Example of creating an alternative custom navigation
External navigation: Prev Next Complete
Go to page directly without validation:

    document.getElementById('surveyComplete').style.display = survey.isLastPage ? "inline" : "none";
    document.getElementById('surveyProgress').innerText = "Page " + (survey.currentPageNo + 1) + " of " + survey.visiblePageCount + ".";
    if(document.getElementById('surveyPageNo')) document.getElementById('surveyPageNo').value = survey.currentPageNo;
}

survey.onCurrentPageChanged.add(function (sender, options) {
    var survey = sender;
    var oldCurrentPage = options.oldCurrentPage;
    var newCurrentPage = options.newCurrentPage;
    //Your code
});
//Requires for knockout platoform only
survey.onRendered.add(function (sender) {
    var survey = sender;
    //Your code
});
