geting one by one char in jquery by Json

I have asp.net mvc 2 application. since couple of da开发者_如何学JAVAys I was trying to read the List from action of controller to Jquery by returning the Json through the action. but need lot of time and effort to resolve this.now i am able to read the json data by using :

$.getJSON('/LoadTest/GetAllQuestionsForTest', function(data) {
    $.each(data, function(i,item) {
        alert(item);
    });
});

since, my json output is :

[{"QuestionId":2,"QuestionText":"Question 1","TopicId":1},{"QuestionId":3,"QuestionText":"Question 2","TopicId":1}]

where as I am getting here one by one char in alert box rather than string like "QuestionId". I want to read the value of "QuestionId" and "QuestionText" from this script how can i do that ? even i tried data["QuestionId"] but anable to read it

Edited

This is working for me :

      $.getJSON('/LoadTest/GetAllQuestionsForTest', function(data) {

                var t = $.parseJSON(data);
                alert(t[0].QuestionText);


            });

but showing only 0'th indexed value. I want to get count of objects in data collection. so that i can iterate it. how to do that?

You can try:

alert(data[0].QuestionId)

try to do:

$.get("/LoadTest/GetAllQuestionsForTest", function(data) {
   alert(data);
   var t = $.parseJSON(data);
   alert(t);
})

What the output ?

btw you using this on your controller? :

return Json(object, JsonRequestBehavior.AllowGet);

I think you need to use

alert(data[i].QuestionId);
alert(data[i].QuestionText);

Function each in this case is grabbing each array. You probably want to iterate the values of the arrays with an inner each.

$.each(json, function(i,item) {
    $.each(item, function(j,subitem) {
        alert(subitem);       
    });
});

You're almost there.

It looks like

$.each(data, function(i) {
    alert(data[i].QuestionId);
});

should do the trick?

i think

alert(item[i].QuestionId);

ok lets remove the each.

write

alert(data[0].QuestionId);

instead

$.each(data, function(i,item) {
        alert(item);
    });
