  • Using KnockoutJS 2.2.0 & jQuery 1.8.2 remove all bindings from all children of #someDiv

    - by Nukeface
    I'm wanting to delete All bindings (ko.cleanNode) from all child elements of a certain div. Must be a noobie question but I can't figure out how to use jQuery to loop through all childre, grand-children, great-grand-children, etc. whilst having KnockoutJS remove the bindings of all the DOM elements. I do NOT want to remove the elements from the DOM. This is a single page application, therefore the elements are pre-loaded as embedded resources and don't get resend to a client if they were to visit the page again. If a client revisits that part of the application I'll have a function rebind the necessary elements, which currently works fine. Current setup: <html> <head> //loading all resources </head> <body> //load first element using some obscure setup <div id="firsPage" data-role="page"> <div data-role="header">@Global.header</div> <div data-role="fieldcontain"> <label for="firstInput" /> <input id="firstInput some other stuff /> </div> <div data-role="datebox <!-- some settings --> > //creates table using jQuery mobile (lots of (great-)(grand-)children) </div> <div data-role="fieldcontain"> <div id="secondInput"> <div class="checklist"> <ul> <li /> <li /> </ul> </div> </div> </div> </div> //Here the whole thing starts again <div id="secondPage" data-role="page"> <!-- repeat above innerHTML in your mind ;) --> </div> //And here again! and again... </body> The problem I'm having is that bindings of the children don't seem to get "cleaned up" when i use ko.cleanNode($('#firstPage')[0]); Or when I get the Element into a variable and then format it to ko.cleanNode($element). Is there a way to do this? Been staring at it for a good few hours now, so probably overlooking a way too obvious way of doing it... Thanks!

  • Is there a way to remove Alt-character shortcuts from controls at runtime?

    - by Dan Neely
    I have a dialog with a number of Alt-Letter shortcuts on labels for textboxes/etc. This dialog can present data in either an editable or a read-only mode. I've received a request to hide the underlines for the shortcuts if the dialog is in read only mode. Other than editing the label text at runtime (ugh) is there any way to remove them? If you don't know what I'm referring to by alt-Letter shortcuts see this question.

  • How do I remove database name from SQL Server generated script?

    - by bucha
    Anytime I use 'script table as' - 'Insert To' (or other command), the script generated automatically places the database name in the script. Such as: INSERT INTO [DatabaseName].[dbo].[tblToBeInserted] ... While not a huge problem to just delete it, it has slipped by a few times and the script breaks if run on a different server with a different database name but has the same schema. (Such as running on [DatabaseName.Test]) Is there an option I can change, or can I modify the output in any way to remove this?

    - by user80003
    Hello everyone. How can I remove the . and .. from a path in Delphi (not using .NET). I need a function, so I can pass it something like 'c:\program files..\program files...', and I want the function to return to me 'c:\'. Can Delphi do that on its own? Or do I need to do it myself?

  • How to get javascript object references or reference count?

    - by Tauren
    How to get reference count for an object Is it possible to determine if a javascript object has multiple references to it? Or if it has references besides the one I'm accessing it with? Or even just to get the reference count itself? Can I find this information from javascript itself, or will I need to keep track of my own reference counters. Obviously, there must be at least one reference to it for my code access the object. But what I want to know is if there are any other references to it, or if my code is the only place it is accessed. I'd like to be able to delete the object if nothing else is referencing it. If you know the answer, there is no need to read the rest of this question. Below is just an example to make things more clear. Use Case In my application, I have a Repository object instance called contacts that contains an array of ALL my contacts. There are also multiple Collection object instances, such as friends collection and a coworkers collection. Each collection contains an array with a different set of items from the contacts Repository. Sample Code To make this concept more concrete, consider the code below. Each instance of the Repository object contains a list of all items of a particular type. You might have a repository of Contacts and a separate repository of Events. To keep it simple, you can just get, add, and remove items, and add many via the constructor. var Repository = function(items) { this.items = items || []; } Repository.prototype.get = function(id) { for (var i=0,len=this.items.length; i<len; i++) { if (items[i].id === id) { return this.items[i]; } } } Repository.prototype.add = function(item) { if (toString.call(item) === "[object Array]") { this.items.concat(item); } else { this.items.push(item); } } Repository.prototype.remove = function(id) { for (var i=0,len=this.items.length; i<len; i++) { if (items[i].id === id) { this.removeIndex(i); } } } Repository.prototype.removeIndex = function(index) { if (items[index]) { if (/* items[i] has more than 1 reference to it */) { // Only remove item from repository if nothing else references it this.items.splice(index,1); return; } } } Note the line in remove with the comment. I only want to remove the item from my master repository of objects if no other objects have a reference to the item. Here's Collection: var Collection = function(repo,items) { this.repo = repo; this.items = items || []; } Collection.prototype.remove = function(id) { for (var i=0,len=this.items.length; i<len; i++) { if (items[i].id === id) { // Remove object from this collection this.items.splice(i,1); // Tell repo to remove it (only if no other references to it) repo.removeIndxe(i); return; } } } And then this code uses Repository and Collection: var contactRepo = new Repository([ {id: 1, name: "Joe"}, {id: 2, name: "Jane"}, {id: 3, name: "Tom"}, {id: 4, name: "Jack"}, {id: 5, name: "Sue"} ]); var friends = new Collection( contactRepo, [ contactRepo.get(2), contactRepo.get(4) ] ); var coworkers = new Collection( contactRepo, [ contactRepo.get(1), contactRepo.get(2), contactRepo.get(5) ] ); contactRepo.items; // contains item ids 1, 2, 3, 4, 5 friends.items; // contains item ids 2, 4 coworkers.items; // contains item ids 1, 2, 5 coworkers.remove(2); contactRepo.items; // contains item ids 1, 2, 3, 4, 5 friends.items; // contains item ids 2, 4 coworkers.items; // contains item ids 1, 5 friends.remove(4); contactRepo.items; // contains item ids 1, 2, 3, 5 friends.items; // contains item ids 2 coworkers.items; // contains item ids 1, 5 Notice how coworkers.remove(2) didn't remove id 2 from contactRepo? This is because it was still referenced from friends.items. However, friends.remove(4) causes id 4 to be removed from contactRepo, because no other collection is referring to it. Summary The above is what I want to do. I'm sure there are ways I can do this by keeping track of my own reference counters and such. But if there is a way to do it using javascript's built-in reference management, I'd like to hear about how to use it.
