Yes, the data will show as [object Object] from an alert().

If you want to analyze the data as it has returned you should log it to the web console with console.log(data); instead.

You're then free to use the data in the callback. Provided you returned a json encoded object from PHP, you don't even have to massage the data. Just use data.prop1, data.prop2... etc

you cannot view the content of an object or array using alert. if you use google chrome or firefox with firebug plugins, use console.log(data); instead of alert(data);
press F12 just before you load the page to enable / show developer toolbar, you should be able to see the object in the console of the firebug or chrome.

good luck.

I believe F12 is for FF and IE only. See here for details. :) – Jordan Arseno Feb 15 '12 at 5:47
    
Yes, F12 only works in FF (if you have firebug plugins), IE and Chrome. I've mention FF and Chrome in my answer, but I forgot mentioning IE. Thanks, Jordan. – Andrew Leonheart Mar 7 '12 at 6:58

var jsonData = [{"data":"oneone"},{"name":"onetwo"}];
for(var a in jsonData) {
    if(jsonData.hasOwnProperty(a)) {
        for(var b in jsonData[a]) {
            if(jsonData[a].hasOwnProperty(b)) {                                
                alert(jsonData[a][b]);
            }
        }
    }

Loop the json array

function show(id){  

    // validation / client side.
    // function - lll to stringmatch - name proper.
    $.ajax({    
        type    : "POST",
        cache   : true,
        dataType: "json",
        url     : "a.php",
        data    : {
                    proid:id
                  },                
        success: function(data) {
          var str = '<div><ul>';
         for (i=0;i<data.length;i++){
                  str += '<li>'+data[i]['json_index']+'</li>';
            }
         str +='</ul></div>';
