  • How do you implement file drag-and-drop upload in Google Chrome?

    - by Chris R
    I've found several tutorials online about implementing file drag/drop with Firefox 3.6 (they involve using a FileReader object to get the file binary data). However, I cannot create a FileReader object in Chrome on Windows or Mac. Does anyone know what the API is to read and manipulate data from a drag-and-dropped file in Chrome? If I can get the binary data of the file, I already have the rest of the code to perform the upload. Note: I've also tried using the getAsBinary() function call on the file object of the drag event (event.dataTransfer.file) but I believe that is a Mozilla-specific function and not implemented in Chrome. Also, I'm not interested in a solution using google gears or one that requires a user to select files from a dialog. I'm specifically trying to implement a drag-and-drop file upload.

  • How to implement "drag n drop" user interface on website?

    - by Nikkeloodeni
    Hello, I was wondering what would be the best way to implement some kind of "drag n drop" user interface? What i mean is that there would be one main page and every link click (eg. other sections like about, gallery, contact form) would open a new drag n drop element on top of that main page. Something like windows desktop where you can move your application windows around the screen. Would it be best to call different functions with AJAX when a link is clicked? Like "gallery" link would call gallery-function and retrieve dynamically generated contents of that "window" with AJAX call and then just load that stuff on some div? Or would some other type of approach suit better for this? I hope I was able to explain this clearly enough. I'm looking for a proper "design pattern" to implement this. All suggestions are wellcome! :)

  • How to create a drop down menu like the one displayed on Amazon?

    - by webdev_newbee
    I am kind of new to web development. I am trying to create a drop down menu, something I have now is like: <select> <option value="volvo">Volvo</option> <option value="saab">Saab</option> <option value="opel">Opel</option> <option value="audi">Audi</option> </select> but this is not exactly what I want. I want to create a drop down list very similar to the one on Amazon.com (the dropdown list beside "Search"), shown in following pic. so whenever user click on the button, the list will be displayed in the button as text. Please feel free to give me any ideas. Thank you,

  • HTML5 drag & drop: The dragged element content is missing in Webkit browsers.

    - by Cibernox
    I'm trying to implement something similar to a cart where you can drop items from a list. This items (<li> elements) has some elements inside (divs, span, and that stuff). The drag and drop itself works great. But the dragged element's image doesn't show its content in Webkit browsers. My list element has a border an a background color. In Firefox, the image is the whole item. In Webkit browsers, only the dragged element without content. I see the background and border, but without text inside. I tried to make a copy of the element and force it to be the image, but doesn't work. var dt = ev.originalEvent.dataTransfer; dt.setDragImage( $(ev.target).clone()[0], 0, 0); I have a simplified example that exhibit the same behavior: http://jsfiddle.net/ksnJf/1/

  • QML: Overriding a signal handler from other element

    - by user3490458
    Is it possible to override an elements action (eg onTriggered() of a Timer) from within the onClick() of a button? Something like so- Button { id: centerBtn objectName: "button" onClicked: { delaytimer.running = true; delayTimer.onTriggered {}; // override here } Timer { id: delaytimer interval: 1000 running: false repeat: false onTriggered: //something implemented here } }

  • implementing dynamic query handler on historical data

    - by user2390183
    EDIT : Refined question to focus on the core issue Context: I have historical data about property (house) sales collected from various sources in a centralized/cloud data source (assume info collection is handled by a third party) Planning to develop an application to query and retrieve data from this centralized data source Example Queries: Simple : for given XYZ post code, what is average house price for 3 bed room house? Complex: What is estimated price for an house at "DD,Some Street,XYZ Post Code" (worked out from average values of historic data filtered by various characteristics of the house: house post code, no of bed rooms, total area, and other deeper insights like house building type, year of built, features)? In addition to average price, the application should support other property info ** maximum, or minimum price..etc and trend (graph) on a selected property attribute over a period of time**. Hence, the queries should not enforce the search based on a primary key or few fixed fields In other words, queries can be What is the change in 3 Bed Room house price (irrespective of location) over last 30 days? What kind of properties we can get for X price (irrespective of location or house type) The challenge I have is identifying the domain (BI/ Data Analytical or DB Design or DB Query Interface or DW related or something else) this problem (dynamic query on historic data) belong to, so that I can do further exploration My findings so far I could be wrong on the following, so please correct me if you think so I briefly read about BI/Data Analytics - I think it is heavy weight solution for my problem and has scalability issues. DB Design - As I understand RDBMS works well if you know Data model at design time. I am expecting attributes about property or other entity (user) that am going to bring in, would evolve quickly. hence maintenance would be an issue. As I am going to have multiple users executing query at same time, performance would be a bottleneck Other options like Graph DB (http://www.tinkerpop.com/) seems to be bit complex (they are good. but using those tools meant for generic purpose, make me think like assembly programming to solve my problem ) BigData related solution are to analyse data from multiple unrelated domains So, Any suggestion on the space this problem fit in ? (Especially if you have design/implementation experience of back-end for property listing or similar portals)

  • design an extendible and pluggable business logic flow handler in php

    - by Broncha
    I am working on a project where I need to allow a pluggable way to inject business processes in the normal data flow. eg There is an ordering system. The standard flow of the application is A consumer orders an item. Pays for it and card is authorized. Admin captures the payment. Order is marked as complete and item is shipped. But this process may vary (extra steps in between) for different clients. Say a client would need to validate the location of the consumer before he is presented with a credit card form, OR his policies might require some other processes in between. I am thinking of using State Pattern for processing orders, saving the current state of the order in database, and initializing the state of order from the saved state. I would also need some mechanism, where a small plugin would be able to inject business specific states in the state machine. Am I thinking the right way? Are there already implemented patterns for this kind of situation? I am working with Codeigniter and basically this would mean for me, to redirect to proper controller according to the current state of the order. Like, if the state of the order is unconfirmed then redirect the user to details page and then change the state to pending. If some client would need to do some validation, then register an intermediate state between unconfirmed and pending Please suggest.

  • Nagios state transition and event handler issue

    - by Dattatray
    We are using Nagios to check duplicate processes. define service { use local-service host_name xxx service_description xxx Duplicate Processes check_interval 1 max_check_attempts 1 contact_groups admins event_handler restart-dependent-processes check_command check_procs_duplicate!2!3!2!2!2 } check_procs_duplicate checks if there are any duplicate processes and returns the state - e.g. CRITICAL. The event handler kills the duplicate processes and it's dependent processes and starts one instance of the process and dependent process. At the end of this again Nagios checks if there are any duplicate processes and sets the state accordingly - OK/WARNING/CRITICAL. The event handler takes more time to start the processes and during this time if someone manually starts the process, the state will remain in CRITICAL itself. During the next interval, Nagios will again check for duplicate processes and it will find it again CRITICAL. The event handler will not get executed now, as the previos and current both the states are CRITICAL. Any pointers about how to fix this issue?

  • Impact of Truncate or Drop Table When Flashback Database is Enabled

    - by alejandro.vargas
    Recently I was working on a VLDB on the implementation of a disaster recovery environment configured with data guard physical standby and fast start failover. One of the questions that come up was about the overhead of truncating and dropping tables. There are daily jobs on the database that truncate extremely large partitions, and as note 565535.1 explains, we knew there is an overhead for these operations. But the information on the note was not clear enough, we the additional information I've got from Senior Oracle colleagues I did compile this document "Impact of Truncate or Drop Table When Flashback Database is Enabled" that further explain the case

  • SEO - why did my google search rank drop?

    - by Brian McCarthy
    My nutrition shop websites for tampa and brandon were coming up on page one of google search results and now they have dissappeared. The 2 websites serve different markets although they are close geographically and have the same products, keywords, and layouts. Brandon, FL is considered a suburb of Tampa, FL and could be grouped into the Tampa Bay area. There's also a mirror site nutrition shop setup for orlando. Is the google search ranking drop because: 1) from a flash banner recently added on the front page 2) is the site just being re-indexed on all search engines b/c of new content? 3) is it seen as duplicate content as there are separate websites for the cities of Tampa and Brandon but with the same content? What can be done to fix this? Thanks!

  • Funnel Visualisation not showing drop out in steps

    - by cjk
    I have a site where users will follow this path (hopefully): mysite.com/entity mysite.com/entity/pay mysite.com/entity/pay/details mysite.com/entity/pay/confirmation mysite.com/entity/pay/payment mysite.com/entity/paymentsuccessful?lotsofuniquestuff The entity section could be any one of a multitude of entries, but once the user is on a journey it will stay consistent. I have a goal set up for this as a regular expression, with the match being .*PaymentSuccessful.*. This detects goal successes perfectly (as checked with data stored by the site directly). I have set the following steps within the goal: /[a-zA-Z0-9]+/pay /[a-zA-Z0-9]+/pay/details /[a-zA-Z0-9]+/pay/confirmation /[a-zA-Z0-9]+/pay/payment My funnel detects entry into the funnel (e.g. 47 users) of which say 10 complete the funnel. However, all drop offs are after the first step, even though the exist page is listed as the second step! My data also suggests users are getting further in the funnel before failing to reach the goal. What have I done wrong?

  • Expérience HTML5 : Drag & Drop de dossiers, Chrome 21 apporte une solution à l'API

    Développez un système d'upload de fichiers et dossiers similaire à l'explorateur Windows Grâce aux nouvelles API apparues avec HTML5 il est d'ores et déjà possible de créer un système d'upload de fichiers et de dossiers reprenant le fonctionnement de l'explorateur Windows ou du Finder d'OS X. Malgré une bonne compatibilité pour la fonction de Drag & Drop, le cas d'un dossier reste problématique. En effet, lorsqu'un utilisateur veut mettre en ligne un dossier en le faisant glisser à l'endroit prévu, il s'attend à ce que le dossier et tout son contenu (sous-dossiers, fichiers) soient mis en ligne. Or jusqu'à présent ...

  • Drag and Drop Team Selection

    - by davidjwest
    I have a Fantasy F1 Website, currently users select their teams using dropdown menus. It works OK but isn't as user friendly as I would like. I would like to implement a drag and drop type of system, there's jQuery code out there that would go part of the way to allowing me to do this: http://jqueryui.com/demos/draggable/ But I am not sure about how to integrate that into PHP and MySQL, my jQuery skills are limited! I'd also need to stop them spending more than a certain amount of money, each driver has a value and the teams can only spend a certain amount of money. There's also limits for example you can only pick a driver once, but you can have three different drivers. Finally, how would you decide that the user had picked their team, I don't want a submit button as that kind of defeats the object of the exercise! Thanks for any advice, I don't expect anyone to write the code for me but some pointers would be greatly appreciated.

  • how to drop down the list of options in a drop down control (COMBO BOX) in a browser

    - by anjanbacchu
    Hi All, I've known for a long time that F4 key drops down the list in a combo box(drop down) in windows applications. In I.E, the address box drops down if you press F4 anywhere in the page. This is NOT what I had expected, though. However, what I want to know is, in Windows(at least), what is the key combination that will drop down the list of a drop down control(combo box) in a web browser (say, Firefox or Chrome) ? Thank you,

  • e.Data.GetDataPresent not working in WinForms drag-and-drop handler?

    - by jnylen
    I'm trying to drag files into my application from a program called Locate32 (which is great by the way). Here is what happens: e.Data.GetFormats() {string[7]} [0]: "FileDrop" [1]: "FileNameW" [2]: "FileName" [3]: "FileNameMap" [4]: "FileNameMapW" [5]: "Shell IDList Array" [6]: "Shell Object Offsets" DataFormats.FileDrop "FileDrop" e.Data.GetDataPresent(DataFormats.FileDrop) false Why does e.Data.GetDataPresent(DataFormats.FileDrop) return false even though FileDrop is clearly one of the formats listed as "available"? Drag and drop works fine from Windows Explorer. If I do e.Data.GetData(DataFormats.FileDrop) I get a list of a bunch of filenames, as I should. Here's the code for my DragEnter handler: private void MyForm_DragEnter(object sender, DragEventArgs e) { if(e.Data.GetDataPresent(DataFormats.FileDrop)) { e.Effect = DragDropEffects.Copy; } else { e.Effect = DragDropEffects.None; } }

  • Qt 4.x: how to implement drag-and-drop onto the desktop or into a folder?

    - by Jeremy Friesner
    Hi all, I've written a little file-transfer application written in C++ using Qt 4.x ... it logs into a server, shows the user a list of files available on the server, and lets the user upload or download files. This all works fine; you can even drag a file in from the desktop (or from an open folder), and when you drop the file icon into the server-files-list-view, the dropped file gets uploaded to the server. Now I have a request for the opposite action as well... my users would like to be able to drag a file out of the server-files-list-view and onto the desktop, or into an open folder window, and have that file get downloaded into that location. That seems like a reasonable request, but I don't know how to implement it. Is there a way for a Qt application to find out the directory corresponding to where "drop event" occurred, when the icon was dropped onto the desktop or into an open folder window? Ideally this would be a Qt-based platform-neutral mechanism, but if that doesn't exist, then platform-specific mechanisms for MacOS/X and Windows (XP or higher) would suffice. Any ideas?

  • performing a javascript event without triggering that event handler

    - by bento
    In my latest code, I have an event handler for a focus on a textarea. When the user clicks on the textarea, that event-handler is triggered which sets some other DOM states based on the selected textarea. However, elsewhere in my program I want to programmatically set the focus of the textarea without triggering that event handler. I know Backbone, for instance, has a way to silently perform an action. My only pseudo-solution is to temporarily set a variable: var silence = true; And then, in my event handler, only perform the logic if silence is false. The handler is still triggered, but the logic doesn't run. Does anyone else know of better strategies for this?

  • jquery "this" binding issue on event handler

    - by clyfe
    In jquery an event hadler's binding is the event generating DOM element (this points to the dom element). In prototype to change the binding of an event handler one can use the bindAsEventListener function; How can I access both the instance and the DOM element from a event handler? Similar to http://stackoverflow.com/questions/117361/how-can-i-bind-an-event-handler-to-an-instance-in-jquery function Car(){ this.km = 0; $("#sprint").click(this.drive); //setup event handler } // event handler // in it I need to access both the clicked element // and the binding object (instance of car) Car.prototype.drive = function(){ this.km += 10; // i'd like to access the binding (but jq changes it) this.css({ left: this.km }); // also the element // NOTE that is inside this function I want to access them not elsewhere } var car = new Car();
