  • No results are returned when using Flickr JSON request

    - by Martijn1981
    I'm still fairly new to AJAX and I'm experimenting with Twitter and Flickr. Twitter is working fine so far, but I've run into some issues with the Flickr API. I'm getting no results back. The URL seems to be working fine and I'm pointing to the right object containing the array ('items'). Can anybody tell me what I'm doing wrong please? Thanks! $('#show_pictures').click(function(e){ e.preventDefault(); $.ajax({ url: 'http://api.flickr.com/services/feeds/photos_public.gne?format=json&jsoncallback=?&tags=home', dataType: 'jsonp', success: function(data) { $.each(data.items, function(i, item){ $('<div></div>') .hide() .append('<h1>'+item.title+'</h1>') .append('<img src="'+item.media.m+'" >') .append('<p>'+item.description+'</p>') .appendTo('#results') .fadeIn(); }) }, error: function(data) { alert('Something went wrong!'); } }); });

  • Django ModelForm Imagefield Upload

    - by Wei Xu
    I am pretty new to Django and I met a problem in handling image upload using ModelForm. My model is as following: class Project(models.Model): name = models.CharField(max_length=100) description = models.CharField(max_length=2000) startDate = models.DateField(auto_now_add=True) photo = models.ImageField(upload_to="projectimg/", null=True, blank=True) And the modelform is as following: class AddProjectForm(ModelForm): class Meta: model = Project widgets = { 'description': Textarea(attrs={'cols': 80, 'rows': 50}), } fields = ['name', 'description', 'photo'] And the View function is: def addProject(request, template_name): if request.method == 'POST': addprojectform = AddProjectForm(request.POST,request.FILES) print addprojectform if addprojectform.is_valid(): newproject = addprojectform.save(commit=False) print newproject print request.FILES newproject.photo = request.FILES['photo'] newproject.save() print newproject.photo else: addprojectform = AddProjectForm() newProposalNum = projectProposal.objects.filter(solved=False).count() return render(request, template_name, {'addprojectform':addprojectform, 'newProposalNum':newProposalNum}) the template is: <form class="bs-example form-horizontal" method="post" action="">{% csrf_token %} <h2>Project Name</h2><br> {{ addprojectform.name }}<br> <h2>Project Description</h2> {{ addprojectform.description }}<br> <h2>Image Upload</h2><br> {{ addprojectform.photo }}<br> <input type="submit" class="btn btn-success" value="Add Project"> </form> Can anyone help me or could you give an example of image uploading? Thank you!

  • Why is my long polling code for a notification system not updating in real time? PHP MYSQL

    - by tjones
    I am making a notification system similar to the red notification on facebook. It should update the number of messages sent to a user in real time. When the message MYSQL table is updated, it should instantly notify the user, but it does not. There does not seem to be an error inserting into MYSQL because on page refresh the notifications update just fine. I am essentially using code from this video tutorial: http://www.screenr.com/SNH (which updates in realtime if a data.txt file is changed, but it is not written for MYSQL like I am trying to do) Is there something wrong with the below code: **Javascript** <script type="text/javascript"> $(document).ready(function(){ var timestamp = null; function waitForMsg(){ $.ajax({ type: "GET", url: "getData.php", data: "userid=" + userid, async: true, cache: false, success: function(data){ var json = eval('(' + data + ')'); if (json['msg'] != "") { $('.notification').fadeIn().html(json['msg']); } setTimeout('waitForMsg()',30000); }, error: function(XMLHttpRequest, textStatus, errorThrown){ setTimeout('waitForMsg()',30000); } }); } waitForMsg(); </script> <body> <div class="notification"></div> **PHP*** <?php if ($_SERVER['REQUEST_METHOD'] == 'GET' ) { $userid = $_GET['userid']; include("config.php"); $sql="SELECT MAX(time) FROM notification WHERE userid='$userid'"; $result = mysql_query($sql); $row = mysql_fetch_assoc($result); $currentmodif = $row['MAX(time)']; $s="SELECT MAX(lasttimeread) FROM notificationsRead WHERE submittedby='$userid'"; $r = mysql_query($s); $rows = mysql_fetch_assoc($r); $lasttimeread = $rows['MAX(lasttimeread)']; while ($currentmodif <= $lasttimeread) { usleep(10000); clearstatcache(); $currentmodif = $row['MAX(time)']; } $response = array(); $response['msg'] = You have new messages; echo json_encode($response); } ?>

  • multiple ajax request to action in asp.net mvc

    - by persian Dev
    I am developing an asp.net mvc application and have ajax calls on my page. Here is a form which I load by ajax call to page : The form is located in a partial view <div id="CreateCultureArea"> <% using (Ajax.BeginForm("CreateCulture", "Admin", new AjaxOptions() { OnSuccess = "handleCreateCulture" })) { %> ..... <% } %> </div> The following script is located in a view $('.CreateCulture').live('click', function (e) { e.preventDefault(); var idval = this.id; $.ajax({ url: "/Admin/CreateCulture", dataType: 'html', data: { id: idval }, success: function (mydata) { $("#CultureContentArea").empty(); $("#CultureContentArea").empty().hide().append(mydata).fadeIn(2000); $("form").removeData("validator"); $("form").removeData("unobtrusiveValidation"); $.validator.unobtrusive.parse("form"); }, type: "GET" }); return false; }) </script> When users click on a link with CreateCulture class, the form is loaded to page. But as I saw the requests in firebug, it calls the action multiple times. I read similar posts like mine on stackoverflow.com and most of them suggested removing repetitive "jquery.unobtrusive-ajax.min.js" calss in page, but as I saw the output page I only see on link to the "jquery.unobtrusive-ajax.min.js" script.

  • Problems with multi-line comments jquery

    - by c0mrade
    Hello, I'm making a image website with a bunch of images on the website, and below every image there is possibility of commenting the image and after that comments gets displayed without page loading and the comment content, the problem is when I have long comments which break the current line they don't get displayed since my comment box css overflow is hidden. Here is example : This is a comment - This is displayed properly This is a comment This is a comment This is a comment - this is not displayed properly since it break line. Here is the jQuery code for this : $.ajax({ type: "POST", url: "<?=base_url()?>imagesform/post_comment", data: datas, success: function () { $("#image-comments-" + image_id).attr("class", "comments"); $("#image-comments-" + image_id).append("<li id=\"new_append_" + image_id+ "\">" + $("#image").find(".comment").val() + "</li>").children(':last').height($('.comments li:last').height()).hide().slideDown(500, function () { var bodyHeight = $('html').height(); $('.addComment').fadeOut(300, function () { $('html').height(bodyHeight); }); }); alert($("#image").find(".comment").val()); } }); Here the $("#image").find(".comment").val() is the value of the text-area in which comment is inputted, when I alert it the whole multi line input is there put its not being appended to the li properly, that is part when I get confused, any suggestions why only part of the inputted string is appended?

  • How can I handle all my errors/messages in one place on an Asp.Net page?

    - by Atomiton
    Hi all, I'm looking for some guidance here. On my site I put things in Web user controls. For example, I will have a NewsItem Control, an Article Control, a ContactForm control. These will appear in various places on my site. What I'm looking for is a way for these controls to pass messages up to the Page that they exist on. I don't want to tightly couple them, so I think I will have to do this with Events/Delegates. I'm a little unclear as to how I would implement this, though. A couple of examples: 1 A contact form is submitted. After it's submitted, instead of replacing itself with a "Your mail has been sent" which limits the placement of that message, I'd like to just notify the page that the control is on with a Status message and perhaps a suggested behaviour. So, a message would include the text to render as well as an enum like DisplayAs.Popup or DisplayAs.Success 2 An Article Control queries the database for an Article object. Database returns an Exception. Custom Exception is passed to the page along with the DisplayAs.Error enum. The page handles this error and displays it wherever the errors go. I'm trying to accomplish something similar to the ValidationSummary Control, except that I want the page to be able to display the messages as the enum feels fit. Again, I don't want to tightly bind or rely a control existing on the Page. I want the controls to raise these events, but the page can ignore them if it wants. Am I going about this the right way? I'd love a code sample just to get me started. I know this is a more involved question, so I'll wait longer before voting/choosing the answers.

  • Updating table row by given id with jQuery

    - by fabrik
    Hello all! I need to update a specific table row (via tr id="unique_key") after a successful AJAX call. HTML fragment: <a name=\"p{$product_id}\" class=\"tr{$product_id}\"></a> <tr id="p{product_id}" class="item-row"> <td><h3>{product_id}</h3><a rel="facebox" href="ajax_url">{product_name}</a></td> <td>{image_information}</td> <td>{image_sortiment}</td> <td>{product_status}</td> </tr> Javascript: // AJAX Call success: function(msg){ $('#p' + prod_id).remove(); $('.tr' + prod_id).after(msg); $('#p' + prod_id + ' a[rel*=facebox]').facebox(); } ... What happens: The table row removed Anchors grouped into one single row (not before their <tr>'s) so my 'hook' disappears AJAX result inserted over the whole table (after my 'hook' but still a wrong place) What's wrong with my idea? How can i force jQuery to 'overwrite' the required table row?

  • Android app with library can't find the library.apk

    - by Dean Schulze
    I'm trying to get the FinchVideo example from the Programming Android book to work. It uses the FinchWelcome library. I've set up FinchWelcome as a Library and in the FinchVideo application I have checked the FinchWelcome library in Properties - Android. When I try to run FinchVideo in the emulator it complains that it cannot find FinchWelcome.apk (output below). I'm building for Android 4.0.3. While Googling for this problem I've found that a lot of people have this problem with Android apps that use libraries. No one seems to have found a solution that works consistently, though. None of the Android books I've seen even talk about how to download libraries. What is the proper way to handle libraries in Android applications? Is this a bug in the Eclipse ADT? Thanks.

    - by Sisir
    Ok, Here we go. I have already searched the Stack for the answer i have found some useful info but i want to clear up some more things. I also search the net for the answer but no real help. I have worked with some api (yelp, ouside.in). In yelp i use to inject the script to head with the url request to the api with a callback funcion. I worked fine in all browsers. But while using outside.in api when i call the url the callback in not working. In yelp they have a url field can be used like that callback=callbackfuncion so the callback will automatically called. But in outside.in there is not such field available. Is there are any standard command for callback function which will work regardless of any server/api? I also tried a standard ajax request using jQuery $.ajax() function. It worked for my local pc for both IE and other browser but did not working in IE showing the error: access denied, other borwser seems ok. Firebug in my FF also don't notice any errors. Outside.in has an javascript example but it is too hard to me to understand github.com/outsidein/api-examples/tree/master/javascript/browser/ site i am working: http://citystir.com yelp: yelp.com outside.in: outside.in Techniqual info: i am using: wampserver in local, wordpress for hosting, Godaddy, apache for remote with linux.

  • Execute JavaScript from within a C# assembly

    - by ScottKoon
    I'd like to execute JavaScript code from within a C# assembly and have the results of the JavaScript code returned to the calling C# code. It's easier to define things that I'm not trying to do: I'm not trying to call a JavaScript function on a web page from my code behind. I'm not trying to load a WebBrowser control. I don't want to have the JavaScript perform an AJAX call to a server. What I want to do is write unit tests in JavaScript and have then unit tests output JSON, even plain text would be fine. Then I want to have a generic C# class/executible that can load the file containing the JS, run the JS unit tests, scrap/load the results, and return a pass/fail with details during a post-build task. I think it's possible using the old ActiveX ScriptControl, but it seems like there ought to be a .NET way to do this without using SilverLight, the DLR, or anything else that hasn't shipped yet. Anyone have any ideas? update: From Brad Abrams blog namespace Microsoft.JScript.Vsa { [Obsolete("There is no replacement for this feature. Please see the ICodeCompiler documentation for additional help. http://go.microsoft.com/fwlink/?linkid=14202")] Clarification: We have unit tests for our JavaScript functions that are written in JavaScript using the JSUnit framework. Right now during our build process, we have to manually load a web page and click a button to ensure that all of the JavaScript unit tests pass. I'd like to be able to execute the tests during the post-build process when our automated C# unit tests are run and report the success/failure alongside of out C# unit tests and use them as an indicator as to whether or not the build is broken.

  • Jquery UI dialog does not disappear

    - by iamrohitbanga
    I am using jquery-ui tabs and dialog functionality. Each tab has a button on the page which opens a dialog. This works for one of the tabs. However if I go the second tab, the button does not work there. When I come back to the first tab, the dialog does show up but the problem is I notice as I make switches back and forth to the first tab, it keeps on inserting new div's while the old div's have display:none set on them. I am doing this using JSP. This is how the reusable jsp looks like: <script> $(function() { var formData = null; $.ajax({ url : "addFormGenerator.html", success : function(data) { formData = data; $("#addFormDialog").html(data); $("#addFormDialog").dialog({ autoOpen : false, height : 300, width : 350, modal : true, buttons : { "Add" : function() { $(this).dialog("close"); }, Cancel : function() { $(this).dialog("close"); } }, close : function() { } }); } }); $("#addButton").button().click(function() { $("#addFormDialog").html(formData); $("#addFormDialog").dialog("open"); }); }); </script> <button id="addButton">Click here to Add New</button> <div id="addFormDialog" title="Add New"></div> This jsp fragment is included in other jsp pages as well. I was assuming as I switch between tabs the old button will be garbage collected. Can you help me understand the problem and fix it?

    Working with OpenSceneGraph, and I keep running into this violation issue that I would appreciate some help with. The problem is with the particular line below which happens to be the first in my main function. osg::ref_ptr<osg::Node> bench = osgDB::readNodeFile("Models/test.IVE"); I have my models folder right in my directory.

  • Error with threads during automatic testing on TeamCity 5

    - by yeyeyerman
    Hello, I'm having some problems executing the tests of the application I'm developing. All the tests execute normally with ReSharper and in NCover. However, the execution of one of these tests in TeamCity is generating an error. This test initializes two objects, the object under test and a simulator of a real object. Both objects will communicate throug a serial link in a representation of the real scenario. ObjectSimulator r_simulator = new ObjectSimulator(...); ObjectDriver r_driver = new ObjectDriver(...); Assert.IsTrue(r_driver.Connect() == ErrorCode.Success); The simulator just do the following in the constructor public class ObjectSimulator { ... public ObjectSimulator() { // serial port configuration m_port = new SerialPort(); m_port.DataReceived += DataReceivedEvent; } ... } The main object has two threads. The main thread of the application and a timer to refresh a watchdog timer in the real object. public ErrorCode Connect() { ... StartSynchroTimer(); Thread.Sleep(4); // to check if the timer is working properly ... } The problem is comming from the Thread.Sleep() call, as when I remove it everything works. It seems like the ObjectSimulator also sleeps and doesn't receive the DataReceived event. How can I resolve this issue?

  • Stopping process in /etc/inittab kills spawned process. Doesn't happen in rc.local.

    - by Paul
    Hi, I'm trying to execute a firmware upgrade while my programming is running in inittab. My program will run 2 commands. One to extract the installer script from the tarball and the other to execute the installer script. In my code I'm using the system() function call. These are the 2 command strings below, system ( "tar zvxf tarball.tar.gz -C / installer.sh 2>&1" ); system( "nohup installer.sh tarball >/dev/null 2>&1 &" ); The installer script requires the tarball to be an argument. I've tried using sudo but i still have the same problem. I've tried nohup with no success. The installer script has to kill my program when doing the firmware upgrade but the installer script will stay alive. If my program is run from the command line or rc.local, on my target device, my upgrade works fine, i.e. when my program is killed my installer script continues. But I need to run my program from /etc/inittab so it can respawn if it dies. To stop my program in inittab the installer script will hash it out and execute "telinit q". This is where my program dies (but thats what I want it to do), but it also kills my installer script. Does anyone know why this is happening and what can I do to solve it? Thanks in advance.

  • Optimization of a c++ matrix/bitmap class

    - by Andrew
    I am searching a 2D matrix (or bitmap) class which is flexible but also fast element access. The contents A flexible class should allow you to choose dimensions during runtime, and would look something like this (simplified): class Matrix { public: Matrix(int w, int h) : data(new int[x*y]), width(w) {} void SetElement(int x, int y, int val) { data[x+y*width] = val; } // ... private: // symbols int width; int* data; }; A faster often proposed solution using templates is (simplified): template <int W, int H> class TMatrix { TMatrix() data(new int[W*H]) {} void SetElement(int x, int y, int val) { data[x+y*W] = val; } private: int* data; }; This is faster as the width can be "inlined" in the code. The first solution does not do this. However this is not very flexible anymore, as you can't change the size anymore at runtime. So my question is: Is there a possibility to tell the compiler to generate faster code (like when using the template solution), when the size in the code is fixed and generate flexible code when its runtime dependend? I tried to achieve this by writing "const" where ever possible. I tried it with gcc and VS2005, but no success. This kind of optimization would be useful for many other similar cases.

  • shorten something in AS 2.0 using eval or set?

    - by chris
    eval("_parent.volumetone" + target1)._yscale = Math.round(number)/1.5+50; eval("_parent.volumetone" + target2)._yscale = Math.round(number)/1.5+50; eval("_parent.volumetone" + target3)._yscale = Math.round(number)/1.5+50; eval("_parent.volumetone" + target4)._yscale = Math.round(number)/1.5+50; eval("_parent.volumetone" + target5)._yscale = Math.round(number)/1.5+50; eval("_parent.volumetone" + target6)._yscale = Math.round(number)/1.5+50; eval("_parent.volumetone" + target7)._yscale = Math.round(number)/1.5+50; eval("_parent.volumetone" + target8)._yscale = Math.round(number)/1.5+50; eval("_parent.volumetone" + target9)._yscale = Math.round(number)/1.5+50; eval("_parent.volumetone" + target10)._yscale = Math.round(number)/1.5+50; eval("_parent.volumetone" + target11)._yscale = Math.round(number)/1.5+50; eval("_parent.volumetone" + target12)._yscale = Math.round(number)/1.5+50; eval("_parent.volumetone" + target13)._yscale = Math.round(number)/1.5+50; eval("_parent.volumetone" + target14)._yscale = Math.round(number)/1.5+50; eval("_parent.volumetone" + target15)._yscale = Math.round(number)/1.5+50; i have these lines of repetitive code. the variables target1 to target15 are a random number between 1 and 110. so one may point to _parent.volumetone49 and adjust its _yscale for example. the code above works the way i want, but i want it shorter. here's something i tried with no success: for (i = 0; i < 15; i++) { set("_parent.volumetone" + ("target"+i) + "._xscale", Math.round(funhousenumber)/1.5+50); } basically having a loop that starts at 1 and goes to 15, then replaces target1 with target+i, i being 1, which would give target1 and thus the number contained in it. maybe i have to use eval()? i'm still not sure what i'm doing but i'm learning as i go. thanks.

  • jQuery adding a function to a link question

    - by wali
    Hello all, I have a dynamically created table which in the last <td> there is a hidden <div> which is shown when the user hovers over a link in the <td>. That all works fine but there are several links in the div that I want to fire a function based on the id of the link concat'd with an string captured from a <td> from the parent row. I can capture the the variables I need from the id and <td> but something is wrong with the click function I have created. I monitored the function in FireBug and the function appears to be firing on all of the links instead of the one that is clicked. Here is my working code: function fixLink() { $('a.batchMatchLink').click( function() { var r = $(this).parent().parent().parent().parent().parent(); var x = $(this).attr("id"); var a = $(r).find('td:nth-child(6)').text(); var st = x + "." + a; fireLink(st); } ); } function fireLink(st) { $.ajax({ type: "POST", url: "AjaxWcf.svc/MatchBatch", contentType: "application/json; charset=utf-8", data: st, dataType: "json", success: function(msg) { alert("Entry has been updated"); }, error: AjaxFailed }); Why are all of the links firing? Thanks!!!

  • jQuery and MySQL

    - by Wayne
    I have taken a jQuery script which would remove divs on a click, but I want to implement deleting records of a MySQL database. In the delete.php: <?php $photo_id = $_POST['id']; $sql = "DELETE FROM photos WHERE id = '" . $photo_id . "'"; $result = mysql_query($sql) or die(mysql_error()); ?> The jQuery script: $(document).ready(function() { $('#load').hide(); }); $(function() { $(".delete").click(function() { $('#load').fadeIn(); var commentContainer = $(this).parent(); var id = $(this).attr("id"); var string = 'id='+ id ; $.ajax({ type: "POST", url: "delete.php", data: string, cache: false, success: function(){ commentContainer.slideUp('slow', function() {$("#photo-" + id).remove();}); $('#load').fadeOut(); } }); return false; }); }); The div goes away when I click on it, but then after I refresh the page, it appears again... How do I get it to delete it from the database? Thanks :) EDIT: Woopsie... forgot to add the db.php to it, so it works now .<

  • how to install a file handle in perl class

    - by Haiyuan Zhang
    please looku up the following code first. #! /usr/bin/perl package foo; sub new { my $pkg = shift; my $self = {}; my $self->{_fd} = undef; bless $self, $pkg; return $self; } sub Setfd { my $self = shift; my $fd = shift; $self_->{_fd} = $fd; } sub write { my $self = shift; print $self->{_fd} "hello word"; } my $foo = new foo; My intention is to store a file handle within a class using hash. the file handle is undefined at first, but can be initilized afterwards by calling Setfd function. then write can be called to actually write string "hello word" to a file indicated by the file handle, supposed that the file handle is the result of a success "write" open. but, perl compiler just complains that there are syntax error in the "print" line. can anyone of you tells me what's wrong here? thanks in advance.
