  • Changing color of a row in dropdown list

    - by Judy
    is it possible to change "selector" color in drop-down list? <select name="select" style="background-color: #ff0000"> <option style="background-color: #ff0000" value="1">Red</option> <option style="background-color: #ffffff" value="2">Green</option> <option style="background-color: #0000ff" value="3">Blue</option> </select> I tried in above style but it didn't worked. I know with javascript getting document.getElementById('text').style.color='red' can set the color. But is it possible in html to set the colors?

  • [PHP/MySQL] How to create text diff web app

    - by Adam Kiss
    Hello, idea I would like to create a little app for myself to store ideas (the thing is - I want it to do MY WAY) database I'm thinking going simple: id - unique id of revision in database text_id - identification number of text rev_id - number of revision flags - various purposes - expl. later title - self expl. desc - description text - self expl . flags - if I (i.e.) add flag rb;65, instead of storing whole text, I just said, that whenever I ask for latest revision, I go again in DB and check revision 65 Question: Is this setup the best? Is it better to store the diff, or whole text (i know, place is cheap...)? Does that revision flag make sense (wouldn't it be better to just copy text - more disk space, but less db and php processing. php I'm thinking, that I'll go with PEAR here. Although main point is to open-edit-save, possiblity to view revisions can't be that hard to program and can be life-saver in certain situations (good ideas got deleted, saving wrong version, etc...). However, I've never used PEAR in a long-time or full-project relationship, however, brief encounters in my previous experience left rather bad feeling - as I remember, it was too difficult to implement, slow and humongous to play with, so I don't know, if there's anything better. why? Although there are bazillions of various time/project/idea management tools, everything lacks something for me, whether it's sharing with users, syncing on more PCs, time-tracking, project management... And I believe, that this text diff webapp will be for internal use with various different tools later. So if you know any good and nice-UI-having project management app with support for text-heavy usage, just let me know, so I'll save my time for something better than redesigning the weel.

  • Web developement learning env

    - by David Oneill
    I am currently learning Ruby on Rails. I currently do all my development on my laptop. However, I know in all "real world" situations, I will be connecting to a dedicated server that will hold the site. So here is my question: what are the pros and cons of developing on the machine I use vs running the website on a separate server?

  • How can I [simply] consume JSON Data in a Line of Business Web Application

    - by Atomiton
    I usually use JSON with jQuery to just return a string with html. However, I want to start to use Javascript objects in my code. What's the simplest way to get started using json objects on my page? Here's a sample Ajax call ( after $(document).ready( { ... }) of course: $('#btn').click(function(event) { event.preventDefault(); var out = $('#result'); $.ajax({ url: "CustomerServices.asmx/GetCustomersByInvoiceCount", success: function(msg) { // // Iterate through the json results and spit them out to a page? // }, data: "{ 'invoiceCount' : 100 }" }); }); My WebMethod: [WebMethod(Description="Gets customers with more than n invoices")] public List<Customer> GetCustomersByInvoiceCount(int? invoiceCount) { using (dbDataContext db = new dbDataContext()) { return db.Customers.Where(c => c.InvoiceCount >= invoiceCount); } } What gets returned: {"d":[{"__type":"Customer","Account":"1116317","Name":"SOME COMPANY","Address":"UNit 1 , 392 JOHN ST. ","LastTransaction":"\/Date(1268294400000)\/","HighestBalance":13922.34},{"__type":"Customer","Account":"1116318","Name":"ANOTHER COMPANY","Address":"UNIT #345 , 392 JOHN ST. ","LastTransaction":"\/Date(1265097600000)\/","HighestBalance":549.42}]} What I'd LIKE to know, is what are people generally doing with this returned json? Do you iterate through the properties and create an html table on the fly? Is there way to "bind" JSON data using a javascript version of reflection ( something like the .Net GridView Control ) Do you throw this returned data into a Javascript Object and then do something with it? An example of what I want to achieve is to have an plain ol' html page ( on a mobile device )with a list of a Salesperson's Customers. When one of those customers are clicked, the customer id gets sent to a webservice which retrieves the customer details that are relevant to a sales person. I know the SO talent pool is quite deep so I figured you all here would be able to guide in the right direction and give me a few ideas on the best way to approach this.

  • How to merge or copy anonymous session data into user data when user logs in?

    - by benhoyt
    This is a general question, or perhaps a request for pointers to other open source projects to look at: I'm wondering how people merge an anonymous user's session data into the authenticated user data when a user logs in. For example, someone is browsing around your websites saving various items as favourites. He's not logged in, so they're saved to an anonymous user's data. Then he logs in, and we need to merge all that data into their (possibly existing) user data. Is this done different ways in an ad-hoc fashion for different applications? Or are there some best practices or other projects people can direct me to?

  • Java EE Module Dependencies in web project?

    - by Sled
    Hey guys, I have this webprojec to which I have to add a jar from another EJB project. Normally I'd right-click the webproject and go to properties - Java EE Module Dependencies. I don't know if it is because I upgraded eclipse, or i'm doing something wrong, but I just can't find the "Java EE Module Dependencies" in the properties window. Both projects are linked with the same EAR so the EJB jar file shuld be there! Any ideas what I'm doing wrong or some other way I could attach the EJB's JAR file? I'm only allowed to work with eclipse, so netbeans is not an option. Thanks! EDIT: basically, this is what I want to do, but that specific panel won't show up...

  • Best practice to detect iPhone app only access for web services?

    - by Gaius Parx
    I am developing an iPhone app together with web services. The iPhone app will use GET or POST to retrieve data from the web services such as http://www.myserver.com/api/top10songs.json to get data for top ten songs for example. There is no user account and password for the iPhone app. What is the best practice to ensure that only my iPhone app have access to the web API http://www.myserver.com/api/top10songs.json? iPhone SDK's UIDevice uniqueueIdentifier is not sufficient as anyone can fake the device id as parameter making the API call using wget, curl or web browsers. The web services API will not be published. The data of the web services is not secret and private, I just want to prevent abuse as there are also API to write some data to the server such as usage log.

  • Separate web and email host

    - by user871993
    My client has their domain name (lorem.com) registered with company X which also host their email. I'd like to host their new website with separate hosting company (company Y). I know I need to update the DNS nameservers for their domain name to point to company Y's nameservers. I'm not sure how to handle the email host though. Doing an MX lookup on their domain, currently shows: Pref Hostname 10 lorem.com 20 mx2.companyX.com Do I need to do any updates to the MX record? Also, do I need to add/edit the A record to point to company Y's IP address? Thanks!

  • How to store a 250mb database in an Offline Web App

    - by Couto
    Ok, maybe i'm not seeing the whole picture or something, but i kinda need a brainstorm. So the purpose is to make a webapp (HTML5, CSS, Javascript) that has to search on a 250mb database without any internet connection, so.. yes the database has to be on the client side. The hard part here is, this App has to work on an iPod or iPhone without internet connection. (An initial connection to download the App is ok), LocalStorage has a 5mb limit, couchDB would be great since they have an webapp easily accessed by Javascript (privacy concerns don't matter at this point), so i'm pretty much out of ideas.... Does anyone see an alternative, or solution for the purpose?

  • Hash passwords before transmitting? (web)

    - by wag2639
    I was reading this Ars article on password security and it mentioned there are sites that "hash the password before transmitting"? Now, assuming this isn't using an SSL connection (HTTPS), a. is this actually secure and b. if it is how would you do this in a secure manor? Edit 1: (some thoughts based on first few answers) c. If you do hash the password before transmission, how do you use that if you only store a salted hash version of the password in your user credentials databas? d. Just to check, if you are using a HTTPS secured connection, is any of this necessary?

  • Loading jQuery multiple times in the same page

    - by Winaji
    I'm implementing a plug-in that's embeddable in different sites (a la Meebo, Wibiya), and I want to use jQuery. Problem is, the site I'm embedding to, may already have a jQuery script loaded. The question is, what's the best approach for this kind of problem: Should I just check if jQuery is already loaded and if so, use the original site's jQuery, otherwise load it myself? If I use this approach, am I not risking comaptibility problems (i.e. the site uses an old version of jQuery)? Should I load jQuery myself (whether it's already loaded or not) and call "jQuery.noConflict(true)" when it's finished loading? If so, how can I make sure that my jQuery has finished loading (hooking to the onLoad event doesn't seem to work all the time, and polling for "jQuery" won't work for obvious reasons)? Should I do something else? Thanks.

  • Web hosting a setup where both Windows and Linux are required

    - by lk
    I have a system where a website needs to be hosted on a Linux machine while a backend application that the site talks to needs to reside on Windows. Is there any "common practice" for such hosting? Note - both of the systems are mine so there is the dilemma of whether to have the machines physically located together to avoid delay for calls over the net.

  • Web scrapping from a Google Chrome extension

    - by limoragni
    I've started to develop a Chrome extension to navigate and prform actions on a website. Until now the extension is able to receive a couple of parameters and check a set of radio-buttons, fill in a few inputs of a form and then submit it. What I want to do now is to repeat the process, but I'm stuck when the page is reloaded. And I don't know how can I do to make the script reacts to the finish of the request. The workflow I want to achieve is the following (is for automaticly copying a certain object): Popup side Enter the number of the Master object to copy Enter the base name of the copies (example Mod, so the I can iterate and add mod1, mod2, modn) Enter the number of copies Background side Select master Select standard options Fill in inputs Submit form Wait for the page to complete the request and continue to the next copy. (here I need help) The problem is on the repetition, the rest is taking care of. I assume that must be a way of dealing with requests. Any ideas? By the way I'm doing it all with the extension and tabs methods of google chrome plus javascript and jquery.

  • Drupal and Back-End Complexity

    - by Brian
    Currently I am working on a school website, and we are still in the decision-making process of choosing a framework (we know that we're not using Joomla! or hand-coding). Drupal came up as a viable choice, and currently, that is my best bet for the site. However, I have an issue with CMS's in general. I would like to develop a quite complicated and specifically custom-suited back-end application for teachers to interact with individual students, including the design of shared/custom calendars, announcement privileges, etc. I currently have a bit of expertise with HTML, CSS, PHP, MySQL, and I could wrap my head around some JavaScript and AJAX stuff if need-be. However, would such a complicated application work with Drupal (in that I could create it to specifically suite my purposes)?

  • Understanding configuration for parallel calling in web app (IIS + MS SQL)

    - by mmcteam.com.ua
    We have an ASP.NET MVC application + IIS 7.5 + SQL Server 2008 R2. We have to load a lot of aggregate counters on the each page. We decided to use ajax and call with javascript for each counter or groups of counters and return them as JSON result. We solve the problem that user doesn't wait for page loading, page loads fast. User waits for counters loading while seeing other page content. But we thought that if we make calls from javascript - our queries will be make async, but we notice, that it is not. All our javascipt calls runs immediately, but action that they invoke are in queue. If we use Async Controller ability - all counters calculating simultaneously, but user has to wait for the longest counter calculating before page loads. The question: We want to understand what is happens if we use ajax and call two or more actions simultaneously. And how can we configuring this. (also in each action we make some queries to sql server)

  • A simple, clean web layout

    - by Shaun_web
    Ok, so I hate CSS/HTML graphic design... What do you guys recommend as a sample template or website that you think has great CSS and html layout? From my past experience it's best to get a page that has a white background and little dependency on graphics -- that's clean, and easy to modify ;-).
