  • How do I get Google Chrome's root bookmarks folder?

    - by Wayne
    Hi, I'm trying to write a better bookmark manager in chrome extensions. The problem is there are no simple examples (that I can find) about how to actually use the bookmarks api (available here: http://code.google.com/chrome/extensions/bookmarks.html ) I've looked at the example source (when I d/led and installed it on my computer it didn't do anything except provide a search box. Typing/typing and pressing return failed to do anything) and can't find anything useful. My ultimate goal is to make an extension that allows me to save pages to come and read later without having to go sign up for an account on some service somewhere. So I plan to create either one or two bookmark folders in the root folder/other bookmarks - at minimum an "unread pages" folder. In that folder I'll create the unread bookmarks. When the user marks the item as read, it will be removed from that folder. So that's what I'm trying to do... any help will be greatly appreciated, even if it's just pointing me to some good examples. UPDATE: ...<script> function display(tree){ document.getElementById("Output").innerHTML = tree; } function start(){ chrome.bookmarks.getTree(display); } </script> </head> <body> <h4 id="Output"></h4> <script> start(); </script> ... That displays [object Object], that suggests (at least to me with a limited JavaScript experience) that an object exists. But how to access the members of that object? changing tree to tree.id or any other of what look to be parameters displays "undefined".

  • Flex fixed and variable height - can it be set in markup?

    - by Prutswonder
    I've got the following Flex application markup: <app:MyApplicationClass xmlns:app="*" width="100%" height="100%" layout="vertical" horizontalScrollPolicy="off" verticalScrollPolicy="off"> <mx:VBox id="idPageContainer" width="100%" height="100%" verticalGap="0" horizontalScrollPolicy="off" verticalScrollPolicy="off"> <mx:HBox id="idTopContainer" width="100%" height="28" horizontalGap="2"> (top menu stuff goes here) </mx:HBox> <mx:HBox id="idBottomContainer" width="100%" height="100%" verticalScrollPolicy="off" clipContent="false"> (page stuff goes here) </mx:HBox> </mx:VBox> </app:MyApplicationClass> When I run it, it displays top panel with a fixed height, and a bottom panel with variable height. I expect the bottom panel's height to contain the remaining height, but it somehow overflows off-page. The only way I found to fix this height issue (so far) is to programmatically set the height to be fixed instead of variable: <mx:HBox id="idBottomContainer" width="100%" height="700" verticalScrollPolicy="off" clipContent="false"> (page stuff goes here) </mx:HBox> And code-behind: package { import mx.containers.HBox; import mx.core.Application; import mx.events.ResizeEvent; // (...) public class MyApplicationClass extends Application { public var idBottomContainer:HBox; // (...) private function ON_CreationComplete (event:FlexEvent) : void { // (...) addEventListener(ResizeEvent.RESIZE, ON_Resize); } private function ON_Resize (event:Event) : void { idBottomContainer.height = this.height - idTopContainer.height; } } } But this solution is too "dirty" and I'm looking for a more elegant way. Does anyone know an alternative?

  • ASP.NET MVC3 - Bug using Javascript

    - by ebb
    Hey there, I'm trying to use Ajax.BeginForm() to POST A Json result from my controller (I'm using MVC3). When the Json result is called it should be sent to a javascript function and extract the object using "var myObject = content.get_response().get_object();", However it just throws a "Microsoft JScript runtime error: Object doesn't support this property or method" when trying to invoke the Ajax POST. My code: Controller: [HttpPost] public ActionResult Index(string message) { return Json(new { Success = true, Message = message }); } View: <!DOCTYPE html> <html> <head> <script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/MicrosoftAjax.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/MicrosoftMvcAjax.js")" type="text/javascript"></script> <script type="text/javascript"> function JsonAdd_OnComplete(mycontext) { var myObject = mycontext.get_response().get_object(); alert(mycontext.Message); } </script> </head> <body> <div> @using(Ajax.BeginForm("Index", "Home", new AjaxOptions() { HttpMethod = "POST", OnComplete = "JsonAdd_OnComplete" })) { @Html.TextBox("message") <input type="submit" value="SUBMIT" /> } </div> </body> </html> The strange thing is that the exactly same code works in MVC2 - Is this a bug, or have I forgot something? Thanks in advance.

  • Facebook Open Graph - post to all approved users feeds.

    - by simnom
    Hi, I'm struggling to get to grips with posting a feed item to all the members of an approved application. Within the application settings for the user it is stating that the application has permission to post to the wall but I can only achieve this if that user is currently logged in to facebook. Obviously I would like this to function so that any items I uploaded are posted to all the members of the application at any one time. I am using the Facebook PHP SDK from http://github.com/facebook/php-sdk/ and currrently my code is as follows: require 'src/facebook.php'; //Generates access token for this transaction $accessToken = file_get_contents("https://graph.facebook.com/oauth/access_token?type=client_cred&client_id=MyAppId&client_secret=MySecret"); //Gets the full user details as an object $contents = json_decode(file_get_contents("https://graph.facebook.com/SomeUserId?scope=publish_stream&" . $accessToken)); print_r($contents); if ($facebook->api('/' . $contents->id . '/feed', 'POST', array( 'title' => 'New and Improved, etc - 12/03/2010', 'link' => 'http://www.ib3.co.uk/news/2010/03/12/new-and-improved--etc', 'picture' => 'http://www.ib3.co.uk/userfiles/image/etc-booking.jpg', 'scope' => 'publish_stream' ) )==TRUE) { echo "message posted"; } else { echo "message failed"; } The output from $contents shows the expected user details but nothing relating to the permissions for my application. Am I missing a trick here? Then using the $facebook-api() function I am receiving a #200 - Permissions error. The application does not have permission to perform this action. This is driving me a little potty as I suspect I'm missing something straightforward with the authorisation but what? Many thanks in advance for an assistance offered.

  • JQuery autocomplete problem

    - by heffaklump
    Im using JQuerys Autocomplete plugin, but it doesn't autocomplete upon entering anything. Any ideas why it doesnt work? The basic example works, but not mine. var ppl = {"ppl":[{"name":"peterpeter", "work":"student"}, {"name":"piotr","work":"student"}]}; var options = { matchContains: true, // So we can search inside string too minChars: 2, // this sets autocomplete to begin from X characters dataType: 'json', parse: function(data) { var parsed = []; data = data.ppl; for (var i = 0; i < data.length; i++) { parsed[parsed.length] = { data: data[i], // the entire JSON entry value: data[i].name, // the default display value result: data[i].name // to populate the input element }; } return parsed; }, // To format the data returned by the autocompleter for display formatItem: function(item) { return item.name; } }; $('#inputplace').autocomplete(ppl, options); Ok. Updated: <input type="text" id="inputplace" /> So, when entering for example "peter" in the input field. No autocomplete suggestions appear. It should give "peterpeter" but nothing happens. And one more thing. Using this example works perfectly. var data = "Core Selectors Attributes Traversing Manipulation CSS Events Effects Ajax Utilities".split(" "); $("#inputplace").autocomplete(data);

  • FileHelpers cannot map converted field into destination array

    - by jaffa
    I have the following record (reduced for brevity): [DelimitedRecord(",")] [IgnoreFirst] [IgnoreEmptyLines()] public class ImportRecord { [FieldQuoted] [FieldTrim(TrimMode.Both)] public string FirstName; [FieldQuoted] [FieldTrim(TrimMode.Both)] public string LastName; [FieldQuoted] [FieldTrim(TrimMode.Both)] [FieldOptional] [FieldConverter(typeof(TestPropertyConverter))] public int[] TestProperty; } Converter code: public class TestPropertyConverter : ConverterBase { public override object StringToField(string from) { var ret = from.Split('|').Select(x => Convert.ToInt32(x)).ToArray(); return ret; } } So an example record could be: John, Smith, 1|2|3|4 It would expect the values 1,2,3,4 to expand and fill the TestProperty array. However, I'm getting the following exception: At least one element in the source array could not be cast down to the destination array type. I've tried to debug into the code and it seems to blow-up in the ExtractFieldValue() function inside FieldBase.cs where it tries to return out of the function. The following line seems to be the culprit: res.ToArray(ArrayType); It seems to expect the 'res' variable to be the destination type array, but it contains 1 element of the array itself. Can anyone suggest if I'm doing this wrong or a possible fix?

  • Run a flash movie in flex application.

    - by Irwin
    I've a flash movie that I would like to use inside of a flex application, very similar to a preloader. Looking at this tutorial, http://www.flexer.info/2008/02/07/very-first-flex-preloader-customization/, I expected it would be a matter of not extending "Preloader" and extending "Sprite" and using the class i created wherever i needed. Alas, the movie I created, is not being shown. This is the code for my class containing the movie, made based on the tutorial above: package { import mx.preloaders.DownloadProgressBar; import flash.display.Sprite; import flash.events.ProgressEvent; import flash.events.Event; import mx.events.FlexEvent; import flash.display.MovieClip; public class PlayerAnimation extends Sprite { [Embed("Player.swf")] public var PlayerGraphic:Class; public var mc:MovieClip; public function PlayerAnimation():void { super(); mc = new PlayerGraphic(); addChild(mc); } public function Play():void { mc.gotoAndStop(2); } } }

  • Apply CSS style to anchor problem

    - by Jake
    Using jquery I have a clicking tab mechanism that are nothing but anchor tags that return false but call javascript functions to run some events on the page. The problem is I am using jquery to apply an opacity style to the active anchor. and the other sibling anchor get a lesser opacity view. My code looks like this $("#menutab li a").click(function(){ $(this).animate({opacity:'1'},1000); $(this).siblings().animate({opacity:'.25'},1000); } I would think this code would act only on the clicked element and apply that css style to that element and the other style to the other anchor tags except the clicked one. It kind of does that, but also what it does is leave the earlier clicked element to opacity =1, so if I click an element it sets it opacity to 1 and then if I click another one it sets it opacity to 1 while leave the earlier clicked one to 1 also instead of setting it to .25 like the others. Edit: I changed the above code to: $("#menutab ul li").click(function(){ $(this).children().animate({opacity:'1'},1000); $(this).siblings().children().animate({opacity:'.25'},1000); }); and now I get the desired effect, except that when the first anchor in the list is clicked doesn't follow the event rules, When the first one is clicked its as if, the click event is not triggered, because no opacity style changes. which I don't understand.

  • Delete ONE SPECIFIC table of a database - leave the rest intact

    - by Jayomat
    Hi, I have a database where I store two different kinds of data. One table is for favorite routes, the other stores the retrieved routes from a server. I can retrieve the routes etc just fine. But after retrieving the first Route, pressing back or HOME, and then retrieving another route, the routes table is filled with all the old routes plus the new ones. So my question: how do I delete ONLY the routes table and not the whole database because I don't want to delete the added favorites....?! I found the following function in the android docs: public int delete (String table, String whereClause, String[] whereArgs) and I tried to implement it, but I must pass a SQLiteDataBase as an argument. But how? I implemented: public void deleteTableRoutes(SQLiteDataBase db){ db.delete("routes", null, null); } But I want to call this function from a different class where I have no reference to the database.. so what do I have to pass as an argument? Or how do I get a reference to my database? I build my database upon the code example of the NotePadExample from the dev docs. How to solve this problem? thanks

  • Meaning of Execute_priv on mysql.db table

    - by Ben Reisner
    I created user 'restriceduser' on my mysql server that is 'locked down'. The mysql.user table has a N for all priveledges for that account. The mysql.db table has Y for only Select, Insert, Update, Delete, Create, Drop; all other privileges are N for that account. I tried to create a stored procedure and then grant him access to run only that procedure, no others, but it does not work. The user receives: Error: execute command denied to user 'restricteduser'@'%' for routine 'mydb.functionname' The stored procedure: CREATE DEFINER = 'restriceduser'@'%' FUNCTION `functionname`(sIn MEDIUMTEXT, sformat MEDIUMTEXT) RETURNS int(11) NOT DETERMINISTIC CONTAINS SQL SQL SECURITY DEFINER COMMENT '' BEGIN .... END; The grant statement I tried: GRANT EXECUTE ON PROCEDURE mydb.functionname TO 'restricteduser'@'%'; I was able to work around by modifying his mysql.db entry with update mysql.db set execute_priv='Y' where user='restricteduser' This seems to be more then I want, because it opens up permissions for him to run any stored procedure in that database, while I only wanted him to have permissions to run the designated function. Does anyone see where my issue may lie?

  • Why would the value of the Session object go away?

    - by Michael
    In ASP.NET/VB.NET 2005 I've created a small web app with two forms. In Default there is a button and a text box and a link. When you press the button whatever is in the text box is put into the Session. Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click System.Web.HttpContext.Current.Session("mykey") = Me.TextBox1.Text End Sub When you press the link it's NavigateURL property is "~/Retrieve.aspx" On the Retrieve page it pulls the information out of the Session (that is, whatever you typed in the text box). Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim myValue As String = CType(System.Web.HttpContext.Current.Session("mykey"), String) Response.Write(myValue) End Sub Now it works on my machine and when deployed to the production web-site server if I run the browser remotely there it works fine - What you type on the first page appears on the second page. But when I run it from my machine to the production web server the second page is always blank. Why? It doesnt seem like a timeout issue - brand new web.config taking the defaults. Any pointers would be greatly appreciated! Thanks!

  • How to classify NN/NNP/NNS obtained from POS tagged document as a product feature

    - by Shweta .......
    I'm planning to perform sentiment analysis on reviews of product features (collected from Amazon dataset). I have extracted review text from the dataset and performed POS tagging on that. I'm able to extract NN/NNP as well. But my doubt is how do I come to know that extracted words classify as features of the products? I know there are classifiers in nltk but I don't know how I should use it for my project. I'm assuming there are 2 ways of finding whether the extracted word is a product feature or not. One is to compare with a bag of words and find out if my word exists in that. Doubt: How do I create/get bag of words? Second way is to implement some kind of apriori algorithm to find out frequently occurring words as features. I would like to know which method is good and how to go about implementing it. Some pointers to available softwares or code snippets would be helpful! Thanks!

  • How to access elements in a complex list?

    - by Martin
    Hi, it's me and the lists again. I have a nice list, which looks like this: tmp = NULL t = NULL tmp$resultitem$count = "1057230" tmp$resultitem$status = "Ok" tmp$resultitem$menu = "PubMed" tmp$resultitem$dbname = "pubmed" t$resultitem$count = "305215" t$resultitem$status = "Ok" t$resultitem$menu = "PMC" t$resultitem$dbname = "pmc" tmp = c(tmp, t) t = NULL t$resultitem$count = "1" t$resultitem$status = "Ok" t$resultitem$menu = "Journals" t$resultitem$dbname = "journals" tmp = c(tmp, t) Which produces: str(tmp) List of 3 $ resultitem:List of 4 ..$ count : chr "1057230" ..$ status: chr "Ok" ..$ menu : chr "PubMed" ..$ dbname: chr "pubmed" $ resultitem:List of 4 ..$ count : chr "305215" ..$ status: chr "Ok" ..$ menu : chr "PMC" ..$ dbname: chr "pmc" $ resultitem:List of 4 ..$ count : chr "1" ..$ status: chr "Ok" ..$ menu : chr "Journals" ..$ dbname: chr "journals" Now I want to search through the elements of each "resultitem". I want to know the "dbname" for every database, that has less then 10 "count" (example). In this case it is very easy, as this list only has 3 elements, but the real list is a little bit longer. This could be simply done with a for loop. But is there a way to do this with some other function of R (like rapply)? My problem with those apply functions is, that they only look at one element. If I do a grep to get all "dbname" elements, I can not get the count of each element. rapply(tmp, function(x) paste("Content: ", x))[grep("dbname", names(rapply(tmp, c)))] Does someone has a better idea than a for loop? Thanx, Martin

  • Magento Replacing super attributes table with dropdown

    - by thrice801
    Hi, I am trying to replace my magento super attributes table with a drop down menu in place of it, Ive got the menu created but I am struggling to get it to actually use the data from the select dropdown. On submit it calls up function productAddToCartForm, which I feel like if I could modify, I could figure it out. But I have no idea where that function is. My php code looks like the following. <?php if (count($_associatedProducts)): ?> <select name="selectedSku"> <?php foreach ($_associatedProducts as $_item): ?> <?php $prodname = $this->htmlEscape($_item->getName()); $prodprice = $this->htmlEscape($_item->getPrice()); $prodcolor = $_item->getFullColor(); $prodsize = $_item->getTopSize(); $prodcombined = $prodname; $prodcombined .= " / "; $prodcombined .= $prodprice; echo "<option "; echo "value ='"; echo $_item->getId(); echo "'>"; echo $prodcombined; echo "</option>"; ?> <?php endforeach; ?> </select> Any help would be much appreciated.

  • ASP .NET, Javascript, AjaxControlToolkit render results with Selenium?

    - by Seth
    I'm a newbie to web stuff. However, I wish to scrape some data from multiple websites. I'm currently using the following technologies: Selenium; Python; and BeautifulSoup; I believe the site I am trying to scrape is using a combination of ASP.NET, javascript and the AjaxControlToolkit. I believe the key results I am looking for are in the following script: <script type="text/javascript"> //<![CDATA[ Sys.Application.initialize(); Sys.Application.add_init(function() { $create(AjaxControlToolkit.AutoCompleteBehavior, {"completionInterval":50,"completionListCssClass":"autocomplete_completionListElement","completionListItemCssClass":"autocomplete_listItem","completionSetCount":20,"delimiterCharacters":"","highlightedItemCssClass":"autocomplete_highlightedListItem","id":"ctl00_ContentPlaceHolder1_AutoCompleteExtender1","minimumPrefixLength":4,"serviceMethod":"GetSchoolNames","servicePath":"AutoComplete.asmx"}, {"itemSelected":ItemSelected}, null, $get("ctl00_ContentPlaceHolder1_SchoolNameTextBox")); }); Sys.Application.add_init(function() { $create(AjaxControlToolkit.AutoCompleteBehavior, {"completionInterval":50,"completionListCssClass":"autocomplete_completionListElement","completionListItemCssClass":"autocomplete_listItem","delimiterCharacters":"","highlightedItemCssClass":"autocomplete_highlightedListItem","id":"ctl00_ContentPlaceHolder1_AutoCompleteExtender2","minimumPrefixLength":2,"serviceMethod":"GetSuburbNames","servicePath":"AutoComplete.asmx"}, null, null, $get("ctl00_ContentPlaceHolder1_SuburbTownTextBox")); }); //]]> </script> Is there an easy way to get the results of the above script processed using Selenium so that I may pass it using BeautifulSoup?

  • Fading out everything but (this) - while honoring a click()

    - by Kasper Lewau
    I'm trying to achieve a fading navigation system, where everything in the nav but the element being hovered will fade out to say, 0.3 opacity. At the same time, I want clicks to have a greater "value", so as to not fade out a clicked element (or in this case, the active subpage).. That didn't make much sense to me either, I'll just post the code I have. <nav id="main"> <ul> <li> <a>work</a> </li> <li> <a>about me</a> </li> <li> <a>contact</a> </li> </ul> </nav> And the script that makes it sparkle: var nava = "nav#main ul li a"; $(nava).hover(function(){ $(nava).not(this).removeClass().addClass("inactive"); $(this).addClass("active"); }); $(nava).click(function(){ $(this).removeClass().addClass("active"); }); }); And the classes / css(less): .inactive{color:@color2; border-bottom:0 solid #000;} .active{color:@color1; border-bottom:1px solid #000;} nav#main ul li a{color:@color1;} Basically the hover states take priority over the click, which I do not want to happen. Ideally I'd like for all of the anchor elements to revert to its original state whenever you hover out from the unordered list holding it all. If anyone has some pointers on this it'd be greatly appreciated. Cheers!

  • Prototypal inheritance should save memory, right?

    - by Techpriester
    Hi Folks, I've been wondering: Using prototypes in JavaScript should be more memory efficient than attaching every member of an object directly to it for the following reasons: The prototype is just one single object. The instances hold only references to their prototype. Versus: Every instance holds a copy of all the members and methods that are defined by the constructor. I started a little experiment with this: var TestObjectFat = function() { this.number = 42; this.text = randomString(1000); } var TestObjectThin = function() { this.number = 42; } TestObjectThin.prototype.text = randomString(1000); randomString(x) just produces a, well, random String of length x. I then instantiated the objects in large quantities like this: var arr = new Array(); for (var i = 0; i < 1000; i++) { arr.push(new TestObjectFat()); // or new TestObjectThin() } ... and checked the memory usage of the browser process (Google Chrome). I know, that's not very exact... However, in both cases the memory usage went up significantly as expected (about 30MB for TestObjectFat), but the prototype variant used not much less memory (about 26MB for TestObjectThin). I also checked: The TestObjectThin instances contain the same string in their "text" property, so they are really using the property of the prototype. Now, I'm not so sure what to think about this. The prototyping doesn't seem to be the big memory saver at all. I know that prototyping is a great idea for many other reasons, but I'm specifically concerned with memory usage here. Any explanations why the prototype variant uses almost the same amount of memory? Am I missing something?

  • Simple jQuery toggle() and return false inside click()

    - by Casey Stark
    I'm mostly a djangonaut and phper, but I'm getting javascript development. I've been looking at this very simple block for a feedback widget on a page. The code is pretty self-explanatory. <a id="feedback-widget-toggle" href="[feedback_url]">Feedback</a> <div id="feedback-widget"> <form method="POST" action="[form_url]"> ... </form> </div> <script type="text/javascript"> $(document).ready(function() { $("#feedback-widget-toggle").click(function() { $("#feedback-widget").toggle("slide", {}, 500); return false; }); }); </script> It's really simple. So simple that I feel pretty dumb for this one. The jQuery is just supposed to disable the link and slide out the feedback-widget div. That's it. I'm new to jQuery, so it's probably some very simple syntax error that I'm not sure how to debug well enough. Thanks.

  • What is a NULL value

    - by Adi
    I am wondering , what exactly is stored in the memory when we say a particular variable pointer to be NULL. suppose I have a structure, say typdef struct MEM_LIST MEM_INSTANCE; struct MEM_LIST { char *start_addr; int size; MEM_INSTANCE *next; }; MEM_INSTANCE *front; front = (MEM_INSTANCE*)malloc(sizeof(MEM_INSTANCE*)); -1) If I make front=NULL. What will be the value which actually gets stored in the different fields of the front, say front-size ,front-start_addr. Is it 0 or something else. I have limited knowledge in this NULL thing. -2) If I do a free(front); It frees the memory which is pointed out by front. So what exactly free means here, does it make it NULL or make it all 0. -3) What can be a good strategy to deal with initialization of pointers and freeing them . Thanks in advance

  • Using jQuery tools from within GWT -- is there a way to allow exchanges?

    - by culov
    I have a GWT web-app with a nearly full page Google map window. Inside the the map, I have infowindows which include links. What I want to do is use jquery tools overlays (http://flowplayer.org/tools/overlay/apple.html) to open the overlay and display it on top of the map once the link inside the info window is clicked. Now, the link source is generated dynamically, and it is hosted on a different server, so i have to open it in an iframe and set the source of the iframe before it opens. this seems simple enough since i only have 1 iframe on the page: function changeSource(url){ $("#menuIFrame").attr("src",url); } To call this before opening the overlay (which is done on mouse release), i create the following element in the google maps infowindow via GWT: <a href="http://whatever.com/menu/" onClick="changeSource('http://whatever.com/menu/');" rel=#menu"> View menu </a> Jquery tools works by opening whatever div has the id assigned to the value of 'rel', but because i have my javascript/jquery on my LandingPage.html in GWT, there appears to be some sort of disconnect between the two because the changeSource function is never called AND the overlay is never added to the window. Here's my app: http://truxmapper.appspot.com/ As you can see, the other overlays will work fine, but once you click an infowindow and try to view the menu, it will simply use the href to open the url in that window. Does anyone know of a solution that will allow me to accomplish my goal? Thanks!

  • jquery-ui autocomplete with ASP MVC suggestions not displaying

    - by adamnickerson
    I have been trying to get a simple example of the jquery-ui autocomplete to work. I have a controller setup to handle the query, and it returns the json that looks to be in order, but I am getting no suggestions showing up. Here are the js libraries I am including: <script type="text/javascript" language="javascript" src="/Scripts/jquery-1.4.1.js"></script> <script type="text/javascript" language="javascript" src="/Scripts/jquery-ui-1.8.1.custom.min.js"></script> <link href="/Content/jquery-ui-1.8.1.custom.css" rel="stylesheet" type="text/css" /> and here is the javascript and the form tags: <script type="text/javascript"> $(function () { $("#organization").autocomplete({ source: function (request, response) { $.ajax({ url: '/Organization/OrganizationLookup', dataType: "json", data: { limit: 12, q: request.term } }) }, minLength: 2 }); }); </script> <div class="ui-widget"> <label for="organization">Organization: </label> <input id="organization" /> </div> I get back a json response that looks reasonable from my controller: [{"id":"Sector A","value":"Sector A"},{"id":"Sector B","value":"Sector B"},{"id":"Sector C","value":"Sector C"}] id and value seem to be the default naming that autocomplete is looking for. But I get no joy at all. Any thoughts?
