Paging Through Records Using jQuery

Question

I have a JSON result that contains numerous records. I\'d like to show the first one, but have a next button to view the second, and so on. I don\'t want the page to refresh

Hope this helps:

var noName = {
    data: null
    ,currentIndex : 0
    ,init: function(data) {
        this.data = data;
        this.show(this.data.length - 1); // show last
    }
    ,show: function(index) {
        var jsonObj = this.data[index];
        if(!jsonObj) {
            alert("No more data");
            return;
        }
        this.currentIndex = index;
        var title = jsonObj.title;
        var text = jsonObj.text;
        var next = $("").attr("href","#").click(this.nextHandler).text("next");
        var previous = $("").attr("href","#").click(this.previousHandler).text("previous");

        $("body").html("
"+title+"
"+text+"
");
        $("body").append(previous);
        $("body").append(document.createTextNode(" "));
        $("body").append(next);
    }
    ,nextHandler: function() {
        noName.show(noName.currentIndex + 1);
    }
    ,previousHandler: function() {
        noName.show(noName.currentIndex - 1);
    }
};

window.onload = function() {
    var data = [
        {"title": "Hello there", "text": "Some text"},
        {"title": "Another title", "text": "Other"}
    ];
    noName.init(data);
};
