Question

我一直试图让这个无限的滚动脚本在过去的8个小时内工作，并且无法弄明白。

我在这里上传了网站，以便您可以看到问题：http://kevinellerton.com/meditationmagazine/article01/当您向下滚动时，它应该加载article04，然后是03，然后是02，然后停止加载文章，因为article01已加载已经。问题是它不会停止加载它们......如果你在控制台中跟踪控制台记录的变量，它真的很不稳定。我认为问题可能与＆＃34;范围＆＃34;但我不确定： - （

如果可以，请帮忙！

非常感谢你！

$(document).ready(function() {

// DATABASE OF ARTICLES
var database = [
    "article04",
    "article03",
    "article02",
    "article01"
];



// THIS WHOLE SECTION CREATES THE INFINITE SCROLL EFFECT BY ACCESSING THE ARTICLES IN ORDER.
// IT'S NOT QUITE WORKING THOUGH.
// IF YOU FIGURE OUT THE BUGS, YOU CAN ACTIVATE INFINITE SCROLL!
// POST CODE ON STACKOVERFLOW... MAYBE YOU'LL GET SOME HELP!

// get initial page name
if (articleCounter == 0) {
    var pathArray = window.location.pathname.split('/');
    var pageName = pathArray[2];
    console.log(pageName);
}

// initialize variables
var win = $(window);
var articleCounter = 0;
console.log(articleCounter);

// Each time the user scrolls
win.scroll(function() {
    // End of the document reached?
    if ($(document).height() - win.height() == win.scrollTop()) {
        $('#loading').show();

        // if this article is the next one in the list, skip it and go to next one
        if (pageName == database[articleCounter]) {
            articleCounter++;
            var nextPage = database[articleCounter];
            pageName = nextPage;
            console.log(nextPage);
        } else {
            var nextPage = database[articleCounter];
            pageName = nextPage;
            console.log(nextPage);
        }

        // append nextPage to the end of the document
        if (nextPage !== undefined) {
            $.ajax({
                url: '../' + nextPage + '/index.php',
                dataType: 'html',
                success: function(html) {
                    $('body').append(html);
                    $('#loading').hide();
                    articleCounter++;
                        console.log(articleCounter);
                    // POSSIBLE TO CHANGE URL PATH NAME HERE???
                }
            });
        }
    }
});
});

编辑：

我今天完全重写了它，它仍然有完全相同的问题。我90％肯定这个问题与SCOPE有关，但我还没弄清楚。这是我的新代码仍无效：

$（document）.ready（function（）{

// DATABASE OF ARTICLES
var database = [
    "article04",
    "article03",
    "article02",
    "article01"
];

var articleCounter = 0;

// get initial page name
var pathArray = window.location.pathname.split('/');
var initialPage = pathArray[2];
alert("Initial page is " + initialPage);

// when you scroll
$(window).scroll(function() {
    // if you've reached the end of the document
    if ($(document).height() - $(window).height() == $(window).scrollTop()) {
        $('#loading').show();
         // if you've reached the end of the database
        if (articleCounter >= database.length) {
            // load ending footer
            alert("You've reached end of database! articleCounter is " + articleCounter);
            // quit program
        }
        else if (database[articleCounter] == initialPage) {
            articleCounter++;
            appendArticle();
            articleCounter++;
        }
        else {
            appendArticle();
            articleCounter++;
        }
    }
});

// end scroll function

function appendArticle() {
    $.ajax({
        url: '../' + database[articleCounter] + '/index.php',
        dataType: 'html',
        success: function(html) {
            $('body').append(html);
            $('#loading').hide();
            // POSSIBLE TO CHANGE URL PATH NAME HERE???
        }
    });
}

你已经在if语句中定义了变量，这是不行的，我想你的下一页和计数器的逻辑是正常的，并且你用/* */评论几乎所有的代码所以：

$(document).ready(function() {
//you will return to page beginning if no article, so you don't have to include article1

// DATABASE OF ARTICLES
var database = [
    "article04",
    "article03",
    "article02"
];



// initialize variables
var win = $(window);
var articleCounter = 0;
var loaded = true;
// Each time the user scrolls
win.scroll(function() {
    if ($(document).height() - win.height() == win.scrollTop()) {
        if(articleCounter == database.length){
            window.scrollTo(0,0);
            return;
        }

        if(!loaded) return
        $('#loading').show();
        loaded = false;
            $.ajax({
                url: '../' + database[articleCounter] + '/index.php',
                dataType: 'html',
                success: function(html) {
                    $('body').append(html);
                    $('#loading').hide();
                    articleCounter++;
                    loaded = true;
                } 
            });

    }
});


});

$(document).ready(function () {

// DATABASE OF ARTICLES
var database = [
    "article04",
    "article03",
    "article02",
    "article01"
];

var win = $(window);
ArticleLoad_Counter = database.length - 1;// Assuming that article01 is initialy loaded. ie, then we need to load remaing 3 articles.
articleCounter = 0;
var pathArray = window.location.pathname.split('/');
var pageName = pathArray[2];
console.log(pageName);

$(window).scroll(function () {
    if ($(win).scrollTop() + $(window).height() == $(document).height()) {

        // Scroll bar reached at bottom 
        alert("reached bottm");
        if (ArticleLoad_Counter != 0) {
            $('#loading').show();

            if (pageName == database[articleCounter]) {
                articleCounter++;
                nextPage = database[articleCounter];
                pageName = nextPage;
                console.log(nextPage);
                LoadNewArticle(nextPage);  // Function for Ajax Call 

            } else {
                nextPage = database[articleCounter];
                pageName = nextPage;
                console.log(nextPage);
                LoadNewArticle(nextPage); // Function for Ajax call 
            }
        }
    }
});

});

   function LoadNewArticle(nextPage) {
   $.ajax({
    url: '../' + nextPage + '/index.php',
    dataType: 'html',
    success: function (html) {
        $('body').append(html);
        $('#loading').hide();
        ArticleLoad_Counter--;
        alert(nextPage);   // Loaded article name
        console.log(articleCounter);
        // POSSIBLE TO CHANGE URL PATH NAME HERE???
     }
    });

    }

希望此代码适用于您的网站!!
