  • Item Renderer having trouble updating

    - by duder
    I have a list ItemRenderer that has 2 states. When it initializes, I set it to 1 state and listen for an event that switches it to state 2. protected function onCreationComplete(event:FlexEvent):void{ currentState = "state1"; addEventListener(CustomEvent.Event1, switch); } protected function switch(event:FlexEvent):void{ currentState = "state2"; } The difference between the 2 states is that I hide/show some labels. The problem is that it doesn't work. I still see the visual of the old state, even though if I Alert.show(currentState), it shows the correct state name. I've tried adding the line invalidateDisplayList(); inside the switch function but still no luck. protected function switch(event:FlexEvent):void{ currentState = "state2"; invalidateDisplayList(); } What am I doing wrong. Any ideas how I can get this ItemRenderer to really update?

  • Prototypes Object.extend with multiple objects that contain there own functions.

    - by erickreutz
    How would I achieve something along the lines of this.. var Persistence = new Lawnchair('name'); Object.extend(Lawnchair.prototype, { UserDefaults: { setup: function(callback) { // "save" is a native Lawnchair function that doesnt //work because // "this" does not reference "Lawnchair" // but if I am one level up it does. Say if I defined // a function called UserDefaults_setup() it would work // but UserDefaults.setup does not work. this.save({key: 'key', value: 'value'}); // What is this functions scope? // How do I access Lawnchairs "this" } }, Schedule: { refresh: function(callback) { } } }); //this get called but doesnt work.

  • Can't empty JS array....

    - by solefald
    Yes, I am having issues with this very basic (or so it seems) thing. I am pretty new to JS and still trying to get my head around it, but I am pretty familiar with PHP and have never experienced anything like this. I just can not empty this damn array, and stuff keeps getting added to the end every time i run this. I have no idea why, and i am starting to think that it is somehow related to the way chekbox id's are named, but i may be mistaking.... id="alias[1321-213]", id="alias[1128-397]", id="alias[77-5467]" and so on. I have tried sticking checkboxes = []; and checkboxes.length = 0; In every place possible. Right after the beginning of the function, at the end of the function, even outside, right before the function, but it does not help, and the only way to empty this array is to reload the page. Please tell me what I am doing wrong, or at least point me to a place where i can RTFM. I am completely out of ideas here. function() { var checkboxes = new Array(); checkboxes = $(':input[name="checkbox"]'); $.each(checkboxes, function(key, value) { console.log(value.id); alert(value.id); } ); checkboxes.length = 0; } I have also read Mastering Javascript Arrays 3 times to make sure I am not doing something wrong, but still can't figure it out....

  • PHP IP Validation Help

    - by Zubair1
    Hello, I am using this IP Validation Function that i came across while browsing, it has been working well until today i ran into a problem. For some reason the function won't validate this IP as valid: 203.81.192.26 I'm not too great with regular expressions, so would appreciate any help on what could be wrong. If you have another function, i would appreciate if you could post that for me. |--------------------------------------------| The code for the function is below: |--------------------------------------------| public static function validateIpAddress($ip_addr) { global $errors; $preg = '#^(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}' . '(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$#'; if(preg_match($preg, $ip_addr)) { //now all the intger values are separated $parts = explode(".", $ip_addr); //now we need to check each part can range from 0-255 foreach($parts as $ip_parts) { if(intval($ip_parts) > 255 || intval($ip_parts) < 0) { $errors[] = "ip address is not valid."; return false; } return true; } return true; } else { $errors[] = "please double check the ip address."; return false; } }

  • MS-Access VBA: form_error vs on error

    - by dmr
    I am trying to set up error handling for a MS-Access application. The standard method to do this seems to be with an On Error statement in each subroutine/function. It seems simpler to me to use the Form_Error function to catch all the runtime errors in that form as opposed to an On Error statement for each sub/function called by an event on that form. (Obviously, for code in modules, there is no Form_Error function and therefore the only method is the On Error statement) What are the pros and cons of using On Error vs Form_Error?

  • jqModal and jquery widget long shot

    - by rod
    Hi All, I just started playing around with jquery widgets within my jqmodals in my mvc app. I know this may be a long shot but I'll take it. Initially, I can click the Add link, get the alert ("which is the prize", watching too much tv), next click cancel to close modal and get the desired results. I can, then, click the Edit link and get the same desired results. However, if I click Edit link first then I try to click the Add link, "forget about it" I don't get the alert (which means my widget did not init). But I can still go back and click Edit and get the prize (the alert message). ajax: "/Home/EditPrintAdLine" and ajax: "/Home/AddPrintAdLine" render the same web user control Any ideas? <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %> <asp:Content ID="indexTitle" ContentPlaceHolderID="TitleContent" runat="server"> Home Page </asp:Content> <asp:Content ID="indexContent" ContentPlaceHolderID="MainContent" runat="server"> <h2><%= Html.Encode(ViewData["Message"]) %></h2> <p> To learn more about ASP.NET MVC visit <a href="http://asp.net/mvc" title="ASP.NET MVC Website">http://asp.net/mvc</a>. </p> <div id="printAdLineEditDialog" class="jqmWindow"></div> <div id="printAdDialog" class="jqmWindow"></div> <table> <tr><td><a id="printAdLineItem" href="#">Add a Line Item</a></td></tr> <tr><td><a id="editPrintAdLine" href="#">Edit</a></td></tr> </table> <script type="text/javascript"> $(document).ready(function() { $.widget("ui.my_widget", { _init: function() { alert("My widget was instantiated"); } }); // Add line $('#printAdLineItem').click(function(e) { $('#printAdDialog').jqmShow(this); e.preventDefault(); }); $('#printAdDialog').jqm({ ajax: "/Home/AddPrintAdLine", onLoad: function(hash) { $('#PrintAdLine_RunDate').my_widget(); } }); // Edit line $('#editPrintAdLine').click(function(e) { $('#printAdLineEditDialog').jqmShow(this); e.preventDefault(); }); $('#printAdLineEditDialog').jqm({ ajax: "/Home/EditPrintAdLine", onLoad: function(hash) { $('#PrintAdLine_RunDate').my_widget(); } }); }); </script> </asp:Content>

  • Why wont this JS code work if its all on the same line?

    - by culov
    I'm writing HTML code for a java servlet. i first write the code in html/js so i can debug what im working on, and then ill make it a java string and put it in my servlet. My problem is that the code is working fine when i view it in ff from a local html file, but when i view it on my java servlet, it doesnt work because the js isnt getting called. what I did was format the html that my servlet generated so that its not all on a single line and ran the code again. This time it worked. I copied this working code into a browser address bar so that it will all be on a single line, and copied that code back into the script in my html file. Now, when the previously working code is on a single line, it doesnt work. Here's the formatted JS: var sMax var holder; var preSet; var rated; var request; function rating(num){ sMax = 0; for(n=0; n<num.parentNode.childNodes.length; n++){ if(num.parentNode.childNodes[n].nodeName == "A"){ sMax++; } } if(!rated){ s = num.id.replace("_", ''); a = 0; for(i=1; i<=sMax; i++){ if(i<=s){ document.getElementById("_"+i).className = "on"; document.getElementById("rateStatus").innerHTML = num.title; holder = a+1; a++; }else{ document.getElementById("_"+i).className = ""; } } } } function off(me){ if(!rated){ if(!preSet){ for(i=1; i<=sMax; i++){ document.getElementById("_"+i).className = ""; document.getElementById("rateStatus").innerHTML = me.parentNode.title; } }else{ rating(preSet); document.getElementById("rateStatus").innerHTML = document.getElementById("ratingSaved").innerHTML; } } } function rateIt(me){ if(!rated){ document.getElementById("rateStatus").innerHTML = document.getElementById("ratingSaved").innerHTML + " "+me.title; preSet = me; rated=1; sendRate(me); rating(me); } } function sendRate(sel){ alert("Your rating was: "+sel.title); addRating("rating", "?truck=kogibbq?rating="+ sel.id); } function addRating(servletName, servletArguments){ var servlet = servletName; var arg = servletArguments var req = servlet + arg; alert(req); addrequest(req); request.onreadystatechange = function(){ alert("response received"); } } function addrequest(req) { try { request = new XMLHttpRequest(); }catch (e) { try { request = new ActiveXObject("Microsoft.XMLHTTP"); }catch (e) { alert("XMLHttpRequest error: " + e); } } request.open("GET", element, true); request.send(null); return request; } Thanks.

  • Handling file uploads with JavaScript and Google Gears, is there a better solution?

    - by gnarf
    So - I've been using this method of file uploading for a bit, but it seems that Google Gears has poor support for the newer browsers that implement the HTML5 specs. I've heard the word deprecated floating around a few channels, so I'm looking for a replacement that can accomplish the following tasks, and support the new browsers. I can always fall back to gears / standard file POST's but these following items make my process much simpler: Users MUST to be able to select multiple files for uploading in the dialog. I MUST be able to receive status updates on the transmission of a file. (progress bars) I would like to be able to use PUT requests instead of POST I would like to be able to easily attach these events to existing HTML elements using JavaScript. I.E. the File Selection should be triggered on a <button> click. I would like to be able to control response/request parameters easily using JavaScript. I'm not sure if the new HTML5 browsers have support for the desktop/request objects gears uses, or if there is a flash uploader that has these features that I am missing in my google searches. An example of uploading code using gears: // select some files: var desktop = google.gears.factory.create('beta.desktop'); desktop.openFiles(selectFilesCallback); function selectFilesCallback(files) { $.each(files,function(k,file) { // this code actually goes through a queue, and creates some status bars // but it is unimportant to show here... sendFile(file); }); } function sendFile(file) { google.gears.factory.create('beta.httprequest'); request.open('PUT', upl.url); request.setRequestHeader('filename', file.name); request.upload.onprogress = function(e) { // gives me % status updates... allows e.loaded/e.total }; request.onreadystatechange = function() { if (request.readyState == 4) { // completed the upload! } }; request.send(file.blob); return request; } Edit: apparently flash isn't capable of using PUT requests, so I have changed it to a "like" instead of a "must".

  • Chord Chart - Skip to key with a click

    - by Juan Gonzales
    I have a chord chart app that basically can transpose a chord chart up and down throughout the keys, but now I would like to expand that app and allow someone to pick a key and automatically go to that key upon a click event using a function in javascript or jquery. Can someone help me figure this out? The logic seems simple enough, but I'm just not sure how to implement it. Here are my current functions that allow the user to transpose up and down... var match; var chords = ['C','C#','D','D#','E','F','F#','G','G#','A','A#','B','C','Db','D','Eb','E','F','Gb','G','Ab','A','Bb','B','C']; var chords2 = ['C','Db','D','Eb','E','F','Gb','G','Ab','A','Bb','B','C','C#','D','D#','E','F','F#','G','G#','A','A#','C']; var chordRegex = /(?:C#|D#|F#|G#|A#|Db|Eb|Gb|Ab|Bb|C|D|E|F|G|A|B)/g; function transposeUp(x) { $('.chord'+x).each(function(){ ///// initializes variables ///// var currentChord = $(this).text(); // gatheres each object var output = ""; var parts = currentChord.split(chordRegex); var index = 0; ///////////////////////////////// while (match = chordRegex.exec(currentChord)){ var chordIndex = chords2.indexOf(match[0]); output += parts[index++] + chords[chordIndex+1]; } output += parts[index]; $(this).text(output); }); } function transposeDown(x){ $('.chord'+x).each(function(){ var currentChord = $(this).text(); // gatheres each object var output = ""; var parts = currentChord.split(chordRegex); var index = 0; while (match = chordRegex.exec(currentChord)){ var chordIndex = chords2.indexOf(match[0],1); //var chordIndex = $.inArray(match[0], chords, -1); output += parts[index++] + chords2[chordIndex-1]; } output += parts[index]; $(this).text(output); }); } Any help is appreciated. Answer will be accepted! Thank You

  • How to properly read 16 byte unsigned integer with BinaryReader

    - by Brent
    I need to parse a binary stream in .NET to convert a 16 byte unsigned integer. I would like to use the BinaryReader.ReadUIntXX() functions but there isn't a BinaryReader.ReadUInt128() function available. I assume I will have to roll my own function using the ReadByte function and build an array but I don't know if this is the most efficient method? Thanks!

  • jQuery: Use of undefined constant data assumed 'data'

    - by morpheous
    I am trying to use jQuery to make a synchronous AJAX post to a server, and get a JSON response back. I want to set a javascript variable msg upon successful return This is what my code looks like: $(document).ready(function(){ $('#test').click(function(){ alert('called!'); jQuery.ajax({ async: false, type: 'POST', url: 'http://www.example.com', data: 'id1=1&id2=2,&id3=3', dataType: 'json', success: function(data){ msg = data.msg; }, error: function(xrq, status, et){alert('foobar\'d!');} }); }); [Edit] I was accidentally mixing PHP and Javascript in my previous xode (now corrected). However, I now get this even more cryptic error message: uncaught exception: [Exception... "Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsIXMLHttpRequest.open]" nsresult: "0x80070057 (NS_ERROR_ILLEGAL_VALUE)" location: "JS frame :: http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js :: anonymous :: line 19" data: no] What the ... ?

  • Help with my PHP template class

    - by blerh
    I want to separate the output of HTML from my program code in my projects, so I wrote a very simple database class. <?php class Template { private $template; function load($filePath) { if(!$this->template = file_get_contents($filePath)) $this->error('Error: Failed to open <strong>' . $filePath . '</strong>'); } function replace($var, $content) { $this->template = str_replace("{$var}", $content, $this->template); } function display() { echo $this->template; } function error($errorMessage) { die('die() by template class: <strong>' . $errorMessage . '</strong>'); } } ?> The thing I need help with is the display() method. Say for example I use this code: $tplObj = new Template(); $tplObj->load('index.php'); $tplObj->replace('{TITLE}', 'Homepage'); $tplObj->display(); And the index.php file is this: <html> <head> <title>{TITLE}</title> </head> <body> <h1>{TITLE}</h1> <?php if($something) { echo '$something is true'; } else { echo '$something is false'; } ?> </body> </html> I'm just wondering if the PHP code in there would be run? Or would it just be sent to the browser as plaintext? I was using eval() in my template class but I hate that function :P Thanks.

  • Why is the event object different coming from jquery bind vs. addEventListener

    - by yodaisgreen
    Why is it when I use the jQuery bind the event object I get back is different from the event object I get back using addEventListener? The event object resulting from this jQuery bind does not have the targetTouches array (among other things) but the event from the addEventListener does. Is it me or is something not right here? $(document).ready (function () { $("#test").bind("touchmove", function (event) { console.log(event.targetTouches[0].pageX); // targetTouches is undefined }); }); vs. $(document).ready (function () { var foo = document.querySelectorAll('#test') foo[0].addEventListener('touchmove', function (event) { console.log(event.targetTouches[0].pageX); // returns the correct values }, false); });

  • trying to fade out a top div on hover to reveal working links in text below using JQuery

    - by Heath
    I need to fade a div (and image) to reveal a div underneath (text with clickable links) using jQuery. <script> $(document).ready(function(){ $("img.a").hover( function() { $(this).stop().animate({"opacity": "0"}, "slow"); }, function() { $(this).stop().animate({"opacity": "1"}, "slow"); }); }); </script> Used the above code and all worked well, until I went to click the links. Seems the top hidden div is preventing me from doing so. Tried the replaceWith function and that allowed me to click the links too - but couldn't get it to go back to showing original div when I moused out. Also, bossman wants the transition to be gradual - like a fade... Any suggestions? Many thanks! Heath

  • capistrano still asks for the 1st password even though I've set up an ssh key???

    - by Greg
    Hi, Background: I've setup an ssh key to avoid having to use passwords with capistrano per http://www.picky-ricky.com/2009/01/ssh-keys-with-capistrano.html. A basic ssh to my server does work fine without asking for passwords. I'm using "dreamhost.com" for hosting. Issue - When I run 'cap deploy' I still get asked for the 1st password (even through the previous 2nd and 3rd password requests are now automated). It is the capistrano command that start with "git clone - q ssh:....." for which the password is being requested. Question - Is there something I've missed? How can I get "cap deploy" totally passwordless? Some excerts from config/deploy.rb are: set :use_sudo, false ssh_options[:keys] = [File.join(ENV["HOME"], ".ssh", "id_rsa")] default_run_options[:pty] = true thanks PS. The permissions on the server are: drwx------ 2 mylogin pg840652 4096 2010-02-22 15:56 .ssh -rw------- 1 mylogin pg840652 404 2010-02-22 15:45 authorized_keys

  • Modify jkpanel to load internal content instead of external content

    - by Adam Stone
    I am using an implementation of jkpanel in a vb.net app, the script (see below) loads an external file into the drop down panel. I need to modify this script to load an internal content like a specific div or span so that I can have this nested within the master page. //Drop Down Panel script (March 29th, 08'): By JavaScript Kit: http://www.javascriptkit.com var jkpanel={ controltext: 'Panel Content', $mainpanel: null, contentdivheight: 0, openclose:function($, speed){ this.$mainpanel.stop() //stop any animation if (this.$mainpanel.attr('openstate')=='closed') this.$mainpanel.animate({top: 0}, speed).attr({openstate: 'open'}) else this.$mainpanel.animate({top: -this.contentdivheight+'px'}, speed).attr({openstate: 'closed'}) }, init:function(file, height, speed){ jQuery(document).ready(function($){ jkpanel.$mainpanel=$('<div id="dropdownpanel"><div class="contentdiv"></div><div class="control">'+jkpanel.controltext+'</div></div>').prependTo('body') var $contentdiv=jkpanel.$mainpanel.find('.contentdiv') var $controldiv=jkpanel.$mainpanel.find('.control').css({cursor: 'wait'}) $contentdiv.load(file, '', function($){ var heightattr=isNaN(parseInt(height))?

  • JavaScript on jQuery created code never gets called

    - by mare
    This is my view in ASP.NET MVC. <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Administration.Master" Inherits="System.Web.Mvc.ViewPage" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="HeadContent" runat="server"> <script type="text/javascript"> var ddlContentTypes; $(document).ready(function () { ddlContentTypes = $("#ContentTypes"); ddlContentTypes.bind("change", loadCreate); loadCreate(); }); function loadCreate() { var typeId = $("#ContentTypes option:selected").val(); $.get('~/' + typeId + '/Create', function (data) { $("#CreateForm").html(data); }); $("fieldset input").each(function (index, item) { $(item).attr("disabled", true); }); } </script> </asp:Content> <asp:Content ID="Content3" ContentPlaceHolderID="MainContent" runat="server"> <h2> <%=Resources.Localize.CreateWidget %></h2> <p> <% Html.RenderPartial("ContentTypeSelector"); %></p> <div id="CreateForm"> </div> </asp:Content> As you can see, it loads some HTML (actually user control) and adds it to the CreateForm div. This actually works fine. The problem is this $("fieldset input").each(function (index, item) { $(item).attr("disabled", true); }); never runs. The fieldset tag is in the response, so you don't see it here but it's there - everything is returned back fine (I checked with Firebug). Why do the above two lines of JS never run or have any effect?

  • JQuery animate div "like" a Zoom

    - by Russell Parrott
    I can never get these to work - sorry - but I I am trying to animate on a mouse over then "re-animate" on a mouse out. I can never get $('#xyz').hover(function(){'something',function(){'somethingelse'}); to work. Hope you guys can help. What I am trying to do is animate + and - 20px (top and left) on some absolutely positioned divs and then add 40px to the width height returning to the original position/width/height on mouse out. I haven't even got to the css widths/heights yet .... Here is my code (which is wrong - well it must be as it doesn't work :-) ) $('.box').hover(function(){ $(this).animate({'top':'-20','left':'-20'},function(){ $(this).animate({'top':'20','left':'20' }); }); Help really appreciated.

  • Extending a jquery plugins event callback

    - by Greg J
    I'm extending the functionality of a jquery plugin (foo) with another jquery plugin (bar). Essentially, the first plugin specifies an onReady(): var foo = $.foo({ onReady: function() { alert('foo'); }}); Foo is sent to bar as a parameter to bar: var bar = $.bar(foo); I want bar to be able to hook into foo's onReady event: (function($) { $.extend({ bar: function(foo) { var foo = foo; // How to do alert('bar') when foo.onready is called? } }); })(jQuery); I can override foo's onready event: foo.onready = function() { alert('bar'); } But I don't want to override it, I want to extend it so that I'll see both alerts when foo is ready. Thanks in advance!

  • Using argument (this) passed via element eventhandler

    - by Kel
    Hey guys, I want to use the argument I pass (this) in a JS function and treat it as an jQuery variable. Example: <script> function useMe(obj){ $(obj).val(); ... ... ... } </script> <select id="selectid" onChange="useMe(this)"> <option>......</option> </select> Is there a possibility to treat the passed argument as a jQuery element? Btw. I need to do it this way, because the select-element isn't created on load. The select element will be created later asynchronously. So, this won't work: $("select").each(function (i){ var select_id = $(this).attr("id"); $(this).change(function(e){ because it doesn't exist yet. Thanks for your help.

  • which is the most secure way to check variables type javascript

    - by mck89
    Hi, i need to check the type of a variable in javascript, i know 3 ways to do it: instanceof operator: if(a instanceof Function) typeof operator: if(typeof a=="function" toString method (jQuery uses this): Object.prototype.toString.call(a) == "[object Function]" Which is the most secure way to do type checking beetween these solutions? and why? Please don't tell me that the last solution is better only because jQuery uses that.
