I'm trying to implement free drawing in my windows 8 app but I keep getting this error:
"0x800a01bd - JavaScript runtime error: Object doesn't support this action
File: fabric.js, Line: 12857, Column: 7"
Adding images to the canvas etc. all works as it does in the demos but in VS when I hovered over "fabric" in this code, fabric.Shadow is not shown as an option in the list:
setShadow: function(options) {
return this.set('shadow', new fabric.Shadow(options));
},
Does anyone know why this isn't working for me? I created a build of the api from www.fabricjs.com and included all modules. I've copied the code from the free drawing demo (http://fabricjs.com/freedrawing/) but no joy. I also tried removing any reference to creating a shadow as I don't plan on using that functionality but it still crashes. Thank you
Thank you! It's working for me now. I did have to change the JavaScript provided by the demo to make it work though. Just as a reference to anyone who may want to use it with Windows 8 in future, the jquery code needs to be made more strict for it to update the selectors.
Provided code:
var $ = function(id){return document.getElementById(id)};
var drawingModeEl = $('drawing-mode'),
drawingOptionsEl = $('drawing-mode-options'),
drawingColorEl = $('drawing-color'),
drawingShadowColorEl = $('drawing-shadow-color'),
drawingLineWidthEl = $('drawing-line-width'),
drawingShadowWidth = $('drawing-shadow-width'),
drawingShadowOffset = $('drawing-shadow-offset'),
clearEl = $('clear-canvas');
I did away with the above and just used the standard jquery selector $('#drawing-mode') each time I needed it. Then the events were provided as:
drawingModeEl.onclick = function() {}
drawingColorEl.onchange = function() {}
so I changed the above to:
$('#drawing-mode').on('click', function () {});
$('#drawing-color').change(function (){});
Now everything works as it does in the demo. Love this API, thank you!

I have a problem with my modal events. None of them I tested worked.
I'm using Bootstrap 3.3.6 and I tested my code in a jsfiddle and everything is working well there.
Here's my js :
$('#delete').on('show.bs.modal', function(e) {
var title = $(e.relatedTarget).data('title');
var id = $(e.relatedTarget).data('id');
document.getElementById('id').value = id;
document.getElementById('title').innerHTML = title;
});
I have no errors in my console, the modal shows up but the event isn't fired. I've tried show, shown and loaded.
Thank you for your help
Before asking this question, I haven't tested the .modal('show) method.
I got an error and after few checkups it's because I had two different versions of Jquery.
Problem solved after removing one.
Just started trying to create a menubar for my node webkit app, and I followed the instructions straight from the master Roger Wang himself...here:
https://github.com/rogerwang/node-webkit/wiki/Window-menu
Here is the code:
var gui = require('nw.gui');
var mb = new gui.Menu({type:"menubar"});
mb.createMacBuiltin("your-app-name");
gui.Window.get().menu = mb;
Works beautifully on mac, but makes the PC app not work. Any ideas now to solve it?
Thanks in advance.
I expect that createMacBuiltin isn't defined when you're running on non-Mac platforms. You should probably protect that code with an os-specific check, like this:
var gui = require('nw.gui');
var mb = new gui.Menu({type:"menubar"});
if (process.platform === "darwin") { // this should indicate you're on Mac OSX
mb.createMacBuiltin("your-app-name");
}
gui.Window.get().menu = mb;
This is assuming, of course, that the surrounding code is platform independent and you want it to run on all platforms.
I would like to perform a programmatic view transition.
Here is a code I've tried :
var v = registry.byId('myenergy-pane');
v.transitionTo("home-pane");
Here is another one
var v = registry.byId('myenergy-pane');
v.performTransition("home-pane",1,"slide",null);
None of them is working.
Thanks for your help.
The second code you provided should work, but that's considering the following facts:
The code is executed after the DOM is loaded and the views are parsed by the dojo/parser. The correct way to indicate that is by using dojo/ready, for example:
require(["dojo/ready"], function(ready) {
var v = registry.byId('myenergy-pane');
v.performTransition("home-pane", 1, "slide", null);
});
Both given IDs (myenergy-pane and home-pane) are related to a widget (not only a DOM node) and are both views (dojox/mobile/View or inheriting from).
Make sure you are loading dijit/registry and the registry module alias is actually mapped to the correct module.
I also made a JSFiddle to demonstrate that it should be working: http://jsfiddle.net/g00glen00b/3JMnC/
I am a complete novice with HTML5 and coding for that matter. I have been trying to get to grips with the web audio API. I want a sound to play at a click of a button. I used a tutorial posted on HTML5Rocks, but cannot get it to work. I have tried to use jfiddle to help me troubleshoot, but to no avail.
here is my code:
http://jsfiddle.net/ue8WP/
Try this:
function playsound()
{
var filepath='sounds/'+....+'.mp3'; //example
var audio = new Audio();
audio.src = filepath;
audio.controls = true;
audio.autoplay = true;
}
Here's a simplified version of your code that should work fine. You only need to load some other sample sound, since there is a problem with fetching the one you provided (not allowed by Access-Control-Allow-Origin).

I'm a complete newbie at Dojo, and Adobe AIR, which is my target. I'm
trying to put some panes into an AccordionContainer like so:
var mainview = dijit.byId("mainview");
var rand = randomString();
var widg = gtd_create_entry_widget(rand)
air.trace(mainview);
air.trace(widg);
mainview.addChild(widg);
"mainview" is my AccordionContainer, and gtd_create_entry_widget() is:
function gtd_create_entry_widget(id) {
var entry = new dijit.layout.ContentPane();
entry.attr("id",id);
entry.attr("title","title "+id);
return entry;
}
The pane shows up in the container, with the correct id and title, and
no errors, however, if I try to add another pane, the next one shows
up too, but I get the error:
TypeError: Result of expression '_7' [undefined] is not an object.
I get the same error if I run
var mainview = dijit.byId("mainview");
mainview.destroyDescendants();
and also, only one pane is destroyed at a time, and I understand this
method should destroy all the children.
I can include full project code if required.
Thanks a lot
Garry
I'm not exactly sure if this is going to fix your problem, but you're supposed to use dijit.layout.AccordianPane (http://www.dojotoolkit.org/api/dijit/layout/AccordionPane.html) with the AccordianContainer.
