  • How to hide Amazon webstore default toolbar with Prototype?

    - by melaos
    Hi Guys, after playing around this morning, i've found that there's this default chunk of html code in the amazon webstore which will add a toolbar on top of the page. the html looks like below: <td id="wba_logo_bg"> <table class="logo" border="0" cellpadding="0" cellspacing="0" width="100%"> <tbody><tr><td align="left"></td> <td class="wba_account" style="padding: 5px;" align="right" valign="top"> <table border="0" cellpadding="0" cellspacing="0"> <form action="#" id="searchForm" method="get" name="searchForm"></form> <tbody><tr><td class="wba_account_link"> <a xmlns:xhtml="http://www.w3.org/1999/xhtml" class="myAccountNav" href="#" onclick="return false;">home</a></td> <td class="myAccountDots"></td> <td class="wba_account_link"><a class="myAccountNav" href="#" onclick="return false;">view cart</a></td> <td class="myAccountDots"></td><td class="wba_account_link"><a class="myAccountNav" href="#" onclick="return false;">my account</a></td> <td class="myAccountDots"></td><td class="wba_account_link"><a class="myAccountNav" href="#" onclick="return false;">order status</a></td> <td><img src="pageEditor_files/1_pixel.gif" hspace="7"></td> <td><input name="keyword" tabindex="1" type="text"></td> <td><img alt="Search" class="wba_search_btn" onclick="return false;" onkeyup="if (13==event.keyCode) searchForm.submit();" src="pageEditor_files/btn_search.gif" style="cursor: pointer;" tabindex="2" title="Search" hspace="3"> </td></tr></tbody> </table> </td></tr></tbody> </table> </td> and thus far i was able to use prototype to find those with the class name of wba_account_link and hide them via the codes below: function hideAmazonToolbar() { $("wba_logo_bg").hide(); }//end function but what i really want to do is preferably to hide the whole tbody instead, but with my limited prototype skills, i don't really know how to do this. can anybody point me to the right resources on how to get this done? thanks! EDIT Went higher up and apparently there's a td with an id, and solve it using prototype hide function! man, i love javascript framework :) thanks :)

  • jQuery val not working properly in Chrome

    - by Mircea
    I have a simple jQuery function: $('#selectable1 span').live('mousedown', function() { var ff = $(this).css("font-family"); $("#family").val(ff); }); When a span element is clicked (mousedown) an input (#family) gets its font family value. It works in FireFox but in Chrome it works only for font families composed from only one word. Georgia will work but Times New Roman will now. You can see the code here: http://jsfiddle.net/aLaGa/ or live at http://www.typefolly.com What is wrong with this? Thanx

  • JQuery UI Dialog query dialog DOM

    - by Travis
    The following simply loads a jquery-ui dialog from an external html file. $('#showdialog').click(function(e) { var div = $('<div>loading...</div>'); div.dialog({ modal: true, open: function() { div.load('anotherpage.html'); } }); e.preventDefault(); }); After the DOM loads from the external html file, I'd like to interrogate it with JQuery. For example, supposing anothorpage.html had a bunch of anchors on it, I'd like to wire up click handlers for them when it loads into the dialog. Any ideas?

  • Insert xelements using LINQ Select?

    - by Simon Woods
    I have a source piece of xml into which I want to insert multiple elements which are created dependant upon certain values found in the original xml At present I have a sub which does this for me: <Extension()> Public Sub AddElements(ByVal xml As XElement, ByVal elementList As IEnumerable(Of XElement)) For Each e In elementList xml.Add(e) Next End Sub And this is getting invoked in a routine as follows: Dim myElement = New XElement("NewElements") myElement.AddElements( xml.Descendants("TheElements"). Where(Function(e) e.Attribute("FilterElement") IsNot Nothing). Select(Function(e) New XElement("NewElement", New XAttribute("Text", e.Attribute("FilterElement").Value)))) Is it possible to re-write this using Linq syntax so I don't need to call out to the Sub AddElements but could do it all in-line Many Thx Simon

  • WPF Animation of border width

    - by Dave Perry
    I've got a dockpanel on my ui as follows; <DockPanel> <Border DockPanel.Dock="Top">Header</Border> <Border DockPanel.Dock="Bottom">My footer</Border> <Border DockPanel.Dock="Left">Menu</Border> <Border>Content</Border> </DockPanel> What I want to do is to have a storyboard animation to show / hide the Menu on the left-hand side. I've got my border to increase the width when it has loaded but I want a way to close / reopen it. I need a button somewhere but I want this to trigger the animation in the border control rather than itself. Ideally I was thinking of something like the Toolbox / Server Explorer in visual studio. Does anyone have any pointers / examples for getting started? Thanks

  • Allowing threads from python after calling a blocking i/o code in a python extension generated using

    - by SS
    I have written a python extension wrapping an existing C++ library live555 (wrapping RTSP client interface to be specific) in SWIG. The extension works when it is operated in a single thread, but as soon as I call the event loop function of the library, python interpreter never gets the control back. So if I create a scheduled task using threading.Timer right before calling the event loop, that task never gets executed once event loop starts. To fix this issue, I added Py_BEGIN_ALLOW_THREADS and Py_END_ALLOW_THREADS macros manually in the SWIG auto generated wrapper cxx file around every doEventLoop() function call. But now, I want to do the same (i.e. allow threads) when SWIG generates the code itself and not to change any code manually. Has anyone done something similar in SWIG? P.S. - I would also consider switching to any other framework (like SIP) to get this working. I selected SWIG over any other technology is because writing SWIG interface was really very easy and I just had to include the existing header files.

  • How to create a closure and pass in variable length argument list?

    - by Jian Lin
    We can create a closure p by capturing the arguments in the scope in the following code: var p = function() { }; if (typeof(console) != 'undefined' && console.log) { p = function() { console.log(arguments); }; } but the arguments are passed like an array to console.log, instead of passed one by one as in console.log(arguments[0], arguments[1], arguments[2], ... Is there a way to expand the arguments and pass to console.log like the way above? Note that p = console.log; works well in Firefox and IE 8 but not on Chrome.

  • FxCop giving a warning on private constructor CA1823 and CA1053

    - by Luis Sánchez
    I have a class that looks like the following: Public Class Utilities Public Shared Function blah(userCode As String) As String 'doing some stuff End Function End Class I'm running FxCop 10 on it and it says: "Because type 'Utilities' contains only 'static' ( 'Shared' in Visual Basic) members, add a default private constructor to prevent the compiler from adding a default public constructor." Ok, you're right Mr. FxCop, I'll add a private constructor: Private Utilities() Now I'm having: "It appears that field 'Utilities.Utilities' is never used or is only ever assigned to. Use this field or remove it." Any ideas of what should I do to get rid of both warnings?

  • Can't access dojo object property using string variable

    - by Kareem
    I am retrieving a json associative array using a dojo xhrGet request. The data comes back just fine, however I need the app to be able to display the keys and their properties (or values) without knowing the keys beforehand. So, I do the following: function getData() { dojo.xhrGet( { url: "ytd_process.php", handleAs: "json", load: function(response) { for (var key in response) { dojo.byId("boxes").innerHTML+="<div id=\"box\">"+key+":"+response.key+"</div>"; } console.dir(response); // Dump it to the console } }); }; The keys are retrieved and displayed on the page, but the response.key returns undefined. I know the syntax is correct because if I replace .key with an actual key value it will display correctly. It appears it doesn't like a string as the key. Any help or advice would be greatly appreciated. Thank you.

  • CakePHP dynamic element

    - by Logic Artist
    I am trying to create a message-board type element in a CakePHP app. This element will be displayed on all pages and views that use a particular layout. I want it to display all the messages in the model, then show the add form when a link is clicked, then return to the updated message list when submitted. All this without affecting the current view/page. I have my message model/controller/index set up, with a message board element that requests the index action. This works fine. However I am perplexed about how to return back to the original page/action from which the link was clicked. I can't use $this-referer() because that will link back to the add() action; what I want rather is to link to the page/view before that. Any general pointers on how to achieve something like this?

  • Doing ajax with Jquery.

    - by user272899
    I have been loading content with ajax and all works fine. Here is my code $(document).ready(function() { //Load a-z.php //Timestamp resolves IE caching issue var tsTimeStamp= new Date().getTime(); $.post('../../includes/categories/a-z.php', {action: "post", time: tsTimeStamp}, function(data){ $('#moviescontainer').html(data).slideDown('slow'); }); return true; }); My data inside a-z.php requires Javascript for it's content and when I load a-z.php onto my page the javascript doesn't work. I am quessing that I need to link the relevant files to a-z.php and then load it via ajax. Doesn't this kind of defeat the object of ajax?? That means that I will be loading the js files on the main page and then loading them again when I ajax a-z.php I hope I made some sense.

  • Red5 RTMP Streaming

    - by SyntaxError
    I'm very new to RTMP streaming and am seeking help. Just enough to get me started. I have been Googling for about 5-7 hours now and still cannot determine my answer! The documentation of Red5 is limited and cannot find any support at all! Even similar questions to mine are unanswered on stackoverflow :( My questions are: Why can't I simply place an .mp3 inside red5's server root and play it? To serve a simple MP3 file over RTMP. Do I need to write a Java application? If so, any pointers? To make matters worse, I have little to none Java experience. Please help ST.

  • Assignment to None

    - by Joel
    Hello, I have a function which returns 3 numbers, e.g.: def numbers(): return 1,2,3 usually I call this function to receive all three returned numbers e.g.: a,b,c=numbers() However, I have one case in which I only need the first returned number. I tried using: a, None None = numbers() But I receive "SyntaxError: assignment to None". I know, of course, that i can use the first option I mentioned and then not use "b" and "c", but only "a". However, this seems like a "waste" of two vars and feels like wrong programming. Any ideas? Thanks, Joek

  • C# Reset a property

    - by Jeff
    I'm writing a Clone function for a non serializeable object.For most objects I don't care if they are shallow copied as I won't be making any changes to them. I start with a MemberwiseClone and this copies all the values and few objects like configuration dictionary over just fine but they are pointers. EAVEntity newClone = (EAVEntity) this.MemberwiseClone(); newClone.EntityStorageID = Guid.NewGuid(); newClone.Controls.Clear(); So how do I reset a pointer so I can make them not point at the same location?

  • Select points on a map

    - by Dave Hanna
    I am just beginning design work on a problem that I'm sure has been solved before. In a web based application, I need to: a) present a map b) place a set of points (map-pins) on the map c) allow the user at his browser to draw a simple closed curve on the map with his mouse d) send the path of that curve back to the server e) on the server, select from the set of points those that are within the closed curve. What are the best API's to use for this problem? (I know I can and will do more research with Google, but I'm figuring there is probably someone who has done this that can give me some pointers to narrow my search space.) Thanks.

  • Rails Google Maps integration Javascript problem

    - by JZ
    I'm working on Rails 3.0.0.beta2, following Advanced Rails Recipes "Recipe #32, Mark locations on a Google Map" and I hit a road block: I do not see a google map. My @adds view uses @adds.to_json to connect the google maps api with my model. My database contains "latitude" "longitude", as floating points. And the entire project can be accessed at github. Can you see where I'm not connecting the to_json output with the javascript correctly? Can you see other glairing errors in my javascript? Thanks in advance! My application.js file: function initialize() { if (GBrowserIsCompatible() && typeof adds != 'undefined') { var map = new GMap2(document.getElementById("map")); map.setCenter(new GLatLng(37.4419, -122.1419), 13); map.addControl(new GLargeMapControl()); function createMarker(latlng, add) { var marker = new GMarker(latlng); var html="<strong>"+add.first_name+"</strong><br />"+add.address; GEvent.addListener(marker,"click", function() { map.openInfoWindowHtml(latlng, html); }); return marker; } var bounds = new GLatLngBounds; for (var i = 0; i < adds.length; i++) { var latlng=new GLatLng(adds[i].latitude,adds[i].longitude) bounds.extend(latlng); map.addOverlay(createMarker(latlng, adds[i])); } map.setCenter(bounds.getCenter(),map.getBoundsZoomLevel(bounds)); } } window.onload=initialize; window.onunload=GUnload; Layouts/adds.html.erb: <script src="http://maps.google.com/maps?file=api&amp;v=2&amp;sensor=true_or_false&amp;key=ABQIAAAAeH4ThRuftWNHlwYdvcK1QBTJQa0g3IQ9GZqIMmInSLzwtGDKaBQvZChl_y5OHf0juslJRNx7TbxK3Q" type="text/javascript"></script> <% if @adds -%> <script type="text/javascript"> var maps = <%= @adds.to_json %>; </script> <% end -%>

  • Problems with Linked List in C

    - by seePhor
    Hey everyone, I am new to C and I am working on an XOR linked list for a project. I have most of the code done, but I can't seem to get the delete function of the list to work properly. It seems able to delete some numbers, but not any number you pass into the function. Could anyone experienced with C take a look and possibly point out where I went wrong? I have been working on this for a while now and have not had much luck and I have started over 3 times :( Any help is much appreciated. Thank you. You can see my first attempt of code here. I can only post one link, so if you would like to see my second attempt, just tell me so and I can email it to you or something. Thank you for your time.

  • GetDC() DllImport for x64 apps

    - by devdept
    If you make a little research on the internet you'll see many DLLImport styles for this user32.dll function: HDC GetDC(HWND hWnd); The question is: what type is more appropriate for .NET x64 apps (either compiled with the Platform target as AnyCPU on a x64 machine or specifically as x64)? IntPtr for example grows to a size of 8 on a x64 process, can this be a problem? Is uint more appropriate than Uint64? What is the size of the pointers this function uses when used in a x64 process? The DLL is called user32.dll does it work as 32bit or 64bit on a x64 operating system? [DllImport("user32.dll",EntryPoint="GetDC")] public static extern IntPtr GetDC(IntPtr hWnd); public static extern uint GetDC(uint hWnd); public static extern int GetDC(int hWnd); Thanks!

  • How to override the behavior of Input type="file" Browse button?

    - by jay sean
    Hi All, I need to change the locale/language of the browse button in input type="file" We have a special function to change the locale of any text to the browser language such as en-US es-MX etc. Say changeLang("Test"); // This will display test in Spanish if the browser // locale is es-MX What I need to do is to change the language of the browse button. Since it is not displayed, I can't code it like changeLang("Browse..."); That's why I need to get the code of this input type and override so that I can apply my function to Browse text. It will be appreciated if you can give a solution for this. Thanks! Jay...

  • How do you draw a line from one corner of the stage to the other?

    - by George Edison
    I am completely perplexed. I asked this question and it (any mentioned solution) doesn't seem to be working at all. All I want is to draw a line from one corner to the other. Here again is the link to the SWF file I have (it's embedded in an HTML document): test.html Here is the source: package { import flash.display.Sprite; import flash.events.Event; public class Main extends Sprite { public function Main():void { if (stage) init(); else addEventListener(Event.ADDED_TO_STAGE, init); } private function init(e:Event = null):void { removeEventListener(Event.ADDED_TO_STAGE, init); // entry point graphics.clear(); graphics.lineStyle(10, 0x000000); graphics.moveTo(0, 0); graphics.lineTo(stage.stageWidth, stage.stageHeight); } } } It just doesn't work! The line goes from somewhere offscreen to about the middle of the stage. What on earth am I doing wrong?

  • Flash AS3 - Display an error if the XML if incorrect

    - by ongoingworlds
    Hi, I'm creating a flash application which loads in some XML which is generated dynamically from the CMS. I want to display an error in case the XML file isn't formatted correctly. When I test this with incorrectly formatted XML, it will just get to the line myXML = XML(myLoader.data); and then just bomb out. How can I catch the error, display a message to the user, but the flash program to continue as normal. var myXMLURL:URLRequest = new URLRequest(XMLfile); var myLoader:URLLoader = new URLLoader(myXMLURL); myLoader.addEventListener(Event.COMPLETE, xmlLoaded); myLoader.addEventListener(IOErrorEvent.IO_ERROR, xmlFailed); var myXML:XML; //--when the xml is loaded, do this function xmlLoaded(e:Event):void { myXML = XML(myLoader.data); trace("XML = "+myXML); } //--if the xml fails to load, do this function xmlFailed(event:IOErrorEvent):void { errorMsg.text = "The XML file cannot be found" }

  • Help with Btree homework

    - by Phenom
    I need to do a preorder traversal of a Btree, and among other things, print the following information for each page (which is the same thing as a node): The B-Tree page number The value of each B-Tree page pointer (e.g., address, byte offset, RRN). My questions are: 1. How do you figure out the byte offset? What is it offset from? 2. Isn't the RRN the same as the page number? Note: A Btree is NOT A BINARY TREE. Btrees can have multiple keys in each node, and a node with n keys has n+1 child pointers.
