Using jQuery plugins in Store Apps

Question

Hello!

I a trying to use jQuery plugin called CProgress, but I'm getting exception on line like ... ctx.drawImage ... 

Is there any difference between usual page and Windows Store app? Everything works well in IE.

Answer 1

There are a few contextual differences, but Windows Store apps and IE use the same underlying engine. What sort of exception are you getting and on what code? drawImage is supported and works in general.

Answer 2

Hello, Rob!!

Thank you for answering!

Error doesn't says much "0x80004005 - JavaScript runtime error: Unspecified error."

Code is very long, but I try to place a short:

 (function ( $ ) {
 	if (!$.ns) {
 		$.ns = {};
 	};

$.ns.cprogress = function ( el, options) {
var base = this;
// Access to jQuery and DOM 
base.$el = $(el);
base.el = el;
base.$el.data( "ns.cprogress" , base );

base.options = $.extend({}, $.ns.cprogress.defaultOptions, options);


base.methods = {
init: function () {


//Images
base.img1 = new Image();
base.img1.src = base.options.img1;

.......
.......
.......
.......


base.ctx.clearRect(0,0,base.width,base.height);
base.ctx.save();
base.ctx.drawImage(base.img1,0,0);

0x80004005 is just a generic failure, so it doesn't really tell us much.

The code you posted appears to be fine. Can you reproduce the problem with a cut down version of that or is it only when using the full project?

Oh, Rob! Seems that I was in panic!)

The exception was thrown just cause I'v choosed a wrong image folder.

Everything works well!
