I'am trying to migrate a plugin from v3 to v4 of TinyMCE.
In v3 you could call ed.onKeyUp.addToTop(function(){}).
The equivalent in v4 ised.on('keyup', function() {}).
Now the problem is that my keyup event gets called as last. (There are allready other keyup events registered by other plugin modules.) Is there a way to get my 'keyup' event first in the call hierarchy?
There might be some hackish way to enable you to do that, but I'll have to instinctively say that you are doing it wrong if you need it. Nevertheless you could unbind the other events, and rebind them again as a possible solution.

I am trying to write a tool that open's a website and interacts with and triggers the drag/drop behavior. I am seeing Input.dragIntercepted, Input.dispatchDragEvent functions in the documentation. But when I use these functions, I am getting a ... is not a function error. Probably, I am not using them in a proper way.
How can I use these functions to trigger drag and drop behavior of the web application? I did not find any example that shows usage of these functions.
First of all, Input.dragIntercepted really isn't a function. It's an event that will be fired, but only if you enable it, using Input.setInterceptDrags with enable set as true.
This is documented both here and here.
The azure-devops-extension-sdk has events that can be listened to for work items like onLoaded, onRefreshed, onUnloaded etc. But there's no event to listen to while the web page itself is being refreshed(navigating away). I need to stop the navigation action in case there are unsaved changes in my custom UI element. Azure DevOps does this inherently only in those cases where a standard backend field is used. My custom UI element (installed using an extension I developed) doesn't use any backend fields.
window.addEventListener function doesn't seem to work and neither did the window.beforeunload function.
Seems you are using a hub extension. We could not use the window.beforeunload event of the browser which is not working in the case of an extension because it is running in an iframe.
After go through azure-devops-extension-api, didn't find any related interface. Afraid this is not available for a customized extension right now.
I almost feel bad asking this stupid question, just upgraded to VS2012 from VS2008 and I started out by create a new Web Forms Application, and bang there you go a bunch of files and folders created. When I view the Register.aspx page, there's this line:
<asp:Button runat="server" CommandName="MoveNext" Text="Register" />
and when I run this application, it actually works, it creates a local DB and the user are inserted into that DB.
But HOW? I see no click events, I see no function in the code behind handling the MoveNext command, is this some kinda of new way of handling events? Where does the magic happen? Thank you guys
It seems like a bit of magic but it is part of the ASP.NET 4.5 Framework. It is the CreateUserWizard control on Register.aspx, there is an attribue called OnCreatedUser that wires up the code behind "click" event you are looking for. Should be called RegisterUser_CreatedUser.
http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.createuserwizard.oncreateduser.aspx
It's all part of the CreateUserWizard control. If you disassemble that class, you'll find a bunch of code that knows how to hook up to your markup. My guess is somewhere in there is something that attaches the MoveNext command to an event handler inside that user control.
When your button does a postback on the page, the lifecycle for the control is executed, so somewhere in that lifecycle is all the work.
Beginner / Intermediate developer here and trying to get a grasp on tracking down event listeners, but finding myself confused and frustrated because it always point to the library that handles the event, not the user's script. Example from the Event Listeners accordion on a select element that has the "keyup" event bound:
keyup
div.select
handler: function (e){return typeof b===i||e&&b.event.triggered===e.typet:b.event.dispatch.apply(f.elem,arguments)}
isAttribute: false
lineNumber: 3
listenerBody: "function (e){return typeof b===i||e&&b.event.triggered===e.type?t:b.event.dispatch.apply(f.elem,arguments)}"
node: div.select
sourceName: "https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"
type: "keyup"
useCapture: false
Obviously they are using jQuery, and they're doing a damn good job of it by using jQuery's $.extend method, but I still don't understand why the events accordion (in dev tools) would point to the library rather than the customized script?
Is there something really basic I missed in class? What methods are there for tracking these types of things down aside from CTRL+F in the Resources tab, which, btw did not yield any search results for "select" in the file that ACTUALLY extends/adds this listener - very odd is it not?
Update: So I feel pretty dumb about this, but the answer was right in front of my eyes - or so I think. At the top of their custom script they begin with,
define(["jquery"], function($) {
Could this be the beginning of the answer? Really what I'd like to understand is why the event would still trace back to the library when the event listener is bound within the above code,
$el.textHolder.click(function(e){
... do stuff ...
}
As far as I understand, this is because when jQuery binds an event, it doesn't bind it directly to your code, but instead to jQuery code that then dispatches the event to your code.
The Chrome devtools don't know (at this point, it seems to be in development) how jQuery binds the event, so only shows the first handler (jQuery).
The define call is part of the CommonJS Modules Standard I believe. See also RequireJS
I read from the threedubmedia site "The previous version of this plugin allowed this method to be overloaded with arguments to additionally bind handlers for "dragstart" and "dragend" in a single call, but this is no longer supported." but since I haven't actually read every line of the code I was wondering if this has already been accounted for?
Yes I upgraded to v2.2 (Updated: 2012-05-21) and it works fine for me.
I actually had an issue with 'dragend' event getting missed sometimes with v2.0.
I was doing some operations at the end of 'dragend' event (like when user stops resizing column width), but sometimes the operation won't trigger because this event was missed. Actually one had to resize rather quickly and release mouse soon to get the problem in v2.0.
After upgrading to v2.2 those issues are gone.
