• jQuery: How to determine which <li> tag was clicked?

  - by user337909

  I am creating a form with 5 lines of text, and each text I am allowing the user to select if they want the text to be centered, left, or right justified. I have a unnumbered list with list elements x5. <li><img src="images/justify_left.png" alt="left" /><span>Justify Left</span></li> <li><img src="images/justify_center.png" alt="center" /><span>Justify Left</span></li> <li><img src="images/justify_right.png" alt="right" /><span>Justify Left</span></li> Each of the 5 set of <li> items refers to its respective line. With jQuery, how would I go about determining which of the 15 <li> items did the user select so that I can correspond the proper justification as a post method?

• AJAX Panel not throwing exceptions

  - by Grant

  Hi, i have just noticed something strange in some asp.net markup. I have a standard form with a couple of textboxes and a submit button. When clicked the code behind will attempt to perform some logic and then return. If the input values are not valid it used to throw an exception. The moment i wrapped the controls in an AJAX update panel and try to submit bad data, no exception is thrown and the panel returns like nothing was wrong. Does anyone know how to return this to the previous behavior whilst keeping the update panel?

• Updating external Flex components from an action

  - by Scott

  Hello, I'm new to Flex and am having trouble understanding Events. I think Events are what I want to use for my situation. I have 2 components, addUser.mxml and listUsers.mxml. I access these from a ViewStack in my main application. When I load listUsers.mxml it shows a list of current users in a datagrid via a HTTPService call. When I add a user using the form on addUser.mxml I would like the datagrid in listUsers.mxml to refresh when I return to that view to show the new user. I've tried several different things with addEventListener and dispatchEvent but can't seem to get it working. Can someone help me with this logic?

• Facebook access_token: how do I get it once the user accepted my app?

  - by hoktar

  When a user visits my site which contains a facebook app the first time, it requires him to allow it and he gets promted to do that, then I get the code which I can convert to an access_token. So far so good. But how do I get the token once the user has already visited the site? As long as this token form the first time is active everything is fine. But how do I get another token when the user had already allowed the app a week ago and is only visiting my page again?

• Ruby On Rails - Collection Select - MYSQL Database - Problem Displaying ampersand ("&")

  - by dbkbaki

  I am having an annoying problem displaying the labels of a select box correctly where there is an ampersand contained within the label string. On a form being rendered with the form_for helper the collection_select reads data from a Mysql 5.075 database the text stored in the database is "Surabaya & Surrounding Areas" when rendered and displayed in firefox 3.6 or safari is is displaying as "Surabaya %amp; Surrounding Areas". The code used to render the select is as follows: <%= f.collection_select :parent_id, Destination.roots, :id, :name, {:include_blank => true} %> I have tried adding a h(:name) and also storing && in the database but it still will not display the ampersand correctly. Have searched on google for what I thought would be a simple solution but cant find anything that solves this. Using ROR 2.3.5/Ruby 1.8.7 If anyone has a solution it will be much appreciated. many thanks, David

• beforeSave() returned some error

  - by kwokwai

  Hi all, I got a simple input text field in a HTML form: <input type="text" name="data[User][pswd]" id="data[User][pswd]"> The scripts for the Controller's action that captured the data is as follows: function register(){ $temp = $this->data; if(strlen($temp['User']['pswd'])>6) { if ($this->User->save($this->data)) { $this->Session->setFlash('Data was Saved'); } } } // this script works And in the Model controller, I got these lines of codes: function beforeSave() { $raw = $this->data; if(strlen($raw['User']['pswd'])>6){ md5($raw['User']['pswd']); } return true; } // this script failed to work The data was stored into the Database successfully but it was not undergone any MD5 encryption. I think that there must be some errors in the Model's script because I saw some errors flashed after the data was saved, but the screen that showed the errors immediately refreshed in a second after the data was saved successfully and I couldn't see the detail of the errors that caused the problem. Could you help me out please?

  - by smoove666

  Something that bugs me for a long time: I want to convert this Array: // $article['Tags'] array(3) { [0] => array(2) { ["id"] => string(4) "1" ["tag"] => string(5) "tag1" }, [1] => array(2) { ["id"] => string(4) "2" ["tag"] => string(5) "tag2" }, [2] => array(2) { ["id"] => string(4) "3" ["tag"] => string(5) "tag3" }, } To this form: // $extractedTags[] array(3) { [0] => string(4) "tag1", [1] => string(4) "tag2", [2] => string(4) "tag3", } currently i am using this code: $extractedTags = array(); foreach ($article['Tags'] as $tags) { $extractedTags[] = $tags['tag']; } Is there any more elegant way of doing this, maybe a php built-in function?

• jquery - turning "autocomplete" to off for all forms (even ones not loaded yet)

  - by matthewsteiner

  So, I've got this code: $(document).ready(function(){ $('form').attr('autocomplete', 'off'); }); It works great for all forms already existing. The problem is, some forms of mine are in pop ups loaded throught ajax. This won't apply to them since they're "loaded" later. I know there's a live() function - but that's only for attaching events. What's a good way to apply this to all forms? Thanks.

When window is closed and asterisk is still there, a promote "Would you like to save changes" appears. If then saved the asterisk disappear. What do real applications use to create their application file? (Note: I'm not looking for database saving or SQL) I'm just looking for hints and guidelines. Thank you.

• Do you have to call .Save() when modifying a application setting that is bound to a control property

  - by Jordan S

  I am programming in .NET I have an application setting of type string. On my form I have a textbox. I bound the text property of the textbox to my application setting. If I type something in the textbox it changes the value that is held in the Application setting but the next time I start the program it goes back to the default value. Do I need to call Properties.Settings.Default.Save(); after the text is entered for the new value to be saved? Shouldn't it do this automatically? Is there a way I can make it do it automatically?

• Sphinx without using an auto_increment id

  - by squeeks

  I am current in planning on creating a big database (2+ million rows) with a variety of data from separate sources. I would like to avoid structuring the database around auto_increment ids to help prevent against sync issues with replication, and also because each item inserted will have a alphanumeric product code that is guaranteed to be unique - it seems to me more sense to use that instead. I am looking at a search engine to index this database with Sphinx looking rather appealing due to its design around indexing relational databases. However, looking at various tutorials and documentation seems to show database designs being dependent on an auto_increment field in one form or another and a rather bold statement in the documentation saying that document ids must be 32/64bit integers only or things break. Is there a way to have a database indexed by Sphinx without auto_increment fields as the id?

• Output of Iterable.sliding as Tuple

  - by ziggystar

  The method sliding on collections returns a sliding window of given size in the form of X[Iterable[A]] with X being the type of the collection and A the element type. Often I need two or three elements and I prefer to have them named. One ugly workaround for sliding(2) is the following: points.sliding(2).foreach{ twoPoints => val (p1,p2) = (twoPoints.head,twoPoints.last) //do something } This sucks and only works for two elements. Also note that (a,b) = (twoPoints(0),twoPoints(1)) doesn't work. Help me!

• Adding characters to string

  - by Jamza

  I am currently trying to build a very basic serial shell with my arduino. I am able to get an output from the device using Serial.read() and can get the character it has outputted, but I cannot work out how to then add that character to a longer to form the full command.

• Implementing "select distinct ... from ..." over a list of Python dictionaries

  - by daveslab

  Hi folks, Here is my problem: I have a list of Python dictionaries of identical form, that are meant to represent the rows of a table in a database, something like this: [ {'ID': 1, 'NAME': 'Joe', 'CLASS': '8th', ... }, {'ID': 1, 'NAME': 'Joe', 'CLASS': '11th', ... }, ...] I have already written a function to get the unique values for a particular field in this list of dictionaries, which was trivial. That function implements something like: select distinct NAME from ... However, I want to be able to get the list of multiple unique fields, similar to: select distinct NAME, CLASS from ... Which I am finding to be non-trivial. Is there an algorithm or Python included function to help me with this quandry? Before you suggest loading the CSV files into a SQLite table or something similar, that is not an option for the environment I'm in, and trust me, that was my first thought.

• Visual Basic Display Square

  - by user1724157

  Alright I'm currently lost on a particular assignment I have for a class. I've seen many examples of this app but none of them see to help my problem is as follows: Write a Sub procedure "DisplaySquare" to display the solid square. The size should be specified by the integer parameter "size". The character that fills the square should be specified by the string parameter "fillCharacter. Use a For...Next statement nested within another For...Next statement to create the square. The outer For...Next specifies what row is currently being displayed. The inner For...Next appends all the characters that form the row to a display string. So it should come out like as follows: if a user enters "8" and "#" ######## ######## ######## ######## ######## ######## ######## ######## Any help would be appreciated.

• How do I gather a class' css attributes given nothing but the className?

  - by user1128571

  For example I might have some css stuff that looks like this: .divType1 { position: absolute; width: 60px; height: 60px; left: 400px; top: 100px; border: 1px solid #89B; z-index: 0; } Now within Javascript I want to gather div class divType1' css attributes, but am provided only with the div class, so I can't do something of form ( pseudo-code ): selectDivWithClass( divType1 ).getCss(left). I could hack something by instantiating a div with class divType1 and grab its css attributes, and then destroy it, but is there a better way?

• How to overwrite virtual fnc in good style? [C++]

  - by atch

  Hi, guys I know this question is very basic but I've met in few publications (websites, books) different style of overwriting virtual function. What I mean is: if I have base class: class Base { public: virtual void f() = 0; }; in some publications I saw that to overwrite this some authors would just say: void f(); and some would still repeat the virtual keyword before void. Which form of overwriting is in good style? Thank you for your answers.

• "Refreshing" an XML feed on iPhone/Mac OSX

  - by Steve

  Hi all, I'm curious for those of you who are building iPhone apps based on REST/SOAP/XML-RPC or simply pulling down a dynamic XML feed, what does it mean exactly to you when a user says 'refresh' the feed? The straight forward way is to populate some collection, say an NSMutableArray, with whatever you bring down from the feed. If a widget on the UI is available to refresh, I typically do something like: [myMutableArray removeAllObjects]; // follow steps to repopulate myMutableArray It seems this is the least efficient algorithm for refreshing an XML feed. For instance many folks who are building Twitter clients, are appending changes to their existing feed, versus bringing down the entire feed in its complete form again. What kind of algorithms are you using to "refresh" your models when speaking to a server-side data source? Thanks all.

• Selecting radiobuttons populated within asp.net RadioButtonList with jQuery

  - by user194881

  Hello and thanks in advance for the communal help I always find here. I have been tinkering around with what should seem a pretty straight forward task even for a jQuery newb as myself. I have a radiobuttonlist control bound to a collection: <asp:RadioButtonList ID="radBtnLstPackageSelector" runat="server" CssClass="PackageS"> </asp:RadioButtonList> My form does have several other controls of the same type; Now, the challenge is to select and wire up a on Click event for every radiobutton from the radBtnLstPackageSelector. I have tried several approaches such as: var results1 = $(".PackageS").children("input"); var results1 = $(".PackageS").children("input[type=radiobutton"); var results1 = $("table.PackageS > input[type=radiobutton"); with no luck... Your help would be great right now! ~m
