  • using jquery $.ajax to retrieve data and push data into javascript array through the success functio

    - by teamdane
    Hello All, I have a function that I'm trying to retrieve values using $.ajax and push the returned data into an array called output. Problem is the success function will not allow me to push the results into the array. see below for code. var getValues = function(el) { var value = ($(el).val()); if(value == '' || $(el).attr('disabled')) { return []; } var string = 'value=' + value; var output = []; $.ajax({ type: "GET", url: 'shocklookup_callback.php', dataType: "string", data: string, success: function(data) { } }); //output.push({ text : value + 'test', value : value + 'test1'} ); return output; }; Any ideas of what I can put in the success function to be able to push the data into the output array? Also I need to be able to return the output array to the original function getValues. If this doesn't' make a whole lot of sense please let me know and I'll try to explain better. Thanks, Dane

  • C# generics with MVVM, pulling the T out of <T>

    - by bufferz
    My Model is a generic class that contains a (for example) Value property which can be int, float, string, bool, etc. So naturally this class is represented something like Model<T>. For the sake of collections Model<T> implements the interface IModel, although IModel is itself empty of any content. My ViewModel contains and instance of Model<T> and it is passed in through ViewModel's constructor. I still want to know what T is in ViewModel, so when I expose Model to the View I know the datatype of Model's buried Value property. The class for ViewModel ends up looking like the following: class ViewModel<T> { private Model<T> _model; public ViewModel(Model<T> model) { ....blah.... } public T ModelsValue {get; set; } } This works fine, but is limited. So now I need to expose a collection of IModels with varying Ts to my View, so I'm trying to set up an ObservableCollection of new ViewModel<T>s to a changing list of IModels. The problem is, I can't figure out how to get T from Model<T> from IModel to construct ViewModel<T>(Model<T>) at runtime. In the VS2010 debugger I can mouseover any IModel object and see its full Model<int> for example at runtime so I know the data is in there. Any ideas?

  • Copy object using pointer (templates)

    - by Azodious
    How the push_back of stl::vector is implemented so it can make copy of any datatype .. may be pointer, double pointer and so on ... I'm implementing a template class having a function push_back almost similar to vector. Within this method a copy of argument should be inserted in internal memory allocated memory. but the argument is a pointer. (an object pointer). Can you pls tell how to create copy from pointer. so that if i delete the pointer in caller still the copy exists in my template class? Code base is as follows: template<typename T> class Vector { public: void push_back(const T& val_in) { T* a = *(new T(val_in)); m_pData[SIZE++] = a; } } Caller: Vector<MyClass*> v(3); MyClass* a = new MyClass(); a->a = 0; a->b = .5; v.push_back(a); delete a; Thanks.

  • Is it possible to send back a json array along with seperate variables

    - by Scarface
    Hey guys I have an ajax jquery function that receives data from a php script. I want to return an array with all the online users which is retrieved from a mysql statement, and I want to send other separate variables I need for other purposes along with it. If anyone has any ideas, I would greatly appreciate it. NOTE: the example below is to illustrate what I want to do, I understand that json-encoding the array with other variables is dysfunctional. JQUERY $.ajax({ type: "POST", data: "parameters", url: "retrieval.php", dataType: 'json', success: function(json) { $('#div1').html(json.array); $('#div2').html(json.variable1); $('#div3').html(json.variable2); } }) PHP $qryuserscount1="SELECT * FROM active_users"; $userscount1=mysql_query($qryuserscount1); while ($row = mysql_fetch_array($userscount1)) { $onlineuser= $row['username']; $id=$row['id']; $data[]=$onlineuser.$id; //for example there are 3 users, should send 3 entries back } $data['variable1']='something'; $data['variable2']='something else'; $out = json_encode($data); print $out;

  • Asynchronous Controller is blocking requests in ASP.NET MVC through jQuery

    - by Jason
    I have just started using the AsyncController in my project to take care of some long-running reports. Seemed ideal at the time since I could kick off the report and then perform a few other actions while waiting for it to come back and populate elements on the screen. My controller looks a bit like this. I tried to use a thread to perform the long task which I'd hoped would free up the controller to take more requests: public class ReportsController : AsyncController { public void LongRunningActionAsync() { AsyncManager.OutstandingOperations.Increment(); var newThread = new Thread(LongTask); newThread.Start(); } private void LongTask() { // Do something that takes a really long time //....... AsyncManager.OutstandingOperations.Decrement(); } public ActionResult LongRunningActionCompleted(string message) { // Set some data up on the view or something... return View(); } public JsonResult AnotherControllerAction() { // Do a quick task... return Json("..."); } } But what I am finding is that when I call LongRunningAction using the jQuery ajax request, any further requests I make after that back up behind it and are not processed until LongRunningAction completes. For example, call LongRunningAction which takes 10 seconds and then call AnotherControllerAction which is less than a second. AnotherControllerAction simply waits until LongRunningAction completes before returning a result. I've also checked the jQuery code, but this still happens if I specifically set "async: true": $.ajax({ async: true, type: "POST", url: "/Reports.aspx/LongRunningAction", dataType: "html", success: function(data, textStatus, XMLHttpRequest) { // ... }, error: function(XMLHttpRequest, textStatus, errorThrown) { // ... } }); At the moment I just have to assume that I'm using it incorrectly, but I'm hoping one of you guys can clear my mental block!

  • Hibernate saveOrUpdate problem on char data type

    - by Yashwant Chavan
    Hi I am using Hibernate 3.0 , facing issue related to the char datatype field. I am trying to save Client pojo in the database, using following method. Problem is my client_id field is char(10) in the database. when client_id is 10 characters it works fine. but when client_id is less than ten characters it gives problem at the time of update. Rather than updating data it try to insert cleint record again and gives the unquie key exeception. i drill down the problem because of char(10) client_id field. it keeps space after client_id value upto 10 characters. Is there is any confuguration to overcome this problem. rather than modifying client_id to varchar2. public boolean saveClient(Clnt client) { boolean lReturnValue = false; SessionFactory sessionFactory = null; Session session = null; Transaction transaction = null; try { HibernateTemplate hibernateTemplate = getHibernateTemplate(); sessionFactory = hibernateTemplate.getSessionFactory(); session = sessionFactory.getCurrentSession(); transaction = session.beginTransaction(); session.saveOrUpdate(client); transaction.commit(); lReturnValue = true; } catch (HibernateException e) { lReturnValue = false; // TODO Auto-generated catch block if (transaction != null) { transaction.rollback(); } e.printStackTrace(); } return lReturnValue; }

  • Optimize jQuery code

    - by Dannemannen
    Greetings, Just built some stuff with jQuery, everything works perfect(!), but I would like it to be as optimzed as possible.. what small changes can I do to my code? $(document).ready(function() { // hide the indicator, we use it later $(".indicator").hide(); // start the animation of the progressbar $(".fill").animate({ width: "50px",}, 4000, function() { $(".indicator").effect("pulsate", { times:999 }, 2000);}); // notify-me ajax function $(".btn-submit").click(function() { // get the variable email and put it in a new variable var email = $("input#mail").val(); var dataString = 'mail='+email; $.ajax({ type: "POST", url: "/mail.php", data: dataString, dataType: "json", success: function(msg){ // JSON return, lets do some magic if(msg.status == "ok") { $("#response-box").fadeIn("slow").delay(2000).fadeOut("slow"); $("#fade").fadeIn("slow").delay(2000).fadeOut("slow"); $("#response-box .inner").html("<h1>Thank you.</h1>We'll keep in touch!"); $("#mail").val("e.g. [email protected]"); } else { $("#response-box").fadeIn("slow").delay(2000).fadeOut("slow"); $("#fade").fadeIn("slow").delay(2000).fadeOut("slow"); $("#response-box .inner").html("<h1>Oops.</h1>Please try again!"); } } }); //make sure the form doesn't post return false; }); });

  • Problem with using Jquery.ajax over .load on Zend

    - by Matthew
    Right now, what i'm trying to do is to replace a label on the front page with a block of html. Right now, the page basically has: <label id="replace"></label> the js currently has: $(document).ready(function(){ $("#replace").load('/test'); }); the Zend class function has: public function indexAction(){ $this->_helper->layout()->disableLayout(); $this->_view->message = "This is from TestController index"; } and finally the index.phtml template simply has: <?php echo $this->message;?> Right now, I want to change the code around so that instead of just replacing that label with the same message, it would do a POST where the function will pull out a parameter, do something (like for instance, go to the database and pull something out with the POST parameter) and then return the message. I've tried editing the js so that it would look like: $.post('/test', {param : "test_param"}, function(data) {$("#replace").html(data);}); or $.ajax({ type: 'POST', url: '/test', data: "{param:test_param}", contentType: "application/json; charset=utf-8", dataType: "json", success: function(data) {$("#replace").html(data);} }); and neither worked. I took a step back and tried to replicate the .load functionality and do: $.ajax({ url: '/test', success: function(data) { $('#replace').html(data); alert('Load was performed.'); } }); and it doesn't work either. Anyone have any tips on how to go about doing this?

  • jQuery: responding to click event of element added to document after page load

    - by morpheous
    I am writing a page which uses a lot of in situ editing and updating using jQuery for AJAX. I have come accross a problem which can best be summarised by the workflow described below: Clicking on 'element1' on the page results in a jQuery AJAX POST Data is received in json format The data received in json format The received data is used to update an existing element 'results' in the page The received data is actual an HTML form I want jQuery to be responsible for POSTing the form when the form button is clicked The problem arises at point 6 above. I have code in my main page which looks like this: $(document).ready(function(){ $('img#inserted_form_btn').click(function(){ $.ajax({'type: 'POST', 'url': 'www.example.com', function($data){ $(data.id).html($data.frm); }), 'dataType': 'json'} }); }); However, the event is not being triggered. I think this is because when the document is first loaded, the img#inserted_form_btn element does not exist on the page (it is inserted into the DOM as the result of an element being clicked on the page (not shown in the code above - to keep the question short) My question therefore is: how can I get jQuery to be able to respond to events occuring in elements that were added to the DOM AFTER the page has loaded?

  • std::map keys in C++

    - by Soumava
    I have a requirement to create two different maps in C++. The Key is of type CHAR * and the Value is a pointer to a struct. I am filling 2 maps with these pairs, in separate iterations. After creating both maps I need find all such instances in which the value of the string referenced by the CHAR * are same. For this i am using the following code : typedef struct _STRUCTTYPE { .. } STRUCTTYPE, *PSTRUCTTYPE; typedef pair {CHAR *,PSTRUCTTYPE} kvpair; .. CHAR *xyz; PSTRUCTTYPE abc; after filling the information; Map.insert (kvpair(xyz,abc)); the above is repeated x times for the first map, and y times for the second map. after both are filled out; std::map {CHAR *, PSTRUCTTYPE} :: iterator Iter,findIter; for (Iter=iteratedMap-begin();Iter!=iteratedMap-end();mapIterator++) { char *key = Iter-first; printf("%s\n",key); findIter=otherMap-find(key); //printf("%u",findIter-second); if (findIter!=otherMap-end()) { printf("Match!\n"); } } The above code does not show any match, although the list of keys in both maps show obvious matches. My understanding is that the equals operator for CHAR * just equates the memory address of the pointers. My question is, what should i do to alter the equals operator for this type of key or could I use a different datatype for the string? *note : {} has been used instead of angle brackets as the content inside angle brackets was not showing up in the post.

  • Implementing comparision operators via 'tuple' and 'tie', a good idea?

    - by Xeo
    (Note: tuple and tie can be taken from Boost or C++11.) When writing small structs with only two elements, I sometimes tend to choose a std::pair, as all important stuff is already done for that datatype, like operator< for strict-weak-ordering. The downsides though are the pretty much useless variable names. Even if I myself created that typedef, I won't remember 2 days later what first and what second exactly was, especially if they are both of the same type. This gets even worse for more than two members, as nesting pairs pretty much sucks. The other option for that is a tuple, either from Boost or C++11, but that doesn't really look any nicer and clearer. So I go back to writing the structs myself, including any needed comparision operators. Since especially the operator< can be quite cumbersome, I thought of circumventing this whole mess by just relying on the operations defined for tuple: Example of operator<, e.g. for strict-weak-ordering: bool operator<(MyStruct const& lhs, MyStruct const& rhs){ return std::tie(lhs.one_member, lhs.another, lhs.yet_more) < std::tie(rhs.one_member, rhs.another, rhs.yet_more); } (tie makes a tuple of T& references from the passed arguments.) Edit: The suggestion from @DeadMG to privately inherit from tuple isn't a bad one, but it got quite some drawbacks: If the operators are free-standing (possibly friends), I need to inherit publicly With casting, my functions / operators (operator= specifically) can be easily bypassed With the tie solution, I can leave out certain members if they don't matter for the ordering Are there any drawbacks in this implementation that I need to consider?

  • Redirection Still not working (updated on earlier question)

    - by NoviceCoding
    So earlier I asked this question: JQuery Login Redirect. Code Included The php file is sending the following: $return['error'] = false; $return['msg'] = 'You have successfully logged in!!'; I've tried all the suggestions, quoting the error on php and ajax end, 2 equals instead of 3, I've also tried DNE true which should be the same as an else statement: $(document).ready(function(){ $('#submit').click(function() { $('#waiting').show(500); $('#empty').show(500); $('#reg').hide(0); $('#message').hide(0); $.ajax({ type : 'POST', url : 'logina.php', dataType : 'json', data: { type : $('#typeof').val(), login : $('#login').val(), pass : $('#pass').val(), }, success : function(data){ $('#waiting').hide(500); $('#empty').show(500); $('#message').removeClass().addClass((data.error === true) ? 'error' : 'success') .text(data.msg).show(500) if(data.error != true) window.location.replace("http://blahblah.com/usercp.php"); if (data.error === true) $('#reg').show(500); $('#empty').hide() }, error : function(XMLHttpRequest, textStatus, errorThrown) { $('#waiting').hide(500); $('#message').removeClass().addClass('error') .text("There was an Error. Please try again.").show(500); $('#reg').show(500); $('#empty').hide(); Recaptcha.reload(); } }); return false; }); And it still wont work. Any ideas on how to make a redirection work if login is successful and error returns false? Also while I am asking, can I put a .delay(3000) 3s at the end of window.location.replace("http://blahblah.com/usercp.php")?

  • Safe json parsing with jquery?

    - by user246114
    Hi, I am using jquery with json. My client pages generate json, which I store on my server. The clients can then fetch the json back out later, parse, and show it. Since my clients are generating the json, it may not be safe. I think jquery uses eval() internally. Is that true? Is there a way to use the native json parsers from the browsers where available, otherwise fall back to manual parsing if not? I'm new to jquery so I don't know where I'd insert my own parsing code. I'm doing something like: $.ajax({ url: 'myservlet', type: 'GET', dataType: 'json', timeout: 1000, error: function(){ alert('Error loading JSON'); }, success: function(json){ alert("It worked!: " + json.name + ", " + json.grade); } }); so in the success() method, the json object is already parsed for me. Is there a way to catch it as a raw string first? Then I can decide whether to use the native parsers or manual parsing (hoping there's a jquery plugin for that..). The articles I'm reading are all from different years, so I don't know if jquery has already abandoned eval() already for json, Thank you

  • Major JQuery bug on IE not reproducible - What can i do in this situation to solve this bug?

    - by ming yeow
    I am hoping to get some help on this issue. Some users on IE have been reporting this javascript issue, but I have been unable to re-produce it. In essence, for some class of windows IE users, the game doesn't work (or $.ajax() is not working). What I know: I swapped out an ajax call (ajax_init_trainer) and used a standard link with some request parameters to do the initialization and ppl seemed to get passed the problem until they hit the next ajax call. I read somewhere that IE does crazy caching so you need to make the urls unique, which is why i added the _requestno parameter. However, setting the cache:false is said to also do this. This didn't fix it for someone who was complaining. function done(res, status) { var data = JSON.parse(res.responseText); hide_loading(); if (status == "success") { window.location.href="/bamo/battle/?{{ fb_sig}}"; } else { display_alert("Problem!",data.msg,$("#notifications")); } }; $(".monster_select_class").click(function() { $(this).attr("src","{{MEDIA_URL}}/bamo/button_select_click.png"); monster_class = $(this).attr("monster_class"); monster_type = $(this).attr("monster_type"); ajax_init_trainer(monster_class,monster_type); }); function ajax_init_trainer(trainer_class,monster_type) { var data = {trainer_class:trainer_class,monster_type:monster_type}; var d = new Date(); var args = { type:"POST",url:"/bamo/api/init_trainer/?_requestno="+d.getTime(),data:data,contentType:"application/json;", dataType: "json",cache:false,complete:done}; $.ajax(args); return false; };

  • Why ajax doesn't work unless I refresh or use location.href?

    - by Connor Tang
    I am working on a html project, which will eventually package by Phonegap. So I am trying to encode the data from html form to JSON format, then use ajax send to a php file resides on server, and receive the response to do something else. Now I use <a href='login.html'> in my index.html to open the login page. In my login page, I have this <script> $(document).ready(function(e) { $('#loginform').submit(function(){ var jData = { "email": $('#emailLogin').val(), "password": $('#Password').val()}; $.ajax({ url: 'PHP/login.php', type:'POST', data: jData, dataType: 'json', async: false, error: function(xhr,status){ //reload(); location.href='index.html'; alert('Wrong email and password'); }, success: function(data){ if(data[1] == 1){ var Id_user = data[0]; location.href='loginSuccess.html'; } } }); }); }); </script> to send my data to server. But I found that it won't work, it's still in the login page. I tried to enter data and submit again, it's still nothing happen. Until I refresh the login page and enter data again, it can give an error message or go to the loginsuccess page. However, when I use <script> function loadLogin(){ location.href='login.html'; } </script> to open the login page, everything works well. So what cause this? How can I modify this piece of code to make it better?

Any suggestion how to get this done.......

  • What am I doing wrong with my ItemsControl & databinding?

    - by Joel
    I'm reworking my simple hex editor to practice using what I've recently learned about data binding in WPF. I'm not sure what I'm doing wrong here. As I understand it, for each byte in the collection "backend" (inherits from ObservableCollection), my ItemsControl should apply the DataTemplate under resources. This template is just a textbox with a binding to a value converter. So I'm expecting to see a row of textboxes, each containing a string representation of one byte. When I use this XAML, all I get is a single line of uneditable text, which as far as I can tell doesn't use a textbox. What am I doing wrong? I've pasted my XAML in below, with the irrelevant parts (Menu declaration, schema, etc) removed. <Window ...> <Window.Resources> <local:Backend x:Key="backend" /> <local:ByteConverter x:Key="byteConverter" /> <DataTemplate DataType="byte"> <TextBox Text="{Binding Converter={StaticResource byteConverter}}" /> </DataTemplate> </Window.Resources> <StackPanel> <ItemsControl ItemsSource="{Binding Source={StaticResource backend}}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <WrapPanel /> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> </StackPanel> </Window>

  • "render as JSON" is display JSON as text instead of returning it to AJAX call as expected

    - by typoknig
    I'm navigating to the index action of MyController. Some of the on the index page I'm making an AJAX call back to myAction in MyController. I expect myAction action to return some data as JSON to my AJAX call so I can do something with the data client side, but instead of returning the data as JSON like I want, the data is being displayed as text. Example of my Grails controller: class MyController { def index() { render( view: "myView" ) } def myAction { def mapOfStuff = [ "foo": "foo", "bar":] render mapOfStuff as JSON } } Example of my JavaScript: $( function() { function callMyAction() { $.ajax({ dataType: 'json', url: base_url + '/myController/myAction', success: function( data ) { $(function() { if( data.foo ) { alert( data.foo ); } if( data.bar ) { alert( data.bar ); } }); } }); } }); What I expect is that my page will render, then my JavaScript will be called, then two alerts will display. Instead the JSON array is displayed as text in my browser window: {"foo":"foo","bar":"bar"} At this point the last segment of the URL in my address bar is myAction and not index. Now if I manually enter the URL of the index page and press refresh, all works as expected. I have half a dozen AJAX calls I do the exact same way and none of them are having problems. What is the deal here? UPDATE: I have noticed something. When I set a break point in the index action of MyController and another one in the myAction action, the break point in myAction gets hit BEFORE the break point in index, even though I am navigating to the index. This is obviously closer to the root cause of my problem, but why is it happening?

  • Processing data from an AJAX request

    - by Josh K
    I have a PHP API I'm working with that outputs everything as JSON. I need to call one of the API methods and parse it out using an AJAX request. I am using jQuery (though it shouldn't matter). When I make the request it errors out with a "parsererror" as the textStatus and a "Syntax Error: invalid label" when I make the request. Simplified code: $.ajax ({ type: "POST", url: "http://mydomain.com/api/get/userlist/"+mid, dataType: "json", dataFilter: function(data, type) { /* Here we assume and pray */ users = eval(data); alert(users[1].id); }, success: function(data, textStatus, XMLHttpRequest) { alert(data.length); // Should be an array, yet is undefined. }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert(textStatus); alert(errorThrown); }, complete: function(XMLHttpRequest, textStatus) { alert("Done"); } }); If I leave off the eval(data) then everything works fine. Well, except for data still being undefined in success. Note that I'm taking an array of objects in PHP and then passing them out through json_encode. Would that make any difference? There has been no progress made on this. I'm willing to throw more code up if someone believes they can help. Here is the PHP side of things private function _get_user_colors($id) { $u = new User(); $u->get_where(array('id' => $id)); $bar = array(); $bar['user'] = $u->stored; foreach($user->colors as $color) { $bar['colors'][] = $color; } echo(json_encode($bar)); } I have had zero issues using this with other PHP based scripts. I don't know why Javascript would take issue with it.

  • jquery dialog calls a server side method with button parameters

    - by Chiefy
    Hello all, I have a gridview control with delete asp:ImageButton for each row of the grid. What I would like is for a jquery dialog to pop up when a user clicks the delete button to ask if they are sure they want to delete it. So far I have the dialog coming up just fine, Ive got buttons on that dialog and I can make the buttons call server side methods but its getting the dialog to know the ID of the row that the user has selected and then passing that to the server side code. The button in the page row is currently just an 'a' tag with the id 'dialog_link'. The jquery on the page looks like this: $("button").button(); $("#DeleteButton").click(function () { $.ajax({ type: "POST", url: "ManageUsers.aspx/DeleteUser", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", success: function (msg) { // Replace the div's content with the page method's return. $("#DeleteButton").text(msg.d); } }); }); // Dialog $('#dialog').dialog({ autoOpen: false, width: 400, modal: true, bgiframe: true }); // Dialog Link $('#dialog_link').click(function () { $('#dialog').dialog('open'); return false; }); The dialog itself is just a set of 'div' tags. Ive thought of lots of different ways of doing this (parameter passing, session variable etc...) but cant figure out how to get any of them working. Any ideas are most welcome As always, thanks in advance to those who contribute.

  • jQuery ajax request response is empty in Internet Explorer

    - by Aprilia1982
    Hi, I'm doing the following ajax call: //exif loader function LoadExif(cImage) { $.ajax({ type: "POST", url: "http://localhost:62414/Default1.aspx/GetImageExif", data: "{iCurrentImage:" + cImage + "}", contentType: "application/json; charset=utf-8", dataType: "json", error: ajaxFailed, success: function (data, status) { var sStr = ''; for (var count in data.d) { sStr = sStr + data.d[count]; }; alert(sStr); } }); }; In Firefox the request works really fine. When I try to run the code in Internet Explorer, the response is empty. Here is the webmethod witch is called: <WebMethod()> _ <ScriptMethod(ResponseFormat:=ResponseFormat.Json)> _ Public Shared Function GetImageExif(ByVal iCurrentImage As Integer) As String Dim sbTable As New StringBuilder sbTable.AppendLine("<table>") sbTable.AppendLine("<tr>") sbTable.AppendLine("<td>Name</td><td>" & gGallery.Images(iCurrentImage).File.Name & "</td>") sbTable.AppendLine("</tr>") sbTable.AppendLine("</table>") Return sbTable.ToString End Function Any ideas?
