• Setting a Global Doctype

  - by Batfan

  Is it possible using PHP (I was thinking may the phpinfo file or a php.ini file) or an .htaccess file to set a doctype for an entire subdirectory? Basically, in a nutshell, I'm using a software that uses XSL templates to output data to a set of HTML files. Modifying the xsl:output tag to include the doctype breaks the template and therefore, does not work. Just adding the doctype in the XSL file, breaks it as well. I need the proper doctypes in place for my CSS to function properly, cross-browser. I realize that I could add the doctype to the HTML files after export but, I'm really striving to automate this process. Any thoughts?

• playing flv in website

  - by samoyed

  hello to all, my client wants to play a flash video in their website. just to make sure i understand correctly, i need to: 1. create an FLV file 2. use either some flv player or wrap the flv inside swf questions: 1. the player option - will visitor have to download /install it or is it install only once, in the website itself? any FREE player you can recommend the will ensure cross browser compatibility? swf option: will i need the flash application in order to do the wrapping? will i be able to later use something like flashobject library for the actual embedding? what are the main considerations for choosing between the two options , if indeed these are the options? any help would be highly appreciated. have a nice day and let's pray for a lot of goals today :-)

• Notepad++ Question

  - by Shane

  I would like a hotkey to Save All in Notepad++ then switch to the browser and refresh the page. I have to do this thousands of times a day and doing the Save All hotkey, then Alt-Tab to the right window, then F5 to refresh again and again, there must be a better solution? I am open to switching editors if there is another that can do this. I have tried using run commands but the problem is although it allows you to make something like [firefox.exe "current file"], if you come down to wanting to open it at a web address like localhost because it needs to run server side, then you have to manually specify the other part of the string, like [chrome.exe "custom var(web address) / filename"] and it always opens a new tab, then creates lots of clutter. Also, if you are editing an include file then it will try to open that instead of the page you want to see when you use the run command, a refresh would be the only realistic method I can think of using.

• Get client timezone (not GMT offset amount) in JS

  - by Rex M

  I need to determine the client timezone (e.g. CET, GMT, EST) in JS. Getting the offset is straightforward, but doesn't have all the info necessary to determine the TZ, at least not easily. I have a feeling it might be possible to use a combination of offset, whether DST is in use and in effect, etc. but I'm hoping someone else has done the work already, especially considering the weird exceptions when dealing with time. This question is similar but both the question and the answer are based on the (incorrect) assumption every browser's DateString format includes the name of the timezone - which it does not. That is an implementation detail. So, with that I am currently stuck.

• Prompts for windows authentication when viewing a page in Web site

  - by Sri Kumar

  Hello All, When i try to view a PARTICULAR page in my web site, it prompts for user name and password. Irrespective of providing proper user name/password and clicking OK or directly clicking Cancel button, the page is getting loaded properly. I am not sure why the authentication screen appears!!! It happens only for that particular page. Initially I thought it could be with file permission but copy pasted another page (which works fine) and renaming it doesn't solve the problem. Thoughts pl. EDIT I copied the source from the browser for that particular page and saved it as HTML. When i try to open the HTML file, it prompts for authentication.

• Is it safe to validate a URL with a regexp?

  - by Vilx-

  In my web app I've got a form field where the user can enter an URL. I'm already doing some preliminary client-side validation and I was wondering if I could use a regexp to validate if the entered string is a valid URL. So, two questions: Is it safe to do this with a regexp? A URL is a complex beast, and just like you shouldn't use a regexp for parsing HTML, I'm worried that it might be unsuitable for a URL as well. If it can be done, what would be a good regexp for the task? (I know that Google turns up countless regexps, but I'm worried about their quality). My goal is to prevent a situation where the URL appears in the web page and is unusable by the browser.

• Playback audio data with GWT

  - by Henrik

  I am creating a GWT client application which interacts with a server and I am getting all my response data from the server in JSON format. Amongst others there are wave data on the server's database which I would like to retrieve and then playback on the client. I am able to get the wave data as an array of bytes in the JSON format. My problem is, how do I playback the wave array data in a browser? Is it even possible or do I have to find another solution? I've searched the web and found some GWT packages which are able to playback sound, but they are all playing back directly from an url.

• Node.JS Server Cuts Off Frequently?

  - by aherrick

  I have a Node JS Server where I am using Socket.IO to stream content to the browser. It works great for about 45 minutes or so of streaming, then it will usually cut out. There are no "errors" reported in the terminal and the Node server acts like it is in, however the page I am serving clearly stops working. What are my options for trying to get to the bottom of this? Could this be a configuration issue with Node/Socket.IO? is there any basic error logging you would recommend I setup?

• Why are web developers so keen to use lists ?

  - by Bob

  I've been developing for a while and often develop sites using menu tabs. And I can't figure out why so many web developers like using lists < ul < li etc rather than just using plain old divs. I can make menus in divs which are simple and work perfectly in every browser. With lists, I'm usually trying to hack it one way or another to get it work properly. So my question is simple : why should I use lists to create my menus instead of divs ?

• how do i specify the element when loading content ajax jquery

  - by phukkie

  How can I specify an element where the content is to be retrieved from within the pageurl in the code below? $(function () { $("a[rel='sort']").click(function (e) { //e.preventDefault(); /* if uncomment the above line, html5 nonsupported browers won't change the url but will display the ajax content; if commented, html5 nonsupported browers will reload the page to the specified link. */ //get the link location that was clicked pageurl = $(this).attr('href'); //to get the ajax content and display in div with id 'content' $.ajax({ url: pageurl + '?rel=sort', success: function (data) { $('#content1').html(data); } }); //to change the browser URL to 'pageurl' if (pageurl != window.location) { window.history.pushState({ path: pageurl }, '', pageurl); } return false; }); });

• There was no endpoint listening at http://localhost:49481/Marketing.svc that could accept the message

  - by duckmike

  I have a Marketing service running locally through port 49481 and through IIS on port 65000. Either way when I try to debug into that service, I get an error message - {"There was no endpoint listening at http:/localhost:49481/Marketing.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details."} My inner exception is - {"The remote server returned an error: (404) Not Found."} I can open that service address, http:/localhost:49481/Marketing.svc, through a browser and I get a message that it's running ok. My config file is set up like - <endpoint address="http://localhost:49481/Marketing.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IMarketing" contract="SunriseMarketing.IMarketing" name="BasicHttpBinding_IMarketing" /> What am I missing?

• How to Create an Array from a Single Variable and Form Multiple Foreach Loops?

  - by matphoto

  I'm fairly proficient in HTML/CSS, but very new when it comes to the likes of PHP and Javascript. I've jumped headfirst into coding Wordpress shortcodes (basically php functions), and so far, through trial and error and seemingly endless browser refreshes, I've been able to figure everything out. I just hit a huge wall though, hence why I'm here. Basically, I'm trying to give an attribute a list of values like: attr="23, 95, 136, ect" The function then needs to take that attribute variable and create an array with it: $arr = array($attr); To me that seems as if it would work, but the array takes the whole list as one value instead. After doing that I want to create a foreach loop that parses each number from the list, possibly through yet another foreach loop if possible, and returns a section of code for each one, and I'm not quite sure how to pull that off either. Any feedback would be greatly appreciated.

• Key logger wont record key strokes without console

  - by Daniel Gopar

  I created a small basic key logger in C++. For some reason when I compile and run the program with the console displayed, it will record every key stroke I make in whatever program I am using such as a browser and store it in a text file. However when I make it so that it WON'T display a console window, it will not record anything and it's just a process in the background doing nothing. Here is the link to my code: http://pastebin.com/4wqQyLJ9 The function that is giving me trouble with hiding the console, is the Stealth() function. Any suggestions, tips or hints will be helpful. Thanks.

• Seeking not working in HTML5 audio tag

  - by lord_wilmore

  I have a lighttpd server running locally. If I load a static file on the server (through an html5 audio tag), it plays and seeks fine. However, seeking doesn't work when running a dev server (web.py/CherryPy) or if I return the bytes via a defined action url instead of as a static file. It won't load the duration either. According to the "HTTP byte range requests" section in this Opera Page it's something to do with support for byte range requests/partial content responses. The content is treated as streaming instead. What I don't understand is: If the browser has the whole file downloaded surely it can display the duration, and surely it can seek. What I need to do on the web server to enable byte range requests (for non-static urls). Any advice would be most gratefully received.

• Authenticating a user for a single app with multiple domains

  - by hofnarwillie

  I have one asp.net web application, but two different domains point to this web app. For instance: www.one.com and www.two.com both point to the same web app. I have an issue where I need certain pages to be on a specific domain (due to some security requirements from our online payment provider - a third party website). So let's say page1.aspx needs to be called on www.two.com The process is as follows: A user logs into www.one.com The authentication cookie is saved to the browser The user then navigates to page1.aspx and, if on the wrong domain, gets redirected to the correct domain. (this redirection happens on page1.aspx in the page_load event) Then asp.net redirects the user to the login screen, because the authentication cookie is not sent to www.two.com. How can I track the user and keep him/her logged in between the two domains?

• How to protect access to a url?

  - by ibiza

  I would need to create a php file that will do some work on my webserver and that will be called from a program on another server over the internet. Suppose the php file that will do the work is located at www.example.com/work.php What is the best way to protect unsollicited calls to the www.example.com/work.php? What I need is some mechanism so that when the intended program accesses the url (with some query string parameters), the work gets done, but if somebody type www.example.com/work.php in their browser, access will be denied and no work will be done. The way I've thought is to add some 'token' in the querystring that would be constructed by some algorithm from the calling program, a sample result could be to append to the url : ?key=randomKeyAtEachCall&token=SomeHexadecimalResultCalculatedFromTheKey and the key and token would be validated with a reverse algorithm on the php side. Is that safe, Are there any better idea?

• greasemonkey insert javascript

  - by Kaartz

  I have a bookmarklet, clicking the bookmarklet includes a PHP script (evaluated as a JavaScript file) to the page few table values and select values passed as GET parameters. The PHP script writes the page data to the MySQL database, and outputs a success message that is treated as JavaScript code and executed by the browser. Is there any possibility to do this using greasemonkey and call this function when a existing button is clicked on the web page. I wrote the above bookmarklet inspired by this tutorial. http://tutorialzine.com/2010/04/simple-bookmarking-app-php-javascript-mysql/ This is the bookmarklet code: (function () { var jsScript = document.createElement('script'); jsScript.setAttribute('type', 'text/javascript'); jsScript.setAttribute('src', '/bookmark.php?url=' + encodeURIComponent(location.href) + '&title=' + encodeURIComponent(document.title)); document.getElementsByTagName('head')[0].appendChild(jsScript); })(); Please help me.

• Fastest Way To Format a Plain Text Using Javascript

  - by Nathan Campos

  I have a huge plain text document, about 700kb which is very big for plain texts and I need to format it on cloud converting it to HTML, but the only things that I need to replace, format to HTML so it can be displayed by the browser, are bold and italic. For bold at the plain text they are like this: Not on bold... **bold text here** not bold here And italic like this: Not italic... *italic text* no italic Just like StackOverflow does for their formatting, but the problem is that I need to make it a lot faster, since the text is so big... One of my ideas was to add a page slide, so I the script just need to format some part of the text, not it all, then after the user changes the page the script would be called again, but the problem is how I can make the code for this all?

• HTTP Download very Big File

  - by Luca

  I'm working at a web application in Python/Twisted. I want the user to be able to download a very big file ( 100 Mb). I don't want to load all the file in memory (of the server), of course. server side I have this idea: ... request.setHeader('Content-Type', 'text/plain') fp = open(fileName, 'rb') try: r = None while r != '': r = fp.read(1024) request.write(r) finally: fp.close() request.finish() I expected this to work, but I have problems: I'm testing with FF... It seems the browser make me wait until the file is completed downloaded, and then I have the open/save dialog box. I expected the dialog box immediately, and then the progress bar in action... Maybe I have to add something in the Http header... Something like the size of the file?

• Pre-cache site as user visits

  - by strager

  I am making a static site which is 'forced' to be cached via Cache-control, etc. When a user visits my site, I want the browser to crawl my site, caching pages, so when the user navigates to a page, the load is almost instant. (I do not need a recursive crawl, as that will probably happen as the user navigates between pages. I just need to crawl the links on the current page, and of course not re-caching a page which has already been cached.) (Also, I am not changing pages using Ajax-like techniques. These are essentially normal flat HTML files with normal links.) How can I do this pre-caching using Javascript? (I am using jQuery.)

• Tool to measure Render time

  - by Noob

  Hi Folks, Is there a tool out there to measure the actual Render time of an element(s) on a page? I don't mean download time of the resources, but the actual time the browser took to render something. I know that this time would vary based on factors on the client machine, but would still be very handy in knowing what the rendering engine takes a while to load. I would imagine this should be a useful utility since web apps are becoming pretty client heavy now. Any thoughts?

• How can I catch a change event from an HTML text field when a user clicks on a link after editing?

  - by Eric the Red

  Our webapp has a form with fields and values that change depending on values entered. Each time there is a change event on one of the form elements, we use an expensive AJAX call to update other elements on the page. This works great for selects, radio buttons and checkboxes. The issue comes in when a user adds content to a text field, and then clicks a link without taking the focus from the text field. The browser moves to a new page, and the contents of the text field are never saved. Is there an easy way to code around this? The AJAX call is too expensive to call with each key press. Here's an example of my Prototype code at the moment: $$('.productOption input.text').invoke('observe', 'change', saveChangeEvent);

• Storing apostrophes, exclamation marks, etc. in mysql database

  - by rein

  I changed from latin1 to utf8. Although all sorts of text was displaying fine I noticed non-english characters were stored in the database as weird symbols. I spent a day trying to fix that and finally now non-english characters display as non-english characters in the database and display the same on the browser. However I noticed that I see apostrophes stored as &#39; and exclamation marks stored as &#33;. Is this normal, or should they be appearing as ' and ! in the database instead? If so, what would I need to do in order to fix that?
