  • JSON Object XHR and closures

    - by Sara Chipps
    Hi all, I have a JSON object that is populated by an XHR. I then need to update that object with values from a separate XHR call. The issue I am running into is the second call isn't being made at the correct time and I think it's an issue with how I structured my object. Here is what I have: function Proprietary() { var proprietary= this; this.Groups = {}; this.getGroups = function() { $.getJSON(group_url, function(data){proprietary.callReturned(data);}); } this.callReturned = function(data) { //Do stuff for(var i=0; i< data.groups.length; i++) { insparq.Groups[i] = data.groups[i]; $.getJSON(participant_url, function(p){proprietary.Groups[i].participants = p;}); } //the function call below is the action I want to occur after the object is populated. PopulateGroups(); } };

  • Javascript push Object to cookies using JSON

    - by Hunkeone
    Hi All on click button I need to add object to array and then write array to cookies. From the start this array can be not empty so I parse cookie first. function addToBasket(){ var basket = $.parseJSON($.cookie("basket")) if (basket.length==0||!basket){ var basket=[]; basket.push( { 'number' : this.getAttribute('number'), 'type' : this.getAttribute('product') } ); } else{ basket.push( { 'number' : this.getAttribute('number'), 'type' : this.getAttribute('product') } ); } $.cookie("basket", JSON.stringify(basket)); } And HTML <button type="button" class="btn btn-success btn-lg" number="12" product="accs" onclick="addToBasket()">Add</button> Unfortunately I'm getting Uncaught ReferenceError: addToBasket is not defined onclick.

  • Ampersand in JSON/PHP in POST

    - by svenkapudija
    I'm having a text field which is send via JSON and jQuery (wrapped with .toJSON function) to my server via AJAX and POST request. On PHP side I'm doing json_decode . Everything works but if I put ampersand (&) inside it splits up the POST parameter so its incomplete on PHP side (at least what var_dump($_POST) is writing out). Shouldn't the toJSON and json_decode do all the job (escaping)? I tried encodeURIComponent, & to &amp;, & to \u0026 and it's not working. What I'm doing wrong? AJAX call function execute() { this.setupUrl(); return $.ajax({ type: this.requestMethod, data: this.getDataParams(), url: this.url }); } function getDataParams() { if(this.data != undefined) { if(this.requestMethod == 'POST' || this.requestMethod == 'PUT') { return "data=" + $.toJSON(this.data); } else if (this.requestMethod == 'GET') { return this.data; } } else { return null; } }

  • Convert Json date string to JavaScript date object

    - by dagda1
    Hi, I have the following JSON object which has a date field in the following format: { "AlertDate": "\/Date(1277334000000+0100)\/", "Progress": 1, "ReviewPeriod": 12 } I want to write a regular expression or a function to convert it to a javascript object so that it is in the form: { "AlertDate": "AlertDate":new Date(1277334000000), "Progress": 1, "ReviewPeriod": 12 } The above date format fails validation in the JQuery parseJSON method. I would like to convert the 1277334000000+0100 into the correct number of milliseconds to create the correct date when eval is called after validation. Can anyone help me out with a good approach to solving this? Cheers Paul

  • Sorting issues in flexigrid with "json" data

    - by John Sieber
    I'm currently using flexigrid to display data in a current project, but am running into issues with its ability to properly sort certain columns that contain dates or numbers. The data is being sent from a ColdFusion CFC that selects the appropriate data and then delivers it in the proper "json" format. As the date/time stamps and other fields containing numbers are sent as "strings" they do not sort properly in the data grid. Is this a limitation of Flexigrid or am I sending the data improperly to Flexigrid? I can provide examples of my code if that is helpful.

  • jQuery Photo Search Results Pagination using AJAX and JSON

    - by Mark Richman
    I have a "photo search" page that needs to present search results in a 5x5 grid of photo thumbnails. I'd like to populate this grid using the JSON results of a jQuery $.ajax() call to my ASP.NET web service. Where I'm struggling is with pagination, where clicking [First][Prev][1][2][3]...[20][21][Next][Last] will call back again via ajax and repopulate the results with the appropriate images. So I need to find a solution to both the pagination control itself and the search results. Is there a jQuery plugin for this, or something I can easily adapt for my purposes?

  • Iterating through facebook comments JSON object failing

  • $.each - wait for jSON request before proceeding

    - by GaaayLooord
    I have an issue with the below code: the jQuery.each is speeding on without waiting for the JSON request to finish. As a result, the 'thisVariationID' and 'thisOrderID' variables are being reset by the latest iteration of a loop before they can be used in the slower getJSON function. Is there a way to make each iteration of the the .each wait until completion of the getJSON request and callback function before moving on to the next iteration? $.each($('.checkStatus'), function(){ thisVariationID = $(this).attr('data-id'); thisOrderID = $(this).attr('id'); $.getJSON(jsonURL+'?orderID='+thisOrderID+'&variationID='+thisVariationID+'&callback=?', function(data){ if (data.response = 'success'){ //show the tick. allow the booking to go through $('#loadingSML'+thisVariationID).hide(); $('#tick'+thisVariationID).show(); }else{ //show the cross. Do not allow the booking to be made $('#loadingSML'+thisVariationID).hide(); $('#cross'+thisVariationID).hide(); $('#unableToReserveError').slideDown(); //disable the form $('#OrderForm_OrderForm input').attr('disabled','disabled'); } }) })

  • Why doesn't `stdin.read()` read entire buffer?

    - by Shookie
    I've got the following code: def get_input(self): """ Reads command from stdin, returns its JSON form """ json_string = sys.stdin.read() print("json string is: "+json_string) json_data =json.loads(json_string) return json_data It reads a json string that was sent to it from another process. The json is read from stdin. For some reason I get the following output: json string is: <Some json here> json string is: Traceback (most recent call last): File "/Users/Matan/Documents/workspace/ProjectSH/addonmanager/addon_manager.py", line 63, in <module> manager.accept_commands() File "/Users/Matan/Documents/workspace/ProjectSH/addonmanager/addon_manager.py", line 49, in accept_commands json_data = self.get_input() File "/Users/Matan/Documents/workspace/ProjectSH/addonmanager/addon_manager.py", line 42, in get_input json_data =json.loads(json_string) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/__init__.py", line 338, in loads return _default_decoder.decode(s) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 365, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 383, in raw_decode raise ValueError("No JSON object could be decoded") So for some reason it reads an empty string from stdin instead of reading only the json. I've checked, and the code that writes to this process's stdin writes to it only once. What's wrong here?

  • jqGrid with JSON data renders table as empty

    - by jgreep
    I'm trying to create a jqgrid, but the table is empty. The table renders, but the data doesn't show. The data I'm getting back from the php call is: { "page":"1", "total":1, "records":"10", "rows":[ {"id":"2:1","cell":["1","image","Chief Scout","Highest Award test","0"]}, {"id":"2:2","cell":["2","image","Link Badge","When you are invested as a Scout, you may be eligible to receive a Link Badge.

If the php code will help, I can post it too.

  • Serializing Complex ViewModel with Json.Net Destabilization Error on Latest Version

    - by dreadlocks1221
    I just added the latest Version of JSON.Net and I get the System.Security.VerificationException: Operation could destabilize the runtime error when trying to use a controller (while running the application). I read in other posts that this issue should have been fixed in release 6 but I still have the problem. I even added *Newtonsoft.* to the ignore modules in the intellitrace options, which seems to have suppressed the error, but the post will just run forever and not return anything. Any help I can get would be greatly appreciated. [HttpPost] public string GetComments(int ShowID, int Page) { int PageSize = 10; UserRepository UserRepo = new UserRepository(); ShowCommentViewModel viewModel = new ShowCommentViewModel(); IQueryable<Comment> CommentQuery = showRepository.GetShowComments(ShowID); var paginatedComments = new PaginatedList<Comment>(CommentQuery, Page, PageSize); viewModel.Comments = new List<CommentViewModel>(); foreach (Comment comment in CommentQuery.Take(10).ToList()) { CommentViewModel CommentModel = new CommentViewModel { Comment = comment, PostedBy = UserRepo.GetUserProfile(comment.UserID) }; IQueryable<Comment> ReplyQuery = showRepository.GetShowCommentReplies(comment.CommentID); int ReplyPage = 0; var paginatedReplies = new PaginatedList<Comment>(ReplyQuery, ReplyPage, 3); CommentModel.Replies = new List<ReplyModel>(); foreach (Comment reply in ReplyQuery.Take(3).ToList()) { ReplyModel rModel = new ReplyModel { Reply = reply, PostedBy = UserRepo.GetUserProfile(reply.UserID) }; CommentModel.Replies.Add(rModel); } CommentModel.RepliesNextPage = paginatedReplies.HasNextPage; CommentModel.RepliesPeviousPage = paginatedReplies.HasPreviousPage; CommentModel.RepliesTotalPages = paginatedReplies.TotalPages; CommentModel.RepliesPageIndex = paginatedReplies.PageIndex; CommentModel.RepliesTotalCount = paginatedReplies.TotalCount; viewModel.Comments.Add(CommentModel); } viewModel.CommentsNextPage = paginatedComments.HasNextPage; viewModel.CommentsPeviousPage = paginatedComments.HasPreviousPage; viewModel.CommentsTotalPages = paginatedComments.TotalPages; viewModel.CommentsPageIndex = paginatedComments.PageIndex; viewModel.CommentsTotalCount = paginatedComments.TotalCount; return JsonConvert.SerializeObject(viewModel, Formatting.Indented); }

  • ASP.Net MVC Json Result: Parameters passed to controller method issue

    - by Moskie
    I'm having a problem getting a controller method that returns a JsonResult to accept parameters passed via the JQuery getJSON method. The code I’m working on works fine when the second parameter ("data") of the getJSON method call is null. But when I attempt to pass in a value there, it seems as if the controller method never even gets called. In this example case, I just want to use an integer. The getJSON call that works fine looks like this: $.getJSON(”/News/ListNewsJson/”, null, ListNews_OnReturn); The controller method is like this: public JsonResult ListNewsJson(int? id) { … return Json(toReturn); } By putting a breakpoint in the ListNewsJson method, I see that this method gets called when the data parameter of getJSON is null, but when I replace it with value, such as, say, 3: $.getJSON(”/News/ListNewsJson/”, 3, ListNews_OnReturn); … the controller method/breakpoint is never hit. Any idea what I'm doing wrong? I should also mention that the controller method works fine if I manually go to the address via my browser ("/News/ListNewsJson/3").

    Hi, I am trying to use Jquerys getJSON method to return data server side to my browser, what happens is the url the getJSON method points to does get reached but upon the postback the result does not get returned to the browser for some odd reason. I wasen't sure if it was because I was using MVC 2.0 and jQuery 1.4.1 and it differs to the MVC 1.0 version and jQuerys 1.3.2 version. . this is the code sections Controller public JsonResult StringReturn() { NameDTO myName = new NameDTO(); myName.nameID = 1; myName.name= "James"; myName.nameDescription = "Jmaes"; return Json(myName); } View with JQuery <script type="text/javascript"> $(document).ready(function () { $("#myButton").click(function () { $.getJSON("Home/StringReturn/", null, function (data) { alert(data.name); $("#show").append($("<div>" + data.name + "</div>")); }); }); }); </script> HTML <input type="button" value="clickMe" id="myButton"/> <div id="show">d</div>

  • Ruby array, javascript and json issue

    - by JohnMerlino
    Hey all, I am unable to get a highcharts plugin to render a chart in a rails application: http://github.com/loudpixel/highcharts-rails I believe it has something to do with the sql queries to the database placed in a ruby array, which the javascript is unable to intepret. This is what I have: def panels pass = Student.find_by_sql('SELECT COUNT(*) FROM students WHERE student_state = 1') fail = Student.find_by_sql('SELECT COUNT(*) FROM students WHERE student_state = 2') student_data = [ {:name => 'Pass', :y => pass}, {:name => 'Fail', :y => fail} ] pie_label_formatter = ' function() { if (this.y > 15) return this.point.name; }' pie_tooltip_formatter = ' function() { return "<strong>" + this.point.name + "</strong>: " + this.y + " %"; }' @pie_chart = Highchart.pie({ :chart => { :renderTo => "pie-chart-container", :margin => [50, 30, 0, 30] }, :plotOptions => { :pie => { :dataLabels => { :formatter => pie_label_formatter, :style => { :textShadow => '#000000 1px 1px 2px' } } } }, :series => [ { :type => 'pie', :data => student_data } ], :subtitle => { :text => 'April 2010' }, :title => { :text => 'Student Status Chart' }, :tooltip => { :formatter => pie_tooltip_formatter }, }) Note if I put this: :data = student_data.to_json It actually returns a json string of my query as text in the browser. Also, if I hard code values (e.g. :y = 1), it will render the chart properly. However, any database query will not render the chart properly. So I'm not sure exactly what the issue is. Any suggestions? Thanks.
