ajax parsing from JSON.stringify(Data) - ajax

I have the following ajax as you see below:
$.ajax({
url: url,
type: 'POST',
dataType: 'json',
data: JSON.stringify(json),
contentType: 'application/json; charset=utf-8',
success: function (Data) {
alert(JSON.stringify(Data));
},
error: error
});
When I do alert(JSON.stringify(Data));
it shows the data that see below. Data is the object I am sending back. It is returing 3 rows with 4 columns. How do I iterate through the data from the stringify as I need to store it into an HTML table?
{"Data":[{"Iden":"12","Date":"01/23/2011","City":"Clearwater","State":"FL"},{"Iden":"19","Date":"02/09/2012","City":"Elgin","State":"IL"},{"Iden":"14","Date":"06/22/2010","City":"Newport Beach","State":"CA"}]}

You want to use the jQuery each function:
$.each( Data, function(index, element){
alert( "Index: " + index + ", Element: " + element );
});

Before passing it to $.each function you have to parse JSON data
var d = JSON.parse(Data);
You can also directly call like this too
$.each( d.Data, function(index, element){
alert( "Index: " + index + ", Element: " + element );
});
For ex if the json is like this
{"note":{"to":"Tove","from":"Jani","heading":"Reminder","body":"Don't forget me this weekend!"}}
$.each( d.note, function(index, element){
alert( "Index: " + index + ", Element: " + element );
});

Syntax Error JSON file read with AJAX

I am getting a syntax error for the square bracket '[' from my JSON file. Given below is the JSON.
[
{
"Product Name":"CPE 10281",
"Application":"Tyres",
"Weight":150,
"Cost to Produce":5000,

"Application":"computers",
"Weight":250,
"Cost to Produce":4000,
"Grade":"H",
"Cost to Sell":25000,
"Strength":90
}
]
I am trying to use AJAX to read my JSON file.
$.ajax({
url: "dataProductJSON.json",
dataType: 'json',
mimeType: "application/json",
success: function (data) {
var item = [];
$.each(data, function (key, val) {
item.push('<li id="' + key + '">' + val + '</li>');
});
$('<ul/>', {
'class': 'interest-list',
html: item.join('')
}).appendTo('body');
},
});
I am running my html from Eclipse with Apache Geronimo as the server.
Please Help.
You are missing a { in the below line
success: function (data)
Make it
success: function (data) {
Edit
You are having parsing the data incorrectly , do it as below
$.ajax({
url: "test.html",
dataType: 'json',
mimeType: "application/json",
success: function (data) {
var item = [];
$.each(data, function (key, val){
$.each(val, function (innerKey, innerValue){
item.push('<li id="' + innerKey + '">' + innerValue + '</li>');
});
});
$('<ul/>', {
'class': 'interest-list',
html: item.join('')
}).appendTo('body');
},
});
You need to use 2 loop , one for the array and the other to loop through the object property
I tried things and it is working fine

success: function (data) {
for(var item in data){
console.info(item);//print key
console.info(data[item]);//print value
}
}
});
I hope this is what you need.

CFWheels Pagination using AJAX

I've searched the entire Internet, all of it, and cannot find an answer to this.
I'm using the ColdFusion CFWheels Framework to query a database. The query is done via AJAX like this:
var id = $("#ship-id").val();
$.ajax({
type: "POST",
url: "/my-controller/my-method?format=json",
data: {shipId: id},
dataType: "json",
success: function(response) {
var resultHtml = '';
$.each(response, function(i, value) {
resultHtml += '<tr><td>' + value.FIRSTNAME + ' ' + value.LASTNAME + '</td></tr>';
});
$("#my-table").html(resultHtml);
}
});
I need to paginate that result set. In CFWheels you normally do that by setting the handle, page, perPage and order values in the query like this:
var order = model("order").findAll(
select="id, firstname, lastname, email",
where="orderid IN (#ValueList(orders.id)#)",
handle="ordersQuery",
page=params.page,
perPage=5,
order="lastname"
);
Then you just put this line in your view:
<cfoutput>#paginationLinks(handle="ordersQuery")#</cfoutput>
But... how in the heck can you get pagination to work with an AJAX call?
I think that something along these lines might be your answer (notice I removed the url and added those params to data ...
$.ajax({
type: "POST",
data: {
shipId: id,
controller: myController,
action: myAction,
page: params.page,
},
dataType: "json",
success: function(response) {
var resultHtml = '';
$.each(response, function(i, value) {
resultHtml += '<tr><td>' + value.FIRSTNAME + ' ' + value.LASTNAME + '</td></tr>';
});
$("#my-table").html(resultHtml);
}
});

ajax jquery pass null value

I get null values in the controller when I process the request using jquery ajax
Controller
[HttpPost]
public ActionResult UpdateAnswers(string answers, string question, string controlid, int eventid)
{
var replacetext=string.Empty;
if (answers.Length>0)
replacetext = answers.Replace("\n", ",");
_service.UpdateAnswers(eventid, replacetext, controlid);
return PartialView("CustomizedQuestions");
}
Jquery - Ajax Code
var test = "{ answers: '" + $("#answerlist").val() + "', question: '" + title + "', controlid: '" + controlid + "', eventid: '" + eventid + "' }";
$.ajax({
url: '#Url.Action("UpdateAnswers")',
type: 'POST',
dataType: 'html',
contentType: 'application/html; charset=utf-8',
context: $(this),
// data: "{ answers: '"+$("#answerlist").val()+"' ,question: '"+ title +"', controlid:'"+ controlid +"',eventid:'"+ eventid+"'}",
data: JSON.stringify(test),
success: function (result) {
$(this).dialog("close");
},
error: function () {
//xhr, ajaxOptions, thrownError
alert('there was a problem saving the new answers, please try again');
}
});
Your contentType is wrong. Why did you set it to application/html when you pass JSON? Try like this:
var test = { answers: $('#answerlist').val(), question: title, controlid: controlid, eventid: eventid };
$.ajax({
url: '#Url.Action("UpdateAnswers")',
type: 'POST',
dataType: 'html',
contentType: 'application/json; charset=utf-8',
context: $(this),
data: JSON.stringify(test),
success: function (result) {
$(this).dialog("close");
},
error: function () {
//xhr, ajaxOptions, thrownError
alert('there was a problem saving the new answers, please try again');
}
});
or using application/x-www-form-urlencoded which is the default:
var test = { answers: $('#answerlist').val(), question: title, controlid: controlid, eventid: eventid };
$.ajax({
url: '#Url.Action("UpdateAnswers")',
type: 'POST',
dataType: 'html',
context: $(this),
data: test,
success: function (result) {
$(this).dialog('close');
},
error: function () {
//xhr, ajaxOptions, thrownError
alert('there was a problem saving the new answers, please try again');
}
});

Ajax Json multiple parameters

This code below sitting on a ASP.Net application on the Site.Mater....
I need to pass another two parameters from the default.aspx page, one asp:label and one asp:textbox
What is the easiest way to do that?
Thanks
<script type="text/javascript">
$(function () {
$(".tb").autocomplete({
source: function (request, response) {
$.ajax({
url: "TestWebService.asmx/FetchList",
data: "{ 'testName': '" + request.term + "'}",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
dataFilter: function (data) { return data; },
success: function (data) {
response($.map(data.d, function (item) {
return {
value: item.Name
}
}))
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert(textStatus);
}
});
},
minLength: 2
});
});
In your jQuery autocomplete, You need to change your data parameter to this:
data: "{ 'testName': '" + request.term + "' ,lbl: '" + $(".lblClass").text() + "' ,txt: '" + $(".txtClass").val() + "'}"
And then change your service method like this:
[WebMethod]
public List<string> FetchList(string testName, string lbl, string txt)
{
//...
}
Note:
.lblClass and .txtClass are classes for ASP:Lable and ASP:TextBox respectively.
