  • How to pass checkbox array to Java from jsp

    - by eddy
    Hi, I'd like to know if there's any way to send data to the server for the selected rows using the checkboxes I've put on those rows? I mean , how can I send only the data of those selected rows to the server? Here's the html code I use: <table> <thead> <tr class="tableheader"> <td width="10%"></td> <td width="30%">Vehicle</td> <td width="40%">Driver</td> <td width="10%">Mileage</td> </tr> </thead> <tbody> <c:forEach items="${list}" var="item"> <tr> <td align="center"> <input type="checkbox" name="selectedItems" value="c:out value="${item.numberPlate}"/>"/> </td> <td align="left"><c:out value="${item.numberPlate}"/></td> <td align="left"><c:out value="${item.driver.fullName}" /></td> <td align="left"><input type="text" name="mileage" value="" /></td> </tr> </c:forEach> </tbody> </table> I really hope you can give some guidance on this. Thanks in beforehand.

  • SIFR, JAVASCRIPT & PHP - How to apply SIFR to dynamically loaded content.

    - by user311039
    Well here's the problem: I have a PHP index page which uses show/hide layers javascript. I am using the on menu.click function to show and hide content relevant to each menu. On.click all divs are hidden except the content for that menu item , which fades in. The content relating to each menu item are displayed within separate DIVS. The property is applied to all the text within all the divs. See: http://jobe-group.com/jobeco/uk/2010live/dynamic/content/index.php# The trouble is that SIFR only appears to be applied to the displayed on.load when the page is first loaded. When this is hidden and the other s shown through the "show" function they load in classic CSS fonts without the SIFR applied. Is this unavoidable with the SIFR setup. Or am I not calling the divs properly. I have set the SIFR to apply to the selector and indeed it works fine on the for the displayed on load. It doesn't work for the within other . In theory I would think its possible to load the SIFR on all divs on page.load even if those divs are presently visibility:hidden. What's the verdict on this? Hope someone can help. Cheers, John

  • Webinvoke to POST JSON with ajax call

    - by G-Man
    This is my first time that I an using WCF Service with Knockout. I want to POST an entire view model as a JSON object with an ajax call. This is the error message that I get: Endpoints using 'UriTemplate' cannot be used with 'System.ServiceModel.Description.WebScriptEnablingBehavior' I have noticed that some developers send each value as a parameter which I feel is unnecessary especially if you work with a big object. This is my WCF method: [OperationContract] [WebInvoke(UriTemplate = "AddNewEvent?newEvent", Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)] public bool AddNewEvent(Models.DAL_CRMEvents newEvent) { Entities.CRMEntities dbCRM = new Entities.CRMEntities(); //Models.CRMEvents crmEvent = new Models.CRMEvents(); Entities.Event crmEvent = new Entities.Event(); crmEvent.EventDateCreated = Convert.ToDateTime(newEvent.DateCreated); crmEvent.EventActive = true; crmEvent.EventDescription = newEvent.Description; crmEvent.EventDate = Convert.ToDateTime(newEvent.Date); crmEvent.EventTimeStart = TimeSpan.Parse(newEvent.TimeStart); crmEvent.EventTimeEnd = TimeSpan.Parse(newEvent.TimeEnd); crmEvent.EventAllDay = newEvent.AllDay; dbCRM.AddToEvent(crmEvent); return true; } This is my ajax function function SaveEvent (data) { var s = { newEvent: ko.mapping.toJS(data) } alert(data.AllDay()); $.ajax({ type: "POST", url: "../Services/CRMDataService.svc/AddNewEvent", data: JSON.stringify(s), contentType: "application/json; charset=utf-8", dataType: "JSON", success: function (result) { alert(result); }, error: function (jqXHR, textStatus, errorThrown) { if (textStatus == "error" && errorThrown != "") { var n = noty({ text: errorThrown, type: 'warning', dismissQueue: false, modal: true, layout: 'center', theme: 'defaults', callback: { } }) } } }) }

  • WPF DataGrid populating blank rows on TreeView's SelectedItemChanged

    - by jes9582
    When my DataGrid populates on the TreeView's SelectedItemChanged event it finds the objects and creates the rows accordingly but the rows populate with no text or are just blank. So I know it is finding my objects but it is not displaying them properly. Does anyone see where I made an error or suggest any changes or fixes? Thank you in advance! Here is the CSharp code that is setting the DataGrid's ItemsSource (I am using .dbml and LINQ with Lambda expressions): dgSystemSettings.ItemsSource = (tvSystemConfiguration.SelectedItem as SYSTEM_SETTINGS_GROUP).SYSTEM_SETTINGS_NAMEs.Join(ssdc.SYSTEM_SETTINGS_VALUEs, x => x.SSN_ID, y => y.SSV_SSN_ID, (x, y) => new { SYSTEM_SETTINGS_NAME = x, SYSTEM_SETTINGS_VALUE = y }); And here is the .xaml: <DataGrid Name="dgSystemSettings" AutoGenerateColumns="False" Height="447" Width="513" DockPanel.Dock="Right" ItemsSource="{Binding}" VerticalAlignment="Top" Margin="10,10,0,0"> <DataGrid.Columns> <DataGridTextColumn x:Name="colDisplayName" Header="Name" Binding="{Binding SSN_DISPLAY_NAME}"></DataGridTextColumn> <DataGridTextColumn x:Name="colValue" Header="Value" Binding="{Binding SSV_VALUE}"></DataGridTextColumn> </DataGrid.Columns> </DataGrid>

  • ASP.NET: I'm getting strange output when styling a Label control...

    - by pkiyan
    .labelOne { border-width:thin; border-style:solid; border-color:Red; background-color:Silver; } <asp:Label ID="Label1" runat="server" CssClass="labelOne"> <h1>Hello world</h1> </asp:Label> <br /><br /> <asp:Label ID="Label2" runat="server" BorderColor="Black" BorderStyle="Solid" BorderWidth="1px" BackColor="Silver"> <h1>Hello world</h1> </asp:Label> Hello. In the code sample above I have 2 Label controls with their contents set to an h1 header tag. The first Label is styled using css, and the second with the Label's inline properties (both Labels have identical styling). But the first Label doesn't output properly, it's border is broken. If I replace the first Label's markup with plain "Hello world" text it renders properly, but it breaks again when I use markup. Can someone explain why this is happening?

  • Can an ASP.NET user control determine its context or its parent .aspx file

    - by John Galt
    Is it possible for a user control to determine its "context" or its parent .aspx page in some way? Right now I have a user control that is declared on a typical .aspx page as follows: <%@ Register TagPrefix="uc1" TagName="ManageTitle" Src="../UserControls/ManageTitle.ascx" %> The user control currently emits a textbox as follows: <asp:textbox id="txtTitle" runat="server" MaxLength="60" ToolTip="Describe the item with a short pithy title - most important keywords first"/> The page_load for this .ascx file is currently like this: Me.txtTitle.Text = SetPageTitle() While some places in this web app need this (i.e. a textbox where end-user can type a "title"), I have other places where I want to show the "title" information in a "read-only" way. For example, rather than a textbox, I could use a label control or a textbox with Enabled="false" to prevent data entry. I suppose I could clone this small .ascx file and append a suffix to its name like _RO.ascx or something but I am wondering what the best approach would be. In short, can a user control get some sort of "context" from the page that declares it or is there an altogether better way to accomplish this sort of thing? Thank you.

  • Why does this tooltip appear *below* a transclucent form?

    - by Daniel Stutzbach
    I have an form with an Opacity less then 1.0. I have a tooltip associated with a label on the form. When I hover the mouse over the label, the tooltip shows up under the form instead of over the form. If I leave the Opacity at its default value of 1.0, the tooltip correctly appears over the form. However, my form is obviously no longer translucent. ;-) I'm testing on an XP system with .NET 3.5. If you don't see this problem on your system, let me know what operating system and version of .NET you have. I have tried manually adjusting the position of the ToolTip with SetWindowPos() and creating a ToolTip "by hand" using CreateWindowEx(), but the problem remains. This makes me suspect its a Win32 API problem, not a problem with the Windows Forms implementation that runs on top of Win32. Why does the tooltip appear under the form, and, more importantly, how can I get it to appear over the form where it should? Here is a minimal program to demonstrate the problem: using System; using System.Windows.Forms; public class Form1 : Form { private ToolTip toolTip1; private Label label1; [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form1()); } public Form1() { toolTip1 = new ToolTip(); label1 = new Label(); label1.Location = new System.Drawing.Point(105, 127); label1.Text = "Hover over me"; label1.AutoSize = true; toolTip1.SetToolTip(label1, "This is a moderately long string, " + "designed to be very long so that it will also be quite long."); ClientSize = new System.Drawing.Size(292, 268); Controls.Add(label1); Opacity = 0.8; } }

  • Can't get gravity to work with RMagick and 'caption'

    - by mph
    I'm using RMagick 2.12.2 with ImageMagick 6.5.6-10 on Snow Leopard. I'm trying to put captions on a collection of photos, and I'm getting the caption to work (i.e. it appears on the image), but I can't get the gravity parameter to work correctly. No matter what I set it to, I end up with some variation on NorthGravity. For instance: Setting it to SouthWestGravity gives me NorthWestGravity. Setting it to SouthEastGravity gives me NorthEastGravity. Setting it to CenterGravity gives me NorthGravity. In other words, I can't get the caption to come down off the top of the image. I'd consider using "annotate," but I need "caption" so the lengthy caption text for each image will wrap. What am I doing wrong? Here's the code: #!/usr/bin/env ruby require "rubygems" require "yaml" require "RMagick" include Magick base_dir = "/Users/mike/Desktop/caption_test" photo_log = File.open("#{base_dir}/photo_log.yaml" ) YAML::load_documents(photo_log) do |doc| caption = doc["photo-caption"] filename = doc["file"] canvas = ImageList.new.from_blob(open("#{base_dir}/#{filename}") { |f| f.read } ) canvas << Magick::Image.read("caption:#{caption}") { self.gravity = SouthWestGravity self.size = "#{canvas.first.columns}" self.font = "Helvetica Neue" self.pointsize = 12 self.background_color = "#fff" }.first canvas.flatten_images.write("#{base_dir}/images/#{filename}") end

  • AndEngine: Black screen when using LayoutGameActivity

    - by Lemuel Hogben
    I used to use SimpleBaseGameActivity for my app and everything was ok, but now I want to add some ads into the app, so I tried to use LayoutGameActivity. But I get the screen completely black and I don't know why. That's my code: public class AcGame extends LayoutGameActivity { [...] @Override protected int getLayoutID() { return R.layout.ad; } @Override protected int getRenderSurfaceViewID() { return R.id.layout_render; } @Override public EngineOptions onCreateEngineOptions() { [...] return new EngineOptions(true, ScreenOrientation.PORTRAIT_FIXED, resolution, camera); } @Override public void onCreateResources(OnCreateResourcesCallback pOnCreateResourcesCallback) throws Exception { createResources(); pOnCreateResourcesCallback.onCreateResourcesFinished(); } @Override public void onCreateScene(OnCreateSceneCallback pOnCreateSceneCallback) throws Exception { pOnCreateSceneCallback.onCreateSceneFinished(createScene()); } @Override public void onPopulateScene(Scene pScene, OnPopulateSceneCallback pOnPopulateSceneCallback) throws Exception { pOnPopulateSceneCallback.onPopulateSceneFinished(); } And that's my layout: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="top" android:id="@+id/layout_ad" > <Button android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="Ad Sample"/> </LinearLayout> <org.andengine.opengl.view.RenderSurfaceView android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" android:id="@+id/layout_render" /> </LinearLayout> When I'm trying to debug, I can see that EngineOptions are creating, but no one of the LayoutGameActivity's methods was called (onCreateResources, onCreateScene or onPopulateScene). Can someone tell me what I've missed?

  • Do not get the rootLayoutContainer in a Fragment (Android 3.0 Preview)

    - by Hawk66
    Hello, I'm currently getting into the fragment API of the Android 3.0 Preview and have built the following minimal coding: I have an Activty, which shall embed Fragment(s), which is currently implemented like this: public class Cockpit extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.cockpit); } public static class InfoFragment extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment ViewGroup infoFragmentRoot = (ViewGroup) getActivity().findViewById( R.id.infoFragmentRoot) ; return inflater.inflate(R.id.infoFragment, container, false); } } } The corresponding layout of the activity: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <fragment android:name="test.android.ui.cockpit.Cockpit$InfoFragment" android:id="@+id/infoFragment" android:layout_weight="1" android:layout_width="10dp" android:layout_height="match_parent" > <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="12dp" android:id="@+id/infoFragmentRoot" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> </LinearLayout> </fragment> Now, I do not understand why the ViewGroup container in the onCreateView() in the internal class InfoFragment is a nullpointer, nor do I understand, why ViewGroup infoFragmentRoot = (ViewGroup) getActivity().findViewById( R.id.infoFragmentRoot) ; returns also null. Thanks for feedback.

  • Multiple marker icons, how to add to google mashup

    - by user351189
    I have created a Google maps mashup, where with a bit of input, I have managed to have a sidebar that links to a video icon/marker that then opens up an info window showing virtual tours. I would, however, like to put different coloured marker icons on the map depending on the category that the video is in. This would be easy enough to do, but my page is made up of a mixture of J-Query and JavaScript all calling to the individual flash files. Could someone help me with the code for adding extra marker icons for different categories? Here is the code: So, after the intial 'var camera;' point, there comes this: function addMarker(point, title, video, details) { var marker = new GMarker(point, {title: title, icon:camera}); GEvent.addListener(marker, "click", function() { if (details) { marker.openInfoWindowTabsHtml([new GInfoWindowTab("Video", video), new GInfoWindowTab("More", details)]); } else { marker.openInfoWindowHtml(video); } }); Then further down, is the code for calling the individual marker image. I would like to add another image to this list - would I start out by calling the new object 'camera-red.image' or something similar? function initialize() { if (GBrowserIsCompatible()) { map = new GMap2(document.getElementById("mapDiv")); map.setCenter(new GLatLng(51.52484592590448, -0.13345599174499512), 17); map.setUIToDefault(); var uclvtSatMapType = createUclVTSatMapType() map.addMapType(uclvtSatMapType); map.setMapType(uclvtSatMapType); camera = new GIcon(G_DEFAULT_ICON); camera.image = "ucl-video.png"; camera.iconSize = new GSize(32,37); camera.iconAnchor = new GPoint(16,35); camera.infoWindowAnchor = new GPoint(16,2); addMarkersToMap(); } The actual map can be found here: link text Thanks.

  • How do I stop Chrome from yellowing my site's input boxes?

    - by davebug
    Among other text and visual aids on a form submission, post-validation, I'm coloring my input boxes red to signify the interactive area needing attention. On Chrome (and for Google Toolbar users) the auto-fill feature re-colors my input forms yellow. Here's the complex issue: I want auto-complete allowed on my forms, as it speeds users logging in. I am going to check into the ability to turn the autocomplete attribute to off if/when there's an error triggered, but it is a complex bit of coding to programmatically turn off the auto-complete for the single effected input on a page. This, to put it simply, would be a major headache. So to try to avoid that issue, is there any simpler method of stopping Chrome from re-coloring the input boxes? [edit] I tried the !important suggestion below and it had no effect. I have not yet checked Google Toolbar to see if the !important attribute woudl work for that. As far as I can tell, there isn't any means other than using the autocomplete attribute (which does appear to work).

  • Loading Javascript through an AJAX load through jQuery??

    - by Jason Axelrod
    I have an javascript that I place into a page using the code below. What the code does is place an object/embed code into a webpage. Simple javascript loader to a NicoVideo movie <script type="text/javascript" src="http://ext.nicovideo.jp/thumb_watch/sm13154955?w=640&h=395"></script> This works great in a webpage. But what if I want to load this javascript into a page using AJAX? This no longer works for the obvious reasons, you would need to eval the script in order to get it to run. However, I have no idea how to do this. I am using jQuery on my page; so keep that in mind. I have tried the following code, but it doesn't seem to work through AJAX, or even in a normal page load environment. <script>$.getScript("http://ext.nicovideo.jp/thumb_watch/sm13154955?w=640&h=395");</script> Any ideas on how I would get this to work?

  • Fixing merge conflicts?

    - by user291701
    I have two remote branches, "grape" and "master". I'm currently on "grape". Now I switch to "master": git checkout master Now I want to pull all changes from "grape" into "master" - is this the way to do it?: git merge origin grape It's my understanding that git will then pull all the current state of the remote branch "grape" into my local copy of "master". It will try to auto-merge for me. If there are conflicts, the files in conflict will have some conflict text actually injected into the file. I then have to go into those files, and delete the chunk I don't want (essentially telling git how to merge these files). For each file in conflict, do I add and commit the changes again?: git add problemfile1.txt git commit -m "Fixed merge conflict." git add problemfile2.txt git commit -m "Fixed another merge conflict." ... after I've fixed all the merge conflicts like above, do I just push to "master" again to finish up the process?: git push origin master or is there something else we need to do when we get into this conflict state? Thank you

  • JQuery Delegate and using traveral options in function

    - by Brian
    I am having trouble figuring out how to use the JQuery delegate function to do what I require. Basically, I need to allow users to add Panels (i.e. divs) to a form dynamically by selecting a button. Then when a user clicks a button within a given Panel, I want to be able to to something to that Panel (like change the color in this example). Unfortunately, it seems that references to the JQuery traversing functions don't work in this instance. Can anybody explain how to achieve this effect? Is there anyway to bind a different delegate to the each panel as its added. $('.addPanels').delegate('*', 'click', function() { $(this).parent.css('background-color', 'black'); $('.placeholder').append('Add item'); }); <div class="addPanels"> <div class="panel"> <a href="#" class="addLink">Add item</a> text</div> <div class="placeholder"/> </div> </div>

  • The post->success->data variable is empty..

  • iPhone app. Creating a custom UIView that contains UITextField and UIButton.

    - by Dmitry Burchik
    Hi all. I am new to iPhone programming. And I have an issue. I need to create a custom user control that I will add to my UIScrollView dinamically. The control has an UITextField and an UIButton. See the code below: #import <UIKit/UIKit.h> @interface FieldWithValueControl : UIView { UITextField *txtTagName; UIButton *addButton; } @property (nonatomic, readonly) UITextField *txtTagName; @property (nonatomic, readonly) UIButton *addButton; @end #import "FieldWithValueControl.h" #define ITEM_SPACING 10 #define ITEM_HEIGHT 20 #define SWITCHBOX_WIDTH 100 #define SCREEN_WIDTH 320 #define ITEM_FONT_SIZE 14 #define TEXTBOX_WIDTH 150 @implementation FieldWithValueControl @synthesize txtTagName; @synthesize addButton; - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { // Initialization code txtTagName = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, TEXTBOX_WIDTH, ITEM_HEIGHT)]; txtTagName.borderStyle = UITextBorderStyleRoundedRect; addButton = [UIButton buttonWithType:UIButtonTypeContactAdd]; [addButton setFrame:CGRectMake(ITEM_SPACING + TEXTBOX_WIDTH, 0, ITEM_HEIGHT, ITEM_HEIGHT)]; [addButton addTarget:self action:@selector(addButtonTouched:) forControlEvents:UIControlEventTouchUpInside]; [self addSubview:txtTagName]; [self addSubview:addButton]; } return self; } - (void)addButtonTouched:sender { UIButton *button = (UIButton*)sender; NSString *title = [button titleLabel].text; } - (void)drawRect:(CGRect)rect { // Drawing code } - (void)dealloc { [txtTagName release]; [addButton release]; [super dealloc]; } @end In my code I create an object of that class and add it to scrollView on form. FieldWithValueControl *newTagControl = (FieldWithValueControl*)[[FieldWithValueControl alloc] initWithFrame:CGRectMake(ITEM_SPACING, currentOffset + ITEM_SPACING, 0, 0)]; [scrollView addSubview:newTagControl]; The control looks fine, but if I click to the textbox or to the button nothing happens. Keyboard doesn't appear, the button is not clickable etc.

  • Should I be using Expression Blend to design really dynamic UIs?

    - by Robert Rossney
    My company's product is, at its core, a framework for developing metadata-driven UIs. I don't know how to characterize it less succinctly than that, and hope I won't need to for purposes of this question, but we'll see. I've been trying to come up to speed on WPF, and have been building UI prototypes here and there, and recently I decided to see if I could use Expression Blend to help with the design of these UIs. And I'm pretty mystified at this point. It appears to me as though Expresssion Blend is designed with the expectation that you already know all of the objects that are going to be present in the UI at design time. But our program generates these object dynamically at runtime. For instance, a data row might be presented in a horizontal StackPanel containing alternating TextBlocks (for captions) and TextBoxes (for data fields). The number of these objects depends on metadata about the number of columns in the data row. I can, pretty readily, write code that runs through a metadata record and populates a StackPanel dynamically, setting up the binding of all of the controls to properties in either the data or metadata. (A TextBox's Width might be bound to metadata, while its Text is bound to data.) But I can't even begin to figure out how to do something like this in Expression Blend. I can manually create all these controls, so that I have a set of controls that I can apply styles to and work out the visual design of the app, but it's really a pain to do this. I can write code that goes through my data model and emits XAML for all these controls, I suppose, and then copy and paste it. But I'm going to feel really stupid if it turns out there a way to do this sort of thing in Expression Blend and I've dropped back and punted because I'm too dim to figure out the right way to think of it. Is this enough information for someone to try formulating an answer?

Key presses (arrows or 1-5) should have no effect (i.e. The events should be cancelled so that the number never changes from the initial default "3"). [I have separate working code for IE too]. Many thanks to anyone who can make it work? <html> <head> <title>Test</title> <script type='text/JavaScript'> function stop(evt) {evt.preventDefault(); evt.stopPropagation(); }; </script> </head> <body> <select onkeydown='stop(event);' onkeypress='stop(event);'> <option>1</option> <option>2</option> <option selected="selected">3</option> <option>4</option> <option>5</option> </select> </body> </html>

  • Can't unwrap Optional.None tableviewcell

    - by Mathew Padley
    I've a table view that has a custom table view cell in it. My problem is that when i try and assign a value to a variable in the custom table view cell I get the stated error. Now, I think its because the said variable is not initialised, but its got me completely stumped. This is the custom table cell: import Foundation import UIKit class LocationGeographyTableViewCell: UITableViewCell { //@IBOutlet var Map : MKMapView; @IBOutlet var AddressLine1 : UILabel; @IBOutlet var AddressLine2 : UILabel; @IBOutlet var County : UILabel; @IBOutlet var Postcode : UILabel; @IBOutlet var Telephone : UILabel; var location = VisitedLocation(); func Build(location:VisitedLocation) -> Void { self.location = location; AddressLine1.text = "test"; } } My cell for row at index path is: override func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! { var addressCell = tableView.dequeueReusableCellWithIdentifier("ContactDetail") as? LocationGeographyTableViewCell; if !addressCell { addressCell = LocationGeographyTableViewCell(style: UITableViewCellStyle.Value1, reuseIdentifier: "ContactDetail"); } addressCell!.Build(Location); return addressCell; } As I say I'm completely baffled, the Build function calls the correct function in the tableviewcell. Any help will be gratefully appreciated. Ta

  • [solved] Why can't I dynamically add lines to a HTML table using JavaScript in Internet Explorer?

    - by karlthorwald
    After many hours of debugging I am tired, maybe you can help me now to solve this: In a new Firefox it works, in my Internet Explorer 6 or 7 it doesn't: <html> <head> <script type="text/javascript"> function newLine() { var tdmod = document.createElement('td'); tdmod.appendChild(document.createTextNode("dynamic")); var tr = document.createElement('tr'); tr.appendChild(tdmod); var tt = document.getElementById("t1"); tt.appendChild(tr); } </script> </head> <body> <a href="#" onclick="newLine()">newLine</a> <table id="t1" border="1"> <tr> <td> static </td> </tr> </table> </body> You can klick on the link and new lines should be added to the table. Try it here: http://dl.dropbox.com/u/1508092/iejs.html#
