  • 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?

  • Phonegap (Cordova) iOS button click

    - by JNM
    I am trying to create a very simple phone gap application for iOS. I am using query mobile. the problem is, that i can't get javascript event to fire on button click. Code i have now: <!DOCTYPE html> <html> <head> <title>Title</title> <meta name="viewport" content="width=device-width, minimum-scale=1, maximum-scale=1"> <meta charset="utf-8"> <link rel="stylesheet" type="text/css" href="js/jquery.mobile-1.2.0.css" /> <script type="text/javascript" charset="utf-8" src="cordova-1.8.1.js"></script> <script type="text/javascript" charset="utf-8" src="js/jquery-1.8.2.min.js"></script> <script type="text/javascript" charset="utf-8" src="js/jquery.mobile-1.2.0.min.js"></script> <script type="text/javascript"> document.addEventListener("deviceready", onDeviceReady, false); function onDeviceReady() { } function showAlert() { navigator.notification.alert("Cordova is working"); } </script> </head> <body> <div data-role="page" id="options" data-add-back-btn="true" data-back-btn-text="Atgal"> <div data-role="header" data-position="fixed"> <h1>Title</h1> </div> <div data-role="content"> <h1>Alert</h1> <p><a href="#" onclick="showAlert(); return false;" data-role="button">Show alert</a></p> </div> </div> </body> </html> I tried multiple solutions to fix my problem, but none of them works. When have button with # in href, it doesn't event change the color on click. When i add url, it changes color. But it never call javascript function. Another problem is, that document.addEventListener("deviceready", onDeviceReady, false); works only in the index page. If i press button in initial page which redirects to another page, OnDeviceReady function is never called. Anybody has any ideas?

  • 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?

  • Object relationships

    - by Hammerstein
    This stems from a recent couple of posts I've made on events and memory management in general. I'm making a new question as I don't think the software I'm using has anything to do with the overall problem and I'm trying to understand a little more about how to properly manage things. This is ASP.NET. I've been trying to understand the needs for Dispose/Finalize over the past few days and believe that I've got to a stage where I'm pretty happy with when I should/shouldn't implement the Dispose/Finalize. 'If I have members that implement IDisposable, put explicit calls to their dispose in my dispose method' seems to be my understanding. So, now I'm thinking maybe my understanding of object lifetimes and what holds on to what is just wrong! Rather than come up with some sample code that I think will illustrate my point, I'm going to describe as best I can actual code and see if someone can talk me through it. So, I have a repository class, in it I have a DataContext that I create when the repository is created. I implement IDisposable, and when my calling object is done, I call Dispose on my repository and explicitly call DataContext.Dispose( ). Now, one of the methods of this class creates and returns a list of objects that's handed back to my front end. Front End - Controller - Repository - Controller - Front End. (Using Redgate Memory Profiler, I take a snapshot of my software when the page is first loaded). My front end creates a controller object on page load and then makes a request to the repository sending back a list of items. When the page is finished loading, I call Dispose on the controller which in turn calls dispose on the context. In my mind, that should mean that my connection is closed and that I have no instances of my controller class. If I then refresh the page, it jumps to two 'Live' instances of the controller class. If I look at the object retention graph, the objects I created in my call to the list are being held onto ultimately by what looks like Linq. The controller/repository aside, if I create a list of objects somewhere, or I create an object and return it somewhere, am I safe to just assume that .NET will eventually come and clean things up for me or is there a best practice? The 'Live' instances suggest to me that these are still in memory and active objects, the fact that RMP apparently forces GC doesn't mean anything?

  • 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)

  • Unusual RJS error

    Hi, I am getting the following error in my RoR application: RJS error: TypeError: element is null Element.update("notice", "Comment Posted"); Element.update("allcomments", "\n\n\n \n\n waht now?\n\n \n\n \n\n \n\n asdfasdfa\n \n\n \n\n asdfasdf\n \n\n\n\n\n"); But when I hit the refresh button, I can see my partial updated.

  • 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.

  • How do I keep my app from tracking bot requests as views

    - by trustfundbaby
    This is a general question about writing web apps. I have an application that counts page views of articles as well as a url shortner script that I've installed for a client of mine. The problem is that, whenever bots hit the site, they tend to inflate the page views. Does anyone have an idea on how to go about eliminating bot views from the view count of these applications?

  • CTRL+mouse wheel in gvim (windows) not paging

    - by andrew
    Hello, I'm loving vim, but one thing that's bugging me is that when I hold the control key and mouse wheel up or down, the window scrolls normally when the bindings are telling it to page up/down. I'm using the exact same vimrc file (and plugins) on one of my linux machines and the CTRL+mouse wheel does page up down (as opposed to just normally scrolling like in windows). Is there some way to force gvim to response to a ctrl+MouseUp/Down event? It seems to be ignoring it in windows ='[

  • 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.

  • Sinatra Routing Exceptions

    - by Ethan Turkeltaub
    I want to be able to do the following: get '/:slug' do haml :page end get '/administration' do haml :admin end Is there a way that I can have get '/:slug' do have an exception for /administration? I realize you can do this with if else statements: get '/:slug' do if params[:slug] == 'administration' haml :admin else haml :page end end But that isn't very clean looking. Is there a way to have an exception to routes?

  • jquery tabs question

    - by badnaam
    The problem is every time a tab is activated, the cursor jumps to the top of the page, since the tab link points to a div and the page scrolls up to the top of the div. This creates a jumpy effect if the user has scrolled down a bit, while reading tab content. Is there anyway to prevent this?

  • ASP.NET button_click not firing, after browser back button

    - by the berserker
    I have a ASPX Page that contains several user controls, which are loaded dynamically after user interaction. On one of ascx I have a hidden button that is being clicked on some user actions (via button.click()), which works fine on 1st page load. But after the form is being submitted once, the other ascx is loaded. There if user clicks the back button and resubmits the 1st form (again via button.click()), button_clicked event on server does not fire again. Any thought?
