I'm coding a basic video marquee and one of the key requirements is that the videos need to be able to advance while keeping the player in full screen.
Using Video.js (4.1.0) I have been able to get everything work correctly except that I cannot get the captions to change when switching to another video.
Either inserting a "track" tag when the player HTML is first created or adding a track to the 'options' object when the player is initialized are the only ways I can get the player to display the "CC" button and show captions. However, I cannot re-initialize the player while in full screen so changing the track that way will not work.
I have tried addTextTrack and addTextTracks and both show that the tracks have been added - using something like console.log(videoObject.textTracks()) - but the player never shows them or the "CC" button.
Here is my code, any help is greatly appreciated:
;(function(window,undefined) {

{"volume":"70","title":"TEST 1","url":"test1.mp4","type":"mp4"},

The current VideoJS implementation (4.4.2) loads every kind of text tracks (subtitles, captions, chapters) on initialization time of the player itself, so it grabs correctly only those, which are defined between the <video> tags.
EDIT: I meant it does load them when calling addTextTrack, but the player UI will never update after initialization time, and will always show the initialization time text tracks.
One possible workaround is if you destroy the complete videojs player and re-create it on video source change after you have refreshed the content between the <video> tags. So this way you don't update the source via the videojs player, but via dynamically adding the required DOM elements and initializing a new player on them. Probably this solution will cause some UI flashes, and is quite non-optimal for the problem. Here is a link about destroying the videojs player
Second option is to add the dynamic text track handling to the existing code, which is not as hard as it sounds if one knows where to look (I did it for only chapters, but could be similar for other text tracks as well). The code below works with the latest official build 4.4.2. Note that I'm using jQuery for removing the text track elements, so if anyone applies these changes as is, jQuery needs to be loaded before videojs.
Edit the video.dev.js file as follows:
1: Add a clearTextTracks function to the Player
vjs.Player.prototype.clearTextTracks = function() {
var tracks = this.textTracks_ = this.textTracks_ || [];
for (var i = 0; i != tracks.length; ++i)
$(tracks[i].el()).remove();
tracks.splice(0, tracks.length);
this.trigger("textTracksChanged");
};
2: Add the new 'textTracksChanged' event trigger to the end of the existing addTextTrack method
vjs.Player.prototype.addTextTrack = function(kind, label, language, options) {
...
this.trigger("textTracksChanged");
}
3: Handle the new event in the TextTrackButton constructor function
vjs.TextTrackButton = vjs.MenuButton.extend({
/** #constructor */
init: function(player, options) {
vjs.MenuButton.call(this, player, options);
if (this.items.length <= 1) {
this.hide();
}
player.on('textTracksChanged', vjs.bind(this, this.refresh));
}
});
4: Implement the refresh method on the TextTrackButton
// removes and recreates the texttrack menu
vjs.TextTrackButton.prototype.refresh = function () {
this.removeChild(this.menu);
this.menu = this.createMenu();
this.addChild(this.menu);
if (this.items && this.items.length <= this.kind_ == "chapters" ? 0 : 1) {
this.hide();
} else
this.show();
};
Sorry, but for now I cannot link to a real working example, I hope the snippets above will be enough as a starting point to anyone intrested in this.
You can use this code when you update the source to a new video. Just call the clearTextTracks method, and add the new text tracks with the addTextTrack method, and the menus now should update themselves.
Doing the exact same thing (or rather NOT doing the exact same thing)... really need to figure out how to dynamically change / add a caption track.
This works to get it playing via the underlying HTML5, but it does not show the videojs CC button:
document.getElementById("HtmlFiveMediaPlayer_html5_api").innerHTML = '<track label="English Captions" srclang="en" kind="captions" src="http://localhost/media/captiontest/demo_Brian/demo_h264_1.vtt" type="text/vtt" default />';

Hi i am trying to add two new fields to the Barcode mobile view. I went through the default js code of odoo, but didn't find a way to add my custome fields to it.
Here is the default code
stock_barcode/static/src/js/client_action/lines_widget.js
init: function (parent, page, pageIndex, nbPages) {
this._super.apply(this, arguments);
this.page = page; #don't know where this argument page coming from in argument list.
this.pageIndex = pageIndex;
this.nbPages = nbPages;
this.mode = parent.mode;
this.groups = parent.groups;
this.model = parent.actionParams.model;
this.show_entire_packs = parent.show_entire_packs;
this.displayControlButtons = this.nbPages > 0 && parent._isControlButtonsEnabled();
this.displayOptionalButtons = parent._isOptionalButtonsEnabled();
this.isPickingRelated = parent._isPickingRelated();
this.isImmediatePicking = parent.isImmediatePicking ? true : false;
this.sourceLocations = parent.sourceLocations;
this.destinationLocations = parent.destinationLocations;
// detect if touchscreen (more complicated than one would expect due to browser differences...)
this.istouchSupported = 'ontouchend' in document ||
'ontouchstart' in document ||
'ontouchstart' in window ||
navigator.maxTouchPoints > 0 ||
navigator.msMaxTouchPoints > 0;
},
In _renderLines function,
_renderLines: function () {
//Skipped some codes here
// Render and append the lines, if any.
var $body = this.$el.filter('.o_barcode_lines');
console.log('this model',this.model);
if (this.page.lines.length) {
var $lines = $(QWeb.render('stock_barcode_lines_template', {
lines: this.getProductLines(this.page.lines),
packageLines: this.getPackageLines(this.page.lines),
model: this.model,
groups: this.groups,
isPickingRelated: this.isPickingRelated,
istouchSupported: this.istouchSupported,
}));
$body.prepend($lines);
for (const line of $lines) {
if (line.dataset) {
this._updateIncrementButtons($(line));
}
}
$lines.on('click', '.o_edit', this._onClickEditLine.bind(this));
$lines.on('click', '.o_package_content', this._onClickTruckLine.bind(this));
}
In the above code, you can see this.page.lines field, i need to add my custom two more fields.
Actually it's dead-end for me.
Any solution?
I'm developing an App that gets data from ACS, the post objects.
In my app there is button and when the users click that button it get the posts data.
In every post there is also a photo_id, which allows me to get the photo url from the cloud.
But there is a problem, it has a callback function and by the time the callback occurs it is too late.
Anyway, the code below only shows the last post with a photo, the first post doesn't have a photo.
(there are only 2 post objects so far).
I believe the problem is in the callback, but I can't seem to fix it.
Hope you guys can help me out, thanks in advance!
Here is my code:
function getCarsClick() {
Cloud.Posts.query({
page: 1,
per_page: 20
}, function (e) {
if (e.success) {
var tableData = [];
for (var i = 0; i < e.posts.length; i++) {
var post = e.posts[i];
var row = Titanium.UI.createTableViewRow();
var title = Titanium.UI.createLabel({
text:post.title,
font:{fontSize:18,fontWeight:'bold'},
color:'#ef349d',
width:'auto',
textAlign:'left',
top:2,
left:40,
height:30
});
var subtitle = Titanium.UI.createLabel({
text:post.content,
font:{fontSize:12,fontWeight:'normal'},
color:'#000000',
width:'auto',
textAlign:'left',
bottom:10,
left:60,
height:32
});
row.add(title);
row.add(subtitle);
row.hasChild=true;
row.height = 80;
row.selectedBackgroundColor = '#ef349d';
Cloud.Photos.show({
photo_id: post.photo_id
}, function (e) {
if (e.success) {
var photo = e.photos[0];
var img1 = Ti.UI.createImageView({image:photo.urls.square_75,width:30,height:30,left:2, top:2});
row.add(img1);
} else {
alert('Error:\n' +
((e.error && e.message) || JSON.stringify(e)));
}
});
tableData.push(row);
}
//add table data
$.tableview1.setData(tableData);
} else {
alert('Error:\n' +
((e.error && e.message) || JSON.stringify(e)));
}
});
}
If you pass a photo into the post using the default parameter provided, the image should come back by default and not require you to make an additonal API call to get the photo.
I would also suggest if you are just starting out to use Alloy and more importantly use ListViews not TableView

You have to set the enablejsapi parameter to 1 in your iframe embed link.
By default, the parameter is set to 0 and unless you set it to 1, the callbacks won't work.

I am creating a simple app using Sencha Touch where I'm dynamically creating container with textfields, textareafields etc. when the user needs to add new container with components. The problem now is when the clear icon on the textareafield is tapped it clears the text, but I would like to know which textareafield has been cleared. Can anyone help me in this please?
This is how I created container .
var childObj2 = {};
childObj2.xtype = 'container';
var type = 'vbox';
var layout = {}
layout.type = type;
childObj1.layout = layout;
var txtarea= {};
txtarea.xtype = 'textareafield';
txtarea.id = "txt51";
txtarea.flex = 3;
txtarea.maxRows = 7;
txtarea.placeHolder = 'Type here';
txtarea.value = value['notes'];
txtarea.inputCls = 'txtareaStyle'
txtarea.clearicontap = "clearText";
How to add clearicontap listener to this?
When you you create a textfield simply add a listener to it for the clearicontap event and that callback will get executed for each of the fields.
For example:
var container = Ext.create('Ext.Container', {});
for (var i=1; i<=3; i++) {
var field = Ext.create('Ext.field.Text', {
id: 'textfieldnumber' + i,
listeners: {
clearicontap: function() {
alert("Tapped clear icon on text field number: " + i + "!");
}
}
});
container.add(field);
}
[EDIT]
I answer the question you make after your edit:
I am using the standard way of creating Sencha components through Ext.create(), and I would suggest you to switch to the same way. It is not clear by the code you posted how those Javascript objects are actually transformed into Ext components. Anyway, they are very likely components configurations, so I guess you could try:
txtarea.listeners = {
clearicontap: function() {
alert("Tapped clear icon on text field");
}
}
I am currently implementing a custom data source in a Windows8 application. However, I got some trouble with it: no data is displayed.
First, here is the code:
var dataArray = [
{ title: "Basic banana", text: "Low-fat frozen yogurt", picture: "images/60banana.png" },
// Other data taken from Windows8 ListView quick start
{ title: "Succulent strawberry", text: "Sorbet", picture: "images/60strawberry.png" }
];
var searchAdDataAdapter = WinJS.Class.define(
function () {}, // Constructor
{
itemsFromIndex: function (requestIndex, countBefore, countAfter) {
var that = this;
if (requestIndex >= that._maxCount) {
return WinJS.Promise.wrapError(new WinJS.ErrorFromName(UI.FetchError.doesNotExist));
}
var fetchSize, fetchIndex;
// See which side of the requestIndex is the overlap.
if (countBefore > countAfter) {
// Limit the overlap
countAfter = Math.min(countAfter, 10);
// Bound the request size based on the minimum and maximum sizes.
var fetchBefore = Math.max(
Math.min(countBefore, that._maxPageSize - (countAfter + 1)),
that._minPageSize - (countAfter + 1)
);
fetchSize = fetchBefore + countAfter + 1;
fetchIndex = requestIndex - fetchBefore;
} else {
countBefore = Math.min(countBefore, 10);
var fetchAfter = Math.max(Math.min(countAfter, that._maxPageSize - (countBefore + 1)), that._minPageSize - (countBefore + 1));
fetchSize = countBefore + fetchAfter + 1;
fetchIndex = requestIndex - countBefore;
}
// Create an array of IItem objects:
// results =[{ key: key1, data : { field1: value, field2: value, ... }}, { key: key2, data : {...}}, ...];
for (var i = 0, itemsLength = dataArray.length ; i < itemsLength ; i++) {
var dataItem = dataArray[i];
results.push({
key: (fetchIndex + i).toString(),
data: dataArray[i]
});
}
// Get the count.
count = dataArray.length;
return {
items: results, // The array of items.
offset: requestIndex - fetchIndex, // The index of the requested item in the items array.
totalCount: count
};
},
getCount: function () {
return dataArray.length;
}
}
);
var searchAdDataSource = WinJS.Class.derive(WinJS.UI.VirtualizedDataSource, function () {
this._baseDataSourceConstructor(new searchAdDataAdapter());
});
// Create a namespace to make the data publicly
// accessible.
var publicMembers = {
itemList: new searchAdDataSource()
};
WinJS.Namespace.define("DataExample", publicMembers);
I know the code is a little bit long, but the major part of it is taken from official Microsoft custom data source quick start.
I tried to debug it, but it seems the code contained in itemFromIndex is never used (my breakpoint is never reached).
The HTML code is:
<div id="basicListView" data-win-control="WinJS.UI.ListView"
data-win-options="{itemDataSource : DataExample.itemList.dataSource}">
</div>
I do not use any template for the moment, to simplify the code as more as I can. Data are normally displayed in text this way (but nothing appears).
Have one of this great community any idea?
Furthermore, I do not understand the countBefore and countAfter parameters, even with the documentation. Can somebody explain it to me with other words?
Thanks a lot! :)
Try modifying your HTML code to the following:
<div id="basicListView" data-win-control="WinJS.UI.ListView"
data-win-options="{itemDataSource : DataExample.itemList}">
</div>
No need to call the .datasource member, as you are talking to the datasource directly.
