用於按時間順序顯示和隱藏div的JavaScript

Question

我在使代碼正常工作方面遇到問題。 我知道我已經問過幾次這個問題，但是我確實需要一些投入。 多虧了該站點上的某人，我才能夠使代碼在jsFiddle中工作，但無法在我的瀏覽器中工作。

任何我做錯事的想法嗎？

的HTML

<div class="fader tutorial" id="createquestion1">
    <div class="arrow-w" style="font-size:1em;"></div>
    &nbsp;Start by creating a title and selecting a folder for your question to be stored in.
</div>

<div class="fader tutorial" id="createquestion2">
    <div class="arrow-w" style="font-size:1em;"></div>
    &nbsp;Categories are key to your reporting effectiveness, be sure to include categories that relate to this question.
</div>

<div class="fader tutorial" id="createquestion3">
    <div class="arrow-w" style="font-size:1em;"></div>
    &nbsp;Select your options and/or upload an attachment (file, video or audio).
</div>

<div class="fader tutorial" id="createquestion4">
    <div class="arrow-w" style="font-size:1em;"></div>
   To create questions easier update your question preferences in your account area options.&nbsp
</div>

<div class="fader tutorial" id="createquestion5">
    <div class="arrow-w" style="font-size:1em;"></div>
    &nbsp;Your rationale can be used to provide feedback to students on this question and you also can use internal comment to track notes on changes, updates, textbook information and more.
</div>

<div class="fader tutorial" id="createquestion6">
    <div class="arrow-w" style="font-size:1em;"></div>
   Write your questions, answers and you are ready to go.&nbsp;
</div>

<input type="button" value="Start" id="start"/>

JS

function fadeLoop() {

    var counter = 0,
        divs = $('.fader').hide(),
        dur = 500;

    function showDiv() {
        divs.fadeOut(dur) // hide all divs
            .filter(function(index) {
                return index == counter % divs.length;
            }) // figure out correct div to show
            .delay(dur) // delay until fadeout is finished
            .fadeIn(dur); // and show it
        counter++;
    }; // function to loop through divs and show correct div
    showDiv(); // show first div    
    return setInterval(function() {
        showDiv(); // show next div
    }, 5 * 1000); // do this every 5 seconds     };

$(function() {
    var interval;

    $("#start").click(function() {
        if (interval == undefined){
            interval = fadeLoop();
            $(this).val("Stop");
        }
        else{
            clearInterval(interval);
            $(this).val("Start");
            interval = undefined;
        }
    }); });​

有很多可以幫助我的人！ 我正在工作的頁面是ASP。 我也樂於接受新想法。 理想情況下，我希望完全在CSS3中做到這一點...
