Format percentages in AngularJS
// In app.js or main.js or whatever:
// var myApp = angular.module('askchisne', ['ngSanitize', 'ngAnimate', 'ui.bootstrap', 'ui.bootstrap.tpls']);
// This filter makes the assumption that the input will be in decimal form (i.e. 17% is 0.17).
myApp.filter('percentage', ['$filter', function ($filter) {
return function (input, decimals) {
return $filter('number')(input * 100, decimals) + '%';
};
}]);

good APIs for mashups

This list has been superseded by Public APIs. Check there for APIs with Auth: No, HTTPS and CORS Yes.


List of data APIs that require no server-side auth or private credentials, and are thus good for small browser-only JS projects.

Here's another chaining example on using q.js. This doesn't have any error handling, as I just want to demonstrate the chaining concept. Please read the comments carefully, as I start out with a non-q example, to show the order of flow. Please post comments if there's anything that isn't clear and I'll try to revise it as needed.

/*===========
We want to call these three functions in sequence, one after the other:
First we want to call one, which initiates an ajax call. Once that
ajax call is complete, we want to call two. Once two's ajax call is
complete, we want to call three.
BUT, we don't want to just call our three functions in sequence, as this quick

Support routine for adding W3C user timing events to a site. Includes some basic polyfill support for browsers that don't support user timing or navigation timing (though the start time for non-navigation timing support could be improved with IE < 9 to use IE's custom start event).
// Support routines for automatically reporting user timing for common analytics platforms
// Currently supports Google Analytics, Boomerang and SOASTA mPulse
// In the case of boomerang, you will need to map the event names you want reported
// to timer names (for mPulse these need to be custom0, custom1, etc) using a global variable:
// rumMapping = {'aft': 'custom0'};

var wtt = function(n, t, b) {
