When I use google's YTPlayer to display a video with cc_load_policy=1, and if the video in question has just a English (auto-generated) subtitle, captions still don't appear for me - shouldn't the English (auto-generated) one still be displayed in such a case?
I've tried setting the cc_lang_pref=en as well as the hl=en parameters but to no avail.
The cc_load_policy=1 parameter does work well with videos that do have an English subtitle, so I don't think the problem has anything to with code per se.
Is there perhaps a special language code for English (auto-generated) that I should be using instead?
new YT.Player("ytplayer_placeholder", {
width: "100%",
videoId: "4Uzbpj1UCEY",
playerVars: {cc_load_policy: 1},
events: {
'onReady': player_ready,
'onStateChange': schedule_buffering,
'onError': error_handler
}
});
The sample code above includes the youtube videoid that has such a problem.
It should have displayed the video with the English (auto-generated) captions but nothing appears. I can manually click the CC button to get the captions to appear though, but I need that to happen automatically.
There is no official or documented way to force auto-generated captions in embedded videos. However there is a solution with the setOption method which works now, but there is no guarantee it will work in the future as this is a non documented call of the method:
const onApiChange = _ => {
if (typeof player.setOption === 'function') {
player.setOption('captions', 'track', {languageCode: 'en'}) // undocumented call
}
}
function onYouTubePlayerAPIReady() {
player = new YT.Player('player', {
height: '360',
width: '640',
videoId: '4Uzbpj1UCEY',
playerVars: {
cc_load_policy: 1
},
events: {
onApiChange
}
})
}
Working jsFiddle is here.
You have to wait for an onApiChange event before using the setOption function. (See: https://developers.google.com/youtube/iframe_api_reference#Events) According to the docs only the 'fontSize' and the 'reload' parameters are supported. However, changing the captions track works too and it turns ON the captions as a side-effect. I tried only the 'en' languageCode, of course this will change to the normal english captions track if there is one available, but will display the auto-generated english captions in the absence of a predefined track.
(You can also query the active captions track with the getOption method, but it will return nothing if the auto-generated captions are used.)
so in the back of the 'discover meteor' book they explain how to do page transitions. i've got it working, however it causes problems with the loading of javascript functions and variables on other pages that its animating into. it seems they're not ready or simply don't exist at the time the page is routed.
Template.layout.onRendered(function() {
this.find('.pos-rel')._uihooks = {
insertElement: function(node, next) {
$(node).hide().insertBefore(next)
.delay(200)
.velocity("transition.slideUpIn", 1000)
},
removeElement: function(node) {
$(node).velocity({
opacity: 0,
},
{
duration: 100,
complete: function() {
$(this).remove();
}
});
}
}
});
if i remove the above code then all my javascript variables and functions work correctly. does anyone have another working solution to page transitions using velocity.js ? i did find this one but its a year old and i couldn't get it to work at all, it just makes the content where '{> yield}' is go blank :(
Just a note for asking questions on stack overflow: "causes problems with the loading of javascript functions and variables" is pretty vague. Its best to give more specifics.
But anyways, you said here that you're using isotope to render items in a grid. I'm assuming you're calling $elements.isotope() within a Template[name].onRendered callback.
This is probably the issue because its trying to compute and rearrange into a grid the elements while they're hidden. Using display: none actually removed the elements, thus isotope can't compute the sizes, etc. for the layout. Try this:
insertElement: function(node, next) {
$(node).css("opacity", 0).insertBefore(next)
.delay(200)
.velocity("transition.slideUpIn", {duration:1000, display:null})
},
opacity: 0 should do what you're looking for. It will make them transparent without removing them from the transition.slideUpIn should animate opacity so you're good there.
Also, velocity transitions mess with the display property. Setting display: null in the animation options prevents it from setting the display to block or whatever it wants to do. This may or may not be necessary, but I pretty much always use it.
You could use:
onAfterAction
onBeforeAction
. The solution should be something like this:
animateContentOut = function() {
$('#content').css('display', 'none');
this.next();
}
fadeContentIn = function() {
$('#content').velocity('transition.fadeIn',1000);
}
Router.onBeforeAction(animateContentOut)
Router.onAfterAction(fadeContentIn)
and if a link is underlined, i want it to get rid of the underline on hover. If a link has no underline, i want it to get one on hover.
Is there a smart way to do this with SASS rather than hard coding it for every link?
As others have stated, to do this within CSS or SASS this is something that requires a default style for links and a class or data attribute that must be applied to alternative links.
The type of auto-smart styling is possible with javascript though if that's an acceptable alternative. I made a quick jQuery Fiddle that would work by checking all links for the text-decoration style. This has performance drawbacks due to scanning the DOM for all links every page load. It also breaks the law of keeping styling with the CSS realm so it's up to you if it's worth it.
var links = $('a');
links.each(function (i) {
var $this = $(this);
// if this has underline
if ($this.css('text-decoration') == 'underline') {
$this.hover(
function() {
$this.css('text-decoration', 'none');
}, function() {
$this.css('text-decoration', 'underline');
});
} else {
$this.hover(
function() {
$this.css('text-decoration', 'underline');
}, function() {
$this.css('text-decoration', 'none');
});
};
});

My website - www.forex-central.net - has the Google Translate drop-down widget on the top right of every page.
Only problem is it's a bit too wide for my website (5 cm), I would need a 4 cm version (which I've seen on other sites so I know this is possible)...but I have no idea how to tweak the code.
The code Google supplies for the widget I use is:
<script type="text/javascript">function googleTranslateElementInit() { new google.translate.TranslateElement({ pageLanguage: 'en', gaTrack: true, layout: google.translate.TranslateElement.InlineLayout.SIMPLE }, 'google_translate_element');}</script><script type="text/javascript" src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>
Any help would be greatly appreciated! I'm a bit of a novice and have searched for hours on this, not getting anywhere :-/
Something like this will get you started:
.goog-te-menu-frame {
max-width:100% !important; //or whatever width you want
}
However, you would also need to do something like:
.goog-te-menu2 { //the element that contains the table of options
max-width: 100% !important;
overflow: scroll !important;
box-sizing:border-box !important; //fixes a padding issue
height:auto !important; //gets rid of vertical scroll caused by box-sizing
}
But that second part can't actually be done because the translate interface is included in your page as an iframe. Fortunately, it doesn't have its own domain, so we can access it via Javascript like this:
$('.goog-te-menu-frame').contents().find('.goog-te-menu2').css(
{
'max-width':'100%',
'overflow':'scroll',
'box-sizing':'border-box',
'height':'auto'
}
)
But that won't work until the element actually exists (it's being loaded asynchronously) so we have to wrap that in something that I got here. Put it all together, you get this:
function changeGoogleStyles() {
if($('.goog-te-menu-frame').contents().find('.goog-te-menu2').length) {
$('.goog-te-menu-frame').contents().find('.goog-te-menu2').css(
{
'max-width':'100%',
'overflow':'scroll',
'box-sizing':'border-box',
'height':'auto'
}
)
} else {
setTimeout(changeGoogleStyles, 50);
}
}
changeGoogleStyles();
Whew.
You can use that same strategy to apply other styles to the translate box or perhaps alter the table styles to have it flow vertically instead of scroll horizontally offscreen, whatever. See this answer.
EDIT:
Even this doesn't work, because Google re-applies the styles every time you click the dropdown. In this case, we try and change height and box-sizing, but Google reapplies over those, while overflow and max-width stick. What we need is to put our styles somewhere they won't get overriden and add !importants [cringes]. Inline styles will do the trick (I also replaced our selector with a variable for succinctness and what is likely a negligible performance boost):
function changeGoogleStyles() {
if(($goog = $('.goog-te-menu-frame').contents().find('body')).length) {
var stylesHtml = '<style>'+
'.goog-te-menu2 {'+
'max-width:100% !important;'+
'overflow:scroll !important;'+
'box-sizing:border-box !important;'+
'height:auto !important;'+
'}'+
'</style>';
$goog.prepend(stylesHtml);
} else {
setTimeout(changeGoogleStyles, 50);
}
}
changeGoogleStyles();
The Google Translate widget creates an iframe with content from another domain (several files from Google servers). We would have to manipulate the content inside the iframe, but this so-called cross-site scripting did not work for me. I found another solution. I downloaded two of the many files which the widget uses, so I could edit them.
Bear in mind that Google can change its API anytime. The hack will have to be adapted then.
Prerequisite:
I assume that the widget is working on your website. You just want to fit it on smaller screens. My initial code looks like:
<div id="google_translate_element"></div>
<script type="text/javascript">
function googleTranslateElementInit()
{
new google.translate.TranslateElement({pageLanguage:'de', layout: google.translate.TranslateElement.InlineLayout.SIMPLE}, 'google_translate_element');
}
</script>
<script type="text/javascript" src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>
If your initial code looks different, you might have to adapt your solution accordingly.
Special tools used:
Chrome DevTools (adapt for other browsers)
Procedure:
In Google Chrome, right-click on your page containing the Google Translate widget.
Click Inspect. A window or side pane will apper with lots of HTML info.
In the top line, select the Sources tab.
Browse the sources tree to
/top/translate.google.com/translate_a/element.js?cb=googleTranslateElementInit
Click the file in the tree. The file content will be shown.
Under the code window of element.js, there is a little button with two curly brackets { }. Click this. It will sort the code for better readability. We will need this readability in the next steps.
Right-click inside the element.js code > Save as…. Save the file inside the files hierarchy of your website, in my case:
/framework/google-translate-widget/element.js
Point your <script> tag to the local element.js.
<!--<script type="text/javascript" src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>-->
<script type="text/javascript" src="../framework/google-translate-widget/element.js?cb=googleTranslateElementInit"></script>
From now on, your website should load element.js from its local directory. Now is a good moment to check if your Google Translate widget still works. Also check in Chrome DevTools where the browser has taken the file from (Google server or local directory). It should sit in the sources tree under
/top/[your domain or IP]/framework/google-translate-widget/element.js?cb=googleTranslateElementInit
We need another file from Google servers. Browse the sources tree to
/top/translate.googleapis.com/translate_static/css/translateelement.css
Download this file after clicking the curly brackets { }. I saved it in my website files directory as
/framework/google-translate-widget/translateelement.css
In your website files directory, open element.js and change line 66:
//c._ps = b + '/translate_static/css/translateelement.css';
c._ps = '/framework/google-translate-widget/translateelement.css';
From now on, your website will also load translateelement.css from its local directory. Check this now.
Open your local translateeleent.css and append the following styles at the end:
/* Make all languages visible on small screens. */
.goog-te-menu2 {
width: 300px!important;
height: 300px!important;
overflow: auto!important;
}
.goog-te-menu2 table,
.goog-te-menu2 table tbody,
.goog-te-menu2 table tbody tr {
width: 100%!important;
height: 100%!important;
}
.goog-te-menu2 table tbody tr td {
width: 100%!important;
display: block!important;
}
.goog-te-menu2 table tbody tr td .goog-te-menu2-colpad {
visibility: none!important;
}
I borrowed the code from another answer: Google translate widget mobile overflow
The geometry might work now, but we broke another thing. The widget text showing “Select Language”, “Sélectionner une langue”, or whatever it says in you language, is locked to that language now. Since you want your other-language readers to understand the offer, the widget should adapt to their language as it used to work before our hack. Also, the listed languages’ names are affected. The reason for this bug can be found in the file element.js, which was silently tailored to our browser’s language setting. Look in element.js on lines 51 and 69
c._cl = 'fr';
_loadJs(b + '/translate_static/js/element/main_fr.js');
In my case, it was set to French (fr).
Correcting line 51 is as simple as
c._cl = 'auto'; //'fr';
Line 61 is trickier, because there is no 'auto' value available. There is a file main.js (without the _fr ending) available on Google servers, which provides English as a fallback, but we prefer the user’s language. Have a look in the file
/top/translate.googleapis.com/translate_a/l?client=…
It contains two objects. sl and tl meaning the source languages and target languages supported for translation. We have to check if the user’s browser is set to one of the target languages. There is a JavaScript constant navigator.language for this.
Edit element.js at line 69:
// determine browser language to display Google Translate widget in that language
var nl = navigator.language;
var tl = ["af","sq","am","ar","hy","az","eu","bn","my","bs","bg","ceb","ny",
"zh-TW","zh-CN","da","de","en","eo","et","tl","fi","fr","fy","gl",
"ka","el","gu","ht","ha","haw","iw","hi","hmn","ig","id","ga","is",
"it","ja","jw","yi","kn","kk","ca","km","rw","ky","ko","co","hr",
"ku","lo","la","lv","lt","lb","mg","ml","ms","mt","mi","mr","mk",
"mn","ne","nl","no","or","ps","fa","pl","pt","pa","ro","ru","sm",
"gd","sv","sr","st","sn","sd","si","sk","sl","so","es","sw","su",
"tg","ta","tt","te","th","cs","tr","tk","ug","uk","hu","ur","uz",
"vi","cy","be","xh","yo","zu"];
var gl = "";
if( tl.includes( nl )) gl = '_'+nl;
else
{
nl = nl.substring(0, 3);
if( tl.includes( nl)) gl = '_'+nl;
else
{
nl = nl.substring(0, 2);
if( tl.includes( nl)) gl = '_'+nl;
else gl = '';
}
}
_loadJs(b + '/translate_static/js/element/main'+gl+'.js');
//_loadJs(b + '/translate_static/js/element/main_fr.js');
… should do the trick.
Try using this in your CSS
.pac-container, .pac-item { width: 100px !important;}
where you can alter the with of the dropdown by altering 'the 100px' value.
This should work. Let me know if it doesn't and I'll have another look.
I would like to determine if particular elements on a page are visible when printed as controlled by CSS #media rules.
Is there a way to do this with Selenium?
I know there is the isDisplayed method, which takes the CSS into account, but there is nothing I can find to tell Selenium which media type to apply.
Is there a way to do this?
Or is there another way to test web pages to make sure the elements you want are printed (and those you don't aren't)?
Update:
For clarity, there are no plans to have a javascript print button. The users will print using the normal print functionality of the browser (Chrome, FF and IE). #media css rules will be used to control what is shown and hidden. I would like Selenium to pretend it is a printer instead of a screen, so I can test if certain elements will be visible in what would be the printed version of the page.
I've managed to write a script that does just what you want: it hides screen-only styles and sets print-only styles to be screen-only.
You need to inject the following JavaScript with Selenium:
(function pretendToBeAPrinter() {
//For looking up if something is in the media list
function hasMedia(list, media) {
if (!list) return false;
var i = list.length;
while (i--) {
if (list[i] === media) {
return true;
}
}
return false;
}
//Loop though all stylesheets
for (var styleSheetNo = 0; styleSheetNo < document.styleSheets.length; styleSheetNo++) {
//Current stylesheet
var styleSheet = document.styleSheets[styleSheetNo];
//Output debug information
console.info("Stylesheet #" + styleSheetNo + ":");
console.log(styleSheet);
//First, check if any media queries have been defined on the <style> / <link> tag
//Disable screen-only sheets
if (hasMedia(styleSheet.media, "screen") && !hasMedia(styleSheet.media, "print")) {
styleSheet.disabled = true;
}
//Display "print" stylesheets
if (!hasMedia(styleSheet.media, "screen") && hasMedia(styleSheet.media, "print")) {
//Add "screen" media to show on screen
styleSheet.media.appendMedium("screen");
}
// Get the CSS rules in a cross-browser compatible way
var rules;
try {
rules = styleSheet.cssRules;
} catch (error) {
console.log(error);
}
try {
rules = styleSheet.rules;
} catch (error) {
console.log(error);
}
// Handle cases where styleSheet.rules is null
if (!rules) {
continue;
}
//Second, loop through all the rules in a stylesheet
for (var ruleNo = 0; ruleNo < rules.length; ruleNo++) {
//Current rule
var rule = rules[ruleNo];
//Hide screen-only rules
if (hasMedia(rule.media, "screen") && !hasMedia(rule.media, "print")) {
//Rule.disabled doesn't work here, so we remove the "screen" rule and add the "print" rule so it isn't shown
console.info('Rule.media:');
console.log(rule.media)
rule.media.appendMedium(':not(screen)');
rule.media.deleteMedium('screen');
console.info('Rule.media after tampering:');
console.log(rule.media)
}
//Display "print" rules
if (!hasMedia(rule.media, "screen") && hasMedia(rule.media, "print")) {
//Add "screen" media to show on screen
rule.media.appendMedium("screen");
}
}
}
})()

There is some cases that it can be useful to use visual automation tools such as applitools.
We implements it in some of our tests, and it's great so far.

I think I have a little clever way to accomplish this:
Can I assume that the PRINT button is going to be on the html page as is the case in the jsfiddle.net link above?
Basically, can I EXCLUDE the FILE->PRINT or RIGHT CLICK->PRINT options and only assume that the only way someone can print your page is by clicking on a print button embedded in your html page as shown in the jsfiddle link above if not what are other test cases?
Finally, can I assume that your selenium tests will ONLY run in the Chrome browser and not firefox? This is important because the PRINT command behaves different in Chrome as it does in Firefox. My fix will only work w/ Chrome.
