  • Django: Is it possible to attach media files (css, javascript etc) to a View-class?

    - by mrmclovin
    I can't fins any information on how to define css or javascript files in a view like: class MyView(View): .... class Media: css = { 'all' : 'mystyle.css' } If you have a form you can do like: class MyForm(ModelForm): .... class Media: css = { 'all' : 'mystyle.css' } And then in the template you can print the files like; {{ form.media.css }} I like that Syntax very much and I like to keep the View-specific css files in the app-directory. Does anyone know if it's possible? Thanks!

  • javascript "window.history.forward(1);" not working.

    - by Ray L.
    Hi, I'm trying to prevent the back button from working on one of my asp.net mvc pages. I've read a couple of places that if i put "window.history.forward(1);" in my page it will prevent the back button from working on a given page. This is what I did in my page: <script type="text/javascript"> $(document).ready(function () { window.history.forward(1); }); </script> It doesn't seem to be working. Am I using this incorrectly or is this approach wrong? thanks.

  • [.NET][C#] - Is possible to get a web with its links (CSS,JavaScript,Images, CSS-Images) ?

    - by Efrain
    Hi there, I am implementing a CMS, the case is that the "Web-Editable" is in a different domain thus, I would be able just get the page using HttpRequest in order to copy and show it in the CMS server to make it able to change it (DOM just visual purpose) and save the changes to the CSS and JavaScript folder on the "Web-Editable" using FTP. I am not allow to download all the information included on the "Web-Editable" trough the FTP, and there are other dinamic images as well comming from a private database. The question is, anyone knows how to make a httprequest "cascade" to get all the 1st level information you see when you visit a Web? Thank you in advance, Efrain

  • Massive number of context switches on ksoftirqd

    - by Pace
    We have two servers that are grinding to a halt. One is a VM and the other is bare metal. Neither of them are running similar code but they are on the same network. It appears that an incredible number of context switches are arising from ksoftirqd (which is taking up a lot of CPU). vmstat output procs -----------memory---------- ---swap-- -----io---- -system-- -----cpu------ r b swpd free buff cache si so bi bo in cs us sy id wa st 1 0 0 605092 182496 2637556 0 0 0 0 4177 519187 8 19 73 0 0 2 0 0 605092 182496 2637556 0 0 0 0 4792 520980 8 19 74 0 0 3 0 0 605092 182496 2637552 0 0 0 0 2137 659640 18 26 56 0 0 ... pidstat output TCK4-BM-06A:~ # pidstat -w -I 5 Linux 2.6.32.12-0.7-default (TCK4-BM-06A) 07/02/2012 _x86_64_ 03:03:01 PM PID cswch/s nvcswch/s Command 03:03:06 PM 1 0.20 0.00 init 03:03:06 PM 4 386666.27 0.00 ksoftirqd/0 03:03:06 PM 6 0.60 0.00 ksoftirqd/1 03:03:06 PM 8 378213.17 0.00 ksoftirqd/2 03:03:06 PM 10 0.20 0.00 ksoftirqd/3 03:03:06 PM 12 0.20 0.00 ksoftirqd/4 03:03:06 PM 26 377115.37 0.00 ksoftirqd/11 03:03:06 PM 27 1.80 0.00 events/0 03:03:06 PM 28 1.00 0.00 events/1 03:03:06 PM 29 1.00 0.00 events/2 03:03:06 PM 30 1.00 0.00 events/3 03:03:06 PM 31 0.80 0.00 events/4 03:03:06 PM 32 0.80 0.00 events/5 ...

  • How do you update table row background color in IE using Javascript/CSS ?

    - by giulio
    I have a table that i want to "highlight" during onmouseover/onmouseout. I already know this is required in IE but not in other browsers. I have managed to detect the events triggering and this TR tag effectively works. (Note that the originating class "contentTableRow" doesn't seem to be causing any issues.) class="contentTableRow" onclick="openForm('SomeID');" onmouseover="highlight('someRowID', true);" onmouseout="highlight('someRowID', false);" id="someRowID" All is fine and dandy, the "highlight" function fires and actually sets the appropriate class. It's just that IE won't process the CSS class name change. Here is a snippet of the CSS I am using to make the change. .HighlightOn { cursor:pointer; background-color: #D1DFFF; } .HighlightOff { background-color: #E1EEFE; } I can see that the Class names are getting updated when I debug it, and also check it in Firebug. But it seems that IE doesn't like this usage of classes with a TR tag.. Is it the way I am structuring the class for Tables ? Any advice ?

    Hi, I'd like to know how to put multiple markers for Google Maps using Javascript API v3. I tried the solution posted here: http://stackoverflow.com/questions/1621991/multiple-markers-in-googe-maps-api-v3-that-link-to-different-pages-when-clicked but it does not work for me for some reason. var directionDisplay; function initialize() { var myOptions = { zoom: 9, center: new google.maps.LatLng(40.81940575,-73.95647955), mapTypeId: google.maps.MapTypeId.TERRAIN } var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); setMarkers(map, properties); var properties = [ ['106 Ft Washington Avenue',40.8388485,-73.9436015,'Mjg4'], ]; function setMarkers(map, buildings) { var image = new google.maps.MarkerImage('map_marker.png', new google.maps.Size(19,32), new google.maps.Point(0,0), new google.maps.Point(10,32)); var shadow = new google.maps.MarkerImage('map_marker_shadow.png', new google.maps.Size(28,32), new google.maps.Point(0,0), new google.maps.Point(10,32)); var bounds = new google.maps.LatLngBounds; for (var i in buildings) { var myLatLng = new google.maps.LatLng(buildings[i][1], buildings[i][2]); bounds.extend(myLatLng); var marker = new google.maps.Marker({ position: myLatLng, map: map, shadow: shadow, icon: image, title: buildings[i][0] }); google.maps.event.addListener(marker, 'click', function() { window.location = ('detail?b=' + buildings[i][3]); }); } map.fitBounds(bounds); } } </script> Could anyone kindly explain why this doesn't work for me?

  • JQuery tools.scrollable conflict with navbar Ajax in CakePHP

    - by user269098
    In our views/layout/default.ctp file we have an element that's used to implement a cascading combo select box which uses JQuery ajax to update the fields. This selector is part of our navbar and is loaded on every page of the site. The default.ctp has these includes in the : <?php echo $html->charset(); ?> <title><?php echo $title_for_layout; //if(Configure::read('debug')) //echo "cake: " . Configure::version(); ?></title> <?php echo $html->css('style'); echo $javascript->link('jquery', true); echo $javascript->link('jquery.form', true); echo $javascript->link('jquery.url', true); echo $javascript->link('navbar', true); echo $html->script('tools.expose-1.0.3.js', array('inline' => false)); //echo $scripts_for_layout; ?> On the views/cars/index.ctp page we have: echo $javascript->link('tools.tabs-1.0.1', true); echo $javascript->link('tools.overlay-1.0.4', true); echo $javascript->link('jquery.form', true); echo $javascript->link('tools.scrollable-1.0.5', true); The issue is that on every other page the navbar combo box selector works. However, on the cars/index.ctp it doesn't work. It only works when we comment out the 'tools.scrollable' include. Any ideas why there is this conflict? We have been stuck on this problem for months...

  • JSF Page does not submit when onclick javascript is added to menu item?

    - by Padmarag
    I show some detail using popup windows. I want to close those when the user clicks on sign-out link. I have a JavaScript function that'll close the windows. The sign-out link is rendered using Navigation MenuModel. The definition in faces-config is as below - <managed-bean> <managed-bean-name>signoutNavigation</managed-bean-name> <managed-bean-class>com.xxx.xxx.framework.NavigationItem</managed-bean-class> <managed-bean-scope>none</managed-bean-scope> <managed-property> <property-name>label</property-name> <value>Sign Out</value> </managed-property> <managed-property> <property-name>viewId</property-name> <value>/signout.jsp</value> </managed-property> <managed-property> <property-name>outcome</property-name> <value>signout</value> </managed-property> <managed-property> <property-name>onclick</property-name> <value>closeOrderWindows()</value> </managed-property> </managed-bean> The problem is when I use the "onclick" property on managed-bean, the page doesn't submit to "signout.jsp" and remains on same page. When I remove/comment the "onclick" part, the page gets submitted properly. I use MyFaces Trinidad.

  • Javascript help fixing a working time ago date function to simply show seconds ago.

    - by Scarface
    Hey guys quick question, I am using a javascript function and it works except I can only make it say 0 seconds ago, when the time is under a minute. Can anyone quickly explain what I am doing wrong? function handleDate( timestamp ) { var n=new Date(), t, ago = " "; if( timestamp ) { t = Math.round( (n.getTime()/1000 - timestamp)/60 ); ago += handleSinceDateEndings( t, timestamp ); } else { ago += ""; } return ago; } function handleSinceDateEndings( t, original_timestamp ) { var ago = " ", date; if( t <= 1 ) { ago += t + " seconds ago"; } else if( t<60) { ago += t + " mins ago"; } else if( t>= 60 && t<= 120) { ago += Math.floor( t / 60 ) + " hour ago" } else if( t<1440 ) { //console.log(t) ago += Math.floor( t / 60 ) + " hours ago"; } else if( t< 2880) { ago += "1 day ago"; } else if( t > 2880 && t < 4320 ) { ago += "2 days ago"; } else { date = new Date( parseInt( original_timestamp )*1000 ) ago += months[ date.getMonth() ] + " " + date.getDate(); } return ago; } var months = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];

  • How do I scrape information off ASP.NET websites when paging and JavaScript links are being used?

    - by Ian Roke
    I have been given a staff list which is supposed to be up to date but it doesn't match an intranet People Finder which is written in ASP.NET. As the information is sensitive I am not able to access the database the People Finder is using so the only way I can get at the information is by scraping the structure starting at the top brass at the top and then going through each tier in turn. Each person has a Staff number which then forms the URL http://intranet/peoplefinder/index.aspx?srn=ABC1234 and then all the people who report to them are listed underneth in the format <a id="gvEmployees_ctl03_lnkFullName" href="index.aspx?srn=ABC4321" target="_self"> where each URL indicates the Staff number and provides a link to their team. The trouble arises when the teams are big as paging is implemented in the GridView with an URL such as <a href="javascript:__doPostBack('gvEmployees','Page$2')">2</a>. How would I scrape this page, capture the SRN and other details along with the people who report to the person on all pages of the GridView then loop through each reportee and do the same process until the whole list is complete?

  • How to more effectively debug PHP code in the vein JavaScript with Firebug or XCode?

    - by racl101
    Hi everyone, I'm kind of a newbie with PHP so please bear with me. I would like to know if there was an effective way of debugging PHP code so that I don't have to have debugging messages display on the browser. For example, I find var_dump and print_r functions to be excellent for debugging variables, function calls and arrays respectively. The problem is I have been asked to debug code on a live site (no dev site, I know it is a horrible practice but this is not my project from the start.) So I would like to know what core function or php library or whatever else it is that I could use to log debugging calls in to log that I can check so I don't have to send debugging calls to the browser on a live site? I like the way you can use the console.log function in JavaScript code and check it in Firebug or the Webkit Console and I also like like the console window in Xcode and I was wondering if there was some similar tool for PHP debugging. Any extra info and pearls of wisdom would be greatly appreciated. Thanks, racl101.

  • Adding Css class to all <input type'text'> elements? Javascript / Css?

    - by Kohan
    I want to apply a CSS class to every textbox in my site: <div class="editor-label"> <label for="FoodType">FoodType</label> </div> <div class="editor-field"> <input id="HelpText" name="FoodType" type="text" value="" /> </div> <p> <input type="submit" value="Create" /> </p> And I thought, Hey! Easy. I'll add a jquery function to find them all in the masterpage. <script type="text/javascript"> $(document).ready(function(){ $('input').addClass('textbox'); } </script> Unfortunately this will also select the submit button. How can i only select input elements that have a text type attribute? Alternativly is this possible using entirely CSS? If both these methods are not possible, i guess i will just have to manually add the class to every textbox i make? Cheers, Kohan.

  • How can a link within a WebView load another layout using javascript?

    - by huffmaster
    So I have 2 layout files (main.xml, featured.xml) and both each have a single WebView. When the application starts "main.xml" loads a html file into it's WebView. In this html file I have a link that calls javascript that runs code in the Activity that loaded the html. Once back in this Activity code though I try running setContentView(R.layout.featured) but it just bombs out on me. If I debug it just dies without any real error and if I run it the application just Force closes. Am I going about this correctly or should I be doing something differently? final private int MAIN = 1; final private int FEATURED = 2; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); webview = (WebView) findViewById(R.id.wvMain); webview.getSettings().setJavaScriptEnabled(true); webview.getSettings().setSupportZoom(false); webview.addJavascriptInterface(new EHJavaScriptInterface(), "eh"); webview.loadUrl("file:///android_asset/default.html"); } final class EHJavaScriptInterface { EHJavaScriptInterface() { } public void loadLayout(final String lo) { int i = Integer.parseInt(lo.trim()); switch (i) { /****** THIS IS WHERE I'M BOMBING OUT *********/ case FEATURED: setContentView(R.layout.featured);break; case MAIN: setContentView(R.layout.main);break; } } }

  • Two Phase Commit with MongoDB

    Heres what Im thinking. Do you see any issues with this workaround to emulate 2 phase commit when using something like MongoDB where each operation is atomic and there is no support for transactions outside of that? transaction_scope: read message from servicebus - UpdateCustomerAddress get customer aggregate from docdb, replay events where commited =1 call customer.updateAddress validates creates customer address updated event apply event event store as uncommitted events do optimistic concurrency update against docdb pushing uncommitted events (single op to ensure consistency) publish event to service bus update docdb set events just published to commited = 1 (again one 1 op - at least in mongodb) transaction_complete

  • How should a process running outside Internet Explorer talk to JavaScript running inside it?

    - by Paul Crowley
    This may well be impossible; either way I'm sure people here will know. I'm trying to reduce three "OK" prompts to two. As part of my application, users will download and run an executable I supply; call it privileged.exe. privileged.exe will have a coda that asks for the highest privileges available. That's two OK prompts, one to run privileged.exe and one for UAC. I'd like privileged.exe to then install an ActiveX control, browser plugin or some such. The purpose of this ActiveX control is to allow the JavaScript running inside the browser to talk to the running privileged.exe process, to allow the user to perform certain operations that require high privileges by making choices in the browser. And I'd ideally like this to happen without the user having to restart their browser or explicitly OK the installation of the ActiveX control. Is that possible? Can you install an ActiveX control from outside the browser in such a way that it becomes immediately available to pages running inside the browser? Or should I give up, and allow the user to be explicitly prompted to install the ActiveX control?

  • populate CoreData data model from JSON files prior to app start

    - by johannes_d
    I am creating an iPad App that displays data I got from an API in JSON format. My Core Data model has several entities(Countries, Events, Talks, ...). For each entity I have one .json file that contains all instances of the entity and its attributes as well as its relationships. I would like to populate my Core Data data model with these entities before the start of the App (otherwise it takes about 15 minutes for the iPad to create all the instances of the entities from the several JSON files using factory methods). I am currently importing the data into CoreData like this: -(void)fetchDataIntoDocument:(UIManagedDocument *)document { dispatch_queue_t dataQ = dispatch_queue_create("Data import", NULL); dispatch_async(dataQ, ^{ //Fetching data from application bundle NSURL *tedxgroupsurl = [[NSBundle mainBundle] URLForResource:@"contries" withExtension:@"json"]; NSURL *tedxeventsurl = [[NSBundle mainBundle] URLForResource:@"events" withExtension:@"json"]; //converting the JSON files to NSDictionaries NSError *error = nil; NSDictionary *countries = [NSJSONSerialization JSONObjectWithData:[NSData dataWithContentsOfURL:countriesurl] options:kNilOptions error:&error]; countries = [countries objectForKey:@"countries"]; NSDictionary *events = [NSJSONSerialization JSONObjectWithData:[NSData dataWithContentsOfURL:eventsurl] options:kNilOptions error:&error]; events = [events objectForKey:@"events"]; //creating entities using factory methods in NSManagedObject Subclasses (Country / Event) [document.managedObjectContext performBlock:^{ NSLog(@"creating countries"); for (NSDictionary *country in countries) { [Country countryWithCountryInfo:country inManagedObjectContext:document.managedObjectContext]; //creating Country entities } NSLog(@"creating events"); for (NSDictionary *event in events) { [Event eventWithEventInfo:event inManagedObjectContext:document.managedObjectContext]; // creating Event entities } NSLog(@"done creating, saving document"); [document saveToURL:document.fileURL forSaveOperation:UIDocumentSaveForOverwriting completionHandler:NULL]; }]; }); dispatch_release(dataQ); } This combines the different JSON files into one UIManagedDocument which i can then perform fetchRequests on to populate tableViews, mapView, etc. I'm looking for a way to create this document outside my application & add it to the mainBundle. Then I could copy it once to the apps DocumentsDirectory and be able I use it (instead of creating the Document within the app from the original JSON files). Any help is appreciated!

  • SIFR, JAVASCRIPT & PHP - How to apply SIFR to dynamically loaded content.

    - by user311039
    Well here's the problem: I have a PHP index page which uses show/hide layers javascript. I am using the on menu.click function to show and hide content relevant to each menu. On.click all divs are hidden except the content for that menu item , which fades in. The content relating to each menu item are displayed within separate DIVS. The property is applied to all the text within all the divs. See: http://jobe-group.com/jobeco/uk/2010live/dynamic/content/index.php# The trouble is that SIFR only appears to be applied to the displayed on.load when the page is first loaded. When this is hidden and the other s shown through the "show" function they load in classic CSS fonts without the SIFR applied. Is this unavoidable with the SIFR setup. Or am I not calling the divs properly. I have set the SIFR to apply to the selector and indeed it works fine on the for the displayed on load. It doesn't work for the within other . In theory I would think its possible to load the SIFR on all divs on page.load even if those divs are presently visibility:hidden. What's the verdict on this? Hope someone can help. Cheers, John

  • Multiset container appears to stop sorting

    - by Sarah
    I would appreciate help debugging some strange behavior by a multiset container. Occasionally, the container appears to stop sorting. This is an infrequent error, apparent in only some simulations after a long time, and I'm short on ideas. (I'm an amateur programmer--suggestions of all kinds are welcome.) My container is a std::multiset that holds Event structs: typedef std::multiset< Event, std::less< Event > > EventPQ; with the Event structs sorted by their double time members: struct Event { public: explicit Event(double t) : time(t), eventID(), hostID(), s() {} Event(double t, int eid, int hid, int stype) : time(t), eventID( eid ), hostID( hid ), s(stype) {} bool operator < ( const Event & rhs ) const { return ( time < rhs.time ); } double time; ... }; The program iterates through periods of adding events with unordered times to EventPQ currentEvents and then pulling off events in order. Rarely, after some events have been added (with perfectly 'legal' times), events start getting executed out of order. What could make the events ever not get ordered properly? (Or what could mess up the iterator?) I have checked that all the added event times are legitimate (i.e., all exceed the current simulation time), and I have also confirmed that the error does not occur because two events happen to get scheduled for the same time. I'd love suggestions on how to work through this. The code for executing and adding events is below for the curious: double t = 0.0; double nextTimeStep = t + EPID_DELTA_T; EventPQ::iterator eventIter = currentEvents.begin(); while ( t < EPID_SIM_LENGTH ) { // Add some events to currentEvents while ( ( *eventIter ).time < nextTimeStep ) { Event thisEvent = *eventIter; t = thisEvent.time; executeEvent( thisEvent ); eventCtr++; currentEvents.erase( eventIter ); eventIter = currentEvents.begin(); } t = nextTimeStep; nextTimeStep += EPID_DELTA_T; } void Simulation::addEvent( double et, int eid, int hid, int s ) { assert( currentEvents.find( Event(et) ) == currentEvents.end() ); Event thisEvent( et, eid, hid, s ); currentEvents.insert( thisEvent ); }

  • What are the javascript performance tradeoffs in adding id's to dom elements?

    - by Blinky
    For example, I have a website which has a dynamically-generated segment of its dom which looks roughly like this: <div id="master"> <div class="child"> ... </div> <div class="child"> ... </div> <div class="child"> ... </div> ... <div class="child"> ... </div> </div> There might be hundreds of child elements in this manner, and they, too, might have yet more children. At present, none of them have id's except for the master. Javascript manipulates them via dom-walking. It's a little scary. I'd like to add id's, e.g.: <div id="master"> <div id="child1" class="child"> ... </div> <div id="child2" class="child"> ... </div> <div id="child3" class="child"> ... </div> ... <div id="childN" class="child"> ... </div> </div> What are the tradeoffs in adding id's to these divs? Certainly, jQuery must maintain a hash of id's, so there's going to be some sort of performance hit. Any general guidelines in when adding additional id's is a bad idea? Is jQuery so awesome that, in practice, it doesn't matter?

  • How do I force MyEclipse to hot-deploy a JavaScript file to my JBoss instance?

    - by Mike Cialowicz
    I'm having trouble with MyEclipse 7.1.1 hot-deployment of files to my JBoss 4 server. The problem is this: while my server is running, I can make changes to various JAVA and HTML files, which are then hot-deployed immediately (I can see the changes reflected in my browser when I refresh the page). However, while working on a particular JavaScript file, my changes are not being hot-deployed. This makes it very difficult to work on and debug this file, since I have to stop my server, redeploy, and start it again each time I make changes. This is a new problem - it didn't used to happen with this file, so I think something got screwed up in my MyEclipse configuration. I've verified that my projects (JBoss 4 instances) are all set up in "Exploded" mode for hot-deployment. I'm also 99% sure that this isn't an issue with my browser, since I always refresh with CTRL+F5, and I've tried a number of things like clearing my browser cache to get the currently deployed version of the file. I've also tried doing a "clean" on the project while the server is running, and that didn't force a deployment either. Any sort of solution would be helpful. I'd love for MyEclipse to deploy the file automatically, but I'm also open to manually forcing hot-deployment of this particular file while I work on it. Thank you.
