  • jQuery Reference First Column in HTML Table

    - by Vic
    I have a table where all of the cells are INPUT tags. I have a function which looks for the first input cell and replaces it with it's value. So this: <tr id="row_0" class="datarow"> <td><input class="tabcell" value="Injuries"></td> <td><input class="tabcell" value="01"></td> becomes this: <tr id="row_0" class="datarow"> <td>Injuries</td> <td><input class="tabcell" value="01"></td> Here is the first part of the function: function setRowLabels() { var row = []; $('.dataRow').each(function(i) { row.push($('td input:eq(0)', this).val() + ' - '); $('td input:eq(0)', this).replaceWith($('td input:eq(0)', this).val()); $('td input:gt(0)', this).each(function(e) { etcetera But when the page reloads, the first column is not an input type, so it changes the second column to text too! Can I tell it to only change the first column, no matter what the type is? I tried $('td:eq(0)', this).replaceWith($('td:eq(0)', this).val()); but it does not work. Any suggestions appreciated! Thanks

  • how to reverse an angle

    - by MissHalberd
    I am no mathematician, but I somehow got into game development as a hobby. Having never studied anything beyond basic math, I have a lot of trouble figuring out how to reverse the angle of something, facing to the opposite direction, among the X axis. One image says more than 1000 words though (specially uneducated words): http://img156.imageshack.us/i/wihwin.png/ I basically want to reverse the direction of cannon objects adhered to a robot. When the robot changes from facing right to facing left, I do (180 - angle) as everyone suggested me, but it reverses the angle...literally, making the cannons aim up when they are aiming down. So, I need to do something else, but it escapes my knowledge. Anyone would be so kind to help me with this? Oh, I use regular C by the way, in case there's something built-in specific to it. To put it in other words, I work in 2D, so I want an angle that is facing right to face left. 0 being "totally to the right", 180 "left", 90 "up" and 270 "down". I want something that is aiming with an angle of 91 to turn into 89 when reversed, literally. There's no Z axis present. EDIT: Thanks for the answers! Trying them out now. I'll post which one worked in a minute!

  • Function Triggered before fadeOut(); is finished

    - by willmcneilly
    Hi I'm new to javascript/jQuery this really has me stumped. What I'm trying to achieve here is On toggling a#sameDayTab jquery will look for .changeAlert and fadeOut it's container div, when toggled again the div will fade in (this works well.) Each toggle will also call a function that tells me how many .changeAlert's are present on the page and updates the number appropriately in a span. The problem is when I first click the toggled anchor the number of visible should be 0 as the .changeAlert has been hidden by fadeOut instead it returns the number of classes present on page load this value never changes no matter how many times the toggle is activated. Any help greatly appreciated. function totalNumFares () { var n = $('.changeAlert:visible').size(); $('.numFares').replaceWith('<span class=\"numFares\">'+ n +'</span>'); } totalNumFares(); //Toggle On/off Same Day Connections $('a#sameDayTab').toggle(function() { $('.changeAlert').parent().parent().parent().parent().parent().fadeOut(); totalNumFares(); },function(){ $('.changeAlert').parent().parent().parent().parent().parent().fadeIn(); totalNumFares(); });

  • android app doesn't show on the emulator

    - by Anna Finela Constantino
    I made an android application using eclipse and it is working fine when I started developing my app. But then as I continue to develop the app the emulator seems to be not updating the application prior to the changes I have made on the code. So I tried deleting my avd and create a new one every time I run my app, and that seems to have worked. Now my problem is that my emulator doesn't show my app. It says "Failed to install *.apk on device 'emulator-5554': An established connection was aborted by the software in your host machine". I searched for ways to solved it but none of it seems to have worked. I tried killing the adb process (as most my searches would say) on the task manager but still my app doesn't show on the emulator. The emulator is running and all but my icon is nowhere to be found. Am I misssing out something? Is the problem connected to the first problem i had before? As I said, I started developing android app recently, so please bear with me. :) I appreciate all your help.Thanks in advance.

  • How to make sure an action completes before you continue

    - by HurkNburkS
    I am trying to close a UIView thats in one method from another method by calling it, The UIView closes fine but not untill after all of the processes are finished in the current method. I would like to know if there is a way to force the first thing to happen first (i.e. close UIviews) then continue the current method? This is what my method looks like - (void)selectDeselectAllPressed:(UIButton*)button { int id = button.tag; [SVProgressHUD showWithStatus:@"Updating" maskType:SVProgressHUDMaskTypeGradient]; [self displaySelected]; // removes current view so you can load hud will not be behind it if (id == 1) { [self selectAllD]; } else if (id == 2) { [self deselectAllD]; } else if (id == 3) { [self selectAllI]; } else if (id == 4) { [self deselectAllI]; } } as you can see what happens is this method is called when a button is pressed, I would like for the displaySelected method to do what it needs to do before any of the other methods are called? Currently what happes when i debug this is displaySelected method is called the thread walks through that then continues to the if statment then after the method in the if statment has finished then displaySelected changes are made... its so weird. any help would be greatly appreciated.

  • Disable a form and all contained elements until an ajax query completes (or another solution to prev

    - by Max Williams
    I have a search form with inputs and selects, and when any input/select is changed i run some js and then make an ajax query with jquery. I want to stop the user from making further changes to the form while the request is in progress, as at the moment they can initiate several remote searches at once, effectively causing a race between the different searches. It seems like the best solution to this is to prevent the user from interacting with the form while waiting for the request to come back. At the moment i'm doing this in the dumbest way possible by hiding the form before making the ajax query and then showing it again on success/error. This solves the problem but looks horrible and isn't really acceptable. Is there another, better way to prevent interaction with the form? To make things more complicated, to allow nice-looking selects, the user actually interacts with spans which have js hooked up to them to tie them to the actual, hidden, selects. So, even though the spans aren't inputs, they are contained in the form and represent the actual interactive elements of the form. Grateful for any advice - max. Here's what i'm doing now: function submitQuestionSearchForm(){ //bunch of irrelevant stuff var questionSearchForm = jQuery("#searchForm"); questionSearchForm.addClass("searching"); jQuery.ajax({ async: true, data: jQuery.param(questionSearchForm.serializeArray()), dataType: 'script', type: 'get', url: "/questions", success: function(msg){ //more irrelevant stuff questionSearchForm.removeClass("searching"); }, error: function(msg){ questionSearchForm.removeClass("searching"); } }); return true; }

  • R from java with no graphics: is it worth moving to JRI

    - by LH
    I have a system set up that's been happily running R from a java servlet, spawning processed & hooking into the process's stdin, stdout, and stderr streams, as in the second andwer to this question. After a system upgrade (that included glibc), the input is no longer reaching the R process.* Until now, 'R --vanilla --slave -f [file] ...' was working fine for me. I also have no swing dependencies right now, so I'm somewhat reluctant to add them. (I may actually not be able to add swing dependencies; am I right that using REngine automatically brings swing in? The examples import all of swing.) Are there advantages to switching to JRI? What changes would I need to make to my R script? (It currently reads from stdin and writes to stdout). I'm not finding the provided examples terribly helpful for how to use JRI in this situation. Thanks for your help & comments. *I can't even tell if the problem is data being written too soon or too late, but that's a separate issue/question; if I move to JRI I'm hoping it all becomes moot.

  • C# Custom user settings class not saving

    - by Zenox
    I have the following class: [Serializable] [XmlRoot ( ElementName = "TextData", IsNullable = false)] public class TextData { private System.Drawing.Font fontColor; [XmlAttribute ( AttributeName = "Font" )] public System.Drawing.Font Font { get; set; } [XmlAttribute ( AttributeName = "FontColor" )] public System.Drawing.Color FontColor { get; set; } [XmlAttribute ( AttributeName = "Text" )] public string Text { get; set; } public TextData ( ) { } // End of TextData } // End of TextData And Im attempting to save it with the following code: // Create our font dialog FontDialog fontDialog = new FontDialog ( ); fontDialog.ShowColor = true; // Display the dialog and check for an ok if ( DialogResult.OK == fontDialog.ShowDialog ( ) ) { // Save our changes for the font settings if ( null == Properties.Settings.Default.MainHeadlineTextData ) { Properties.Settings.Default.MainHeadlineTextData = new TextData ( ); } Properties.Settings.Default.MainHeadlineTextData.Font = fontDialog.Font; Properties.Settings.Default.MainHeadlineTextData.FontColor = fontDialog.Color; Properties.Settings.Default.Save ( ); } Everytime I load the the application, the Properties.Settings.Default.MainHeadlineTextData is still null. Saving does not seem to take effect. I read on another post that the class must be public and it is. Any ideas why this would not be working properly?

  • '<=' operator is not working in sql server 2000

    - by Lalit
    Hello, Scenario is, database is in the maintenance phase. this database is not developed by ours developer. it is an existing database developed by the 'xyz' company in sql server 2000. This is real time database, where i am working now. I wanted to write the stored procedure which will retrieve me the records From date1 to date 2.so query is : Select * from MyTableName Where colDate>= '3-May-2010' and colDate<= '5-Oct-2010' and colName='xyzName' whereas my understanding I must get data including upper bound date as well as lower bound date. but somehow I am getting records from '3-May-2010' (which is fine but) to '10-Oct-2010' As i observe in table design , for ColDate, developer had used 'varchar' to store the date. i know this is wrong remedy by them. so in my stored procedure I have also used varchar parameters as @FromDate1 and @ToDate to get inputs for SP. this is giving me result which i have explained. i tried to take the parameter type as 'Datetime' but it is showing error while saving/altering the stored procedure that "@FromDate1 has invalid datatype", same for "@ToDate". situation is that, I can not change the table design at all. what i have to do here ? i know we can use user defined table in sql server 2008 , but there is version sql server 2000. which does not support the same. Please guide me for this scenario. **Edited** I am trying to write like this SP: CREATE PROCEDURE USP_Data (@Location varchar(100), @FromDate DATETIME, @ToDate DATETIME) AS SELECT * FROM dbo.TableName Where CAST(Dt AS DATETIME) >=@fromDate and CAST(Dt AS DATETIME)<=@ToDate and Location=@Location GO but getting Error: Arithmetic overflow error converting expression to data type datetime. in sql server 2000 What should be that ? is i am wrong some where ? also (202 row(s) affected) is changes every time in circular manner means first time sayin (122 row(s) affected) run again saying (80 row(s) affected) if again (202 row(s) affected) if again (122 row(s) affected) I can not understand what is going on ?

  • Ways to prevent multiple email notification with php&mysql

    - by Louis Loudog Trottier
    My 1st post, but i got many great answers and tips from stackoverflow so far. This one was a close call- How does facebook, gmail send the real time notification? but not exactly, so let brainstorm this together. I have CMS system with mail notification when a change is made on the site. Everything wotk very well but i want to prevent multiple notification if somene make another quick change to, let say, fix a typo. Using php mail(), obviously. I've tough of 2 ways, one simple, and one.... let just say, pretty heavy... cough. the 3rd one was inspired by Implementing Email Notification but really doesn't look appealing to me to send bunch of email at once. Use a timestamp to check if another change was made in the 'let say' last 5 minutes. Record the last change, and compare it to the new one. Could be usefull for backup at the same time since i'll have to save the change somewhere, but text can be long and making an sql search would be painfull. Wouldn't it? Use cron to send changes every x minutes... convince me if you ythink it is a suitable solution. Any ideas, comment or suggestion of your own? Looking forward for your inputs, and since i now registered, i'll do my best to help around. Cheers, all llt

  • Update table with index is too slow

    - by pauloya
    Hi, I was watching the Profiler on a live system of our application and I saw that there was an update instruction that we run periodically (every second) that was quite slow. It took around 400ms every time. The query includes this update (which is the slow part) UPDATE BufferTable SET LrbCount = LrbCount + 1, LrbUpdated = getdate() WHERE LrbId = @LrbId This is the table CREATE TABLE BufferTable( LrbId [bigint] IDENTITY(1,1) NOT NULL, ... LrbInserted [datetime] NOT NULL, LrbProcessed [bit] NOT NULL, LrbUpdated [datetime] NOT NULL, LrbCount [tinyint] NOT NULL, ) The table has 2 indexes (non unique and non clustered) with the fields by this order: * Index1 - (LrbProcessed, LrbCount) * Index2 - (LrbInserted, LrbCount, LrbProcessed) When I looked at this I thought that the problem would come from Index1 since LrbCount is changing a lot and it changes the order of the data in the index. But after desactivating index1 I saw the query was taking the same time as initially. Then I rebuilt index1 and desactivated index2, this time the query was very fast. It seems to me that Index2 should be faster to update, the order of the data shouldn't change since the LrbInserted time is not changed. Can someone explain why index2 is much heavier to update then index1? Thank you!

  • Mystery: How does Google do cross-domain iframe communication?

    - by Shraga
    Hi everyone, When you host Googles web search element on a page, a div is created which incorporates an iframe which points to a Google adsense ads page. However, if there are no ads for the specific query, Google somehow changes the class on YOUR domain to render the div (and iframe) invisible. They are NOT using postMessage, as it also works in IE7. They are also not using the fragment identifier method, as no hash appears in the url. So how do they do it? To check what I'm saying just put the following into a regular html page: <!-- Google Custom Search Element --> <div id="cse" style="width:100%;">Loading</div> <script src="http://www.google.com/jsapi" type="text/javascript"></script> <script type="text/javascript"> google.load('search', '1'); google.setOnLoadCallback(function(){ new google.search.CustomSearchControl().draw('cse'); }, true); </script> and then do a search for "cars" (or anything else that will definitely have ads) and then for "wzxv", which has no ads...

  • Looking for an email/report templating engine with database backend - for end-users ...

    - by RizwanK
    We have a number of customers that we have to send monthly invoices too. Right now, I'm managing a codebase that does SQL queries against our customer database and billing database and places that data into emails - and sends it. I grow weary of maintaining this every time we want to include a new promotion or change our customer service phone numbers. So, I'm looking for a replacement to move more of this into the hands of those requesting the changes. In my ideal world, I need : A WYSIWYG (man, does anyone even say that anymore?) email editor that generates templates based upon the output from a Database Query. The ability to drag and drop various fields from the database query into the email template. Display of sample email results with the database query. Web application, preferably not requiring IIS. Involve as little code as possible for the end-user, but allow basic functionality (i.e. arrays/for loops) Either comes with it's own email delivery engine, or writes output in a way that I can easily write a Python script to deliver the email. Support for generic Database Connectors. (I need MSSQL and MySQL) F/OSS So ... can anyone suggest a project like this, or some tools that'd be useful for rolling my own? (My current alternative idea is using something like ERB or Tenjin, having them write the code, but not having live-preview for the editor would suck...)

  • jQuery Toggle switch images

    - by Sixfoot Studio
    Hi Guys, I have a situation where I am not understanding jQuery's Toggle. I have two buttons, both of them open the same content and when you click on either button the content should open or close and the attribute changes the button from open to closed. (So both buttons do the same function). Only thing is, when I click on the top button and it opens my content and then click on the lower button to close it, the image attributes are switched incorrectly. Here's a very stripped down version of what my code looks like and I would appreciate some help. <script language="javascript" type="text/javascript"> $(function () { var open = false; $("#button1, #button2").toggle( function () { open = true; $("#button1").attr("src", "images/btn-open.gif"); $("#button2").attr("src", "images/btn-open.gif"); }, function () { if (open) { $("#button1").attr("src", "images/btn-closed.gif"); $("#button2").attr("src", "images/btn-closed.gif"); } else { $("#button1").attr("src", "images/btn-open.gif"); $("#button2").attr("src", "images/btn-open.gif"); } open = false; } ); }); </script> <img id="button1" src="images/btn-open.gif"></img> <br /> <br /> <br /> <br /> <img id="button2" src="images/btn-open.gif"></img>

  • C++ - Totally suspend windows application

    - by HardCoder1986
    Hello! I am developing a simple WinAPI application and started from writing my own assertion system. I have a macro defined like ASSERT(X) which would make pretty the same thing as assert(X) does, but with more information, more options and etc. At some moment (when that assertion system was already running and working) I realized there is a problem. Suppose I wrote a code that does some action using a timer and (just a simple example) this action is done while handling WM_TIMER message. And now, the situation changes the way that this code starts throwing an assert. This assert message would be shown every TIMER_RESOLUTION milliseconds and would simply flood the screen. Options for solving this situation could be: 1) Totally pause application running (probably also, suspend all threads) when the assertion messagebox is shown and continue running after it is closed 2) Make a static counter for the shown asserts and don't show asserts when one of them is already showing (but this doesn't pause application) 3) Group similiar asserts and show only one for each assert type (but this also doesn't pause application) 4) Modify the application code (for example, Get / Translate / Dispatch message loop) so that it suspends itself when there are any asserts. This is good, but not universal and looks like a hack. To my mind, option number 1 is the best. But I don't know any way how this can be achieved. What I'm seeking for is a way to pause the runtime (something similiar to Pause button in the debugger). Does somebody know how to achieve this? Also, if somebody knows an efficient way to handle this problem - I would appreciate your help. Thank you.

  • Use a table as container or not?

    - by Camran
    I have created my entire website by using a main table, and having the content inside the table. Some ppl suggest this is wrong, and I would like to know what to do specifically in my situation. On my index.html I have a <table align="center"> and then all content in it. Now the content is in form of DIVS and they all have relative positioning, so they are relative to the table. For example: <table align="center"> <tr> <td> <div style="position:relative; left:14px; top:50px;"> CONTENT HERE... (Form, divs, images) </div> </td> </tr> </table> I have just gotten to the stage of browser compatibility. Without making any changes whatsoever, my website works perfect in FF, SAFARI, Chrome and Opera. Only trouble with IE. So for my Q, if you where me, would you change my layout and remove the tables, and instead use alot more css and alot more DIVS, or would you go with what I have? And please if you answer me, don't just provide me with the answer, but also a "why" that is... in other words, give me arguments and facts... Thanks

  • Real time content editing html5

    - by Mark Lauzon
    So I've seen things like WordPress and FCKEditor, and basically a bunch of stuff that uses external code that I can't see or edit. Whenever I ask about editing and saving the content of a page in real time I just get referenced to an API or I get handed code that only changes the page until it's reloaded. What I want to know is how do I code it myself? I want to add real time content editing to a page without the use of someone else's code. I've checked out code for various forums and wikipedia and whatnot, and all of it references code I don't have access to. Is this a thing? Can I edit a page in real time? I thought of writing the edited text to a file on the server, and then when they click save, reading it back into the code to the section they were editing, but I don't know how to do that or if it's even possible. As a side note, I'm very new to html, but not new to coding. EDIT: The structure can be very much like Wikipedia, it doesn't have to be real time, it just has to work

  • Timer not beginning from 00:00

    - by studentProgrammer
    I have a Game in which there is a timer involved. For each two minutes that passes a new round between different players begins. So, I have a text box starting from 00:00 and changes each second until it is equal to 02:00. Now, I want to save the state of the game in the middle of a round if the user closes the form. What I need to do is that upon loading, the textbox starts at the time that the user left the game the last time and continue up till 02:00 normally. How can I do this? This is what I have until now where Tournament is the Form public Tournament() { _timer = new System.Windows.Forms.Timer(); _timer.Interval = 1000; _timer.Tick += Timer_Tick; _myDateTime = DateTime.Now; newDate = new DateTime(); newDate = newDate.AddMinutes(2.00); _timer.Start(); InitializeComponent(); } void Timer_Tick(object sender, EventArgs e) { var diff = DateTime.Now.Subtract(_myDateTime); this.textBox1.Text = diff.ToString(@"mm\:ss"); DateTime dt = Convert.ToDateTime(diff.ToString()); if (newDate.Minute == dt.Minute) { _timer.Stop(); _myDateTime = DateTime.Now; displayPointsOrResults(); this.textBox1.Text = diff.ToString(@"mm\:ss"); } } In my LoadGame method: where timePassed is what I have written in the text box string[] splitted6 = timePassed.Split(':'); if (splitted6[0] == "00") { int remainingTime = 120 - Convert.ToInt32(splitted6[1]); DateTime time = DateTime.Now.Date; time = time.AddMinutes(remainingTime); _myDateTime = time; } else { int leftTime = Convert.ToInt32(splitted[0].Trim('0') + splitted[1]); int remainingTime = 120 - leftTime; DateTime time = DateTime.Now.Date; time = time.AddMinutes(remainingTime); _myDateTime = time; }

  • Hibernate 1:M relationship ,row order, constant values table and concurrency

    - by EugeneP
    table A and B need to have 1:M relationship a and b are added during application runtime, so A created, then say 4 B's created. Each B instance has to come in order, so that I could later extract them in the same order as I added them. The app will be a web-app running on Tomcat, so 10 instances may work simultaneously. So my question are: 1) How to preserve inserting order, so that I could extract B instances that A references in the same order as I persisted them. That's tricky, because we add to a Collection and then it gets saved (am I right?). So, it depends on how Hibernate saves it, what if it changes the order in what we added instances? I've seen something like LIST instead of SET when describing relationships, is that what I need? 2) How to add a 3-rd column to B so that I could differentiate the instances, something like SEX(M,F,U) in B table. Do I need a special table, or there's and easy way to describe constants in Hibernate. What do you recommend? 3) Talking about concurrency, what methods do you recommend to use? There should be no collisions in the db and as you see, there might easily be some if rows are not inserted (PK added) right where it is invoked without delays ?

  • Creating 3rd party library in Android. Need suggestions!!

    - by Lalith
    Hello all, I am planning to create a 3rd party library for android application developers. Also the main concern is I do not want the users to make many changes to their code base. The following are the main things I want to clarify before diving into the project. 1) I want to attach my own event handlers dynamically to the application. As per above limitations I mentioned, I cannot make users put the relevant code in their handlers as I need to support existing applications as well. I found out that we cannot attach more than one event handler per one listener. For example Button.setOnclickListener(somelistener) .. will set one listener. In traditional desktop applications we can add more than one handlers but here if I do one more Button.setOnclickListener(someOtherListener) this one overwrites the previous listener. Is there any way I can attach my own listener along with application's existing listeners dynamically? Also is it really not supported on android yet? 2) Is there any 3rd party alternative that exists already that monitors user's interactions in androidi? 3) If this is not supported now are there any future plans to support this feature? Please let me know about this as I did not get much feedback on Stackoverflow. Any suggestions and workarounds would really help me continue with this project. Regards, Lalith

  • Do Distributed Version Control Systems promote poor backup habits?

    - by John
    In a DVCS, each developer has an entire repository on their workstation, to which they can commit all their changes. Then they can merge their repo with someone else's, or clone it, or whatever (as I understand it, I'm not a DVCS user). To me that flags a side-effect, of being more vulnerable to forgetting to backup. In a traditional centralised system, both you as a developer and the people in charge know that if you commit something, it's held on a central server which can have decent backup solutions in place. But using a DVCS, it seems you only have to push your work to a server when you feel like sharing it. It's all very well you have the repo locally so you can work on your feature branch for a month without bothering anyone, but it means (I think) that checking in your code to the repo is not enough, you have to remember to do regular pushes to a backed-up server. It also means, doesn't it, that a team lead can't see all those nice SVN commit emails to keep a rough idea what's going on in the code-base? Is any of this a real issue?

  • Clarification on ZVals

    - by Beachhouse
    I was reading this: http://www.dereleased.com/2011/04/27/the-importance-of-zvals-and-circular-references/ And there's an example that lost me a bit. $foo = &$bar; $bar = &$foo; $baz = 'baz'; $foo = &$baz; var_dump($foo, $bar); /* string(3) "baz" NULL */ If you’ve been following along, this should make perfect sense. $foo is created, and pointed at a ZVal location identified by $bar; when $bar is created, it points at the same place $foo was pointed. That location, of course, is null. When $foo is reassigned, the only thing that changes is to which ZVal $foo points; if we had assigned a different value to $foo first, then $bar would still retain that value. I learned to program in C. I understand that PHP is different and it uses ZVals instead of memory locations as references. But when you run this code: $foo = &$bar; $bar = &$foo; It seems to me that there would be two ZVals. In C there would be two memory locations (and the values would be of the opposite memory location). Can someone explain?

  • EventHandlers saved to databases.

    - by Stacey
    In a database application (using Sql Server right now, in C#, with Entity Framework 4.0) I have a situation where I need to trigger events when some values change. For instance assume a class "Trackable". class Trackable { string Name { get; set; } int Positive { get; set; } int Negative { get; set; } int Total { get; set; } // event OnChanged } Trackable is represented in the database as follows; table Trackables Id | guid name | varchar(32) positive | int negative | int Total is of course, calculated at runtime. When a trackable event changes, I want to inspect its previous value, and then see what it is changing to, and be capable of reacting accordingly. However different trackables need to trigger different events (to avoid a huge, massive cascading switch/if block). If this were just only C# code it would be easy - but they have to be saved to the database. I can't divide up each different trackable into a different table/class, that would be silly - they are all identical, but the event raised is different based on how they are made. So I guess my question is, is there any way to store an event handler in a database such that..

  • Using jQuery .find() with multiple conditions at the same time?

    - by fuzzybabybunny
    I know that there are other ways of grabbing radio button values, but I want to know how to do this with .find(). I only want to log the value of the selected radio button, so it requires finding by two conditions at the same time: The button with name=area The button with selected=selected <div class="radio"> <label> <input class="track-order-change" type="radio" name="area" id="area1" value="area1" checked="checked"> Area 1 </label> </div> <div class="radio"> <label> <input class="track-order-change" type="radio" name="area" id="area2" value="area2"> Area 2 </label> </div> <div class="radio"> <label> <input class="track-order-change" type="radio" name="area" id="area3" value="area3"> Area 3 </label> </div> When anything with the class track-order-change changes, it will run the function UpdateOrderSubmission. $('.track-order-change').on('change', function() { updateOrderSubmission() }); I want the updateOrderSubmission function to console log the value of the radio button that is selected. var updateOrderSubmission = function() { var orderSubmission = { area: $('#submit-initial-form').find('[name=area],[checked=checked]').this.val() } console.log(orderSubmission) }; The code above doesn't work. How do I grab the value of the selected radio button? I need to do .find() with two conditions (name and checked), not just one condition.

  • Using Gtk.TreeDragSource.drag_data_get()

    - by knutsondc
    I have a simple Gtk.TreeView with a Gtk.ListStore with four columns as the model. I want to be able to drag and drop rows within the TreeView and track row insertions, changes and deletions as they happen so I can implement undo/redo to drag and drop operations. I'm using PyGObject 3 and Python 3.2. I thought that using methods under the Gtk.TreeDragSource and Gtk.TreeDragDest interfaces would suit my needs perfectly, with Gtk.TreeDragSource.drag_data_get() in my drag_data_get handler and Gtk.TreeDragDest.drag_data_received() or Gtk.tree_get_row_drag_data() in my drag_data_received handler. Basically, what I've tried looks something like this: def drag_data_received(self, treeview, context, x, y, selection, info, time): treeselection = tv.get_selection() model, my_iter = treeselection.get_selected() path = model.get_path(my_iter) result = Gtk.TreeDragSource.drag_data_get(path, selection) def drag_data_received(self, tv, context, x, y, selection, info, time): result, model, row = Gtk.tree_get_row_drag_data(selection) my_iter = model.get_iter(row) data = [model.get_value(my_iter, i) for i in range(model.get_n_columns())] drop_info = tv.get_dest_row_at_pos(x, y) if drop_info: path, position = drop_info my_iter = model.get_iter(path) if (position == Gtk.TreeViewDropPosition.BEFORE or position == Gtk.TreeViewDropPosition.INTO_OR_BEFORE): model.insert_before(my_iter, [data]) else: model.insert_after(my_iter, [data]) else: model.append([data]) if context.get_actions() == Gdk.DragAction.MOVE|Gdk.DragAction.DEFAULT: context.finish(True, True, time) return This fails spectacularly - when Python hits the call to Gtk.TreeDragSource.drag_data_get(), Python crashes and my program window swiftly disappears. I don't even get to the drag_data_received handler. Can anyone point me to some example code showing how these methods using the TreeDragSource and TreeDragDest interfaces work? Any help much appreciated!
