计划是在页面内添加一个带有加载滚动条的滚动条。2 个问题：我的加载滚动不起作用 & 我不确定是否应该使用 iframe 来实现加载滚动。主要是因为我的 div 中有一个 jQuery 可排序的、可放置的，并且不确定我是否可以拖到 iframe 之外。任何想法，将不胜感激
$(#win).scroll(function(){
//replaced window with #win, which is the id of the div containg database info
if($(this)[0].scrollTop() == $(this)[0].height()- $(this).height()){
//everytime we scroll we have this function activated
//if statement is saying if we're at the bottom of the page
//$('div#text').hide();
$('div#loadMoreComments').show();
//.show is showing the div above which has the loading animation
$.ajax({
url: "loadem.php?lastComment="+ $(".postedComment:last").attr("id"),
//using get variable to say last comment is equal to + posted
//comment which is the last comment that's displayed &
//that last comment has an id
success: function(html){
if (html){
$("#postedComment").append(html);
//if we are at the bottom we will add comments to the page
//and hide the animation
$('div#loadMoreComments').hide();
//$('div#text').show();
}else{
$('div#loadMoreComments').replaceWith("<div class='box'><center>Finished Loading</center></div>");
//if theres no more to scroll then the finished loading will show
}
}
});
}
});
