    - by Alfonso de la Osa
    Hi! I wrote this post Music and Mathematics, finding the Natural and the Pentatonic scales. Is a method to find the Natural scale. I want to discuss it and find if its true. This is the code of the reasoning in js. <script> var c = 12/7; var tot = 0; var scale = []; while(tot < (14 - c)){ tot += c; scale.push(Math.round(tot)); } if(scale.length == 8){ document.write(scale + " " + c + "<br />"); } </script>

  • Jquery CPU usage

    - by nharry
    I am using Jquery to make an image scroll across my page horizontally. The only problem is that it uses a serious amount of cpu usage. Up to 100% on a single core laptop in firefox. What could cause this??? Jquery <script> jQuery(document).ready(function() { $(".speech").animate({backgroundPosition: "-6000px 0px"}, 400000, null); }); </script> CSS .speech { /*position:fixed;*/ top:0; left:0px; height:400px; width:100%; z-index:-1; background:url(/images/speech.png) -300px -500px repeat-x; margin-right: auto; margin-left: auto; position: fixed; } HTML <div class="speech"></div>

  • Faking Fixed Position in IE6

    - by Andrew
    I have a site that utilizes a bottom fixed position masthead here: http://www.entheospartners.com/newsite/ This setup works great in all browsers except IE6, which doesn't support fixed positioning in the least, so here's what I've done: When an IE6 user comes to the page, I make the determination if scrolling is necessary using this bit of code: var windowHeight = $(window).height(); var totalHeight = windowHeight - 100; // where 100 is the sum of the top nav height + footer height var contentHeight; if($('#subpage-content-small').length) { // main content div for a three column layout contentHeight = $('#subpage-content-small').height(); }; if($('#subpage-content-wide').length) { // main content div for a two column layout contentHeight = $('#subpage-content-wide').height(); }; if(contentHeight > totalHeight) { $('#container-container').css({ 'overflow-y' : "scroll", 'height' : totalHeight }); }; ...which calculates everything correctly, puts the scrollbars where they need to be (flush right), and sets them to the appropriate height. The problem is that the scrollbars don't move the content. I can't say that I've ever seen anything quite like this before, so I'm hoping someone else on here has. Thanks in advance! PS - Obviously, this needs to be looked at in IE6 for troubleshooting, which I know will be as painful for you as it is for me.

  • Permission denied to access property 'toString'

    - by Anders
    I'm trying to find a generic way of getting the name of Constructors. My goal is to create a Convention over configuration framework for KnockoutJS My idea is to iterate over all objects in the window and when I find the contructor i'm looking for then I can use the index to get the name of the contructor The code sofar (function() { constructors = {}; window.findConstructorName = function(instance) { var constructor = instance.constructor; var name = constructors[constructor]; if(name !== undefined) { return name; } var traversed = []; var nestedFind = function(root) { if(typeof root == "function" || traversed[root]) { return } traversed[root] = true; for(var index in root) { if(root[index] == constructor) { return index; } var found = nestedFind(root[index]); if(found !== undefined) { return found; } } } name = nestedFind(window); constructors[constructor] = name; return name; } })(); var MyApp = {}; MyApp.Foo = function() { }; var instance = new MyApp.Foo(); console.log(findConstructorName(instance)); The problem is that I get a Permission denied to access property 'toString' Exception, and i cant even try catch so see which object is causing the problem Fiddle http://jsfiddle.net/4ZwaV/

  • How to parse (infinite) nested object notation?

    - by kyogron
    I am currently breaking my head about transforming this object hash: "food": { "healthy": { "fruits": ['apples', 'bananas', 'oranges'], "vegetables": ['salad', 'onions'] }, "unhealthy": { "fastFood": ['burgers', 'chicken', 'pizza'] } } to something like this: food:healthy:fruits:apples food:healthy:fruits:bananas food:healthy:fruits:oranges food:healthy:vegetables:salad food:healthy:vegetables:onions food:unhealthy:fastFood:burgers food:unhealthy:fastFood:chicken food:unhealthy:fastFood:pizza In theory it actually is just looping through the object while keeping track of the path and the end result. Unfortunately I do not know how I could loop down till I have done all nested. var path; var pointer; function loop(obj) { for (var propertyName in obj) { path = propertyName; pointer = obj[propertyName]; if (pointer typeof === 'object') { loop(pointer); } else { break; } } }; function parse(object) { var collection = []; }; There are two issues which play each out: If I use recurse programming it looses the state of the properties which are already parsed. If I do not use it I cannot parse infinite. Is there some idea how to handle this? Regards

  • JS: Why isn't this variable available to the other functions?

    - by Marius Jonsson
    Hello there, I've am trying to make a canvas animation: var context; var meter; var pin; function init() { var meter = new Image(); var pin = new Image(); var context = document.getElementById('canvas').getContext('2d'); meter.src = 'background.png'; pin.src = 'needle.png'; context.drawImage(meter,0,0); context.translate(275,297); context.save(); setTimeout(startup,500); } function startup() { var r=2; // set rpm here. var i=r*36-27; var angleInRadians = 3.14159265 * i/180; //converting degree to radian context.rotate(angleInRadians); //rotating by angle context.drawImage(pin,-250,-3); //adjusting pin center at meter center context.restore(); } You can see the script at http://www.kingoslo.com/instruments/ With firebug I get error saying that context is undefined, which I think is strange. Thanks. Kind regards, Marius

  • Jquery Bugs?? Long decimal number after two numbers multiply...

    - by Jerry
    Hi all I am working on a shopping site and I am trying to calculate the subtotal of products. I got my price from a array and quantity from getJSON response array. Two of them multiply comes to my subtotal. I can change the quantity and it will comes out different subtotal. However,when I change the quantity to certain number, the final subtotal is like 259.99999999994 or some long decimal number. I use console.log to check the $price and $qty. Both of them are in the correct format ex..299.99 and 6 quantity.I have no idea what happen. I would appreciate it if someone can help me about it. Here is my Jquery code. $(".price").each(function(index, price){ $price=$(this); //get the product id and the price shown on the page var id=$price.closest('tr').attr('id'); var indiPrice=$($price).html(); //take off $ indiPrice=indiPrice.substring(1) //make sure it is number format var aindiPrice=Number(indiPrice); //push into the array productIdPrice[id]=(aindiPrice); var url=update.php $.getJSON( url, {productId:tableId, //tableId is from the other jquery code which refers to qty:qty}, productId function(responseProduct){ $.each(responseProduct, function(productIndex, Qty){ //loop the return data if(productIdPrice[productIndex]){ //get the price from the previous array we create X Qty newSub=productIdPrice[productIndex]*Number(Qty); //productIdPrice[productIndex] are the price like 199.99 or 99.99 // Qty are Quantity like 9 or 10 or 3 sum+=newSub; newSub.toFixed(2); //try to solve the problem with toFixed but didn't work console.log("id: "+productIdPrice[productIndex]) console.log("Qty: "+Qty); console.log(newSub); **//newSub sometime become XXXX.96999999994** }; Thanks again!

  • Problems crossing the boundary between protected greasemonkey execution space and the unsafeWindow l

    - by Chilly
    Hi guys. Here is my problem: I've registered some callbacks into a Yahoo event driven webpage (betfair.com market views) and am trapping the betsPlaced events with a handler. So far so simple. Next stage is to get the event back into greasemonkey land, and while I know that from greasemoney space you can call unsafeWindow.stuff, there is no reverse operation (by design). So if I want to send the contents of the event over, say, a cometd queue, my carefully set up jquery, greasemonkey, YUI2, betfair environment fails by telling me that unsafeWindow processes cant call GM_ajax stuff. This is obviously safe and sane, but it basically stops me doing what I want to do. Has anyone tried doing this (ignore the cometd stuff, just general ajax calls) and succeeded? I've had a look at pages like this: http://wiki.greasespot.net/0.7.20080121.0%2B_compatibility but it doesnt appear to work for all the calls.

  • Web Audio API and mobile browsers

    - by Michael
    I've run into a problem while implementing sound and music into an HTML game that I'm building. I'm using the Web Audio API, loading all the sound files with XMLHttpRequests and decoding them into an AudioBufferSourceNode with AudioContext.prototype.decodeAudioData(). It looks something like this: var request = new XMLHttpRequest(); request.open("GET", "soundfile.ogg", true); request.responseType = "arraybuffer"; request.onload = function() { context.decodeAudioData(request.response) } request.send(); Everything plays fine, but on mobile the decodeAudioData takes an absurdly long time for the background music. I then tried using AudioContext.prototype.createMediaElementSource() to load the music from an HTML Audio object, since they support streaming and don't have to load the whole file into memory at once. It looked something like this: var audio = new Audio('soundfile.ogg'); var source = context.createMediaElementSource(audio); var mainVolume = context.createGain(); source.connect(mainVolume); mainVolume.connect(context.destination); This loads much faster, but the audio volume isn't affected by the gain node. Works fine on desktop, so I'm assuming this is a bug/limitation of mobile Chrome (testing on Android). Is there actually no good, well-performing way to handle sound on mobile browsers or am just I doing something stupid?

  • What does the MS Ajax Framework use location.hash for?

    - by DDaviesBrackett
    I've noticed that the MS ajax framework touches the action of the default form during Sys.Application.initialize, appending location.hash to it. This is interfering with other code in my app that expects different behaviour. What does the framework do with that? It refers to the values it puts on the hash as 'state', but how do I find out what it's communicating and from where?

  • jquery document.ready multiple declaration

    - by Hendry H.
    I realized that I can specify $(document).ready(function(){}); more than once. Suppose like this $(document).ready(function(){ var abc = "1122"; //do something.. }); $(document).ready(function(){ var abc = "def"; //do something.. }); Is this standard ? Those codes work on my FF (16.0.2). I just a little afraid that other browser may not. What actually happen ? How jQuery handle those code ? Thanks.

  • Auto save changed text in richtextbox to database

    - by user2519407
    I have created one simple note taking application in jquery & php. Current functionality is like when user clicks save button it sends a ajax request with complete data to update it in db(mysql). All works well. But now I want to auto save only changed text while user typing. I don't want to send entire text to server again and again in text change event. It should send only text which has changed. For Ex: This is saved text. When user continues typing. This is saved text. Unsaved text.. It should be able to send only "Unsaved text.." to server to update in db. How can i implement this in jquery & server side script.? Any Idea..?
