  • jquery load links not clickable

    - by john morris
    ok i am loading a separate page with links in it, into a page named index.php. it loads fine, but when i click one of the links inside the loaded content, nothing happens. they dont act as links. but if i do a alert('hi'); after the load('page.html'); then it will work. any ideas on getting this to work without alerting something after it loads? oh also i cant use a callback, unless there is a way to update the get variable because the page loading, has a $_GET variable, and the links inside the loaded page are supposed to update the $_GET variable. anyways is there a way to make the links clickable after loading the page?

  • jQuery returning two elements for each one it finds?

    - by John Rudy
    I'll start by saying I'm fairly new to jQuery. For the most part, I've found it intuitive and powerful, but this one circumstance has me thoroughly stumped. In the following method, the call to .each() returns two elements for every one found. It iterates over a set of table rows given IDs starting with the word, "communication," and followed by an ID number. For each row it returns, it processes twice. Using Firebug, I've validated that the DOM only has a single instance of each table row in question. Also using Firebug, I've validated that the method is not being called twice; the iteration in .each() is truly going over each returned table row twice. By the time all the AJAX call goodness is done, I'll have two entries in the database for each row created in the table. This is the code that's causing the issues: function getCommunications() { var list = $('[id^=communication]'); var communications = new Array(); list.each(function () { var communication = { ID: $(this).find('.commCompanyID').val(), /* * SNIP: more object properties here that are * unnecessary to this discussion */ }; communications.push(communication); }); return communications; } At the point of return communications, the Array returned will contain twice as many elements as there are table rows. I should note that nearly identical code (but going against specific lists of divs) is working on the same page. It's just the table that's suffering the issues. I'm using jQuery 1.4.1, the version which shipped with Visual Studio .NET 2010. The table markup is fully dynamic -- that is, aside from the header row, it's dependent on data either returned at page load or created by the user via a dialog box. I'll drop in just the code for what's created at page load; again using Firebug I've validated that what I create dynamically when an end user creates a row with the dialog box matches. (This should be readable by anyone, but for the record this is an ASP.NET MVC 2.0 project.) <table id="commTable"> <tr> <th></th> <th> Date / Time </th> <th> Contact </th> <th> Type </th> <th> Duration </th> <th> Notes </th> </tr> <% foreach (var item in Model) { %> <tr id="communication<%: item.ID %>"> <td> <a href="#" onclick="showEditCommunicationForm(<%: item.ID %>"> Edit</a> <span class="commDeleteButton"> <a href="#" onclick="deleteCommunication(<%: item.ID %>)"> Delete</a> </span> </td> <td> <span class="commDateTime"><%: item.DateTime %></span> <input type="hidden" class="commID" value="<%: item.ID %>" /> <input type="hidden" class="commIsDeleted" value="<%: item.IsDeleted %>" /> </td> <td> <span class="commSourceText"><%: item.Company.CompanyName %></span> <input type="hidden" class="commCompanyID" value="<%: item.CompanyID %>" /> </td> <td> <%: item.CommunicationType.CommunicationTypeText %> <input type="hidden" class="commTypeID" value="<%: item.CommunicationTypeID %>" /> </td> <td> <span class="commDuration"><%: item.DurationMinutes %></span> Minutes </td> <td> <span class="commNotes"><%: item.Notes %></span> </td> </tr> <% } %> </table>

  • All words in a trie data-structure

    - by John Smith
    I'm trying to put all words in a trie in a string, a word is detonated by the eow field being true for a certain character in the trie data structure, hence a trie can could have letters than lead up to no word, for ex "abc" is in the trie but "c"'s eow field is false so "abc" is not a word Here is my Data structure struct Trie { bool eow; //when a Trie field isWord = true, hence there is a word char letter; Trie *letters[27]; }; and here is my attemped print-all function, basically trying to return all words in one string seperated by spaces for words string printAll( string word, Trie& data) { if (data.eow == 1) return word + " "; for (int i = 0; i < 26; i++) { if (data.letters[i] != NULL) printAll( word + data.letters[i]->letter, *(data.letters[i])); } return ""; } Its not outputting what i want, any suggestions?

  • What's the official Microsoft way to track counts of dynamic controls to be reconstructed upon Postback?

    - by John K
    When creating dynamic controls based on a data source of arbitrary and changing size, what is the official way to track exactly how many controls need to be rebuilt into the page's control collection after a Postback operation (i.e. on the server side during the ASP.NET page event lifecycle) specifically the point at which dynamic controls are supposed to be rebuilt? Where is the arity stored for retrieval and reconstruction usage? By "official" I mean the Microsoft way of doing it. There exist hacks like Session storage, etc but I want to know the bonafide or at least Microsoft-recommended way. I've been unable to find a documentation page stating this information. Usually code samples work with a set of dynamic controls of known numbers. It's as if doing otherwise would be tougher. Update: I'm not inquiring about user controls or static expression of declarative controls, but instead about dynamically injecting controls completely from code-behind, whether they be mine, 3rd-party or built-in ASP.NET controls.

  • Benefits of migrating my work to a new web development framework?

    - by John
    When I first started programming with PHP, I was ignorant of other php frameworks (like code igniter, cake php, etc...). So I fell into the trap of re-inventing wheels, which had the benefit of being "fun" and "educational". Overtime, I discovered other open source products that I found useful, like smarty templating engine, jquery library, tcpdf library, fdf etc...so I started bundling these technologies along with things I've built over the years into a LAMP development framework to make life easier for myself. This pass year, I've been having fun developing on the code igniter framework. It does many of the things I do in my framework. Coding in CI feels natural because the MVC and ORM feels similar to the MVC and ORM of my framework. So now I'm contemplating migrating a lot of the plugins in my framework over to CI. The pros and cons I can think of for such a project are: Pros: benefit from the vast community of CI developers lots of other developers will be familiar with it better documentation Cons: I've built a lot of useful plugins against my own framework, and it will take a lot of time to move even just the essential ones at the moment, I still, work faster against my own framework than CI, just because I'm more familiar with it even if I did migrate to CI, there will always be newer and better frameworks in the near future, and i'll be contemplating this scenario again So my question is the following: perhaps I should leave my old framework as is, and for each new project I receive, I make a decision on whether the requirements are best served by developing with CI or my own framework. Is this the right approach?

  • I want to combine my www and non www and keep the link jucie from both.

    - by John Ray
    My website shows up for some keywords in the www and some in the non www. Seaquake shows more links to the non www version. It is a PR2 either way. I would like to combine the link juice of the two versions into the non www version. Does anyone know the best way to combine the two and keep the link juice of both. It is as simple as a 301 redirect and if so does the 301 need to be handled in any specific way.

  • Alternative to BerkeleyDB?

    - by John
    I'm looking for a dbm-like library that I can use in place of Berkeley DB, which I'm currently using. My main reason for switching is the licensing fees for BDB are pretty high (free for open source apps, but my employer does not want to open source this particular app for various reasons). I've looked briefly at qdbm but it doesn't look like it will fill my needs -- lots of keys (several million) and large data items ( 1-5 megabytes). Before I continue my search I figured I'd ask because it seems there are tons of dbm-like libraries out there.

  • unable to get into windows 7 or ubuntu after system file back on a dual boot system

    - by John Jiang
    I installed ubuntu on my dell xps 9000 which originally has a window 7 installed. So after I did system file back up as told by windows 7 and restarted my computer, I received the following message right after restarting in the black screen: roughly like this: ubuntu grub error, " " symbol cannot be found. I was wondering how I can get access into windows 7 and uninstall ubuntu all together. I actually had the same booting problem after system backup before and the solution was to install two extra ubuntus but I'd prefer not to do that. I'd highly appreciate any help!

  • How Do You Profile & Optimize CUDA Kernels?

    - by John Dibling
    I am somewhat familiar with the CUDA visual profiler and the occupancy spreadsheet, although I am probably not leveraging them as well as I could. Profiling & optimizing CUDA code is not like profiling & optimizing code that runs on a CPU. So I am hoping to learn from your experiences about how to get the most out of my code. There was a post recently looking for the fastest possible code to identify self numbers, and I provided a CUDA implementation. I'm not satisfied that this code is as fast as it can be, but I'm at a loss as to figure out both what the right questions are and what tool I can get the answers from. How do you identify ways to make your CUDA kernels perform faster?

  • .hgignore whole directory tree excepting one specific file

    - by John Mee
    Can anyone tell me the .hgignore pattern to track one specific file in a directory and to ignore everything else? I have a "media" directory which contains a "default.png", for obvious purposes, and the rest of the directory will hold user media. We want hg to ignore everything in the media directory excepting the default file.

  • How to update a custom dependency property when the datasource list changes

    - by John
    Hi We have a user control with a custom dependency property (DP). The DP is bound to an ObservableCollection. When a new item is added to the collection programatically, the databinding does not update the target DP. Why? We think it's because, unfortunately, in our case the target is not a ListBox or ListView, but a Canvas. The DP, when changed or initialized, is supposed to draw a Shape (!) onto the Canvas, and the shape's position and size is bound to the collection item's two properties: WIDTH, LEFT. Ideally we don't want to clear the Canvas and redraw all items just becasue one has been added (or deleted). But how? So: How can the custom DP take care of drawing the shape for the new collection item? What callback do we need, at what point in time does this have to happen, and what specific MetaDataOptions might there? Also, are there any good resources out there concerning all these dependency property options. They are quite confusing. MSDN does not really help with what we're trying to do. Thanks!

  • UNIX-style RegExp Replace running extremely slowly under windows. Help? EDIT: Negative lookahead ass

    - by John Sullivan
    I'm trying to run a unix regEXP on every log file in a 1.12 GB directory, then replace the matched pattern with ''. Test run on a 4 meg file is took about 10 minutes, but worked. Obviously something is murdering performance by several orders of magnitude. Find: ^(?!.*155[0-2][0-9]{4}\s.*).*$ -- NOTE: match any line NOT starting 155[0-2]NNNN where in is a number 0-9. Replace with: ''. Is there some justifiable reason for my regExp to take this long to replace matching text, or is the program I am using (this is windows / a program called "grepWin") most likely poorly optimized? Thanks. UPDATE: I am noticing that searching for ^(155[0-2]).$ takes ~7 seconds in a 5.6 MB file with 77 matches. Adding the Negative Lookahead Assertion, ?=, so that the regExp becomes ^(?!155[0-2]).$ is causing it to take at least 5-10 minutes; granted, there will be thousands and thousands of matches. Should the negative lookahead assertion be extremely detrimental to performance, and/or a large quantity of matches?

  • Conventions for the behavior of double or triple "click to select text" features?

    - by John Sullivan
    Almost any mature program that involves text implements "double click to select the word" and, in some cases, "triple click to select additional stuff like an entire line" as a feature. I find these features useful but they are often inconsistent between programs. Example - some programs' double clicks do not select the ending space after a word, but most do. Some recognize the - character as the end of a word, others do not. SO likes to select the entire paragraph as I write this post when I triple click it, VS web developer 2005 has no triple click support, and ultra-edit 32 will select one line upon triple clicking. We could come up with innumerable inconsistencies about how double and triple click pattern matching is implemented across programs. I am concerned about how to implement this behavior in my program if nobody else has achieved a convention about how the pattern matching should work. My question is, does a convention (conventions? maybe an MS or Linux convention?) exist that dictates how these features are supposed to behave to the end user? What, if any, are they?

  • Temporary users table or legitimate users table?

    - by John
    I have a freelance web application that lets users register for events. In my database, I have a t_events_applicants table with the column t_events_applications.user_id with a foreign key constraint linked to the t_users.user_id column. So this means only users who have registered with my web application can register for my web application's events. My client would now like to allow non-registered users, users who do not have an entry in my t_user table, to register for events. These non-registered users only need to provide their name and email address to register for events. Should I create a t_temporary_user table with columns name and email and then remove the t_events_applicants.user_id fk constraint? Or should I add un-registered users to the t_user table and then add a column called t_user.type where type can be 'registered' or 'non-registered'? How do I decide which approach to go with? A lot of times, I hesitate with either approach. I ask myself, "What if at a later time, a temporary user is allowed to become a fully registered user? Then maybe I should have only a t_user table. But then I also don't feel good about storing a lot of temporary users in t_user."

  • DB2 ZOS String Comparison Problem

    - by John
    I am comparing some CHAR data in a where clause in my sql like this, where PRI_CODE < PriCode The problem I am having is when the CHAR values are of different lengths. So if PRI_CODE = '0800' and PriCode = '20' it is returning true instead of false. It looks like it is comparing it like this '08' < '20' instead of like '0800' < '20' Does a CHAR comparison start from the Left until one or the other values end? If so how do I fix this? My values can have letters in it so convering to numeric is not an option.

  • How can I send an automated reply to the sender and all recipients with Procmail?

    - by jchong
    I'd like to create a procmail recipe or Perl or shell script that will send an auto response to the original sender as well as anybody that was copied (either To: or cc:) on the original email. Example: [email protected] writes an email to [email protected] and [email protected] (in the To: field). Copies are sent via cc: to [email protected] and [email protected]. I'd like the script to send an auto response to the original sender ([email protected]) and everybody else that was sent a copy of the email ([email protected], [email protected], [email protected] and [email protected]).

  • How would you go about parsing markdown?

    - by John Leidegren
    You can find the syntax here. The thing is, the source that follows with the download is written in perl. Which I have no intentions of honoring. It is riddled with regex and it relies on MD5 hashes to escape certain characters. Something is just wrong about that! I'm about to hard code a parser for markdown and I'm wonder if someone had some experience with this? Edit: If you don't have anything meaningful to say about the actual parsing of markdown, spare me the time. (This might sound harsh, but yes, I'm looking for insight, not a solution i.e. third-party library). To help a bit with the answers, regex are meant to identify patterns! NOT to parse an entire grammar. That people consider doing so is foobar. If you think about markdown, it's fundamentally based around the concept of paragraphs. As such, a reasonable approach might be to split the input into paragraphs. There are many kinds of paragraphs e.g. heading, text, list, blockquote, code. The challenge is thus to identify these paragraphs and in what context they occur. I'll be back with a solution, once I find it's worthy to be shared.
