donavon / ArrayContains.js
Created July 5, 2011 23:40
Does a JavaScript array contain a search element
// Array.contains
// compares searchElement to elements of the Array using strict equality
// (the same method used by the ===, or triple-equals, operator) and returns true or false
// Requires Array.indexOf. If not, see:
// https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/indexOf
// ex: [1,2,3].contains(2) returns true
if (!Array.prototype.contains) {
Array.prototype.contains = function (searchElement) {
return this.indexOf(searchElement) !== -1;

donavon / getThumbnailFromWebView.js
Last active March 22, 2016 06:17
`transformImageStream` is a WinJS (Windows 8) utility to transform an image stream. The sample code to get a snapshot from a WebView control requires Windows 8.1.
// Takes a snapshot of WebView control (Windows 8.1) and returns a thumbnail URL.
function getThumbnailFromWebView(webviewControl, width, height) {
return capturePreviewToBlobAsync(webviewControl).then(function (completeEvent) {
var blob = completeEvent.target.result;
var streamIn = blob.msDetachStream();
var Imaging = Windows.Graphics.Imaging;
var transform = new Imaging.BitmapTransform();
transform.scaledHeight = height;
transform.scaledWidth = width;
