  • jQuery - Trigger click event on links with spacebar?

    - by Herb Caudill
    It looks like in most browsers, an <input type="submit"> treats both [spacebar] and [enter] as a click, but an <a> link only treats [enter] as a click. My app uses a number of links formatted to simulate buttons, so a user that is accustomed to tabbing to a button and pressing [spacebar] will be frustrated. This bit of jQuery solves the problem: $("a.Button").die("keypress").live("keypress", function(e) { if (e.which == 32) { $(this).trigger("click"); e.preventDefault(); } }); My question: Is this a reason not to do this? I'm a little reluctant to override the browser's default behavior on something as basic as this, but since I'm already abusing the link tag to make it look like a button, at least this way I'm not violating the user's expectations any further.

  • create table based on a user defined type

    - by Glen
    Suppose I have a user defined type: CREATE OR REPLACE TYPE TEST_TYPE AS OBJECT ( f1 varchar2(10), f2 number(5) ); Now, I want to create a table to hold these types. I can do the following: create table test_type_table ( test_type_field test_type ); This gives me a table with one column, test_type_field. Is there an easy and automated way to instead create a table such that it has 2 columns, f1 and f2?. So that it's the equivilent to writing: create table test_type_table ( f1 varchar2(10), f2 number(5) );

  • File system to choose for NAS box based on FreeNAS or OpenFiler [closed]

    - by Chris
    I'm a photographer and I have a requirement find a better method of storing my photos other than multiple USB2 drives via USB hubs. Currently I use a Macbook Pro and 6 external drives connected via USB2 or FW800. 3 are a copy of the first three, kept up to day manually by running an rsync backup. I'd like to run a FreeNAS or OpenFiler NAS box using 2TB drives mirrored via software RAID. But - I would like to have the flexibility of also plugging into the drive physically for the faster throughput when necessary. So. My question is, is there a file system that both *nix and Mac OSX will play nice with? Many thanks, Chris.

  • Caching view-port based Geo-queries

    - by friism
    I have a web app with a giant Google Map in it. As users pan and zoom around on the map, points are dynamically loaded through AJAX call which include the viewport bounds (NE and SW corner coordinates) and some other assorted parameters. How do I cache these request for points? The problem is that the parameters are highly variable and (worst) not discrete i.e. floats with a lots of decimal places. I'm using ASP.NET-MVC/C#/LINQ2SQL/SQL-Server but the problem is not tied to that platform. This is the signature of the the relevant method: [AcceptVerbs(HttpVerbs.Post)] public JsonResult Data(string date, string categories, string ne_lat, string ne_lng, string sw_lat, string sw_lng)

  • WCF REST based services authentication schemes

    - by FlySwat
    I have a simple authentication scheme for a set of semi-public REST API's we are building: /-----------------------\ | Client POST's ID/Pass | | to an Auth Service | \-----------------------/ [Client] ------------POST----------------------> [Service/Authenticate] | /-------------------------------\ | Service checks credentials | [Client] <---------Session Cookie------- | and generates a session token | | | in a cookie. | | \-------------------------------/ | [Client] -----------GET /w Cookie -------------> [Service/Something] | /----------------------------------\ | Client must pass session cookie | | with each API request | | or will get a 401. | \----------------------------------/ This works well, because the client never needs to do anything except receive a cookie, and then pass it along. For browser applications, this happens automatically by the browser, for non browser applications, it is pretty trivial to save the cookie and send it with each request. However, I have not figured out a good approach for doing the initial handshake from browser applications. For example, if this is all happening using a AJAX technique, what prevents the user from being able to access the ID/Pass the client is using to handshake with the service? It seem's like this is the only stumbling block to this approach and I'm stumped.

  • Setting the DataGridColumn's dataField based on XML node with the same name

    - by Rie Mino
    I am stuck. Given this XML: <matrix> <row> <column>0.51</column> <column>0.52</column> <column>0.53</column> <column>0.54</column> </row> <row> <column>0.61</column> <column>0.62</column> <column>0.63</column> <column>0.64</column> </row> I am trying to define a DataGrid such that the row nodes will represent new rows in the DataGrid and the column nodes will be used to auto-populate the DataGrid's columns. I am having a problem setting the dataField for each of the DataGridColumn ojects created. The DataGrid is created but the cell values for row 1 are all 0.51 and row 2 are 0.61. What am I doing wrong here?

  • Crashing when pushing a XIB based view controller onto navigation controller stack

    - by Michael
    I was attempting to clean up the implementation for a sub-panel on a navigation controller stack, so that the navigation bar could be customized in the XIB instead of doing it manually in the viewDidLoad method. The original (working) setup had the XIB set up with the "File's Owner" class set to the view controller class, and then the view at the top level. This works fine. In the "Interface Builder User Guide", p. 71, it describes the recommended way to build the XIBs for sub-panels ("additional navigation levels"). This approach leaves the "File's Owner" class as NSObject, but adds a UIViewController at the top level, and nests the view (and navigation item) underneath it. The UIViewController's view automatically gets connected to the contained view. When I try to push the controller init'd with this new XIB, the app crashes because of a missing view: SettingsViewController *controller = [[SettingsViewController alloc] initWithNibName:@"SettingsView" bundle:nil]; [self.navigationController pushViewController:controller animated:YES]; 2010-04-23 11:17:37.135 xxxx[1173:207] * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UIViewController _loadViewFromNibNamed:bundle:] loaded the "SettingsTestView" nib but the view outlet was not set.' I've double checked everything, and tried building a clean XIB from scratch, but get the same result. I looked through a number of the code sample projects, and NONE of them use the documented/recommended approach--they all use the File's Owner class and manually set up the navigation bar in viewDidLoad like I originally had it. Is it possible to get it working the "recommended" way? Thanks! Michael

  • XSLT transformation by grouping based on 3 elements/attributes

    - by Daniel
    This question is related to http://stackoverflow.com/questions/2863202/xslt-1-0-grouping-to-reformat-element-defined-by-date-into-element-defined-by-tas Just to understand more clearly the trick behind. How would the XSLT look like if we were to group by date, task and shift as below: Input XML; <Person> <name>John</name> <date>June12</date> <shift tier=1> <workTime taskID=1>34</workTime> <workTime taskID=2>12</workTime> </shift> <shift tier=2> <workTime taskID=1>3</workTime> </shift> </Person> <Person> <name>John</name> <date>June13</date> <shift tier=1> <workTime taskID=1>21</workTime> <workTime taskID=2>11</workTime> </shift> <shift tier=2> <workTime taskID=1>2</workTime> </shift> </Person> and similarly, the output would be <Person> <name>John</name> <tier>1</tier> <taskID>1</taskID> <workTime> <date>June12</date> <time>34</time> </worTime> <workTime> <date>June13</date> <time>21</time> </worTime> </Person> <Person> <name>John</name> <tier>1</tier> <taskID>2</taskID> <workTime> <date>June12</date> <time>12</time> </worTime> <workTime> <date>June13</date> <time>11</time> </worTime> </Person> <Person> <name>John</name> <tier>2</tier> <taskID>1</taskID> <workTime> <date>June12</date> <time>3</time> </worTime> <workTime> <date>June13</date> <time>2</time> </worTime> </Person>

  • jQuery date picker not persistant after AJAX

    - by ILMV
    So I'm using the jQuery date picker, and it works well. I am using AJAX to go and get some content, obviously when this new content is applied the bind is lost, I learnt about this last week and discovered about the .live() method. But how do I apply that to my date picker? Because this isn't an event therefore .live() won't be able to help... right? This is the code I'm using to bind the date picker to my input: $(".datefield").datepicker({showAnim:'fadeIn',dateFormat:'dd/mm/yy',changeMonth:true,changeYear:true}); I do not want to call this metho everytime my AJAX fires, as I want to keep that as generic as possible. Cheers :-) EDIT As @nick requested, below is my wrapper function got the ajax() method: var ajax_count = 0; function getElementContents(options) { if(options.type===null) { options.type="GET"; } if(options.data===null) { options.data={}; } if(options.url===null) { options.url='/'; } if(options.cache===null) { options.cace=false; } if(options.highlight===null || options.highlight===true) { options.highlight=true; } else { options.highlight=false; } $.ajax({ type: options.type, url: options.url, data: options.data, beforeSend: function() { /* if this is the first ajax call, block the screen */ if(++ajax_count==1) { $.blockUI({message:'Loading data, please wait'}); } }, success: function(responseText) { /* we want to perform different methods of assignment depending on the element type */ if($(options.target).is("input")) { $(options.target).val(responseText); } else { $(options.target).html(responseText); } /* fire change, fire highlight effect... only id highlight==true */ if(options.highlight===true) { $(options.target).trigger("change").effect("highlight",{},2000); } }, complete: function () { /* if all ajax requests have completed, unblock screen */ if(--ajax_count===0) { $.unblockUI(); } }, cache: options.cache, dataType: "html" }); } What about this solution, I have a rules.js which include all my initial bindings with the elements, if I were to put these in a function, then call that function on the success callback of the ajax method, that way I wouldn't be repeating code... Hmmm, thoughts please :D

  • XPath select an attribute based on value

    - by Apeksha
    Using VB.Net, I have an XmlNode object, xNode. I need to select an attribute of this node if it has a particular value. e.g. xNode.SelectSingleNode(".[@attr1='1']") I would expect this statement to return the attribute "attr1", only if it has a value of "1". However, I get an error - Expression must evaluate to a node-set. When I tried this - xNode.SelectSingleNode("@attr1[@attr1='1']") It always returns Nothing, even if the attribute has a value of 1. I have tried a lot of different things, but no luck yet. Please help. Thanks.

  • How to rewrite a url based on accept-language

    - by Anthony Faull
    I have a website in three languages with a directory for each: i.e. /en-US/, /de-DE/ and /fr-FR/. I would like the web server to use the browser's accept-language string to return content in the language of the user. Examples: (a) "pl-PL;fr-FR;en-US" should redirect to /fr-FR/. (b) "de;fr-FR" redirects to /de-DE/ (c) "jp-JP" redirects to /en-US/. How would I do this in an .htaccess file?

  • Correct order of overrides for a composite control based on an abstract one

    - by mattdwen
    I'm writing a set of C# composite web server controls for displaying dialog boxes. I want to have one abstract class which handles the basic layout and things like titles of the control, then have a set of derived ones which render child controls at a specific point. I forsee three distincts methods: renderOpeningHtml handled by the abstract class, renderCustomControls as done by the derived class, and renderClosingHtml by the abstract class again, except I can't figure the life cycle of a CompositeControl and what methods to use when.

  • switch between two cursors based on parameter passed into stored procedure

    - by db83
    Hi, I have two cursors in my procedure that only differ on the table name that they join to. The cursor that is used is determined by a parameter passed into the procedure if (param = 'A') then DECLARE CURSOR myCursor IS SELECT x,y,z FROM table1 a, table2 b BEGIN FOR aRecord in myCursor LOOP proc2(aRecord.x, aRecord.y, aRecord.z); END LOOP; COMMIT; END; elsif (param = 'B') then DECLARE CURSOR myCursor IS SELECT x,y,z FROM table1 a, table3 b -- different table BEGIN FOR aRecord in myCursor LOOP proc2(aRecord.x, aRecord.y, aRecord.z); END LOOP; COMMIT; END; end if I don't want to repeat the code for the sake of one different table. Any suggestions on how to improve this? Thanks in advance

  • 301 Redirecting URLs based on GET variables in .htaccess

    - by technicalbloke
    I have a few messy old URLs like... http://www.example.com/bunch.of/unneeded/crap?opendocument&part=1 http://www.example.com/bunch.of/unneeded/crap?opendocument&part=2 ...that I want to redirect to the newer, cleaner form... http://www.example.com/page.php/welcome http://www.example.com/page.php/prices I understand I can redirect one page to another with a simple redirect i.e. Redirect 301 /bunch.of/unneeded/crap http://www.example.com/page.php But the source page doesn't change, only it's GET vars. I can't figure out how to base the redirect on the value of these GET variables. Can anybody help pls!? I'm fairly handy with the old regexes so I can have a pop at using mod-rewrite if I have to but I'm not clear on the syntax for rewriting GET vars and I'd prefer to avoid the performance hit and use the cleaner Redirect directive. Is there a way? and if not can anyone clue me in as to the right mod-rewrite syntax pls? Cheers, Roger.

    I have two domain names pointing to the same ip, I am currently not using virtual host in my apache configuration. I simply use /var/www/html/ as root of the app. do I need to buy 2 godaddy certificates, one for each domain? It seems that godaddy certificate is tied to a domain, not ip, can someone clarify?

  • Emulating Dynamic Dispatch in C++ based on Template Parameters

    - by Jon Purdy
    This is heavily simplified for the sake of the question. Say I have a hierarchy: struct Base { virtual int precision() const = 0; }; template<int Precision> struct Derived : public Base { typedef Traits<Precision>::Type Type; Derived(Type data) : value(data) {} virtual int precision() const { return Precision; } Type value; }; I want a function like: Base* function(const Base& a, const Base& b); Where the specific type of the result of the function is the same type as whichever of first and second has the greater Precision; something like the following pseudocode: template<class T> T* operation(const T& a, const T& b) { return new T(a.value + b.value); } Base* function(const Base& a, const Base& b) { if (a.precision() > b.precision()) return operation((A&)a, A(b.value)); else if (a.precision() < b.precision()) return operation(B(a.value), (B&)b); else return operation((A&)a, (A&)b); } Where A and B are the specific types of a and b, respectively. I want f to operate independently of how many instantiations of Derived there are. I'd like to avoid a massive table of typeid() comparisons, though RTTI is fine in answers. Any ideas?
