  • Hide table rows if Cookie is there

    - by kuswantin
    Based on my previous question here and here, I found that I can set a cookie with javascript. I want to combine it with jquery to have a cookie state set for toggled table rows. I want to keep the hidden rows hidden upon reload. Here is what I have achieved so far: // Load cookies if any if(readCookie('togState')) { $('table#toggle tr.' + readCookie('togState')).hide(); } $(function() { $('table#toggle tr.container').click(function() { var idTog = $(this).attr('id'); $(this).toggleClass('off').nextAll('.' + idTog).toggle(); setCookie('togState', idTog, 30); alert('Cookies: ' + readCookie('togState')); }); }); As you can see the cookie is read, but is not set upon browser refresh. What am I doing wrong? What I want is hide any toggled rows (having their classes equal to their parent's container ID), if the parent container is clicked, and so the cookie is set. Any help would be very much appreciated. Thanks.

  • IF-block brackets: best practice

    - by MasterPeter
    I am preparing a short tutorial for level 1 uni students learning JavaScript basics. The task is to validate a phone number. The number must not contain non-digits and must be 14 digits long or less. The following code excerpt is what I came up with and I would like to make it as readable as possible. if ( //set of rules for invalid phone number phoneNumber.length == 0 //empty || phoneNumber.length > 14 //too long || /\D/.test(phoneNumber) //contains non-digits ) { setMessageText(invalid); } else { setMessageText(valid); } A simple question I can not quite answer myself and would like to hear your opinions on: How to position the surrounding (outermost) brackets? It's hard to see the difference between a normal and a curly bracket. Do you usually put the last ) on the same line as the last condition? Do you keep the first opening ( on a line by itself? Do you wrap each individual sub-condition in brackets too? Do you align horizontally the first ( with the last ), or do you place the last ) in the same column as the if? Do you keep ) { on a separate line or you place the last ) on the same line with the last sub-condition and then place the opening { on a new line? Or do you just put the ) { on the same line as the last sub-condition? Community wiki.

  • Multiple use of a form before it is submitted

    - by OregonTrail
    I'm new to JavaScript, and trying to figure out the canonical way to do the following. I have a form with some checkboxes and a selector. Let's say the checkboxes are styles of music and the selector is for people's names. I'd like the user to be able to select the styles of music for each of the people's names and then submit the form with all of the data. For example, the user might first check off Classical, Jazz, Rock, and Pop and choose "Joe", then select Jazz, Pop, Country, and Electronica and choose "Jane". So there would have to be two different buttons for "submit person" and "submit form". I would like to: Have a list of the names and their chosen styles populate below the form, for feedback Allow the user to use the form as much as they want, and then submit all the data at the end I get the feeling that using jquery and JSON is perfect for this, but I'm not sure what search terminology to use to figure out how to do this. If it matters, the form will be processed by a Django view in Python.

  • Generate random number from an arbitrary weighted list

    - by Fernando
    Here's what I need to do, I'll be doing this both in PHP and JavaScript. I have a list of numbers that will range from 1 to 300-500 (I haven't set the limit yet). I will be running a drawing were 10 numbers will be picked at random from the given range. Here's the tricky part: I want some numbers to be less likely to be drawn up. A small set of those 300-500 will be flagged as "lucky numbers". For example, out of 100 drawings, most numbers have equal chances of being drawn, except for a few, that will only be picked once every 30-50 drawings. Basically I need to artificially set the probability of certain numbers to be picked while maintaining an even distribution with the rest of the numbers. The only similar thing I've found so far is this question: Generate A Weighted Random Number, the problem being that my spec has considerably more numbers (up to 500) so the weights would get very small and supposedly this could be a problem with that solution (Rejection Sampling). I'm still trying it, though, but I wonder if there other solutions. Math is not my thing so I appreciate any input. Thanks.

  • Are all of the default scripts loaded by Magento really needed?

    - by pxl
    Here's a listing of all the scripts loaded by Magento by default: ../js/prototype/prototype.js //prototype library ../js/prototype/validation.js //don't know what this does ../js/scriptaculous/builder.js //don't know what this does ../js/scriptaculous/effects.js //base scriptaculous effects library? ../js/scriptaculous/dragdrop.js //component of scriptaculous effects ../js/scriptaculous/controls.js //not sure? ../js/scriptaculous/slider.js //more scriptaculous effects ../js/varien/js.js //don't know what this is ../js/varien/form.js //form validation scripts? ../js/varien/menu.js //menu/drop down menu scripts ../js/mage/translate.js //don't know what this does ../js/mage/cookies.js //don't know what this does these scripts total 316.8K of javascript... all in various states of being minified (for example, prototype.js isn't minified). So my first question: 1) Aside from prototype.js, are all of the others really that needed? and 2) What is the "correct" way to remove these scripts? Layout updates? Or hardcoded in templates? I want to make the loading of my magento site as light weight as possible. thanks!

  • Is there a Firebug console -vsdoc.js?

    - by David Murdoch
    If not, does anyone care to write one? I would do it myself...but I don't have time right now...maybe next week (unless someone beats me to it). If you are bored and want to compile the vsdoc: Here is the Firebug API. Here is a blog post about the format for VS doc comments for intellisense. Here is an example vsdoc (jquery-1.4.1-vsdoc.js). I created the following because I kept typing cosnole instead of console. You can use it as a starting point (ish). console = { /// <summary> /// 1: The javascript console /// </summary> /// <returns type="Object" /> }; console.log = function (object) { /// <summary> /// Write to the console's log /// </summary> /// <returns type="null" /> /// <param name="object" type="Object"> /// Write the object to the console's log /// </param> };

  • jquery change event not working with IE6

    - by manivineet
    It is indeed quite unfortunate that my client still uses IE6. using jquery 1.4.2 The problem is that I open a window using a click event and do some edit operation in the new window. I have a 'change' event attached to the row of a table which has input fields. Now when the window loads for the first time and I make a change in the input for the FIRST time, the change event does not fire. however, on a second try it starts working. I have noticed that I e.g. I run a dummy page, i.e. create a new page(i work with visual studio) and run that page individually , the 'change' event works just fine. what it going on? and what can i do, besides going back to 1.3.2 (by the way that doesn't work either, but haven't fully tested it yet) <!--HTML--> <table id="tbReadData"> <tr class="nenDataRow" id="nenDr2"> <td> <input type="text" class="nenMeterRegister" value="1234" /> </td> <tr /> <table> <script type="text/javascript"> $(document).ready(function(){ $('#tbReadData').find('tr').change(function() { alert('this works'); } }); </script>

  • jquery.append() - only the last element of my list is appended, previous ones are erased

    - by jaes
    Hi, I have a page like this : <div id="daysTable"> <div id="day0" class="day"></div> <div id="day1" class="day"></div> <div id="day2" class="day"></div> <div id="day3" class="day"></div> <div id="day4" class="day"></div> <div id="day5" class="day"></div> <div id="day6" class="day"></div> </div> and some javascript to fill my calendar like this function getWeek(){ $.getJSON("/getWeek",function(events){ var eventHeight = $("#hoursTable > div").height(); var eventWidth = $("#daysTable > div").width(); var startWeek = events[0]// timestamp of the start of the week for(var i = 1; i < events.length; i ++){ $(".day").empty(); var startHour = (events[i].startDate - startWeek)/3600 var duration = (events[i].stopDate - startWeek)/3600 - startHour var dayStart = Math.floor(startHour/24); var startHour = startHour - dayStart * 24 divEvent = $('<div id="event'+events[i].idEvent+'"/>') .width(eventWidth-2) .height(duration*eventHeight) .css("border","1px solid black") .css("margin-top",startHour*eventHeight) .html(events[i].name); divEvent.appendTo("#day"+dayStart); console.log(divEvent); } }); } my problem being : events contain 3 element I'd like to display but only the last is displayed. If I stop my "for" at the first iteration I can see the first div appended, but it seems that if my loop goes for three iteration the two previous are deleted. The console.log() display some "not-anymore" existing element. Any idea ?

  • Syntax Error? When parsing XML value

  • colorbox not displaying first caption from flickr gallery integration

    - by Mark
    I am pulling small thumbnails into my page from the flickr API, and using Colorbox to display larger thumbnails and captions from the title attribute. Using the API with C#. However, on the first instance of opening colorbox it does not display the caption from the anchors title attribute. If you click next or previous then it appears. The actual caption is physically there in the source code, just not getting put into the colorbox window. Demo here, if you click on a thumbnail you will see there is no caption, click next then prev and it will appear. Here's the code: <script type="text/javascript"> $(function() { $("a[rel='group']").colorbox({ opacity: 0.75 }); }); </script> <a href='http://farm6.static.flickr.com/5015/5511378425_e63d4a62f7.jpg' title='Little Hermit (Peter Dunn)' rel='group' class='tooltip'> <img src='http://farm6.static.flickr.com/5015/5511378425_e63d4a62f7_s.jpg' alt='Little Hermit (Peter Dunn)' /> </a> If i view source, the title attribute is populated with the caption, but if i ook in firebug it is not in the colorbox code. Any help on this would be great Ive ran out of ideas!

  • Difference in clientX and clientY when going out of the browser on ie/ff

    - by Py
    I just ran into a little problem with clientX and clientY. I put a little event to detect if the mouse goes out of the window and to know where it exits. And there come the trouble, it works fine with firefox, but only sends -1 as an answer in IE. Does someone know if there is a way to solve easily that problem and that without using a framework? A little bit of code to reproduce that: <html> <head> <script type="text/javascript"> document.onmouseout=function(e){ if (!e) var e = window.event; var relTarg = e.relatedTarget || e.toElement; if (!relTarg){ document.getElementById('result1').innerHTML="e.clientY:"+e.clientY+" e.clientX:"+e.clientX; } }; </script> </head> <body> <div id="result1">Not Yet</div> </body> </html> the results if I exit through the left of the window are: e.clientY:302 e.clientX:-130 on firefox e.clientY:-1 e.clientX:-1 on ie. Thanks in advance.

  • I would like to interactively detect when an ActiveX component has been installed, and asynchronousl

    - by Brian Stinar
    Hello, I am working on a website, and I would like to refresh a portion of the page after an ActiveX component has been installed. I have a general idea of how to do this with polling, which I am working on getting going : function detectComponentThenSleep(){ try{ // Call what I want ActiveX for, if the method is available, or // ActiveXComponent.object == null --- test for existance document.getElementById("ActiveXComponent").someMethod(); } catch{ // Try again, if the method is not available setTimeout(detectComponentThenSleep, 100); } } However, what I would REALLY like to do is something like this: ActiveXObject.addListener("onInstall", myfunction); I don't actually have the source for the ActiveX component, but I have complete control of the page I am hosting it on. I would like to use JavaScript, if possible, to accomplish this. So, my question is 1.) will this actually work with the polling method? and 2.) Is there an interrupt/listener like way of doing this? I am sure I am missing something with connecting the dots here, I can already detect if the component is present, but I am having trouble doing this asynchronously. Thank you very much for your time and help, -Brian J. Stinar-

  • How to run setInterval() on multiple canvases simultaneously?

    - by Alex
    I have a page which has several <canvas> elements. I am passing the canvas ID and an array of data to a function which then grabs the canvas info and passes the data onto a draw() function which in turn processes the given data and draws the results onto the canvas. So far, so good. Example data arrays; $(function() { setup($("#canvas-1"), [[110,110,100], [180,180,50], [220,280,80]]); setup($("#canvas-2"), [[110,110,100], [180,180,50], [220,280,80]]); }); setup function; function setup(canvas, data) { ctx = canvas[0].getContext('2d'); var i = data.length; var dimensions = { w : canvas.innerWidth(), h : canvas.innerHeight() }; draw(dimensions, data, i); } This works perfectly. draw() runs and each canvas is populated. However - I need to animate the canvas. As soon as I replace line 8 of the above example; draw(dimensions, data, i); with setInterval( function() { draw(dimensions, data, i); }, 33 ); It stops working and only draws the last canvas (with the others remaining blank). I'm new to both javascript and canvas so sorry if this is an obvious one, still feeling my way around. Guidance in the right direction much appreciated! Thanks.

  • My jQuery and PHP give different results on the same thing?

    - by Stefan
    Hey all, Annoying brain numbing problem. I have two functions to check the length of a string (primarily, the js one truncates as well) heres the one in Javascript: $('textarea#itemdescription').keyup(function() { var charLength = $(this).val().length; // Displays count $('span#charCount').css({'color':'#666'}); $('span#charCount').html(255 - charLength); if($(this).val().length >= 240){ $('span#charCount').css({'color':'#FF0000'}); } // Alerts when 250 characters is reached if($(this).val().length >= 255){ $('span#charCount').css({'color':'#FF0000'}); $('span#charCount').html('<strong>0</strong>'); var text = $('textarea#itemdescription').val().substring(0,255) $('textarea#itemdescription').val(text); } }); And here is my PHP to double check: if(strlen($_POST["description"])>255){ echo "Description must be less than ".strlen($_POST["description"])." characters"; exit(); } I'm using jQuery Ajax to post the values from the textarea. However my php validation says the strlen() is longer than my js is essentially saying. So for example if i type a solid string and it says 0 or 3 chars left till 255. I then click save and the php gives me the length as being 261. Any ideas? Is it to do with special characters, bit sizes that js reads differently or misses out? Or is it to do with something else? Maybe its ill today!... :P Thanks, Stefan

  • key-words highlight in <textarea> (again)

    - by Halst
    Wait, I know! I know that this "syntax highlight in textarea"-question was raised like a million times on stackoverflow! But, please, listen. offtopic: I'm not a web-developer, and technically I'm not a programmer at all. I study mechatronics and deal mostly with control-engineering and digital-hardware. And I'm so pissed off that whenever I want to share some application (that would be helpful in my field) and embed it into the web, I need to know such a crazy amount of technologies, like html, css, javascript, flash, etc.. that takes time, which I could have been spending for the benefit of my own field. Right now I'm playing with hardware-description-languages and I'm writing some Python-libraries to convert one HDL into another. And I wanted to embed such feature on the web: http://xhdl2vhdl.appspot.com/ I wanted to implement some basic syntax highlighting (only keywords highlighting will be enough) so that the code could be readable. But the whole idea highlighting something in textarea is not trivial at all. The other difficulty is that the languages I work with are rare, and there are no out-of-box solutions for them. I tried to dig into these solutions, but they are very complicated for me: http://www.nicolarizzo.com/gamesroom/experimental/CodeEditor.html http://marijn.haverbeke.nl/codemirror/jstest.html and there is no clear descriptions how to use them (for my level of knowledge of web-development). So, is there a simple solution, just to highlight a bunch of key-words in textarea or perform something equivalent? Thank you.

  • how do Google and Yahoo replace the URL in the browser status bar?

    - by Mike W
    On the Google and Yahoo search pages, the URLs of the 10 search result links actually point to google.com or yahoo.com. The URLs have extra arguments that allow google.com or yahoo.com to redirect to the actual search result when the link is clicked. When the user mouses over the link, the search result URL (and not the google.com or yahoo.com URL) is displayed in the browser's status bar. I'm wondering how they do that. Many years ago, this would have been accomplished by having some javascript that sets window.status, but that doesn't seem to work anymore, as is explained by http://stackoverflow.com/questions/876390/reliable-cross-browser-way-of-setting-status-bar-text I have a link that looks like this: <a href="http://somedomain.com/ReallyLongURLThatShouldNotBeSeenInTheStatusBar" onmouseover="window.status='http://niceShourtUrl.com/'" onmouseout="window.status=''">Click Me</a> This link tried to use the window.status strategy, but it doesn't work. How do I fix this link so that it acts like the links on Google's and Yahoo's search result pages? In this example, I want "http://niceShourtUrl.com/" to be displayed in the status bar when the user mouses over the link.

  • Pre-populate iPhone Safari SQLite DB

    - by Matt Rogish
    I'm working with a PhoneGap app that uses Safari local storage (SQlite DB) via Javascript: http://developer.apple.com/safari/library/documentation/iPhone/Conceptual/SafariJSDatabaseGuide/UsingtheJavascriptDatabase/UsingtheJavascriptDatabase.html On first load, the app creates the database, tables, and populates the data via a series of INSERT statements. If the user closes the app while this processing is happening, then my app database is left in an inconsistent state. What I prefer to do is deploy the SQLite DB as part of my iTunes App packaging so nothing must be populated at app cold start. However, I'm not sure if that is possible -- all of the google hits for this topic that I can find are referring to the core-data provided SQLite which is not what we're using... If it's not possible, could I wrap the entire thing in a transaction and keep re-trying it when the app is restarted? Failing that, I guess I can create a simple table with one boolean column "is_app_db_loaded?" and set it to true after I've processed all my inserts. But that's really gross... Ideas? Thanks!!

  • problems with retrieving data that was saved outside of a grails webflow

    - by callie16
    Hi, this is actually connected to an earlier question of mine here. Anyway, I have 3 domains that look like this: class A { ... static hasMany = [ b : B ] ... } class B { ... static belongsTo = [ a : A ] static hasMany = [ c : C ] ... } class C { ... static belongsTo = [ b : B ] ... } In my GSP page, I call an action in the Controller via a remote function in a javascript block (I'm using Dojo so I'm passing data to be saved this way... it's not a form per se so I use JSON for now to pass the data to the Controller). Let's say, I'm calling something like this: def someAction = { def jsonArr = [parse the JSON here] def tmpA = A.get(params.id) ... def tmpB = new B() b.someParam = jsonArr.someParam ... def tmpC = new C() tmpC.cParam = jsonArr.cParam tmpB.addToC(tmpC) tmpB.save(flush: true) //this may or may not be here but I'm adding it for the sake of completeness tmpA.addToB(tmpB) tmpA.save(flush: true) // NOTE: If I check here via println or whatnot, tmpA has a tmpB which has a tmpC... in other words, the data got saved. It's also in the DB. redirect(action: 'order' ...) } Then comes the fun part. Here's the webflow sample: def orderFlow = { ... someStateIShouldEndUpIn { on("next") { // or on previous... doesn't matter def anId = params.id def currA = A.get(anId) // this does NOT return a null value def testB = currA.b // this DOES return a null value }.to("somePage") ... } ... } Any ideas on why this happens? Moreover, when I dump the data of currA, b=null... instead of b=[] or b=[contents of tmpB]. Any help would be seriously appreciated... been at this for a couple of days now... Thanks!

  • Proper status codes for JSON responses to Ajax calls?

    - by anonymous coward
    My project is returning JSON to Ajax calls from the browser. I'm wondering what the proper status code is for sending back with responses to invalid (but successfully handled) data submissions. For example, jQuery has the following two particular callbacks when making Ajax requests: success: Fired when a 200/2xx status code is delivered along with the response. error: Fired when 4xx, 5xx, etc, status codes come back with the response. If a user attempts to create a new "Person" object, I send back a JSON representation of the newly created object upon success, thus giving javascript access to the necessary unique ID's for the new object, etc. This, of course, is sent with a 200 status code. If a user submits malformed or invalid data (say, an invalid/incomplete "name" field), I would like to send back the validation error messages via JSON. (I don't see why this would be a bad thing). My question is: in doing so, should I send a 200 status code, because I successfully handled their invalid data? Therefore, I'd be using the jQuery success callback, but simply check for errors... Or, should I use a 4xx status code, perhaps 'Bad Request', because the data they sent me is invalid? (and thus, use the error callback to do the necessary client-side notifications).

  • Dynamically add data stored in php to nested json

    - by HoGo
    I am trying to dynamicaly generate data in json for jQuery gantt chart. I know PHP but am totally green with JavaScript. I have read dozen of solutions on how dynamicaly add data to json, and tried few dozens of combinations and nothing. Here is the json format: var data = [{ name: "Sprint 0", desc: "Analysis", values: [{ from: "/Date(1320192000000)/", to: "/Date(1322401600000)/", label: "Requirement Gathering", customClass: "ganttRed" }] },{ name: " ", desc: "Scoping", values: [{ from: "/Date(1322611200000)/", to: "/Date(1323302400000)/", label: "Scoping", customClass: "ganttRed" }] }, <!-- Somoe more data--> }]; now I have all data in php db result. Here it goes: $rows=$db->fetchAllRows($result); $rowsNum=count($rows); And this is how I wanted to create json out of it: var data=''; <?php foreach ($rows as $row){ ?> data['name']="<?php echo $row['name'];?>"; data['desc']="<?php echo $row['desc'];?>"; data['values'] = {"from" : "/Date(<?php echo $row['from'];?>)/", "to" : "/Date(<?php echo $row['to'];?>)/", "label" : "<?php echo $row['label'];?>", "customClass" : "ganttOrange"}; } However this does not work. I have tried without loop and replacing php variables with plain text just to check, but it did not work either. Displays chart without added items. If I add new item by adding it to the list of values, it works. So there is no problem with the Gantt itself or paths. Based on all above I assume the problem is with adding plain data to json. Can anyone please help me to fix it?
