  • "Undoing deletes" in webapplication?

    - by Industrial
    Hi everybody, I have seen more and more of the websites that offers a undo option after pressing a delete button. How is the logic done behind the button? Is the item deleted by javascript and "dissapears" from the users screen and a scheduled delete added, that gives the user time to undo it or how does it work? What are the other options to offer the users an undo feature?

  • Does this incorporate JavaScript closures?

    - by alex
    In trying to learn JavaScript closures, I've confused myself a bit. From what I've gathered over the web, a closure is... Declaring a function within another function, and that inner function has access to its parent function's variables, even after that parent function has returned. Here is a small sample of script from a recent project. It allows text in a div to be scrolled up and down by buttons. var pageScroll = (function() { var $page, $next, $prev, canScroll = true, textHeight, scrollHeight; var init = function() { $page = $('#secondary-page'); // reset text $page.scrollTop(0); textHeight = $page.outerHeight(); scrollHeight = $page.attr('scrollHeight'); if (textHeight === scrollHeight) { // not enough text to scroll return false; }; $page.after('<div id="page-controls"><button id="page-prev">prev</button><button id="page-next">next</button></div>'); $next = $('#page-next'); $prev = $('#page-prev'); $prev.hide(); $next.click(scrollDown); $prev.click(scrollUp); }; var scrollDown = function() { if ( ! canScroll) return; canScroll = false; var scrollTop = $page.scrollTop(); $prev.fadeIn(500); if (scrollTop == textHeight) { // can we scroll any lower? $next.fadeOut(500); } $page.animate({ scrollTop: '+=' + textHeight + 'px'}, 500, function() { canScroll = true; }); }; var scrollUp = function() { $next.fadeIn(500); $prev.fadeOut(500); $page.animate({ scrollTop: 0}, 500); }; $(document).ready(init); }()); Does this example use closures? I know it has functions within functions, but is there a case where the outer variables being preserved is being used? Am I using them without knowing it? Thanks Update Would this make a closure if I placed this beneath the $(document).ready(init); statement? return { scrollDown: scrollDown }; Could it then be, if I wanted to make the text scroll down from anywhere else in JavaScript, I could do pageScroll.scrollDown(); I'm going to have a play around on http://www.jsbin.com and report back

  • Stretch panel with splitter

    - by user1153896
    I want to implement a basic WPF layout with three panels and two splitters (Horizontal and Vertical splitter). Two panels on the left and on the bottom has to be callapsable and one panel has to stretch accordingly. Here is a simple XAML: <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="*"/> <ColumnDefinition Width="5"/> <ColumnDefinition Width="*"/> </Grid.ColumnDefinitions> <StackPanel Background="Aqua" Grid.Column="0" Name="leftPanel" > <TextBlock FontSize="35" Foreground="#58290A" TextWrapping="Wrap">Left Hand Side</TextBlock> </StackPanel> <GridSplitter Grid.Column="1" HorizontalAlignment="Stretch"/> <Grid Grid.Column="2" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <Grid.RowDefinitions> <RowDefinition Height="*" /> <RowDefinition Height="5" /> <RowDefinition Height="*" /> </Grid.RowDefinitions> <StackPanel HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <Label Content="... Clien Area .. Has to Stretch vertically and horizontally" Margin="10"></Label> <Button Click="LeftButton_Click" Margin="10">Close Left Panel</Button> <Button Click="BottomButton_Click" Margin="10">Close Bottom Panel</Button> </StackPanel> <GridSplitter Grid.Row="1" Background="Gray" HorizontalAlignment="Stretch"/> <ListBox Grid.Row="2" Background="Violet" Name="bottomPanel"> <ListBoxItem>Hello</ListBoxItem> <ListBoxItem>World</ListBoxItem> </ListBox> </Grid> </Grid> and codebehind: private void LeftButton_Click(object sender, RoutedEventArgs e) { leftPanel.Visibility = (leftPanel.Visibility == System.Windows.Visibility.Visible)? System.Windows.Visibility.Collapsed : System.Windows.Visibility.Visible; } private void BottomButton_Click(object sender, RoutedEventArgs e) { bottomPanel.Visibility = (bottomPanel.Visibility == System.Windows.Visibility.Visible) ? System.Windows.Visibility.Collapsed : System.Windows.Visibility.Visible; } This code doesn't work as expected :(. Any WPF experts around? to suggest a solution for having Client Area (stretched) and splitter at the same time? DockPanel will work perfectly, but I need splitter! Thanks.

  • Dynamically refresh JTextArea as processing occurs?

    - by digiarnie
    I am trying to create a very simple Swing UI that logs information onto the screen via a JTextArea as processing occurs in the background. When the user clicks a button, I want each call to: textArea.append(someString + "\n"); to immediately show up in the UI. At the moment, the JTextArea does not show all log information until the processing has completed after clicking the button. How can I get it to refresh dynamically?

    I'm creating a child window within the main window. I assigned these styles to the child window: WS_CHILDWINDOW | WS_VISIBLE | WS_VSCROLL | WS_HSCROLL | WS_SIZEBOX | WS_CAPTION The child window I get has a caption and a resizable border. However there's no close button in the caption, and the caption/border of the child window is not transparent (I'm using the aero theme in windows 7). Here is the screen snap: How to add close button to the caption? How can I make the caption/border transparent?

  • facebook integration for sites

    - by disappearedng
    Hi everyone, AFAIK, the following are not possible for now: (Assuming we have user A which has allowed us all permissions:) Send a message to a A's friend get A's friends email Aside from the obvious "Like" button, what are the ways that an app can leverage facebook's graph API to increase traffic flow? I find the Like button to be more of a broadcasting mechanism. I was wondering what are the ways that I can specifically tell user B, whom is a friend of User A, that he/she should come check out my site. Many thanks

  • Add jquery link to returned text...

    - by Jerry
    Hi all I am trying to add two jquery plugins files to my application. When a user triggers my ajax event, the server will return text with a form button. The plugins (a jquery calendar) will work when the user clicks the form button inside the returned text . I believe I have to add the link inside the return text instead of the main page to let the code work, but not sure how to do this. I am giving out my code and need you experts opinions. Thanks. My main page html //required jquery plugins ...didn't work if I add them in the main application. <script type="text/javascript" src="JS/date.js"></script> <script type="text/javascript" src="JS/datePicker.js"></script> <script type="text/javascript" src="JS/selectWeek.js"></script> <div id="gameInfo"> //return text will be displayed here. </div> My returned text ...part of it.... <form> <div id=returnDiv> // the form input will be added here when a user clicks #addMatch button... </div> <tr> <td><input type="button" id="addMatch" name="addMatch" value="Add Match"/> </td> </tr> </form> My jquery $("#addMatch").live('click', function(){ //the code below will create a calender when a user click the link...I am not sure //where I should add my two jquery plugins link... $("#returnDiv").html("<td><input type='text' size='6' class='date-pick dp-applied'"+ "name='date'><a style='color:white;' class='dp-choose-date' title='Choose Date'"+ "href='#'>Date</a></td>"; return false; }); I hope I explain my question well. +1 to any reply...:D
