    I have a php file with the following code: <?php ?> <form action="" id="f1" name="f1"> <input type="button" name="preview" value="Open PDF" onclick="showPDF()" /> </form> <script type="text/javascript" src="jquery-1.4.2.min.js"></script> <script type="text/javascript"> function showPDF(){ var newwin=window.open("pdf.pdf","Window1","menubar=no,width=430,height=360,toolbar=no"); newwin.print(); } </script> It opens up a popup window with pdf file inside it BUT fails to open the print dialog box.

Can anybody provide me a solution to this

  • Getting the height of a div after setting it to auto in IE

    - by Dominic Godin
    Hi, I'm writing some JavaScript that changes the size of some content. To do this I need to know the size of a div within my content. If I have the following html: <div id="wrapper"> ... other stuff ... <div id="inner" style="height:400px">Some text in here</div> ... other stuff ... </div> And the following JavaScript: $('#inner').height('auto'); var height = $("#wrapper").height(); In FireFox and Chrome the height variable increases as the inner div expands to fit all the text. In IE this stays the same. I guess it doesn't redraw the div straight away. Anybody know how to get the new correct height in IE? Cheers

  • jQuery > reset popup window 's x and y relative to icon that launched the window

    - by Scott B
    I have a jQuery jPicker colorpicker that is bound to an input text field and opens onclick of a small picker.gif icon. The problem I'm having is that (1) The colorpicker that opens does not appear to be positioned according to the x/y position of the picker.gif (it opens far away from the click point) and (2) The colorpicker does not seem to be aware of the viewport's scroll position (the top of the colorpicker is partially hidden at the top of the window). I'd like to use jQuery to reposition the colorpalette (1) Based on the x/y position of the input that its bound to and (2) reset it's top position based on the viewport's visible Y position. Here is the script where I am creating a new jPicker and binding it to my input text fields for header and sidebar... $('#myHeaderColor').jPicker ( {}, function(color) { $(this).val(color.get_Hex()); }, function(color) { $(this).val(color.get_Hex()); } ); $('#mySidebarColor').jPicker ( {}, function(color) { $(this).val(color.get_Hex()); }, function(color) { $(this).val(color.get_Hex()); } );

  • Why is FF on OS X loosing jQuery-UI in click event handler?

    - by Jean-François Beauchamp
    In a web page using jQUery 1.7.1 and jQUery-UI 1.8.18, if I output $.ui in an alert box when the document is ready, I get [object Object]. However when using Firefox, if I output $.ui in a click event handler, I get 'undefined' as result. With other browsers (latest versions of IE, Chrome and Safari), the result is still [object Object] when clicking on the link. Here is my HTML Page: <!doctype html> <html> <head> <title></title> <script src="Scripts/jquery-1.7.1.js" type="text/javascript"></script> <script src="Scripts/jquery-ui-1.8.18.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function () { alert($.ui); // ALERT A $(document).on("click", ".dialogLink", function () { alert($.ui); // ALERT B return false; }); }); </script> </head> <body> <a href="#" class="dialogLink">Click me!</a> </body> </html> In this post, I reduced to its simplest form another problem I was having described here: $(this).dialog is not a function. I created a new post for the sake of clarity, since the real question is different from the original one now that pin-pointed where the problem resided. UPDATE: IF I replace my alerts with simply alert($); I get this result for alert A: function (selector, context) { return new jQuery.fn.init(selector, context, rootjQuery); } and this one for alert B: function (a, b) { return new d.fn.init(a, b, g); } This does not make sense to me, although I may not be understanding well enough what $ is... UPDATE 2: I can only reproduce this problem using Firefox on OS X. On Firefox running on Windows 7, everything is fine.

  • ListBox content does not resize when window is made smaller

    - by DamonGant
    I'm using .NET 4.0 (not .NET 4.0 CP) and have run into this kinda unique issue. I created a ListBox to display bound elements, first off here is (a part) of my XAML. <Grid Grid.Row="2" Background="#EEEEEE"> <Border Margin="6,10,10,10" BorderBrush="#666666" BorderThickness="1"> <ListBox ItemsSource="{Binding}" Name="appList" BorderThickness="0" HorizontalContentAlignment="Stretch" HorizontalAlignment="Stretch"> <ItemsControl.ItemTemplate> <DataTemplate> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="80" /> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <Border Grid.Column="0" Margin="5" BorderThickness="3" CornerRadius="2" BorderBrush="Black" HorizontalAlignment="Left" VerticalAlignment="Top" x:Name="ItemBorder"> <Image Width="64" Height="64" Source="{Binding Path=IconUri}" Stretch="UniformToFill" /> </Border> <StackPanel Margin="0,5,5,5" Grid.Column="1" Orientation="Vertical" HorizontalAlignment="Stretch"> <TextBlock FontSize="18" Text="{Binding Path=DisplayName}" /> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> <ColumnDefinition Width="60"/> </Grid.ColumnDefinitions> <ProgressBar Grid.Column="0" Height="24" HorizontalAlignment="Stretch" IsIndeterminate="{Binding Path=IsDiscovering}" Value="{Binding Path=PercentageDownloaded}" /> <TextBlock Grid.Column="1" HorizontalAlignment="Center" VerticalAlignment="Center"><TextBlock x:Name="percentageDownloaded" /><TextBlock x:Name="percentageMeter">%</TextBlock></TextBlock> </Grid> </StackPanel> </Grid> <DataTemplate.Triggers> <DataTrigger Binding="{Binding Path=IsDiscovering}"> <DataTrigger.Value>True</DataTrigger.Value> <Setter TargetName="percentageDownloaded" Property="Text" Value="N/A" /> <Setter TargetName="percentageMeter" Property="Visibility" Value="Collapsed" /> </DataTrigger> <DataTrigger Binding="{Binding Path=IsDiscovering}"> <DataTrigger.Value>False</DataTrigger.Value> <Setter TargetName="percentageDownloaded" Property="Text" Value="{Binding Path=PercentageDownloaded}" /> <Setter TargetName="percentageMeter" Property="Visibility" Value="Visible" /> </DataTrigger> </DataTemplate.Triggers> </DataTemplate> </ItemsControl.ItemTemplate> </ListBox> </Border> </Grid> Sizing the window up stretches the ListBox content just fine, but when I size it down, it retains it's width and spawns vertical scrollbars.

  • jQuery Dialog theme not being applied

    - by Tim
    I'm using jquery-1.4.2.min.js and jquery-ui-1.8.1.custom.min.js. According to Firebug, both minimized scripts have been loaded. They both appear in the dropdown list on Firebug's Scripts tab. The dialog is launching, but there's no background and so the text below it shows through, and there's no "window" stuff at all, no titlebar, no X button. Just the floating/draggable text with a -close- link at the top left corner. I was under the impression from reading these pages http://jqueryui.com/demos/dialog/ http://jqueryui.com/themeroller/ that the UI theme-driven appearance would be automatically applied to the dialog when it was invoked using this barebones call: $('#dialog').dialog() I would be grateful for suggestions on how to troubleshoot this. Thanks

  • Adding a new row in between rows in a grid view.

    - by SARAVAN
    I have an ASP .net grid view. It has some template columns like a command button, a text box, and a dropdown control. When I click the command button, a new row needs to be inserted below the current row (from where I hit the command button). If I have rows 1 and 2 and I hit the command button in row1 a new row needs to be inserted between rows 1 and 2 Now in the new row I should be able to select values from dropdown and enter some value in a text box and finally hit my save button. (Which should work fine as I am expecting) The grid view is bound to some data source say for instance a datatable for now. Oneway that I could think about is when Command button is clicked, I can add a new row to the datatable in my server side code and rebind the grid. But I am not sure that, from a UI perspective how I can make sure that the new row goes exactly below the row from where I hit the command button. Any thoughts or comments?

  • Calling back a functions value

    - by Jason Kelly
    I need your help, I cannot, for the life of me, figure this out. I've had my head wrapped around it only to no avail. Ideally, i'd like to setup two functions. 1 function: select_date() to interact with the user to select a date from the jQuery Date picker. If the dialog is closed then return as null. Then a second function: test() to check wether or not a date was picked/selected.' Here's my delema, when the function test() is executed, an alert box pops up and says "undefined" which means, I never get to select a date and it always being "undefined" I dont see what I am doing wrong here and everything seems logical to me. <!DOCTYPE html> <html> <head> <link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.21/themes/base/jquery-ui.css" rel="stylesheet" type="text/css"/> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.js"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.21/jquery-ui.js"></script> <script type="text/javascript"> function select_date() { var sdate $('#dd').dialog({ autoOpen: true, modal: true, overlay: { opacity: 0.5, background: 'black' }, title: "title", height: 265, width: 235, draggable: false, resizable: false }); $('#d1').datepicker({ onSelect: function () { $("#dd").dialog("close"); } }); return sdate } function test() { var x = select_date() alert(x) } </script> <style type="text/css"> #d1 {font-size:64%;} </style> </head> <body> <div id="dd"> <div id="d1"> </div> </div> <a href="javascript:test()">test</a> </body> </html>

    I would need to know how to handle the intent between tabs. For example, I have a tab activity with two tabs. First on content is a text view. another one is a map view. When i click that text view it redirects to the tab2. it can be easily achieved by setCurrentTab(1) or setCurrentTabByTag("tab2") methods. But i want to pass lat and long values to that Map Activity to drop pin. What is the better way to use intents or getter/setter in java? What do you prefer? if your answer is "Intents". How?

  • Why jQuery selector can't work but getElementById works in this scenario?

    - by Stallman
    Here is the HTML: <html> <head> <script type="text/javascript" src="jquery-1.7.2.min.js"></script> <script type="text/javascript" charset="utf-8" src="jquery-1.7.2.js"></script> <script type="text/javascript" src="access.js"></script> </head> <body> <button id="trigger"></button> <img id= "testElement" style= "position: absolute; border-color: white; top:340px; left:615px;" width="34px" height= "34px" /> </body> </html> And the access.js file is: $(document).ready( function(){ $('#trigger').click(function(){ $('#testElement').src="success.png"; //THIS WON'T WORK. document.getElementById('testElement').src= "success.png"; //BUT THIS WORKS. }); }); I know that if I use $, the return object is a jQuery object. It's not the same as getElementById. But why the jQuery selector can't work here? I need the jQuery object to make more operations like "append/style"... Thanks. UPDATE Too much correct answers appear at almost the same time... Please give more explanations to let me decide who I should give the credit, thanks!!! Sorry for my poor understanding of your correct answer... I just want more detail. Are all the attribute nodes(src/width/height...) not the property of jQuery object? So does the jQuery selector only select DOM Element Node like ? Thank you! 3. List item
