  • traits in php – any real world examples/best practices?

    - by Max
    Traits have been one of the biggest additions for PHP 5.4. I know the synatax and understand the idea behind traits, like horizontal code re-usage for common stuff like logging, security, caching etc. However, I still dont know yet how I would make use of traits in my projects. Are there any open source projects that already use traits? Any good articles/reading material on how to structure architectures using traits?

  • Is there a Silverlight equivalent to "Application.OpenForms"?

    - by lightmeetsdark
    Basically, I'm trying to take information entered by the user on one page and print it out to another page via a "printer friendly" version, or report, of something. I have a MainPage.xaml that is, as the name suggests, my main page, but in a window there is the subpage AdCalculator.xaml where the user enters the information and PrintEstimate.xaml that is navigated to via a button on AdCalculator. I would like to be able to transfer the information entered in the textboxes from AdCalculator and print it out via text blocks in PrintEstimate. So in order to do that I have the following code: Views.AdCalculator AdCalc = new Views.AdCalculator(); string PrintCompanyName = AdCalc.CompanyName; string PrintContactName = AdCalc.txt_CustomerName.Text; string PrintBillingAddress1 = AdCalc.txt_BillingAddress.Text; string PrintBillingAddress2 = AdCalc.txt_BillingAddressLine2.Text; string PrintPhoneNumber = AdCalc.txt_PhoneNumber.Text; string PrintNumOfAds = AdCalc.txt_NumofAds.Text; string PrintRateOfPlay = AdCalc.Cmb_Rate.SelectedValue.ToString(); string PrintNumOfMonths = AdCalc.txt_NumofMonths.Text; string PrintTotalDue = AdCalc.txt_InvoiceSummary_TotalDue.Text; PrintEstimate PrintEstimatePage = new PrintEstimate(); PrintEstimatePage.txt_CompanyName.Text = PrintCompanyName; PrintEstimatePage.txt_CustomerName.Text = PrintContactName; PrintEstimatePage.txt_BillingAddress.Text = PrintBillingAddress1; PrintEstimatePage.txt_BillingAddressLine2.Text = PrintBillingAddress2; PrintEstimatePage.txt_PhoneNumber.Text = PrintPhoneNumber; PrintEstimatePage.txt_InvoiceSummary_NumofAds.Text = PrintNumOfAds; PrintEstimatePage.txt_InvoiceSummary_RateofPlay.Text = PrintRateOfPlay; PrintEstimatePage.txt_InvoiceSummary_NumOfMonths.Text = PrintNumOfMonths; PrintEstimatePage.txt_EstimateTotal.Text = PrintTotalDue; Only problem is, when I instantiate the new AdCalculator page, it clears the values, so nothing is actually retained as far as user-input goes. Following a lead from a colleague, I believe all I need to do is change the line Views.AdCalculator AdCalc = new Views.AdCalculator(); to Views.AdCalculator AdCalc = (AdCalculator)Application.OpenForms["AdCalculator"]; except the "Apllication.OpenForms" doesn't register. I know there are a lot of differences in the way C# code-behind is laid out for silverlight applications, so I didn't know if there was an equivalent that anyone knew about to "Application.OpenForms" that would help solve my issue or if there was any other way to go about getting my task done. Thank you very much!

  • Redirecting users in JSP from within a includes - java syntax error

    - by Mark Hazlett
    Hey everyone, So my setup for my web application is that I have a general header and footer and then I just include them in all my other pages so that all the common elements for all the pages are in a single page. The only problem I'm running into is when I want to redirect the user back to a login page if the "username" session has not already been created. The problem that I"m running into is that I have an if statement at the top of my header.jsp and then I have the else in the footer.jsp and it is giving me a java syntax error. Any ideas? Here is the code I'm referring to... <%@page contentType="text/html" pageEncoding="UTF-8"%> <% if(session.getAttribute("username") != null) { %> <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <!-- CSS files --> <link rel="stylesheet" href="../CSS/headerStyle.css" type="text/css" media="screen" /> <title>Insert title here</title> </head> <body> <div id="container"> <div id="header"> <div id="headerTitle">Title</div> </div> </div> <%} %> And then here is the footer <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <link rel="stylesheet" href="../CSS/headerStyle.css" type="text/css" media="screen" /> </head> <body> <div id="footer"></div> </body> </html> <% else { response.sendRedirect("../wa_login/login.jsp"); } %> However it is giving me an error on the else statement because the else doesn't have an if statement because it's in the header file.

  • jQuery: if value is true without user action

    - by Kevin Brown
    I want to show a div if the value of an input =='CP'. Right now this is my code: $(".register-type").change(function(){ var value = $(this).val(); if(value == 'CP'){ $('.cp-show').show(); This works fine if they change the input, but if things get validated false and the page reloads, this input is still 'CP', but the div doesn't show... Is there a way to correct this so that jquery checks if this is set on the page load?

  • jquery document height reported incorrectly by IE (on XP) first time

    - by Zhami
    I'm having a "first time" problem with IE, which reports a different value for $(document).height(); when the page first loads versus subsequent queries. The difference is 17 pixels regardless of the opening size of the window -- on document ready, the height reported is 17 pixels larger than is subsequently reported. I wonder if this is an artifact of some aspect of my page (some margins or paddings somewhere), but so far can't account for 17 pixels.

  • Using KnockoutJS 2.2.0 & jQuery 1.8.2 remove all bindings from all children of #someDiv

    - by Nukeface
    I'm wanting to delete All bindings (ko.cleanNode) from all child elements of a certain div. Must be a noobie question but I can't figure out how to use jQuery to loop through all childre, grand-children, great-grand-children, etc. whilst having KnockoutJS remove the bindings of all the DOM elements. I do NOT want to remove the elements from the DOM. This is a single page application, therefore the elements are pre-loaded as embedded resources and don't get resend to a client if they were to visit the page again. If a client revisits that part of the application I'll have a function rebind the necessary elements, which currently works fine. Current setup: <html> <head> //loading all resources </head> <body> //load first element using some obscure setup <div id="firsPage" data-role="page"> <div data-role="header">@Global.header</div> <div data-role="fieldcontain"> <label for="firstInput" /> <input id="firstInput some other stuff /> </div> <div data-role="datebox <!-- some settings --> > //creates table using jQuery mobile (lots of (great-)(grand-)children) </div> <div data-role="fieldcontain"> <div id="secondInput"> <div class="checklist"> <ul> <li /> <li /> </ul> </div> </div> </div> </div> //Here the whole thing starts again <div id="secondPage" data-role="page"> <!-- repeat above innerHTML in your mind ;) --> </div> //And here again! and again... </body> The problem I'm having is that bindings of the children don't seem to get "cleaned up" when i use ko.cleanNode($('#firstPage')[0]); Or when I get the Element into a variable and then format it to ko.cleanNode($element). Is there a way to do this? Been staring at it for a good few hours now, so probably overlooking a way too obvious way of doing it... Thanks!

  • Watir question regarding select_list and reloading

    - by AJ
    I have a drop down with multiple options. Whenever you choose an option, the page reloads with data specific with that option. Currently I'm using select.list(:name, strg).set(value) and it does that part just fine, but it does not reload the page with the specific data. Anyone know how to help. When i watch it in action, it doesn't select the option either, but my logs show that it does.Thanks.

  • Is it abuse to put application/business logic inside of jQuery plugins?

    - by RenderIn
    Is it appropriate to create jQuery plugins which are specific to a single page? I've been creating generic plugins that are not tied to any context and contain no business logic, but some people I've talked to suggest that almost all javascript, including business logic and logic specific to a single page, should be inside of jQuery plugins. Is it appropriate to have a validateformXYZ plugin which validates a specific HTML form? I'm buying into jQuery 100% but am not sure if this is a misuse or not.

  • ASP.NET MVC routing and paths is js files

    - by HiveHicks
    Hello, we're facing a problem now. We have a pretty big page with a loooong inline script, which does all the work. We now want to obfuscate it and use it as a separate .js file. But the problem is that we have paths which are generated by Url helper (Url.Content()). So what is the best way to separate js file from the page and not using hard-coded path strings?

  • Is there a better way to write this URL Manipulation in Python?

    - by dnolen
    I'm curious if there's a simpler way to remove a particular parameter from a url. What I came up with is the following. This seems a bit verbose. Libraries to use or a more pythonic version appreciated. parsed = urlparse(url) if parsed.query != "": params = dict([s.split("=") for s in parsed.query.split("&")]) if params.get("page"): del params["page"] url = urlunparse((parsed.scheme, None, parsed.path, None, urlencode(params.items()), parsed.fragment,)) parsed = urlparse(url)

  • IE7 and 8 Hangs Randomly on CSS Images

    - by BJ Safdie
    We have an ASP.NET 3.5 application that has been in production for over a year. Our last release was a couple of months ago. We use CSS for styling and application of background images to divs and such. The server is Windows 2003 with IIS. Suddenly, this week, we have had reports from some users that the page seems to hang up while loading. The status bar was showing the name of a background image used in the page main area (assigned in CSS). At our office, some of us could recreate the problem, while others could not. IE6 and Firefox do not seem to be affected, only IE7/8. Running Fiddler on an affected machine and trying to see what was happening with the requests seemed to make the problem go away (while running through Fiddler, it returned when not). Hitting Refresh on a hung load often made the page load just fine. I checked the background image, and even replaced it with an archived copy. No joy. We re-deployed the app from our production source. No Joy. We restarted IIS and eventually rebooted the whole server. There are no unusual entries in the event logs, the app logs or the IIS logs. Finally, I removed the image entirely and re-styled the page not to use a background image. That solved the problem at least for now. However, we have reports of other images "hanging." The images are PNGs, but I have heard some rumors that sometimes a GIF hangs, but I have no screenshot to confirm. This just started happening "out of the blue." There have been no releases or updates applied to the server recently. We even checked updates on clients to see if a recent Windows Update might have caused this on the client, but there was nothing updated within the last couple of weeks. If you have any information about this problem, I would love to hear from you. I would also greatly appreciate any recommendations on additional diagnostics we can try.

  • HTML 5 Video Error Media Src Not Supported

    - by Nirmal
    So I was working on a toy website (http://nirmalpatel.com/yeah/index.html). If you check the source, you can see that I have linked a m4v and ogg version. When I load this page from my own computer using a url that starts with file:// the page works fine in Safari, Chrome and Firefox. However, after I upload all of the videos and the HTML to my server Firefox stops working. I don't think it's a permissions issue as both videos have the same permission.

  • How to create picture slideshows in a rails project? Flash or otherwise

    - by Janak
    In a rails project how would I create a picture slideshow? It could be generated as flash or use prototype or something else. I just want a series of images (as a sub-part of a web page, not be the whole page) to fade into each other, and to advance manually if clicked. It would be nice if I could do things like slowly zoom into the images I imagine there must be a plugin or something to handle this?

    Given is a form that is followed by a confirmation page where you have to confirm you entered data of previous form. Now if the user refreshes this recapitulation page, the data form the previous form reposts. Is there a way to prevent that in JavaScript? I know its not a ideal solution, it should happen on the server side. But i have no choice in this case.
