  • current transform being applied by canvas

    - by Allain Lalonde
    How can I determine the current transform that's being applied by an html5 canvas. It seems that it only supports two methods for dealing with transforms "transform", "setTransform" but I can't seem to discover the results of applying the transforms. Short of tracking them all myself and duplicating the the matrix mathematics that it must be doing natively, how can I figure out the current transform?

  • Globally disable Ext JS Animations

    - by ifwdev
    I'm testing an intranet web app in the iPad but the animations to open "windows" and show message boxes are horribly slow. I've tried setting the global Ext.enableFx to false, and confirmed that flag is still false after page load in Firebug. The animations are still occurring though so I must be doing something wrong. Thanks...

  • How to properly pass address to google geocoding service

    - by clinisbut
    I'm getting some problems trying Google Geocoding service when using special characters like "º" or letters with accents. Whenever I try something like: "barcelona, nº 10" I get 0 results. But trying: "barcelona n 10" I get results... I suspect is something related with encoding. I tried this: geocoder.geocode({'address': encodeURI( $('#direction').val() )}, function(){} ); But didn't help. Any Idea?

My folder structures is this. root path = flipbooks subfolders under flipbooks are books and clients in subfolder books I have and .net page title tablet. the tablet code behind checks the bookid of client and render a the tablet page with images in a flipbook fashion. because we have over 15000 records and flipbooks already created and stored in the database. I don't move the client folder under the books subfolders. I need the code below to get to the client subfolder in the query string and help to change this would be helpful. The result now is http://www.somewebsite.com/books/client/images/someimage1.jpg[^] I need the results to be http://www.somewebsite.com/client/images/someimage1.jpg[^]. I tried moving the tablet.aspx file to the root flipbooks and it works but i have provide a user name and password each time. This need to be access by the public and my root is protected. Don't want to have to change permission.

  • Webkit browser jQuery transformations/transitions not working with jSplitSlider

    - by user3689793
    I am helping to build a site and i'm having an issue with the functionality of an add-in called jsplitslider when running it in chrome. Right now, when I navigate between the slides, the div's get stuck on top of each other and never clear the webkit transformations/animations: <div class="sl-content-slice" style="transition: all 800ms ease-in-out; -webkit-transition: all 800ms ease-in-out;"> I think the problem is due to timing of the functions, but I can't seem to figure out where I would need to add a setTimeout(). I only think this because I exhausted a lot of the other options like display: inline-block, notransitions css, etc. I'm desperate to figure out how to make this work in chrome. It works in FF and IE(surprisingly enough). I'm not great at webcoding, so any help will be appreciated! The code on the site isn't minimized. Here is the jQuery where I think the problem lies: var cssStyle = config.orientation === 'horizontal' ? { marginTop : -this.size.height / 2 } : { marginLeft : -this.size.width / 2 }, // default slide's slices style resetStyle = { 'transform' : 'translate(0%,0%) rotate(0deg) scale(1)', opacity : 1 }, // slice1 style slice1Style = config.orientation === 'horizontal' ? { 'transform' : 'translateY(-' + this.options.translateFactor + '%) rotate(' + config.slice1angle + 'deg) scale(' + config.slice1scale + ')' } : { 'transform' : 'translateX(-' + this.options.translateFactor + '%) rotate(' + config.slice1angle + 'deg) scale(' + config.slice1scale + ')' }, // slice2 style slice2Style = config.orientation === 'horizontal' ? { 'transform' : 'translateY(' + this.options.translateFactor + '%) rotate(' + config.slice2angle + 'deg) scale(' + config.slice2scale + ')' } : { 'transform' : 'translateX(' + this.options.translateFactor + '%) rotate(' + config.slice2angle + 'deg) scale(' + config.slice2scale + ')' }; if( this.options.optOpacity ) { slice1Style.opacity = 0; slice2Style.opacity = 0; } // we are adding the classes sl-trans-elems and sl-trans-back-elems to the slide that is either coming "next" // or going "prev" according to the direction. // the idea is to make it more interesting by giving some animations to the respective slide's elements //( dir === 'next' ) ? $nextSlide.addClass( 'sl-trans-elems' ) : $currentSlide.addClass( 'sl-trans-back-elems' ); $currentSlide.removeClass( 'sl-trans-elems' ); var transitionProp = { 'transition' : 'all ' + this.options.speed + 'ms ease-in-out' }; // add the 2 slices and animate them $movingSlide.css( 'z-index', this.slidesCount ) .find( 'div.sl-content-wrapper' ) .wrap( $( '<div class="sl-content-slice" />' ).css( transitionProp ) ) .parent() .cond( dir === 'prev', function() { var slice = this; this.css( slice1Style ); setTimeout( function() { slice.css( resetStyle ); }, 150 ); }, function() { var slice = this; setTimeout( function() { slice.css( slice1Style ); }, 150 ); } ) .clone() .appendTo( $movingSlide ) .cond( dir === 'prev', function() { var slice = this; this.css( slice2Style ); setTimeout( function() { $currentSlide.addClass( 'sl-trans-back-elems' ); if( self.support ) { slice.css( resetStyle ).on( self.transEndEventName, function() { self._onEndNavigate( slice, $currentSlide, dir ); } ); } else { self._onEndNavigate( slice, $currentSlide, dir ); } }, 150 ); }, function() { var slice = this; setTimeout( function() { $nextSlide.addClass( 'sl-trans-elems' ); if( self.support ) { slice.css( slice2Style ).on( self.transEndEventName, function() { self._onEndNavigate( slice, $currentSlide, dir ); } ); } else { self._onEndNavigate( slice, $currentSlide, dir ); } }, 150 ); } ) .find( 'div.sl-content-wrapper' ) .css( cssStyle ); $nextSlide.show(); }, _validateValues : function( config ) { // OK, so we are restricting the angles and scale values here. // This is to avoid the slices wrong sides to be shown. // you can adjust these values as you wish but make sure you also ajust the // paddings of the slides and also the options.translateFactor value and scale data attrs if( config.slice1angle > this.options.maxAngle || config.slice1angle < -this.options.maxAngle ) { config.slice1angle = this.options.maxAngle; } if( config.slice2angle > this.options.maxAngle || config.slice2angle < -this.options.maxAngle ) { config.slice2angle = this.options.maxAngle; } if( config.slice1scale > this.options.maxScale || config.slice1scale <= 0 ) { config.slice1scale = this.options.maxScale; } if( config.slice2scale > this.options.maxScale || config.slice2scale <= 0 ) { config.slice2scale = this.options.maxScale; } if( config.orientation !== 'vertical' && config.orientation !== 'horizontal' ) { config.orientation = 'horizontal' } }, _onEndNavigate : function( $slice, $oldSlide, dir ) { // reset previous slide's style after next slide is shown var $slide = $slice.parent(), removeClasses = 'sl-trans-elems sl-trans-back-elems'; // remove second slide's slice $slice.remove(); // unwrap.. $slide.css( 'z-index', 10 ) .find( 'div.sl-content-wrapper' ) .unwrap(); // hide previous current slide $oldSlide.hide().removeClass( removeClasses ); $slide.removeClass( removeClasses ); // now we can navigate again.. this.isAnimating = false; this.options.onAfterChange( $slide, this.current ); }, Sorry if I missed any conventions when posting, this is my first S.O. post. Thanks in advance for any help.

  • KnockoutJS showing a sorted list by item category

    - by Darksbane
    I just started learning knockout this week and everything has gone well except for this one issue. I have a list of items that I sort multiple ways but one of the ways I want to sort needs to have a different display than the standard list. As an example lets say I have this code var BetterListModel = function () { var self = this; food = [ { "name":"Apple", "quantity":"3", "category":"Fruit", "cost":"$1", },{ "name":"Ice Cream", "quantity":"1", "category":"Dairy", "cost":"$6", },{ "name":"Pear", "quantity":"2", "category":"Fruit", "cost":"$2", },{ "name":"Beef", "quantity":"1", "category":"Meat", "cost":"$3", },{ "name":"Milk", "quantity":"5", "category":"Dairy", "cost":"$4", }]; self.allItems = ko.observableArray(food); // Initial items // Initial sort self.sortMe = ko.observable("name"); ko.utils.compareItems = function (l, r) { if (self.sortMe() =="cost"){ return l.cost > r.cost ? 1 : -1 } else if (self.sortMe() =="category"){ return l.category > r.category ? 1 : -1 } else if (self.sortMe() =="quantity"){ return l.quantity > r.quantity ? 1 : -1 }else { return l.name > r.name ? 1 : -1 } }; }; ko.applyBindings(new BetterListModel()); and the HTML <p>Your values:</p> <ul class="deckContents" data-bind="foreach:allItems().sort(ko.utils.compareItems)"> <li><div style="width:100%"><div class="left" style="width:30px" data-bind="text:quantity"></div><div class="left fixedWidth" data-bind="text:name"></div> <div class="left fixedWidth" data-bind="text:cost"></div> <div class="left fixedWidth" data-bind="text:category"></div><div style="clear:both"></div></div></li> </ul> <select data-bind="value:sortMe"> <option selected="selected" value="name">Name</option> <option value="cost">Cost</option> <option value="category">Category</option> <option value="quantity">Quantity</option> </select> </div> So I can sort these just fine by any field I might sort them by name and it will display something like this 3 Apple $1 Fruit 1 Beef $3 Meat 1 Ice Cream $6 Dairy 5 Milk $4 Dairy 2 Pear $2 Fruit Here is a fiddle of what I have so far http://jsfiddle.net/Darksbane/X7KvB/ This display is fine for all the sorts except the category sort. What I want is when I sort them by category to display it like this Fruit 3 Apple $1 Fruit 2 Pear $2 Fruit Meat 1 Beef $3 Meat Dairy 1 Ice Cream $6 Dairy 5 Milk $4 Dairy Does anyone have any idea how I might be able to display this so differently for that one sort?

  • Pre-formatting text to prevent reflowing

    - by mattjn
    I've written a fairly simple script that will take elements (in this case, <p> elements are the main concern) and type their contents out like a typewriter, one by one. The problem is that as it types, when it reaches the edge of the container mid-word, it reflows the text and jumps to the next line (like word wrap in any text editor). This is, of course, expected behavior; however, I would like to pre-format the text so that this does not happen. I figure that inserting <br> before the word that will wrap would be the best solution, but I'm not quite sure what the best way to go about doing that is that supports all font sizes and container widths, while also keeping any HTML tags intact. I figure something involving a hidden <span> element, adding text to it gradually and checking its width against the container width might be on the right track, but I'm not quite sure how to actually put this together. Any help or suggestions on better methods would be appreciated.

  • In Node.js, how can I load my modules once and then use them throughout the app?

    - by TIMEX
    I want to create one global module file, and then have all my files require that global module file. Inside that file, I would load all the modules once and export a dictionary of loaded modules. How can I do that? I actually tried creating this file...and every time I require('global_modules'), all the modules kept reloading. It's O(n). I want the file to be something like this (but it doesn't work): //global_modules.js - only load these one time var modules = { account_controller: '/account/controller.js', account_middleware: '/account/middleware.js', products_controller: '/products/controller.js', ... } exports.modules = modules;

  • Regular Expressions - Match all alphanumeric characters except individual numbers

    - by imaginonic
    I would like to create a RegEx to match only english alphanumeric characters but ignore (or discard) isolated numbers in Ruby (and if possible in JS too). Examples: 1) I would like the following to be matched: 4chan 9gag test91323432 asf5asdfaf35edfdfad afafaffe But not: 92342424 343424 34432 and so on.. The above is exactly what I would want. 2) However, I would be really thankful if someone could also include French letters like: é ë ê (These are just few examples of many) 1) is my priority, it's totally okay if 2) is impossible or difficult to implement. Sorry, my regex skills aren't that great (hence this question!) Thank you.

  • Backbone View: Inherit and extend events from parent

    - by brent
    Backbone's documentation states: The events property may also be defined as a function that returns an events hash, to make it easier to programmatically define your events, as well as inherit them from parent views. How do you inherit a parent's view events and extend them? Parent View var ParentView = Backbone.View.extend({ events: { 'click': 'onclick' } }); Child View var ChildView = ParentView.extend({ events: function(){ ???? } });

    What are cross-platform and cross browser and license free/Open source framework to create Touch/Multitouch based Web apps/site using HTML/CSS/JS, for mobile devices, specially for latest versions of Android, Blackberry, Windows 7, iphone and ipad available? For desktop websites I'm a jQuery lover. I know Sencha but it's not free I think. I know jQtouch but it's only for iPhone and I also know jquery mobile but I'm not cofirm, is it as powerful as Sencha? It's not necessarily for me to go with jquery mobile, if there are another better framework available than this I want to make compatible with Android, Blackberry, Windows 7 also. not only for iphone and ipad.

  • Override tablesorter CSS

    - by user1712810
    I am using jquery tablesorter. When the page loads, I have a code to highlight the background color of certain rows in the table. Since tablesorter is used I guess it overrides the css and not allowing to change the background color of the rows. This is the code. This function automatically loads when the page gets loaded. I removed table-sorter to the table and tried this. It works. I have to get it to work with the table-sorter applied. $(document).ready(function() { var row, len, results; row = 0; results = []; while (row < len) { if ($("#tab1 #example_"+row+"chkbx").is(":checked")) { $("#tab1 #example_" + row).css("background-color", "#c6b79f"); } row++; } return results; });

  • How to remove dangerous characters(ie script tags)?

    - by chobo2
    I am wondering is there any sort of C# class or 3rd party library that removes dangerous characters such as script tags? I know you can use regex but I also know people can write their script tags so many ways that you can fool the regex into thinking it is OK. I also heard that HTML Agility Pack is good so I am wondering is there any script removal class made for it?

  • How can I restore the order of an (incomplete) select list to its original order?

    - by Rob
    I have two Select lists, between which you can move selected options. You can also move options up and down in the right list. When I move options back over to the left list, I would like them to retain their original position in the list order, even if the list is missing some original options. This is solely for the purpose of making the list more convenient for the user. I am currently defining an array with the original Select list onload. What would be the best way to implement this?

  • Backbone: Easiest way to maintain reference to 'this' for a Model inside callbacks

Any ideas? Thanks.

  • Alter Regular Expression to Return 2 Values Instead of 3 from userAgent String

    I've taken a regular expression from jQuery to detect if a browser's engine is WebKit and gets it's version number, it returns 3 values extracted from the userAgent string: webkit/….…, webkit and ….… [“….…” being the version number]. I would like the regular expression to return just 2 values: webkit and ….…. I'm rubbish at regular expressions, so please can you give an explanation of the expression with your answer. The regular expression I'm currently working with and wish to improve is: /(webkit)[\/]([\w.]+)/. I appreciate all your help, thanks in advance!

  • Need some help synch'ing outer loop counter with dialog.onconfirm()

    - by Chris Barnhill
    I am writing a game for Facebook. IN the following code, I have a problem. I have a for loop executing, and in that loop, I call a dialog and implement 'onconfirm' for the dialog. The problem is that I need to access th e loop counter inside of the onconfirm function. But because the onconfirm is called outside of the scope of the for loop, the counter value is no longer valid because it's been incremented. I need some way to pass the counter value to the dialog onconfirm as it was at the time the dialog was displayed, not after the loop has finished. Or maybe someone has a better solution. Any help would be appreciated. Thanks. function unloadCargo() { //debugger; var actionPrompt = document.getElementById('action-prompt'); actionPrompt.setTextValue('Unloading cargo...'); var ajax = new Ajax(); ajax.responseType = Ajax.JSON; ajax.ondone = function(data) { debugger; if(data.unloadableCargo.length == 0) { loadCargo(); } else { //console.log('unloadable cargo='+dump(data.unloadableCargo)); var i = 0; var j = 0; var ucCount = data.unloadableCargo.length; for(i = 0; i < ucCount; i++) { cargoDialog = new Dialog(); cargoDialog.showChoice('Unload Cargo', 'Unload ' + data.unloadableCargo[i].goods_name + ' at ' + data.unloadableCargo[i].city_name + ' for ' + data.unloadableCargo[i].payoff + 'M euros?'); cargoDialog.onconfirm = function() { //console.log('unloadable cargo onconfirm='+dump(data.unloadableCargo)); var ajax = new Ajax(); var param = {"city_id": data.unloadableCargo[i].city_id, "goods_id": data.unloadableCargo[i].goods_id, "payoff": data.unloadableCargo[i].payoff}; ajax.ondone = function(demandData) { var demands = document.getElementById('demands'); var innerXhtml = '<span>'; for(var j = 0; j < demandData.demands.length; j++) { innerXhtml = innerXhtml + ' <div class="demand-item"><div class="demand-city">' + demandData.demands[j].city + '</div><div class="demand-pay">' + demandData.demands[j].cost + '</div><div class="demand-goods">' + demandData.demands[j].goods + '</div></div>'; } innerXtml = innerXhtml + ' </span>'; demands.setInnerXHTML(innerXhtml); // update balance loadCargo(); } ajax.post(baseURL + "/turn/do-unload-cargo", param); } cargoDialog.oncancel = function() { loadCargo(); } } //loadCargo(); } } ajax.post(baseURL + '/turn/unload-cargo'); }

  • CakePHP: Ajax view problem (nothing in the view showing)

    - by Adim
    I created a function in my controller called addToPlaylist($songName). I wanted to add these song names to an array and then a session variable using an Ajax call. The first time i did this i got an error saying i do not have a template file to display in the chosen div ("add_to_playlist.ctp was missing"). I created this file and everything seemed to be working correctly. Basically I went to bed woke up and it is broken (it is possible I changed something before I went to bed). The problem now is that it does not show anything when i click the ajax link. when i click on the ajax link it seems to call the function but nothing displays in the view (except debug info) even when i delete the view (add_to_playlist.ctp) i get no errors, I just see debug info now.
