• Is is possible to parse a web page from the client side for a large number of words and if so, how?

  - by Technoh

  I have a list of keywords, about 25,000 of them. I would like people who add a certain < script tag on their web page to have these keywords transformed into links. What would be the best way to go and achieve this? I have tried the simple javascript approach (an array with lots of elements and regexping/replacing each) and it obviously slows down the browser. I could always process the content server-side if there was a way, from the client, to send the page's content to a cross-domain server script (I'm partial to PHP but it could be anything) but I don't know of any way to do this. Any other working solution is also welcome.

• n00b: receive input over TCP/IP and use it to update HTML

  - by mawg

  This has got to be a FAQ, so can someone please just direct me to a "network programming for dummies" URL? The server wants to push information to a client or broadcast to all, when an event happens - as opposed to the clients constantly polling the server "just in case". The client then updates a browser page display. How do I do that? (toldya it was a n00b question) Should I have a thread which receives info on a socket and then writes it to a database which the browser display (PHP) can process with an HTML refresh tag, or what? Sorry to sound so dumb.

• Whats the Best Practice for a Search SQL Query?

  - by Marc V

  I have a SQL 2008 Express database, which have following tables: CREATE TABLE Videos (VideoID bigint not null, Title varchar(100) NULL, Description varchar(MAX) NULL, isActive bit NULL ) CREATE TABLE Tags (TagID bigint not null, Tag varchar(100) NULL ) CREATE TABLE VideoTags (VideoID bigint not null, TagID bigint not null ) Now I need SQL query to search for word (i.e. Beyonce Halo Music Video) against these tables. Which videos have: For Title exact phrase will get 0.5 points For Description exact phrase will get 0.4 points For tags exact phrase will get 0.3 points For title all words will get 0.2 points For description all words will get 0.2 points For title one or more words will get 0.1 points For description one or more words will get 0.1 points And I will show these videos on basis of points. What will be the SQL Query for this? A LINQ query will be more better. If you know a better way to achieve this, please help.

• Passing value from :locals to link_remote_to

  - by Teef L

  In my edit.haml file, I have =render :partial => 'old_question_tags', :locals => {:current_question => @question.id}. I'd like to pass the value in :current_question to a link_to_remote call in _old_question_tags.haml: #{link_to_remote image_tag('red-x.png', {:alt => "Remove #{t.name} tag"}), :url => {:action => 'remove_old_tag_from_question', :tag_remove => t.id, :current_question => current_question}} But I get this error on the link_to_remote line: ActionView::TemplateError (undefined local variable or method `current_question' for #<ActionView::Base:0xdb2fec8>) In _old_question_tags.haml, if I just print current_question (using =current_question), it prints the number without any problems. How do I properly pass that value to the partial so that I can pass it to the link_to_remote call?

• Joomla Session Variable as Plugin Parameter

  - by dosboy

  I have a Joomla plugin which takes varying parameters. I need to retrieve one of these parameters from the current session. I've tried using Jumi and a little PHP snipped to retrieve the value and output it in the plugin's parameter list, but the Joomla plugin parser only handles the outter-most set of curly braces. ex. {fabrik view=table id=62 resetfilters=1 fab_tours_ro___tour_id=[tour_id]} [tour_id] I need to retrieve from the current session. I've tried {fabrik view=table id=62 resetfilters=1 fab_tours_ro___tour_id={jumi [scripts/get_tour_id.php]}} In that case the {jumi} tag never gets parsed. I could hack the {fabrik} plugin, but I'd prefer to do this without making any core or component changes, especially since I update Fabrik quite regularly via svn.

• Finding the "name" of your Android application.

  - by fiXedd

  Is there any way to (programatically) find out what your app's name is? I'm specifically talking about the android:label property from the application tag in the manifest file: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.test" android:versionCode="1" android:versionName="1.0"> <application android:label="THIS THING HERE!" android:icon="@drawable/icon"> <!-- ... --> </application> </manifest>

• My image does not load on a jQuery fade in effect even though the div loads.

  - by Konstantin

  jQuery(document).ready(function() { if (useMSIE){ pngfixALL(); }; jQuery(div).show(data_fadeInEffect, 500);return false; // jQuery(div).animate({opacity:1}, 500, 'linear'); }); This is what I have for a fade in effect. When using animate(), the image in the div tag fades in fine. However, when I use show(), the div loads because I can click in that area, but the image itself doesn't load. Why is this happening? I have another area of the code where I click on an 'x' in the image and it fades out using hide(). This works fine.

• Using indentation to make CSS more readable? (making parents and children more identifiable in CSS)

  - by janoChen

  I've been always guiding myself with the following CSS structure: #nav { } #nav li { } #nac li a { } This structure tells me clearly who is the parent and the child. But in a recent article (I think it was CSS Trick) someone said that CSS is read from right to left. So the more tags I had the slower it will be (and sometimes I think its unnecessary to write every single tag involve in the selector). So it may be something like this: #nav { } #special-link { } where #special-link is #nav's child. I know this is not a big problem in a simple stylesheet but in a big one I always would get confused about who is who's parent and child. Another solution would be: #nav { } #special-link { } Indentation How do you solve with this CSS dilemma?

• iphone web app: open directions in external maps application

  - by munchybunch

  I've seen the answers for opening the Maps app in a native iPhone app, but is there any way to do this in a web app? I've tried changing window.location to http://maps.google.com/maps?q=cupertino for example, to no avail. I've tried using a simple anchor tag linked to http://maps.google.com/maps?q=cupertino, also to no avail. Has anyone gotten this to work before? I'm working on a map-heavy application, and I'd like to provide users with directions at the end. I figured it would be easiest to simply open it up in the Map application. Note: I'm currently testing with just the simulator, could that lead to problems? My iPhone is down for the count at the moment.

• Different i18n in spring according to url

  - by Fanooos

  I have a spring web application that is required to work as following the application will be accessed from two different URLs www.domain1.com and www.domain2.com and it is required that the two URLs looks like two different applications with different CSS and I18n. for the css part is done but I am stuck with the i18n part How to make spring load different i18n properties file according to the domain name? The solution that I thought in is to implement a filter that check the request URL and according to the URL it clears the message source bean and load the required i18n file but it does not looks good for the performance by the way I am using ReloadableResourceBundleMessageSource message source Another solution is to implement two different message sources. The problem with this solution is that from the source code I can manage the bean that I use but how can I tell the fmt:message tag which data source to use ? Thanks in advance and best regards

• jquery disable rule validation on a single field

  - by shake

  I am using mvc to create forms that are generated at runtime. For validation, I am trying my hand at the jquery validation library which is very convenient to use. I have the validation expression of each field in the cdata attribute of the tag <input type="text" name="xyz" id="xyz" class="defaultTextBox" cdata="{validate:{required:true, decimal:true, messages: {required:'Please enter an decimal value', decimal:'Please enter a valid decimal'}}}"> This works beautifully. Now one more requirement I have is that some fields are being shown and hidden according to the logic on the page and I need to disable the validation on the hidden fields such that they do not interfere with the form submission. Just toggling the required:true to false and back to true should be enough. Only i do not know how. Anyone has any experience with that?

• Upload/Download files with ASP.Net using Visual Studio Web Server

  - by jlnorsworthy

  I need to upload image files and store them on the webserver, then be able to display them in html. I'm currently using AppDomain.CurrentDomain.BaseDirectory to get a path to read and write files. Firefox won't display the image as I just get an img tag with "src='C:...' Is it possible to read/write files like this with Visual Studio web server? I know it'll be possible with IIS, but I don't want to do that if I don't have to (pretty new to web development) I'm implementing this with ASP.Net MVC 2, but I don't think that is relevant.

• How can I merge CSS definitions in files into inline style attributes, using Perl?

  - by mintywalker

  Many email clients don't like linked CSS stylesheets, or even the embedded <style> tag, but rather want the CSS to appear inline as style attributes on all your markup. BAD: <link rel=stylesheet type="text/css" href="/style.css"> BAD: <style type="text/css">...</style> WORKS: <h1 style="margin: 0">...</h1> However this inline style attribute approach is a right pain to manage. I've found tools for Ruby and PHP that will take a CSS file and some separate markup as input and return you the merged result - a single file of markup with all the CSS converted to style attributes. I'm looking for a Perl solution to this problem, but I've not found one on CPAN or by searching Google. Any pointers? Alternatively, are there CPAN modules one could combine to achieve the same result? Ruby http://code.dunae.ca/premailer.web/ PHP http://www.pelagodesign.com/sidecar/emogrifier/ Perl ?

• Can an XML prolog contain custom information?

  - by DaveJohnston

  Is it legal to add additional custom information somewhere in an XML prolog? For example, in my case, I would like to add an indicator of which serialiser version was used to create the XML, so that clients receiving the XML could automatically select the correct corresponding de-serialiser. I could add the information as an attribute of the root tag, but I thought it would be cleaner to add the information in the prolog, like the standard XML version: <?xml version="1.0"?> something like: <?serialiser version="1.0"?> or is the prolog reserved purely for those things specified by W3C?

• Flex custom toggleswitch not working in actionscript

  - by Gavin Jones

  I have a custom Flex Toggleswitch component that changes the text values of the switch. package skins { import spark.skins.mobile.ToggleSwitchSkin; public class MyToggleSwitchSkin extends ToggleSwitchSkin { public function MyToggleSwitchSkin() { super(); selectedLabel="Serviceable"; unselectedLabel="Fault"; } } } If I add the control using the MXML tag, it works fine. However, when I add the component using action script, it does not. import skins.MyToggleSwitchSkin; public function addToggle():void { var myCustomToggle:MyToggleSwitchSkin = new MyToggleSwitchSkin(); hgroup.addElement(myCustomToggle); } The control dsiplays but will not activate. Any ideas what I have missed?

  So I have this shopping list coded in php and js: http://www.whatcouldicook.com/recipes/planner So people can add, delete or sort the list and thats fine, I dont want multiple lists and instead just have a list item containing a heading tag to represent a new list.

• Printing UTF-16 strings in JSP is outputted as HTML encoding (&#xxxx)

  - by Ori Osherov

  Hello, When I try to print a UTF-16 string in JSP, specifically Hebrew, it ends up showing up as HTML encoding (&#xxxx). This problem occurs because I print an array of variables into the web page and then parse them. The variables are all UTF-16 strings, but once the servlet prints the variables, it becomes translated to HTML encoding. Is there any way to get rid of the encoding? Thanks in advance Edit for a bit more background: The JSP that I'm printing is not the entirety of the page. It's used in a manner I don't quite understand by a server app which prints the JSPs output into its built in page. As a result, I can't, for instance, use a tag because the will have already been placed somewhere else. This isn't a frame or anything like that. It's just redirected output.

• How to use GWT on mobile devices?

  - by Chris

  hi I have a fairly large web application developed with GWT (and EJB). However on mobile devices (like windows mobile, black berry and such) the GWT start page remains simply white. I'm using GWT 1.6 and also tried 1.7 but nothing helps. It seems that the java script isn't executing and also isn't the noscript tag. Do you know how to make it working without rewriting the whole application in e.g. PHP?? I think it may be a general prob with GWT apps and not with my specific app. thx

• parsing xml attribute value

• Listen to HTML/CSS events of web page

  - by David Metcalfe

  I'm looking for a way to listen for an event in the HTML/CSS of a webpage. Basically, a website I use at work lists queues and appointments, which flag as yellow/red based on the amount of time late on taking said appointment. Other than this visual aide, there is no alert of any kind, which is a failing point if one is juggling multiple windows and doesn't notice. What I would like to do is put together a simple way to watch for the tag ID or perhaps the flag hex color, and then alert me in a way of my choosing. The work environment is on OS X, so I presume I'm looking at an Objective-C centric solution unless Applescript is capable of doing this. Any help would be greatly appreciated.

  Hi, there is a script in my html tag <script type="text/javascript"> function setTaxDisplay(display) { window.location.href += (window.location.href.indexOf('?') > -1 ? '&' : '?') + 'taxInclude=' + display; } </script> When passed to validation It returns that the ampersand there isn't valid, but it's absolutely vital to the function of the page, is there a way I can make the validator ignore this? I don't need to validate the page, I'm no JS expert at all I'm not sure if I can replace it with &amp;. Thanks.

• How to edit default.aspx on SharePoint site without SharePoint Designer

  - by Magnus Johansson

  On several occations, I have faced the situation that the default.aspx page on a Site doesn't work. More specifically, a reference to a WebPart and/or Control is throwing a error because the assembly is not found. Fine, you just fire up the dreaded SharePoint Designer and remove the dependency line. However, if I wanted to use this method when not having SharePoint Designer, how could this be done? EDIT: Removing the web part using the "?contents=1" web part management page didn't help in my case. The <%@Register tag was still there and had to be removed using SharePoint Designer.
