  • Ruby - Call method passing values of array as each parameter

    - by Markus Orreilly
    I'm currently stuck on this problem. I've hooked into the method_missing function in a class I've made. When a function is called that doesn't exist, I want to call another function I know exists, passing the args array as all of the parameters to the second function. Does anyone know a way to do this? For example, I'd like to do something like this: class Blah def valid_method(p1, p2, p3, opt=false) puts "p1: #{p1}, p2: #{p2}, p3: #{p3}, opt: #{opt.inspect}" end def method_missing(methodname, *args) if methodname.to_s =~ /_with_opt$/ real_method = methodname.to_s.gsub(/_with_opt$/, '') send(real_method, args) # <-- this is the problem end end end b = Blah.new b.valid_method(1,2,3) # output: p1: 1, p2: 2, p3: 3, opt: false b.valid_method_with_opt(2,3,4) # output: p1: 2, p2: 3, p3: 4, opt: true (Oh, and btw, the above example doesn't work for me)

  • Pagination links broken - php/jquery

    - by ClarkSKent
    Hey, I'm still trying to get my pagination links to load properly dynamically. But I can't seem to find a solution to this one problem. vote down star Hi everyone, I am still trying to figure out how to fix my pagination script to work properly. the problem I am having is when I click any of the pagination number links to go the next page, the new content does not load. literally nothing happens and when looking at the console in Firebug, nothing is sent or loaded. I have on the main page 3 links to filter the content and display it. When any of these links are clicked the results are loaded and displayed along with the associated pagination numbers for that specific content. I believe the problem is coming from the sql query in generate_pagination.php (seen below). When I hard code the sql category part it works, but is not dynamic at all. This is why I'm calling $ids=$_GET['ids']; and trying to put that into the category section but then the numbers don't display at all. If I echo out the $ids variable and click on a filter it does display the correct name/id, so I don't know why this doesn't work Here is the main page so you can see how I am including and starting the function(I'm new to php): <?php include_once('generate_pagination.php'); ?> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script> <script type="text/javascript" src="jquery_pagination.js"></script> <div id="loading" ></div> <div id="content" data-page="1"></div> <ul id="pagination"> <?php //Pagination Numbers for($i=1; $i<=$pages; $i++) { echo '<li class="page_numbers" id="page'.$i.'">'.$i.'</li>'; } ?> </ul> <br /> <br /> <a href="#" class="category" id="marketing">Marketing</a> <a href="#" class="category" id="automotive">Automotive</a> <a href="#" class="category" id="sports">Sports</a> Here is the generate pagination where the problem seems to occur: <?php $ids=$_GET['ids']; include_once('config.php'); $per_page = 3; //Calculating no of pages $sql = "SELECT COUNT(*) FROM explore WHERE category='$ids'"; $result = mysql_query($sql); $count = mysql_fetch_row($result); $pages = ceil($count[0]/$per_page); ?> I thought I might as well post the jquery script if someone wants to see: $(document).ready(function(){ //Display Loading Image function Display_Load() { $("#loading").fadeIn(900,0); $("#loading").html("<img src='bigLoader.gif' />"); } //Hide Loading Image function Hide_Load() { $("#loading").fadeOut('slow'); }; //Default Starting Page Results $("#pagination li:first").css({'color' : '#FF0084'}).css({'border' : 'none'}); Display_Load(); $("#content").load("pagination_data.php?page=1", Hide_Load()); // Editing below. // Sort content Marketing $("a.category").click(function() { Display_Load(); var this_id = $(this).attr('id'); $.get("pagination.php", { category: this.id }, function(data){ //Load your results into the page var pageNum = $('#content').attr('data-page'); $("#pagination").load('generate_pagination.php?category=' + pageNum +'&ids='+ this_id ); $("#content").load("filter_marketing.php?page=" + pageNum +'&id='+ this_id, Hide_Load()); }); }); //Pagination Click $("#pagination li").click(function(){ Display_Load(); //CSS Styles $("#pagination li") .css({'border' : 'solid #dddddd 1px'}) .css({'color' : '#0063DC'}); $(this) .css({'color' : '#FF0084'}) .css({'border' : 'none'}); //Loading Data var pageNum = $(this).attr("id").replace("page",""); $("#content").load("pagination_data.php?page=" + pageNum, function(){ $(this).attr('data-page', pageNum); Hide_Load(); }); }); }); If any could assist me on solving this problem that would be great, thanks.

  • jquery validate not submitting after modal close bootstrap

    - by Mariana Hernandez
    I have a modal where i insert some data, but when i open the modal, close it, and the click the modal show button again, it doesnt submit of course because the validate is "acting" in the modal, but i closed it so its not showing... how can i prevent this? thanks it is similar to this jquery functions within modal only work on first open, after close and re-open they stop working but my functions are <script> $(document).ready(function() { $("#myModal").modal('show'); }); </script> and the validation one <script> $(document).ready(function(){ $('#form1').validate( { ignore: "", rules: { usu_login: { required: true }, usu_password: { required: true }, usu_email: { required: true }, usu_nombre1: { required: true }, usu_apellido1: { required: true }, usu_fecha_nac: { required: true }, usu_cedula: { required: true }, usu_telefono1: { required: true }, rol_id: { required: true }, dependencia_id: { required: true }, }, highlight: function(element) { $(element).closest('.grupo').addClass('has-error'); if($(".tab-content").find("div.tab-pane.active:has(div.has-error)").length == 0) { $(".tab-content").find("div.tab-pane:hidden:has(div.has-error)").each(function(index, tab) { var id = $(tab).attr("id"); $('a[href="#' + id + '"]').tab('show'); }); } }, unhighlight: function(element) { $(element).closest('.grupo').removeClass('has-error'); } }); }); </script> So i dont know how to apply the answer of the above =(

  • How to get around the jslint error 'Don't make functions within a loop.'

    - by Ernelli
    I am working on making all of our JS code pass through jslint, sometimes with a lot of tweaking with the options to get legacy code pass for now on with the intention to fix it properly later. There is one thing that jslint complains about that I do not have a workround for. That is when using constructs like this, we get the error 'Don't make functions within a loop.' for (prop in newObject) { // Check if we're overwriting an existing function if (typeof newObject[prop] === "function" && typeof _super[prop] === "function" && fnTest.test(newObject[prop])) { prototype[prop] = (function (name, func) { return function () { var result, old_super; old_super = this._super; this._super = _super[name]; result = func.apply(this, arguments); this._super = old_super; return result; }; })(prop, newObject[prop]); } This loop is part of a JS implementation of classical inheritance where classes that extend existing classes retain the super property of the extended class when invoking a member of the extended class. Just to clarify, the implementation above is inspired by this blog post by John Resig. But we also have other instances of functions created within a loop. The only workaround so far is to exclude these JS files from jslint, but we would like to use jslint for code validation and syntax checking as part of our continuous integration and build workflow. Is there a better way to implement functionality like this or is there a way to tweak code like this through jslint?

  • Javascript closures with google geocoder

    - by DaNieL
    Hi all, i still have some problems with javascript closures, and input/output variables. Im playing with google maps api for a no profit project: users will place the marker into a gmap, and I have to save the locality (with coordinates) in my db. The problem comes when i need to do a second geocode in order to get a unique pairs of lat and lng for a location: lets say two users place the marker in the same town but in different places, I dont want to have the same locality twice in the database with differents coords. I know i can do the second geocode after the user select the locality, but i want to understand what am i mistaking here: // First geocoding, take the marker coords to get locality. geocoder.geocode( { 'latLng': new google.maps.LatLng($("#lat").val(), $("#lng").val()), 'language': 'it' }, function(results_1, status_1){ // initialize the html var inside this closure var html = ''; if(status_1 == google.maps.GeocoderStatus.OK) { // do stuff here for(i = 0, geolen = results_1[0].address_components.length; i != geolen) { // Second type of geocoding: for each location from the first geocoding, // i want to have a unique [lat,lan] geocoder.geocode( { 'address': results_1[0].address_components[i].long_name }, function(results_2, status_2){ // Here come the problem. I need to have the long_name here, and // 'html' var should increment. coords = results_2[0].geometry.location.toUrlValue(); html += 'some html to let the user choose the locality'; } ); } // Finally, insert the 'html' variable value into my dom... //but it never gets updated! } else { alert("Error from google geocoder:" + status_1) } } ); I tryed with: // Second type of geocoding: for each location from the first geocoding, i want // to have a unique [lat,lan] geocoder.geocode( { 'address': results_1[0].address_components[i].long_name }, (function(results_2, status_2, long_name){ // But in this way i'll never get results_2 or status_2, well, results_2 // get long_name value, status_2 and long_name is undefined. // However, html var is correctly updated. coords = results_2[0].geometry.location.toUrlValue(); html += 'some html to let the user choose the locality'; })(results_1[0].address_components[i].long_name) ); And with: // Second type of geocoding: for each location from the first geocoding, i want to have // a unique [lat,lan] geocoder.geocode( { 'address': results_1[0].address_components[i].long_name }, (function(results_2, status_2, long_name){ // But i get an obvious "results_2 is not defined" error (same for status_2). coords = results_2[0].geometry.location.toUrlValue(); html += 'some html to let the user choose the locality, that can be more than one'; })(results_2, status_2, results_1[0].address_components[i].long_name) ); Any suggestion? EDIT: My problem is how to pass an additional arguments to the geocoder inner function: function(results_2, status_2, long_name){ //[...] } becose if i do that with a clousure, I mess with the original parameters (results_2 and status_2)

  • jQuery live() ... have to click twice to activate links?

    - by neezer
    I have the following bit of code, simply: $(function() { $('a.add-photos-link').live('click', function(e) { $(this).colorbox({ overlayClose: false, onComplete: function() { $('#add_photos').submit(function(e) { // more stuff to do e.preventDefault(); }); } }); e.preventDefault(); }); }); However, this only seems to work after single-clicking on the link TWICE. These links are dynamically added to the page (a.add-photos-link). Why is this happening and what can I do to fix it so it fires after the first single-click?

  • How to make php-closure compiler output to a predefined file name? (Updated)

    - by Mohammad
    Php-closure compiler (linked to source code) currently writes the compiled code to a md5 encoded filename. How can I make it so it write the compiled code to a predefined name like compiled_code.js? . . I think it has to do with the write() function on Line 164. It gets the filename via the _getCacheFileName() function (Line 272). function _getCacheFileName() { return $this->_cache_dir . $this->_getHash() . ".js"; } I've tried altering it to this: function _getCacheFileName() { //return $this->_cache_dir . $this->_getHash() . ".js"; return 'copiled_code.js'; } without any results. Thanks to all of you in advance!

  • Add a thousands separator to a total with Javascript or jQuery?

    - by Matt
    I have a function that sums a column of data in an html table. It does so admirably only I would like to have it put the commas in there that are needed to separate the thousands. Initially, you'll note, there are commas in the numbers being added. So that the function will add them, they are removed. How do I add the commas back in there? <script type="text/javascript"> function sumOfColumns(tableID, columnIndex, hasHeader) { var tot = 0; $("#" + tableID + " tr" + (hasHeader ? ":gt(0)" : "")) .children("td:nth-child(" + columnIndex + ")") .each(function() { tot += parseInt($(this).html().replace(',', '')); }); return "Total Pounds Entered : " + tot; } </script>

  • Problem with jQuery.ajax with 'delete' method in ie

    - by Max Williams
    I have a page where the user can edit various content using buttons and selects that trigger ajax calls. In particular, one action causes a url to be called remotely, with some data and a 'put' request, which (as i'm using a restful rails backend) triggers my update action. I also have a delete button which calls the same url but with a 'delete' request. The 'update' ajax call works in all browsers but the 'delete' one doesn't work in IE. I've got a vague memory of encountering something like this before...can anyone shed any light? here's my ajax calls: //update action - works in all browsers jQuery.ajax({ async:true, data:data, dataType:'script', type:'put', url:"/quizzes/"+quizId+"/quiz_questions/"+quizQuestionId, success: function(msg){ initializeQuizQuestions(); setPublishButtonStatus(); } }); //delete action - fails in ie function deleteQuizQuestion(quizQuestionId, quizId){ //send ajax call to back end to change the difficulty of the quiz question //back end will then refresh the relevant parts of the page (progress bars, flashes, quiz status) jQuery.ajax({ async:true, dataType:'script', type:'delete', url:"/quizzes/"+quizId+"/quiz_questions/"+quizQuestionId, success: function(msg){ alert("success"); initializeQuizQuestions(); setSelectStatus(quizQuestionId, true); jQuery("tr[id*='quiz_question_"+quizQuestionId+"']").removeClass('selected'); }, error: function(msg){ alert("error:" + msg); } }); } I put the alerts in success and error in the delete ajax just to see what happens, and the 'error' part of the ajax call is triggered, but WITH NO CALL BEING MADE TO THE BACK END (i know this by watching my back end server logs). So, it fails before it even makes the call. I can't work out why - the 'msg' i get back from the error block is blank. Any ideas anyone? Is this a known problem? I've tested it in ie6 and ie8 and it doesn't work in either. thanks - max EDIT - the solution - thanks to Nick Craver for pointing me in the right direction. Rails (and maybe other frameworks?) has a subterfuge for the unsupported put and delete requests: a post request with the parameter "_method" (note the underscore) set to 'put' or 'delete' will be treated as if the actual request type was that string. So, in my case, i made this change - note the 'data' option': jQuery.ajax({ async:true, data: {"_method":"delete"}, dataType:'script', type:'post', url:"/quizzes/"+quizId+"/quiz_questions/"+quizQuestionId, success: function(msg){ alert("success"); initializeQuizQuestions(); setSelectStatus(quizQuestionId, true); jQuery("tr[id*='quiz_question_"+quizQuestionId+"']").removeClass('selected'); }, error: function(msg){ alert("error:" + msg); } }); } Rails will now treat this as if it were a delete request, preserving the REST system. The reason my PUT example worked was just because in this particular case IE was happy to send a PUT request, but it officially does not support them so it's best to do this for PUT requests as well as DELETE requests.

  • global variable and Python

  • Auto detect internal/external development environment

    - by zaf
    We use the following function to auto detect if we are on a machine internally or on a live server and then choose the appropriate configs for various components. function devIsLocal(){ $res=false; $http_host=$_SERVER['HTTP_HOST']; if($http_host=='localhost')$res=true; if($http_host=='127.0.0.1')$res=true; if(substr($http_host,-4)=='.lan')$res=true; if(strpos($http_host, '.')===false)$res=true; return($res); } As you can see it only relies on the HTTP_HOST value. Of course, if you have use virtual host locally like example.com then the function will be tricked. Are there any other ways to fool the function? and what other variables/places could we peek at to determine where we are?

  • Unable to save to wincache from cakePHP shell

    - by Phillaf
    I'm trying to retrieve the weather from wunderground.com through their API, and store it in wincache. For testing purposes I made this function in the News model: public function updateWeather(){ $results = file_get_contents('http://api.wunderground.com/api/**api_key**/conditions/q/CA/Montreal.json'); $results = json_decode($results); return Cache::write('weather', $results); } It works fine when I call this from the controller. However, I can't figure why that same function doesn't work when called from the console. I made this shell in order to eventually add this to windows task scheduler. class WeatherShell extends AppShell { public $uses = array('News'); public function main() { $this->News->updateWeather(); } } When running this, I see that $results is correctly populated. I get 'true' from Cache::write(), however, I get 'false' when trying to read. What subtlety am I missing?

  • how to properly use jquery .stop() ?

Normally i have problem with jquery making queue for every single hover i make, and then i just keeps on animating all those hovers. I tried to implement stop() but just cant get it to work properly. This is the code i am using: <script type="text/javascript"> //<![CDATA[ $(function(){ $('#nav_menu > .center > ul > li').hover(function() { $(this).children('ul').slideToggle('slow'); },function(){ $(this).stop(true,true).children('ul').slideToggle('slow'); }).click(function(){ return false; }); }); //]]> </script> Thanks!

  • When onblur occurs, how can I find out which element focus went *to*?

    - by Michiel Borkent
    Suppose I attach an onblur function to an html input box like this: <input id="myInput" onblur="function() { ... }"></input> Is there a way to get the ID of the element which caused the onblur event to fire (the element which was clicked) inside the function? How? For example, suppose I have a span like this: <span id="mySpan">Hello World</span> If I click the span right after the input element has focus, the input element will lose its focus. How does the function know that it was mySpan that was clicked? PS: If the onclick event of the span would occur before the onblur event of the input element my problem would be solved, because I could set some status value indicating a specific element had been clicked. PPS: The background of this problem is that I want to trigger an Ajax.AutoCompleter control externally (from a clickable element) to show its suggestions, without the suggestions disappearing immediately because of the onblur event on the input element. So I want to check in the OnBlur function if one specific element has been clicked, and if so, ignore the blur event.

  • Centralized error handling in VB6.

    - by AngryHacker
    I have the following method that all the error handlers call: Public Function ToError(strClass As String, strMethod As String) As String On Error GoTo errHandle ToError = "Err " & Err.Number & _ ", Src: " & Err.Source & _ ", Dsc: " & Err.Description & _ ", Project: " & App.Title & _ ", Class: " & strClass & _ ", Method: " & strMethod & _ ", Line: " & Erl Err.Clear exitPoint: Exit Function errHandle: oLog.AddToLog "Error in ToError Method: " & Err.Description, False Resume exitPoint End Function It turns out that because I declare an error handler in this function On Error GoTo errHandle, VB6 clears the error before I am able to record it. Is there a way to prevent the 'On Error GoTo errHandle' statement from clearing the error?

  • Delphi: Fast(er) widestring concatenation

    - by Ian Boyd
    i have a function who's job is to convert an ADO Recordset into html: class function RecordsetToHtml(const rs: _Recordset): WideString; And the guts of the function involves a lot of wide string concatenation: while not rs.EOF do begin Result := Result+CRLF+ '<TR>'; for i := 0 to rs.Fields.Count-1 do Result := Result+'<TD>'+VarAsString(rs.Fields[i].Value)+'</TD>'; Result := Result+'</TR>'; rs.MoveNext; end; With a few thousand results, the function takes, what any user would feel, is too long to run. The Delphi Sampling Profiler shows that 99.3% of the time is spent in widestring concatenation (@WStrCatN and @WstrCat). Can anyone think of a way to improve widestring concatenation? i don't think Delphi 5 has any kind of string builder. And Format doesn't support Unicode. And to make sure nobody tries to weasel out: pretend you are implementing the interface: IRecordsetToHtml = interface(IUnknown) function RecordsetToHtml(const rs: _Recordset): WideString; end; Update One I thought of using an IXMLDOMDocument, to build up the HTML as xml. But then i realized that the final HTML would be xhtml and not html - a subtle, but important, difference.
