  • Shortest way of attaching multiple DOM elements to one event handler using Jquery?

    - by Camsoft
    I need to attach a single event handler to multiple DOM elements using jQuery. I'm currently achieving this using jQuery's each() method. See below: $([elm1, elm2, elm3]).each(function() { this.click(eventHandler); }); I was wondering if there is a way to do this without using the each method and closure. I thought I would be able to do something like: $(elm1, elm2, elm3).click(eventHandler); This kind of statement works using Prototype.js but not in jQuery.The reason I ask the question is because after using both Prototype.js and jQuery I have found that jQuery requires simpler statements to achieve the same tasks in almost every area so I assume there must be a better way of doing this?

  • Using PHP, how to parse the title and meta tags from a HTML page?

    - by Dylan Taylor
    Hey guys, I need to be able to get the TITLE and DESCIPTION metadata out of a page. I've been trying to do this but I've been getting more errors than actual results. (I have an array of about 10 URLS, usually only about 2 of them give me the descrption. I have yet to get the title). So how do I, in PHP, get the Desc and Title from a remote page, and if there is none or if there's an error, ignore it? -Dylan

  • validating creation by post_id and ip_address - Ruby on Rails

    - by bgadoci
    I have created a blog application using Ruby on Rails which includes the ability to vote on posts. A user can click vote and a record is created in the vote table. I am now trying to limit that same person from voting for a post multiple times. class Post has_many :votes end class Vote belongs_to :post end When a vote record is created I am using the VotesController to pass the :post_id and using a hidden field in the view to pass the ip_address (both to the vote table). I am wondering if there is a way to add a validation to the Vote Model that searches to see if a post_id has an ip_address that matches the person requesting to vote. I have tried simply using the validates_uniqueness_of :ip_address but that restricts the user from voting on any post. I just want to restrict the user from voting on a particular post that they have already voted on. Is there a way to do this through validation?

  • Flash, parameters, security

    - by Quandary
    Hi, I have a question: In Flash, I have the ability to save certain info onto the server. Now the problem is the user needs to be authenticated as admin in order to do so. I can't use sessions, since if you work longer than 20 minutes in the Flash application, the session is gone. The way I see it, I have 2 possibilities: 1. passing a parameter (bIsAdmin) to Flash from the Website. 2. Launch a http-get request, to get this value (bIsAdmin) from an ashx handler on application startup, when the session has not yet exired. In my opinion, both possibilities are not really secure... So, Which one is safer, 1 or 2? Or does anybody have a better idea ? In my opinion, 1 is safer, because with 2, you can just switch a packet tamperer in between, and bang, you're admin, with permission to save (or overwrite, =delete) anything.

  • Chat Service / Server for ASP.NET

    - by denisb
    I'm looking to have a livechat service integrated within a site where I can create chat rooms on the fly based on participants tied to that specific area... Anyone recommend using a 3rd party service I can install on the server that integrated easily with .NET, or just build one using polling method? I'd like something with socket connection, but not sure what's out there that either cheap or free that I can use.

  • JQuery: Push Effect?

    - by JGreig
    I'm currently using the JQuery slideDown/slideUp effect and am not accomplishing what I want. Essentially, I want to create an action where I "push" a div off the top of the browser window. Something similar to the following push effect example. How can I do this with JQuery? The problem with just using slideDown/slideUp is that the other DIV just overlaps the div I'm hiding. But instead, I want to PUSH the div I don't want visible off the top of the browser window.

  • How is the iPad going to be classified - as a mobile platform or a desktop platform?

    - by Tony Eichelberger
    I sometimes use the following site to look at browser and OS trends http://gs.statcounter.com/. It got me thinking about how the iPad is going to be classified, as a mobile platform or a desktop platform, or is it going to spark a new category. Since it runs iPhone OS, it could be considered a mobile device, but I have a hard time with that because of the screen size. What should iPad be classified as: Mobile, Desktop, or Other (Try to come up with a good name for Other)?

  • Best Static Website Generator

    - by Nick Retallack
    In the age of dynamic websites built with layouts and templates, nobody wants to write plain old repetitive static html anymore. But now that you can outsource dynamic features to services like Disqus, and you could get slashdotted/dugg/reddited at any moment, sometimes a static website is best for scalability. There are quite a few static website generators out there that let you use templates, layouts, alternative markup languages, and other new age stuff. So this question is a bit of a survey. Which do you think is the best, and why? Here are a few examples to start us off: WebGen StaticMatic Static

The service were published online on a server, with public access, right now I can see the wsdl from any computer, but when trying to consume it with PHP it shows me an error that says something about HTTP header and blablabla, that happened before I connected with a VPN to the server where the service is being hosted, after doing the VPN just by curiosity I reloaded the php client, and I don't know why... It did worked.... Q: Can anybody tell me why did this happened?

  • HttpParsing for hypertext

    - by Nani
    I am in process of getting all hierarchical links from a given link and validating them; This is the code I wrote. But I am not feeling it as efficient. Reasons are: 1.For the non unique links which open same page, code is getting sub-links again and again 2.Is the code getting all links? 3.Is it making valid URLs from the sub-links it derived? 4.May be some other reasons about which I have no idea. Please suggest me how to make this piece of code efficient . Thank you. class Program { public static ArrayList sublink = new ArrayList(); public static ArrayList subtitle = new ArrayList(); public static int ini = 0, len_o, len_n, counter = 0; static void Main(string[] args) { // Address of URL string URL = "http://www.techonthenet.com/"; sublink.Add(URL); l: len_o = sublink.Count; len_o); Console.WriteLine("-------------Level:" + counter++); for (int i = ini; i < len_o; i++) test(sublink[i].ToString()); len_n = sublink.Count; if (len_o < len_n) { ini = len_o; goto l; } Console.ReadKey(); } //method to get the sub-links public static void test(string URL) { try { // Get HTML data WebClient client = new WebClient(); Stream data = client.OpenRead(URL); StreamReader reader = new StreamReader(data); string str = "", htmldata = "", temp; int n1, n2; str = reader.ReadLine(); while (str != null) { htmldata += str; str = reader.ReadLine(); } data.Close(); 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("\""); temp = htmldata.Substring(i + 6, n1); if (temp.Length > 4 && temp.Substring(0, 4) != "http") { if(temp.Substring(0,1)!="/") temp=URL.Substring(0,URL.IndexOf(".com/")+5)+temp; else temp = URL.Substring(0, URL.IndexOf(".com/") + 5) + temp.Remove(0,1); } if (temp.Length < 4) temp = URL.Substring(0, URL.IndexOf(".com/") + 5) + temp; sublink.Add(temp); n2 = htmldata.Substring(i + n1 + 1, htmldata.Length - (i + n1 + 1)).IndexOf("<"); subtitle.Add(htmldata.Substring(i + 6 + n1 + 2, n2 - 7)); i += temp.Length + htmldata.Substring(i + 6 + n1 + 2, n2 - 7).Length; } } for (int i = len_n; i < sublink.Count; i++) Console.WriteLine(i + "--> " + sublink[i]); } catch (WebException exp) { Console.WriteLine("URL Could not be Resolved" + URL); Console.WriteLine(exp.Message, "Exception"); } } }

  • Any tool available to detect what's not HTTPS on an encrypted page?

    - by Keltex
    More often than I like when designers edit some of our sites' pages, they include javascript or an external image our SSL pages that are not encrypted. For example if we have a page like this: https://www.example.com/cart/EnterCreditCard And the designer includes some non-encrypted image like this: <img src='http://www.cardprocessor.com/logo.gif' /> Of course, this creates errors in all browsers: IE: Do you want to view only the webpage content that was delivered securely? Firefox: Connection Partially Encrypted Chrome: (I forget this message) What I'm looking for is a tool or plugin that lets me easily see what objects are not encrypted. A firefox extension or something along those lines would be great.

  • Action Mailer Confirmation Emails - Ruby on Rails...

    - by bgadoci
    I have successfully installed the Clearance Gem from ThoughtBot. Clearance sends a confirmation email upon a new sign_up and suggests adding: config.action_mailer.default_url_options = { :host => 'localhost:3000' } to your /environments/test.rb and development.rb. I have tried this and also config.action_mailer.default_url_options = { :host => '127.0.0.1', :port => 3000 } But can't seem to get rails to send the email. As I am new to both Ruby and Rails, I am wondering if there is some step/config that ThoughtBot is assuming I have already done to send emails. What am I doing wrong/missing? UPDATE: Just added notifier.rb class Notifier < ActionMailer::Base recipients recipient.email_address_with_name bcc ["[email protected]"] from "[email protected]" subject "New account information" body :account => recipient end end

  • How to find a coding buddy

    - by Lirik
    I was reading Jeff Atwood's blog and he mentioned that he was suffering from code-paralysis (he called it analysis paralysis, but I feel like it's also code paralysis) when he didn't have a code buddy: http://www.codinghorror.com/blog/ Unfortunately I think that Jeff has set the bar a bit high, because he only works with developers who are really amazing. The only reason really amazing developers would work with me is if I was really amazing too, but sometimes I don't feel that amazing... the only thing I feel is that if I had a coding buddy I could be amazing :). I'm working on a project and I don't have many friends that are programmers, let alone friends that have time to spend on extracurricular activities. Jeff seems to have been able to find like-minded people that are actually willing to work together. I feel like I'm in a code-paralysis stage too and I need some coding buddies, where would I find some? How would I approach them?
