  • how to change color of text following function in javascript

    - by OVERTONE
    Ok before i make spaghetti of this code i thought id ask around here. ive made a quiz for an online site. The answers are stored in an array, and ive a function that checks the answers array to what youve clicked. then it counts them and gives you your score. but i want to change the clor of the right answer wen the user clicks the score button. so the correct answers are highlighted. something like this https://www.shutterpoint.com/Home-Quiz.cfm (just hit submit at the bottom, no need to do the quiz). the little answer icon at the side looks flashy but id rather just have the text change color. heres how my questions are formatted <p>Depth of field is controlled by :?</p> <p id = "question2"><input type="radio" name="question2" id="Answer1" value = "a" onClick ="recordAnswer(2,this.value)"/> The focal length of the lens. <br/> <input type="radio" name="question2" id="Answer2" value = "b" onClick = "recordAnswer(2,this.value)"/> The size of the aperture opening. <br/> <input type="radio" name="question2" id="Answer3" value = "c" onClick = "recordAnswer(2,this.value)"/> The distance between the camera and lens. <br/> <input type="radio" name="question2" id="Answer4" value = "d" onClick = "recordAnswer(2,this.value)"/> All of these. <br/></p> and these are the two functions that are called throughout. record answer is called every time the user clicks a button function recordAnswer(question,answer) { answers[question-1] = answer; } this is the final button which calculates the score function scoreQuiz() { var totalCorrect = 0; for(var count = 0; count<correctAnswers.length;count++) { if(answers[count]== correctAnswers[count]) totalCorrect++; } <!-- alert("You scored " + totalCorrect + " out of 12 correct!"); --> } another function is best i think. ive already made attemots at it and know i have to set the color using document.getElementById('question2').style.color = '#0000ff'; question2 being the p id i think if i take in the value part of (input type....) ill be able to compare it to the answers array. but im not quite sure how to do this. any helpers? maybe something like this document.getElementById("Answer1").style.color = '#0000ff'; using the id part of the (input type line) i think i got it actually. ill post my answer in a sec

  • I'm new to C++. Please Help me with the Linked List (What functions to add)?

    - by Igal
    DEAR All; Hi, I'm just beginner to C++; Please help me to understand: What functions should be in the Linked list class ?

  • Testing for the existence of a field in a class

    - by Brett
    Hi, i have a quick question. I have a 2D array that stores an instance of a class. The elements of the array are assigned a particular class based on a text file that is read earlier in the program. Since i do not know without looking in the file what class is stored at a particular element i could refer to a field that doesn't exist at that index (referring to appearance when an instance of temp is stored in that index). i have come up with a method of testing this, but it is long winded and requires a second matrix. Is there a function to test for the existence of a field in a class? class temp(): name = "default" class temp1(): appearance = "@"

  • PHP - Get dates of next 5 weekdays?

    - by Dan
    I'm trying to create an array of the next 5 working week days (Monday - Friday, excluding today). I know the working week varies around the world but this is not important for what I am trying to do. So, for example, if today is a Wednesday, I want the dates for Thursday and Friday of the current week and Monday, Tuesday and Wednesday of the following week. I thought this would work: $dates = array(); for ($i = 1; $ < 6; $i ++) { $dates[] = date('Y-m-d', strtotime('+ '.$i.' weekday')); } But for today, it is giving me: Monday 1st Tuesday 2nd Wednesday 3rd Thursday 4th Sunday 7th! Any advice appreciated. Thanks

    - by Mrt
    Hello, I'm adding a custom method to jquery validation that calls a webservice, but the web service returns more then just a boolean. Is it possible to show the error based on return call of the web service. e.g. say I want an email address to be valid & not in use, so my web service checks this an returns 0 - ok, 1 - not valid, 2 - in use. How can I get jquery to show to correct error message based in the response ?

    Write a program to read in a file containing the names of the employ of a company and store them in an array of Strings named Employ []. Read another file containing the Salaries of each employ written in the same order and store them in another array of integers named salary[] (contents of both files are shown below). Finally create a file stating for example. Mr. XYZ receive $75,500.00 per year (Note that salary is stored as integer but displayed here as double with a comma separating thousands. This formatting needs to be done using DecimalFormat Class)

  • Google App Engine - Dealing with concurrency issues of storing an object

    - by Spines
    My User object that I want to create and store in the datastore has an email, and a username. How do I make sure when creating my User object that another User object doesn't also have either the same email or the same username? If I just do a query to see if any other users have already used the username or the email, then there could be a race condition. UPDATE: The solution I'm currently considering is to use the MemCache to implement a locking mechanism. I would acquire 2 locks before trying to store the User object in the datastore. First a lock that locks based on email, then another that locks based on username. Since creating new User objects only happens at user registration time, and it's even rarer that two people try to use either the same username or the same email, I think it's okay to take the performance hit of locking. I'm thinking of using the MemCache locking code that is here: http://appengine-cookbook.appspot.com/recipe/mutex-using-memcache-api/ What do you guys think?

  • Doctrine: Relating a model to itself using a link table, like "This event is related to to the following other events"

    - by mattalexx
    So in English, the relationship would sound like "This event is related to to the following other events". My first instinct is to create an EventEvent model, with a first_event_id field and a second_event_id field. Then I would define the following two relationships in the Event model: $this->hasMany('Event as FirstRelatedEvents', array('local' => 'first_event_id', 'foreign' => 'second_event_id', 'refClass' => 'EventEvent')); $this->hasMany('Event as SecondRelatedEvents', array('local' => 'second_event_id', 'foreign' => 'first_event_id', 'refClass' => 'EventEvent')); But I would rather not have to use two relationships on the Event model. Is there a better way to do this?

  • How to resize a silverlight control to a full webpage.

    - by ForeverDebugging
    I'm currently using a datagrid within a user control. The datagrid resizes based on the number of rows, and therefore goes off the webpage. I've tried wrapping the control around a ScrollViewer, but in order to have the scroll bar visible and working, I need to set the MaxHeight of the datagrid. The problem is that I don't know what the MaxHeight of the datagrid should be because it differs based on the size of the browser window appearing on the screen. Any suggestions on how to determine the correct size of the control?

  • Caching using hibernate

    - by Subhendu Mahanta
    I have 2 applications.First one is a web application through which we provision reference data.Second one is an ESB based application where the reference data is used.The reference data changes but not very frequently.We needed to cache the reference data.The web application( I am not the owner) used hibernate. But my ESB based application did not.We only used EHCache. When reference data is changed by the independent web application that needs to be reflected in ESB application.We implemented using message queue - that is when reference data changes web application sends a message to the message queue.Our ESB application listens to that message & clears the cache & caches the data once again.This works.But it is time intensive.How can I use Hibernate to improve the situation? Regards, Subhendu

  • Breakdown of this Ruby code?

    - by randombits
    Would anyone be kind enough to dissect the merge! method? Its usage of conditions and variable assignment looks rather terse, and I'm having a difficult time following it.

  • How does PHP's list function work?

    - by Jacob Relkin
    After recently answering a couple of questions here on SO that involved utilizing PHP's list function, I wondered, "how in the world does that function actually work under the hood?". I was thinking about something like using func_get_args() and then iterating through the argument list, and that's all nice and peachy, but then how in the world does the assignment part work? list(...) = array($x, $y, $z); isn't this ^ evaluated first? So to be precise, my question is how is the list function able to create scoped variables which get assigned to the not-yet evaluated array?

  • Anyone have a good solution for scraping the HTML source of a page with content (in this case, HTML

    - by phpwns
    Anyone have a good solution for scraping the HTML source of a page with content (in this case, HTML tables) generated with Javascript? An embarrassingly simple, though workable solution using Crowbar: <?php function get_html($url) // $url must be urlencode(d) { $context = stream_context_create(array( 'http' => array('timeout' => 120) // HTTP timeout in seconds )); $html = substr(file_get_contents('http://127.0.0.1:10000/?url=' . $url . '&delay=3000&view=browser', 0, $context), 730, -32); // substr removes HTML from the Crowbar web service, returning only the $url HTML return $html; } ?> The advantage to using Crowbar is that the tables will be rendered (and accessible) thanks to the headless mozilla-based browser. The problem, of course, is being dependent on on an external web service, especially given that SIMILE seems to undergo regular server maintenance. :( A pure php solution would be nice, but any functional (and reliable) alternatives would be great.

  • PHP: Is there an elegant way to foreach through multiple items (groups) at a time?

    - by acheong87
    Given an array of N items: $arr = array('a', 'b', 'c', 'd', 'e', 'f'); What's the most elegant way to loop through in groups of M items (assuming N is divisible by M)? I tried foreach (array_chunk($arr, 2) as list($first, $second)) { // do stuff with $first and $second } but this resulted in a syntax error. In other words, I want to emulate what in Tcl would look like this: set arr [a b c d e f] foreach {first second} $arr { // do stuff with $first and $second } For now I've resorted to the obvious measure: foreach (array_chunk($arr, 2) as $group) { $first = $group[0]; $second = $group[1]; // do stuff with $first and $second } But I'm hoping someone has a more elegant method...

  • How to solve the leaks when allocating the NSMutableArray in Objective-C

    - by Madan Mohan
    Hi Guys, I am getting leaks in Master view controller of iPhone. When I call this method, I am inserting them into filteredListCount array, because when I search I need to show the list from filteredListCount array otherwise customerArray. This functionality is working fine but I am getting leaks in the method below at allocation: filteredListCount = [[NSMutableArray alloc] initWithCapacity: [customerArray count]]; This is the first view controller of my application, I am showing the list and I am also allowing to search from a list. - (void)parser:(CustomerListLibXmlParser *)parser addCustomerObject:(Customer *)customerObj1 { [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; [customerArray addObject:customerObj1]; filteredListCount = [[NSMutableArray alloc] initWithCapacity: [customerArray count]]; [filteredListCount addObjectsFromArray: customerArray]; [theTableView reloadData]; } - (void)parser:(CustomerListLibXmlParser *)parser encounteredError:(NSError *)error { } - (void)parserFinished:(CustomerListLibXmlParser *)parser { [UIApplication sharedApplication].networkActivityIndicatorVisible = NO; self.title=@"Customers"; }

  • Problem with layout of control when dynamically creating winform and controls for the Form

    - by Ashwani Roy
    I get this response from a web service call. Something like this <Response> <Control1 type = "DropdownList" value= "USA,UK,Sweden,UAE"/> <Control2 type = "Textbox" value= "Contries"/> <Control3 type = "Button" value= "None"> </Response> Based on this I de-serialize it into List<Controls>. Now I need to be able to dynamically create a winform based on these controls. My problem is the layout. I want to be able to create them nicely separated (If possible vertically aligned) in batches of lets say 5.So If I need 15 controls I have 3 columns and 5 rows. What would be best way to achieve this? I know that I can use the inbuilt positioning properties like top, width etc., but maybe someone out there has done something similar in a better way.

  • Spring Jdbc Template + MySQL = TransientDataAccessResourceException : Invalid Argument Value : Java.

    I was using spring jdbc template to insert some data into the database and I was getting this error. Here is my code : JdbcTemplate insert = new JdbcTemplate(dataSource); for(ResultType result : response.getResultSet().getResult()) { Object[] args = new Object[] {result.getAddress(), result.getCity(), result.getState(), result.getPhone(), result.getLatitude(), result.getLongitude(),result.getRating().getAverageRating(), result.getRating().getAverageRating(), result.getRating().getTotalRatings(), result.getRating().getTotalReviews(), result.getRating().getLastReviewDate(), result.getRating().getLastReviewIntro(), result.getDistance(), result.getUrl(), result.getClickUrl(), result.getBusinessUrl(), result.getBusinessClickUrl()}; insert.update("INSERT INTO data.carwashes ( address, city, state, phone, lat, lng, rating, average_rating, total_ratings, total reviews, last_review_date, last_review_intro, distance, url, click_url, business_url, business_click_url, category_id, zipcode_id) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?,96925724,78701)", args); } Quite lengthy code.. but, basically it gets the value from a object and sticks it to a array and passed that array to insert method of jdbc template. Any help will be appreciated.

  • Is there a Java equivalent for Ruby on Rails "url_for"?

    - by Oren Ben-Kiki
    I have written something like this pretty easily in C# (string GetUrl(new { controller = "foo", action = "bar", baz = "fnord" }), based on the existing capabilities of the XmlRouteCollection class provided by the ASP.NET MVC framework (why it isn't there out of the box is beyond me; the additional required code was trivial). I am now faced with a JSP project, and I need the same ability: centralize the logic for generating all URLs in one place, based on a list of routing rules. Is there some code somewhere I could reuse/adapt to do this in Java? It seems like a common enough requirement, but google proved surprisingly unhelpful in finding something like this.

  • Oracle SQL Update query takes days to update

    - by B Senthil Kumar
    I am trying to update a record in the target table based on the record coming in from source. For instance, if the incoming record is present in the target table I would update them in the target else I would simply insert. I have over one million records in my source while my target has 46 million records. The target table is partitioned based on calendar key. I implement this whole logic using Informatica. I find that the Informatica code is perfectly fine looking at the Informatica session log but its in the update it takes long time (more than 5 days to update one million records). Any suggestions as to what can be done on the scenario to improve the performance?

  • Javascript: Save json data as a file on the server / user's hard disk.

    - by DavidR
    I have developed an app that allows the user to fill out text fields with information. I want them to be able to press a button that will make a file with data (a really long array with info on what they typed and where it should go) so they can reload the data at a later date. I don't have a server now, and I am sending this app as a standalone html app to my friends for their use until I get hosing / mySql / etc. Is there a way that when they click on a button it will take this data (saved as an array, save_data), put it into a file, and basically begin the download process from their web-browser? And later on, what tech would I need to be looking into to save this into online user accounts?

  • Buy or build tool for Data Reporting ?

    - by Manoj
    We have been asked to provide a data reporting solution. The followng are the requirements: i. The client has a lot of data which is generated everyday as an outcome of the tests they run. These tests are run at several sites and they get automatically backed up into a central server. ii. They already have perl scripts which post process them and generates excel based reports. iii. They need a web based interface for comparing those reports and they need to mark and track issues which might be present in those data. I am confused if we should build our own tool for this or we should go for already exiting tool(any suggestions?). Can you please provide supportive arguments for the decision that you would suggest?
