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
I use jqgrid for just this purpose. Works like a charm.

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 = $("<a>").attr("href","#").click(this.nextHandler).text("next");
var previous = $("<a>").attr("href","#").click(this.previousHandler).text("previous");
$("body").html("<h2>"+title+"</h2><p>"+text+"</p>");
$("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);
};
I would personally load the json data into a global variable and page it that way. Hope you don't mind my assumptions on the context of survey data I think I remember you from yesterday.
var surveyData = "[{prop1: 'value', prop2:'value'},{prop1: 'value', prop2:'value'}]"
$.curPage = 0;
$.fn.loadQuestion = function(question) {
return this.each(function() {
$(this).empty().append(question.prop1);
// other appends for other question elements
});
}
$(document).ready(function() {
$.questions = JSON.parse(surveyData); // from the json2 library json.org
$('.questionDiv').loadQuestion($.questions[0]);
$('.nextButton').click(funciton(e) {
if ($.questions.length >= $.curPage+1)
$('.questionDiv').loadQuestion($.questions[$.curPage++]);
else
$('.questionDiv').empty().append('Finished');
});
});

I'll have to admit that @sktrdie approach of creating a whole plugin for handling the survey would be nice. IMO this method is really a path of least resistance solution.
