  • jquery slideDown menu

    - by Elliott
    Hi, I have a link which once hovered over a box below slides down, once hover is removed it slides back up. I have it working almost to how I want, although in IE8 (Havent tested in other IE yet) the text in the box which slides down is not centerd. In firefox, when it slides down the corners are not smooth, but they are in IE. Live test here Code: <script type="text/javascript"> $(document).ready(function() { $('#nav_top').corners('5px'); $('#nav_bottom').hide(); $('#nav_bottom').corners(); $('#link').hover(function() { $('#nav_top').corners('10px top'); $('#nav_bottom').stop(true, true).slideDown(); $('#nav_bottom').slideDown("slow"); }, function () { $('#nav_bottom').slideUp("fast"); } ); }); </script> <div id="nav_top"> <a href="javascript:void(0);" id="link">Hover</a> <div id="nav_bottom"> <br />Stuff </div> </div> </div> Any advice, also is it better to use .hover or .mouseEnter / mouseLeave? Thanks

    - by Ed
    I am trying to figure out this fullcalendar and how to get events from database. I am using asp .net I am using a webservice that has something like this. I am just trying to put a test record first then I will tie it to the database once i get it working. Any help would be greatly appreciated! Thanks alot! Just trying to figure out how to tie my webservice. So my webservice goes like so. _ _ _ _ Public Class WebService1 Inherits System.Web.Services.WebService <WebMethod()> _ <ScriptMethod(ResponseFormat:=ResponseFormat.Json, UseHttpGet:=True)> _ Public Function Getcalendar() As String Dim sb As New StringBuilder Dim sw As New IO.StringWriter(sb) Dim strOut As String = String.Empty Using writer As New JsonTextWriter(sw) writer.WriteStartObject() writer.WritePropertyName("id") writer.WriteValue("999") writer.WritePropertyName("title") writer.WriteValue("my test") writer.WritePropertyName("allday") writer.WriteValue("false") writer.WritePropertyName("start") writer.WriteValue("2010-04-14T11:00:00") writer.WritePropertyName("end") writer.WriteValue("2010-04-14T13:00:00") writer.WriteEndObject() strOut = sw.ToString End Using Return strOut End Function End Class And my html goes like this <script type="text/javascript"> $(document).ready(function() { $('#calendar').fullCalendar({ header: { left: 'prev,next today', center: 'title', right: 'month,agendaWeek,agendaDay' }, editable: true, events: RVCSC.WebService1.Getcalendar() }); });

  • Testing Async downloads with ASIHTTPRequest

    - by Baishampayan Ghose
    I am writing a simple library using ASIHTTPRequest where I am fetching URLs in an async manner. My problem is that the main function that I have written to test my lib exits before the async calls are finished. I am very new to Obj C and iPhone development, can anyone suggest a good way to wait before all the requests are finished in the main function? Currently, my main function looks like this - int main(int argc, char *argv[]) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; IBGApp *ibgapp = [[IBGApp alloc] init]; IBGLib *ibgl = [[IBGLib alloc] initWithUsername:@"joe" andPassword:@"xxx"]; // The two method calls below download URLs async. [ibgl downloadURL:@"http://yahoo.com/" withRequestDelegate:ibgapp andRequestSelector:@selector(logData:)]; [ibgl downloadURL:@"http://google.com/" withRequestDelegate:ibgapp andRequestSelector:@selector(logData:)]; [pool release]; return 0; // I reach here before the async calls are done. } So what is the best way to wait till the async calls are done? I tried putting sleep, but obviously doesn't work.

  • IE problem: keyboard interaction with checkbox

    - by Bobby Eickhoff
    I have an HTML table, and each row has a checkbox for selecting or deselecting its row. Whenever a checkbox changes value, I need to add or remove highlighting to the row and also ensure that the page's submit button is only enabled when at least one row is selected and disabled otherwise. The checkbox event handler is defined by the following function: function getCheckboxCallback() { return function () { var parentRow = getParentRow(this); if (!parentRow) { return; // No parent row found; abort } // Adjust the appearance of the row setSelected(parentRow, this.checked); // Count the number of selected table rows, and disable the submit // button whenever no rows are selected enforceInvariants(); return true; }; } Elsewhere in the same module, the checkboxes are given the event handlers: checkbox.onchange = getCheckboxCallback(); checkbox.onclick = getCheckboxCallback(); // alleged IE fix I'm working in Windows XP, and everything works fine in both Firefox 3 and Opera 9. However, IE 7 does not handle keyboard interaction well (mouse interaction works fine). The problem is that if a checkbox has the focus and I hit the spacebar, the checkbox doesn't get checked -- instead it gets half checked (it has the same shadowed appearance that it would get immediately after a mousedown). I have to press the spacebar a second time to actually check the box. Similarly, it requires two key presses to uncheck it. Oddly enough, if I hold down the spacebar for a few moments, then a single press works as expected. Can anyone explain what is going on here? Is there something I'm doing wrong in the JavaScript code that is causing this behavior? How can I fix this?

  • Window message procedures in Linux vs Windows

    - by mizipzor
    In Windows when you create a window, you must define a (c++) LRESULT CALLBACK message_proc(HWND Handle, UINT Message, WPARAM WParam, LPARAM LParam); to handle all the messages sent from the OS to the window, like keypresses and such. Im looking to do some reading on how the same system works in Linux. Maybe it is because I fall a bit short on the terminology but I fail to find anything on this through google (although Im sure there must be plenty!). Is it still just one single C function that handles all the communication? Does the function definition differ on different WMs (Gnome, KDE) or is it handled on a lower level in the OS? Edit: Ive looked into tools like QT and WxWidgets, but those frameworks seems to be geared more towards developing GUI extensive applications. Im rather looking for a way to create a basic window (restrict resize, borders/decorations) for my OGL graphics and retrieve input on more than one platform. And according to my initial research, this kind of function is the only way to retrieve that input. What would be the best route? Reading up, learning and then use QT or WxWidgets? Or learning how the systems work and implement those few basic features I want myself?

  • searching for a programming platform with hot code swap

    - by Andreas
    I'm currently brainstorming over the idea how to upgrade a program while it is running. (Not while debugging, a "production" system.) But one thing that is required for it, is to actually submit the changed source code or compiled byte code into the running process. Pseudo Code var method = typeof(MyClass).GetMethod("Method1"); var content = //get it from a database (bytecode or source code) SELECT content FROM methods WHERE id=? AND version=? method.SetContent(content); At first, I want to achieve the system to work without the complexity of object-orientation. That leads to the following requirements: change source code or byte code of function drop functions add new functions change the signature of a function With .NET (and others) I could inject a class via an IoC and could thus change the source code. But the loading would be cumbersome, because everything has to be in an Assembly or created via Emit. Maybe with Java this would be easier? The whole ClassLoader is replacable, I think. With JavaScript I could achieve many of the goals. Simply eval a new function (MyMethod_V25) and assign it to MyClass.prototype.MyMethod. I think one can also drop functions somehow with "del" Which general-purpose platform can handle such things?

  • Controlling the scope of a document.write call coming from a third party

    - by pingrey
    Dear all, I'm writing a webpage that relies on an external javascript file (that I have no control of), which returns data by using document.write's. Is there any way to dynamically call the function without it overwriting the whole document? The most concise code I can think of is below: <html> <head> <script type="text/javascript"> function horriblefunction () { document.write("new text"); } </script> </head> <body> Starting Text... <div id="pleasewriteinme"></div> Other text... <button onclick="horriblefunction();">Click</button> </body> </html> The idea beginning that without altering "horriblefunction()" (as it's external) the new text could be placed in the div instead of overwriting the page. Is this possible or does the function have to be called inside the div as the page is created? Thanks for you help

  • F# exercise help - Beginner

    - by bobjink
    I hope you can help me with these exercises I have been stuck with. I am not in particular looking for the answers. Tips that help me solve them myself are just as good :) 1. Write a function implode : char list - string so that implode s returns the characters concatenated into a string: let implode (cArray:char list) = List.foldBack (+) 0 cArray;; Error. I am thinking that i need to cast every char to strings before I do the above. I bet however, that there is a much simpler and better solution. 2. Write a function palindrome : string - bool, so that palindrome s returns true if the string s is a palindrome let isIdentical cArray1 cArray2 = (cArray1 = cArray2);; let palinDrome (word:string) = isIdentical(word.ToCharArray(), Array.rev(word.ToCharArray()));; I get the value: val palinDrome : string - (char [] * char [] - bool), which is not what I want. 3. Write a function combinePair : int list - int list so that combinePair xs returns the list with elements from xs combined into pairs. If xs contains an odd number of elements, then the last element is thrown away: I have no idea for this one.

  • I like the way they Design/Architecture it but how do I implement this

    - by Rachel
    Summary: I have different components on homepage and each components shows some promotion to the user. I have Cart as one Component and depending upon content of the cart promotion are show. I have to track user online activities and send that information to Omniture for Report Generation. Now my components are loaded asynchronously basically are loaded when AjaxRequest is fired up and so there is not fix pattern or rather information on when components will appear on the webpages. Now in order to pass information to Omniture I need to call track function on $(document).(ready) and append information for each components(7 parameters are required by Omniture for each component). So in the init:config function of each component am calling Omniture and passing paramters but now no. of Omniture calls is directly proportional to no. of Components on the webpage but this is not acceptable as each call to Omniture is very expensive. Now I am looking for a way where in I can club the information about 7 parameters and than make one Call to Omniture wherein I pass those information. Points to note is that I do not know when the components are loaded and so there is no pre-defined time or no. of components that would be loaded. The thing is am calling track function when document is ready but components are loaded after call to Omniture has been made and so my question is Q: How can I collect the information for all the components and than just make one call to Omniture to send those information ? As mentioned, I do not know when the components are loaded as they are done on the Ajax Request. Hope I am able to explain my challenge and would appreciate if some one can provide from Design/Architect Solutions for the Challenge.

  • Getting value of "i" from GEvent

    - by Cosizzle
    Hello, I'm trying to add an event listener to each icon on the map when it's pressed. I'm storing the information in the database and the value that I'm wanting to retrive is "i" however when I output "i", I get it's last value which is 5 (there are 6 objects being drawn onto the map) Below is the code, what would be the best way to get the value of i, and not the object itself. var drawLotLoc = function(id) { var lotLoc = new GIcon(G_DEFAULT_ICON); // create icon object lotLoc.image = url+"images/markers/lotLocation.gif"; // set the icon image lotLoc.shadow = ""; // no shadow lotLoc.iconSize = new GSize(24, 24); // set the size var markerOptions = { icon: lotLoc }; $.post(opts.postScript, {action: 'drawlotLoc', id: id}, function(data) { var markers = new Array(); // lotLoc[x].description // lotLoc[x].lat // lotLoc[x].lng // lotLoc[x].nighbourhood // lotLoc[x].lot var lotLoc = $.evalJSON(data); for(var i=0; i<lotLoc.length; i++) { var spLat = parseFloat(lotLoc[i].lat); var spLng = parseFloat(lotLoc[i].lng); var latlng = new GLatLng(spLat, spLng) markers[i] = new GMarker(latlng, markerOptions); myMap.addOverlay(markers[i]); GEvent.addListener(markers[i], "click", function() { console.log(i); // returning 5 in all cases. // I _need_ this to be unique to the object being clicked. console.log(this); }); } });

  • SFINAE failing with enum template parameter

    - by zeroes00
    Can someone explain the following behaviour (I'm using Visual Studio 2010). header: #pragma once #include <boost\utility\enable_if.hpp> using boost::enable_if_c; enum WeekDay {MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY, SUNDAY}; template<WeekDay DAY> typename enable_if_c< DAY==SUNDAY, bool >::type goToWork() {return false;} template<WeekDay DAY> typename enable_if_c< DAY!=SUNDAY, bool >::type goToWork() {return true;} source: bool b = goToWork<MONDAY>(); compiler this gives error C2770: invalid explicit template argument(s) for 'enable_if_c<DAY!=6,bool>::type goToWork(void)' and error C2770: invalid explicit template argument(s) for 'enable_if_c<DAY==6,bool>::type goToWork(void)' But if I change the function template parameter from the enum type WeekDay to int, it compiles fine: template<int DAY> typename enable_if_c< DAY==SUNDAY, bool >::type goToWork() {return false;} template<int DAY> typename enable_if_c< DAY!=SUNDAY, bool >::type goToWork() {return true;} Also the normal function template specialization works fine, no surprises there: template<WeekDay DAY> bool goToWork() {return true;} template<> bool goToWork<SUNDAY>() {return false;} To make things even weirder, if I change the source file to use any other WeekDay than MONDAY or TUESDAY, i.e. bool b = goToWork<THURSDAY>(); the error changes to this: error C2440: 'specialization' : cannot convert from 'int' to 'const WeekDay' Conversion to enumeration type requires an explicit cast (static_cast, C-style cast or function-style cast)

  • Azure SDK causes Node.js service bus call to run slow

    - by PazoozaTest Pazman
    I am using this piece of code to call the service bus queue from my node.js server running locally using web matrix, I have also upload to windows azure "web sites" and it still performs slowly. var sb1 = azure.createServiceBusService(config.serviceBusNamespace, config.serviceBusAccessKey); sbMessage = { "Entity": { "SerialNumbersToCreate": '0', "SerialNumberSize": config.usageRates[3], "BlobName": 'snvideos' + channel.ChannelTableName, "TableName": 'snvideos' + channel.ChannelTableName } }; sb1.getQueue('serialnumbers', function(error, queue){ if (error === null){ sb1.sendQueueMessage('serialnumbers', JSON.stringify(sbMessage), function(error) { if (!error) res.send(req.query.callback + '({data: ' + JSON.stringify({ success: true, video: newVideo }) + '});'); else res.send(req.query.callback + '({data: ' + JSON.stringify({ success: false }) + '});'); }); } else res.send(req.query.callback + '({data: ' + JSON.stringify({ success: false }) + '});'); }); It can be up to 5 seconds before the server responds back to the client with the return result. When I comment out the sb1.getQueue('serialnumbers', function(error, queue){ and just have it return without sending a queue message it performs in less than 1 second. Why is that? Is my approach to using the azure sdk service bus correct? Any help would be appreciated.

  • jQuery working in everything but IE7. (checked my commas)

    - by deadlyhifi
    The following code works in IE8, FF, Safari, Chrome etc. (not bothering with IE6 for this one), but doesn't work in IE7. I've been through the code with a fine tooth-comb. Checked the commas, messed around with ; but it's not going anywhere. I'm using the jQuery Validate and Uploadify scripts. Can anyone see the problem here? Thanks. <script type="text/javascript"> jQuery(document).ready(function($) { $("#validateform").validate({ errorClass: 'invalid', rules: { bike_url: { required: true, url: true } } }) $("#uploadify").uploadify({ 'uploader' : '<?php echo $url .

  • Converted some PHP functions to c# but getting different results

    - by Tom Beech
    With a bit of help from people on here, i've converted the following PHP functions to C# - But I get very different results between the two and can't work out where i've gone wrong: PHP: function randomKey($amount) { $keyset = "abcdefghijklmABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"; $randkey = ""; for ($i=0; $i<$amount; $i++) $randkey .= substr($keyset, rand(0, strlen($keyset)-1), 1); return $randkey; } public static function hashPassword($password) { $salt = self::randomKey(self::SALTLEN); $site = new Sites(); $s = $site->get(); return self::hashSHA1($s->siteseed.$password.$salt.$s->siteseed).$salt; } c# public static string randomKey(int amount) { string keyset = "abcdefghijklmABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"; string randkey = string.Empty; Random random = new Random(); for (int i = 0; i < amount; i++) { randkey += keyset.Substring(0, random.Next(2, keyset.Length - 2)); } return randkey; } static string hashPassword(string password) { string salt = randomKey(4); string siteSeed = "6facef08253c4e3a709e17d9ff4ba197"; return CalculateSHA1(siteSeed + password + salt + siteSeed) + siteSeed; } static string CalculateSHA1(string ipString) { SHA1 sha1 = new SHA1CryptoServiceProvider(); byte[] ipBytes = Encoding.Default.GetBytes(ipString.ToCharArray()); byte[] opBytes = sha1.ComputeHash(ipBytes); StringBuilder stringBuilder = new StringBuilder(40); for (int i = 0; i < opBytes.Length; i++) { stringBuilder.Append(opBytes[i].ToString("x2")); } return stringBuilder.ToString(); } EDIT The string 'password' in the PHP function comes out as "d899d91adf31e0b37e7b99c5d2316ed3f6a999443OZl" in the c# it comes out as: "905d25819d950cf73f629fc346c485c819a3094a6facef08253c4e3a709e17d9ff4ba197"

  • Flash "visible" issue

    - by justkevin
    I'm writing a tool in Flex that lets me design composite sprites using layered bitmaps and then "bake" them into a low overhead single bitmapData. I've discovered a strange behavior I can't explain: toggling the "visible" property of my layers works twice for each layer (i.e., I can turn it off, then on again) and then never again for that layer-- the layer stays visible from that point on. If I override "set visible" on the layer as such: override public function set visible(value:Boolean):void { if(value == false) this.alpha = 0; else {this.alpha = 1;} } The problem goes away and I can toggle "visibility" as much as I want. Any ideas what might be causing this? Edit: Here is the code that makes the call: private function onVisibleChange():void { _layer.visible = layerVisible.selected; changed(); } The changed() method "bakes" the bitmap: public function getBaked():BitmapData { var w:int = _composite.width + (_atmosphereOuterBlur * 2); var h:int = _composite.height + (_atmosphereOuterBlur * 2); var bmpData:BitmapData = new BitmapData(w,h,true,0x00000000); var matrix:Matrix = new Matrix(); var bounds:Rectangle = this.getBounds(this); matrix.translate(w/2,h/2); bmpData.draw(this,matrix,null,null,new Rectangle(0,0,w,h),true); return bmpData; } Incidentally, while the layer is still visible, using the Flex debugger I can verify that the layer's visible value is "false".

  • Save a form in an XML file using Ajax and JSP

    - by novellino
    Hello, I want to create a simple form with a name and an email and save these data in an XML file. So far I found that using Ajax with jQuery is quite easy. So I used the usual code: //dataString have the values taken from the form var dataString = 'name='+ name + '&email=' + email; $.ajax({ type: "POST", url: "users.xml", data: dataString, dataType: "xml", success: function() { .... } }); If I understood well, in the url I should add the name of the XML file that will be created. When the user clicks a button I call the function with the Ajax request, and then I should call somewhere a function for generating the xml. I am using also two beans. One is for setting the elements of the user and the other is for saving the data in the XML. I am using the XStream library for the xml although I don't know if is the best solution. The problem now it that I can not connect all these together in order to save the data in the XML. Does anyone know what should I do? Thanks a lot!

  • Reverse ordered list for jquery submitted comments

    - by g-man
    Hey guys I have one more question lol. I am using a script that allows users to submit comments through jquery ajax, however when they are submitted, the submitted comments submit at the bottom of the other comments which are sorted in descending order (newest on top) when the page first loads (due to mysql query). Is there a way to make it submit on top through some sort of sorting javascript function? function prepare(response) { var d = new Date(); count++; d.setTime(response.time*1000); var mytime = d.getHours()+':'+d.getMinutes()+':'+d.getSeconds(); var string = '<li class="shoutbox-list" id="list-'+count+'">' + '<span class="date">'+mytime+'</span>' + '<span class="shoutbox-list-nick"><a href="statistics.php?user='+response.user+'">'+response.user+'</a>:</span>' + '<span class="msg">'+response.message+'</span>' +'</li>'; return string; } function success(response, status) { if(status == 'success') { lastTime = response.time; $('#daddy-shoutbox-list').append(prepare(response)); $('input[name=message]').attr('value', '').focus(); $('#list-'+count).fadeIn('slow'); timeoutID = setTimeout(refresh, 3000); } } <div id="daddy-shoutbox"> <ol id="daddy-shoutbox-list"></ol> </div>

  • Define a swig interface file for generation of wrapper to every type from some header file

    - by Dmitriy Matveev
    Hi! We're using some C library in our Java project. Several years ago some other developer which has retired few years ago (as always) has created all the wrappers for us. The wrappers were generated by the swig, but the interface file is lost now. The basic idea of library and the wrappers for it is following: There only one function which returns pointer to some complex object. And there are wrapper for that function. The complex object is a tree-like structure with dozens of node kinds and types (C structures) used to represent them. There are hundreds of wrappers for every field of every type and we're trying to use them all. The library was updated some time ago and now there are some new data we unaware of which yet, but would like to use. This data is contained in some of the objects indirectly contained or referenced from the object created by the function we call (Some new fields and types were added). I know that I shouldn't make any changes to the wrappers by hand and should rather modify the interface, but as I already wrote it's missing. For now I only want to generate wrappers some few types which are added/changed and them to our old wrappers, but later I want to start creation of interface file which will define "what and how should be wrapped". All the definitions necessary for us are defined in single header file. Is it possible to tell swig to generate wrappers for every type in this header? If so, how can I write such interface file?

  • Python subprocess Popen.communicate() equivalent to Popen.stdout.read()?

    - by Christophe
    Very specific question (I hope): What are the differences between the following three codes? (I expect it to be only that the first does not wait for the child process to be finished, while the second and third ones do. But I need to be sure this is the only difference...) I also welcome other remarks/suggestions (though I'm already well aware of the shell=True dangers and cross-platform limitations) Note that I already read Python subprocess interaction, why does my process work with Popen.communicate, but not Popen.stdout.read()? and that I do not want/need to interact with the program after. Also note that I already read Alternatives to Python Popen.communicate() memory limitations? but that I didn't really get it... First code: from subprocess import Popen, PIPE def exe_f(command='ls -l', shell=True): "Function to execute a command and return stuff" process = Popen(command, shell=shell, stdout=PIPE, stderr=PIPE) stdout = process.stdout.read() stderr = process.stderr.read() return process, stderr, stdout Second code: from subprocess import Popen, PIPE from subprocess import communicate def exe_f(command='ls -l', shell=True): "Function to execute a command and return stuff" process = Popen(command, shell=shell, stdout=PIPE, stderr=PIPE) (stdout, stderr) = process.communicate() return process, stderr, stdout Third code: from subprocess import Popen, PIPE from subprocess import wait def exe_f(command='ls -l', shell=True): "Function to execute a command and return stuff" process = Popen(command, shell=shell, stdout=PIPE, stderr=PIPE) code = process.wait() stdout = process.stdout.read() stderr = process.stderr.read() return process, stderr, stdout Thanks.

    I am trying to create a csv file of some data. I have wrote a function that successfully does this.... Private Sub CreateCSVFile(ByVal dt As DataTable, ByVal strFilePath As String) Dim sw As New StreamWriter(strFilePath, False) ''# First we will write the headers. ''EDataTable dt = m_dsProducts.Tables[0]; Dim iColCount As Integer = dt.Columns.Count For i As Integer = 0 To iColCount - 1 sw.Write(dt.Columns(i)) If i < iColCount - 1 Then sw.Write(",") End If Next sw.Write(sw.NewLine) ''# Now write all the rows. For Each dr As DataRow In dt.Rows For i As Integer = 0 To iColCount - 1 If Not Convert.IsDBNull(dr(i)) Then sw.Write(dr(i).ToString()) End If If i < iColCount - 1 Then sw.Write(",") End If Next sw.Write(sw.NewLine) Next sw.Close() End Sub The problem is I am not using the streamwriter object correctly for what I trying to accomplish. Since this is an asp.net I need the user to pick a local filepath to put the file on. If I pass any path to this function its gonna try to write it to the directory specified on the server where the code is. I would like this to popup and let the user select a place on their local machine to put the file.... Dim exData As Byte() = File.ReadAllBytes(Server.MapPath(eio)) File.Delete(Server.MapPath(eio)) Response.AddHeader("content-disposition", String.Format("attachment; filename={0}", fn)) Response.ContentType = "application/x-msexcel" Response.BinaryWrite(exData) Response.Flush() Response.End() I am calling the first function in code like this... Dim emplTable As DataTable = SiteAccess.DownloadEmployee_H() CreateCSVFile(emplTable, "C:\\EmplTable.csv") Where I dont want to have specify the file loaction (because this will put the file on the server and not on a client machine) but rather let the user select the location on their client machine. Can someone help me put this together? Thanks in advance.

  • Jquery autocomplete webservices - what am i doing wrong??

    - by dzajdol
    I created a class for JSON responses: public class PostCodeJson { public String Text { get; private set; } public String Value { get; private set; } #region Constructors /// <summary> /// Empty constructor /// </summary> public PostCodeJson() { this.Text = String.Empty; this.Value = String.Empty; } /// <summary> /// Constructor /// </summary> /// <param name="_text"></param> /// <param name="_value"></param> public PostCodeJson(String _text, String _value) { this.Text = _text; this.Value = _value; } #endregion Constructors } and function returns list of this class using in webservices method: [WebMethod] public List<PostCodeJson> GetPostCodesCompletionListJson(String prefixText, Int32 count) { return LibDataAccess.DBServices.PostCodes.GetPostCodeJson(prefixText, count); } And in aspx i do this that: <script> $(document).ready(function() { $("#<%=pc.ClientID %>").autocomplete( baseUrl + "WebServices/Autocomplete.asmx/GetPostCodesCompletionListJson", { parse: function(data) { var array = new Array(); for (var i = 0; i < data.length; i++) { var datum = data[i]; var name = datum.Text; var display = name; array[array.length] = { data: datum, value: display, result: datum.Value }; } return array; }, dataType: "xml" }); }); </script> and when you enter something in the box i got an error: Request format is unrecognized for URL unexpectedly ending in '/GetPostCodesCompletionListJson What am I doing wrong??

  • Customize jQuery.aptags plugin - mouseclick submit from dropdown list

    - by atmorell
    Hello, I am using jquery.autocomplete.js and jquery.apitags to select a few elements from a dropdown list. This works great, and I can select multiple elements etc. However the jquery-aptags plugin does only fire when enter is pressed. This might confuse some users if they use the mouse to click instead of the arrows/enter on the keyboard. I think this is the code inside jquery.aptags that submits the tag. // // Hook to the keypress event. // $(this).bind('keypress', { __c: __c }, function (e) { var c = ''; var i = 0; var v = $(this).val(); if (e.keyCode == 13) { e.stopPropagation(); e.preventDefault(); __createSpans(this, v, e.data.__c, true); } }); I am wondering if it is possible to call the method directly from a new event. $('.ac_results > ul > li').livequery(function() { $(this).bind('click', function() { $('#address_city').aptags({__createSpans}); }); }); Any thoughts?

  • Flash CS4 compiler Error 1120 when embedding pngs into class instance variables.

    - by theolagendijk
    I have a Flash CS4 (Flash 9 ActionScript 3.0) project that compiles and runs perfectly on my machine. However it is part of a big batch of fla's that I want to compile on another (faster) machine. When I copy the project (the fla and all actionscripts and assets files) to the faster machine, it's Flash CS4 compiler gives me compiler error 1120 "Access of undefined property ButtonPause_PauseNormal". The property "PauseNormal" is an embedded png. The PNG is available. No transcoder errors. Here's the ActionScript for class "ButtonPause"; package nl.platipus.NissanESM.buttons { import flash.display.*; import flash.events.*; public class ButtonPause extends Sprite { [Embed(source="../../../../player/pause.png")] private var PauseNormal:Class; [Embed(source="../../../../player/pause_mo.png")] private var PauseMouseOver:Class; private var stateNormal:Bitmap; private var stateMouseOver:Bitmap; public function ButtonPause() { stateNormal = new PauseNormal(); stateNormal.width = 29; stateNormal.height = 14; stateNormal.alpha = 1; addChild(stateNormal); stateMouseOver = new PauseMouseOver(); stateMouseOver.width = 29; stateMouseOver.height = 14; stateMouseOver.alpha = 0; addChild(stateMouseOver); width = 29; height = 14; addEventListener(MouseEvent.MOUSE_OVER, handleMouseOver); addEventListener(MouseEvent.MOUSE_OUT, handleMouseOut ); } private function handleMouseOver(evt:MouseEvent):void { stateNormal.alpha = 0; stateMouseOver.alpha = 1; } private function handleMouseOut(evt:MouseEvent):void { stateNormal.alpha = 1; stateMouseOver.alpha = 0; } } } (Both machines run the exact same Flash CS4 Profesional Version 10.0.2 installation and both have the exact same publish settings and ActionScript 3.0 settings.) What's going on?
