  • jQuery and CodeIgniter AJAX with JSON not working

    - by thedp
    Hello, I trying to make my first AJAX with JSON call using jQuery and CodeIgniter. But for some weird reason it's not working. The jQuery code: var item = "COOL!"; $.post("http://192.168.8.138/index.php/main/test", { "item" : item }, function(data){ alert(data.result); }, "json"); The CodeIgniter code: <?php class main extends Controller { function test() { $item = trim($this->input->post('item')); $array = array('result' => $item); echo json_encode($array); } } ?> I tried to access the http://192.168.8.138/index.php/main/test page manually and it seems to be working, I got: {"result":""} I also tried to use Firebug to see XMLHttpRequest but saw nothing. I have no idea what am I doing wrong... Need help really badly. Thank you.

  • jqgrid - edit form field combobox not defaulting to selected row value after first edit

    - by ooo
    i am using jqgrid with asp.net-mvc. I have an edit form (using jqmodal) which works great but for some reason one combobox field doesn't default to the current selected row after the first time i bring up the edit form. the weird thing is that i have many other comboboxes which work fine every time and i don't see any real difference. here is an example of the field that doesn't work: { name: "TechOwner", index: "TechOwner", width: 70, editable: true, edittype: "select", editoptions: { dataUrl: "/Person/GetSelectData" }, editrules: { required: true} }, and here is a field that works fine: { name: "FundingType", index: "FundingType", align: "left", width: 25, editable: true, edittype: "select", editoptions: { dataUrl: "/Project/FundingGetSelectData" }, editrules: { required: true} }, the dropdown is getting populated with all options (including the current selected row option) but its just defaulting to the top item) instead of one that matches the current row. is there anything to look out for here that may cause this behavior?

  • Intersecting boundaries with lucene

    - by Silvio Donnini
    I'm using Lucene, and I'm trying to find a way to index and retrieve documents that have a ranged property. For example I have: Document 1: Price:[30 TO 50] Document 2: Price:[45 TO 60] Document 3: Price:[60 TO 70] And I would like to search for all the documents whose ranges intersect a specific interval, in the above example, if I search for Price in [55 TO 65] I should get Document 2 and Document 3 as results. I don't think NumericRangeQueries alone would do the trick, I need to work on the index with something similar to R-trees, but are they implemented in Lucene? Also, I suppose that what I need should be a subclass of MultiTermQuery, because the query Price in [55 TO 65] has two boundaries, but I don't see anything suitable among MultiTermQuery's subclasses. Any help is appreciated, thanks, Silvio P.S. I'm using Lucene 2.9.0, but I can update to the latest release if needed.

  • How do I sum up weighted arrays in PHP?

    - by christian studer
    Hod do I multiply the values of a multi-dimensional array with weigths and sum up the results into a new array in PHP or in general? The boring way looks like this: $weights = array(0.25, 0.4, 0.2, 0.15); $values = array ( array(5,10,15), array(20,25,30), array(35,40,45), array(50,55,60) ); $result = array(); for($i = 0; $i < count($values[0]); ++$i) { $result[$i] = 0; foreach($weights as $index => $thisWeight) $result[$i] += $thisWeight * $values[$index][$i]; } Is there a more elegant solution?

  • In SQL / MySQL, can a Left Outer Join be used to find out the duplicates when there is no Primary ID

    - by Jian Lin
    I would like to try using Outer Join to find out duplicates in a table: If a table has Primary Index ID, then the following outer join can find out the duplicate names: mysql> select * from gifts; +--------+------------+-----------------+---------------------+ | giftID | name | filename | effectiveTime | +--------+------------+-----------------+---------------------+ | 2 | teddy bear | bear.jpg | 2010-04-24 04:36:03 | | 3 | coffee | coffee123.jpg | 2010-04-24 05:10:43 | | 6 | beer | beer_glass.png | 2010-04-24 05:18:12 | | 10 | heart | heart_shape.jpg | 2010-04-24 05:11:29 | | 11 | ice tea | icetea.jpg | 2010-04-24 05:19:53 | | 12 | cash | cash.png | 2010-04-24 05:27:44 | | 13 | chocolate | choco.jpg | 2010-04-25 04:04:31 | | 14 | coffee | latte.jpg | 2010-04-27 05:49:52 | | 15 | coffee | espresso.jpg | 2010-04-27 06:03:03 | +--------+------------+-----------------+---------------------+ 9 rows in set (0.00 sec) mysql> select * from gifts g1 LEFT JOIN (select * from gifts group by name) g2 on g1.giftID = g2.giftID where g2.giftID IS NULL; +--------+--------+--------------+---------------------+--------+------+----------+---------------+ | giftID | name | filename | effectiveTime | giftID | name | filename | effectiveTime | +--------+--------+--------------+---------------------+--------+------+----------+---------------+ | 14 | coffee | latte.jpg | 2010-04-27 05:49:52 | NULL | NULL | NULL | NULL | | 15 | coffee | espresso.jpg | 2010-04-27 06:03:03 | NULL | NULL | NULL | NULL | +--------+--------+--------------+---------------------+--------+------+----------+---------------+ 2 rows in set (0.00 sec) But what if the table doesn't have a Primary Index ID, then can an outer join still be used to find out duplicates?

  • Difference between mutableArrayValueForKey and calling insertObject:inEmployeesAtIndex: directly

    - by jasonbogd
    I have a question regarding using KVO-compliant methods to insert/remove objects from an array. I'm working through Aaron Hillegass' Cocoa Programming for Mac OS X and I saw the following line of code (in the insertObject:inEmployeesAtIndex: method: [[undoManager prepareWithInvocationTarget:self] removeObjectFromEmployeesAtIndex:index]; Correct me if I'm wrong, but I always thought it was better to call mutableArrayValueForKey: and then removeObjectAtIndex:...so I tried changing the above line to this: [[undoManager prepareWithInvocationTarget:[self mutableArrayValueForKey:@"employees"]] removeObjectAtIndex:index]; And it didn't work. Can someone explain the difference and why the first line works but the second line doesn't?

  • Tokenizer for full-text

    - by user72185
    This should be an ideal case of not re-inventing the wheel, but so far my search has been in vain. Instead of writing one myself, I would like to use an existing C++ tokenizer. The tokens are to be used in an index for full text searching. Performance is very important, I will parse many gigabytes of text. Edit: Please note that the tokens are to be used in a search index. Creating such tokens is not an exact science (afaik) and requires some heuristics. This has been done a thousand time before, and probably in a thousand different ways, but I can't even find one of them :) Any good pointers? Thanks!

  • Populate DataTable with LINQ in C#

    - by RaYell
    I have a method in my app that populates DataTable with the data using the following code: DataTable dt = this.attachmentsDataSet.Tables["Attachments"]; foreach (Outlook.Attachment attachment in this.mailItem.Attachments) { DataRow dr = dt.NewRow(); dr["Index"] = attachment.Index; dr["DisplayName"] = String.Format( CultureInfo.InvariantCulture, "{0} ({1})", attachment.FileName, FormatSize(attachment.Size)); dr["Name"] = attachment.FileName; dr["Size"] = attachment.Size; dt.Rows.Add(dr); } I was wondering if I could achieve the same functionality using LINQ in order to shorten this code a bit. Any ideas?

  • Route alias, is it possible?

    - by benoror
    I have a Vehicle model: map.resources :vehicles, :has_many => :suppliers Everything works great, but Vehicle has a boolean attribute is_truck. I want to make an Alias so I can get the same resources but with the "truck" word, I tried with: map.trucks '/trucks', :controller => :vehicles, :action => :index, :is_truck => true map.trucks '/trucks/by_supplier/:supplier', :controller => :vehicles, :action => :index, :is_truck => true The first one works well, but when I search within a Form the second doesn't work and searches all suppliers. Is it possible to map.resources for an alias ?

  • Load first page on splashscreen using phonegap on android

    - by Syg
    Hi i'm using phonegap in conjunction with Jquery mobile. I'm trying to immediately fetch the main page, while showing the user a splashscreen. In PhoneGap for Android i'm using this super.setIntegerProperty("splashscreen", R.drawable.splash); super.loadUrl("file:///android_asset/www/index.html", 2000); While this loads the splash, it also delays the loading of index.html. It it possible to start fetching it right away? Also, if not with phonegap, has anybody done this using JQM instead of phonegap? UPDATE: After using it with a slower loading first page (doing a json request) it kinda looks like the splash screens shows for a longer period of time, so this appears to be the default behavior

  • How do I force SSL for some URLs and force non-SSL for all others?

    - by brad
    I'd like to ensure that certain URLs on my site are always accessed via HTTPS while all other URLs are accessed via HTTP. I can get either case working in my .htaccess file, however if I enable both, then I get infinite redirects.

  • A controller problem using a base CRUD model

    - by rkj
    In CodeIgniter I'm using a base CRUD My_model, but I have this small problem in my browse-controller.. My $data['posts'] gets all posts from the table called "posts". Though the author in that table is just a user_id, which is why I need to use my "getusername" function (gets the username from a ID - the ID) to grab the username from the users table. Though I don't know how to proceed from here, since it is not just one post. Therefore I need the username to either be a part of the $data['posts'] array or some other smart solution. Anyone who can help me out? function index() { $this->load->model('browse_model'); $data['posts'] = $this->browse_model->get_all(); $data['user'] = $this->browse_model->getusername(XX); $this->load->view('header'); $this->load->view('browse/index', $data); $this->load->view('footer'); }

  • a question about rails general practice with REST, json, and ajax

    - by Nik
    Hi all, I have this question concerning REST I think: I have read a few rest tutorials and the feeling I get from them is that each action in a restful controller tends to be lean and almost single purpose: "Index gives off a collection of a model show gives off one model edit/new a prep place for changing/create a model update/create changes and makes new model deletes removes one model" After reading all these tutorials, rest seems to be to be a means to create an interface for a model, much like active resource type of thing. the mantra seems to be "controller provides data and data only and is also pretty convention over configuration, so expect projects_path to return a bunch of projects" I can understand that, and I like the cleanliness. But here's when I run into some trouble in reality in applying these guidelines: say three models, Project with attrib title, User with attrib name, and Location with attrib address. Say in views/users/index.html.erb, I want to use Ajax to fetch and display a project in a div#project_display when the user clicks on a project element, I know that I can use views/projects/show.js.rjs like this: page.replace_html 'project_display' "#{@project.name}" where in the projects_controller.rb def show @project = Project.find(params[:id]) repsond_to do |format| format.js and other formats... end end I have no problem in doing that for a couple of years now. BUT doesn't that mean that my JS response for the project#show action is LOCkED to present data to div#project_display element and show only whatever I that rjs template says it should show? That's very limiting and doesn't sound very "interface" like. I have never used JSON before or much XML, so I thought, maybe the JS response should send back raw stuff, like JSON and somehow the page on which the ajax request was called has the instruction on what do to with these raw data. That sounds a lot more flexible, doesn't it? Because look back at that exmpale, what if in the views/locations/index.html.erb, I want to do the exact same thing except I want to put the response in div#project_goes_here and the response should be #{project.name} I know this is a trivial change but that's the point: the RJS only allows one template at a time. So I think the JSON route is the way to go, but how does the already loaded page, the one that the ajax call came from, know when or how to "look forward" to incoming data? I read that PrototypeJS has this template thing, I wouldn't mind using it with JSON, but if you can demonstrate this or other means for displaying received-from-ajax data, I am all attention. Thank You

  • Document Similarity: Comparing two documents efficiently

    - by seanieb
    I have a loop that calculates the similarity between two documents. It collects all the tokens in a document and their scores, and places them in dictionary. It then compares the dictionaries This is what I have so far, it works, but is super slow: # Doc A cursor1.execute("SELECT token, tfidf_norm FROM index WHERE doc_id = %s", (docid[i][0])) doca = cursor1.fetchall() #convert tuple to a dictionary doca_dic = dict((row[0], row[1]) for row in doca) #Doc B cursor2.execute("SELECT token, tfidf_norm FROM index WHERE doc_id = %s", (docid[j][0])) docb = cursor2.fetchall() #convert tuple to a dictionary docb_dic = dict((row[0], row[1]) for row in docb) # loop through each token in doca and see if one matches in docb for x in doca_dic: if docb_dic.has_key(x): #calculate the similarity by summing the products of the tf-idf_norm similarity += doca_dic[x] * docb_dic[x] print "similarity" print similarity I'm pretty new to Python, hence this mess. I need to speed it up, any help would be appreciated. Thanks.

  • Overwriting arguments object for a Javascript function

    - by Ian Storm Taylor
    If I have the following: // Clean input. $.each(arguments, function(index, value) { arguments[index] = value.replace(/[\W\s]+/g, '').toLowerCase(); }); Would that be a bad thing to do? I have no further use for the uncleaned arguments in the function, and it would be nice not to create a useless copy of arguments just to use them, but are there any negative effects to doing this? Ideally I would have done this, but I'm guessing this runs into problems since arguments isn't really an Array: arguments = $.map(arguments, function(value) { return value.replace(/[\W\s]+/g, '').toLowerCase(); }); Thanks for any input. EDIT: I've just realized that both of these are now inside their own functions, so the arguments object has changed. Any way to do this without creating an unnecessary variable?

  • ASP.Net MVC Outbound Route Matching Problem When Using ActionLink

    - by Godders
    Hi there, Hoping for some help after reading into MVC routing and not coming up with the answer myself. I have the following routes registered: public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( null, "YourFeedback/Article/{resourceId}", new { controller = "YourFeedback", action = "Index", contentTypeId = new Guid(ConfigurationManager.AppSettings["ArticleLibraryId"]) }); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); } I have the following ActionLink in an aspx view: <%=Html.ActionLink("Your Feedback", "Article", "YourFeedback", new { resourceId = Model.ContentId.ResourceId }, new { @class = "yourFeedback" })%> My understanding of MVC routing is that this would render a anchor link with href of "/YourFeedback/Article/101" where 101 comes from Model.ContentId.ResourceId. Yet the anchor link href is rendered as "YourFeedback/Article/resourceId=101". Any ideas where I'm going wrong? Thanks in advance.

  • Is there a name for a language feature that allows assignment/creation?

    - by Alex Mcp
    This is a bit hard for me to articulate, but in PHP you can say something like: $myArray['someindex'] = "my string"; and if there is no index named that, it will create/assign the value, and if there IS an index, it will overwrite the existing value. Compare this to Javascript where today I had to do checks like so: if (!myObject[key]) myObject[key] = "value"; I know this may be a bit of a picky point, but is there a name for the ability of PHP (and many other languages) to do these checks on their own as opposed to the more verbose (read: PITA) method of Javascript?

  • How to prevent direct access to my JSON service?

    - by FrankLy
    I have a JSON web service to return home markers to be displayed on my Google Map. Essentially, http://example.com calls the web service to find out the location of all map markers to display like so: http://example.com/json/?zipcode=12345 And it returns a JSON string such as: {"address": "321 Main St, Mountain View, CA, USA", ...} So on my index.html page, I take that JSON string and place the map markers. However, what I don't want to have happen is people calling out to my JSON web service directly. I only want http://example.com/index.html to be able to call my http://example.com/json/ web service ... and not some random dude calling the /json/ directly. Quesiton: how do I prevent direct calling/access to my http://example.com/json/ web service?

  • convolution in R

    - by user236215
    I tried to do convolution in R directly and using FFTs then taking inverse. But it seems from simple observation it is not correct. Look at this example: # DIRECTLY > x2$xt [1] 24.610 24.605 24.610 24.605 24.610 > h2$xt [1] 0.003891051 0.003875910 0.003860829 0.003845806 0.003830842 > convolve(h2$xt,x2$xt) [1] 0.4750436 0.4750438 0.4750435 0.4750437 0.4750435 # USING INVERSE FOURIER TRANSFORM > f=fft(fft(h2$xt)*fft(x2$xt), inv=TRUE) > Re(f)/length(f) [1] 0.4750438 0.4750435 0.4750437 0.4750435 0.4750436 > Lets take the index 0. At 0, the convolution should simply be the last value of x2$xt (24.610) multiplied by first value of h2$xt (0.003891051) which should give convolution at index 0 = 24.610*0.003891051 = 0.09575877 which is way off from 0.4750436. Am I doing something wrong? Why is the values so different from expected?
