  • Convert json to a string using jquery

    - by becomingGuru
    I have a nested json. I want to post it as a form input value. But, seems like jquery puts "Object object" string into the value. It seems easier to pass around the string and convert into the native form I need, than dealing with json as I don't need to change anything once it is generated. What is the simplest way to convert a json var json = { "firstName": "John", "lastName": "Smith", "age": 25, "address": { "streetAddress": "21 2nd Street", "city": "New York", "state": "NY", "postalCode": "10021" }, "phoneNumber": [ { "type": "home", "number": "212 555-1234" }, { "type": "fax", "number": "646 555-4567" } ], "newSubscription": false, "companyName": null }; into its string form? var json = '{ "firstName": "John", "lastName": "Smith", "age": 25, "address": { "streetAddress": "21 2nd Street", "city": "New York", "state": "NY", "postalCode": "10021" }, "phoneNumber": [ { "type": "home", "number": "212 555-1234" }, { "type": "fax", "number": "646 555-4567" } ], "newSubscription": false, "companyName": null }' Following doesn't do what I need: Json.stringify()

  • YUI button onclick get value

    - by Simon
    I have a a set of yui buttons generated using the standard yui html. <span class="yui-button yui-checkbox-button" id="analystbutton1"> <span class="first-child"> <button type="button" class="facetbutton" tabindex="0" id="analystbutton1-button"> Joe Bloggs </button> </span> </span> I create the buttons like so, and I then have some javascript to create the button and the listener. var analystCButton1 = new YAHOO.widget.Button("analystbutton1", { type:"checkbox", value:"BLOGGS", checked:false }); analystCButton1.on("click", onFacetClick); Finally I have the onFacetClick function var onFacetClick = function (e) { // e is the event var target = YAHOO.util.Event.getTarget(e); var button = new YAHOO.widget.Button(target); alert(button.get('type')); alert(button.get('id')); alert(button.get('value')); }; When I click on any of my buttons the first two alerts display the type and id (although not what I would expect). I cannot get the value, the alert doesn't fire, but I see no error in FireBug or the error console. alert(button.get('type')); returns push - I would expect checkbox alert(button.get('id')); returns analystbutton1-button

  • Best solution for a comment table for multiple content types

    - by KRTac
    I'm currently designing a comments table for a site I'm building. Users will be able to upload images, link videos and add audio files to the profile. Each of these types of content must be commentable. Now I'm wondering what's the best approach to this. My current options are: 1. to have one big comments table and a link tables for every content type (comments_videos, ...) with comment_id and _id. 2. to have comments separated by the type of content their for. So each type of content would have his own comments table with the comments for that type.

  • Is generic Money<TAmount> a good implementation idea?

    - by jdk
    I have a Money Type that allows math operations and is sensitive to exchange rates so it will reduce one currency to another if rate is available to calculate in a given currency, rounds by various methods. It has other features that are sensitive to money, but I need to ask if the basic data type used should be made generic in nature. I've realized that the basic data type to hold an amount may differ for financial situations, for example: retail money might be expressed as all cents using int or long where fractions of cents do not matter, decimal is commonly used for its fixed behaviour, sometimes double seems to be used for big finance and large values sometimes a special BigInteger or 3rd-party type is used. I want to know if it would be considered good form to turn Money into Money<T_amount> so it can be used in any one of the above chosen scenarios?

  • NetDataContractSerialization throwing deserialization error

    - by htanias
    hi, I have methods which return interface and some methods which accepts interface as parameters. I am trying to use Net DataContractSerializer but I am getting following error... The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://tempuri.org/:id. The InnerException message was 'Error in line 1 position 120. XML 'Element' 'http://tempuri.org/:id' does not contain expected attribute 'http://schemas.microsoft.com/2003/10/Serialization/:Type'. The deserializer has no knowledge of which type to deserialize. Check that the type being serialized has the same contract as the type being deserialized.'. Please see InnerException for more details. Please help me how to resolve this error.... If I use Netdatacontract attribute on Operation Contract, can i use DataContract and Datamember attribute on serializable class??? Thanks in advance...

  • Why does my call to Activator.CreateInstance intermittently fail?

    - by Daniel Stutzbach
    I'm using the following code to access the Windows Explorer Shell's band site service: Guid GUID_TrayBandSiteService = new Guid(0xF60AD0A0, 0xE5E1, 0x45cb, 0xB5, 0x1A, 0xE1, 0x5B, 0x9F, 0x8B, 0x29, 0x34); Type shellTrayBandSiteService = Type.GetTypeFromCLSID(GUID_TrayBandSiteService, true); site = Activator.CreateInstance(shellTrayBandSiteService) as IBandSite; Mostly, it works great. A very small percentage of the time (less than 1%), the call to Activator.CreateInstance throws the following exception: System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {F60AD0A0-E5E1-45CB-B51A-E15B9F8B2934} failed due to the following error: 80040154. at System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean noCheck, Boolean& canBeCached, RuntimeMethodHandle& ctor, Boolean& bNeedSecurityCheck) at System.RuntimeType.CreateInstanceSlow(Boolean publicOnly, Boolean fillCache) at System.RuntimeType.CreateInstanceImpl(Boolean publicOnly, Boolean skipVisibilityChecks, Boolean fillCache) at System.Activator.CreateInstance(Type type, Boolean nonPublic) I've looked up the error code, and it appears to indicate that the service isn't registered. That's nonsense in my case, since I'm trying to access a service provided by the operating system (explorer.exe, to be specific). I'm stumped. What might cause Activator.CreateInstance fail, but only rarely?

  • Can the behaviour of new HTML5 form types be overridden?

    - by Mark Perkins
    I was wondering if anyone knew if it were possible to override the default behaviour of browsers that support the new HTML input types such as type="email" and type="date"? I appreciate that I could test if a browser supports an input type and provide a fallback for those browsers that don't, but what I want to know is is there any way to prevent that default behaviour from happening in browsers that do support it? For instance, if in Opera I want to use the date input type, but I don't want Opera to display the native datepicker (i.e. I want to replace it with my own custom one) is that possible? Are there any DOM events triggered like onDatePickerShow that one can hook into? I don't believe that this is possible, but if anyone knows for sure one way or the other I would love to hear from you.

  • Deserializing classes from XML generated using XSD.exe

  • Dynamically Forming a JSON object traversion without using eval.

    Given I have the following: (which is dynamically generated and varies in length) associations = ["employer", "address"]; Trying to traverse the JSON object, and wanting to form something like the following: data.employer.address or data[associations[0]][association[1]] Without doing this: eval("data."+associations.join('.')); Finally, I may be shunned for saying this, but is it okay to use eval in an instance like this? Just retrieving data.

  • HyperJAXB and IDREFs

    - by finrod
    I have eventually managed to fiddle HyperJAXB so that when XSD has complexType A and this has an IDREF to complexType B, then HyperJAXB will generate @OneToOne JPA annotations between the the two generated entities. However now I'm facing another problem: the XSD has complex type X that can IDREF to either complex type Y or complex type Z. In the end, I need instance of complex type X contain reference to either instance of class Y or class Z. Do you have any wild ideas how can this be done without manual alterations to the generated classes? And at the same time to make sure these entities are marshalled to a correct XML? How about using the JAXB plugin that allows generating classes so that they implement a particular interface? Could that lead anywhere?

  • Finding parents where child collection does not contain an item with a specific property value

    - by Colin Bowern
    I am trying to get a list of parents where the child collection does not contain an item of a specific type. The LINQ equivalent would be something like: dataset.Where(x => x.Items.FirstOrDefault(y => y.Type.Code == "ABC") == null) The object model is Parent Child (Items) Type Code If Parent is my aggregate root, how would I model this in NHibernate criteria/query? Here's my first attempt: var results = session.CreateCriteria<Parent>() .CreateCriteria("Items") .CreateCriteria("Type") .Add(Restrictions.Not(Restrictions.Eq("Code", "ABC"))) .SetResultTransformer(Transformers.DistinctRootEntity) .List<Parent>(); This doesn't seem to return the right entities - it just returns them all.

  • Weird generics compile error.

    - by Jouke van der Maas
    I have two classes, a base class and a child class. In the base class i define a generic virtual method: protected virtual Bar Foo<T() where T : Bar {} Then in my child class i try to do this: protected override BarChild Foo() // BarChild inherits Bar { return base.Bar<T as BarChild() } Visual studio gives this weird error: The type 'T' cannot be used as type parameter 'T' in the generic type or method 'Foo()'. There is no boxing conversion or type parameter conversion from 'T' to 'Bar'. Repeating the where clause on the child's override also gives an error: Constraints for override and explicit interface implementation methods are inherited from the base method, so they cannot be specified directly So what am i doing wrong here?

  • How to play an .mp3 using QBuffer with Phonon in a PyQt Qt environment

    - by thedax
    With the code I have right now I CAN play .mp3 data from files succesfully. However I need to play the same data using a QtCore.QBuffer (NOT from a file). When I use the example of the docs it errors an unexpected type of QBuffer! However...... that is what it SHOULD see, according to the docs. But............... it throws: TypeError: Phonon.MediaObject.setCurrentSource(Phonon.MediaSource): argument 1 has unexpected type 'QBuffer' The code I use is (1): someBuffer = QtCore.QBuffer() someBuffer.writeData(TrackData) mediaObject.setCurrentSource(someBuffer) I also tried (2): someBuffer = QtCore.QBuffer() mediaObject.setCurrentSource(someBuffer) someBuffer.writeData(TrackData) and (3): someBuffer = QtCore.QBuffer() someBuffer.writeData(TrackData) mediaObject.setCurrentSource(Phonon.MediaSource(someBuffer)) The last example (3) throws an different ERROR and wipes my Gui off screen ;-) ASSERT: "d-connected" in file /builddir/build/BUILD/phonon-4.5.1/phonon/streaminterface.cpp, line xxxx Notes: TrackData contains the mp3 data and IS PLAYING OK when I write it to a File and use that as a resource to mediaObject.setCurrentSource(Phonon.MediaSource())I also experimented with a QByteArray but that leads to the same "unexpected QBuffer" error. To be more precise everything I feed setCurrentSource is not accepted. Tried a string (errors an unexpected type of String), tried a QBuffer (errors an unexpected type of QBuffer), tried a QByteArray (errors an unexpected type of QByteArray). BTW: I run Qt, PyQt on Linux. Any ideas??

  • jquery performing calculation on dynamically generated elements

    - by user306472
    I have a table made up of a row of 3 input elements: Price, Quanity, and Total. Under that, I have two links I can click to dynamically generate another row in the table. All that is working well, but actually calculating a value for the total element is giving me trouble. I know how to calculate the value of the first total element but I'm having trouble extending this functionality when I add a new row to the table. Here's the html: <table id="table" border="0"> <thead> <th>Price</th><th>Quantity</th><th>Total</th> </thead> <tbody> <tr> <td><input id ="price" type = "text"></input></td> <td><input id ="quantity" type = "text"></input></td> <td><input id ="total" type = "text"></input></td> </tr> </tbody> </table> <a href="#" id="add">Add New</a> <a href="#" id="remove">Remove</a> Here's the jquery I'm using: $(function(){ $('a#add').click(function(){ $('#table > tbody').append('<tr><td><input id ="price" type = "text"></input></td><td><input id ="quantity" type = "text"></input></td><td><input id ="total" type = "text"></input></td></tr>'); }); $('a#remove').click(function(){ $('#table > tbody > tr:last').remove(); }); }); $(function(){ $('a#calc').click(function(){ var q = $('input#quantity').val(); var p = $('input#price').val(); var tot = (q*p); $('input#total').val(tot); }); }); I'm new to jquery so there's probably a simple method I don't know about that selects the relevant fields I want to calculate. Any guidance would be greatly appreciated.

Here's the code of form - <form action="" method="post" name="form1" id="form1"> <input type="hidden" value="15" name="ad_id"> <table width="100%" cellspacing="0" cellpadding="0" border="0" class="block"> <tbody><tr> <td valign="top">&nbsp;</td> <td align="right">all fields are required</td> </tr> <tr> <td valign="top">&nbsp;</td> <td align="center"></td> </tr> <tr> <td valign="top" width="150"><label for="name">Advertisement Name</label> *</td> <td><input type="text" size="45" value="Banner" id="name" name="name"> e.g Home Banner</td> </tr> <tr> <td valign="top"><label for="placement">Advertisement Placement</label></td> <td><select id="placement" name="placement"> Wide Skyscrapper 160 x 600 </tr> <tr> <td valign="top"><label for="code">Advertisement Code</label></td> <td><textarea rows="5" cols="45" id="code" name="code"></textarea></td> </tr> <tr> <td>Status</td> <td><label> <input type="radio" checked="checked" value="1" name="status"> Active</label> <label> <input type="radio" value="0" name="status"> Inactive</label></td> </tr> <input type="hidden" value="1" name="banner_uploaded" id="banner_uploaded"> <tr> <td>For Country - </td> <td> <select id="country" name="country"> <option>Not posting all the names of country</option> </select> </td> </tr> <tr> <td><label for="Scheduling">Valid From </label></td> <td><input type="text" value="" id="date-from" name="date-from"> Format : dd/mm/yyyy:hh/mm</td> </tr> <tr> <td><label for="Scheduling">Valid Till </label></td> <td><input type="text" value="" id="date-to" name="date-to"> Format : dd/mm/yyyy:hh/mm</td> </tr> <tr> <td>&nbsp;</td> <td align="right"><input type="submit" onclick="return validate_ad_form(add_adv)" value="Update Advertisement" class="button" name="update"></td> </tr> </tbody></table> </form> But I am getting $_POST['code'] empty when I am passing HTML code through it. When I pass plain text, it works fine. When I printed $_POST [i.e. used - print_r($_POST) ], I got the following output - Array ( [ad_id] = 15 [name] = Banner [placement] = ad_468x60 [code] = [status] = 1 [banner_uploaded] = 1 [country] = IN [date-from] = [date-to] = [update] = Update Advertisement ) Please be known, I haven't entered the 'date-from','date-to' fields. I have entered on purpose as StackOverflow don't allow me to post images! People,any help will be highly appreciated.
