  • How do I do client-side form validation in jQuery?

    - by marcamillion
    I am trying to use this plugin: http://docs.jquery.com/Plugins/Validation Where #user_new is the id for my form, this is what my code looks like: $('#user_new').validate({ rules: { user[username]: "required", user[email]: { required: true, email: true } }, messages: { user[username]: "Please specify your name", user[email]: { required: "We need your email address to contact you", email: "Your email address must be in the format of [email protected]" } } }) Where these are how my input fields look when the page is rendered (generated by Rails): <input class="clearField curved" id="user_f_name" name="user[f_name]" size="30" type="text" value="First Name" /><br /> <input class="clearField curved" id="user_l_name" name="user[l_name]" size="30" type="text" value="Last Name" /><br /> <input class="clearField curved" id="user_username" name="user[username]" size="30" type="text" value="Username" /><br /> <input class="clearField curved" id="user_password" name="user[password]" size="30" type="password" value="Password" /><br /> <input class="clearField curved" id="user_password_confirmation" name="user[password_confirmation]" size="30" type="password" value="Password" /><br /> <input class="clearField curved" id="user_email" name="user[email]" size="30" type="text" value="Email Address" /><br /> I was just trying to validate username & email first. Then take it from there. For the life of me, I can't figure out how to specify the syntax and the rules for working with this plugin. Help!

  • ValidateRequest ="false" for single input

    - by ajbeaven
    I'm wanting to allow users to enter HTML in only a single textbox. I understand it's possible to change ValidateRequest in the Page directive to false in order to remove protection. I'm guessing that this allows HTML to be entered in any textbox on the page. Is there anyway to apply ValidateRequest=False on only a single control? Thanks for any help.

  • Suggest changes to make the time a function of input size

    - by KB
    Vector v; int i=0; while(i!=999) { cini; v.push_back(i); } Time taken by this piece of code could vary when the number of inputs vary. Since vector would take amortized time for new allocation. Even for same size the program at different times could take different time. Suggest changes (e.g. use list instead of vector), which makes the time a function of number of inputs.

  • Some input regarding Dojo (smooth css change on mouseover)

    - by Andy Walpole
    I've been playing around with Dojo over the last couple of days. The script below changes the background position of the list item when the mouse is over the link. dojo.query('a[class=main-menu-link]').forEach(function(linkTwo) { dojo.connect(linkTwo, "onmouseover", function(evt) { dojo.query('#main-menu ul li').forEach(function(linkThree) { dojo.style(linkThree, { "backgroundPosition": "right center", }); }); You can see it in action in the right hand side menu: http://www.mechanic-one.suburban-glory.com/ I'm trying to work out the best of way of giving it a smooth transition between the two states... I've been looking on the Dojo documentation page but I'm not sure what is the best way of approaching it.

  • How do I lex this input?

    - by etheros
    I currently have a working, simple language implemented in Java using ANTLR. What I want to do is embed it in plain text, in a similar fashion to PHP. For example: Lorem ipsum dolor sit amet <% print('consectetur adipiscing elit'); %> Phasellus volutpat dignissim sapien. I anticipate that the resulting token stream would look something like: CDATA OPEN PRINT OPAREN APOS STRINGAPOS CPARENT SEMI CLOSE CDATA How can I achieve this, or is there a better way?

  • 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.

  • C++'s unordered_map / hash_map / Google's dense_hash - how to input binary data (buf+len) and insert

    - by shlomif
    Hi all, I have two questions about Google's dense_hash_map, which can be used instead of the more standard unordered_map or hash_map: How do I use an arbitrary binary data memory segment as a key: I want a buffer+length pair, which may still contain some NUL (\0) characters. I can see how I use a NUL-terminated char * string , but that's not what I want. How do I implement an operation where I look if a key exists, and if not - insert it and if it does return the pointer to the existing key and let me know what actually happened. I'd appreciate it if anyone can shed any light on this subject. Regards, -- Shlomi Fish

  • Play! 1.2.5 with mongodb | Model Validation not happening

    - by TGV
    I have a simple User model whose fields are annotated with play validation annotations and morphia annotations like below. import play.data.validation.*; import play.modules.morphia.Model; import com.google.code.morphia.annotations.*; @Entity public class User extends Model{ @Id @Indexed(name="USERID", unique=true) public ObjectId userId; @Required public String userName; @Email @Indexed(name="USEREMAIL", unique=true) @Required public String userEmail; } Now I have a service which has a CreateNewUser method responsible for persisting the data. I have used Morphia plugin for the dao support. But the problem is that User Document gets persisted in mongo-db even if userName or userEmail is NULL. Also @Email validation does not happen // Below code is in app/controllers/Application.java User a = new User(); a.userName = "user1"; // calling bean to create user, userService is in app/service/UserService userService.createNewUser(a); It does not work even after adding @valid and validation.hasErrors() check.Below code is in app/service/UserService public void createNewUser(@Valid User user) { if (Validation.hasErrors()) { System.out.println("has errors"); } else { // TODO Auto-generated method stub userDao.save(user); } }

  • Microphone input

    - by George
    I'm trying to build a gadget that detects pistol shots using Android. It's a part of a training aid for pistol shooters that tells how the shots are distributed in time and I use a HTC Tattoo for testing. I use the MediaRecorder and its getMaxAmplitude method to get the highest amplitude during the last 1/100 s but it does not work as expected; speech gives me values from getMaxAmplitude in the range from 0 to about 25000 while the pistol shots (or shouting!) only reaches about 15000. With a sampling frequency of 8kHz there should be some samples with considerably high level. Anyone who knows how these things work? Are there filters that are applied before registering the max amplitude. If so, is it hardware or software? Thanks, /George
