  • Building my first Javascript Application (jQuery), struggling on something

    - by Jason Wells
    I'd really appreciate recommendations on the most efficient way to approach this. I'm building a simple javascript application which displays a list of records and allows the user to edit a record by clicking an "Edit" link in the records row. The user also can click the "Add" link to pop open a dialog allowing them to add a new record. Here's a working prototype of this: http://jsfiddle.net/FfRcG/ You'll note if you click "Edit" a dialog pops up with some canned values. And, if you click "Add", a dialog pops up with empty values. I need help on how to approach two problems I believe we need to pass our index to our edit dialog and reference the values within the JSON, but I am unsure how to pass the index when the user clicks edit. It bothers me that the Edit and Add div contents are so similiar (Edit just pre populates the values). I feel like there is a more efficient way of doing this but am at a loss. Here is my code for reference $(document).ready( function(){ // Our JSON (This would actually be coming from an AJAX database call) people = { "COLUMNS":["DATEMODIFIED", "NAME","AGE"], "DATA":[ ["9/6/2012", "Person 1","32"], ["9/5/2012","Person 2","23"] ] } // Here we loop over our JSON and build our HTML (Will refactor to use templating eventually) members = people.DATA; var newcontent = '<table width=50%><tr><td>date</td><td>name</td><td>age</td><td></td></tr>'; for(var i=0;i<members.length;i++) { newcontent+= '<tr id="member'+i+'"><td>' + members[i][0] + '</td>'; newcontent+= '<td>' + members[i][1] + '</td>'; newcontent+= '<td>' + members[i][2] + '</td>'; newcontent+= '<td><a href="#" class="edit" id=edit'+i+'>Edit</a></td><td>'; } newcontent += "</table>"; $("#result").html(newcontent); // Bind a dialog to the edit link $(".edit").click( function(){ // Trigger our dialog to open $("#edit").dialog("open"); // Not sure the most efficient way to change our dialog field values $("#name").val() // ??? alert($()); return false; }); // Bind a dialog to the add link $(".edit").click( function(){ // Trigger our dialog to open $("#add").dialog("open"); return false; }); // Bind a dialog to our edit DIV $("#edit").dialog(); // Bind a dialog to our add DIV $("#add").dialog(); }); And here's the HTML <h1>People</h1> <a href="#" class="add">Add a new person</a> <!-- Where results show up --> <div id="result"></div> <!-- Here's our edit DIV - I am not clear as to the best way to pass the index in our JSON so that we can reference positions in our array to pre populate the input values. --> <div id="edit"> <form> <p>Name:<br/><input type="text" id="name" value="foo"></p> <p>Age:<br/><input type="text" id="age" value="33"></p> <input type="submit" value="Save" id="submitEdit"> </form> </div> <!-- Here's our add DIV - This layout is so similiar to our edit dialog. What is the most efficient way to handle a situation like this? --> <div id="add"> <form> <p>Name:<br/><input type="text" id="name"></p> <p>Age:<br/><input type="text" id="age"></p> <input type="submit" value="Save" id="submitEdit"> </form> </div>

  • How to Omit the Page Number From the First Page of a Word 2013 Document Without Using Sections

    - by Lori Kaufman
    Normally, the first page, or cover page, of a document does not have a page number or other header or footer text. You can avoid putting a page number on the first page using sections, but there is an easier way to do this. If you don’t plan to use sections in any other part of your document, you may want to avoid using them completely. We will show you how to easily take the page number off the cover page and start the page numbering at one on the second page of your document by simply using a footer (or a header) and changing one setting. Click the Page Layout tab. In the Page Setup section of the Page Layout tab, click the Page Setup dialog box launcher icon in the lower, right corner of the section. On the Page Setup dialog box, click the Layout tab and select the Different first page check box in the Headers and footers section so there is a check mark in the box. Click OK. You’ll notice there is no page number on the first page of your document now. However, you might want the second page to be page one of your document, only to find it is currently page two. To change the page number on the second page to one, click the Insert tab. In the Header & Footer section of the Insert tab, click Page Number and select Format Page Numbers from the drop-down menu. On the Page Number Format dialog box, select Start at in the Page numbering section. Enter 0 in the edit box and click OK. This allows the second page of your document to be labeled as page one. You can use the drop-down menu on the Format Page Numbers button in the Header & Footer section of the Insert tab to add page numbers to your document as well. Easily insert formatted page numbers at the top or bottom of the page or in the page margins. Use the same menu to remove page numbers from your document.

  • First Project a big one, How much should we charge?

    - by confuzzled
    Two of my cousins and I started a freelance computer repair/web design business just to make some money on the side during college, and received our first major web design project about three weeks ago. Now we've created websites before, but it was mostly for family businesses and have never really charged money, and most of the websites have been static, and don't really require a CMS. This project, however, was a big one (for us anyways). We created a news site that had several categories, we created the banners, we created a classifieds page (not a web app just something static that they control). Several links, a few graphical assets, CSS drop down menu, RSS feed from a different news site, weather, all the normal stuff you would find on a regular news site. On top of that we put in all the usual Joomla stuff (search, Jcomments, Jslide pictures, JCE, etc.). Then we uploaded the first 10 articles they gave us, and we are going to train them how to use Joomla. Now, at first we decided for 700 dollars. I assumed they just wanted a simple blog like website where they can upload articles. But then we had a meeting, and they asked for a lot more. Note: we did not hard code the template from scratch, but customized the gantry framework to fit their needs. We did code quite a bit however. I estimate that we put in about 50-60 hours in total. I'm wondering if 700 dollars is a bit low, this price is definitely not set in stone. Please keep in mind that this is our first project, and we are newbies, please be kind. Thank You!

  • Would you recommend Head First Programming for someone new?

    - by Sergio
    My brother is just starting out college. He's studying the same thing I am here in Bolivia; Systems Engineer which is the equivalent of what a CS degree is in the US. Being his big brother and a programmer myself I really want to guide him and give him the right material to learn and become good at programming. My motives are selfish I admit, I want him to become really good so he can teach me things in the future. :) After poking around the web, I found Head First Programming. This book seems to teach the fundamentals of programming, using Python as the language. Would you recommend this book as his first book ever? Would learning Python as his first language stunt him somehow? What are your thoughts and suggestions? Thanks!

  • When should I make the first commit to source control?

    - by Kendall Frey
    I'm never sure when a project is far enough along to first commit to source control. I tend to put off committing until the project is 'framework-complete' and primarily commit features from then on. (I haven't done any personal projects large enough to have a core framework too big for this.) I have a feeling this isn't best practice, though I'm not sure what all could go wrong. Let's say, for example, I have a project which consists of a single code file. It will take about 10 lines of boilerplate code, and 100 lines to get the project working with extremely basic functionality (1 or 2 features). Should I first check in: The empty file? The boilerplate code? The first features? At some other point? Also, what are the reasons to check in at a specific point?

  • Is it true that first versions of C compilers ran for dozens of minutes and required swapping floppy disks between stages?

    - by sharptooth
    Inspired by this question. I heard that some very very early versions of C compilers for personal computers (I guess it's around 1980) resided on two or three floppy disks and so in order to compile a program one had to first insert the disk with "first pass", run the "first pass", then change to the disk with "second pass", run that, then do the same for the "third pass". Each pass ran for dozens of minutes so the developer lost lots of time in case of even a typo. How realistic is that claim? What were actual figures and details?

  • Does Bing support anything like Google's First Click Free program?

    - by Dan Fabulich
    Google has a program for webmasters called First Click Free. To implement First Click Free, you need to allow all users who find a document on your site via Google search to see the full text of that document, even if they have not registered or subscribed to see that content. The user's first click to your content area is free. However, once that user clicks a link on the original page, you can require them to sign in or register to read further. The user must be able to see the full content of a multi-page article. You can allow this by displaying all content on a single page to both Googlebot and users. Alternatively, you can use cookies to make sure that a user can visit each page of a multi-page article before being asked for registration or payment. Does Bing support anything like this?

  • Keeping the camera from going through walls in a first person game in Unity?

    - by Timothy Williams
    I'm using a modified version of the standard Unity First Person Controller. At the moment when I stand near walls, the camera clips through and lets me see through the wall. I know about camera occlusion and have implemented it in 3rd person games, but I have no clue how I'd accomplish this in a first person game, since the camera doesn't move from the player at all. How do other people accomplish this?

  • in iOS7 how do you stop the First viewcontroller autorotating?

    - by uaka
    I have an app that just needs one screen to autorotate, the first and last screens should be portrait. I can get the last screen to stop rotating using: -(NSUInteger)supportedInterfaceOrientations { return UIInterfaceOrientationMaskPortrait; } But this does not work on the first screen, I am using a storyboard with a UINavigationController (I'm thinking that may have something to do with it?) Any help would be gratefully received. Thanks

  • Is it better to learn the DOM or jQuery first?

    - by user1146440
    I have gotten very familiar with the core functionality of Javascript and now I am aiming at learning DOM manipulation. I have already thought of learning jQeury for this but I don't know if it is good idea to learning it before first getting familiar with the core functionality of the DOM. Should I first learn the core functionality of the DOM and then learn jQuery? If so, why? Or should I just go on ahead and learn jQuery?

  • Does TDD's "Obvious Implementation" mean code first, test after?

    - by natasky
    My friend and I are relatively new TDD and have a dispute about the "Obvious Implementation" technique (from "TDD By Example" by Kent Beck). My friend says it means that if the implementation is obvious, you should go ahead and write it - before any test for that new behavior. And indeed the book says: How do you implement simple operations? Just implement them. Also: Sometimes you are sure you know how to implement an operation. Go ahead. I think what the author means is you should test first, and then "just implement" it - as opposed to the "Fake It ('Till You Make It)" and other techniques, which require smaller steps in the implementation stage. Also after these quotes the author talks about getting "red bars" (failing tests) when doing "Obvious Implementation" - how can you get a red bar without a test?. Yet I couldn't find any quote from the book saying "obvious" still means test first. What do you think? Should we test first or after when the implementation is "obvious" (according to TDD, of course)? Do you know a book or blog post saying just that?

  • Why is C++ often the first language taught in college?

    - by Casey Patton
    My school starts the computer science curriculum with C++ programming courses, meaning this is the first language that many of the students learn. I've seen that many people dislike C++, and I've read a variety of reasons why. It almost seems to be popular opinion that C++ isn't a very good language. I get the impression it's not very liked based on some questions on StackExchange as well as posts such as: http://damienkatz.net/2004/08/why-c-sucks.html http://blogs.kde.org/node/2298 http://blogs.cio.com/esther_schindler/linus_torvalds_why_c_sucks http://www.dacris.com/blog/2010/02/16/why-c-sucks-part-2/ etc. (Note: It is not my opinion that C++ is a bad language. In fact, it's the main language I use. However, the internet as well as some professors have given me the impression that it's not a very widely liked language. In fact, one of my professor constantly rags on C++, yet it's still the starting language at my college!) With that in mind, why is this the first language taught at many schools? What are the reasons for starting a programming curriculum with C++? Note: This question is similar to "Is C++ suitable as a first language", but is a little different since I'm not interested in whether it's suitable, but why it's been chosen.

  • Are first-class functions a substitute for the Strategy pattern?

    - by Prog
    The Strategy design pattern is often regarded as a substitute for first-class functions in languages that lack them. So for example say you wanted to pass functionality into an object. In Java you'd have to pass in the object another object which encapsulates the desired behavior. In a language such as Ruby, you'd just pass the functionality itself in the form of an annonymous function. However I was thinking about it and decided that maybe Strategy offers more than a plain annonymous function does. This is because an object can hold state that exists independently of the period when it's method runs. However an annonymous function by itself can only hold state that ceases to exist the moment the function finishes execution. So my question is: when using a language that features first-class functions, would you ever use the Strategy pattern (i.e. encapsulate the functionality you want to pass around in an explicit object), or would you always use an annonymous function? When would you decide to use Strategy when you can use a first-class function?

  • 3 column layout with css display table, with first row having multiple rows?

    - by Damainman
    I am working on a new website which: Has 3 columns - Each Column being a cell First column has 3 rows (Logo, Nav, icons) - Has a Div with display: table which wraps arround 3 divs with display:table-row. Other two columns only have 1 row. With the middle column being the content area. However since this is my first time using display:table, I am running into some things that aren't so clear to me. I was trying to avoid floating divs. If I need multiple rows with one cell in each row per column, do I embed each cell in a row or just create each row and not declare cells. I understand that browsers automatically create the missing elements but I want to make sure I do this properly to avoid any side effects that might occur due to the browser automatically creating the missing elements. Edit: I think my brain is just over worked, I guess I can accomplish this by just using 3 divs in the first column instead of using a nested table div with the rows. This just popped into my head.

  • Word 2010 header "different first page" option does not work if you select the same built-in header preset?

    - by fredsbend
    I have a three page Word 2010 document. I have set a header on the first page and marked the "different first page" option to make the follow page headers different. It works as expected so long as I don't select the same built-in header preset for the following pages. Here's what I am doing: Check mark different first page. Make the header for the first page using Alphabet preset. Attempt to make the header for the following pages by starting with the same Alphabet preset. I only want to change the text of the following headers but still want the same graphical effects. Click off the header into the body of the document. Upon doing this the headers on the first page are updated to the ones I just made for the following pages. I don't I am doing something wrong because I can choose a different header preset and it will work as expected. If I select the same preset, however, it updates all headers, whether the "different on first page" is selected or not. If this is repeatable on others' computers the I would say it's a word bug. If not then please help me figure out how to get this working right.

  • Java Variable Initialization

    - by Samuel Brainard
    Here's a piece of code I wrote. public class cube { private int length; private int breadth; private int height; private int volume; private int density; private int weight; public cube(int l,int b,int h, int d) { length=l; breadth=b; height=h; density=d; } public void volmeShow(){ volume=length*breadth*height; System.out.println("The Volume of the cube is "+this.volume); So if I implement the above cube class like this, public class cubeApp { public static void main(String[] args){ cube mycube = new cube(5,6,9,2); mycube.volumeShow(); I get an output that tells me Volume is 270. But I get an output that says Volume is 0 if I define the volume variable like this: public class cube { private int length; private int breadth; private int height; private int volume=length*breadth*height; private int density; private int weight; public cube(int l,int b,int h, int d) { length=l; breadth=b; height=h; density=d; } public void volmeShow(){ System.out.println("The Volume of the cube is "+this.volume); Can somebody please explain why this is happening? Thanks, Samuel.
