  • JQuery: Read each line of an element

    - by Sarfraz
    Hello, Suppose I have this html markup: <div id="wrapper"> $(function(){ // hide all links except for the first $('ul.child:not(:first)').hide(); $("a.slide:first").css("background-color","#FF9900"); $('ul.parent a.slide').click(function(){ $('ul.parent a.slide').css("background-color","#3399FF"); $('ul.parent a.slide').mouseout(function(){ $(this).css("background-color","#3399FF"); }); $('ul.parent a.slide').mouseover(function(){ $(this).css("background-color","#66CC66"); }); }); }); </div> What is the easiest way to read each line of code present in the div. How do I extract each line of code from that div or loop over each line styling in any way I want. Thanks

  • S3 browser upload via POST: unable to handle errors gracefully

    - by samf
    I am writing an app where I want the customer to be able to upload to Amazon S3 straight from the browser. I can make this work just fine. But when errors occur, I want to handle them more gracefully than splattering an XML document on the customer's screen. I have a scheme that I think would work, but it's failing. Here's what I'm trying: Create a form to do the upload, and store the form on S3 itself, in the same domain as the "action" attribute of the form. Redirect the customer to this form. Now their browser is sitting on https://<bucket>.s3.amazonaws.com/something. The page contains a hidden iframe. The form sets its target to the iframe. The load event handler looks at the contents of the iframe, and acts upon it. So, something like this: <iframe id="foo" name="foo" style="display: none" /> <form target="foo" action="https://<bucket>.s3.amazonaws.com/"> <input type="hidden" name="..." value="..." /> <input type="file" name="file" /> </form> with this javascript (using jquery): function handler() { var message = $("#foo").contents().find('message').text(); alert(message); } $("#foo").load(handler); Using firebug, I can see that the iframe contains an XML document, that contains a "message" node. However, the .find('message') always fails to find anything within the XML document. Notice that the action of the form has the same domain, port, and scheme as the document itself. So, I don't think that I should be running afoul of the same-origin policy. Right? But it fails every time. This is using Firefox and Google Chrome browsers. Thanks for any advice!

  • The Wheel Invention - Beneficial For Learning?

    - by Sarfraz
    Hello, Chris Coyier of css-tricks.com has written a good article titled Regarding Wheel Invention. In a paragraph he says: On the “reinventing” side, you benefit from complete control and learning from the process. And on the very next line he says: On the other side, you benefit from speed, reliability, and familiarity. Also often at odds are time spent and cost. He is right in both statements I think. I really like his first statement. I do actually sometimes re-invent the wheel to learn more and gain complete control over what I am inventing. I wonder why people are so much against that or rather biased. Isn't there the benefit of learning and getting complete control or probably some other benefits too. I would love to see what you have to say about this.

  • Image Replacement (JS/JQuery) working in IE but not FF

    - by Sunburnt Ginger
    I have tried multiple solutions for replacing broken images (both JS & jQuery) and all work perfectly with IE but not in FF, is there a reason for this? Are images handled differently in FF that may cause this? JQuery Example: $("img").error(function(){ $(this).unbind("error").attr("src", "nopic.jpg"); }); Javascript Example: (triggered by onError event in img tag) function noimage(img){ img.onerror=""; img.src="nopic.jpg"; return true; } Both of these examples work perfectly in IE but not at all in FF. What gives? Thanks in advance!

  • As a programmer, what are some telltale signs that you're about to get fired or laid off?

    - by plaureano
    If you have ever been fired from a job, did you notice anything different about the behavior of your peers or upper management just before your termination? What are some common signs to look for among your coworkers and project manager(s) that would indicate your position is severely at risk? EDIT: My instincts were right, and I opted to resign rather than face termination. I guess when you have that "gut feeling" that something is about to happen, it's a strong sign that you should be heading for the exit...

  • Slick PHP based image manager for managing user profile images

    - by franko75
    Hi, I'm just throwing this out there as I'm plodding my way through creating a Member Photo album on a site i'm working on, where they can login and upload their photos to a personal gallery. I want this to be nice and lightweight, but still slick and "modern" with a modal based interface for the user. I'm surprised though that there is seemingly nothing open source out there which fits the bill - I've done a few searches on Google to no avail and can't seem to find anything. Lots of bloated photo galleries out there but nothing looks like it has been developed using more recent technologies. Is anyone aware of anything which might suit what I'm looking for? I'm fully prepared to try and code it myself but I'd be delighted if I didn't have to! Pure laziness you might say, but there's no point reinventing the wheel.

  • Would you work for an "Adult" Company?

    - by Ender
    Although I try to distance myself from web-oriented work nowadays (unless I need the money) I've received a number of emails from clients wishing for me to help design and develop online solutions for adult websites. Hell, when I was 17 I was asked to help design an adult website that I would not legally be able to view. After talking to a few Software Engineers and Flash Developers I have heard that there is a lot of interesting work in the adult industry for those who like to work with new technologies. Have any of you worked for a company dealing with adult/pornographic content? Did you enjoy it? If you haven't would you ever consider it? More than anything I find it interesting to see how others would view the offer, whether you would be afraid to list it on a CV/Resume, how interesting the work would be, how you think future employees would see you and whether you believe that they would judge you for working in a dirty industry.

  • Visual Studio 2008 - Assemblies are not loaded into Modules after relocating the website and project

    - by user296861
    I recently moved the asp.net website solution folder (along with class projects) to different location. As the result, visual studio doesn't stop at break points, and I could not able to debug. I see none of my assemblies at Debug Windows Modules; only microsoft assemblies are loaded. I have also deleted all bin folder and re-referenced all projects. But still no luck. Thanks in advance!

  • Widget_Controller for different types of data (MVC)

    - by steve-o
    Hello, I have a few widgets I need to show on a site - they are all relating to different types of data (e.g user, house). Each type of data and its relations is represented in specific models, but as far as a controller or helper is concerned, is it an ok plan to have a generic Widget controller/helper which generates the necessary widgets, even though each widget is dealing with distinct data? I don't really want to generate these widgets within the User and House controllers, as these controllers are dealing with different types of functionality. I'd imagine that the Widget_Controller could just contain static methods for generating these widgets, e.g: Widget_Controller::user_panel(); Does that make sense? Cheers!

  • What is the standard way of using a sitemap with pages that require specific information passed to t

    - by Mike
    Hi, I have a website for which many pages rely on information passed to them (usually in the form of a querystring) or on a session variable. When making a web application, how do you normally handle these particular pages in regards to the sitemap? If you're using the standard ASP.NET menu control, it will render the node on the menu and if you click it, you could get an exception stating that a session variable doesn't exist (if it hasn't been created yet). For example, if you're making a user management area: All of these nodes get rendered, but I don't want the user to click on edit user or delete user without specifying someone to edit or delete. Any tips or suggestions would be greatly appreciated.

  • What's the easiest and safest way to record data being inputted by a user on a web site

    - by fred august
    Apologies, this is a tragically simple question that will bore most of you. I need to implement the simplest "leave your email and we'll contact you" web page. The simplest thing I could think of is doing an HTML form which calls a PHP script which appends the data in some file on the server. Easy to implement, but now I'm wondering if it's totally hackable. Is it? Are there obvious better ways that are still simple? thanks f

  • why does django-registration use an "activation window" for activating accounts?

    - by bharal
    i'm using django-registration, which is a django lib that helps with users registering on a django-built website. All well and dandy, except that it insists i have an "activation email" associated with all new users. It defaults to a 7 day window, after which, if someone signed up (and we then sent an email to confirm their email address) but didn't click on the link in the sent email within the 7 days, then they cannot sign up. Instead, they need to do the whole process all over again. I'm sure this is a concept that exists generally in web design, because why would django-registration make its own arbitrary signup process up? Anyway, the question is why? What do i gain by having the peace of mind knowing that all the users of my site are the kind of go-getters that click on registration emails with 7 days of receiving them? Why should i sleep easier knowing that my database isn't filled with users who, for whatever reason, clicked through to sign up but didn't actually want to sign up? cheers!

  • 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?

  • What's wrong with the architecture of a game object drawing and updating itself?

    - by Ricket
    What are the reasons for and against a game object drawing and updating itself? For example, if you have a game where the player has a position on screen, why not have an all-encompassing class: public class Player { private int x, y, xVelocity, yVelocity; private Sprite s; //... public Player() { // load the sprite here, somehow? } public void draw(CustomGraphicsClass g) { g.draw(s, x, y); } public void update(long timeElapsed) { x += (xVelocity * timeElapsed); y += (yVelocity * timeElapsed); } } What is wrong with this design? What are the downfalls or concerns? How would you better write something like this, or better architect this type of thing in a game? Also, somewhat connected, how would you implement loading that Sprite image? And furthermore, how would you then implement collision between two Players? (I should probably separate these extra two questions into new questions, huh?)

  • Passing XML data and user from coldfusion page to .NET page

    - by Mark Rullo
    I'd appreciate some input on this situation, I can't figure out the best way to do this. I have some data that's being prepared for me in a ColdFusion app and in an IFrame within the CF app we want to display some graphs (not strictly an image, it's an entire page) being generated on the .NET side of things. I'd like to pass XML data from the CF side to .NET as well as the user. On the .NET side I'm putting the data in a session so the user can sift through it without the need to have it re-queried and re-passed from CF. What I've tried: Generating XML with CF, putting it in a hidden form field, auto-submitting (with JS) a the form to the .NET side. The issue I'm having with this approach is the encoding being done on the form post. The data has entries like <entry data="hello &amp; goodbye">. It's an issue because it's being URL encdeded, Posted, and when I get it on the .NET side I get <entry data="hello & goodbye"> which isn't properly formed XML. What I'd like to avoid: An intermediary DB approach (dropping the data in a DB on CF, picking it up with .NET) I'd like to only display what is passed to the page. I have security concerns with the data, it's very sensitive. Passing the data to a webservice, returning a GUID, forwarding the user with a URL Parameter to access the passed in data. I think that'd be risky if someone happened on a link to that data. I can't take that risk. I was thinking of passing the data with JSON, but I'm very unfamiliar with it. Thoughts? Thanks for your time folks.
