A JavaScript Quiz - Randomize so the second result isn't the same

a4jp_com

I usually program in ActionScript and haven't worked with any JavaScript for a really long time. So I have pasted a few chunks of code together and would like to get a bit of help if it is all right. I'm making a very simple quiz and need a bit of help with a few things.

The first thing is making sure when the code is randomized that just the first result doesn't get repeated twice.

The second thing is when I push the enter button the quiz says correct when an answer is correct but I want it to ask another question instead.

Any help is greatly appreciated.

function doSet(){  // this prepares the question
	 var score, prompting, answer, txt;
   offset = Math.floor(Math.random()*(question.length + 1));  //get the random number

   if(offset >= question.length){  // make sure its not out of range
       doSet();
       return;
   }

   score = document.getElementById('score');  //here we kill off the old text and enter in the new for the question
   score.removeChild(score.firstChild);
   txt = document.createTextNode('A4JP.com: What is the answer for:');
   score.appendChild(txt);
   prompting = document.getElementById('prompting'); //put the word to be translated into the 'prompting' div
   prompting.removeChild(prompting.firstChild);
   txt = document.createTextNode(english[offset]);
   prompting.appendChild(txt);
   answer = document.getElementById('answer'); // empty out the text field  to make it blank
   answer.value = '';
}


function doCheck(){  // this checks the answer
   var x, y, score, txt;
   score = document.getElementById('score');
   score.removeChild(score.firstChild); // empty the 'score' div
   x= document.getElementById('answer');//read the value in the text input box
   if(x.value == question[offset]){  //react to the user input
		 txt = "Correct!";
		}
   else{
     txt = question[offset];
		    }
   txt = document.createTextNode(txt);
   score.appendChild(txt);  // display the output
}

function doClick(e){
            var key;

        if(window.event)
                 key = window.event.keyCode;      //IE
        else
                 key = e.which;      //firefox

        if (key == 13)
        {
             doCheck();
        }
}

Okay. Where are the signature settings? Also where is the second message I sent? I thought saying this code was to help people study Japanese was ok. I've been working on the databade for a while now and would like to help people.

I don't understand why I can't I say my real name here. That is weird. Is this forum filled with people doing illegal stuff or something? Please let me write my name. Otherwise how can I search for my posts on the internet???

a4jp_com

I looked in user cp there aren't any signature settings.

Can someone help with the code to get the next question working when I press enter please?

if (key == 13)
            {
                 some function name here ();
            }

function doCheck(){  // this checks the answer
   var x, y, score, txt;
   score = document.getElementById('score');
   score.removeChild(score.firstChild); // empty the 'score' div
   x= document.getElementById('answer');//read the value in the text input box
   if(x.value == question[offset]){  //react to the user input
		 txt = "Correct!";
something here instead of say correct
		}
   else{
     txt = question[offset];
		    }
   txt = document.createTextNode(txt);
   score.appendChild(txt);  // display the output
}

window.onload = function(){
  //here is where you load in the data by using the dL function--you can add more word pairs as time permits
  dL('a4jp', 'design');
  dL('agreatdream', 'study);

  doSet();
}

I moved the code that displays the result in the score text field. That way it is easier to get rid of the "Correct!" text.

function doCheck(){  // this checks the answer
   var x, y, score, txt;
   score = document.getElementById('score');
   score.removeChild(score.firstChild); // empty the 'score' div
   x= document.getElementById('answer');//read the value in the text input box
   if(x.value == question[offset]){  //react to the user input
		 txt = "Correct!";
		 txt = document.createTextNode(txt);
   	 score.appendChild(txt);  // display the output

	}
   else{
     txt = question[offset];
		 txt = document.createTextNode(txt);
     score.appendChild(txt);  // display the output
   }

}

For some reason the box would just dissapear and the code stopped working before... Maybe I made a small mistake somewhere...

I figured out how to get the enter button working properly I just made a silly typing mistake :rolleyes:

It looks like there are lots of people using webdeveloper.com but I just want to see if anyone is really here

Hello Nice to meet you all.

Here's a more difficult problem for all those super smart people

How do I set the text in a text field to Hiragana (Japanese) only? I haven't found an examples of working code yet but I found this:

String.prototype.isHiragana

Thank you.

I don't work with unicode that much but if you want to limit a string to only showing japanese, then i'd look at a regex that filters all non-hiragana/katakana characters. For that i'd look here:

Edit: Just in case its not obvious, i believe japanese fits into the ideographic unicode space category.

Thank you for your advice Jarrod1937

I know I can set the focus of a text field with an id, by using code like this:

answer.focus();

"answer" is the id of the input area.

But how do I set the string prototype? The code below doesn't work but it is probably close...

answer = String.prototype.isHiragana;

Do I have to make a function?

String.prototype.isHiragana = function(){
something;
}

Can someone please help me?

I would love to find out how to set the the input language also character type to Hiragana.

I know people using English don't really do this type of thing, so it is difficult to find information about doing it.

Ok. Maybe I'll give up on trying to get the text box working in Japanese for now.

Can someone help me make a for loop to replace the random code?

var qnumber;

function makenumber(){
   for(i=0;i<question.length;i++)
		{
		 var qnumber = i;
		}
}

function doSet(){  // this prepares the question
	 var score, prompting, answer, txt;
   /*offset = Math.floor(Math.random()*(question.length + 1));  //get the random number*/

	makenumber();
	offset = qnumber;

etc...

I know this doesn't work but it is probably close.

The random code works but I would like to loop through the list instead of just picking a random number. Sometimes the same questions are repeated with the random code.

Regards,

Glen

I've pretty much figured out everything. I just need to find out how to set the language of the keyboard and randomize the array.

JavaScript is kind of like ActionScript in a way
