  • Getting the highlighted text inside selected element only.

    - by ashays
    My goal is to be able to get the highlighted text within a document, but only if that text is within a given section, and then apply a certain style to that selected text after clicking a div tag. I'll explain what I mean: So, having looked at window.getSelection() and document.selection.createRange().text, I attempted to use elmnt.getSelection() or elmnt.selection.createRange().text for some HTML element, elmnt. However, it doesn't seem to work, so that idea seems pretty null. This means I can't use this idea to determine the text that is highlighted within a given location. In case this doesn't make sense, essentially, I want html code that looks like this: <body> <div id="content">Stuff here will not be effected</div> <div id="highlightable">Stuff here can be effected when highlighted</div> <div id="morecontent">Stuff here will also not be effected</div> </body> So that whenever I've highlighted text, clicking on a specified div will apply the proper CSS. Now, on to the div tags. Basically, here's what I've got on that: $('.colorpicker').click( function(e) { console.log(getSelectedText()); } Eventually, all I want this to highlight the selected text and have the div tag change the color of the selected text to that of the respective div tag that I've selected. Neither of these seems to be working right now, and my only guess for the reason of the div tag is that it unhighlights whatever I've got selected whenever I click on the div tag. Fallbacks: If there is more than one time that 'abc' is found on the page and I highlight to color 'abc', I would like that only that copy of 'abc' be highlighted. I know this is a lot in one question, but even if I could get a little head start on this idea, my next personal project would be going a lot more smoothly. Thanks. :)

  • Authentication using cookie key with asynchronous callback

    - by greg
    I need to write authentication function with asynchronous callback from remote Auth API. Simple authentication with login is working well, but authorization with cookie key, does not work. It should checks if in cookies present key "lp_login", fetch API url like async and execute on_response function. The code almost works, but I see two problems. First, in on_response function I need to setup secure cookie for authorized user on every page. In code user_id returns correct ID, but line: self.set_secure_cookie("user", user_id) does't work. Why it can be? And second problem. During async fetch API url, user's page has loaded before on_response setup cookie with key "user" and the page will has an unauthorized section with link to login or sign on. It will be confusing for users. To solve it, I can stop loading page for user who trying to load first page of site. Is it possible to do and how? Maybe the problem has more correct way to solve it? class BaseHandler(tornado.web.RequestHandler): @tornado.web.asynchronous def get_current_user(self): user_id = self.get_secure_cookie("user") user_cookie = self.get_cookie("lp_login") if user_id: self.set_secure_cookie("user", user_id) return Author.objects.get(id=int(user_id)) elif user_cookie: url = urlparse("http://%s" % self.request.host) domain = url.netloc.split(":")[0] try: username, hashed_password = urllib.unquote(user_cookie).rsplit(',',1) except ValueError: # check against malicious clients return None else: url = "http://%s%s%s/%s/" % (domain, "/api/user/username/", username, hashed_password) http = tornado.httpclient.AsyncHTTPClient() http.fetch(url, callback=self.async_callback(self.on_response)) else: return None def on_response(self, response): answer = tornado.escape.json_decode(response.body) username = answer['username'] if answer["has_valid_credentials"]: author = Author.objects.get(email=answer["email"]) user_id = str(author.id) print user_id # It returns needed id self.set_secure_cookie("user", user_id) # but session can's setup

  • Handle order dependence in for loops

    - by Matt
    Hey all, I'm making a templating system where I instantiate each tag using a foreach loop. The issue is that some of the tags rely on each other so, I'm wondering how to get around that ordering from the looping. Here's an example: Class A { public $width; __construct() { $this->width = $B->width(); // Undefined! Or atleast not set yet.. } } Class B { private $width; __construct() { $this->width = "500px"; } __tostring() { return "Hello World!"; } } Template.php $tags = array("A", "B"); foreach ($tags as $tag) { $TagObj[$tag] = new $tag(); } echo $TagObj['A']->width; // Nadamundo! I know this has applications elsewhere and I'm sure this has been solved before, if someone could enlighten me or point me in the right direction that'd be great! Thanks! Matt Mueler

  • iPhone, JQTouch and HTML5 audio tags

    - by Moo
    I am having an issue with JQTouch (latest beta) and html5 audio tags on 'sub pages' - the audio tag works before any page transitions are done, and cease to work afterward. For example: http://richardprice.dyndns.ws/test.html and http://richardprice.dyndns.ws/test2.html are identical other than I swap the "current" class between the two divs - all the audio tags play the same mp3. On test.html the audio tag on the initial page works, but when you switch to Page 2 the audio tag on that page does not (and sometimes results in a browser crash). Switch back to Page 1 and the audio tag on that page has ceased to work. test2.html is the same test but with the initial pages reversed, and the same thing happens - Page 2 (now the initial page) plays the audio, Page 1 does not, and switching back to Page 2 results in the audio no longer working. Thoughts?

  • Repository organization and selective checkout

    - by Maurizio Reginelli
    I am using TortoiseSVN and I have a SVN repository organized in this way: folder1 folder2 trunk tag branches folder3 trunk tag branches folder4 folder5 trunk tag branches I would like to know if there is a way to checkout only trunk directories, keeping the entire tree under the versioning control: folder1 folder2 trunk folder3 trunk folder4 folder5 trunk In this way I can update all trunks with a single update command on folder1, without updating tags and branches which can be full of data.

  • Groupby in relationtable

    - by Dofs
    I am creating some tag functionality for a forum using linq2sql, and I have two tables [Tag] TagId TagName [ForumTagRelation] TagId ForumId I would like to retrieve, like SO, the most popular tags. I have tried to do this by: List<Tag> popularTags = db.Tags.Select(x => x.ForumTagRelations.GroupBy(y => y.TagId).OrderByDescending(z => z.Count())).Take(count).ToList(); But this just returns the following error: Error 1 Cannot implicitly convert type 'System.Collections.Generic.List<System.Linq.IOrderedEnumerable<System.Linq.IGrouping<System.Guid?,SampleWebsite.ForumTagRelation>>>' to 'System.Collections.Generic.IEnumerable<SampleWebsite.Tag>'. An explicit conversion exists (are you missing a cast?) The question is how I easily can return a list of tags which has the most counts in the ForumTagRelation table?

  • Using Scala and StringTemplate, how do I loop through a Map

    - by Marcus Kazmierczak
    I have my environment setup nicely using Scala, StringTempalte within the Google AppEngine. I am having trouble looping through a Map and getting it to display in the template. When I assign a simple List of just Strings to the template it works using: In Scala Servlet: var photos = List[String]() //... get photo url and title ... photos = photo_url :: photos template.setAttribute("photos", photos: _*) In Template: $photos: { photo| <div><img src="$photo$_s.jpg"></div> }$ The above works. However, any attempt of creating a Map using url and title and assigning to the template gives me an error. Here is my attempt, which does not work: In Scala Servlet: var photos = List[Map[String,String]]() //... get photo url and title ... photos = Map("url" -> url, "title" -> title) :: photos template.setAttribute("photos", photos: _*) In Template: $photos: { photo| <div><img src="$photo.url$_s.jpg" title="$photo.title$"></div> }$ This gives me the following error Class scala.collection.immutable.Map$Map2 has no such attribute: title in template context Thoughts / Ideas ?

  • paging helper asp.net mvc

    - by csetzkorn
    Hi, I have implemented a paging html helper (adapted from steven sanderson's book). This is the current code: public static string PageLinks(this HtmlHelper html, int currentPage, int totalPages, Func pageUrl) { StringBuilder result = new StringBuilder(); for (int i = 1; i <= totalPages; i++) { TagBuilder tag = new TagBuilder("a"); tag.MergeAttribute("href", pageUrl(i)); tag.InnerHtml = i.ToString(); if (i == currentPage) tag.AddCssClass("selectedPage"); result.AppendLine(tag.ToString()); } return result.ToString(); } This produces a bunch of links to each page of my items. If there are many pages this can be a bit overwhelming. I am looking for a similar implementation which produces something less overwhelming like this: where 6 is the current page. I am sure someone must have implemented something similar ... before I have to re-implement the wheel. Thanks. Christian

  • Parse JSON into a ListView friendly output

    - by Thomas McDonald
    So I have this JSON, which then my activity retrieves to a string: {"popular": {"authors_last_month": [ { "url":"http://activeden.net/user/OXYLUS", "item":"OXYLUS", "sales":"1148", "image":"http://s3.envato.com/files/15599.jpg" }, { "url":"http://activeden.net/user/digitalscience", "item":"digitalscience", "sales":"681", "image":"http://s3.envato.com/files/232005.jpg" } { ... } ], "items_last_week": [ { "cost":"4.00", "thumbnail":"http://s3.envato.com/files/227943.jpg", "url":"http://activeden.net/item/christmas-decoration-balls/75682", "sales":"43", "item":"Christmas Decoration Balls", "rating":"3", "id":"75682" }, { "cost":"30.00", "thumbnail":"http://s3.envato.com/files/226221.jpg", "url":"http://activeden.net/item/xml-flip-book-as3/63869", "sales":"27", "item":"XML Flip Book / AS3", "rating":"5", "id":"63869" }, { ... }], "items_last_three_months": [ { "cost":"5.00", "thumbnail":"http://s3.envato.com/files/195638.jpg", "url":"http://activeden.net/item/image-logo-shiner-effect/55085", "sales":"641", "item":"image logo shiner effect", "rating":"5", "id":"55085" }, { "cost":"15.00", "thumbnail":"http://s3.envato.com/files/180749.png", "url":"http://activeden.net/item/banner-rotator-with-auto-delay-time/22243", "sales":"533", "item":"BANNER ROTATOR with Auto Delay Time", "rating":"5", "id":"22243"}, { ... }] } } It can be accessed here as well, although it because it's quite a long string, I've trimmed the above down to display what is needed. Basically, I want to be able to access the items from "items_last_week" and create a list of them - originally my plan was to have the 'thumbnail' on the left with the 'item' next to it, but from playing around with the SDK today it appears too difficult or impossible to achieve this, so I would be more than happy with just having the 'item' data from 'items_last_week' in the list. Coming from php I'm struggling to use any of the JSON libraries which are available to Java, as it appears to be much more than a line of code which I will need to deserialize (I think that's the right word) the JSON, and they all appear to require some form of additional class, apart from the JSONArray/JSONObject script I have which doesn't like the fact that items_last_week is nested (again, I think that's the JSON terminology) and takes an awful long time to run on the Android emulator. So, in effect, I need a (preferably simple) way to pass the items_last_week data to a ListView. I understand I will need a custom adapter which I can probably get my head around but I cannot understand, no matter how much of the day I've just spent trying to figure it out, how to access certain parts of a JSON string..

  • PHP regex help -- reverse search?

    - by Ian Silber
    So, I have a regex that searches for HTML tags and modifies them slightly. It's working great, but I need to do something special with the last closing HTML tag I find. Not sure of the best way to do this. I'm thinking some sort of reverse reg ex, but haven't found a way to do that. Here's my code so far: $html = "<div id="test"><p style="hello_world">This is a test.</p></div>"; $pattern = array('/<([A-Z][A-Z0-9]*)(\b[^>]*)>/i'); $replace = array('<tag>'); $html = preg_replace($pattern,$replace,$html); // Outputs: <tag><tag>This is a test</p></div> I'd like to replace the last occurance of "" with something special, say for example, "". Any ideas?

  • How to Send Headers Through PHP Proxy?

    - by blabus
    Okay, so I have an issue with an AJAX request. I currently have this URL: http://www.google.com/images?hl=en&safe=off&gbv=2&tbs=isch%3A1&sa=1&q=cars+imagesize%3A500x500&aq=f&aqi=&aql=&oq=&gs_rfai=&start=0 I then pass it to my proxy script by modifying the string to this: proxy.php?url=http://www.google.com/images?hl=en&safe=off&gbv=2&tbs=isch%3A1&sa=1&q=cars+imagesize%3A500x500&aq=f&aqi=&aql=&oq=&gs_rfai=&start=0 I need to use the PHP proxy script to grab that page's HTML so that I can then parse through it with javascript. However, the problem is that the headers in that URL are also being sent to the proxy script, and as a result, I get a 'malformed or illegal request' error. I'm pretty sure the two different sets of headers are the problem, because if I just replace the original URL string with 'http://wwww.google.com', the proxy returns the HTML of the page correctly. So basically, I don't know how to fix this. I'm a complete PHP noob, and I tried escaping the original URL before I appended it to the 'proxy.php?url=', but that doesn't fix anything. Any ideas? Thanks!

  • How To Share Information Between Django and Javascript?

    - by Randy
    So I am pretty new to both Django and Javascript (I am using JQuery) and I am wondering if I am doing a hack or if there are more slick ways to send client-side displayed database ids to the django server-side. Here is my process: I have a dataTable (http://datatables.net) that I am displaying rows of data by using the bProcessing option to use AJAX to retrieve records from the database. The URL in my urls.py is something like: url(r'^assets/activitylog/(?P<cid>.*)$', views.getActivityTable_ajax, name="activitylog_table"), and my dataTable ajax-relavant code is something like: "sAjaxSource": "/assets/activitylog/" + getIDFromHTML(), where the javascript function getIDFromHTML() grabs <cid> that is used by the Django view is simply: function getIDFromHTML(){ // Simply return the text in the #release_id div element from the HTML return $("#release_id").html(); }; This is the part that seems "hacky" to me. I am inserting into my template code the database id that I am using in the datatables URL (with display:none in the css) just so I can pass it back to the view. Most of this is necessitated because one cannot use django template tags in the javascript code unless the code is embedded into the HTML itself, which I am not (and will not) do. The only other thing that I have found is to change the URL to get rid of the parameter passed in to: url(r'^assets/activitylog', views.getActivityTable_ajax, name="activitylog_table"), and change the view code to: def getActivityTable_ajax(request): """Returns the activity for a given pid from HTTP GET ajax reqest""" pid = int(urlparse.urlparse(request.META['HTTP_REFERER']).path.split('/')[-1]) # rest of view code here... since the id that I need is on the end of this referer url. This way I don't have to monkey around with embedding the hidden database id into the HTML and passing it back to via ajax the the table population view code. Is it okay to use HTTP_REFERER in the request object in this manner? Am I going about this in the totally wrong way? Thanks in advance!

  • jQuery AJAX chained calls + Celery in Django

    - by user1029968
    Currently clicking one of the links in my application, triggers AJAX call (GET) that - if succeeds - triggers the second one and this second one - if succeeds - calls the third one. This way user can be informed which part of process started when clicking the link is currently ongoing. So in the template file in Django project, click callback body for link mentioned looks like below: $("#the-link").click(function(item)) { // CALL 1 $.ajax({ url: {% url ajax_call_1 %}, data: { // something } }) .done(function(call1Result) { // CALL 2 $.ajax({ url: {% url ajax_call_1 %}, data: { // call1Result passed here to CALL 2 } }) .done(function(call2Result) { // CALL 3 $.ajax({ url: {%url ajax_call_3 %}, data: { // call2Result passed here to CALL 3 } }) .done(function(call3Result) { // expected result if everything went fine console.log("wow, it worked!"); console.log(call3Result); }) .fail(function(errorObject) { console.log("call3 failed"); console.log(errorObject); } }) .fail(function(errorObject)) { console.log("call2 failed"); console.log(errorObject); } }) .fail(function(errorObject) { console.log("call1 failed"); console.log(errorObject); }); }); This works fine for me. The thing is, I'd like to prevent interrupting the following calls if the user closes the browser and the calls are not finished (as it will take some time to finish all three), as there is some additional logic in Django view functions called in each GET request. For example, if user clicks the link and closes the browser during CALL 1, is it possible to somehow go on with the following CALL 2 and CALL 3? I know that normally I'd be able to use Celery Task to process the function but is it still possible here with the chained calls mentioned? Any help is much appreciated!

  • Enforcing a Uniqueness Constraint in a Nested Form

    - by Euwyn
    I'm trying not to fight the defaults here and use Rails built-in support for nested attributes (from http://ryandaigle.com/articles/2009/2/1/what-s-new-in-edge-rails-nested-attributes). I'm labeling Things with Tags, and all works swell, and for each Thing I have a form with a nested field that creates a new Tag by a name. Trouble is, I need to make sure that each Tag has a unique name. Instead of creating a new Tag, if a user enters the name of one that already exists, I need to create the associate with that pre-existing Tag. How do I do this?

  • How do you populate a UIImage view with ASIHTTPRequest given @2x?

    - by Jonathan Page
    I've been trying to load images from a url using ASIHTTPRequest but I always come up with a blank UIImage. I think it might have something to do with iOS automatically choosing the @2x named version of images or vica versa. [ASIHTTPRequest setDefaultCache:[ASIDownloadCache sharedCache]]; NSString *url_string = [NSString stringWithFormat:@"http://173.246.100.185/%@", [eventDictionary objectForKey:kEventDescriptionImageURLKey]]; NSURL *url = [NSURL URLWithString:url_string]; __block ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url]; [request setDownloadCache:[ASIDownloadCache sharedCache]]; [request setCachePolicy:ASIAskServerIfModifiedCachePolicy|ASIFallbackToCacheIfLoadFailsCachePolicy]; [request setCacheStoragePolicy:ASICachePermanentlyCacheStoragePolicy]; [request setSecondsToCache:86400]; [request setDelegate:self]; [request setCompletionBlock:^{ NSLog(@"Successful Update"); [self makeAssignment]; }]; [request setFailedBlock:^{ NSError *error = [request error]; NSLog(@"%@", [error localizedDescription]); UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Update Failed" message:[error localizedDescription] delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; [alert release]; }]; [request startAsynchronous]; NSLog(@"%@", url_string); The makeAssignment method is below. NSString *url_string = [NSString stringWithFormat:@"http://173.246.100.185/%@", [eventDictionary objectForKey:kEventDescriptionImageURLKey]]; NSURL *url = [NSURL URLWithString:url_string]; downloadedImage = [[UIImage alloc] initWithContentsOfFile:[[ASIDownloadCache sharedCache] pathToCachedResponseDataForURL:url]]; NSLog(@"%@", downloadedImage); NSLog(@"%@", [[ASIDownloadCache sharedCache] pathToCachedResponseDataForURL:url]); Nothing I do, including naming images @2x on the server or providing both versions, gets it to load. Any ideas? Has anyone done this before? When I load them locally (from within the package) I don't have any issues. Thanks!

  • Linq merging results

    - by glenneroo
    I'm working with a list within a list. This is how I'm currently searching: var tags = from fd in BigList from tag in fd.Tags where tag.Id == selectedTag.Id || tag.Id == ID.TIMESTAMP select new { fd.Name, tag.Id, tag.Value }; I then iterate over the result-set and remembering when Timestamp pops up for the next entry, needless to say this is sloppy and I'm positive there's a better way using Linq, I just can't seem to find the syntax. Here's some sample output (Id indicates what type of data is stored inside e.g. a timestamp): Name | Id | Value -----|----|---------- 0000 | 1 | <timestamp> 0000 | 2 | 1.2 ... 9999 | 1 | <timestamp> 9999 | 2 | 6.3 I need all instances where Id = selectedTag.Id. I just want 1 list with Name, Id, Value and Timestamp, but the problem is my above attempt returns 2 entries for every item (1 for timestamp and 1 for the value). Is there a way to do this using Linq? Preferably using query syntax! :)
