我向页面添加了无限滚动，现在每次为无限滚动加载更多结果时，页面都会从页面顶部复制内容。
页面加载如下：
- 广告
- 赞助内容
- 广告
- 无限滚动表的前 9 个结果
当页面到达无限滚动的末尾时，就会发生这种情况
- 广告重播
- 赞助内容重复
- 广告重复
- 表格中的下 9 行按需要显示。
我想知道如何阻止广告和赞助内容随着我的无限滚动而重复。
这是我用于无限滚动的脚本：
// Loading news
var pageLoad = 1;
var totalPages = 1;
/* This is function which is called to load news. The input parameter is page, a variable which assumes number of active page. Default is 1 */
function loadingNews(page){
$('#events').append('<div class="loader-div"><img src="" class="img img-responsive img-loader" /></div>');
$.ajax({
type: "GET",
url: "websitephppagebelow.php",
method: "POST",
dataType: "json",
data: {'eventuser': '0', 'page': page},
success: function (data) {
$(".loader-div").remove('.loader-div');
$('#events').append(data.deals);
totalPages = data.totalPages;
},
error: function (jqXHR, exception) {
var msg = '';
if (jqXHR.status === 0) {
msg = 'Not connect.\n Verify Network.';
} else if (jqXHR.status == 404) {
msg = 'Requested page not found. [404]';
} else if (jqXHR.status == 500) {
msg = 'Internal Server Error [500].';
} else if (exception === 'parsererror') {
msg = 'Requested JSON parse failed.';
} else if (exception === 'timeout') {
msg = 'Time out error.';
} else if (exception === 'abort') {
msg = 'Ajax request aborted.';
} else {
msg = 'Uncaught Error.\n' + jqXHR.responseText;
}
console.log(jqXHR);
}
});
}
/* Here the function for page loading is calling. The input parameter (pageLoad) is variable which constantly is updating. */
loadingNews(pageLoad);
/* This is the function which "listen" scrolling on the page. If it reaches the bottom of the page, sends new call to loadingNews function. */
var win = $(window);
win.scroll(function(){
if ($(document).height() - win.height() == win.scrollTop()) {
pageLoad++;
// console.log("page load: " + pageLoad + "; total: " + totalPages);
if(pageLoad <= totalPages) {
loadingNews(pageLoad);
}else{
pageLoad--;
}
}
});
});
这是我用于无限滚动的 php：
