  • Passing Object From Controller to JavaScript JQuery

    - by TMan
    This is driving me crazy. All I'm trying to do is to pass in a Id to a ActionMethod which is working and have an Object be returned to the javascript. Then in javascript, I want to be able to say something like..Objec.Property, ie/ Student.Name, or Student.GPA. Any help is appreciated. I tried json but couldn't get that to work either. ActionResult: [AcceptVerbs(HttpVerbs.Get)] public Epic GetEpicPropertyDetails(int id) { var Epictemplist = epicRepository.Select().Where(x => x.Id.Equals(id)); return Epictemplist.SingleOrDefault(); } javascript: <script type="text/javascript"> $(document).ready(function () { $(".ListBoxClass").click(function (event) { var selectedid = $(this).find("option:selected").val(); event.preventDefault(); $.get("/Estimate/GetEpicPropertyDetails", { id: selectedid }, function (result) { $(".TimeClass").val(result); }); }); }); </script> result.Name is obviously wrong I just dont know how to call this the right way.

  • Passing a model into RedirectToAction()

    - by larryq
    I'm curious how this works. In MVC you can call View() and pass a model as a parameter, but RedirectToAction (one of its incarnations at least) takes a 'routeValues' object, which appears to be the closest match. If your model is passed in this parameter will that model type be available in the subsequent action method? Or are there caveats involved that might prevent accurate translation in some circumstances?

  • Passing ViewData to PartialView returned from using Html.Action

    - by RWGodfrey
    I want to embed a partial view in an ASP.NET MVC page by returning it from an action method. In my base view, I would have: <%= Html.Action("MyPartialViewAction") %> My controller would have an action method like: [ChildActionOnly] public ActionResult MyPartialViewAction() { return PartialView("MyPartialView"); } I expected the returned partial view (MyPartialView) to have access to the ViewData that was set in the base page's controller action but that doesn't appear to be the case. If I insert the partial view by using the following in my base view it works: <% Html.RenderPartial("MyPartialView") %> I don't want to do that though because I want my "MyPartialViewAction" to execute logic to determine WHICH partial view to return.

  • Rails is not passing the "commit" button parameter

    - by Wayne M
    Reinstalling a Rails app on a new server. Part of the app can fork in one of two directions based on the button the user selects. This part isn't working, and when I look at the log I see the values that I gave the form, execept for the commit portion of the params hash. This seems to be why the app isn't working as expected (since there's nothing in params[:commit], but I have no idea why commit would not be passed in; the request is definitely a POST request, and all of the other parameters are there.

  • Passing a Smarty variable into Javascript link "src" attribute

    - by mikemick
    I've assigned a Smarty variable: {assign var="siteurl" value="http://website.com"} I can successfully use it in my header.html file to call a CSS link: <link rel="stylesheet" type="text/css" href="{$siteurl}/style.css" /> displays <link rel="stylesheet" type="text/css" href="http://website.com/style.css" /> However, when I do the same for a Javascript source, it literally prints out "{$siteurl}": <script type="text/javascript" src="{$siteurl}/scripts.js"></script> displays <script type="text/javascript" src="{$siteurl}/scripts.js"></script> Why isn't this Smarty variable displaying as expected?

  • Chrome extension - Message Passing

    - by Felipe Barreiros
    Hey there. I'm trying to get the info that is set on the Options Page to alter the behavior of my extension. Basically, if a checkbox on OptionsPage is set to true, the extension runs, otherwise it doesn't. I'm returning true on the background.html for testing purposes, but still, it doesn't work. Would you guys help me out? Thanks! Code being injected to the page: if(chrome.extension.sendRequest() == 'true') alert("checkbox set to true"); else alert("it is disabled"); background.html <script> chrome.extension.onRequest.addListener(function(){ return true; } </script>

  • JQuery\Javascript - Passing a function as a variable.

    - by Josh
    I was just curious if I could pass a function as a variable. For example: I have a function $('#validate').makeFloat({x:671,y:70,limitY:700}); I would like to do something like this: $('#validate').makeFloat({x:function(){ return $("#tabs").offset().left+$("#tabs").width();},y:70,limitY:700}); This does not work, but ideally every time the variable was accessed it would compute the new value. So if the window was resized it would automatically adjust as opposed to a variable passed in being static. I realize I can implement this directly inside the function\widget, but I was wondering if there was some way to do something like the above.

  • C++ compilation error when passing a function into remove_if

  • Passing System classes as constructor parameters

    - by mcl
    This is probably crazy. I want to take the idea of Dependency Injection to extremes. I have isolated all System.IO-related behavior into a single class so that I can mock that class in my other classes and thereby relieve my larger suite of unit tests of the burden of worrying about the actual file system. But the File IO class I end up with can only be tested with integration tests, which-- of course-- introduces complexity I don't really want to deal with when all I really want to do is make sure my FileIO class calls the correct System.IO stuff. I don't need to integration test System.IO. My FileIO class is doing more than simply wrapping System.IO functions, every now and then it does contain some logic (maybe this is the problem?). So what I'd like is to be able to test my File IO class to ensure that it makes the correct system calls by mocking the System.IO classes themselves. Ideally this would be as easy as having a constructor like so: public FileIO( System.IO.Directory directory, System.IO.File file, System.IO.FileStream fileStream ) { this.Directory = directory; this.File = file; this.FileStream = fileStream; } And then calling in methods like: public GetFilesInFolder(string folderPath) { return this.Directory.GetFiles(folderPath) } But this doesn't fly since the System.IO classes in question are static classes. As far as I can tell they can neither be instantiated in this way or subclassed for the purposes of mocking.

  • java: assigning object reference IDs for custom serialization

    - by Jason S
    For various reasons I have a custom serialization where I am dumping some fairly simple objects to a data file. There are maybe 5-10 classes, and the object graphs that result are acyclic and pretty simple (each serialized object has 1 or 2 references to another that are serialized). For example: class Foo { final private long id; public Foo(long id, /* other stuff */) { ... } } class Bar { final private long id; final private Foo foo; public Bar(long id, Foo foo, /* other stuff */) { ... } } class Baz { final private long id; final private List<Bar> barList; public Baz(long id, List<Bar> barList, /* other stuff */) { ... } } The id field is just for the serialization, so that when I am serializing to a file, I can write objects by keeping a record of which IDs have been serialized so far, then for each object checking whether its child objects have been serialized and writing the ones that haven't, finally writing the object itself by writing its data fields and the IDs corresponding to its child objects. What's puzzling me is how to assign id's. I thought about it, and it seems like there are three cases for assigning an ID: dynamically-created objects -- id is assigned from a counter that increments reading objects from disk -- id is assigned from the number stored in the disk file singleton objects -- object is created prior to any dynamically-created object, to represent a singleton object that is always present. How can I handle these properly? I feel like I'm reinventing the wheel and there must be a well-established technique for handling all the cases.

  • How do I reference the other object in django models

    - by UserZero
    Hi, first post here.In Django, I want to have many files be associated with a particular model, so I'm doing a seperate model called files and have model 'A' 'have many' files. But I want my files to be saved in director named by model 'A'. So For example I want something like this: class Show(models.Model): name = models.CharField() showfolder = models.FilePathField() class Episode(models.Model): show = models.ForeignKey(Show) name = models.CharField() files = models.ManyToManyField(mp3) class Mp3(models.Model): file = FileField(upload_to=Episode.show.showfolder) So hopefully that last line expresses what I WANT it to do(get the folder name from Show object associated with the episode). The question is how would I really write that?(besides jumping through hoops in the controller.) Thanks.

  • C Programming - Passing a pointer to array

    - by Pedro
    How do I pass a pointer value to an array of the struct; For example, on a txt I have this: John Doe;[email protected];214425532; My code: typedef struct Person{ char name[100]; char email[100]; int phone; }PERSON; int main(){ PERSON persons[100]; FILE *fp; char *ap_name; char *ap_email; char *ap_phone; char line[100]; fp=("text.txt","r"); if(fp==NULL){ exit(1); } else{ fgets(line,100,fp); ap_name=strtok(line,";"); ap_email=strtok(NULL,";"); ap_phone=strtok(NULL,";"); } return 0; } My question is how can I pass the value of ap_name, ap_email, ap_phone to the struct? And, do I need to use all of these pointers?

  • Object pointer value as key into dictionary

    - by Ranking Stackingblocks
    I want to use the object's reference value as a key into a dictionary, as opposed to a copy of value of the object. So, I essentially want to store an object associated with a particular instance of another object in a dictionary and retrieve that value later. Is this possible? Is it completely against the idea of NSDictionary? I can tell that I am probably approaching this the wrong way because the dictionary wants me to implement NSCopying on the object itself, which doesn't really make sense in terms of what I'm doing. I can see that what I should really be doing is wrapping the pointer value, but that seems a little mad. Advice would be appreciated.

  • Is it ok to reference .Net assemblies liberally?

    - by panamack
    I'm building a WPF application and working with the MVVM pattern. I have 4 projects in my solution, 3 class libraries, Data, Model and ViewModel and the WPF executable View. Is there anything wrong with the Model referencing WindowsBase so that I can use ObservableCollection<T> for example or can I just make use of what I intuitively feel I need without worrying about the original purposes of the class in the framework e.g. collection databinding.

  • Passing an arbritrary JavaScript object in Xul

    - by Tom Brito
    I'm following this example to pass an object to a window, but when it as an argument it's with "undefined" value. This is my first window (obs. dump is the way to print to console when debug options are turned on): <?xml version="1.0"?> <?xml-stylesheet href="chrome://global/skin/" type="text/css"?> <!DOCTYPE window SYSTEM "chrome://XulWindowArgTest/locale/XulWindowArgTest.dtd"> <window id="windowID" width="400" height="300" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"> <script> <![CDATA[ function onClickMe(event) { dump("begin\n"); try { var args = { param1: true, param2: 42 }; args.wrappedJSObject = args; var watcher = Components.classes["@mozilla.org/embedcomp/window-watcher;1"].getService(Components.interfaces.nsIWindowWatcher); watcher.openWindow(null, "chrome://XulWindowArgTest/content/about.xul", "windowName", "chrome", args); } catch (e) { dump("error: " + e + "\n"); } dump("end\n"); } ]]> </script> <button label="Click me !" oncommand="onClickMe();" /> </window> and my second window: <?xml version="1.0"?> <?xml-stylesheet href="chrome://global/skin/" type="text/css"?> <!DOCTYPE window SYSTEM "chrome://XulWindowArgTest/locale/XulWindowArgTest.dtd"> <window xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul" onload="onload()"> <script> <![CDATA[ function onload() { dump('arg = ' + window.arguments[0].wrappedJSObject + "\n"); } ]]> </script> <label value="test" /> </window> when the second window loads, it calls the onload and prints: arg = undefined Any idea how to fix it?

  • Passing through lists from jQuery to the service

    - by thedixon
    I'm sure I've done this in another solution, but I can't seem to find any solution as to do it again and wondered if anyone can help me... This is my WebAPI code: public class WebController : ApiController { public void Get(string telephone, string postcode, List<Client> clients) { } } And, calling this from jQuery: function Client(name, age) { this.Name = name; this.Age = age; } var Clients = []; Clients.push(new Client("Chris", 27)); $.ajax({ url: "/api/Web/", data: { telephone: "999", postcode: "xxx xxx", clients: Clients } }); But the "clients" object always comes back as null. I've also tried JSON.stringify(Clients), and this is the same result. Can anyone see anything obvious I'm missing here?

  • Passing around a SqlConnection

    - by Chris
    I have created a TransactionScope and within the scope various items are created and updated in the database. During this process I make a lot of calls to the database. Originally I opened a SqlConnection in the beginning of the TransactionScope and passed it around to any function that made a DB call then I closed the connection after all the calls are made and before the transaction commits. Is it better to do this or to open and close a connection for each call?

  • Django | passing form values

    - by MMRUser
    I want to create a user sign up process that requires two different forms with the same data one (1st form) is for filling out the data and other one (2nd form) is for displaying the filled data as a summery (before actually saving the data) so then user can view what he/she has filled up... my problem is that how do I pass 1st form's data in to the 2nd one .. I have used the basic Django form manipulation mechanism and passed the form field values to the next form using Django template tags.. if request.method == 'POST': form = Users(request.POST) if form.is_valid(): cd = form.cleaned_data try: name = cd['fullName'] email = cd['emailAdd'] password1 = cd['password'] password2 = cd['password2'] phoneNumber = cd['phoneNumber'] return render_to_response('signup2.html', {'name': name, 'email': email, 'password1': password1, 'password2': password2, 'phone': phone, 'pt': phoneType}) except Exception, ex: return HttpResponse("Error %s" % str(ex)) and from the second from I just displayed those field values using tags and also used hidden fields in order to submit the form with values, like this: <label for="">Email:</label> {{ email }} <input type="hidden" id="" name="email" class="width250" value="{{ email }}" readonly /> It works nicely from the out look, but the real problem is that if someone view the source of the html he can simply get the password even hackers can get through this easily. So how do I avoid this issue.. and I don't want to use Django session since this is just a simple sign up process and no other interactions involved. Thanks.
