  • Make object available within php functions without passing them or making them global

    - by Matt
    Hey all, This requirement is just for simplicity for developers and beautiful code. I'm building a template system and I really would just like an object variable to simply be there in all functions. Here's some code: Librarian.php: $class = "slideshow"; $function = "basic"; $args = array(...); $librarian = $this; // I WOULD LIKE THIS TO BE PRESENT IN CALLED FUNCTION ... return call_user_func($class.'::'.$function, $args); ... Slideshow.php: public static function basic($args) { echo $librarian; // "Librarian Object" } Thanks! Matt Mueller

  • Is there a better way to create an object-oriented class with jquery?

    - by Devon
    I use the jquery extend function to extend a class prototype. For example: MyWidget = function(name_var) { this.init(name_var); } $.extend(MyWidget.prototype, { // object variables widget_name: '', init: function(widget_name) { // do initialization here this.widget_name = widget_name; }, doSomething: function() { // an example object method alert('my name is '+this.widget_name); } }); // example of using the class built above var widget1 = new MyWidget('widget one'); widget1.doSomething(); Is there a better way to do this? Is there a cleaner way to create the class above with only one statement instead of two?

  • JQuery Help: toggle() is not working properly

    - by John Smith
    Hi All, I'm trying to use JQuery toggle functionality, but not able to use properly. Instead of smooth slide up and down, it goes very fast and not in an animated manner. I want to achieve sliding effect in my code, like this has (Please see Website Design, Redesign Services slider): Here is my code: HTML: <div> <div class="jquery_inner_mid"> <div class="main_heading"> <a href="#"> <img src="features.jpg" alt="" title="" border="0" /></a> </div> <div class="plus_sign"> <img id="imgFeaturesEx" src="images/plus.jpg" alt="" title="" border="0" /> <img id="imgFeaturesCol" src="images/minus.jpg" alt="" title="" border="0" /></div> <div class="toggle_container"> <div id="divMain" > </div> </div> </div> <div class="jquery_inner_mid"> <div class="main_heading"> <img src="About.jpg" alt="" title="" /></div> <div class="plus_sign"> <img id="imgTechnoEx" src="images/plus.jpg" alt="" title="" border="0" /> <img id="imgTechnoCol" src="images/minus.jpg" alt="" title="" border="0" /></div> <div class="toggle_container"> <div id="divTechnossus" > </div> </div> </div> </div> JQuery: $(function() { document.getElementById('imgFeaturesCol').style.display = 'none'; document.getElementById('imgTechnoCol').style.display = 'none'; $('#imgFeaturesEx').click(function() { $.getJSON("/Visitor/GetFeatureInfo", null, function(strInfo) { document.getElementById('divMain').innerHTML = strInfo; }); $("#divMain").toggle("slow"); document.getElementById('imgFeaturesEx').style.display = 'none'; document.getElementById('imgFeaturesCol').style.display = 'block'; }); $('#imgFeaturesCol').click(function() { document.getElementById('divMain').innerHTML = ""; $("#divMain").toggle("slow"); document.getElementById('imgFeaturesCol').style.display = 'none'; document.getElementById('imgFeaturesEx').style.display = 'block'; }); $('#imgTechnoEx').click(function() { $.getJSON("/Visitor/GetTechnossusInfo", null, function(strInfo) { document.getElementById('divTechnossus').innerHTML = strInfo; }); $("#divTechnossus").slideToggle("slow"); document.getElementById('imgTechnoEx').style.display = 'none'; document.getElementById('imgTechnoCol').style.display = 'block'; }); $('#imgTechnoCol').click(function() { document.getElementById('divTechnossus').innerHTML = ""; $("#divTechnossus").slideToggle("slow"); document.getElementById('imgTechnoCol').style.display = 'none'; document.getElementById('imgTechnoEx').style.display = 'block'; }); });

  • Strategies for Error Handling in .NET Web Services

    - by Jarrod
    I have a fairly substantial library of web services built in .NET that I use as a data model for our company web sites. In most .NET applications I use the Global ASAX file for profiling, logging, and creating bug reports for all exceptions thrown by the application. Global ASAX isn't available for web services so I'm curious as to what other strategies people have come up with to work around this limitation. Currently I just do something along these lines: <WebMethod()> _ Public Function MyServiceMethod(ByVal code As Integer) As String Try Return processCode(code) Catch ex As Exception CustomExHandler(ex) 'call a custom function every time to log exceptions Return errorObject End Try End Function Anybody have a better way of doing things besides calling a function inside the Catch?

  • javascript binding

    - by Michael
    MyObj = { ajax: null, init: function() { this.ajax = Cc["@mozilla.org/xmlextras/xmlhttprequest;1"].createInstance(); this.ajax.onload = function() { return function() {this.onload.apply(this, [null]);} }; }, onload: function () { Reader.log("I really hope I can use `this.ajax` here"); } } isn't it correct way to bind onload to MyObj? For some reason onload never called. However if I avoid binding and just put this.ajax.onload = this.onload then onload invoked. How to get binding work?

  • jQuery ajax post dynamic url insertion

    - by Kirill
    $.ajax({ type: "POST", url: "OMFG.php", data: info, success: function(){ }}); is what I'm using atm as a test and it works fine. I need to get the url from the link I'm clicking, so I do: var url = $(this).attr("href"); which works fine if I alert it out(the link includes http://samedomain.com/etc.php), but the ajax function doesn't post if I insert it into the ajax code: $.ajax({ type: "POST", url: url, data: info, success: function(){ }}); Please help, as I'm screwed without this working.

  • How do programming languages bind identifiers to functions

    - by sub
    I'm talking about C and/or C++ here as this are the only languages I know used for interpreters where the following could be a problem: If we have an interpreted language X how can a library written for it add functions to the language which can then be called from within programs written in the language? PHP example: substr( $str, 5, 10 ); How is the function substr added to the "function pool" of PHP so it can be called from within scripts? It is easy for PHP storing all registered function names in an array and searching through it as a function is called in a script. However, as there obviously is no eval in C(++), how can the function then be called? I assume PHP doesn't have 100MB of code like: if( identifier == "substr" ) { return PHP_SUBSTR(...); } else if( ... ) { ... } Ha ha, that would be pretty funny. I hope you have understood my question so far. How do interpreters solve this problem? How can I solve this for my own experimental toy interpreter?

  • Implementing password hashing/salting algorithm from crackstation.net

    - by Mason240
    I am trying to implement a password hashing/salting algorithm from crackstation.net, but I am unsure how implement it. Storing the password upon user registration seems to be as simple as passing the password into create_hash(). $password = create_hash($_POST['Password']; I'm not following how to validate upon user login. validate_password($password, $good_hash) returns either true or false, and takes $password as parameter, so it seems like a no brainer except for the second parameter $good_hash. Where does this param come from? It is my understanding that password is turned into a hash value every time its used, and that the hash value is what is stored and compared. So why would I have both the $password and $good_hash values? Quick overview of the functions: function create_hash($password){ calls pbkdf2() } function validate_password($password, $good_hash){ calls pbkdf2() calls slow_equals() } function slow_equals($a, $b){ } function pbkdf2($algorithm, $password, $salt, $count, $key_length, $raw_output = false){ } Of course a different, better method for this would also be just as helpful. Thank you

  • Jquery .val() for input only works once.

    - by Bolt_Head
    I'm trying to create a chat box for my game. The user type's their chat into the input:text feild and by ither pressing Enter or clicking the button submits the chat text. This all works, however for some reason after the first time a user submits a chat message it fails to get the text from the input field. Here is my code. $(document).ready(function() { $("#chatEnter").live('click',function(){ var chat = $('#chatText').val(); sendChat(chat); }); }); $(document).ready(function() { $("#chatText").keypress(function(e){ if ((e.which && e.which == 13) || (e.keyCode && e.keyCode == 13)) { var chat = $('#chatText').val(); sendChat(chat); return false; } else return true; }); }); function sendChat(chat) { alert(chat); //temp test alert $.getJSON("includes/boardUpdate.php",{chat: chat, bid: bid}); $('#chatText').val(""); } It doesn't matter if i first submit a text by clicking the button or pressing enter, all future attempts submit blank entrys until I refresh the page. Edit: I've tried it with and without the line to clear the text box, same results both ways. Your help is appreciated.

  • Defaults for null values

    - by OldFart
    Working on a Powershell script I had several places where I wanted A unless it was null, else B. Essentially the ?? operator in C#. I ended up writing the function shown below, but I can't help but think there is a built-in way to do this. Is there a better, built-in, way? function Get-ValueOrDefault() { foreach ($value in $args) { if ($value -ne $null) { return $value } } } I think this works better: function Get-ValueOrDefault() { $args | select -first 1 }

  • How to declare a vector or array of reducer objects in Cilk++?

    - by Jin
    Hi All, I had a problem when I am using Cilk++, an extension to C++ for parallel computing. I found that I can't declare a vector of reducer objects: typedef cilk::reducer_opadd<int> T_reducer; vector<T_reducer> bitmiss_vec; for (int i = 0; i < 24; ++i) { T_reducer r; bitmiss_vec.push_back(r); } However, when I compile the code with Cilk++, it complains at the push_back() line: cilk++ geneAttack.cilk -O1 -g -lcilkutil -o geneAttack

  • jQuery Tablesorter - column not sorting alphabetically

    - by McGirl
    I'm not sure what's going wrong here. This is the page: http://www.utexas.edu/ssw/cswr/projects/project-list/ The first column sorts, but it isn't returning data in the correct order (alphabetical). The table itself is being generated by a custom PHP function that pulls info from a WordPress database. I thought that might be the issue, but as you can see the fourth column (End Date) sorts correctly. I also thought it might be the links in the first column that were messing things up, but adding the text-extraction code from this page broke the sorting altogether. This is the jQuery code I'm current using to call Tablesorter: <script type="text/javascript" id="js"> jQuery(document).ready(function($) { $(document).ready(function() { // call the tablesorter plugin, the magic happens in the markup $("#projectTable").tablesorter({ // pass the headers argument and assing a object //debug: true, //sortList: [[0,0]], headers: { 0: { // set the column to sort as text sorter: 'text', }, // assign the secound column (we start counting zero) 1: { // disable it by setting the property sorter to false sorter: false, }, // assign the third column (we start counting zero) 2: { // disable it by setting the property sorter to false sorter: false }, 3: { sorter:'digit' } } }); // Works only with plugin modification $("#projectTable").bind("sortStart",function(e) { if( $(e.target).hasClass('header') ) { $("#overlay").show(); } }).bind("sortEnd",function(e) { if( $(e.target).hasClass('header') ) { $("#overlay").hide(); } }); }); }); </script> Thanks for your help!

  • Return value from ajax call?

    - by Dan
    Hi, I'm making a basic ajax function in jquery which echoes the number of rows found in a MySQL Query. function checkEventIDClass(id) { var params = 'method=checkEventIDClash&table=test&id=' + id; $.ajax({ type: "POST", url: "ajax.php", data: params, success: function(result){ return result; } }); } Is it possible to use this returned value in another function? I have tried but only get undefined values. In this situation, it will be acceptable to use synchronous calls. Any advice appreciated. Thanks

  • Creating a form dynamically

    - by Nathan
    Hi, I use a search button that creates a form dynamically at the server side and returns it with Jquery syntax. After I fill-up the form and click on submit button, there is another .submit() Jquery function that suppose to be called to validate input before data is sent to the server. But, for some reason, this function is never called, and the data is request is sent. In more details: This is the form that the serach button creates dynamically at the server side and "prints" to html page with Jquery: <form action=... name="stockbuyform" class="stockbuyform" method="post"> <input type=text value="Insert purchasing amount"> <input type="submit" value="Click to purchase"> </form> And here is the .submit() function : $(".stockbuyform").submit(function() { alert("Need to validate purchasing details"); } But whaen I click on purchase button, the .submit() function is never called. Does it mean that I can't use another Jquery call with the answer I got in the first call?

  • Help with jQuery issue

    - by Espen Arnoy
    I have a simple page with a list if "items". I am allowing users to vote on these items, but I only want to allow the user to vote one per. item. Therefore i have made a jQuery script that adds a class to the items the user has voted on: if(! $(this).find(".item span").hasClass("voted")) { $(".item").hover(function() { $(this).find(".ratingbar").hide(); $(this).find(".votebar").show(); }, function() { $(this).find(".votebar").hide(); $(this).find(".ratingbar").show(); }); }; This is the script that prevents the user from voting again on the same item. $(".votebutton").click(function() { $("div#"+offerid).find(".item").addClass("voted"); } My problem is that this doesn´t work. When hovering an item, the hover function still runs even though the second script successfully added the class "voted" to the html. Why can this be?

  • This regx does not work only in Chrome

    - by Deeptechtons
    Hi i just put up a validation function in jScript to validate filename in fileupload control[input type file]. The function seems to work fine in FF and sometimes in ie but never in Chrome. Basically the function tests if File name is atleast 1 char upto 25 characters long.Contains only valid characters,numbers [no spaces] and are of file types in the list. Could you throw some light on this function validate(Uploadelem) { var objRgx = new RegExp(/^[\w]{1,25}\.*\.(jpg|gif|png|jpeg|doc|docx|pdf|txt|rtf)$/); objRgx.ignoreCase = true; if (objRgx.test(Uploadelem.value)) { document.getElementById('moreUploadsLink').style.display = 'block'; } else { document.getElementById('moreUploadsLink').style.display = 'none'; } }

  • How do you make javascript code execute *in order*

    - by Ed
    Okay, so I appreciate that Javascript is not C# or PHP, but I keep coming back to an issue in Javascript - not with JS itself but my use of it. I have a function: function updateStatuses(){ showLoader() //show the 'loader.gif' in the UI updateStatus('cron1'); //performs an ajax request to get the status of something updateStatus('cron2'); updateStatus('cron3'); updateStatus('cronEmail'); updateStatus('cronHourly'); updateStatus('cronDaily'); hideLoader(); //hide the 'loader.gif' in the UI } Thing is, owing to Javascript's burning desire to jump ahead in the code, the loader never appears because the 'hideLoader' function runs straight after. How can I fix this? Or in other words, how can I make a javascript function execute in the order I write it on the page...

  • Update to Easy Slider 1.7 made all my JQuery code stop working.

    - by Anders H
    I'm pretty novice as a JQuery user goes. I've got some experience implementing different plugins but would be lost trying to customize my own. I can't share the exact site details with you due to a NDA, so I hope someone can give me a little help. I've got a project due today (Just HTML/CSS/JQuery). It has a lightbox, show/hide login menu and a slider is Easy Slider 1.5. Everything was working together, until I attempted to update to Easy Slider 1.7 (see link on same page, I'm too new to post more than 1 link). When I did so, JQuery stopped working for all the plugins. I've attempted to revert back to the original state, by undoing my work (didn't do much), ad JQuery remains broken.

  • Changing the action of a form with javascript/jquery

    - by Micah
    I'm having an issue that is driving me crazy. I'm trying to modify the openid-selector to support facebook. I'm using RPXNow as my provider so it requires the form to be submitted to a different url than the standard. For example. RpxNow requires me to setup my form like this: <form action="https://wikipediamaze.rpxnow.com/openid/start?token_url=..."> This works for every provider except for facebook and myspace. Those require the form to be posted to a different url like this: <form action="https://wikipediamaze.rpxnow.com/facebook/start?token_url=..."> and <form action="https://wikipediamaze.rpxnow.com/myspace/start?token_url=..."> The open id selector has a bunch of buttons on the form each representing the openid providers. What I'm trying to do is detect when the facebook or myspace button is clicked and changed the action on the form before submitting. However it's not working. Here is my code. I've tried several variations all with the same "not supported" exception $("#openid_form").attr("action", form_url) document.forms[0].action = form_url Any suggestions? Update Here are more details on the code. I've ommitted some for brevity. The only thing i've done is added the facebook section to the "providers_large" object (which successfully adds the logo to the website), and instead of supply a url identifying the user, I'm creating a property called "form_url" which is what I want to set the action of my form to. If you look at the section title "Provider image click" you'll see where I'm checking for the presence of the property "form_url" and using jquery to change the action and submit the form. However when I step through the javascript in debug mode it tells me it's an ivalid operation. var providers_large = { google: { name: 'Google', url: 'https://www.google.com/accounts/o8/id' }, facebook: { name: 'Facebook', form_url: 'http://wikipediamaze.rpxnow.com/facebook/start?token_url=http://www.wikipediamaze.com/Accounts/Logon' }, }; var providers_small = { myopenid: { name: 'MyOpenID', label: 'Enter your MyOpenID username.', url: 'http://{username}.myopenid.com/' }, livejournal: { name: 'LiveJournal', label: 'Enter your Livejournal username.', url: 'http://{username}.livejournal.com/' }, flickr: { name: 'Flickr', label: 'Enter your Flickr username.', url: 'http://flickr.com/{username}/' }, technorati: { name: 'Technorati', label: 'Enter your Technorati username.', url: 'http://technorati.com/people/technorati/{username}/' }, wordpress: { name: 'Wordpress', label: 'Enter your Wordpress.com username.', url: 'http://{username}.wordpress.com/' }, blogger: { name: 'Blogger', label: 'Your Blogger account', url: 'http://{username}.blogspot.com/' }, verisign: { name: 'Verisign', label: 'Your Verisign username', url: 'http://{username}.pip.verisignlabs.com/' }, vidoop: { name: 'Vidoop', label: 'Your Vidoop username', url: 'http://{username}.myvidoop.com/' }, verisign: { name: 'Verisign', label: 'Your Verisign username', url: 'http://{username}.pip.verisignlabs.com/' }, claimid: { name: 'ClaimID', label: 'Your ClaimID username', url: 'http://claimid.com/{username}' } }; var providers = $.extend({}, providers_large, providers_small); var openid = { cookie_expires: 6*30, // 6 months. cookie_name: 'openid_provider', cookie_path: '/', img_path: 'images/', input_id: null, provider_url: null, init: function(input_id) { var openid_btns = $('#openid_btns'); this.input_id = input_id; $('#openid_choice').show(); $('#openid_input_area').empty(); // add box for each provider for (id in providers_large) { openid_btns.append(this.getBoxHTML(providers_large[id], 'large', '.gif')); } if (providers_small) { openid_btns.append('<br/>'); for (id in providers_small) { openid_btns.append(this.getBoxHTML(providers_small[id], 'small', '.ico')); } } $('#openid_form').submit(this.submit); var box_id = this.readCookie(); if (box_id) { this.signin(box_id, true); } }, getBoxHTML: function(provider, box_size, image_ext) { var box_id = provider["name"].toLowerCase(); return '<a title="'+provider["name"]+'" href="javascript: openid.signin(\''+ box_id +'\');"' + ' style="background: #FFF url(' + this.img_path + box_id + image_ext+') no-repeat center center" ' + 'class="' + box_id + ' openid_' + box_size + '_btn"></a>'; }, /* Provider image click */ signin: function(box_id, onload) { var provider = providers[box_id]; if (! provider) { return; } this.highlight(box_id); this.setCookie(box_id); // prompt user for input?

  • jQuery Validation: Validating Checkboxes with Different Names

    - by Michael
    I have a set of 4 checkboxes, all with different names, and require that at least 1 is checked. I know there are a few posts on here already trying to answer this question. The solution that seems to be most logical to me is the answer posted on Question 1734840, but I can't seem to get it working! What's wrong with my code? Or any other new coding ideas to get this working? I have set the class on all of them to 'require-one'. My jQuery code is $(document).ready(function(){ $("#itemForm").validate({ highlight: function(element, errorClass, validClass) { $(element).addClass(errorClass).removeClass(validClass); $(element.form).find("label[for=" + element.name + "]") .addClass("radioerror"); }, unhighlight: function(element, errorClass, validClass) { $(element).removeClass(errorClass).addClass(validClass); $(element.form).find("label[for=" + element.name + "]") .removeClass("radioerror"); }, rules: { 'require-one': { required : { depends: function(element) { var allBoxes = $('.require-one'); if (allBoxes.filter(':checked').length == 0) { if (allBoxes.eq(element).length != 0) { return true; } } return false; } } } , }, errorPlacement: function(error, element) { if ( element.is("#other_descrip") ) error.appendTo("#othererror" ); if ( element.is("#itemlist") ) error.appendTo("#itemerror" ); } }); });

  • Iphone - UIView not displayed

    - by Raphael Pinto
    Hi, I have a strange problem with a UIView : I want to show an Activity Indicator View that I created with Interface Builder to indicate long running activity. In the viewDidLoad function of my principal viewController I init the ActivityIndicator View like this : - (void)viewDidLoad { [super viewDidLoad]; appDelegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate]; load = [[ActivityIndicatorViewController alloc] init]; ... When I push a button it call this IBAction : - (IBAction)LaunchButtonPressed{ // Show the Activity indicator view. [self.view addSubview:load.view]; // eavy work [self StartWorking]; // Hide the loading view. [load.view removeFromSuperview]; } In the StartWorking function, I ask a request to an internet serveur and parse the XML file that it return me. The problem is that if I Call my StartWorking function, the application do not start by showing the Activity Indicator view but with the StartWorking function. Whereas if I remove the call to StartWorking function, the view is shown. Is someone able to explain me why? :s
