  • Putting cursor into dynamically added input fields with jQuery

    - by Sandoichi
    I wrote a script that allows users to click onto a table cell and edit the value with jQuery. Basically, when they click the cell, the HTML in the cell gets replaced with an input box and any text that was previously in the cell gets added to the input. My issue is that whenever they click on the cell, the input doesn't get focused and they have to click a second time to put the cursor in. I have tried a bunch of selectors with .focus() to try and put the cursor in but I'm not having any luck. Here is the function that gets called when the user clicks on a cell: function edit_cell() { if($(this).hasClass('edit_box')) if(!$(this).hasClass('editable')){ $(this).addClass('editable'); string = $(this).text(); $(this).html("<input type='text' value='" + string + "'/>"); } } Also, is there a way to make the size of the input box relative to the width of the cell it gets added too? I don't know how to relate the size attribute to the width for the cell...and it is driving me crazy!

  • Can a Mediawiki table be dynamically created using other Mediawiki pages?

    - by Ashimema
    OK, So I've got created a page on my wiki which contains just a single table listing various details about servers and customers. You can follow links for each customer name in the table to find additional details about said customer. What I want to know is; Can the information in the customers page (page B) be used to dynamically update the table (Page A). Is this something that the Semantic MediaWiki extension can accomplished? Running Mediawiki 1.16.2

  • How can I dynamically load the correct sprite from a sprite sheet?

    - by Leonard Challis
    I am making a simple card game in unity. The game is based on a standard 52-card pack, with identical backs for unique faces. In my particular game different cards are worth different values and have various special abilities. The game will have 52 cards on the table (on the draw position or in the face-down deck or in someone's hand) at all times, so this number won't change. I thought that making a Card prefab and instantiating 52 of these manually would be a bad idea. Even doing it in code, I thought, would be a bit OTT, and that I should just instantiate visual cards when they are face-up to the player. I have a sprite sheet of the 52 cards and the back, which is imported as a Sprite in multiple mode, sliced in to a grid containing all the cards needed to play the game. The problem I now face is that, through my GameController script I want to generate a shuffled pack of cards, deal some to each player and then show those cards to a player. However, I am not sure of the best way, or even if it's possible, to do this dynamically with the sprite sheets as they are. For instance if I have the following: private CardRank rank; private CardSuite suite; private void Start() { this.rank = CardRank.Ace; this.suite = CardSuite.Spades; } This class would be instantiated by the game manager. I would have 52 of these in code. Whenever I have to visually show a card in the scene, I would use a card prefab, which is essentially a game object with a SpriteRenderer on it. I would need to dynamically load the correct sprite for this object from the spritesheet. The sliced sprites from the sprite sheet actually have names in the format AS (Ace of Spades), 7H (Seven of Hearts), etc - though this was a manual thing I did myself of course. I have also tried various alternative solutions, including creating animations, having separate sprites not in a spritesheet and having an array of available sprites in an array with a specific index for each card, but none seem as elegant as trying to load the correct sprite at runtime, as I'm trying to. So, how do I load a specific sprite from a spritesheet at runtime? I'm open to suggestions, even those that make me think differently about how to approach the problem.

  • Am I permitted to use an LGPL library without releasing the source to the rest of my application, if I dynamically reference the library?

    - by user185812
    I am a bit confused as to what I am/am not allowed to do with a LGPL Library that I intend on using in a small scale commercial C++ Application that I am developing. My current understanding, although I don't know if I am correct, is that I am permitted use the library without releasing the source to the rest of my application if I dynamically reference the library. Does anyone know if this is correct? Are there any restrictions as to how I reference the library? Thank You! I am not a native English speaker and don't understand the licence entirely.

  • Best way to trigger editing and dynamically show editing features? [on hold]

    - by Tim Marshall
    Page In Question: http://rafflebananza.com/admin/StatisticalData/expenses/expenses.html Hiya Everyone, On my page, I have an 'Actions' drop down to the top-right hand side of the page. This actions drop down I would like to have an action to 'Enable Editing'. Upon clicking to enable editing, I would like a PHP variable modified from 'EnableEditing = false' to 'EnableEditing = true'. Why I would like to use PHP maybe questionable, here is why I would like to use PHP under my understanding to clarify; Sections on my page will show to different administrators depending on their level. Upon enabling editing mode, certain contents will then dynamically. <?php if ($_SESSION['user_level_status'] < 2) { if ($editing = enabled) { show this } else { show this } } ?> Something similar to this, I'm new at PHP so this may look incorrect. The question really is, is PHP the correct language to use to trigger editing and how can I do this please? Best Regards, Tim

  • How to display the dynamically created elements for some time?

    - by Holicreature
    i have some rows of data displayed in a table and on mouse over of each row i've list two buttons inside a div element and then display it for some time. And i've associated some functions to be called on clicking the buttons that are dynamically created and displayed elements.. So what i did was i wrote a function which will create elements dynamically and place them exactly where i wanted using styles. And i wrote another function which will remove these dynamically added elements. I called them on mouseover and mouseout events of the row. now when i move mouse out the row to click the button they get disappeared bcoz of my mouseout function. So how can i proceed this? And what is the perfect method to create these kind of stuffs?

  • Flex AS3: Assign a button's upSkin property with a remote file dynamically?

    - by aaron.lovelace
    I am building a Flex application with ActionScript 3. Unfortunately I've hit a wall with this one... I would like to be able to apply an upSkin to my dynamically generated button like this: //this theSkin variable is dynamic in my app, but for this example it's a simple string var theSkin:String = "http://www.mypicturedomain.com/images/myimage.gif"; var navBtn:Button = new Button(); navBtn.id = "thumb1"; navBtn.width = 60; navBtn.height = 45; //skin the button navBtn.setStyle("upSkin", theSkin); //add the button to my canvas myCanvas.addChild(navBtn); When I attempt this, I get this error: TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Loader@3dac941 to Class. How do I skin this button with my image dynamically? A couple of things to consider: The upSkin image must be remote. It can't be local. The button must be generated dynamically (it's in a for loop). Any help/ideas would be much appreciated at this point!

  • Which data structure should I use for dynamically generated platforms?

    - by Joey Green
    I'm creating a platform type of game with various types of platforms. Platforms that move, shake, rotate, etc. Multiple types and multiple of each type can be on the screen at once. The platforms will be procedural generated. I'm trying to figure out which of the following would be a better platform system: Pre-allocate all platforms when the scene loads, storing each platform type into different platform type arrays( i.e. regPlatformArray ), and just getting one when I need one. The other option is to allocate and load what I need when my code needs it. The problem with 1 is keeping up with the indices that are in use on screen and which aren't. The problem with 2 is I'm having a hard time wrapping my head around how I would store these platforms so that I can call the update/draw methods on them and managing that data structure that holds them. The data structure would constantly be growing and shrinking. It seems there could be too much complexity. I'm using the cocos2d iPhone game engine. Anyways, which option would be best or is there a better option?

  • How do I inject test objects when the real objects are created dynamically?

    - by JW01
    I want to make a class testable using dependency injection. But the class creates multiple objects at runtime, and passes different values to their constructor. Here's a simplified example: public abstract class Validator { private ErrorList errors; public abstract void validate(); public void addError(String text) { errors.add( new ValidationError(text)); } public int getNumErrors() { return errors.count() } } public class AgeValidator extends Validator { public void validate() { addError("first name invalid"); addError("last name invalid"); } } (There are many other subclasses of Validator.) What's the best way to change this, so I can inject a fake object instead of ValidationError? I can create an AbstractValidationErrorFactory, and inject the factory instead. This would work, but it seems like I'll end up creating tons of little factories and factory interfaces, for every dependency of this sort. Is there a better way?

  • How can I host a website on a dynamically-assigned IP address?

    - by nick
    I recently upgraded my internet to the point that it is much faster and more reliable than my current webhost. I would like to move my current domain to be hosted at home, but my IP address is dynamic. As far as I know, I only get a new IP when I restart my modem and or router (which is almost never) or when cable one (my ISP) pushes out a firmware update (rarely). There are a few ways I can see doing this: Convince my ISP to give me a static IP Assign my router my current IP to force a static IP (which might work?) Set my DNS record to my current IP address and update it on the rare occasions that it changes. Obviously I'm hoping that the first one works, but I don't want to pay a lot of extra money (if that's what it takes) to get a static IP address. Which of these options will work most reliably?

  • Can static and dynamically typed languages be seen as different tools for different types of jobs?

    - by Erik Reppen
    Yes, similar questions have been asked but always with the aim of finding out 'which one is better.' I'm asking because I came up as a dev primarily in JavaScript and don't really have any extensive experience writing in statically typed languages. In spite of this I definitely see value in learning C for handling demanding operations at lower levels of code (which I assume has a lot to do with static vs dynamic at the compiler level), but what I'm trying to wrap my head around is whether there are specific project contexts (maybe certain types of dynamic data-intensive operations?) involving things other than performance where it makes a lot more sense to go with Java or C# vs. something like Python.

  • Algorithm for dynamically calculating a level based on experience points?

    - by George
    One of the struggles I've always had in game development is deciding how to implement experience points attributed to gaining a level. There doesn't seem to be a pattern to gaining a level in many of the games I've played, so I assume they have a static dictionary table which contains experience points vs. the level. e.g. Experience Level 0 1 100 2 175 3 280 4 800 5 ...There isn't a rhyme or reason why 280 points is equal to level 4, it just is. I'm not sure how those levels are decided, but it certainly wouldn't be dynamic. I've also thought about the possibility of exponential levels, as not to have to keep a separate lookup table, e.g. Experience Level 0 1 100 2 200 3 400 4 800 5 1600 6 3200 7 6400 8 ...but that seems like it would grow out of control rather quickly, as towards the upper levels, the enemies in the game would have to provide a whopping amount of experience to level -- and that would be to difficult to control. Leveling would become an impossible task. Does anyone have any pointers, or methods they use to decide how to level a character based on experience? I want to be fair in leveling and I want to stay ahead of the players as not to worry about constantly adding new experience/level lookups.

  • Dynamically rewrite URLs upon the user's selection - is it possible?

    - by jitzo
    In my PHP based web application, there's a form that generates a URL according to the user's selection. The form has 7 different fields, each one of them affects the final URL, none of them is mandatory. The final URL can be: /field1/user_setting_of_field1/field3/user_setting_of_field3/field6/user_setting_of_field6/ or just: /field4/user_setting_of_field4 these URLs should be rewritten to- /results.php?field1=user_setting_of_field1&field3=user_setting_of_field3&field6=user_setting_of_field6 and: /results.php?field4=user_setting_of_field4 Is it possible to create a single rewrite rule that will cover these variations? I'd hate to create different rewrite rule for every possible scenario, it'll take forever... I'm currently developing the app on a Windows machine with IIS 7.5, but will eventually deploy it to an Apache server. Is it possible in both? I currently need to solve it for the IIS environment, and later on for Apache.

  • Is it a good idea to dynamically position and size controls on a form or statically set them?

    - by CrystalBlue
    I've worked mostly with interface building tools such as xCode's Interface Builder and Visual Studio's environment to place forms and position them on screens. But I'm finding that with my latest project, placing controls on the form through a graphical interface is not going to work. This more has to do with the number of custom controls I have to create that I can't visually see before hand. When I first tackled this, I began to position all of my controls relative to the last ones that I created. Doing this had its own pros and cons. On the one hand, this gave me the opportunity to set one number (a margin for example) and when I changed the margin, the controls all sized correctly to one another (such as shortening controls in the center while keeping controls next to the margin the same). But this started to become a spiders-web of code that I knew wouldn't go very far before getting dangerous. Change one number and everything re sizes, but remove one control and you've created many more errors and size problems for all the other controls. It became more surgery then small changes to controls and layout. Is there a good way or maybe a preferred way to determine when I should be using relative or absolute positioning in forms?

  • Dynamically change the width of Datagrid column in FLEX.

    - by user120118
    Hi, Can we change the width of the datagrid column dynamically by clicking on the border of the column in order to display the complete string which is too long to be displayed and needs to be scrolled ? If so, How ? Also, how can we ensure that the column width changes dynamically based on the number of characters / length of string; since many a times the data is too long to be displayed. Can we set the column width to take the length of data into consideration before displaying onto the datagrid ?

  • How to enlarge dynamically an UILabel (label and font size)?

    - by Flocked
    Hello, Im currently working on an iPhone project. I want to enlarge dynamically an UILabel in Objective-C like this: How is this possible? I thought I have to do it with CoreAnimation, but I didn't worked. Here is the code I tried: UILabel * fooL = //[…] fooL.frame = CGRectMake(fooL.frame.origin.x, fooL.frame.origin.y, fooL.frame.size.width, fooL.frame.size.height); fooL.font = [UIFont fontWithName:@"Helvetica" size:80]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationCurve:UIViewAnimationCurveEaseIn]; [UIView setAnimationDelegate:self]; [UIView setAnimationDuration:0.5]; [UIView setAnimationBeginsFromCurrentState:YES]; fooL.font = [UIFont fontWithName:@"Helvetica" size:144]; //bigger size fooL.frame = CGRectMake(20 , 44, 728, 167); //bigger frame [UIView commitAnimations]; The problem with this code is that it doesn't change the fontsize dynamically.

  • Are there any real benefits to including javascript dynamically rather than as script tags at the bo

    - by SB
    I've read that including the scripts dynamically may provide some better performance, however i'm not really seeing that on the small local tests I'm doing. I created a jquery plugin to dynamically load other plugins as necessary and am curious as to if this is actually a good idea. The following would be called onready or at the bottom of the page(I can provide the source for the plugin if anyone is interested): $.fn.executePlugin( 'qtip', // looks in default folder { required: '/javascript/plugin/easing.js', // not really required for qtip just testing it version: 1, //used for versioning and caching checkelement: '#thumbnail', // will not include plugin if $(element).length==0 css: 'page.css', // include this css file as well with plugin cache:true, // $.ajax will use cache:true success:function() { // success function to be called after the plugin loads - apply qtip to an element $('#thumbnail').qtip( { content: 'Some basic content for the tooltip', // Give it some content, in this case a simple string style: {name:'cream'}, }); } });

  • Would Apache running on port 8080 prevent dynamically loaded scripts in JavaScript?

    - by editor
    Had a nice PHP/HTML/JS prototype working on my personal Linode, then tried to throw it into a work machine. The page adds a script tag dynamically with some JavaScript. It's a bunch of Google charts that update based on different timeslices. That code looks something like this: // jQuery $.post to send the beginning and end timestamps $.post("channel_functions.php", data_to_post, function(data){ // the data that's returned is the javascript I want to load var script = document.createElement('script'); var head= document.getElementsByTagName('head')[0]; var script= document.createElement('script'); var text = document.createTextNode(data); script.type= 'text/javascript'; script.id = 'chart_data'; script.appendChild(text); // Adding script tag to page head.appendChild(script); // Call the function I know were present in the script tag loadTheCharts(); }); function loadTheCharts() { // These are the functions that were loaded dynamically // By this point the script tag is supposed be loaded, added and eval'd function1(); function2(); } Function1() and function2() don't exist until they get added to the dom, but I don't call loadTheCharts() until after the $.post has run so this doesn't seem to be a problem. I'm one of those dirty PHP coders you mother warned you about, so I'm not well versed in JavaScript beyond what I've read in the typical go-to O'Reilly books. But this code worked fine on my personal dev server, so I'm wondering why it wouldn't work on this new machine. The only difference in setup, from what I can tell, is that the new machine is running on port 8080, so it's 192.168.blah.blah:8080/index.php instead of nicedomain.com/index.php. I see the code was indeed added to the dom when I use webmaster tools to "view generated source" but in Firebug I get an error like "function2() is undefined" even though my understanding was that all script tags are eval'ed when added to . My question: Given what I've laid out, and that the machine is running on :8080, is there a reason anyone can think of as to why a dynamically loaded function like function2() would be defined on the Linode and not on the machine running Apache on 8080?

  • How can I dynamically add an <object> tag with JavaScript in IE?

    - by Detlef D. Doerscheln
    I have to add either an embed tag for Firefox or an object tag for Internet Explorer with JavaScript to address the appropriate ActiveX / Plugin depending on the browser. The plugin could be missing and needs to get downloaded in this case. The dynamically added embed tag for Firefox works as expected. The dynamically added object tag for Internet Explorer seems to do nothing at all. The object tag needs the following attributes to function properly. id ="SomeId" classid = "CLSID:{GUID}" codebase = "http://www.MyActicexSource.com/MyCuteActivex.CAB#Version=2,0,0,1" Even a general working idea or method would be nice. Thanks!
