  • jquery datatables add checkbox with ajax server side response

    - by dotneter
    I am using C# ASP .NET MVC and ajax calls. I am able to get the display of the table along with all features. But, I don't understand how do I add a checkbox and button. I have tried dom-checkbox as well but can't get it to work. Any help is appreciated. My code looks like this: $(document).ready(function () { $('#personTable').dataTable({ "bJQueryUI": true, "sPaginationType": "full_numbers", "bProcessing": true, "bServerSide": true, "sAjaxSource": "/Home/GetCustomData", "aoColumns": [ { "sSortDataType": "dom-checkbox", "sTitle": "Select", sName": "" }, { "sName": "ID", "sTitle": "ID" }, { "sName": "FirstName", "sTitle": "First Name" }, { "sName": "Email", "sTitle": "Email"}] }); }); My Html is : [table border="1" id="personTable" class="display"] [/table]

  • jQuery UI sortable('cancel') - this.helper is null

    - by Kerry
    I am trying to disable a sortable element from sorting when it has been double clicked. When I try to disable it, even without a condition, it gives me the error 'this.helper is null'. $('.roundedBox:first', division).sortable({ start: function( event, ui ) { if( true === true ) { $(this).sortable('cancel'); } $(this).parent().data( 'sorting', true ); }, stop: function() { $(this).parent().data( 'sorting', false ); }, items: '.department', update: function() {}, placeholder: 'department-placeholder' }) Any ideas on how I can do this? I don't need it to be this method. Literally anything thing that stops it will work. The problem is, sorting starts on a single click, but I have another action bound to double click. If it's double clicked, I don't want it to drag.

  • flash blocking javascript events

    - by jedierikb
    this is an edit of the original post now that I better understand the problem. now with source code! In IE, if body (or another html div has focus), then you keypress & click on flash at the same time, then release... a keyup event is never fired. It is not fired in javascript or in flash. Where is this keyup event? This is the order of event firing you get instead: javascriptKeyEvent:bodyDn ** currentFocuedElement: body javascriptKeyEvent:docDn ** currentFocuedElement: body actionScriptEvent::activate ** currentFocuedElement: [object] actionScriptEvent::mouseDown ** currentFocuedElement: [object] actionScriptEvent::mouseUp ** currentFocuedElement: [object] Subsequent keyup and keydown events are captured by flash, but that initial keyUp is never fired.. anywhere. And I need that keyup! Here is the html/javascript: <html> <head> <script type="text/javascript" src="p.js"></script> <script type="text/javascript" src="swfobject.js"></script> <script> function ic( evt ) { Event.observe( $("f1"), 'keyup', onKeyHandler.bindAsEventListener( this, "f1Up" ) ); Event.observe( $("f2"), 'keyup', onKeyHandler.bindAsEventListener( this, "f2Up" ) ); Event.observe( document, 'keyup', onKeyHandler.bindAsEventListener( this, "docUp" ) ); Event.observe( $("body"), 'keyup', onKeyHandler.bindAsEventListener( this, "bodyUp" ) ); Event.observe( window, 'keyup', onKeyHandler.bindAsEventListener( this, "windowUp" ) ); Event.observe( $("f1"), 'keydown', onKeyHandler.bindAsEventListener( this, "f1Dn" ) ); Event.observe( $("f2"), 'keydown', onKeyHandler.bindAsEventListener( this, "f2Dn" ) ); Event.observe( document, 'keydown', onKeyHandler.bindAsEventListener( this, "docDn" ) ); Event.observe( $("body"), 'keydown', onKeyHandler.bindAsEventListener( this, "bodyDn" ) ); Event.observe( window, 'keydown', onKeyHandler.bindAsEventListener( this, "windowDn" ) ); Event.observe( "clr", "mousedown", clearHandler.bindAsEventListener( this ) ); swfobject.embedSWF( "tmp.swf", "f2", "100%", "20px", "9.0.0.0", null, {}, {}, {} ); } function clearHandler( evt ) { clear( ); } function clear( ) { $("log").innerHTML = ""; } function onKeyHandler( evt, dn ) { logIt( "javascriptKeyEvent:"+dn ); } function AS2JS( wha ) { logIt( "actionScriptEvent::" + wha ); } function logIt( k ) { var id = document.activeElement; if (id.identify) { id = id.identify(); } $("log").innerHTML = k + " ** focuedElement: " + id + "<br>" + $("log").innerHTML; } Event.observe( window, 'load', ic.bindAsEventListener(this) ); </script> </head> <body id="body"> <div id="f1"><div id="f2" style="width:100%;height:20px; position:absolute; bottom:0px;"></div></div> <div id="clr" style="color:blue;">clear</div> <div id="log" style="overflow:auto;height:200px;width:500px;"></div> </body> </html> Here is the as3 code: package { import flash.display.Sprite; import flash.display.StageAlign; import flash.display.StageScaleMode; import flash.events.KeyboardEvent; import flash.events.MouseEvent; import flash.events.Event; import flash.external.ExternalInterface; public class tmpa extends Sprite { public function tmpa( ):void { extInt("flashInit"); stage.align = StageAlign.TOP_LEFT; stage.scaleMode = StageScaleMode.NO_SCALE; stage.addEventListener( KeyboardEvent.KEY_DOWN, keyDnCb, false, 0, true ); stage.addEventListener( KeyboardEvent.KEY_UP, keyUpCb, false, 0, true ); stage.addEventListener( MouseEvent.MOUSE_DOWN, mDownCb, false, 0, true ); stage.addEventListener( MouseEvent.MOUSE_UP, mUpCb, false, 0, true ); addEventListener( Event.ACTIVATE, activateCb, false, 0, true ); addEventListener( Event.DEACTIVATE, dectivateCb, false, 0, true ); } private function activateCb( evt:Event ):void { extInt("activate"); } private function dectivateCb( evt:Event ):void { extInt("deactivate"); } private function mDownCb( evt:MouseEvent ):void { extInt("mouseDown"); } private function mUpCb( evt:MouseEvent ):void { extInt("mouseUp"); } private function keyDnCb( evt:KeyboardEvent ):void { extInt( "keyDn" ); } private function keyUpCb( evt:KeyboardEvent ):void { extInt( "keyUp" ); } private function extInt( wha:String ):void { try { ExternalInterface.call( "AS2JS", wha ); } catch (ex:Error) { trace('ex: ' + ex); } } } }

  • Richfaces calendar manual input value not binding

    - by John
    Hi, I've got a richfaces calendar component defined as <rich:calendar id="startDate" value="#{myBean.dateSet.startDate}" timeZone="#{myBean.dateSet.timeZone}" datePattern="#{myBean.dateSet.datePattern}" enableManualInput="true" immediate="true"> <a4j:support event="onchanged" action="#{myBean.adjustEndDate}" reRender="startDate,endDate" ajaxSingle="true" /> </rich:calendar> when I'm changing the date using the calendar popup/gui everything is working fine. However when I'm changing it via the input text field, the value is not being updated to myBean.dateSet.startDate, although it is being updated correctly on the calendar component itself (i.e. if I click the icon for calendar popup it shows the updated current date). Any suggestions on how I can get it to update the value to myBean correctly? Thanks!

  • How do I setup ASP.NET MVC 2 with MySQL?

    - by NovaJoe
    Okay, so I'm cheating and not actually a question, but instead making a flat-out post. I know that goes against the grain of Stack Overflow, but this is too valuable not to share. I'm assuming that you have Visual Studio Professional 2008 and access to an instance of MySQL server. This MAY work with VS2008 Web edition, but not at all sure. If you haven't, install MySQL Connector for .NET (6.2.2.0 at the time of this write-up) Optional: install MySQL GUI Tools If you haven't, install MVC 2 RTM, or better yet, use Microsoft's Web Platform Installer. Create an empty MySQL database. If you don't want to access your application with the MySQL root user account (insecure), create a user account and assign the appropriate privileges (outside the scope of this write-up). Create a new MVC 2 application in Visual Studio In the MVC 2 app, reference MySql.Web.dll. It will either be in your GAC, or in the folder that the MySQL Connector installer put it. Modify the connection strings portion of your web.config: <connectionStrings> <remove name="LocalMySqlServer"/> <add name="MySqlMembershipConnection" connectionString="Data Source=[MySql server host name];user id=[user];password=[password];database=[database name];" providerName="MySql.Data.MySqlClient"/> </connectionStrings> Modify the membership portion of your web.config: <membership defaultProvider="MySqlMembershipProvider"> <providers> <clear/> <add name="MySqlMembershipProvider" type="MySql.Web.Security.MySQLMembershipProvider, MySql.Web, Version=6.2.2.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" connectionStringName="MySqlMembershipConnection" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="true" passwordFormat="Hashed" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="/" autogenerateschema="true"/> </providers> </membership> Modify the role manager portion of your web.config: <roleManager enabled="true" defaultProvider="MySqlRoleProvider"> <providers> <clear /> <add connectionStringName="MySqlMembershipConnection" applicationName="/" name="MySqlRoleProvider" type="MySql.Web.Security.MySQLRoleProvider, MySql.Web, Version=6.2.2.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" autogenerateschema="true"/> </providers> </roleManager> Modify the profile portion of your web.config: <profile> <providers> <clear/> <add type="MySql.Web.Security.MySQLProfileProvider, MySql.Web, Version=6.2.2.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" name="MySqlProfileProvider" applicationName="/" connectionStringName="MySqlMembershipConnection" autogenerateschema="true"/> </providers> </profile> At this point, you ought to be able to run the app and have the default ASP.NET MVC 2 home page come up in your browser. However, it may be a better idea to first run the ASP.NET Web configuration Tool (in Visual Studio top menus: Project - ASP.NET Configuration). Once the tool launches, check out each of the tabs; no errors = all good. The configuration tool Nathan Bridgewater's blog was essential to getting this working. Kudos, Nathan. Look for the "Configuration Tool" heading half way down the page. The public key token on the MySql.web.dll that I've posted here ought not change any time soon. But in case you suspect a bad token string from copying and pasting or whatever, just use the Visual Studio command line to run: "sn -T [Path\to\your.dll]" in order to get the correct public key token. There you have it, ASP.NET MVC 2 running over MySQL. Cheers!

  • SelectedIndexChanged for programmatically created dropdownlist in ASP.NET fires multiple times.

    - by Achilles
    Consider the following: dim dropdownlist1 as new dropdownlist dim dropdownlist2 as new dropdownlist dim dropdownlist3 as new dropdownlist dropdownlist1.AutoPostBack = true dropdownlist2.AutoPostBack = true dropdownlist3.AutoPostBack = true AddHandler dropdownlist1.SelectedIndexChanged, AddressOf SomeEvent AddHandler dropdownlist2.SelectedIndexChanged, AddressOf SomeEvent AddHandler dropdownlist3.SelectedIndexChanged, AddressOf SomeEvent The SomeEvent fires as expected when any of the dropdown's selection is changed. However if say DropdownList2 has a selection made then I make a selection with either DropDownList1 or DropdownList3, then SomeEvent fires again. What is causing this behavior and how do I get just a single raising of that event? I suspect that when the viewstate for the dynamcially created dropdownlists is restored and the selection restored, then the event is fired because technically the selected index did change when the control was recreated. The reason I suspect this is that the event fires the for each dropdownlist...

I tried to over-ride the BaseInlineFormset class with a new queryset, but couldnt figure out how to correctly pass the experiment parameter.

  • Basic Boost Regex question

    - by shuttle87
    I'm trying to write some c++ code that tests if a string is in a particular format. In this program there is a height followed by some decimal numbers: for example "height 123.45" or "height 12" would return true but "SomeOtherString 123.45" would return false. My first attempt at this was to write the following: string action; cin >> action; boost::regex EXPR( "^height \\d*(\\.\\d{1,2})?$/" ) ;//height format regex bool height_format_matches = boost::regex_match( action, EXPR ) ; if(height_format_matches==true){ \\do some stuff } However height_format_matches never seemed to be true. Any help is greatly appreciated!

  • Facebook Like button working but not sharing

    - by Victor P
    Im using the XFBML version of the Like button but the "Share it" box with the space to leave a comment doesn't show up after clicking "Recommend". The rest works fine. Im using this code: <fb:like href="www.google.cl" width="300" action="recommend" font="lucida grande"></fb:like> And, in the end of the page </body> <div id="fb-root"></div> <script src="http://connect.facebook.net/en_US/all.js"></script> <script> FB.init({appId: '1234567890', status: true, cookie: true, xfbml: true}); FB.Event.subscribe('auth.sessionChange', function(response) { if (response.session) { // A user has logged in, and a new cookie has been saved } else { // The user has logged out, and the cookie has been cleared } }); </script> </html> Do you know what is happening? Any advice is warmly received. Thanks

  • Objects with permissions assigned by django-guardian not visible in admin

    - by jul
    I'm using django-guardian in order to manage per object permission. For a given user I give permission all permission on one object: joe = User.objects.get(username="joe") mytask = Task.objects.get(pk=1) assign('add_task', joe, mytask) assign('change_task', joe, mytask) assign('delete_task', joe, mytask) and I get, as expected: In [57]: joe.has_perm("add_task", mytask) Out[57]: True In [58]: joe.has_perm("change_task", mytask) Out[58]: True In [59]: joe.has_perm("delete_task", mytask) Out[59]: True In admin.py I also make TaskAdmin inherit from GuardedModelAdmin instead of admin.ModelAdmin Now when I connect to my site with joe, on the admin I get: You don't have permission to edit anything Am I not supposed to be able to edit the object mytask? Do I have to set some permissions using the built-in model-based permission system? Am I missing anything? Thank you

  • Get Members of Band

    - by user168083
    If I look at the Freebase page for the band '311', I see Chad Sexton listed. http://www.freebase.com/view/en/311 I am trying to query for the members of a band : { "name" : "311", "/music/artist/album" : [{"name":null, "id":null, "optional": true}], "type|=" : ["/music/artist","/music/musical_group"], "/award/award_winner/awards_won" : ["award":null, "optional" => true], "/award/award_nominated_work/award_nominations" : ["award":null, "optional" => true], "/music/artist/supporting_artists":[{}] } I thought supporting_artists would return the band member names, but the array is always empty. But if I query for all properties related to Chad Sexton, I don't see 311 mentioned. But he is listed as member on the Freebase web info page (which is correct). { "*": null, "name": "Chad Sexton", "type": "/music/artist" } How can I grab the band member names along with the band info?

  • Prime Numbers Code Help

    - by andrew
    Hello Everybody, I am suppose to "write a Java program that reads a positive integer n from standard input, then prints out the first n prime number." It's divided into 3 parts. 1st: This function will return true or false according to whether m is prime or composite. The array argument P will contain a sufficient number of primes to do the testing. Specifically, at the time isPrime() is called, array P must contain (at least) all primes p in the range 2 p m . For instance, to test m = 53 for primality, one must do successive trial divisions by 2, 3, 5, and 7. We go no further since 11 53 . Thus a precondition for the function call isPrime(53, P) is that P[0] = 2 , P[1] = 3 , P[2] = 5, and P[3] = 7 . The return value in this case would be true since all these divisions fail. Similarly to test m =143 , one must do trial divisions by 2, 3, 5, 7, and 11 (since 13 143 ). The precondition for the function call isPrime(143, P) is therefore P[0] = 2 , P[1] = 3 , P[2] = 5, P[3] = 7 , and P[4] =11. The return value in this case would be false since 11 divides 143. Function isPrime() should contain a loop that steps through array P, doing trial divisions. This loop should terminate when 2 either a trial division succeeds, in which case false is returned, or until the next prime in P is greater than m , in which case true is returned. Then there is the "main function" • Check that the user supplied exactly one command line argument which can be interpreted as a positive integer n. If the command line argument is not a single positive integer, your program will print a usage message as specified in the examples below, then exit. • Allocate array Primes[] of length n and initialize Primes[0] = 2 . • Enter a loop which will discover subsequent primes and store them as Primes[1] , Primes[2], Primes[3] , ……, Primes[n -1] . This loop should contain an inner loop which walks through successive integers and tests them for primality by calling function isPrime() with appropriate arguments. • Print the contents of array Primes[] to stdout, 10 to a line separated by single spaces. In other words Primes[0] through Primes[9] will go on line 1, Primes[10] though Primes[19] will go on line 2, and so on. Note that if n is not a multiple of 10, then the last line of output will contain fewer than 10 primes. The last function is called "usage" which I am not sure how to execute this! Your program will include a function called Usage() having signature static void Usage() that prints this message to stderr, then exits. Thus your program will contain three functions in all: main(), isPrime(), and Usage(). Each should be preceded by a comment block giving it’s name, a short description of it’s operation, and any necessary preconditions (such as those for isPrime().) And hear is my code, but I am having a bit of a problem and could you guys help me fix it? If I enter the number "5" it gives me the prime numbers which are "6,7,8,9" which doesn't make much sense. import java.util.; import java.io.; import java.lang.*; public class PrimeNumber { static boolean isPrime(int m, int[] P){ int squarert = Math.round( (float)Math.sqrt(m) ); int i = 2; boolean ans=false; while ((i<=squarert) & (ans==false)) { int c= P[i]; if (m%c==0) ans= true; else ans= false; i++; } /* if(ans ==true) ans=false; else ans=true; return ans; } ///****main public static void main(String[] args ) { Scanner in= new Scanner(System.in); int input= in.nextInt(); int i, j; int squarert; boolean ans = false; int userNum; int remander = 0; System.out.println("input: " + input); int[] prime = new int[input]; prime[0]= 2; for(i=1; i ans = isPrime(j,prime); j++;} prime[i] = j; } //prnt prime System.out.println("The first " + input + " prime number(s) are: "); for(int r=0; r }//end of main } Thanks for the help

  • Flot Pie Chart using Ajax, Php and MySql

    - by Neriza Almirol
    Good Day! Can you help me? I have a problem getting values from database. I want to control the legend. I've been googling the best approach for the pie chart, but still looking for the best answer for my problem. It's easy to query the data from the database, but I want to show it using the flot pie chart and I need it for statistic reports. From database, I need to get the percentage of Female and Male followers and separate it according to age groups. The data (dateOfbirth) is available from our database using facebook integration. Can you give me an example using Ajax, Php and MySql? Thank you! :) $.plot($("#graph_3"), graphData, { series: { pie: { show: true } }, grid: { hoverable: true, clickable: true } }); $("#graph_3").bind("plothover", pieHover); $("#graph_3").bind("plotclick", pieClick);

  • Dynamically evaluating simple boolean logic in Python

    - by a paid nerd
    I've got some dynamically-generated boolean logic expressions, like: (A or B) and (C or D) A or (A and B) A empty - evaluates to True The placeholders get replaced with booleans. Should I, Convert this information to a Python expression like True or (True or False) and eval it? Create a binary tree where a node is either a bool or Conjunction/Disjunction object and recursively evaluate it? Convert it into nested S-expressions and use a Lisp parser? Something else? Suggestions welcome.

  • jquery ui dialog fixed positioning

    - by sofia
    Hi, I needed the dialog to maintain its position fixed even if the page scrolled, so i used the extension at http://forum.jquery.com/topic/dialog-position-fixed-12-1-2010 but there's 2 problems with it: it flickers in IE and Firefox on page scroll (in Safari/Chrome it's fine) on closing and then reopening, it looses its stickyness and scrolls along with the page. Here's the code i'm using for creating the dialog: $('<div id="'+divpm_id+'"><div id="inner_'+divpm_id+'"></div><textarea class="msgTxt" id="txt'+divpm_id+'" rows="2"></textarea></div>') .dialog({ autoOpen: true, title: user_str, height: 200, stack: true, sticky: true //uses ui dialog extension to keep it fixed }); And here's the code i'm using for reopening it: jQuery('#'+divpm_id).parent().css('display','block'); Suggestions/solutions? Thanks

  • JQUery autocompleter not working properly in IE8

    - by Pete Herbert Penito
    Hi everyone! I have some script which is working in firefox and chrome but in IE 8 I get this error: $.Autocompleter.defaults = { inputClass: "ac_input", resultsClass: "ac_results", loadingClass: "ac_loading", minChars: 1, delay: 400, matchCase: false, matchSubset: true, matchContains: false, cacheLength: 10, max: 100, mustMatch: false, extraParams: {}, selectFirst: true, //the following line throws the error, read down for error message formatItem: function(row) { return row[0]; }, formatMatch: null, autoFill: false, width: 0, multiple: false, multipleSeparator: ", ", highlight: function(value, term) { return value.replace(new RegExp("(?![^&;]+;)(?!<[^<])(" + term.replace(/([\^\$()[]{}*.+\?\|\])/gi, "\$1") + ")(?![^<])(?![^&;]+;)", "gi"), "$1"); }, scroll: true, scrollHeight: 180 }; ` the specific error reads: '0' is null or not an object can I perhaps change the the row[0] to something? This is found in jquery.autocomplete.js and it reads the same in firefox and doesn't cause the error, so i don't really want to change this if at all possible. any advice would help thanks!
