How to get a score in javascript

[phil74801]

Hi everybody,

Thanks to a user, I have got  this exemple. I used it to do a quiz. A user answers  this quiz and you will be given his score. In this exemple he must get the different languages in the good order (for instance: Russian, French, English, and Italian). So far it works, but I don't know how to do the javascript to obtain the score.

Script of the button (click_event):

for (var i = 0; i < ListBox1.length; i++)

{

    if (ListBox1.getItemState(i))

    {

        ListBox2.addItem(ListBox1.getDisplayItem(i), ListBox1.getSaveItem(i));

    }

}

for (var i = ListBox1.length; i >= 0; i--)

{

    if (ListBox1.getItemState(i))

    {

        ListBox1.deleteItem(i);

    }

}

Script of the listbox (change_event)

for (var i = 0; i < this.items.nodes.length; i++)

{

    if (xfa.event.change == this.items.nodes.item(i).value)

    {

        XFAUtil.setProperty(this, "selectedIndex", i, XFAUtil.ContentType.Integer);

        break;

    }

}

Script of the total box (?_event)

Now it's your turn!

Any help will be appreciated

Many thanks

I'm not exactly sure how you'd want to score the languages. Something like, if they're in alphabetical order, the user gets 4 points for the first answer, 3 for the second, etc. Or if they're all in the correct order, then the user gets 10 points. Or the user is answering how many lnguages he speaks, and gets 1 point for one language, 2 points for two languages, etc. So, here's some examples.

Script for calculate event of total box:

//to give a score based on alpabetical order individually

this.rawValue = 0;

if (ListBox2.getDisplayItem(0) == "English") this.rawValue = parseInt(this.rawValue) + 4;

if (ListBox2.getDisplayItem(1) == "French") this.rawValue = parseInt(this.rawValue) + 3;

if (ListBox2.getDisplayItem(2) == "Italian") this.rawValue = parseInt(this.rawValue) + 2;

if (ListBox2.getDisplayItem(3) == "Russian") this.rawValue = parseInt(this.rawValue) + 1;

or

//to give a score based on alphabetical order if all correct

this.rawValue = 0;

if (ListBox2.length == 4 && ListBox2.getDisplayItem(0) == "English" && ListBox2.getDisplayItem(1) == "French" && ListBox2.getDisplayItem(2) == "Italian") this.rawValue = 10;

or

//to give a score based on number of languages spoken, 1, 3, 6, 10 pts.

this.rawValue = 0;

for (var i = 0; i<ListBox2.length; i++) this.rawValue = parseInt(this.rawValue) + i + 1;

Hopefully, those examples cover what kind of scoring you might want to do.

  Euh ! One more question !

If the user is mistaken or if he wants to do again the quiz, is it possible to delete the content of the ListBox2 with the reset Button but without selecting all answers ?

Thanks

Basically you want a "reset" button, right? Do you care if the list is in a different order? I.e., can the "reset" button just move everything back over to the first box regardless of order? If so,

for (var i = 0; i < ListBox2.length; i++) ListBox1.addItem(ListBox2.getDisplayItem(i));

for (var i = ListBox2.length; i>= 0; i--) ListBox2.deleteItem(i);

What more could I ask for?

Thanks a million !
