How to convert a string to JSON ?

- by BrunoLM

How can I convert a string to JSON in javascript, is there a method that does that? Something like: var x = "{ id: 5, name: 'hello' }"; var y = /*something*/(x); alert(y.id + " " + y.name);

How to tell if JSON object is empty in jQuery

I have the following JSON: { "meta": { "limit": 20, "next": null, "offset": 0, "previous": null, "total_count": 0 }, "objects": [] } I'm interested in objects: I want to know if objects is empty and show an alert: something like this: success: function (data) { $.each(data.objects, function () { if data.objects == None alert(0) else :alert(1) });

Using jQuery to Insert a New Database Record

- by Stephen Walther

The goal of this blog entry is to explore the easiest way of inserting a new record into a database using jQuery and .NET. I’m going to explore two approaches: using Generic Handlers and using a WCF service (In a future blog entry I’ll take a look at OData and WCF Data Services). Create the ASP.NET Project I’ll start by creating a new empty ASP.NET application with Visual Studio 2010. Select the menu option File, New Project and select the ASP.NET Empty Web Application project template. Setup the Database and Data Model I’ll use my standard MoviesDB.mdf movies database. This database contains one table named Movies that looks like this: I’ll use the ADO.NET Entity Framework to represent my database data: Select the menu option Project, Add New Item and select the ADO.NET Entity Data Model project item. Name the data model MoviesDB.edmx and click the Add button. In the Choose Model Contents step, select Generate from database and click the Next button. In the Choose Your Data Connection step, leave all of the defaults and click the Next button. In the Choose Your Data Objects step, select the Movies table and click the Finish button. Unfortunately, Visual Studio 2010 cannot spell movie correctly :) You need to click on Movy and change the name of the class to Movie. In the Properties window, change the Entity Set Name to Movies. Using a Generic Handler In this section, we’ll use jQuery with an ASP.NET generic handler to insert a new record into the database. A generic handler is similar to an ASP.NET page, but it does not have any of the overhead. It consists of one method named ProcessRequest(). Select the menu option Project, Add New Item and select the Generic Handler project item. Name your new generic handler InsertMovie.ashx and click the Add button. Modify your handler so it looks like Listing 1: Listing 1 – InsertMovie.ashx using System.Web; namespace WebApplication1 { /// <summary> /// Inserts a new movie into the database /// </summary> public class InsertMovie : IHttpHandler { private MoviesDBEntities _dataContext = new MoviesDBEntities(); public void ProcessRequest(HttpContext context) { context.Response.ContentType = "text/plain"; // Extract form fields var title = context.Request["title"]; var director = context.Request["director"]; // Create movie to insert var movieToInsert = new Movie { Title = title, Director = director }; // Save new movie to DB _dataContext.AddToMovies(movieToInsert); _dataContext.SaveChanges(); // Return success context.Response.Write("success"); } public bool IsReusable { get { return true; } } } } In Listing 1, the ProcessRequest() method is used to retrieve a title and director from form parameters. Next, a new Movie is created with the form values. Finally, the new movie is saved to the database and the string “success” is returned. Using jQuery with the Generic Handler We can call the InsertMovie.ashx generic handler from jQuery by using the standard jQuery post() method. The following HTML page illustrates how you can retrieve form field values and post the values to the generic handler: Listing 2 – Default.htm <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Add Movie</title> <script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.js" type="text/javascript"></script> </head> <body> <form> <label>Title:</label> <input name="title" /> <br /> <label>Director:</label> <input name="director" /> </form> <button id="btnAdd">Add Movie</button> <script type="text/javascript"> $("#btnAdd").click(function () { $.post("InsertMovie.ashx", $("form").serialize(), insertCallback); }); function insertCallback(result) { if (result == "success") { alert("Movie added!"); } else { alert("Could not add movie!"); } } </script> </body> </html> When you open the page in Listing 2 in a web browser, you get a simple HTML form: Notice that the page in Listing 2 includes the jQuery library. The jQuery library is included with the following SCRIPT tag: <script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.js" type="text/javascript"></script> The jQuery library is included on the Microsoft Ajax CDN so you can always easily include the jQuery library in your applications. You can learn more about the CDN at this website: http://www.asp.net/ajaxLibrary/cdn.ashx When you click the Add Movie button, the jQuery post() method is called to post the form data to the InsertMovie.ashx generic handler. Notice that the form values are serialized into a URL encoded string by calling the jQuery serialize() method. The serialize() method uses the name attribute of form fields and not the id attribute. Notes on this Approach This is a very low-level approach to interacting with .NET through jQuery – but it is simple and it works! And, you don’t need to use any JavaScript libraries in addition to the jQuery library to use this approach. The signature for the jQuery post() callback method looks like this: callback(data, textStatus, XmlHttpRequest) The second parameter, textStatus, returns the HTTP status code from the server. I tried returning different status codes from the generic handler with an eye towards implementing server validation by returning a status code such as 400 Bad Request when validation fails (see http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html ). I finally figured out that the callback is not invoked when the textStatus has any value other than “success”. Using a WCF Service As an alternative to posting to a generic handler, you can create a WCF service. You create a new WCF service by selecting the menu option Project, Add New Item and selecting the Ajax-enabled WCF Service project item. Name your WCF service InsertMovie.svc and click the Add button. Modify the WCF service so that it looks like Listing 3: Listing 3 – InsertMovie.svc using System.ServiceModel; using System.ServiceModel.Activation; namespace WebApplication1 { [ServiceBehavior(IncludeExceptionDetailInFaults=true)] [ServiceContract(Namespace = "")] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class MovieService { private MoviesDBEntities _dataContext = new MoviesDBEntities(); [OperationContract] public bool Insert(string title, string director) { // Create movie to insert var movieToInsert = new Movie { Title = title, Director = director }; // Save new movie to DB _dataContext.AddToMovies(movieToInsert); _dataContext.SaveChanges(); // Return movie (with primary key) return true; } } } The WCF service in Listing 3 uses the Entity Framework to insert a record into the Movies database table. The service always returns the value true. Notice that the service in Listing 3 includes the following attribute: [ServiceBehavior(IncludeExceptionDetailInFaults=true)] You need to include this attribute if you want to get detailed error information back to the client. When you are building an application, you should always include this attribute. When you are ready to release your application, you should remove this attribute for security reasons. Using jQuery with the WCF Service Calling a WCF service from jQuery requires a little more work than calling a generic handler from jQuery. Here are some good blog posts on some of the issues with using jQuery with WCF: http://encosia.com/2008/06/05/3-mistakes-to-avoid-when-using-jquery-with-aspnet-ajax/ http://encosia.com/2008/03/27/using-jquery-to-consume-aspnet-json-web-services/ http://weblogs.asp.net/scottgu/archive/2007/04/04/json-hijacking-and-how-asp-net-ajax-1-0-mitigates-these-attacks.aspx http://www.west-wind.com/Weblog/posts/896411.aspx http://www.west-wind.com/weblog/posts/324917.aspx http://professionalaspnet.com/archive/tags/WCF/default.aspx The primary requirement when calling WCF from jQuery is that the request use JSON: The request must include a content-type:application/json header. Any parameters included with the request must be JSON encoded. Unfortunately, jQuery does not include a method for serializing JSON (Although, oddly, jQuery does include a parseJSON() method for deserializing JSON). Therefore, we need to use an additional library to handle the JSON serialization. The page in Listing 4 illustrates how you can call a WCF service from jQuery. Listing 4 – Default2.aspx <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Add Movie</title> <script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.js" type="text/javascript"></script> <script src="Scripts/json2.js" type="text/javascript"></script> </head> <body> <form> <label>Title:</label> <input id="title" /> <br /> <label>Director:</label> <input id="director" /> </form> <button id="btnAdd">Add Movie</button> <script type="text/javascript"> $("#btnAdd").click(function () { // Convert the form into an object var data = { title: $("#title").val(), director: $("#director").val() }; // JSONify the data data = JSON.stringify(data); // Post it $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "MovieService.svc/Insert", data: data, dataType: "json", success: insertCallback }); }); function insertCallback(result) { // unwrap result result = result["d"]; if (result === true) { alert("Movie added!"); } else { alert("Could not add movie!"); } } </script> </body> </html> There are several things to notice about Listing 4. First, notice that the page includes both the jQuery library and Douglas Crockford’s JSON2 library: <script src="Scripts/json2.js" type="text/javascript"></script> You need to include the JSON2 library to serialize the form values into JSON. You can download the JSON2 library from the following location: http://www.json.org/js.html When you click the button to submit the form, the form data is converted into a JavaScript object: // Convert the form into an object var data = { title: $("#title").val(), director: $("#director").val() }; Next, the data is serialized into JSON using the JSON2 library: // JSONify the data var data = JSON.stringify(data); Finally, the form data is posted to the WCF service by calling the jQuery ajax() method: // Post it $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "MovieService.svc/Insert", data: data, dataType: "json", success: insertCallback }); You can’t use the standard jQuery post() method because you must set the content-type of the request to be application/json. Otherwise, the WCF service will reject the request for security reasons. For details, see the Scott Guthrie blog post: http://weblogs.asp.net/scottgu/archive/2007/04/04/json-hijacking-and-how-asp-net-ajax-1-0-mitigates-these-attacks.aspx The insertCallback() method is called when the WCF service returns a response. This method looks like this: function insertCallback(result) { // unwrap result result = result["d"]; if (result === true) { alert("Movie added!"); } else { alert("Could not add movie!"); } } When we called the jQuery ajax() method, we set the dataType to JSON. That causes the jQuery ajax() method to deserialize the response from the WCF service from JSON into a JavaScript object automatically. The following value is passed to the insertCallback method: {"d":true} For security reasons, a WCF service always returns a response with a “d” wrapper. The following line of code removes the “d” wrapper: // unwrap result result = result["d"]; To learn more about the “d” wrapper, I recommend that you read the following blog posts: http://encosia.com/2009/02/10/a-breaking-change-between-versions-of-aspnet-ajax/ http://encosia.com/2009/06/29/never-worry-about-asp-net-ajaxs-d-again/ Summary In this blog entry, I explored two methods of inserting a database record using jQuery and .NET. First, we created a generic handler and called the handler from jQuery. This is a very low-level approach. However, it is a simple approach that works. Next, we looked at how you can call a WCF service using jQuery. This approach required a little more work because you need to serialize objects into JSON. We used the JSON2 library to perform the serialization. In the next blog post, I want to explore how you can use jQuery with OData and WCF Data Services.

Openlayers - LayerRedraw() / Feature rotation / Linestring coords

- by Ozaki

TLDR: I have an Openlayers map with a layer called 'track' I want to remove track and add track back in. Or figure out how to plot a triangle based off one set of coords & a heading(see below). I have an image 'imageFeature' on a layer that rotates on load to the direction being set. I want it to update this rotation that is set in 'styleMap' on a layer called 'tracking'. I set the var 'stylemap' to apply the external image & rotation. The 'imageFeature' is added to the layer at the coords specified. 'imageFeature' is removed. 'imageFeature' is added again in its new location. Rotation is not applied.. As the 'styleMap' applies to the layer I think that I have to remove the layer and add it again rather than just the 'imageFeature' Layer: var tracking = new OpenLayers.Layer.GML("Tracking", "coordinates.json", { format: OpenLayers.Format.GeoJSON, styleMap: styleMap }); styleMap: var styleMap = new OpenLayers.StyleMap({ fillOpacity: 1, pointRadius: 10, rotation: heading, }); Now wrapped in a timed function the imageFeature: map.layers[3].addFeatures(new OpenLayers.Feature.Vector( new OpenLayers.Geometry.Point(longitude, latitude), {rotation: heading, type: parseInt(Math.random() * 3)} )); Type refers to a lookup of 1 of 3 images.: styleMap.addUniqueValueRules("default", "type", lookup); var lookup = { 0: {externalGraphic: "Image1.png", rotation: heading}, 1: {externalGraphic: "Image2.png", rotation: heading}, 2: {externalGraphic: "Image3.png", rotation: heading} } I have tried the 'redraw()' function: but it returns "tracking is undefined" or "map.layers[2]" is undefined. tracking.redraw(true); map.layers[2].redraw(true); Heading is a variable: from a JSON feed. var heading = 13.542; But so far can't get anything to work it will only rotate the image onload. The image will move in coordinates as it should though. So what am I doing wrong with the redraw function or how can I get this image to rotate live? Thanks in advance -Ozaki Add: I managed to get map.layers[2].redraw(true); to sucessfully redraw layer 2. But it still does not update the rotation. I am thinking because the stylemap is updating. But it runs through the style map every n sec, but no updates to rotation and the variable for heading is updating correctly if i put a watch on it in firebug. If I were to draw a triangle with an array of points & linestring. How would I go about facing the triangle towards the heading. I have the Lon/lat of one point and the heading. var points = new Array( new OpenLayers.Geometry.Point(lon1, lat1), new OpenLayers.Geometry.Point(lon2, lat2), new OpenLayers.Geometry.Point(lon3, lat3) ); var line = new OpenLayers.Geometry.LineString(points); Looking for any way to solve this problem Image or Line anyone know how to do either added a 100rep bounty I am really stuck with this.

Why can't “knife data bag from file” find existing json file on chef server?

- by ellisera

Summary: I'm running into a problem with "knife data bag from file", where knife doesn't recognize the .json data bag file pulled down from a remote git repo. Background: I'm currently trying to transition from chef-solo use to chef server while using the cookbooks, data bags and other chef info from our remote git repo. I've currently pulled down a copy of our git repo and set the cookbook path and data bag path in knife.rb. I also loaded the cookbooks, made adjustments, etc. Details: When trying to load our .json data bags by doing "knife data bag add from file FOLDER FILE" it looks like it worked until I do "knife data bag list" and it comes up blank. So I decided to try adding the edit option at the end to see what's being loaded, if it is. This is the error I get: knife data bag from file local_settings test.json -e nano ERROR: Could not find or open file 'test.json' in current directory or in 'data_bags/local_settings/test.json' The data bag file does exist, in the proper location, in a tested, working json file. I've also sometimes gotten an error saying "could not open data bag "local_settings". I would obviously like to keep the data bag path within the appropriate git repo folder to be able to keep track of changes in a more centralized location (our git repo, as opposed to the chef server). Any solutions, advice or pointers in the right direction are appreciated.

LitJSON's JsonMapper.ToJson error: Max allowed object depth reached while trying to export from type

- by dev.e.loper

I have an object that I would like to convert to json inside one of the object's methods. I'm using LitJson library. Like so: protected override void Render(HtmlTextWriter writer) { ... writer.AddAttribute(HtmlTextWriterAttribute.Value, JsonMapper.ToJson(this)); .... } However JsonMapper.ToJson(this) produces a server error "Max allowed object depth reached while trying to export from type System.Drawing.Color". My guess is that because its trying to convert an object inside itself its going into some kind of infinite loop. Just curious what is actually happening.

fullCalendar className to multiple eventSources

I am trying to setup my fullCalendar event sources. instead of pulling all of my events through 1 source, I would like to use multiple sources (ie: google, and local json) Here is what I have so far (In short): eventSources: [ //CA HOLIDAYS $.fullCalendar.gcalFeed('http://www.google.com/calendar/feeds/en.canadian%23holiday%40group.v.calendar.google.com/public/basic', { className: 'holiday' }), //General events 'events.php?a=getAllCalendarEvents' ], The problem that I am having is, I can get the gCalFeed to have a className, but not exactly sure how to get my other source to have a className... Any ideas would be greatly appreciated.

But i'm a bit stuck here, because I'd like to load the tree either via UL/LI or better, with Jason/Ajax. my problem now is, that I dont understand how to provide ther url/links with LI or Jason, so that clicking an entry still opens the linked site in the iframe. Also don't know how I have to format parents/children/subchildren in Json.. Would anybody be so kind to give a sample with iframe and jason/ajax or iframe with ul/li? Thanks a lot :-) G

jQuery getJson returning null

- by Adam

I'm trying to use this api that lets you reference an exact text, but the getJson does not seem to be working, it's just returning null. $.getJSON('http://api.biblia.com/v1/bible/content/KJV.json?key=MYAPIKEY=John+3:16-18&style=bibleTextOnly', function(data) { alert(data); }); I just took the key out, i've been testing it with my real api key, and it works fine when i just visit the url. is there anything else i need to do to make it work? This is what you get from the url when you have an api key in the url: {"text":"For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. For God sent not his Son into the world to condemn the world; but that the world through him might be saved. He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God."}

Convert non-breaking spaces to spaces in Ruby

- by CoolAJ86

I have cases where user-entered data from an html textarea or input is sometimes sent with \u00a0 (non-breaking spaces) instead of spaces when encoded as utf-8 json. I believe that to be a bug in Firefox, as I know that the user isn't intentionally putting in non-breaking spaces instead of spaces. There are also two bugs in Ruby, one of which can be used to combat the other. For whatever reason \s doesn't match \u00a0 However [^[:print:]] (which definitely should not match) and \xC2\xA0 both will match, but I consider those to be less-than-ideal ways to deal with the issue. Are there other recommendations for getting around this issue?

What is the leading LINQ for JavaScript library?

- by Tom Tresansky

I'm looking for a JavaScript library that will allow me to query complex JSON objects using a LINQ-like syntax. A quick search found a couple of promising options that look they might offer what I need: LINQ to JavaScript and jLinq Does any one have any experience using them? What are some pros and cons? Is the performance comparable? Does the function-passing syntax of LINQ to JavaScript offer any hidden benefits (I personally find the syntax of jLinq more appealing on first glance)? What have you found lacking in either project? Did you ever try contacting the authors? How responsive were they? What project is more widely used?

How do I copy a JavaScript object into another object?

- by Josh K

Say I want to start with a blank JavaScript object: me = {}; And then I have an array: me_arr = new Array(); me_arr['name'] = "Josh K"; me_arr['firstname'] = "Josh"; Now I want to throw that array into the object so I can use me.name to return Josh K. I tried: for(var i in me_arr) { me.i = me_arr[i]; } But this didn't have the desired result. Is this possible? My main goal is to wrap this array in a JavaScript object so I can pass it to a PHP script (via AJAX or whatever) as JSON.

DataContractJsonSerializer produces list of hashes instead of hash

- by Jacques

I would expect a Dictionary object of the form: Dictionary<string,string> dict = new Dictionary<string,string>() {["blah", "bob"], ["blahagain", "bob"]}; to serialize into JSON in the form of: { "blah": "bob", "blahagain": "bob" } NOT [ { "key": "blah", "value": "bob" }, { "key": "blahagain", "value": "bob"}] What is the reason for what appears to be a monstrosity of a generic attempt at serializing collections? The DataContractJsonSerializer uses the ISerializable interface to produce this thing. It seems to me as though somebody has taken the XML output from ISerializable and mangled this thing out of it. Is there a way to override the default serialization used by .Net here? Could I just derive from Dictionary and override the Serialization methods? Posting to hear of any caveats or suggestions people might have.

Im trying to develop my first ASP.NET MVC web app and have run into a problem with the jquery ui autocomplete widget. At the moment I have a form with a number of text boxs which would lend themselves well to an autocomplete ability. The code for my "Make"(Car make) text box is show below: jquery: $(function() { $("#Make").autocomplete({ source: '<%=Url.Action("Make","AutoComplete") %>' }); }); ASP.NET MVC controller: public ActionResult Make(string term) { return Json(Service.GetHints(HintType.Make, term, 20)); } GetHints() returns an IList of Hints, an object with just label and value string properties. The documentation implies that this is what I should be returning to the jquery but it doesnt want to work? Can anyone give me any advice/help?

I have something like this: function cat_filter() { $.ajax({ type: "POST", url: 'json/cat_filter.aspx', data: "catId=" + "&styleId=" + "&colourId=" + "&sizeId=" + "&minPrice=" + "&maxPrice=", dataType: "json", beforeSend: function () { //load loading cursor }, success: function (data) { var CatItems = ""; for (var x = 0; x < data.PRODUCTS.length; x++) { CatItems += '<li class="jcarousel-item jcarousel-item-horizontal jcarousel-item-' + [x] + ' jcarousel-item-' + [x] + '-horizontal jcarousel-item-placeholder jcarousel-item-placeholder-horizontal"><a class="large_image" href="#"><img src="' + data.PRODUCTS[x].product_img + '" alt="' + data.PRODUCTS[x].product_name + '"></a><h3 class="geo_17_darkbrown">' + data.PRODUCTS[x].product_name + '</h3>'; if (data.PRODUCTS[x].product_onsale == 1) { CatItems += '<img alt="sale" src="assets/images/sale.gif" class="sale"><span class="geo_17_red_linethr">£' + data.PRODUCTS[x].product_retailprice + '</span>  <span class="price geo_17_darkbrown">£' + data.PRODUCTS[x].product_webprice + '</span>'; } else { CatItems += '<span class="price geo_17_darkbrown">£' + data.PRODUCTS[x].product_webprice + '</span>'; } if (data.PRODUCTS[x].product_COLOURS) { CatItems += '<span class="colour">'; for (var y = 0; y < data.PRODUCTS[x].product_COLOURS.length; y++) { CatItems += '<span><a href="' + data.PRODUCTS[x].product_COLOURS[y].colours_large + '"><img src="' + data.PRODUCTS[x].product_COLOURS[y].colours_thumb + '" alt="' + data.PRODUCTS[x].product_COLOURS[y].colour_name + '" /></a></span>'; } CatItems += '</span>'; } CatItems += '</li>'; } $('.carousel_00 ul').html(CatItems); }, complete: function () { //remove loading cursor } }); } This code generates this html: <div class="carousel_00"> <ul> <li><a href="#" class="large_image"><img src="assets/images/dress1.gif" alt="image"></a> <h3 class="geo_17_darkbrown">Rachel Dress</h3> <span class="price geo_17_darkbrown">£89.99</span> <span class="colour"> <span><a href="assets/images/big_image_1.gif"><img src="assets/images/black.gif" alt="balck"></a></span> <span><img src="assets/images/brown.gif" alt="brown"></span> <span><img src="assets/images/purple.gif" alt="purple"></span> </span> </li> <li><a href="#"><img src="assets/images/dress2.gif" alt="image"></a> <h3 class="geo_17_darkbrown">Rachel Dress</h3> <span class="price geo_17_darkbrown">£89.99</span> </li> <li><img class="sale" src="assets/images/sale.gif" alt="sale" /><a href="#"><img src="assets/images/dress3.gif" alt="image"></a> <h3 class="geo_17_darkbrown">Rachel Dress</h3> <span class="geo_17_red_linethr">£99.99</span>  <span class="price geo_17_darkbrown">£89.99</span> </li> <li><a href="#"><img src="assets/images/dress1.gif" alt="image"></a> <h3 class="geo_17_darkbrown">Rachel Dress</h3> <span class="price geo_17_darkbrown">£59.99</span> </li> <li><a href="#"><img src="assets/images/dress2.gif" alt="image"></a> <h3 class="geo_17_darkbrown">Rachel Dress</h3> <span class="price geo_17_darkbrown">£89.99</span> </li> <li><a href="#"><img src="assets/images/dress3.gif" alt="image"></a> <h3 class="geo_17_darkbrown">Rachel Dress</h3> <span class="price geo_17_darkbrown">£89.99</span> </li> <li><a href="#"><img src="assets/images/dress1.gif" alt="image"></a> <h3 class="geo_17_darkbrown">Rachel Dress</h3> <span class="price geo_17_darkbrown">£89.99</span> </li> <li><a href="#"><img src="assets/images/dress2.gif" alt="image"></a> <h3 class="geo_17_darkbrown">Rachel Dress</h3> <span class="price geo_17_darkbrown">£89.99</span> </li> <li><a href="#"><img src="assets/images/dress3.gif" alt="image"></a> <h3 class="geo_17_darkbrown">Rachel Dress</h3> <span class="price geo_17_darkbrown">£89.99</span> </li> </ul></div> What I need is that every 3 li's will be in div /div. I know that this is not semantic and not right, but this is only for example. (Basically if I will figure put how to do this, I will replace li's on spans and that div that i need outside li's on li). Will be very glad if someone will help me. Because code that I have is already too much for me.

getjson jquery parsing an array

- by Ozaki

TLDR: Want to get each heading from an array and insert it into a div without knowing what is inside the div using Jquery - getJSON. I have JSON array lets say: jsonfeed({ "items": [ { "d":{"title":"034324324-22344231-10"} }, { "d"{"title":"23423404-3423422-10"} }, { "d"{"title":"0234234324-32432422-10"} }, { "d"{"title":"0234234324-223534534-10"} ] }) And I want to parse it as for each "title" to insert it into a div. Trying along the lines of $.getJSON(url, function(data){ $.each(data.items, function(i,item){ $('#testfield').html('<p>' + item.d.title + '</p>'); }); }); to no avail. I am using Getjson in other places but in cases where I know what request I am making. e.g: $('#livetime').html(data.Time); Which is all working perfectly fine but in this case I need to get the details out of the array without knowing what is inside the array I'm sure there is something simple that I'm missing here or doing wrong ^^.
