JavaScript - Bluelj Help - Multiple Choice Quiz
Hello all,
Making a multiple choice quiz using Blue J. My task is to enable the user to add questions and answers. Replace and remove specific answers and questions. Print out all the questions and answers once they are finished. Then quit the program. The user will also need to be able to quit the program at anytime. I am having trouble understanding how i would go about doing this, i figured i would store all the questions using an array or array list? Similar TutorialsI was wondering if someone could help me? In my code below what if answers in question 2 were allowed to be in any order? Like: hips,body,knees or knees,hips,body and so on. How should I modify my code? Anyone please????

Hi! I'm trying to make a multiple choice quiz using javascript. I downloaded codes from http://www.javascriptkit.com/script/cut180.shtml But when I used it nothing comes up on the results (number of correct answer, number of wrong answer and percentage) as well as the solution box is empty. I tried it on Google Chrome and it says "Your browser does not accept cookies. Please adjust your settings." So I tried it in Safari because that's what we use in school and it doesn't work. The results and solution box is empty. I am guessing that problem is with cookies? Please help me. Here are my codes: - Quiz //Enter total number of questions: var totalquestions=10 //Enter the solutions corresponding to each question: var correctchoices=new Array() correctchoices[1]='a' //question 1 solution correctchoices[2]='d' //question 2 solution, and so on. correctchoices[3]='b' correctchoices[4]='b' correctchoices[5]='c' correctchoices[6]='b' correctchoices[7]='a' correctchoices[8]='c' correctchoices[9]='d' correctchoices[10]='b' /////Don't edit beyond here////////////////////////// function gradeit(){ var incorrect=null for (q=1;q<=totalquestions;q++){ var thequestion=eval("document.myquiz.question"+q) for (c=0;c<thequestion.length;c++){ if (thequestion[c].checked==true) actualchoices[q]=thequestion[c].value } if (actualchoices[q]!=correctchoices[q]){ //process an incorrect choice if (incorrect==null) incorrect=q else incorrect+="/"+q } } if (incorrect==null) incorrect="a/b" document.cookie='q='+incorrect if (document.cookie=='') alert("Your browser does not accept cookies.

I've been trying to find out what is wrong with my codes for a week. Thanks in advance! I am working with the quiz found below (Multiple Choice Quiz that is instantly graded/checked), and would like to add pictures to the questions and rollover sound effects. I have figured how to add the picture, but not the sound. Sound effects are played when added to the html section, but not when added to the javascript coding.

Hello, I am currently making a multiple choice program in JS using 3 arrays, one to call the question, one to store the user answer and one to store the real answer. The answers will then be compared to find the score. I have done most of it, but am still having one problem, I am using prompts and when I call the question, only the text in the if statement "qArray[counter]" is actually showing on the prompt and not the actual question from the array and I wondered if anyone could help? Thanks <html> <head><B>Multiple Choice Quiz</B> </head> <body> <script language = 'JavaScript'> document.write('<br><br>This program allows multiple choice questions to be asked - once finished a calculation will total your score.<br>'); qArray = new Array(); qArray = ['What is the capital of England? London/Paris/Cardiff/Berlin', 'What is the capital of France? London/Paris/Cardiff/Berlin', 'What is the capital of Wales? London/Paris/Cardiff/Berlin', 'What is the capital of Germany? London/Paris/Cardiff/Berlin']; aArray = new Array(); aArray = ['London', 'Paris', 'Cardiff', 'Berlin']; //array of the answers counter = 0; NumberofQuestions = 4; score = 0; while (counter < NumberofQuestions){ if (counter == 0){ question1=prompt('qArray[counter]',''); } if (counter == 1){ question2=prompt('qArray[counter]',''); } if (counter == 2){ question3=prompt('qArray[counter]',''); } if (counter == 3){ question4=prompt('qArray[counter]',''); } counter++; } studentAnswers = new Array(); studentAnswers = [question1, question2, question3, question4]; //an array with the answers the student has inputted counter = 0; while (counter < NumberofQuestions){ if (studentAnswers[counter] == aArray[counter]){ score++; } counter++; } document.write ('You have finished the quiz, your total marks will be calculated.'); //inform student that they have finished document.write('You scored: ',score,' /4'); //prints the score to screen. </script> </body> </html> I have just used an Analysis Quiz tool (on this page http://javascript.about.com/library/blquizf.htm) to create a quiz which doesn't have right or wrong answers but adds the scores of the answers together. It all works nicely, HOWEVER I require 5 answers as opposed to the maximum of four which has been offered on this site. The (partial) code is: Code: var quiz = new Array(); var r = 0;
var analPage = 'result.html';
quiz[r++] =('93726~71~1. How often do you have a drink containing alcohol?~Never~Once a month or less~2 to 4 times a month~2 to 3 times a week~0~3');
quiz[r++] =('48844~37~How many units of alcohol do you have on a typical day when you are drinking?~1-2~3-4~5-6~7-9~0~3');
I thought it would be straight forward and I could add another option at the end of each string and then change the scoring e.g. quiz[r++] =('93726~71~1. How often do you have a drink containing alcohol?~Never~Once a month or less~2 to 4 times a month~2 to 3 times a week~4 or more times a week~0~4'); but this didn't work ... please help! Thank you Hello, I am trying to figure out how to write a quiz that has one question per html page, then once the choice has been selected, it will go to another page and tally a total at the end. Can this be done? And if so, can you point me in the right direction to research? Thanks in advance, Tanya I've got a form that performs a calculation upon submit. I want it to perform a different calc depending on the choice from a drop down box in the form. Are there any examples of this? or can someone explain how i do it? thanks Is an iframe the only way to embed a web page? I would like to embed a web page within a email but some users email clients do not support iframes.
Hi, I've checked the boards and was unable to find something that matched the code that I have. The code basically uses radio buttons to populate results to a drop-down list depending on the radio button they choose. I'm having trouble figuring out where and how to add the redirection url for each of the value choices in the drop down. I was told something about using window.location('http://url.here') and then to populate the location parameter with the array value. Does this mean I have to redo my script or can another piece of code be added on to make it work. How do I alter my existing code? Thanks in advance for any help I can get: Code:

Hi, I have a web form that I'm creating and it has some expandable checkboxes that need to be restricted based on choice. This is my criteria: If someone chooses checkbox number 1, they cannot choose any other checkbox. If someone chooses checkbox number 2, they may also choose number 3 but not 1 or 4, they must also answer the question that appears below. If someone chooses checkbox number 3, they may also choose number 2 but not 1 or 4, they must also answer the question that appears below. If someone chooses checkbox number 4, they cannot choose any other checkbox, and must answer the questions that appears below. One more caveat: If checkbox number 2 is chosen, and they've filled in all three lines of the question below, I need for them to dynamically add more lines as needed. I have attached my web form so you can see what I've done. I've researched these options and tried code from various examples but I can't seem to get it to work. Does anyone know how to accomplish all of this? Thank you in advance! Ok so I have a select box where the value must be passed via the form. If the users selects choice B or Choice C then I want a specific div to show. If they choose choice A then I want the div to hide or remain hidden. It should be hidden on page load. Code: <select name="Event_Type_ID">
<option value="1">Choice A</option>
<option value="2">Choice B</option>
<option value="3">Choice C</option>
</select>
<div id="showme">
Content to show if EITHER Choice B or C is chosen. Otherwise this div should be hidden.
</div>
Can anyone lead me in the right direction? Thanks! Hello All, I'm trying to find a script that would be able to do the following: The are two drop down boxes, the first one populating the second (state/county --> town) The first box is single choice, the second is multiple choice. I'm looking for a script that would be able to deal with generating the code for all possible values that could be chosen in the second drop down box. The drop down boxes are part of a form which allow people to search for educational courses within areas of a state/county. I've had a good root around the internet but am rapidly getting confused ... many thanks in advance. Si. What I would like to do is have a page with a dropdown menu, and depending on which option the user chooses from the dropdown, reload the page and display a particular iframe below the dropdown, based on the users choice. Also, a default iframe would load (the one connected to the default choice in the select box). Hopefully that makes sense. I was trying to make this work with PHP (without having the user having to click a submit button) but I couldn't find a way to make it happen.
I am facing an issue where a link on my website opens in a new window if you simply click on it. However, if you right click and say open in new window or new tab, it opens the same window (URL) again from where the link is clicked. Self Service Option is a link and the JSP calls a function getSelfServSite() when the link is clicked. This is how the code flows in my case function getSelfServSite() { getToTheLink("${myConfigInfo.selfServiceURL}"); // this is because the URL is configurable } function getToTheLink(url) { window.open (url, "currentWindow", ""); } What am I doing wrong. I want it to go to the right link no matter how the user click it. Please advise. Thanks I have a radio button that asks Does your URL exist or need to be purchased? and a drop down menu that lists different types of web projects (i.e. new website and website redesign). What I'm trying to achieve is, if the user selects that the URL exists, I would like the drop down menu option new website to be removed from the list. Form: Code: <form> <input type="radio" name="website_status" value="exists"/> Exists <input type="radio" name="website_status" value="purchase_required"/> Needs to be purchased <select name="projects"> <option></option> <option value="new_website">New Website</option> <option value="website_redesign">Website Redesign</option> </select> </form> JavaScript: [CODE] <script> window.onload = initForms; function initForms() { for (var i=0; i<document.forms.length; i++) { document.forms[i].onsubmit = function() {return validForm();} } } function validForm() { var inputarray = document.getElementsByTagName("input"); var selectarray = document.getElementsByTagName("select"); var textarea = document.getElementsByTagName("textarea"); if (inputarray[0].checked == true) { selectarray[0].remove(options[1]); return false; } </script> I've been experimenting with this for the last couple hours and am getting nothing! Could someone please point me in the right direction? I'm developing a simple game that involves a system of interconnected nodes with unidirectional travel between nodes (similar to the circulation system!). The goal of the game is to get from a starting node to an ending node, which can be a variable number of nodes away. The program picks a random starting point, then randomly chooses one of its connecting nodes (cNodes) and pushes it onto a pathArray. A cNode is randomly chosen from this new node and it is pushed onto the pathArray. This continues for a designated number of turns, thus generating a pathArray (invisible to the player). The last element in the pathArray is the endNode and the goal of the puzzle. At each node the player is given two options of travel (though there may be more than two ways to go). One of these options MUST be the correct way if the player has not deviated from the path up until that point. If the player has deviated, this option can be any cNode. The other node is any cNode that does not lead to the endNode. The following code contains a simplified list of nodes that represents the content in my game. The function, however, is taken word for word. In this snippet, the pathArray & startNode have already been generated and I am trying to resolve how to assign "nodeChoice" as either the correct direction of travel (for a player on the correct path) or any random cNode (for a player who has deviated from the path). Keep in mind that the pathArray and cNodes lengths can be any size. Code: <script>
//NODES:
var nodeA = {name:"A"};
var nodeB = {name:"B"};
var nodeC = {name:"C"};
var nodeD = {name:"D"};
var nodeE = {name:"E"};
var nodeF = {name:"F"};
var nodeG = {name:"G"};

//An array of all nodes in the system:
var systemArray = [nodeA, nodeB, nodeC, nodeD, nodeE, nodeF, nodeG, nodeH, nodeI, nodeJ, nodeK];
//Connecting Nodes (cNodes):

//nodeChoice will represent a cNode from any given node
var nodeChoice;
//chooseNode is supposed to assign nodeChoice the next element in pathArray if the player on on the right path (if at nodeB, nodeChoice = nodeE).
//However, if the user has taken a different path, its cNodes will not be in pathArray in which case a random cNode is assigned to nodeChoice
function chooseNode(_node) {
//check each cNode to see if any are in pathArray
for (var j = 0; j < _node.cNodes.length; j++) {
//if a cNode is in pathArray, then we know to assign it nodeChoice...
if (_node.cNodes[j] in pathArray) {
nodeChoice = _node.cNodes[j];
console.log("choiceNode CORRECT: " + nodeChoice.name); //(for debugging purposes only)
}
//...otherwise don't do anything in this forLoop/ifStatement
};
//if by this point nodeChoice is still undefined, meaning none of the current node's cNodes are in pathArray, assign it any one of its cNodes.
if (nodeChoice == undefined) {
nodeChoice = _node.cNodes[Math.floor(Math.random()* _node.cNodes.length)];
console.log("choiceNode INCORRECT: " + nodeChoice.name);//(for debugging purposes only)
};
};
//Runtime:
chooseNode(nodeB);
//Result should be only nodeE.name since nodeD is not in the pathArray...
console.log(nodeChoice.name);
</script>
...however, nodeChoice is assigned either D, E or F randomly and we are given the troubleshooting statement "choiceNode INCORRECT: D (or) E (or) F", indicating that the if-in statement is always ignored. I know that the if-in statement doesn't work but am not sure how else to write it so that each cNode is compared the each element in pathArray, both of which can be of variable lengths... Hello, Could someone please help me modify this code. How can I have more then one answer correct in the fill in the blank question? For example: Green/Red is my favorite color.

Hello I need to make an answers page for a quiz but I don't know how to do it? Code is below if it helps Code:

<title>QUIZ</title>
<script>
var Q = function (id, text, correct, wrong) {
this.id = id;
this.text = text;
this.correct = correct;
this.wrong = wrong;
this.answers = this.correct.concat(this.wrong)
}
Q.prototype = {
blah: function () {
document.write("<p>x<\/p>");
},
write: function () {
if (this.asked) {
return false;
}
this.asked = true;
document.write( '<p>' + this.text + '<\/p>');
document.write( '<form>');
var type = ( this.correct.length > 1 ? "checkbox" : "radio" );
for (var i in this.answers) {
document.write( '<input type="'+type+'" name="'+this.id+'">'+this.answers[i]+'<\/input><br>');
}
document.write( '<\/form>');
return true;
}
}
var questions = [
new Q(

];
var askQuestions = function () {
var asked = 0;
while (asked < 3) {
var num = Math.floor( Math.random() * questions.length );
var question = questions[num];
if (question.write()) {
asked++;
}
}
};
askQuestions();
</script>
<BR>
<input name="Submit" type="Submit" value="How did I do?">

Any suggestions? Thanks |
