Positioning decorated series of div tags on screen using offset, DOM JQUERY RELATED

- by Calibre2010

Hi, I am using JQuery to position a series of div tags which basically use a class inside of the tag which decorates the divs as bars. So the div is a green box based on its css specifications to the glass. I have a list of STARTING postions, a list of left coordiantes- for the starting points I wish to position my DIV say 556, 560, 600 these automatically are generated as left positions in a list I have a list of ENDING postions, a list of left coordiantes- for the ending points I wish to position my DIV say 570, 590, 610 these automatically are generated as left positions in a list now for each start and end position, the bar(green box) i want to be drawn with its appropriate width as follows. so say f is the offset or position of the start and ff the offset or position of the end : Below draws the green box based on only one start and end position LEFT. if (f.left != 0) { $("#test").html($("<div>d</div>")).css({ position: 'absolute', left: (f.left) + "px", top: (f.top + 35) + "px", width: (ff.left - f.left) + 25 + "px" }).addClass("option1"); } I am looking to loop through the list of positons in the list and draw multiple green boxs based on the positions on the screen. The above code draws just one green box from the last offset position.

XSL - How to match consecutive comma-separated tags

- by PocketLogic

I'm trying to match a series of xml tags that are comma separated, and to then apply an xslt transformation on the whole group of nodes plus text. For example, given the following partial XML: <p>Some text here <xref id="1">1</xref>, <xref id="2">2</xref>, <xref id="3">3</xref>. </p> I would like to end up with: <p>Some text here <sup>1,2,3</sup>.</p> A much messier alternate would also be acceptable at this point: <p>Some text here <sup>1</sup><sup>,</sup><sup>2</sup><sup>,</sup><sup>3</sup>.</p> I have the transformation to go from a single xref to a sup: <xsl:template match="xref""> <sup><xsl:apply-templates/></sup> </xsl:template> But I'm at a loss as to how to match a group of nodes separated by commas. Thanks.

How can I refactor these script tags?

- by Shpigford

I have the following script tags in the <head> so that they don't prompt any security errors when going back and forth between SSL and non-SSL pages. But it just looks hairy. Any way I can combine them or reduce some of the code? <script type="text/javascript">document.write(["\<script src='",("https:" == document.location.protocol) ? "https://" : "http://","ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js' type='text/javascript'>\<\/script>"].join(''));</script> <script type="text/javascript">document.write(["\<script src='",("https:" == document.location.protocol) ?

HTML dynamic tags insert looks different compared to static layout

- by Andrew Florko

I program HTML interface with jquery. There is editable list of publications on the page and user can click any publication to edit details. Popup window appears with data and there is list of authors embedded into details form. There are edit/delete buttons against every of them + "add new author" button. User manipulates authors without page reload. When I insert a new author there are new edit/delete buttons created dynamically & embedded into page. I insert tags like this: <td class="author-actions"> <img onclick='edit(id)' .../> <img onclick='delete(id)' .../> </td> Just the same html-layout that is sent from web-server when popup window appears. But somehow it looks different. There is extraspace between images though firebug demonstrates the same css attributes applied. If I select with mouse inserted layout with IE, somehow it can reorder and become the same-looklike as the those, send by web-server. What can it be?

Saving tags into a database table in CakePHP

- by Cameron

I have the following setup for my CakePHP app: Posts id title content Topics id title Topic_Posts id topic_id post_id So basically I have a table of Topics (tags) that are all unique and have an id. And then they can be attached to post using the Topic_Posts join table. When a user creates a new post they will fill in the topics by typing them in to a textarea separated by a comma which will then save these into the Topics table if they do not already exist and then save the references into the Topic_posts table. I have the models set up like so: Post model: class Post extends AppModel { public $name = 'Post'; public $hasAndBelongsToMany = array( 'Topic' => array('with' => 'TopicPost') ); } Topic model: class Topic extends AppModel { public $hasMany = array( 'TopicPost' ); } TopicPost model: class TopicPost extends AppModel { public $belongsTo = array( 'Topic', 'Post' ); } And for the New post method I have this so far: public function add() { if ($this->request->is('post')) { //$this->Post->create(); if ($this->Post->saveAll($this->request->data)) { // Redirect the user to the newly created post (pass the slug for performance) $this->redirect(array('controller'=>'posts','action'=>'view','id'=>$this->Post->id)); } else { $this->Session->setFlash('Server broke!'); } } } As you can see I have used saveAll but how do I go about dealing with the Topic data?

I am having trouble trying to get a group of li tags to align how I want. I have some basic html <div class="menu"> <ul> <li>Item 1</li> <li>Item 2</li> <li>Item 3</li> </ul> </div>? and some css .menu { border:solid 2px red; width:520px; } ul { border:solid 1px #e5e5e5; height:40px; margin:0 auto; list-style:none; width:500px; } li{ text-align:center; display:inline; margin:10px; } I dont want to hard code li widths for each of the elements but I would like for the li elements to take up all available space with the ul element.

Get href tags in html data in c#

- by Nani

I am using web client class to HTML data from a web page. Now I want to get the complete href tags and there titles from the HTML data. Initially I used loops, Felling inefficient I switched to regExp, but dint got efficient solution. He is the initial code: for (int i = 0; i < htmldata.Length - 5; i++) { if (htmldata.Substring(i, 5) == "href=") { n1 = htmldata.Substring(i + 6, htmldata.Length - (i + 6)).IndexOf("\""); Sublink = htmldata.Substring(i + 6, n1); var absoluteUri = new Uri(baseUri, temp); n2 = htmldata.Substring(i + n1 + 1, htmldata.Length - (i + n1 + 1)).IndexOf("<"); subtitle = htmldata.Substring(i + 6 + n1 + 2, n2 - 7); } } This code is getting some of the links like this. /l.href.replace(new RegExp( /advanced_search?hl=en&q=&hl=en& and titles like this onclick=gbar.qs(this) class=gb2Photos ")+"q="+encodeURIComponent(b)})}i.qs=n;function o(a,b,d,c,f,e){var g=document.getElementById(a);if(g){var Which are absolutely invalid. Please suggest me the correct code for getting valid relative href links and titles. ThankYou.

Create Extension Method to Produce Open & Closing Tags like Html.BeginForm()

- by DaveDev

Hi Guys I wonder if it's possible to create an extension method which has functionality & behaviour similar to Html.BeginForm(), in that it would generate a complete Html tag, and I could specificy its contents inside <% { & } %> tags. For example, I could have a view like: <% using(Html.BeginDiv("divId")) %> <% { %>  <% } %> This capability would be very useful in the context of the functionality I'm trying to produce with the example in this question This would give me the ability to create containers for the types that I'll be <% var myType = new MyType(123, 234); %> <% var tag = new TagBuilder("div"); %> <% using(Html.BeginDiv<MyType>(myType, tag) %> <% { %>   <div class="MyType" prop1="123" prop2="234">    </div> <% } %> I realise this will produce invalid XHTML, but I think there could be other benefits that outweigh this, especially since this project doesn't require that the XHTML validate to the W3C standards. Thanks Dave

Automatically Organize Tags in Tax/Folksonomy

- by Rob Wilkerson

I'm working on a process that will perform natural language processing (NLP) on one--and potentially several--of our content rich sites. What I'd like to do once the NLP is complete is to automatically organize the output (generally a set of terms that you might think of as tags given the prevalence of that metaphor) into some kind of standard or generally accepted organizational structure. In a perfect world, I'd really like this to be crowd sourced under the folksonomy concept (as opposed to a taxonomy) since the ultimate goal is to target/appeal to real people rather than "domain experts", but I'm open to ideas and best practices. For the obvious purpose of scalability, I'd like to automate the population of this tax/folksonomy so that "some guy" in the team/organization isn't responsible for looking at a bunch of words (with or without context) and arbitrarily fleshing out the contextual components of the tree. I have a few ideas for doing this that require some research to establish viability, but I have exactly zero practical experience with this sort of thing so the ideas really just boil down to stuff I made up that might perform some role in accomplishing the task. Imagining that others have vastly more experience with this sort of thing, I'm hoping that I can stand on your shoulders. Thanks for your thoughts and insights.

How to store arbitrary data for some HTML tags

- by nickf

I'm making a page which has some interaction provided by javascript. Just as an example: links which send an AJAX request to get the content of articles and then display that data in a div. Obviously in this example, I need each link to store an extra bit of information: the id of the article. The way I've been handling it in case was to put that information in the href link this: <a class="article" href="#5"> I then use jQuery to find the a.article elements and attach the appropriate event handler. (don't get too hung up on the usability or semantics here, it's just an example) Anyway, this method works, but it smells a bit, and isn't extensible at all (what happens if the click function has more than one parameter? what if some of those parameters are optional?) The immediately obvious answer was to use attributes on the element. I mean, that's what they're for, right? (Kind of). <a articleid="5" href="link/for/non-js-users.html"> In my recent question I asked if this method was valid, and it turns out that short of defining my own DTD (I don't), then no, it's not valid or reliable. A common response was to put the data into the class attribute (though that might have been because of my poorly-chosen example), but to me, this smells even more. Yes it's technically valid, but it's not a great solution. Another method I'd used in the past was to actually generate some JS and insert it into the page in a <script> tag, creating a struct which would associate with the object. var myData = { link0 : { articleId : 5, target : '#showMessage' // etc... }, link1 : { articleId : 13 } }; <a href="..." id="link0"> But this can be a real pain in butt to maintain and is generally just very messy. So, to get to the question, how do you store arbitrary pieces of information for HTML tags?

dumping the source code for an anonymous function

- by intuited

I'm working with a lot of anonymous functions, ie functions declared as part of a dictionary, aka "methods". It's getting pretty painful to debug, because I can't tell what function the errors are happening in. Vim's backtraces look like this: Error detected while processing function NamedFunction..2111..2105: line 1: E730: using List as a String This trace shows that the error occurred in the third level down the stack, on the first line of anonymous function #2105. IE NamedFunction called anonymous function #2111, which called anonymous function #2105. NamedFunction is one declared through the normal function NamedFunction() ... endfunction syntax; the others were declared using code like function dict.func() ... endfunction. So obviously I'd like to find out which function has number 2105. Assuming that it's still in scope, it's possible to find out what Dictionary entry references it by dumping all of the dictionary variables that might contain that reference. This is sort of awkward and it's difficult to be systematic about it, though I guess I could code up a function to search through all of the loaded dictionaries for a reference to that function, watching out for circular references. Although to be really thorough, it would have to search not only script-local and global dictionaries, but buffer-local dictionaries as well; is there a way to access another buffer's local variables? Anyway I'm wondering if it's possible to dump the source code for the anonymous function instead. This would be a lot easier and probably more reliable.

RegEx strip html tags problem

PHP: POST Request to ASP.NET website results in 500 server error when html tags included

- by RyanJD

My situation: I need to send text to an ASP.NET web service using POST. The entire page there is a form: <form name="aspnetForm" method="post" action="Discussion.aspx?classroom=lG39il1cotOAGJwiNvmQlIPfwmjikD%2fAHLhjjGInAZQ%3d&Page=Posts&ID=794239&Sort=&SortOrder=" id="aspnetForm"> So, I figured if I sent a POST request to this form with the correct inputs it would work. And, to an extent, it has. The form inputs are as follows: <input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" /> <input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" /> <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDw..." /> <input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="/wEWYQLrt..." /> And a bunch of other inputs. The code I have used is as follows: // grab form info $inputs = extract_form_inputs($discussion['body']); $inputs['__EVENTTARGET'] = 'ctl00$cphMain$ctl01$btnSubmit'; $inputs['ctl00$cphMain$ctl01$tbNickname'] = "Your Instructor"; $inputs['ctl00$cphMain$ctl01$reMessage'] = $message; // submit form $r = request_send($discussion['url'], $inputs); extract_form_inputs does exactly that. $discussion['body'] is the content of the page. $discussion['url'] is the URL of the page. request_send has two arguments: ($url, $post_array). It performs rawurlencode on each element of the array and joins them up as keypairs, in the same way as http_build_query. The request is url encoded properly, sent to the correct page, and works fine until I insert html tags. I have checked - the 'greater than' and 'less than' symbols ('<' and '') are url-encoded properly. However, the server responds with a 500 error. It accepts any other text. Has anyone else come across this sort of problem? Is there some setting on an ASP.NET server that denies html? I can't see this being the case - there is a rich text editor on the website that I am sending requests to. This text editor performs the same request as I am, only I am doing it remotely. The rich text editor sends html to the form - I have checked that, too, using javascript. Note: I do not have the power to modify the ASP.NET server.

Wordpress Custom Post Type adding tags

- by Nick White

I am currently working on a Wordpress site I have created some custom Post Types all work fine create the post etc. What I need however is custom taxonomies with some of the custom Post Types, I have set this up and when adding different tags to the taxonomy it works however, when creating a post for a custom post type in the taxonomy block clicking add tag it just does a anchor link to #Member news Category-add Nothing else happens, it's not a big bug but I would however, like to fix this so it is correct for the time I go live Is this a known bug? or is there something I have probably missed when creating the custom post type? register_post_type('member_news', array( 'label' => 'Member News','description' => 'News content submitted by members of RRUKA.','public' => true,'show_ui' => true,'show_in_menu' => true,'capability_type' => 'post','hierarchical' => false,'rewrite' => array('slug' => 'member-news'),'query_var' => true,'has_archive' => true,'exclude_from_search' => false,'menu_position' => 5,'supports' => array('title','editor','excerpt','trackbacks','revisions','thumbnail','author','page-attributes',),'labels' => array ( 'name' => 'Member News', 'singular_name' => 'Member News', 'menu_name' => 'Member News', 'add_new' => 'Add Member News', 'add_new_item' => 'Add New Member News', 'edit' => 'Edit', 'edit_item' => 'Edit Member News', 'new_item' => 'New Member News', 'view' => 'View Member News', 'view_item' => 'View Member News', 'search_items' => 'Search Member News', 'not_found' => 'No Member News Found', 'not_found_in_trash' => 'No Member News Found in Trash', 'parent' => 'Parent Member News', ),) ); Any information on this would be very welcome Thanks in advanced

Is there any "modern" text editor with command-line/minibuffer?

- by Pedro Morte Rolo

A command line in a text editor is a wonderful feature. It allows the user to explore the editor's functionality and learn it's shortcuts in a textual way. It's much faster than using the mouse, and it is much easier to memorise "shortcuts" this way. Emacs and VI provide this, though, emacs and vi are not "modern". By "modern", I mean one that is original built to cope with the modern de-facto standards of selecting, copying, pasting, cutting, undoing, redoing and auto-completing. Cream/vi or Emacs/CUA are not valid options, since there are loads of things built over them that conflict with the mentioned stuff. It would be nice if there was an editor that would cope with the modern de-facto standards out-off-the-box, but still provide a command-line/minibuffer to perform/explore the commands and learn its shortcuts. Is there such a thing? I do not intend to use the "modern" term as derrogatory. I love both Emacs and VI, but I hate their keyboard-shortcut historical baggage. When I reffer to de-facto standards, I am not talking about Windows vs Whatever. Kate, gedit, Eclipse, Intelij or Textmate also follow the norm I am talking about and are not Windows editors. Please do not advertise Vim and Emacs, that's not answering the question. I am asking for alternatives. Why don't I like emacs and vi: Emacs: Despite CUA mode, emacs has loads of modes that conflict with this (e.g. slime, ruby-mode, etc...) It would be nice to have something that would work out-off-the-box. VI: I do not like that it is Visual/Insert-based. I do not know how to browse the text-editor's commands. I do not like that it is so much tought for the terminal. I believe that it has the same problem that I mentioned for emacs. This question is starting to look like requirement analysis.. As de-facto standards I mean: Ctrol-XCV for cut-copy-paste Ctrol-A for select-all Contrl-Z for Undo Ctrol-Y for Redo Control-F for Searching Contrl-Space for auto-complete Shift-arrow for selection Control-arrow for word-navigation Alt-Arrow for moving

I am able to get the sorted but XMLListCollection but the problem is I got the <ename> collection sorted but I need the sorted <ename> in the XML. I tried with deleting the the item in Collection then adding the sorted list but in that case the <name> is lost. Please help me out in sorting <ename> or is there any way to specify nested tags in SortField name? Thanks in advance.

OmniCppComplete: Completing on Class Members which are STL containers

- by Robert S. Barnes

Completion on class members which are STL containers is failing. Completion on local objects which are STL containers works fine. For example, given the following files: // foo.h #include <string> class foo { public: void set_str(const std::string &); std::string get_str_reverse( void ); private: std::string str; }; // foo.cpp #include "foo.h" using std::string; string foo::get_str_reverse ( void ) { string temp; temp.assign(str); reverse(temp.begin(), temp.end()); return temp; } /* ----- end of method foo::get_str ----- */ void foo::set_str ( const string &s ) { str.assign(s); } /* ----- end of method foo::set_str ----- */ I've generated the tags for these two files using: ctags -R --c++-kinds=+pl --fields=+iaS --extra=+q . When I type temp. in the cpp I get a list of string member functions as expected. But if I type str. omnicppcomplete spits out "Pattern Not Found". I've noticed that the temp. completion only works if I have the using std::string; declaration. How do I get completion to work on my class members which are STL containers?

Senario: Add Item (Id 1) Add Item (Id 1) With a price change Void Item (Id 1) Void Item (Id 1) With a price change Add Item (Id 1) Add Item (Id 1) Expected Outcome Remove: Add Item (Id 1) Add Item (Id 1) With a price change Output XML Contains Void Item (Id 1) Void Item (Id 1) With a price change Add Item (Id 1) Add Item (Id 1) Input XML: <xml> <product void="false"> <sequence_number>1</sequence_number> <item_id>11111111</item_id> <price>12</price> </product> <product void="false"> <sequence_number>2</sequence_number> <item_id>11111111</item_id> <price>12</price> <price_change> <price>10</price> </price_change> </product> <product void="true"> <sequence_number>3</sequence_number> <item_id>11111111</item_id> <price>12</price> <price_change> <price>10</price> </price_change> </product> <product void="true"> <sequence_number>4</sequence_number> <item_id>11111111</item_id> <price>12</price> </product> <product void="false"> <sequence_number>5</sequence_number> <item_id>11111111</item_id> <price>12</price> </product> <product void="false"> <sequence_number>6</sequence_number> <item_id>11111111</item_id> <price>12</price> </product> </xml> Expected outcome: <xml> <product void="true"> <sequence_number>3</sequence_number> <item_id>11111111</item_id> <price>12</price> <price_change> <price>10</price> </price_change> </product> <product void="true"> <sequence_number>4</sequence_number> <item_id>11111111</item_id> <price>12</price> </product> <product void="false"> <sequence_number>5</sequence_number> <item_id>11111111</item_id> <price>12</price> </product> <product void="false"> <sequence_number>6</sequence_number> <item_id>11111111</item_id> <price>12</price> </product> </xml> XSLT <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:template match="//product[@void='false']"> <xsl:if test="item_id != //product[@void='true']/item_id"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:if> </xsl:template> </xsl:stylesheet> The problem with this is that it is deleting all products that are not voided and have the same id and not taking into account the number of void items vs the number of none void items. If you have 1 void item it should only delete one product that is not voided but has exactly the same tags as itself

ruby nl2br outside <code> ... </code>

- by Julien P.

Hi everyone, I've been struggling on this thing for a week without being able to find what I'm looking for. Here is what I'd like to do: I'm setting up a wiki where I can post all my knowledge to (yes, I know a couple things :p) but I can't render it the way I'd like to. The bodies of my posts are text fields. In order to render them the right way I run the following command: @post.body.gsub("\n", "<br />") I also have some tags with some code inside that looks like this < code my code < /code. Here come's the issue. Every line between the < code and < /code tags are changed to but it doesn'r render properly since I'm using a code render template. Therefore, I'd like to know if there is a way to change all \n to < br / except for those between < code and < /code Thank you everyone for reading this and helping me out. PS: Please do not consider the spaces after the < in each tag. I had to do this to "espace" them. Julien

Java: attributes order in .jsp getting inversed

- by NoozNooz42

Every single time I've read about the meta tags, the attribute where in this order for the description: <meta name="description" content="..." /> First name, then content. It's also like that in the Google Webmaster documentation. Basically, it's like that everywhere. Now in a .jsp (in XML notation) I've got the following: <meta name="description" content="${metadesc}"/> So it's name first, then content. Yet on the generated webpage, I get this: <meta content="...(200 chars or so here making it a very long line)..." name="description"/> Somehow the attributes have been inversed. Because the content follows the official W3C and Google recommendations, the content is a bit less than 200 characters long, which makes it a major pain to "visually verify" that the name attribute is correctly there (I've got to scroll). Anyway... Why are these attribute not appearing in the order defined in the .jsp? Can I force them to appear in the same order as I wrote them in my .jsp? I realize the resulting tag may be valid... But I can also imagine a lot of very creative ways to have valid tags which users would be very upset about. Does this make any sense to inverse these attributes? EDIT wow, just wow... If I invert the attributes in my .jsp (that is, writing them in the "wrong" order), then they appear as I want them to appear in the generated web page. (Tomcat 6.0.26 btw)

How to design data storage for partitioned tagging system?

- by Morgan Cheng

How to design data storage for huge tagging system (like digg or delicious)? There is already discussion about it, but it is about centralized database. Since the data is supposed to grow, we'll need to partition the data into multiple shards soon or later. So, the question turns to be: How to design data storage for partitioned tagging system? The tagging system basically has 3 tables: Item (item_id, item_content) Tag (tag_id, tag_title) TagMapping(map_id, tag_id, item_id) That works fine for finding all items for given tag and finding all tags for given item, if the table is stored in one database instance. If we need to partition the data into multiple database instances, it is not that easy. For table Item, we can partition its content with its key item_id. For table Tag, we can partition its content with its key tag_id. For example, we want to partition table Tag into K databases. We can simply choose number (tag_id % K) database to store given tag. But, how to partition table TagMapping? The TagMapping table represents the many-to-many relationship. I can only image to have duplication. That is, same content of TagMappping has two copies. One is partitioned with tag_id and the other is partitioned with item_id. In scenario to find tags for given item, we use partition with tag_id. If scenario to find items for given tag, we use partition with item_id. As a result, there is data redundancy. And, the application level should keep the consistency of all tables. It looks hard. Is there any better solution to solve this many-to-many partition problem?
