When I include the custom test videoautoplay (https://github.com/Modernizr/Modernizr/blob/master/feature-detects/video/autoplay.js) the build throws the error 'define is undefined' (see screenshot).
Any idea how to fix this?
I believe you are trying to include a modernizr 3.0 test when the grunt-modernizr plugin is only compatible with modernizr 2.7.1. It's a bit confusing!
Work is being done in a different branch to make grunt-modernizr compatible with modernizr 3.0.
Here are the 2.7.1 feature detects: https://github.com/Modernizr/Modernizr/tree/v2.7.1/feature-detects
It looks like video-autoplay is not there, so you might need copy the detect from 3.0 and adapt it to work with 2.7.1 and include it as a custom test. Use this simple detect as a reference.
I had the same issue, and wrote a custom script that translates the new 'test' into the 2.8.3 format, hope it helps:
(function( ){
var timeout;
var waitTime = 200; // Too short will not work.
var elem = document.createElement('video');
var elemStyle = elem.style;
// skip the test if video itself, or the autoplay
// element on it isn't supported
if (!Modernizr.video || !('autoplay' in elem)) {
Modernizr.addTest('videoautoplay', false);
return;
}
elemStyle.position = 'absolute';
elemStyle.height = 0;
elemStyle.width = 0;
try {
if ( Modernizr.video.ogg ) {
elem.src = 'data:video/ogg;base64,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';

I've been trying to cycle through colors using a custom component.
<script>
AFRAME.registerComponent('floor-cycle', {
init: function () {
var sceneEl = document.querySelector('a-scene');
var floorEl = sceneEl.querySelector('#floor')
status = 1;
floorEl.addEventListener('click', function () {
if(status==1) {
floorEl.setAttribute('color', 'red'); status = 2
}
else if(status==2) {
floorEl.setAttribute('color', 'blue'); status = 3;
}
else if(status==3) {
floorEl.setAttribute('color', 'green'); status = 1
}
}
);
}
});
</script>
The component uses status to set the color attribute on click event, however this seems inefficient. Can this be implemented using an array rather than status?
demo - https://codepen.io/MannyMeadows/pen/GWzJRB
You can make an array ['red','green','blue'] and Cycle through it:
colors = ['red','green','blue'];
let i = 0;
floorEl.addEventListener('click',function(){
floorEl.setAttribute('material','color', colors[i]);
function add(){(i==colors.length-1) ? i = 0 : i++;}
add();
});
Seems better as the array is now dynamic, not sure how about the performance.

In react-native doc, it says to check UIExploreIntegrationTest. It seems that it requires some setup on Xcode as it uses Objective C code(*.m). I'm new on Obj-C test.. May I know how to set up the integration test on Xcode?
With some guesswork I was able to nail down a few steps to get integration tests running on iOS. However I'm still figuring out how to get Android integration tests working.
Go ahead and copy IntegrationTests.js from the RN github and make a new JS file called Tests.js
Place both of these files in the root of your project. Then change IntegrationTests.js by going down and changing all of their requires to just one require statement for the file you just created require('./Tests')
Here is a basic implementation of what your Tests.js file should look like:
'use strict';
var React = require('react');
var ReactNative = require('react-native');
var {
Text,
View,
} = ReactNative;
var { TestModule } = ReactNative.NativeModules;
var Tests = React.createClass({
shouldResolve: false,
shouldReject: false,
propTypes: {
RunSampleCall: React.PropTypes.bool
},
getInitialState() {
return {
done: false,
};
},
componentDidMount() {
if(this.props.TestName === "SomeTest"){
Promise.all([this.SomeTest()]).then(()=>
{
TestModule.markTestPassed(this.shouldResolve);
});
return;
}
},
async SomeTest(){
var one = 1;
var two = 2;
var three = one + two;
if(three === 3){
this.shouldResolve = true;
}else{
this.shouldResolve = false;
}
}
render() : ReactElement<any> {
return <View />;
}
});
Tests.displayName = 'Tests';
module.exports = Tests;
Here is a basic implementation of your Tests.m file (inside xcode)
#import <UIKit/UIKit.h>
#import <XCTest/XCTest.h>
#import <RCTTest/RCTTestRunner.h>
#import "RCTAssert.h"
#define RCT_TEST(name) \
- (void)test##name \
{ \
[_runner runTest:_cmd module:##name]; \
}
#interface IntegrationTests : XCTestCase
#end
#implementation IntegrationTests
{
RCTTestRunner *_runner;
}
- (void)setUp
{
_runner = RCTInitRunnerForApp(#"IntegrationTests", nil);
}
- (void)test_SomeTest
{
[_runner runTest:_cmd
module:#"Tests"
initialProps:#{#"TestName": #"SomeTest"}
configurationBlock:nil];
}
#end
Also you need to add RCTTest from node_modules/react-native/Libraries/RCTTest/RCTTest.xcodeproj to your libraries. then you need to drag the product libRCTTest.a of that project you added to Linked Frameworks and Libraries for your main target in the general tab.
^^ that path might be slightly incorrect
Then you need to edit your scheme and set an environment variable CI_USE_PACKAGER to 1
So if you do all those steps you should have a simple test run and pass. It should be fairly easy to expand after that. Sorry if my answer is slightly sloppy, let me know if you have any questions.
I'm writing a JS Widget using RequireJS. After finishing the widget I'm compiling it with r.js and Almond. All goes well - but I couldn't find an easy way to let the user use the widget without using RequireJS himself - as the widget code loads async (RequireJS uses AMD).
What I'm doing now is busy waiting for the widget code to load and using it only after detecting it has loaded. This is not very user-friendly.
Is there a way to let just do something like this?
var widget = new Widget();
instead of doing busy wait like:
count = 0;
function loadWidget() {
if (typeof Widget != 'undefined') {
var p1 = new Widget();
p1.render();
} else {
if (count > 10) {
console.log('Failed to load the Widget');
return false;
}
setTimeout(loadWidget, 50);
count++;
}
}
$(document).ready(function() {
loadWidget();
});
Thanks!
EDIT:
my build.js
({
name: './lib/almond.js',
out: './deploy/sdk.min.js',
baseUrl: '.',
optimize: 'uglify2',
mainConfigFile: 'sdk.js',
include: ['sdk'],
wrap: true
})
Code on the web page (assume no other script tags on page):
<script src="mywidget.js" data-main="scripts/sdk" id="mywidget"></script>
No sure if the 'data-main' is really required as the js is compiled.
You need to follow the instructions provided with Almond. To summarize the essential points what is in the doc there, what you need in your build config the following configuration:
wrap: {
startFile: 'path/to/start.frag',
endFile: 'path/to/end.frag'
}
And the start.frag should be:
(function (root, factory) {
if (typeof define === 'function' && define.amd) {
define([], factory);
} else {
root.Widget = factory();
}
}(this, function () {
and the end.frag:
return require('main');
}));
The end fragment calls require in its synchronous form, which is really synchronous in this case (and not the pseudo-synchronous sugar that can be used by RequrieJS itself).
I've tried this before. It works.
I try to print the content of the details tag in Chrome but I can't force it to open.
This is what I have in my print CSS :
details, details > * { display:block !important; }
But the content appear only if I open the details before printing the page.
Is there any way to force opening details by css print on chrome ?
Reasonable cross-browser solution with jQuery (not Opera)...adapted from https://www.tjvantoll.com/2012/06/15/detecting-print-requests-with-javascript/:
// Set up before/after handlers
var beforePrint = function() {
$("details").attr('open', '');
};
var afterPrint = function() {
$("details").removeAttr('open');
};
// Webkit
if (window.matchMedia) {
var mediaQueryList = window.matchMedia('print');
mediaQueryList.addListener(function(mql) {
if (mql.matches) {
beforePrint();
} else {
afterPrint();
}
});
}
// IE, Firefox
window.onbeforeprint = beforePrint;
window.onafterprint = afterPrint;
A simple solution in vanilla JavaScript which restores the state of opened/closed details tags after printing:
// open closed details elements for printing
window.addEventListener('beforeprint',() =>
{
const allDetails = document.body.querySelectorAll('details');
for(let i=0; i<allDetails.length; i++)
{
if(allDetails[i].open)
{
allDetails[i].dataset.open = '1';
}
else
{
allDetails[i].setAttribute('open', '');
}
}
});
// after printing close details elements not opened before
window.addEventListener('afterprint',() =>
{
const allDetails = document.body.querySelectorAll('details');
for(let i=0; i<allDetails.length; i++)
{
if(allDetails[i].dataset.open)
{
allDetails[i].dataset.open = '';
}
else
{
allDetails[i].removeAttribute('open');
}
}
});
I found the solution by forcing the opening details tag with BeforePrint and Afterprint
class App.Views.main extends backbone.View
el : "body"
events :
"click [data-auto-focus]":"autoFocus"
initialize : () ->
# Add conditional classname based on support
$('html').addClass( (if $.fn.details.support then 'details' else 'no-details'))
$('details').details()
if (window.matchMedia)
mediaQueryList = window.matchMedia('print')
mediaQueryList.addListener (mql) =>
if (mql.matches)
#beforePrint()
else
#afterPrint()
window.onbeforeprint = => #beforePrint
window.onafterprint = => #afterPrint
render : () ->
openedDetailsBeforePrint : null
beforePrint : () ->
console.log "before print"
#openedDetailsBeforePrint = #$el.find('details[open], details.open')
if ($('html').hasClass('no-details')) then #$el.find('details').addClass("open") else #$el.find('details').attr("open", "")
afterPrint : () ->
console.log "after print"
#$el.find('details').removeClass(".open").removeAttr("open")
if ($('html').hasClass('no-details')) then #openedDetailsBeforePrint.addClass("open") else #openedDetailsBeforePrint.attr("open", "")
autoFocus : (e) ->
$element = if (e.currentTarget) then $(e.currentTarget) else $(e.srcElement)
return $($element.attr "data-auto-focus").focus()
Based on the answers from Christopher and Benjamin, I've created the following code:
window.matchMedia("print").addEventListener("change", evt => {
if (evt.matches) {
elms = document.body.querySelectorAll("details:not([open])");
for (e of elms) {
e.setAttribute("open", "");
e.dataset.wasclosed = "";
}
} else {
elms = document.body.querySelectorAll("details[data-wasclosed]");
for (e of elms) {
e.removeAttribute("open");
delete e.dataset.wasclosed;
}
}
})
Features:
Restores state after the print command so that details that were already open, stay open.
Minimize DOM manipulation by only altering details that are closed.
Support DevTools print emulation by using the print media query instead of the print event handler.
For this specific case (which I see today, but it takes time on StackOverflow), I think the best solution to this is add in CSS the details tag to the list of #media print, something like:
#media print {
…
details, details > * { display:block !important; }
}
A simple method in jQuery: (updated)
var mediaQueryList = window.matchMedia('print');
mediaQueryList.addListener( printTest );
function printTest(mql) {
dt = $( 'details' )
if (mql.matches) {
dt.each( function( index ){
b = $(this).attr('open');
if ( !b ){
$(this).attr('open','');
$(this).attr('print','');
}
});
} else {
dt.each( function( index ){
b = $(this).attr('print');
if ( !b ){
$(this).removeAttr('open');
$(this).removeAttr('print');
}
});
}
}
This printTest method verify if matches.
matches: open closed details elements and add an attribute print to close after.
!matches: close details elements with print attribute (and remove this attributes: open and print)
Looks more about this in JSFiddle
Here's a short answer in plain vanilla JavaScript. This just loops through all details tags, opens them all when printing, then closes them all after printing:
// Open all details tags when printing.
window.addEventListener( 'beforeprint', () => {
[].forEach.call( document.querySelectorAll( 'details' ), el => el.setAttribute( 'open', '' ) )
} )
// Close all details tags after printing.
window.addEventListener( 'afterprint', () => {
[].forEach.call( document.querySelectorAll( 'details' ), el => el.removeAttribute( 'open' ) )
} )

console.log("Error");
} else {
page.switchToFrame("thenameoftheiframe");
console.log(page.content);
phantom.exit();
}
});
It produces only the source code of the main page. Any idea ?
Notice that the iframe domain is different from the main page domain.
Please give this a try I believe it may be an async issues meaning the iframe is not present when trying to access it. I received the below snippet from another post.
var page = require('webpage').create(),
testindex = 0,
loadInProgress = false;
page.onConsoleMessage = function(msg) {
console.log(msg);
};
page.onLoadStarted = function() {
loadInProgress = true;
console.log("load started");
};
page.onLoadFinished = function() {
loadInProgress = false;
console.log("load finished");
};
/*
page.onNavigationRequested = function(url, type, willNavigate, main) {
console.log('Trying to navigate to: ' + url);
console.log('Caused by: ' + type);
console.log('Will actually navigate: ' + willNavigate);
console.log('Sent from the page\'s main frame: ' + main);
};
*/
/*
The steps array represents a finite set of steps in order to perform the unit test
*/
var steps = [
function() {
//Load Login Page
page.open("https://www.yourpage.com");
},
function() {
//access your iframe here
page.evaluate(function() {
});
},
function() {
//any other step you want
page.evaluate(function() {
});
},
function() {
// Output content of page to stdout after form has been submitted
page.evaluate(function() {
//console.log(document.querySelectorAll('html')[0].outerHTML);
});
//render a test image to see if login passed
page.render('test.png');
}
];
interval = setInterval(function() {
if (!loadInProgress && typeof steps[testindex] === "function") {
console.log("step " + (testindex + 1));
steps[testindex]();
testindex++;
}
if (typeof steps[testindex] !== "function") {
console.log("test complete!");
phantom.exit();
}
}, 50);
replace
console.log(page.content);
with
console.log(page.frameContent);
Should return the contents of the frame phantomjs switched to.
If the iframe is from another domain you may need to add the --web-security=no option like this:
phantomjs --web-security=no myscript.js
As an additional information, what xMythicx said could be true. Some iframes are rendered via Javascript after page finishes loading. If the iframe contents are empty, then you will need to wait for all resources to finish loading, before you start grabbing stuff from the page. But this is another issue, if you need an answer on this, I suggest you ask a new question about it, and I will answer there.
Had the same problem for iframes and
phantomjs --web-security=no
helped in my case :]
