Dojo lightbox problem - dojo

I made a custom basic lightbox with Dojo to be used with forms and data. Not really dealing with images or such.
The problem that I seem to be facing is this. When Dojo makes a call via AJAX to ajaxtb.php with specific code for example; ?f=login or ?f=register the page is loaded. When you I close the lightbox and try to view something different say ?f=stuff the lightbox will show what ever was before it be it ?f=login or what ever, it will show it until ?f=stuff is fully loaded.
Here is the code for the lightbox, also can some one tell me how to optimize it since its pretty redundant at the moment and very basic.
dojo.ready(function(){
#loads logout confirmation
dojo.query("#jsLogoutPromp").connect("onclick", function(){
dojo.byId("qpbox-title-text").innerHTML = "Logout Confirmation";
dojo.query("#qpbox-content").style("display", "block");
dojo.query("#qpbox-overlay").style("display", "block");
dojo.xhrGet({
url: "ajaxtb.php?f=logout",
load: function(newContent) {
dojo.byId("utm").innerHTML = newContent;
},
// The error handler
error: function() {
// Do nothing -- keep old content there
}
});
});
#loads options to upload profile photo
dojo.query("#jsUserPhotoPromp").connect("onclick", function(){
dojo.byId("qpbox-title-text").innerHTML = "Upload Photo";
dojo.query("#qpbox-content").style("display", "block");
dojo.query("#qpbox-overlay").style("display", "block");
dojo.xhrGet({
url: "ajaxtb.php?f=display_pic",
load: function(newContent) {
dojo.byId("utm").innerHTML = newContent;
},
// The error handler
error: function() {
// Do nothing -- keep old content there
}
});
});
#closes everything when clicked well technically hides everything
dojo.query("#qpbox-close").connect("onclick", function(){
dojo.query("#qpbox-content").style("display", "none");
dojo.query("#qpbox-overlay").style("display", "none");
});
#shows up for logout only, same as above code, but does not work since the original id is included in ajax.php?f=logout
dojo.query("#qpbox-stay").connect("onclick", function(){
dojo.query("#qpbox-content").style("display", "none");
dojo.query("#qpbox-overlay").style("display", "none");
});
});
The functions responsible for closing everything is qpbox-close and qpbox-stay. Technically both only hide the lightbox not close. The other problem is with qpbox-stay. qpbox-stay id is located in ajax.php?f=logout and when clicked it does not close the lightbox so not sure whats the problem with it.
here is the code for ajax.php
if($_GET['f'] == 'logout') {
echo '
<p>Are you sure you want to exit right now?</p>
<br>
<button type="submit">Logout</button> No, I wana Stay
';
}
Thanks

You can use dojo.empty(dojo.byId('utm')) before showing the lightbox to delete all the contents.
Also, you can refactor your code quite a bit. Both click handlers do basically the same thing. So why not refactor them in a function?
dojo.ready(function() {
function showLightBox(title, url) {
var utm = dojo.byId('utm');
dojo.empty(utm);
dojo.byId("qpbox-title-text").innerHTML = title;
dojo.style(dojo.byId("qpbox-content"), "display", "block");
dojo.style(dojo.byId("qpbox-overlay"), "display", "block");
dojo.xhrGet({
url: url,
load: function(newContent) {
utm.innerHTML = newContent;
},
// The error handler
error: function() {
// Do nothing -- keep old content there
}
});
}
function hideLightBox() {
dojo.style(dojo.byId("qpbox-content"), "display", "none");
dojo.style(dojo.byId("qpbox-overlay"), "display", "none");
}
dojo.connect(dojo.byId('jsLogoutPromp'), 'onclick', function() {
showLightBox("Logout Confirmation", "ajaxtb.php?f=logout");
});
// ...
dojo.connect(dojo.byId('qpbox-close'), 'onclick', hideLightBox);
});
You can try and connect to #qpbox-stay after you've loaded the content, or if using Dojo 1.6, you can use NodeList.delegate like:
dojo.require('dojox.NodeList.delegate');
dojo.query('#utm').delegate('#qpbox-stay', 'onclick', hideLightBox);
That will connect to #utm which is already loaded, but work for #qpbox-stay only. It works with event bubbling, similar to jquery.live(). See http://davidwalsh.name/delegate-event

disable scrolling when trigger owl carousel on mobile device

I noticed when using Owl Carousel 2, while slide the item in mobile viewing, the browser also can be move up and down. Try to disabling the scroll function when trigger the Owl Carousel 2 prev and next function in mobile but it still doesn't work.
$('.owl-carousel').owlCarousel({
loop:true,
margin:5,
nav:true,
items:2,
});
// $('.owl-carousel').bind("mousewheel", function() {return false;});
$('.owl-carousel').bind('touchmove', function(e){e.stopPropagation(); alert('allow scroll');});
Appreciated the answer from expert out here.
Thank you.
I made this work with the help of OwlCarousel2 events.
There are 2 events we can use together for this purpose:
drag.owl.carousel fires when user start to drag
dragged.owl.carousel fires when dragging finished
And this make it work like how we want it:
var owl = $('.owl-carousel');
owl.owlCarousel({
// your options
});
owl.on('drag.owl.carousel', function(event) {
$('body').css('overflow', 'hidden');
});
owl.on('dragged.owl.carousel', function(event) {
$('body').css('overflow', 'auto');
});
So; it use css overflow to disable scrolling when dragging started and enables it back when it finished.
This works on iOS & VueJS.
var owl = $('.owl-carousel');
owl.owlCarousel({
// your options
})
// disable scroll
owl.on('drag.owl.carousel', function(event) {
document.ontouchmove = function (e) {
e.preventDefault()
}
})
// enable scroll
owl.on('dragged.owl.carousel', function(event) {
document.ontouchmove = function (e) {
return true
}
})
look for the below piece of code in custom.js file of your project
Owl.Defaults = {
items: 3,
loop: false,
center: false,
rewind: false,
mouseDrag: true,
touchDrag: true,}
change the things to below:-
touchDrag:false,
and owl-carousel will simply stop scrolling horizontally both on mobile and desktop drag!
For owlcarousel2, you can use mouseDrag option.
$('.owl-carousel').owlCarousel({
mouseDrag:false
});
Reference https://owlcarousel2.github.io/OwlCarousel2/docs/api-options.html
in owl.js
mouseDrag: false,
touchDrag: false,
pullDrag: false,
freeDrag: false,

Disable the escape key in dojo

I have a requirement to disable the escape key when the dialog is open.currently when i click the escape button the dialog closes and the transaction is submitting.I tried the following code snippet but its not working chrome.
dojo.connect(dialog, "onKeyPress", function(e){
var key = e.keyCode || e.charCode;
var k = dojo.keys;
if (key == k.ESCAPE) {
event.preventDefault();
d.stopEvent(event);
}
});
Could you please help on this..i have searched a lot and havent found a suitable solution for my problem.
Thanks inadvance..
Dojo uses the _onKey event for accessibility. You can override it by using:
dialog._onKey = function() { }
I wrote an example JSFiddle, hitting the Escape key should not work anymore.
In the event you want to override the escape key in all dialogs (rather than a particular instance), you can use dojo/aspect:
require(['dojo/aspect', 'dijit/Dialog'], function (Aspect, Dialog) {
Aspect.around(Dialog.prototype, '_onKey', function (original) {
return function () { }; // no-op
});
});
You can create an extension for the Dialog widget like this in a new file:
define(["dojo/_base/declare", "dijit/Dialog"],
function(declare, Dialog){
return declare(Dialog, {
//Prevents the 'ESC' Button of Closing the dialog
_onKey: function() { }
});
});
save the file into dojo Directory (say: dojo/my/my_dialog.js),
and instead of calling: 'dijit/Dialog', just call: 'my/my_dialog'.
this will save you the hard work of editing each Dialog call,
And the same thing to the "dojox/widget/DialogSimple" Widget.

WinJS Listview shows undefined when navigating quickly

I have a WinJS application with listviews in which if quickly navigate between pages before the listview is fully loaded, the next page shows the listview with all elements in it bound as "undefined".
So say I have a hub page with a "to do" that is filtered to only show 6 items, and there is a header that navigates to the full "to do" page, when the hub page is displayed but before it is fully loaded I click on the header link to the "to do" page, the app then goes to the "to do" page, but the items show up with all the properties in the tile as "undefined".
I am using IndexedDB as my data store.
My home page code looks like this:
WinJS.UI.Pages.define("/pages/home/home.html", {
ready: function (element, options) {
WinJS.Utilities.query("a").listen("click", function (e) {
e.preventDefault();
WinJS.Navigation.navigate(e.currentTarget.href);
}, false);
viewModel = new HomeViewModel(element);
viewModel.load(); //loads from indexed db
},
//etc...
To Do Page:
WinJS.UI.Pages.define("/pages/ToDo/ToDo.html", {
ready: function (element, options) {
viewModel = new ToDoViewModel(element);
viewModel.load();
},
etc//
I know there isn't much to go off, but any ideas would be appreciated.
Also tips on how to debug something like this would be great.
Update
I narrowed it down to this one line from the Hub Page:
myLib.GetData(todaysDate, function (result) {
that.trendsModel.today = result;
WinJS.Binding.processAll(that.el.querySelector("#dataPanel"), that.trendsModel); //<--Right Here
});
If I remove that, then when I load the second page the data doesn't show as undefined. What is interesting is the data initially shows correctly on the second page and then it changes to "undefined".
Solution
My fix:
myLib.GetData(todaysDate, function (result) {
var element = that.el.querySelector("#dataPanel");
that.trendsModel.today = result;
if(element) {
WinJS.Binding.processAll(element, that.trendsModel);
}
});
At the point when when the callback returns, I am already on the second page. So the selector was not found returning null. If you pass null to processAll it tries to bind the whole page which is why I was able to see the correct data for a second then it changes to undefined...Wow, what a doozy. I guess it makes sense but what a pain to find.
Hope it helps someone in the future :)
Your ToDoViewModel, and HomeViewModel need to be observable. This means they need to mix in from WinJS.Binding.mixin, and for the properties that you pull in asynchronously, they need to call this.notify("propertyName", newVal, oldVal) from the property setter.
Note that you need to have getter/setter properties. e.g.
var bindingBase = WinJS.Class.mix(function() {}, WinJS.Binding.mixin);
WinJS.Namespace.define("YourNamespace", {
ToDoViewModel: WinJS.Class.derive(bindingBase, function constructor() {
}, {
_titleStorage: "",
title: {
get: function() { return this._titleStorage; },
set: function(newValue) {
if(newValue === this._titleStorage) {
return;
}
var old = this._titleStorage;
this._titleStorage = newValue;
this.notify("title", newValue, old);
}
}
}),
});
myLib.GetData(todaysDate, function (result) {
var element = that.el.querySelector("#dataPanel");
that.trendsModel.today = result;
if(element) {
WinJS.Binding.processAll(element, that.trendsModel);
}
});
At the point when when the callback returns, I am already on the second page. So the selector was not found returning null. If you pass null to processAll it tries to bind the whole page which is why I was able to see the correct data for a second then it change to undefined...Wow, what doozy.

DOJO ContentPane.set("href", "..." ) not loading content

I have a ContentPane defined as follows:
<div id="searchResultsContentPane" data-dojo-type="dijit.layout.ContentPane" data-dojo-props='splitter:false, region:"center"'></div>
I am trying to dynamically set the href when a button in another ContentPane is pressed:
var searchResultsContentPane = dijit.byId("searchResultsContentPane");
searchResultsContentPane.set("href", "modules/content_panes/callrecords.php");
For some reason this doesn't seem to be working. The content pane flashes loading then goes back to white and FireBug doesn't give me usable info. This is all it shows:
If you cant read that it says in red:
GET http://cdr.homelinux.net:10001/Mike/modules/content_panes/callrecords.php
callrecords.php loads just fine if I set it with html as a data-dojo-props property.
Thanks
Page was refreshing. Used the following code to properly load the content pane.
function sendSearchForm() {
// format taken from http://dojotoolkit.org/reference-guide/1.7/dojo/xhrPost.html
var form = dojo.byId("search_form");
dojo.connect(form, "onsubmit", function(event) {
dojo.stopEvent(event);
var xhrArgs = {
form: dojo.byId("search_form"),
handleAs: "text",
load: function(data){
loadAdvancedSearchResultsTable();
//var searchResultsContentPane = dijit.byId("searchResultsContentPane");
//searchResultsContentPane.set("href", "modules/content_panes/test_module.html");
},
error: function(error){
// TODO Handle errors
}
}
// Call the asynchronous xhrPost
//dojo.byId("response").innerHTML = "Form being sent..."
var deferred = dojo.xhrPost(xhrArgs);
});
}
dojo.ready(sendSearchForm);

create a window chrome with an exception in back

I'd just like to create a new window from the background page and put it in back. I tried focused:false but it doesn't seem to make the trick. I tried to save the previous windowId and tabId and update it after having creating the new window but it doesn't solve the problem neither.
Do you know how we can do that?
Here is my code:
function saveTabId() {
// Get the current tab
chrome.tabs.getSelected(null,function(tab){
if (tab != 'undefined') {
if (tab.windowId != windowId) {
currentTabId = tab.id;
currentWindowId = tab.windowId;
}
chrome.windows.create({url:"http://www.google.com", width:100, height:100, top:0, left:0, focused:false}, function() {
chrome.tabs.get(currentTabId, function(tab) {
chrome.windows.update(tab.windowId, {}, function(w) {
chrome.tabs.update(tab.id, {selected:true});
});
});
});
}
});
}
I launched this code at the beginning of background.html and when I refresh the extension, the window is on top of the extensions tab.
P.S: something more strange the window is on top of the extensions tab and when I change tab in this window, the new window stays on top of the other one even if I click and type text in the other one...
I got it kind of working, but popup window is still showing up for a moment before going underneath the current window:
chrome.windows.create({url:"http://www.google.com", width:100, height:100, top:0, left:0, focused:false}, function() {
chrome.windows.update(currentWindowId, {focused:true});
});
Thanks, here is the code I'm using now. The problem in the code of the question was the focus to the other window before updating it. It is strange, when you focus on a window, it doesn't show it on top of the others.
function focusTab(tabId) {
chrome.tabs.get(tabId, function(tab) {
chrome.windows.update(tab.windowId, {}, function(w) {
chrome.tabs.update(tab.id, {selected:true});
});
});
}
