• Simple way to embed an MP3 audio file in a (static) HTML file, starting to play at a specifc time?

  - by Marcel

  Hi all, I want to produce a simple, static HTML file, that has one or more embedded MP3 files in it. The idea is to have a simple mean of listening to specific parts of an mp3 file. On a single click on a visual element, the sound should start to play; However, not from the beginning of the file, but from a specified starting point in that file (and play to the end of the file). This should work all locally from the client's local filesystem, the HTML file and the MP3 files do not reside on a webserver. So, how to play the MP3 audio from a specific starting point? The solution I am looking for should be as simple as possible, while working on most browsers, including IE, Firefox and Safari. Note: I know the <embed> tag as described here, but this seems not to work with my target browsers. Also I have read about jPlayer and other Java-Script-based players, but since I have never coded some JavaScript, I would prefer a HTML-only solution, if possible.

• Google Analytics Event Tracking and Variable visibility.

  - by Jeow

  Hi guys, I have added to my html page the standard latest snippet to get google analytics to work: ... ... var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-15080849-1']); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = 'http://www.google-analytics.com/ga.js'; (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(ga); })(); Now looking at the official 'event tracking guide' google says: add a snippet such as: pageTracker._trackEvent('Videos', 'Play', 'Gone With the Wind'); my question is: where is pageTracker coming from ? is it a global object in ga.js ? but if it is, why google did not tell me that they run a risk on breaking some script... I must be missing something any help really appreciated.

• Error returning Ajax in IE7

  - by GuiPereira

  Hi everybody! It's my first question here. First of all, sorry for my 'not perfect' english... I'm developing an ASP.NET MVC application with AJAX. I have the following code in the View: <% using(Html.BeginForm(null, "Home", FormMethod.Post, new{id="formcpf"})){ %> <p> <input name="tipo" type="radio" value="GeraCPF" /> CPF <input type="radio" name="tipo" value="GeraCNPJ" /> CNPJ </p> <p> <input type="submit" id="sbmt" value="Gerar" /> <br /><br /> <span id="lblCPF" class="respostaBG"></span> </p> <%} % and the following Javascript to call an Ajax request: $(document).ready(function() { $("form#formcpf").submit(function(event) { $(this).attr("action", $("input[@name='tipo']:checked").val()); event.preventDefault(); hijack(this, update_sessions, "html"); }); }); function hijack(form, callback, format) { $.ajax({ url: form.action, type: form.method, dataType: format, data: $(form).serialize(), success: callback }); } function update_sessions(result) { $("#lblCPF").html(result); } in Firefox and Chrome works fine, but in IE7 sometimes returns the value into the label, sometimes not. I have to keep submiting to get the return. Anyone could help?

• How to use reflection to call a method and pass parameters whose types are unknown at compile time?

  - by MandoMando

  I'd like to call methods of a class dynamically with parameter values that are "parsed" from a string input. For example: I'd like to call the following program with these commands: c:myprog.exe MethodA System.Int32 777 c:myprog.exe MethodA System.float 23.17 c:myprog.exe MethodB System.Int32& 777 c:myprog.exe MethodC System.Int32 777 System.String ThisCanBeDone static void Main(string[] args) { ClassA aa = new ClassA(); System.Type[] types = new Type[args.Length / 2]; object[] ParamArray = new object[types.Length]; for (int i=0; i < types.Length; i++) { types[i] = System.Type.GetType(args[i*2 + 1]); // LINE_X: this will obviously cause runtime error invalid type/casting ParamArray[i] = args[i*2 + 2]; MethodInfo callInfo = aa.GetType().GetMethod(args[0],types); callInfo.Invoke(aa, ParamArray); } // In a non-changeable classlib: public class ClassA { public void MethodA(int i) { Console.Write(i.ToString()); } public void MethodA(float f) { Console.Write(f.ToString()); } public void MethodB(ref int i) { Console.Write(i.ToString()); i++; } public void MethodC(int i, string s) { Console.Write(s + i.ToString()); } public void MethodA(object o) { Console.Write("Argg! Type Trapped!"); } } "LINE_X" in the above code is the sticky part. For one, I have no idea how to assign value to a int or a ref int parameter even after I create it using Activator.CreatInstance or something else. The typeConverter does come to mind, but then that requires an explicit compile type casting as well. Am I looking at CLR with JavaScript glasses or there is way to do this?

• Password Confirmation Overlay

  - by Alasdair

  Hello, I'm creating a J2EE web application that uses jQuery and Ajax to help with some of the presentation for a user-friendly interface. I've done a lot of work ensuring security around persistant login cookies, and I've decided to request the password from any user that logged in using a persistant login cookie before being allowed to make any changes that could be malicious. This request would only happen once to confirm the user is who they say they are and will last throughout the session. At present, any requests that meet this criteria has their request information stored in session and then the user is forwarded to a page to confirm their password. Once confirmed, the user's original request is then performed and the requestion information removed from session. What I would like to do is avoid all this redirection and minimize what's held in session (even if it's just for a small time), thus improving usability and convenience for the user. I believe that a jQuery overlay could allow me to prompt the user for their password (if required) and then continue to submit the request if successful. I would of originally used ThickBox, but since that's now deprecated I don't see the benefit in implementing it in an application at this development stage. However, I have tried to create an overlay using jQuery but I've scrapped every attempt as I can't seem to make it all come together. My main problem is preventing the submission when the user incorrectly types a password or cancels the overlay. Desired Flow Persistant Login Sensitive Page Submit Password Confirmation Overlay [Continue Submit | (Cancel | Incorrect] I have already created JavaScript code to encrypt the password to be sent in a parameter, but all I need now is a method of controlling the overlay and how best to use Ajax for this purpose. Please ignore the fact that this is a J2EE web application when answering as it is irrelevant really. Thanks in advance, Alasdair

• Display gridview in new window

  - by Ricardo Deano

  Hello all. Just a bit of advice needed really in terms of how I should handle my current scenario: I have a web page that searches for products/category information the results of which are at present displayed in a gridview on the same page. However, said gridview is a bit of a beast and as such, I would like to have a page that the user searches for, a button is pressed and the subsequent gridview is displayed in a new window. Ultimately, I would like the user to be able to make multiple searches so that new windows can have multiple gridviews containing different data sets. My current thinking is to create session variables that can be pulled through onto 'the gridview page'. Having said that, I'm not sure that would work if multiple searches are created? I am also thinking I might be able to create said 'gridview window' using javascript but my concern here is the potential loss of functionality of the gridview i.e. paging, sorting, editing, etc. Does anyone have any thoughts or theories on this? What would be "best practise"? Any thoughts greatly appreciated and taken on board. PS: This is being developed in .net, using c# and LINQ. PPS: I'm a noob so be gentle!!

• GET and XMLHttpRequest

  - by Neethusha

  i have an XMLHttpRequest.The request passes a parameter to my php server code in /var/www. But i cannot seem to be able to extract the parameter back at the server side. below i have pasted both the codes: javascript: function getUsers(u) { alert(u);//here u is 'http://start.ubuntu.com/9.10' xmlhttp=new XMLHttpRequest(); var url="http://localhost/servercode.php"+"?q="+u; xmlhttp.onreadystatechange= useHttpResponse; xmlhttp.open("GET",url,true); xmlhttp.send(null); } function useHttpResponse() { if (xmlhttp.readyState==4 ) { var response = eval('('+xmlhttp.responseText+')'); for(i=0;i<response.Users.length;i++) alert(response.Users[i].UserId); } } servercode.php: <?php $q=$_GET["q"]; //$q="http://start.ubuntu.com/9.10"; $con=mysql_connect("localhost","root","blaze"); if(!$con) {die('could not connect to database'.mysql.error()); } mysql_select_db("BLAZE",$con) or die("No such Db"); $result=mysql_query("SELECT * FROM USERURL WHERE URL='$q'"); if($result == null) echo 'nobody online'; else { header('Content-type: text/html'); echo "{\"Users\":["; while($row=mysql_fetch_array($result)) { echo '{"UserId":"'.$row[UsrID].'"},'; } echo "]}"; } mysql_close($con); ?> this is not giving the required result...although the commented statement , where the variable is assigned explicitly the value of the argument works...it alerts me the required output...but somehow the GET method's parameter is not reaching my php or thats how i think it is....pls help....

• IE8 CSS Table Effect

  - by Ian

  I've been trying to make this cross browser (specifically IE), but I do not want to use tables. I will not be able to specify the container width with CSS because its contents (the image) will dynamically change with Javascript, so I need the container to 'auto-size' horizontally. The desired effect would be a centered image with two sets of text (one of the left and one of the left) directly underneath the image, aligned to it's inner edges. Example (Doesn't work on IE): http://pastehtml.com/view/19pbyw9.html <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <style type="text/css"> #container { display:table; } </style> </head> <body> <center> <div id="container"> <img src="http://www.google.com/intl/en_ALL/images/srpr/logo1w.png" alt="" /><br /> <span style="float: left;">test</span> <span style="float: right; text-align: right;">test2</span> </div> </center> </body> </html>

• How can I print a web page on a server?

  - by Gavin Schultz

  Suppose I develop a web page using the cool Google visualization API, and it does everything the user wants. They can the parameters, look at the graphs, and print the page to get a reasonable-looking report. All good. Now suppose I want to do the same thing server-side. For example, say we need a set of report generated at a specific time of day, printed to a PDF and emailed to a manager. It's not a user-initiated action, so we don't have a user's browser or their printer. We have a URL that would render the report if we had a browser, and that's it. Is there a good way to do this server-side? Is this just foolish? Has anyone done anything like that before? Do any of the major browsers have APIs that might provide such functionality? Keep in mind too that it's not just static HTML; probably javascript will be running first to shift the DOM around. I know we could implement a whole different reporting engine on the server side to do this, but that will (a) generate reports that look a bit different, and (b) require me to build/maintain two sets of functionality. Instead, I'd be happy if I could just render the page / pages I want in an invisible server-side browser and print it to a PDF (let's mostly ignore that step - I know any number of PDF printer drivers that could do this). I don't really want to do it ugly either - i.e. by starting a browser process and then sending keystrokes directly to the window either - that's just bound to fall apart with a slight nudge. The only related question I found had an answer like that. Any advice appreciated!

• jQuery XML loading and then innerfade effect

  - by Ryan Max

  Hello, I think I can explain myself without code, so for brevity's sake here we go: I am using jquery to pull data from an xml and put it into a ul on the page with each xml entry as a li. This is working great! However, what I am trying to do afterwards is use the innerfade plugin to make a simple animation between each of the li's. It's not working though, as it is still just loading the static list with each item visible (whereas if innerfade was working it would only display the first....then fade into the second, etc) It's not an innerfade problem however, because if I add the list in manually to the page (not injecting it with jquery) then the innerfade works fine. I'm relatively new to DOM scripting, so I think I am missing something here. I'm not quite sure how jQuery sequences everything, and I'm having trouble phrasing my question in a search engine friendly manner so here I am. Is it possible to have jquery pull the data from xml, then inject it into the page, then have innerfade work it's magic? Or am I thinking about this the wrong way? xml code: $.ajax({ type: "GET", url: "xml/playlist.xml", dataType: "xml", success: function(xml) { $(xml).find('song').each(function(){ var name = $(this).attr('title'); var date = $(this).attr('artist'); var message = $(this).attr('path'); $('<li></li>').html('<span id="an_name">'+name+'</span><span id="an_date">'+date+'</span><span id="an_message">'+message+'</span>').appendTo('#anniversary'); }); } }); innerfade code: <script type="text/javascript"> jQuery.noConflict(); jQuery(document).ready( function(){ jQuery('#anniversary').innerfade({ speed: 1000, timeout: 5000, type: 'sequence', }); });

• Python alignment of assignments (style)

  - by ikaros45

  I really like following style standards, as those specified in PEP 8. I have a linter that checks it automatically, and definitely my code is much better because of that. There is just one point in PEP 8, the E251 & E221 don't feel very good. Coming from a JavaScript background, I used to align the variable assignments as following: var var1 = 1234; var2 = 54; longer_name = 'hi'; var lol = { 'that' : 65, 'those' : 87, 'other_thing' : true }; And in my humble opinion, this improves readability dramatically. Problem is, this is dis-recommended by PEP 8. With dictionaries, is not that bad because spaces are allowed after the colon: dictionary = { 'something': 98, 'some_other_thing': False } I can "live" with variable assignments without alignment, but what I don't like at all is not to be able to pass named arguments in a function call, like this: some_func(length= 40, weight= 900, lol= 'troll', useless_var= True, intelligence=None) So, what I end up doing is using a dictionary, as following: specs = { 'length': 40, 'weight': 900, 'lol': 'troll', 'useless_var': True, 'intelligence': None } some_func(**specs) or just simply some_func(**{'length': 40, 'weight': 900, 'lol': 'troll', 'useless_var': True, 'intelligence': None}) But I have the feeling this work around is just worse than ignoring the PEP 8 E251 / E221. What is the best practice?

• jQuery Accordion + OL + IE6 bug

  - by DA

  Sample page: http://jsbin.com/ohuze/2 This is a simple jQuery UI Accordion. Each accordion panel has an UL (an OL works the same) with this markup: <ol> <li><a href="">Lorep ipsum dolor lorem ipsum dolor lorem ipsum dolor</a>?</li> <li><a href="">Lorep ipsum dolor lorem ipsum dolor lorem ipsum dolor</a>?</li> </ol> In IE6, you'll see that the <a> tag appears to be getting rendered as a block element, so the question mark ends up being pushed outside and not at the end of the line of text. In addition, the bullet and/or list item number is now bottom-aligned with the text rather than top-aligned. I've narrowed it down to the javascript that executes to make the accordion. It's not an issue with jQuery's CSS as disabling that, alone, doesn't resolve the issue. Anyone know what might be going on in IE6 to cause this rendering issue? UPDATE: Apparently, this is also an IE7 issue.

• Preventing a button from responding to 'Enter' in ASP.net

  - by kd7iwp

  I have a master template that all the pages on my site use. In the template there is an empty panel. In the code-behind for the page an imagebutton is created in the panel dynamically in my Page_Load section (makes a call to the DB to determine which button should appear via my controller). On some pages that use this template and have forms on them, pressing the Enter key fires the click event on this imagebutton rather than the submit button in the form. Is there a simple way to prevent the imagebutton click event from firing unless it's clicked by the mouse? I'm thinking a javascript method is a hack, especially since the button doesn't even exist in the master template until the button is dynamically created on Page_Load (this is ugly since I can't simply do <% =btnName.ClientId %> to refer to the button's name in my aspx page). I tried setting a super-high tabindex for the image button and that did nothing. Also set the button to be the DefaultButton in its panel on the master template but that did not work either.

• ASP.NET Repeater, Dynamically starting new table row

  - by dherrin79

  I have the following repeater: <table> <asp:Repeater runat="server" ID="rptBrandRepeater"> <ItemTemplate> <tr> <td> <asp:HyperLink runat="server" ID="lnkCompanyLink"> <asp:Image runat="server" ID="imgCompanyLogo" /> </asp:HyperLink> </td> </tr> </ItemTemplate> </asp:Repeater> </table> I want to start a new row every four table cells. I don't want to used jQuery or Javascript to accomplish this. The outputted html is supposed to look like this page: http://rmtequipment.com/golfandturf.aspx I have made an interface that will allow them to add these logos on their own. So this page will be dynamically built. What is the best way to accomplish this goal? If a listview or gridview is a better approach I am open to that as well. Thanks in advance.

• Which language should I use to program a GUI application?

  - by Roman

  I would like to write a GUI application for management of information (text documents). In more details, it should be similar to the TiddlyWiki. I would like to have there some good visual effects (like nice representation for three structures, which you can rotate, some sound). I also would like to include some communication via Internet (for sharing and collaboration). In should include some features of such applications as a web browser, word processor, Skype. Which programming language should I use? I like the idea of usage of JavaScripts (like TddlyWiki). The good thing about that, is that user should not install anything. They open a file in a browser and it works! The bad thing is that JavaScript cannot communicate via internet with other applications. I think the choice of the programming language, in my case, id conditioned by 2 things: What can be done with this programming language (which restrictions are there). How easy to program. I would like to have "block" which can do a lot of things (rather than to program then and, in this way, to "rediscover a bicycle") ADDED: I would like to make it platform independent.

• sem-dynamic cdn

  - by dwi kristianto

  i'm developing couple of websites using php (directory script, etc.) and wordpress as cms. i need to improve its performance, by using cdn for static files (css, js, images). the problem is, css and javascript files are generated on the fly. i did that due to yahoo and some expert advice to combine the files into one file. also changing basic color of css files. for the time being, i use couple of small vps but still its not fast enough. i already contact maxcdn and the support guy said that they dont have such kind of services. what i need is: a cdn that will serve the request from user/visitor and there's no file in local disk, the cdn will redirect/fetch it from another domain/server. in vps, it could be done easily using combination of .htaccess and php, but NOT in the cdn. most of cdn only support purely static files. is there any such cdn that will server semi-dynamic files?

• HTML5 Shiv not parsing quick enough

  - by Mikey Hogarth

  One of our web designers is working on a site at the moment and is using HTML5 elements, which she styles up in older browsers using the well documented Html5Shiv; http://css-tricks.com/html5-innershiv/ She reported some pretty weird behavior today and it looks like this is the cause. Initially it was very confusing, and went something along the lines of; "The page looks fine, I refresh it looks fine, refresh several times and occasionally it will not apply my styles to the HTML5 elements" Current best theory is that the shiv is not kicking in quick enough, and the page loads before the new elements have been registered. I was wondering if anyone could suggest a surefire way of including the shiv and making sure it's loaded and been parsed BEFORE the rest of the elements, so they will definitely get styled. EDIT (more info) Shiv is being included in the head, directly below the title/meta tags; <!--[if IE]> <script type="text/javascript" src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script> <![endif]--> The bit that is being styled is in the footer and is cross-site. Many of the pages will change in size as they're being powered by a CMS that our marketing team will use so I am unable to give an exact page size. All I would say is that if page size is an issue and there is no workaround, can someone let me know as this will mean we basically can't use HTML5 on this project (or at the very least we'll need to add superflous markup such as divs to ensure that the layout doesn't go crazy) EDIT 2 There is no chance of me posting the code unfortunately - it's only re-creatable under really obscure circumstances and the project is marked "top secret" at the moment :( If nobody knows then I'm guessing it's either a case of "everyone knows it happens but kinda ignores it" or just that it's something else other than the shiv.

• Colorbox does not refresh its contents when I change URL

  - by Josef Sábl

  I am trying to make use of Colorbox on my webpage. One specific feature does not work as expected, though. In their example (Outside Webpage - Iframe specifically) Google appears in the Colorbox when clicked. When you change href on that link (Using Firebug or JavaScript, e.g.) to, let's say, Yahoo, it works as expected and Yahoo is displayed after click. But not in my case. Once I click the link, I have no way to change the URL. Href, as displayed in browser, changes (to Yahoo), but click always opens the first page (Google). What might be the problem? I almost copy-pasted their example: <script src="/lib/jquery.js"></script> <script src="/lib/jquery.colorbox.js"></script> <p><a class='example7' href="http://yahoo.com">Outside Webpage (Iframe)</a></p> <script> $(document).ready(function(){ $(".example7").colorbox({width:"80%", height:"80%", iframe:true}); }); </script> My jquery version is 1.4.1 but I also tried same version as their example uses (1.3.2)

Here is how i implemented it on Javascript function validateClubCardNumber() { var varClubCardNumber = $('#clubCardNumber').val(); $('#phoneNumber').val(""); var returnVal = true; if ((null == varClubCardNumber || '' == trim(varClubCardNumber)){ return false; } if( varClubCardNumber.length < 10 ){ return false; }else if( varClubCardNumber.length == 10 ) { //The Phone Number field should contains numbers only var pattern = /^[0-9 -]*$/ ; var flag = pattern.test(trim(varClubCardNumber)); if(flag == false){ return false; }else{ $('#phoneNumber').val(varClubCardNumber); returnVal = true; } } } return returnVal; } HTML <div > <label for="clubCardNumber" >Card or Phone Number:</label> <input id="clubCardNumber" name="clubCardNumber" type="text" placeholder="Card or Phone Number" value="" maxlength="20"/> </div> <input type="hidden" id="phoneNumber" name="phoneNumber" value=""/>

• How to set focus to a web control in ASP.NET

  - by Dan7el

  Question: What is the best way to set focus to a web control in ASP .NET. I can do it, but it's ugly. I have a web control wrapped in a web control hosted on a web page. So, if you do a view | source on the page the id is something like WrapperControl_Control_TextBox. I've tried the "tried and true" Javascript methods of grabbing the element and setting it's focus: document.getElementByID( "WrapperControl_Control_TextBox" ).focus(); and it didn't work. I'm not sure why. I know I could possibly do: document.getElementById( "<%= TextBox.ClientID %" ).focus(); too, I think. This won't work because of another totally separate error based on the fact you can't dynamically add controls to a header if there is a "<% %" in the page. GAH. In the "bottom-most" control, I've tried setting the focus (TextBox.Focus() in Page_Load) and that doesn't work either. Anyway, the way that works is by simply taking the ControlsCollection of the Page, grabbing the control I need from that, getting it's collection, grabbing the next lower control and so forth. I only have to do this seven times. So I have eight foreach loops. Basically, my code is like this: /////////////////////////////// // On the page /////////////////////////////// ControlCollection controls = Controls; foreach( Control control in controls) { if ( string.Equals( control.ID, "FormID", StringComparison.InvariantCultureIgnore ) ) { ControlCollection nextControls = control.Controls; foreach( Control nextControl in nextControls ) { if ( string.Equals( nextControl.ID, "DivICareAboutInTheForm", StringComparison.InvariantCultureIgnor ) ) { ControlCollection nextNextControls = nextControl.Controls; //: //: //Yes, it's that bad and so forth. //: //: } } } }

• Disposing underlying object from finalizer in an immutable object

  - by Juan Luis Soldi

  I'm trying to wrap around Awesomium and make it look to the rest of my code as close as possible to NET's WebBrowser since this is for an existing application that already uses the WebBrowser. In this library, there is a class called JSObject which represents a javascript object. You can get one of this, for instance, by calling the ExecuteJavascriptWithResult method of the WebView class. If you'd call it like myWebView.ExecuteJavascriptWithResult("document", string.Empty).ToObject(), then you'd get a JSObject that represents the document. I'm writing an immutable class (it's only field is a readonly JSObject object) called JSObjectWrap that wraps around JSObject which I want to use as base class for other classes that would emulate .NET classes such as HtmlElement and HtmlDocument. Now, these classes don't implement Dispose, but JSObject does. What I first thought was to call the underlying JSObject's Dispose method in my JSObjectWrap's finalizer (instead of having JSObjectWrap implement Dispose) so that the rest of my code can stay the way it is (instead of having to add using's everywhere and make sure every JSObjectWrap is being properly disposed). But I just realized if more than two JSObjectWrap's have the same underlying JSObject and one of them gets finalized this will mess up the other JSObjectWrap. So now I'm thinking maybe I should keep a static Dictionary of JSObjects and keep count of how many of each of them are being referenced by a JSObjectWrap but this sounds messy and I think could cause major performance issues. Since this sounds to me like a common pattern I wonder if anyone else has a better idea.
