  • Find all html characters in drop-down option text and replace them via jQuery

    - by Jon Harding
    I have a dropdown menu that pulls in text from a database column. The database column can include HTML mark-up. In the drop-down I obviously don't need that in the text. I am working on some jquery and it partially accomplished what I'm looking for. However, it seems to only be replacing the first instance of each character $('select option').each(function() { this.text = this.text.replace('&nbsp;', ' '); this.text = this.text.replace('<div>', '' ); this.text = this.text.replace('</div>', '' ); }); Here is the HTML for the drop-down: <select name="ctl00$SubPageBody$ClassList" id="ctl00_SubPageBody_ClassList"> <option value="196">Four Week Series: July 19, 2012, 11:00am-12:00pm&<div>July 26, 2012, 11:00am-12:00pm&nbsp;</div><div>August 2, 2012, 11:00am-12:00pm</div><div>August 9, 2012, 11:00am-12:00pm</div></option> </select>

  • Java: Tracking a user login session - Session EJBs vs HTTPSession

    - by bguiz
    If I want to keep track of a conversational state with each client using my web application, which is the better alternative - a Session Bean or a HTTP Session - to use? Using HTTP Session: //request is a variable of the class javax.servlet.http.HttpServletRequest //UserState is a POJO HttpSession session = request.getSession(true); UserState state = (UserState)(session.getAttribute("UserState")); if (state == null) { //create default value .. } String uid = state.getUID(); //now do things with the user id Using Session EJB: In the implementation of ServletContextListener registered as a Web Application Listener in WEB-INF/web.xml: //UserState NOT a POJO this this time, it is //the interface of the UserStateBean Stateful Session EJB @EJB private UserState userStateBean; public void contextInitialized(ServletContextEvent sce) { ServletContext servletContext = sce.getServletContext(); servletContext.setAttribute("UserState", userStateBean); ... In a JSP: public void jspInit() { UserState state = (UserState)(getServletContext().getAttribute("UserState")); ... } Elsewhere in the body of the same JSP: String uid = state.getUID(); //now do things with the user id It seems to me that the they are almost the same, with the main difference being that the UserState instance is being transported in the HttpRequest.HttpSession in the former, and in a ServletContext in the case of the latter. Which of the two methods is more robust, and why?

  • assignment vs std::swap and merging and keeping duplicates in seperate object

    - by rubenvb
    Say I have two std::set<std::string>s. The first one, old_options, needs to be merged with additional options, contained in new_options. I can't just use std::merge (well, I do, but not only that) because I also check for doubles and warn the user about this accordingly. To this effect, I have void merge_options( set<string> &old_options, const set<string> &new_options ) { // find duplicates and create merged_options, a stringset containing the merged options // handle duplicated the way I want to // ... old_options = merged_options; } Is it better to use std::swap( merged_options, old_options ); or the assignment I have? Is there a better way to filter duplicates and return the merged set than consecutive calls to std::set_intersection and std::set_union to detect dupes and merge the sets? I know it's slower than one traversal and doing both at once, but these sets are small (performance is not critical) and I trust the Standard more than I trust myself.

  • self.window.rootViewController vs window addSubview

    - by Gazzer
    I've noticed a lot of examples for iPhone apps in the Application Delegate - (void)applicationDidFinishLaunching:(UIApplication *)application have [window addSubview: someController.view]; (1) as opposed to self.window.rootViewController = self.someController; (2) Is there any practical reason to use one over the other? Is one technically correct? Do controller's have the an equivalent command to number (2) like self.someController.rootController = self.someOtherController; // pseudocode

  • Sun webstack vs Installing PHP, MySQL, Apache individually

    - by Vincent
    Is it possible to install PHP, MySQL, Apache individually on Solaris instead of installing them through a webstack? What are the advantages and disadvantages? I seem to frequently get a CURL error on Solaris when dealing with HTTPS sites. (error:81072080:lib(129):func(114):reason(128). I have no clue why that error is occuring and thought it might solve it, if I upgrade to latest PHP,MySQL,Apache versions. At this point I am not even sure if it's a Solaris issue. Any advice? Thanks

  • Stateless singleton VS Static methods

    - by Sebastien Lorber
    Hey, Don't find any good answer to this simple question about helper/utils classes: Why would i create a singleton (stateless) rather than static methods? Why an object instance could be needed while the object has no state? Sometimes i really don't know what to use...

  • align li tags with an auto width vs hard coding

    - by Diver Dan
    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. What do I need to change to get the result I am looking for? My attempt on jsfiddle

  • MacOSX: OSAtomic vs OSAtomicBarrier

    - by anon
    For the functions here: #include <libkern/OSAtomic.h> there are OSAtomic and OSAtomicBarrier versions. However, the documentation does not show sample code for: When is it safe to use just OSAtomic, without the OSAtomicBarrier version When is it that OSAtomic would be unsafe, but OSAtomiBarrier would be safe. Can anyone provide explainations + sample codes? [Random ramblings of "your opinion" without actual code is useless. Readers: please down vote such answers; and vigrously upvote answers with actual code.] [C/C++ code preferred; Assembly okay too.]

  • Pros & Cons: Hibernate vs. EJB 3

    - by Zack
    What are the advantages and disadvantages of Hibernate & EJB3 relative to each other? I found this post, but it didn't really address my question. If I don't have any particular tie to either technology, what would cause me to pick one over the other? Or are there situations where I would want to use both? Thanks, Zack

  • URIs vs Hidden Forms

    - by NateDogg
    I'm working in the Codeigniter framework, and want to send requests to my controller/model that have several variables involved. Is there a difference between passing those variables via a hidden form (i.e. using "post") as opposed to passing them through URIs (e.g. 'travel/$month/$day/')? What about security concerns? e.g. URIs: http://www.example.com/travel/$month/$day/ Hidden Form: form_hidden('month',$month); form_hidden('day',$day);

  • Force VS to use System.[Type] in Code Completion

    - by James
    Is it possible to have Visual Studio code completion use the System.[Type] instead of the keyword. Example: Autocomplete of List<String> myList = completes as: List<String> myList = new List<string>(); whereas, I want: List<String> myList = new List<String>(): This isn't the only example, but hopefully shows what I'm looking for.

  • Zend Framework Relations vs. Table Select

    - by rtmilker
    Hey! I just want to know your guys opinion on using join tables within the zend framework. Of course you can use relations by defining a referenceMap and dependentTables and stuff, or using setIntegrityCheck(false) within a db select(). The setIntegrityCheck version seems a little bit dirty to me, but the other version is not very suitable for big querys and joining many tables... I'm a PHP developer for 5 years now and new to the zend framework and just want get a direction for my first project. Thanks!!!

  • C++ arrays as parameters, subscript vs. pointer

    - by awshepard
    Alright, I'm guessing this is an easy question, so I'll take the knocks, but I'm not finding what I need on google or SO. I'd like to create an array in one place, and populate it inside a different function. I define a function: void someFunction(double results[]) { for (int i = 0; i<100; ++i) { for (int n = 0; n<16; ++n) //note this iteration limit { results[n] += i * n; } } } That's an approximation to what my code is doing, but regardless, shouldn't be running into any overflow or out of bounds issues or anything. I generate an array: double result[16]; for(int i = 0; i<16; i++) { result[i] = -1; } then I want to pass it to someFunction someFunction(result); When I set breakpoints and step through the code, upon entering someFunction, results is set to the same address as result, and the value there is -1.000000 as expected. However, when I start iterating through the loop, results[n] doesn't seem to resolve to *(results+n) or *(results+n*sizeof(double)), it just seems to resolve to *(results). What I end up with is that instead of populating my result array, I just get one value. What am I doing wrong?

  • Icons in Silverlight: Images vs. Vectors

    - by Shnitzel
    I like using the vector drawing feature of Expression Blend to create icons. That way I can change colors easily on my icons without having to resort to an image editor. But my question is... Say I have a treeview control that has an icon next to each tree element and say I have hundreds of elements. Do you think using images is faster - performance wise than using vector icons? B/c I'd rather use vectors but I'm wondering about performance concerns.

  • VS 2008 and F# Feb CTP - Can't debug

    - by Steve
    I have downloaded the VS2008 integrated shell, and the F# Feb CTP and I have the F# environment working just fine. The problem comes when I try to debug. Nothing happens at all. The output window says ------ Build started: Project: ConsoleApplication1, Configuration: Debug Any CPU ------ ========== Build: 1 succeeded or up-to-date, 0 failed, 0 skipped ========== and none of my breakpoints are hit. My "program" is as simple as can be #light open System printfn "Hello World" Console.ReadKey(true) with breakpoints on the printfn and Console lines. The things I've read seem to suggest that debugging would work with this setup, and there is a debugger folder under common7/packages with files in it. Thanks for any help. EDIT: I'm on Win7 64 bit

  • HTML input text box vs CakePHP Automagic Form Elements

    - by kwokwai
    Hi all, I was manually creating a simple form with one input text box field like this: <form action="/user/add" method="post"> <input type="text" name="data[user_id]" value="1"> But when I call $this->model->save($this->data) in the Controller, nothing was saved to the Table. Only when I used this and the data in the field was written to the database successfully: $form->create(null, array('url' => '/user/add')); echo $form->input('user_id', array('label' => 'User ID', 'value' => '1'));

  • Sql Server Replication: Snapshot vs Merge

    - by Zyphrax
    Background information Let's say I have two database servers, both SQL Server 2008. One is in my LAN (ServerLocal), the other one is on a remote hosting environment (ServerRemote). I have created a database on ServerLocal and have an exact copy of that database on ServerRemote. The database on ServerRemote is part of a web application and I would like to keep it's data up-to-date with the data in the database ServerLocal. ServerLocal is able to communicate with ServerRemote, this is one-way traffic. Communication from ServerRemote to ServerLocal isn't available. Current solution I thought it would be a nice solution to use replication. So I've made ServerLocal a publisher and subscriptions are pushed to the ServerRemote. This works fine, when a snapshot is transfered to ServerRemote the existing data will be purged and the ServerRemote database is once again an exact replica of the database on ServerLocal. The problem Records that exist on ServerRemote that don't exist on ServerLocal are removed. This doesn't matter for most of my tables but in some of my tables I'd like to keep the existing data (aspnet_users for instance), and update the records if necessary. What kind of replication fits my problem?

  • C# VS 2008 Build Configurations - using different classes for different builds

    - by evan
    I'm writing an application which has two classes that provide basically the same functionality but for different situations. I'd like to have three versions of the software - one where the user can change an ini file to configure the program to use one of the two classes, and then one version that only uses one of the two classes. Right now I have it working via an ini file, but I'd like to be able to build versions that don't include the code for the unneeded class at all. What is the best way to go about this? My current line of thinking is that since both classes derive from a common interface I'll just add a compile time conditional that looks at the active build configuration and decides whether to compile that class. What is the syntax to do that? Thanks in advance for your help and input!

  • view-port resize vs document resize in IE

    - by mkoryak
    window.resize event in IE doesnt do what i thought it does. I thought it only triggered when the physical window/view-port changed size (ie user hits maximize on the browser window for example), but it is also triggered if i change the document size, introducing scroll bars. is there any way to tell those two things apart: view port resize, and document resize without writing an elaborate hack?
