Below are the means I found.

Javascript

function verificaUrl(url) {
    var http = new XMLHttpRequest();
    http.open('HEAD', url, false);
    http.send();
    return http.status != 404;
}

jQuery

$.ajax({
    url:'http://www.exemplo.com.br/arquivo.txt',
    type:'HEAD',
    success: function() {
        //arquivo existe
    }
    error: function() {
        //arquivo não existe
    },
 });
