Nexting Code

fs22 · October 13th, 2004, 03:19 PM

I have a page that someone else developed and it has a problem with the navigation. First, here is the pertinent code...

// create array of all quiz pages in the entire quiz
var quiz = new Array()

quiz[0] = new quizPage("intro_home.htm")
quiz[1] = new quizPage("intro_q1.htm")
quiz[2] = new quizPage("intro_q2.htm")
quiz[3] = new quizPage("intro_q3.htm")
quiz[4] = new quizPage("intro_q4.htm")
quiz[5] = new quizPage("intro_q5.htm")
quiz[6] = new quizPage("intro_q6.htm")
quiz[7] = new quizPage("intro_q7.htm")
quiz

= new quizPage("intro_q8.htm")
quiz[9] = new quizPage("intro_q9.htm")
quiz[10] = new quizPage("intro_q10.htm")
quiz[11] = new quizPage("intro_sum.htm")

// navigate to next quiz page in sequence
function goNext() {
  var currPage, i
  for (i=0; i<(quiz.length-1); i++)
  {
    if (parent.main.location.href.indexOf(quiz[i].src) != -1)
    {
      parent.main.location.href = quiz[i+1].src
      break
    }
  }
}

Problem is that when the intro_sum.htm page is displayed and the end user clicks on the next button (which kicks the gonext function into action), they get an error because parent.main.location.href is undefined. I tried simply putting a new line into the array to fix it, but that did not work and I even tried changing the if statement to an if else statement. Anyone have any ideas?

Thanks in advance for your assistance.

Has anyone read this and had thoughts that would help?

Hi Clay,

By the look of it you are trying to reference an element outside of the array - when "intro_sum.htm" is the page in main you are referencing quiz[11 + 1].

What do you want to happen when someone clicks next on "intro_sum.htm"?

Cheers,

Chris

Chris,

thanks for the assist. All I want to be able to do is to send the user to a menu page and replace this frameset. Thoughts?

Hi Clay,

Something like this should work...

Code:

function goNext() {
    var currPage, i
    for (i=0; i<(quiz.length-1); i++) 
    {
        if (parent.main.location.href.indexOf(quiz[i].src) != -1) 
        {
            if(i + 1 == quiz.length){
                top.location.href = "myMenuPage.htm";
            }else{
                parent.main.location.href = quiz[i+1].src
                break
            }    
        }
    }
}

HTH,

Chris

Chris I see what you are trying to do and I tried something similiar. I also tried it the way you have it coded and I still get an error. It is telling me that parent.main.location.href is null or not an object. WHat do you think?

Try referencing the main frame with:

top.frames.main
or
parent.frames.main

Instead of:

parent.main

Also, make sure the name of the frame is "main", case sensitive.

This may or may not solve your problem. Let me know.

Try new FreshView 0.2!
There are only two stupid questions: the one you don't ask, and the one you ask more than once ;)

Hi Clay,

This works for me in IE & Mozilla...

frameset

Code:

<html>

<head>
<title></title>
</head>

<frameset cols="200, *">
    <frame name="nav" src="nav.htm"></frame>
    <frame name="main" src="intro_sum.htm"></frame>
</frameset>

</html>

nav.htm

Code:

<html>

<head>
<title></title>
<script type="text/javascript">
// create array of all quiz pages in the entire quiz
var quiz = new Array()

quiz[0] = new quizPage("intro_home.htm")
quiz[1] = new quizPage("intro_q1.htm")
quiz[2] = new quizPage("intro_q2.htm")
quiz[3] = new quizPage("intro_q3.htm")
quiz[4] = new quizPage("intro_q4.htm")
quiz[5] = new quizPage("intro_q5.htm")
quiz[6] = new quizPage("intro_q6.htm")
quiz[7] = new quizPage("intro_q7.htm")
quiz[8] = new quizPage("intro_q8.htm")
quiz[9] = new quizPage("intro_q9.htm")
quiz[10] = new quizPage("intro_q10.htm")
quiz[11] = new quizPage("intro_sum.htm")

// navigate to next quiz page in sequence
function goNext() {
    var currPage, i
    for(i = 0; i < quiz.length; i++) // was i<(quiz.length-1); 
    {
        if (parent.main.location.href.indexOf(quiz[i].src) != -1) 
        {
            if(i + 1 == quiz.length){
                top.location.href = "myMenuPage.htm";        
            }else{
                parent.main.location.href = quiz[i+1].src;
            }
            break
        }
    }
}

function quizPage(src){
    this.src = src;
}

</script>
</head>

<body>

</body>

</html>

intro_sum.htm

Code:

<html>

<head>
<title></title>
</head>

<body>

<input type="button" onclick="parent.nav.goNext();" value="goNext();" />

</body>

</html>

BTW, why do you keep re-posting the last post as a quote?

HTH,

Chris

Chris,

Thanks for the code suggestion, but it did not work. It is still telling me that parent.main.location.href is null or not an object. Any other thoughts?

As for why it quotes, this message board does that when you reply to a message as opposed to the topic.
