• 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

• DHCP won't start / subnetting

  - by user114371

  I recently changed the IP address on an Ubuntu 12.04 server I have in my lab, which is running isc-dhcp-server. After doing so and modifying the dhcpd.conf file, my dhcp service would not start. I basically used the same configuration, except I modified everything to use /25 scopes rather than /24. When I try to start / restart the service, I see the following: MY@ubuntuserver:~$ sudo service isc-dhcp-server restart stop: Unknown instance: isc-dhcp-server start/running, process 20918 It looks like it starts, but it isn't actually running and Webmin states that the DHCP service is not running. So my question is, does isc-dhcp-server support subnetting (CIDR) style scopes, or must they be class A / B / C scopes (doesn't seem likely)? I've double checked the interface reference (this is a VM with only one defined eth0 interface) and everything else I can thing of.

• Adding to arrays and printing arrays in Java

  - by nfoggia

  I need help figuring out how to get the user to input a number of integers no more than 10, and then add them to an array and print them out from the array. The code I have below, when run, asks the user for the integers and then runs forever and doesn't work. What am I doing wrong? public static void main(String[] args) { Scanner input = new Scanner(System.in); // create a new scanner System.out.print("Enter integers between 1 and 100\n "); int[] nextNumber = new int[10]; int i = 0; int number = input.nextInt(); while (i < nextNumber.length){ i++; nextNumber[i] = number; number = input.nextInt(); } int a = 0; while (a < nextNumber.length){ a++; System.out.println(nextNumber[a]); }

• 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?

• Can a repeated piece of regular expression create multiple groups? Such as this example...

  - by Yousui

  Hi guys, I'm using RUBY 's regular expression to deal with text such as ${1:aaa|bbbb} ${233:aaa | bbbb | ccc ccccc } ${34: aaa | bbbb | cccccccc |d} ${343: aaa | bbbb | cccccccc |dddddd ddddddddd} ${3443:a aa|bbbb|cccccccc|d} ${353:aa a| b b b b | c c c c c c c c | dddddd} I want to get the trimed text between each pipe line. For example, for the first line of my upper example, I want to get the result aaa and bbbb, for the second line, I want aaa, bbbb and ccc ccccc. Now I have wrote a piece of regular expression and a piece of ruby code to test it: array = "${33:aaa|bbbb|cccccccc}".scan(/\$\{\s*(\d+)\s*:(\s*[^\|]+\s*)(?:\|(\s*[^\|]+\s*))+\}/) puts array Now my problem is the (?:\|(\s*[^\|]+\s*))+ part can't create multiple groups. I don't know how to solve this problem, because the number of text I need in each line is variable. Anyone can help? Great thanks.

• Regular Expression for $_GET query strings

I've tried, for example something like this: (\?)(.*)(=)(.*) but without result... Any regexp gurus here? / Tobias

• Commenting/In-Code Documentation Styles

  - by Maxpm

  This might be a stupid question, but it's been in the back of my head for a while and I can't find a decent answer anywhere else. I have a teacher who says we should explicitly list each parameter with a description, even if there's only one. This leads to a lot of repetition: double MyFunction(const int MyParam); // Function: MyFunction // Summary: Does stuff with MyParam. // Input: int MyParam - The number to do stuff with. // Output: MyParam with stuff done to it. When writing in-code documentation, how detailed are you?

• Can I copy large files faster without using the file cache?

  - by Veazer

  After adding the preload package, my applications seem to speed up but if I copy a large file, the file cache grows by more than double the size of the file. By transferring a single 3-4 GB virtualbox image or video file to an external drive, this huge cache seems to remove all the preloaded applications from memory, leading to increased load times and general performance drops. Is there a way to copy large, multi-gigabyte files without caching them (i.e. bypassing the file cache)? Or a way to whitelist or blacklist specific folders from being cached?

• Python Parse CSV Correctly

  - by cornerstone

  I am very new to Python. I want to parse a csv file such that it will recognize quoted values - For example 1997,Ford,E350,"Super, luxurious truck" should be split as ('1997', 'Ford', 'E350', 'Super, luxurious truck') and NOT ('1997', 'Ford', 'E350', '"Super', ' luxurious truck"') the above is what I get if I use something like str.split(). How do I do this? Also would it be best to store these values in an array or some other data structure? because after I get these values from the csv I want to be able to easily choose, lets say any two of the columns and store it as another array or some other data structure. Thanks in advance.

• JQuery: which element was clicked?

  - by centr0

  I have a list with links. These links are links to tables on the same page. What I want to do is whatever link I click in the list it will show its corresponding table and hide all the others. Without adding a different id/class to each link in the list and its corresponding table, is there a way to find out which element was clicked and show() its table? From what I understand JQuery returns an array object on its selector. How can I find out what element of the array was clicked? I've tried to use event.which but I'm a little lost. Help is greatly appreciated!
