  • Positioning DIV element at center of screen

    - by iSumitG
    I want to position a DIV (or a TABLE) element at the center of screen irrespective of screen size. In other words, the space left on 'top' and 'bottom' should be equal and space left on 'right' and 'left' sides should be equal. How to do it? Note: I prefer a complete CSS solution, but if is not possible without Javascript then using Javascript is also fine. I am trying the following but it is not working: <body> <div style="top:0px; border:1px solid red;"> <table border="1" align="center"> <tr height="100%"> <td height="100%" width="100%" valign="middle" align="center"> We are launching soon! </td> </tr> </table> </div> </body> Note: It is either way fine if the DIV element (or TABLE) scrolls with the website or not. Just want it to be at center when page loads.

  • Javascript to fire event when a key pressed on the Ajax Toolkit Combo box.

    - by Paul Chapman
    I have the following drop down list which is using the Ajax Toolkit to provide a combo box <cc1:ComboBox ID="txtDrug" runat="server" style="font-size:8pt; width:267px;" Font-Size="8pt" DropDownStyle="DropDownList" AutoCompleteMode="SuggestAppend" AutoPostBack="True" ontextchanged="txtDrug_TextChanged" /> Now I need to load this up with approx 7,000 records which takes a considerable time, and effects the response times when the page is posted back and forth. The code which loads these records is as follows; dtDrugs = wsHelper.spGetAllDrugs(); txtDrug.DataValueField = "pkDrugsID"; txtDrug.DataTextField = "drugName"; txtDrug.DataSource = dtDrugs; txtDrug.DataBind(); However if I could get an event to fire when a letter is typed instead of having to load 7000 records it is reduced to less than 50 in most instances. I think this can be done in Javascript. So the question is how can I get an event to fire such that when the form starts there is nothing in the drop down, but as soon as a key is pressed it searches for those records starting with that letter. The .Net side of things I'm sure about - it is the Javascript I'm not. Thanks in advance

  • Why is this Javascript that writes out a Google Ad not displaying properly on the iPhone?

    - by Dave M G
    I have this Javacsript code that checks to see if there is a DIV named "google-ad", and if there is, it writes in a the necessary code to display the Google Ad. This works great in browsers like Firefox, Chrome, Safari on Mac, and Android. However, when I bundle this code with Adobe's Phonegap Build, and deploy it to iPhones, it behaves strangely. It launches a browser window displaying just the Google Ad alone. In order to keep using my app, every time I change a page and a new Google Ad is loaded, I have to close the browser window to get back to the app. Why is this code launching browser windows outside of my Phonegap app on iPhone? if(document.getElementById("google-ad") && document.getElementById("google-ad") !== null && document.getElementById("google-ad") !== "undefined") { if(userStatus.status == 0) { document.getElementById("centre").style.padding = "137px 0 12px 0"; document.getElementById("header-container").style.margin = "-138px 0 0 0"; document.getElementById("header-container").style.height = "132px"; document.getElementById("header-username").style.top = "52px"; document.getElementById("google-ad").style.height = "50px"; document.getElementById("google-ad").style.width = "320px"; document.getElementById("google-ad").style.backgroundColor = "#f0ebff"; document.getElementById("google-ad").style.display = "block"; window["google_ad_client"] = 'ca-pub-0000000000000000'; window["google_ad_slot"] = "00000000"; window["google_ad_width"] = 320; window["google_ad_height"] = 50; window.adcontainer = document.getElementById('google-ad'); window.adhtml = ''; function mywrite(html) { adhtml += html; adcontainer.innerHTML = adhtml; }; document.write_ = document.write; document.write = mywrite; script = document.createElement('script'); script.src='http://pagead2.googlesyndication.com/pagead/show_ads.js'; script.type='text/javascript'; document.body.appendChild(script); }

  • Is it possible to guarantee a unique id for multiple items using the same id variable at a point in

    - by Scarface
    First of all, do not be overwhelmed by the long code, I just put it for reference...I have a function that preg_replaces content and puts it in a jquery dialog box with a matching open-link. For example, if there is a paragraph with two matches, they will be put inside two divs, and a jquery dialog function will be echoed twice; one for each div. While this works for one match, if there are multiple matches, it does not. I am not sure how to distribute unique ids at a point in time for each of the divs and matching dialog open-scripts. Keep in mind, I removed the preg replace function since it kind of complicates the problem. If anyone has any ideas, they will be greatly appreciated. <?php $id=uniqid(); $id2=uniqid(); echo "<div id=\"$id2\"> </div>"; ?> $.ui.dialog.defaults.bgiframe = true; $(function() { $("<?php echo"#$id2"; ?>").dialog({hide: 'clip', modal: true ,width: 600,height: 350,position: 'center', show: 'clip',stack: true,title: 'title', minHeight: 25, minWidth: 100, autoOpen: false}); $('<?php echo"#$id"; ?>').click(function() { $('<?php echo"#$id2"; ?>').dialog('open'); }) .hover( function(){ $(this).addClass("ui-state-hover"); }, function(){ $(this).removeClass("ui-state-hover"); } ).mousedown(function(){ $(this).addClass("ui-state-active"); }) .mouseup(function(){ $(this).removeClass("ui-state-active"); }); });

  • Programmatic Text Wrapping in TextView

    - by Andrew
    I'm working on a custom widget for my application to replicate the look of a Preference button for layouts. The issue is the 'summary' text wont wrap when it hits the right wall of the view. One of the goals I'm trying to keep is that this widget is completely made from java with no xml attributes. here's what the widget looks like at the moment: http://dl.dropbox.com/u/56017670/Screenshot_2012-09-05-17-22-45.png notice that the middle two don't wrap the text but the text obviously runs right off the edge of the widget below is the code I'm using to create the text view. public void setSummary(String summary) { if (!TextUtils.isEmpty(summary)) { if (mSummaryView == null) { mSummaryView = new TextView(mContext); mSummaryView.setTextSize(14); mSummaryView.setTextColor(mContext.getResources().getColor( android.R.color.tertiary_text_dark)); addView(mSummaryView); } mSummaryView.setText(summary); mSummaryView.setVisibility(View.VISIBLE); } else { if (mSummaryView != null) { mSummaryView.setVisibility(View.GONE); } } mSummaryText = summary; } and here is the code I'm using to layout mSummaryView mSummaryView.layout( mPreferencePadding + mIconWidth, centerVertical + (mCombinedTextHeight / 2) - mSummaryHeight, width - mPreferencePadding, centerVertical + (mCombinedTextHeight / 2)); I've tried to add mSummaryView.setSingleLine(false); along with quite a few other tricks but they all ended in the same way.

  • Creating transparent gridlines

    - by Rob Penridge
    I'm trying to get the chart's gridlines to be transparent but it doesn't seem to be supported: http://support.sas.com/documentation/cdl/en/grstatug/63302/HTML/default/viewer.htm#n1f71f6e9v037an1jy274v66z4r1.htm I'm doing to try and blend the gridlines with the chart background color (which in my code can change between colors) which would make the gridlines subtle rather than jarring when background colors change. Here is my code: ** ** TAKE THE DEFAULT STYLE BEING USED. MODIFY IT SO THAT ** GRAPH GRIDLINES WILL BE GREEN AND MOSTLY TRANSPARENT *; proc template; define style my_style; parent = styles.default; style GraphGridLines from GraphGridLines / contrastcolor=green transparency=.05; end; run; ** ** LAYOUT TEMPLATE FOR A SIMPLE SERIES CHART *; proc template; define statgraph mychart; begingraph; layout overlay / wallcolor=black xaxisopts=(display=(line) griddisplay=on) yaxisopts=(display=(line)) ; seriesplot x=name y=height / lineattrs=(color=white); endlayout; endgraph; end; run; ** ** PLOT SAMPLE DATA USING CUSTOM STYLE AND CHART LAYOUT WE JUST DEFINED *; ods graphics / width=640 height=640 ; ods html style=my_style; proc sgrender data=sashelp.class template=mychart; run; ods html close; Is there another way to achieve this effect by blending the green color with the background color?

  • Javascript problem with iframe that's hidden before loaded

    - by Aistina
    I have a page that contains an iframe that gets loaded using Javascript: index.html <iframe id="myFrame" width="800" height="600" style="display: none;"></iframe> <div id="loader"><!-- some loading indicator --></div> <script type="text/javascript"> function someFunction() { var myFrame = document.getElementById('myFrame'); var loader = document.getElementById('loader'); loader.style.display = 'block'; myFrame.src = 'myFrame.html'; myFrame.onload = function() { myFrame.style.display = 'block'; loader.style.display = 'none'; }; } </script> The page that gets loaded in the iframe contains some Javascript logic which calculates the sizes of certain elements for the purposes of adding a JS driven scrollbar (jScrollPane + jQuery Dimensions). myFrame.html <div id="scrollingElement" style="overflow: auto;"> <div id="several"></div> <div id="child"></div> <div id="elements"></div> </div> <script type="text/javascript"> $(document).load(function() { $('#scrollingElement').jScrollPane(); }); </script> This works in Chrome (and probably other Webkit browsers), but fails in Firefox and IE because at the time jScrollPane gets called, all the elements are still invisble and jQuery Dimensions is unable to determine any element's dimensions. Is there a way to make sure my iframe is visible before $(document).ready(...) gets called? Other than using setTimeout to delay jScrollPane, which is something I definitely want to avoid.

  • Cocos2d - smooth sprite movement in tile map RPG

    - by Lendo92
    I've been working on a 2-D Gameboy style RPG for a while now, and the game logic is mostly all done so I'm starting to try to make things look good. One thing I've noticed is that the walking movement / screen movement is a little bit choppy. Technically, it should work fine, but either it seems to be having some quirks, either due to taking up a lot of processing power or just timing inconsistencies between moving the screen and moving the sprite. To move the sprite, once I know where I want to move it, I call: tempPos.y += 3*theHKMap.tileSize.width/5; id actionMove = [CCMoveTo actionWithDuration:0.1 position:tempPos]; id actionMoveDone = [CCCallFuncN actionWithTarget:self selector:@selector(orientOneMove)]; [guy runAction:[CCSequence actions:actionMove, actionMoveDone, nil]]; [self setCenterOfScreen:position]; Then, in orientOneMove, I call: [self.guy setTexture:[[CCTextureCache sharedTextureCache] addImage:@"guysprite07.png"]]; //the walking picture-I change texture back at the end of the movement id actionMove = [CCMoveTo actionWithDuration:0.15 position:self.tempLocation2]; id actionMoveDone = [CCCallFuncN actionWithTarget:self selector:@selector(toggleTouchEnabled)]; [guy runAction:[CCSequence actions:actionMove, actionMoveDone, nil]]; The code for the concurrently running setCenterOfScreen:position method is: id actionMove = [CCMoveTo actionWithDuration:0.25 position:difference]; [self runAction: [CCSequence actions:actionMove, nil, nil]]; So the setCenterOfScreen moves the camera in one clean move while the guy moving is chopped into two actions to animate it (which I believe might be inefficient.) It's hard to tell what is making the movement not perfectly clean from looking at it, but essentially the guy isn't always perfectly in the center of the screen -- during movement, he's often times a pixel or two off for an instant. Any ideas/ solutions?

  • How to change button background color depending on bound command canexecute ??

    - by LaurentH
    Hi, I Have a ItemTemplate in which is a simple button bound on a command, which can be executable or not depending on some property. I'd like the color of this button's background to change if the command isn't executable. I tried several methods, but I can't find anyway to do this purely in XAML (I'm doing this in a study context, and code behind isn't allowed). Here's my code for the button : <Button x:Name="Dispo" HorizontalAlignment="Center" Margin="0" VerticalAlignment="Center" Width="30" Height="30" Grid.Column="2" Grid.Row="0" Command="{Binding AddEmpruntCommandModel.Command}" CommandParameter="{Binding ElementName='flowCars', Path='SelectedItem'}" vm:CreateCommandBinding.Command="{Binding AddEmpruntCommandModel}" > <Button.Style> <Style TargetType="{x:Type Button}"> <Style.Triggers> <Trigger Property="IsEnabled" Value="True"> <Setter Property="Button.Background" Value="Green"/> </Trigger> <Trigger Property="IsEnabled" Value="False"> <Setter Property="Button.Background" Value="Red"/> </Trigger> </Style.Triggers> </Style> </Button.Style> </Button>

  • Submit to open up a popup window and carry through input data

    - by zac
    Hi, I have a input box on one page that on submit opens a new page with a longer form and the first field is populated with what was entered from the previous pages input box. So on page 1 there is this code: <form action="sign-up.php"> <input type="text" name="email" value="sign up for email" onFocus="clearText(this)" onBlur="clearText(this)" style="float: left;"> <input value='Submit' /> </form> Then on the sign-up page the receiving form grabs the string out of the url //<!-- Begin function getParams() { var idx = document.URL.indexOf('?'); if (idx != -1) { var tempParams = new Object(); var pairs = document.URL.substring(idx+1,document.URL.length).split('&'); for (var i=0; i<pairs.length; i++) { nameVal = pairs[i].split('='); tempParams[nameVal[0]] = nameVal[1]; } return tempParams; } } var params = getParams(); // End --> I would like to keep all of this functionality but it have it occur in a popup. I added this function to the submit: function myPopup() { window.open( "sign-up.php", "myWindow", "status = 1, height = 300, width = 300, resizable = 0" ) and the form becomes <form> <input type="text" name="email" value="sign up for email" onFocus="clearText(this)" onBlur="clearText(this)" style="float: left;"> <input onClick="myPopup()" value='Submit' /> </form> But it no longer appends the input data to the url string. Anyone have any ideas on how I can accomplish this?

  • How to calculate the normal of points on a 3D cubic Bézier curve given normals for its start and end points?

    - by Robert
    I'm trying to render a "3D ribbon" using a single 3D cubic Bézier curve to describe it (the width of the ribbon is some constant). The first and last control points have a normal vector associated with them (which are always perpendicular to the tangents at those points, and describe the surface normal of the ribbon at those points), and I'm trying to smoothly interpolate the normal vector over the course of the curve. For example, given a curve which forms the letter 'C', with the first and last control points both having surface normals pointing upwards, the ribbon should start flat, parallel to the ground, slowly turn, and then end flat again, facing the same way as the first control point. To do this "smoothly", it would have to face outwards half-way through the curve. At the moment (for this case), I've only been able to get all the surfaces facing upwards (and not outwards in the middle), which creates an ugly transition in the middle. It's quite hard to explain, I've attached some images below of this example with what it currently looks like (all surfaces facing upwards, sharp flip in the middle) and what it should look like (smooth transition, surfaces slowly rotate round). Silver faces represent the front, black faces the back. Incorrect, what it currently looks like: Correct, what it should look like: All I really need is to be able to calculate this "hybrid normal vector" for any point on the 3D cubic bézier curve, and I can generate the polygons no problem, but I can't work out how to get them to smoothly rotate round as depicted. Completely stuck as to how to proceed!

  • Google Bar Chart Time Label Interval

    - by Alex Angelini
    Hi I am using Google Bar Chart through the visualization API on my site: http://code.google.com/apis/visualization/documentation/gallery/imagebarchart.html And my x-axis is time, and every time interval is a time of day in the format (HH:MM) Here is my code for the graph: <script type="text/javascript" src="https://www.google.com/jsapi"></script> <script type="text/javascript"> %s google.load("visualization", "1", {packages:["imagebarchart"]}); google.setOnLoadCallback(drawChart); function drawChart() { var data = new google.visualization.DataTable(); data.addColumn('string', 'Date'); data.addColumn('number', 'Amount'); data.addRows({{Rows}}); %s var chart = new google.visualization.ImageBarChart(document.getElementById('chart_div')); chart.draw(data, {width: 900, height: 340, min: 0, isVertical:true, legend:'none'}); } </script> The rows of data are added later using a templating engine, but that is the jist of my chart. Because I have added my time variable as 'string' I cannot use the valueLabelsInterval option to only show every 4 labels. Because I can't do that the labels overlap and look ugly. Is there any other way to only show every other time label or every 4th one, I read through the docs but could not see how to do it. Any help would be greatly appreciated thanks

  • Can I change the binding source to another source in XAML?

    - by No hay Problema
    Hi guys, I want to do a very simple thing, can you point me on the right direction? I want to change the source in XAML to another object source, let me put you an example: I have a Listview, bound to a "Model A", it has many properties, but one is called "Total". This property is not shown on the View Each ListviewItem has its own source (ItemsSource), BUT, one of the fields should show "Total" from "Model A" Caveat: I am implementing MVVM, so the "Model A" is assigned as a VM DataSource, XAML knows nothing about it. So, in my perfect world the XAML should look like this: <GridViewColumn Header="Total" Width="150"> <GridViewColumn.CellTemplate> <DataTemplate> <Label Content="{Binding Source=<The source of LISTVIEW> Path=Total}"/> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> I have tried RelativeSource but that points me to the XAML object, I want the source of it, is it possible? Thanks

  • Problem with loading a PNG image in JApplet.

    - by Bruce
    Hi there, I'm trying to load a PNG image from JAR file when running JApplet. The file is, I think, loaded properly - there are no errors. However it is not displayed. img.png is placed in the same directory as MainClass.java file.

What am I missing/doing wrong? Thanks in advance for the reply!

It is only updated when I press the button which brings up a message box. /// <summary> /// Interaction logic for Window1.xaml /// </summary> public partial class Window1 : Window, INotifyPropertyChanged { String _testText = new StringBuilder("One").ToString(); public string TestText { get { return _testText; } set { if (value != _testText) { _testText = value; OnPropertyChanged("TestText"); } } } public Window1() { InitializeComponent(); myGrid.DataContext = this; } private void OnPropertyChanged(string property) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(property)); } } public event PropertyChangedEventHandler PropertyChanged; private void onKeyUp(object sender, KeyEventArgs e) { if (e.Key != System.Windows.Input.Key.Enter) return; System.Diagnostics.Trace.WriteLine(TestText); } private void button1_Click(object sender, RoutedEventArgs e) { MessageBox.Show(TestText); } } Window XAML: Window x:Class="VerificationTest.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300" KeyUp="onKeyUp" TextBox XAML: TextBox Name="myTextBox" Text="{Binding TestText}" Button XAML: Button Name="button1" Click="button1_Click"

  • Bookmarklet, js injection and popup issue

    - by Neewok
    I'm currently writing a bookmarklet that loads and executes a remote js file by appending a new <script> tag in the current window, like so : javascript:(function() { if(typeof __bml_main != "undefined") return __bml_main.init(); var s= document.createElement('script'); s.type= 'text/javascript'; s.src= 'http://127.0.0.1:8000/media/bookmarklet.js'; void(document.body.appendChild(s)); })(); My bookmarklet needs to perform some dom manipulations in order to extract data from the page being viewed, and then to open a new popup to list them. The thing is : if I want to bypass pop-up blockers, I can't open my new window from the injected script. I need to open it right from the beginning in the bookmarklet code, and to access it later when needed. I've tried to do somehting like this : javascript:var my_popup = window.open('http://127.0.0.1:8000/resources/manage/new/', 'newResourcePopup',config='height=200,width=400,toolbar=no,menubar=no,scrollbars=no,resizable=no,location=no,directories=no,status=no'); (function() { // script injection (...) })(); but if I then try to access my_popup from my remotely loaded script, most browsers will throw a security warning and won't let me access the Window object. This is understandable since the script is not from the same domain than the displayed page, but I'm kind of stuck... A solution would be to use a div overlay, but I'd really prefer to open a window in this case. Any hints ?

  • how to get large pictures from photo album via facebook graph api

    - by Nav
    I am currently using the following code to retrieve all the photos from a user profile FB.api('/me/albums?fields=id,name', function(response) { //console.log(response.data.length); for (var i = 0; i < response.data.length; i++) { var album = response.data[i]; FB.api('/' + album.id + '/photos', function(photos) { if (photos && photos.data && photos.data.length) { for (var j = 0; j < photos.data.length; j++) { var photo = photos.data[j]; // photo.picture contain the link to picture var image = document.createElement('img'); image.src = photo.picture; document.body.appendChild(image); image.className = "border"; image.onclick = function() { //this.parentNode.removeChild(this); document.getElementById(info.id).src = this.src; document.getElementById(info.id).style.width = "220px"; document.getElementById(info.id).style.height = "126px"; }; } } }); } }); but, the photos that it returns are of poor quality and are basically like thumbnails.How to retrieve larger photos from the albums. Generally for profile picture I use ?type=large which returns a decent profile image but the type=large is not working in the case of photos from photo albums and also is there a way to get the photos in zip format from facebook once I specify the photo url as I want users to be able to download the photos.
