rjcorwin / backbone-models-for-couchdb-boiler-plate.js

Last active December 18, 2015 03:19

The bare minimum you must do to get Backbone.js Models to work with CouchDB.

	var SomeModelClass = Backbone.Model.extend({

	idAttribute: "_id",

	url: function() {
	if (_.has(this, 'id')) {
	var url = (_.has(this.toJSON(), '_rev'))
	? this.server + '/' + this.db + '/' + this.id + '?rev=' + this.get('_rev') // For UPDATE and DELETE
	: this.server + '/' + this.db + '/' + this.id // For READ
	}

rjcorwin / open-pdf-from-pouchdb.js

Created July 26, 2013 20:28

Load a PDF from PouchDB using the PDF.js Viewer. This code would go somewhere around line 2930 in web/viewer.js replacing the code that opens the PDF for Firefox and non B2G browsers. Example (note the parameters): http://test.local:5984/mount/_design/app/PDF-JS-Pouch-Viewer/web/viewer.html?db=testfiles&docId=helloworld&file=helloworld.pdf


	if(params.db && params.docId && params.file) {
	Pouch(params.db, function(err, db) {
	db.getAttachment(params.docId, params.file, function(err, res) {
	var file = window.URL.createObjectURL(res)

	//#if (FIREFOX \|\| MOZCENTRAL)
	//if (FirefoxCom.requestSync('getLoadingType') == 'passive') {
	// PDFView.setTitleUsingUrl(file);
	// PDFView.initPassiveLoading();

rjcorwin / open-pdf-with-width-of-screen.js

Last active December 20, 2015 07:19

From pdf.js/examples/helloworld/hello.js, modify it to open display the page specified at the width of browser. We do this by looking at the width of the PDF's page and the width of the window and then setting the scale of the page's viewport accordingly (see line 5).

	PDFJS.getDocument(url).then(function(pdf) {
	// Using promise to fetch the page
	pdf.getPage(1).then(function(page) {
	// Scale the PDF to the width of the window
	var scale = window.innerWidth / page.view[2]
	var viewport = page.getViewport(scale);

	//
	// Prepare canvas using PDF page dimensions
	//

rjcorwin / vars-assigned-this-act-like-pointers.js

Created July 30, 2013 20:56

A variable with a "this" assigned to it will act like a pointer in Javascript.

	var x = {
	value: 1,
	change: function() {
	var that = this
	that.value++
	var foo = 1
	var bar = foo
	bar++
	alert(foo) // alerts 1
	}

rjcorwin / parallax-background-scroll-using-jquery.js

Created August 18, 2013 07:13

Dead simple parallax scroll an element's background using jQuery. Inspired by http://parascroll.wwwtyro.net/

	window.onscroll = function() {
	var speed = 3.0;
	$("#some-container").css("background-position",(window.pageXOffset / speed) + "px " + (window.pageYOffset / speed) + "px");
	// Scroll the background faster instead of slower
	// $("#some-container").css("background-position",(-window.pageXOffset / speed) + "px " + (-window.pageYOffset / speed) + "px");
	}
