL already opened in the browser which has few anchor tags,

file:///someDrive:/someFolder/index.html

One of anchor tag has onclick set to redirect('login.html'); and when I press it it should redirect to,

file:///someDrive:/someFolder/login.html

How?

If you really want to have a JavaScript function, you can do:

function redirect(page) {
    var href = window.location.href;
    // this will remove "/index.html" from the URL
    var path = href.substring(0, href.lastIndexOf('/'));

    window.location.href = path + '/' + page;
    // or window.location.assign(path + '/' + page);
}

Still, for normal links, you don’t need this, setting the correct href attribute is sufficient. Also, if you don’t have a form, I would not use <input type="button" /> but just <button>^(docu).
