I have really been searching for almost 2 hours and have yet to find a good example on how to pass JSON data from PHP to JS. I have a JSON encoding script in PHP that echoes out a JSON script that looks more or less like this (pseudocode).
{
"1": [
{"id":"2","type":"1","description":"Foo","options:[
{"opt_id":"1","opt_desc":"Bar"},
{"opt_id":"2","opt_desc":"Lorem"}],
{"id":"3","type":"3","description":"Ipsum","options:[
...
"6":
{"id":"14","type":"1","description":"Test","options:[
...
etc
Problem is, how can I get this data with JavaScript? My goal is to make a .js script that generates a poll based on these JSON datas, but I honest to god can't find any examples on how to do this. Guessing it is some something like:
Obj jsonData = new Object();
jsonData = $.getJson('url',data,function()){
enter code here
}
Any links to any good examples or similar would be highly appreciated. And I thought that encoding the data in PHP was the tricky part...
EDIT:
I got this code snippet to work, so I can review my whole JSON data in JS. But now I can't seem to figure out how to get to the inner data. It does print out the stage number (1-6) but I can't figure out how to get the question data, and then again the options data within each question. Do I have to experiment with nested each loops?
$(document).ready(function()
{
$('#show-results').click(function()
{
$.post('JSAAN.php', function(data)
{
var pushedData = jQuery.parseJSON(data);
$.each(pushedData, function(i, serverData)
{
alert(i);
})
})
})
});
The idea here is to get into the question information in the middle level and print out the qusetion description, then based on the question type - loop through the options (if any) to create checkbox/radiobutton-groups before going on to the next question. The first number represents which stage of the multi stage poll I am currently working on. My plan is to divide it into 6 stages by hiding/showing various divs until the last page where the form is submitted through Ajax.
