Redirect to another page

Question

I have a Dropzone.js and after dragging and dropping a file in my html I would like to receive a redirect to another page, I would like to know how to proceed, I tried some ways and could not, if someone can give me a light.

Dropzone.js

function addProgressBar(that, i, index){
    $(that.element).parent()
        .append('<div class="progress progress-'+index+'"></div>')
        .css({'margin': that.options.margin});
    $(".progress-"+index).css({
        width: that.options.progressBarWidth,
        margin: '20px 0 0 0',
    }).append('<div class="progress-bar progress-bar-info progress-bar-striped active"></div>').hide();
    $(".progress-" + index).wrap('<div class="extra-progress-wrapper"></div>');
    //$(".progress-" + index).parent().append('<span title="'+that.options.files[i].name+'">'+that.options.files[i].name.trunc(20)+'</span>').css("width", that.options.progressBarWidth);
    if(that.options.showTimer){
        $(".progress-" + index).parent().append('<span style="float:right" class="upload-timer-'+index+'">0</span>');
    }
}

function addFileToBigField(that, i, index){
    $(that.element).parent()
        .append('<div class="progress error-progress-'+index+'"></div>')
        .css('margin', that.options.margin);
    var file = that.options.files[i];
    var fileName = file.name.trunc(25);
    $(".error-progress-"+index).css({
        width: that.options.progressBarWidth,
        margin: '20px 0 0 0'
    }).append('<div class="progress-bar progress-bar-danger progress-bar-striped" style="width:100%">Arquivo muito grande ('+humanFileSize(file.size)+')</div>');
    $(".error-progress-" + index).wrap('<div class="extra-progress-wrapper"></div>').css("width", that.options.progressBarWidth);
    $(".error-progress-" + index).parent().append('<span title="'+that.options.files[i].name+'">'+fileName+'</span>');
