我想檢測div滾動。此代碼所做的是檢測整個窗口滾動:檢測div滾動jquery
$(document).ready(function() {
var track_load = 0; //total loaded record group(s)
var loading = false; //to prevents multipal ajax loads
var total_groups = <?php echo $total_groups; ?>; //total record group(s)
$('#results').load("autoload_process.php", {'group_no':track_load}, function() {track_load++;}); //load first group
$(window).scroll(function() { //detect page scroll
if($(window).scrollTop() + $(window).height() == $(document).height()) //user scrolled to bottom of the page?
{
if(track_load <= total_groups && loading==false) //there's more data to load
{
loading = true; //prevent further ajax loading
$('.animation_image').show(); //show loading image
//load data from the server using a HTTP POST request
$.post('autoload_process.php',{'group_no': track_load}, function(data){
$("#results").append(data); //append received data into the element
//hide loading image
$('.animation_image').hide(); //hide loading image once data is received
track_load++; //loaded group increment
loading = false;
}).fail(function(xhr, ajaxOptions, thrownError) { //any errors?
alert(thrownError); //alert with HTTP error
$('.animation_image').hide(); //hide loading image
loading = false;
});
}
}
});
});
這是我的HTML代碼。
<div id="scrollingbox">
<ol id="results">
</ol>
<div class="animation_image" style="display:none" align="center"><img src="ajax-loader.gif"></div>
</div>
我使用了div ID,但它不輸出任何內容,而是輸出任何內容。
我修改了我的問題先生,看看http://stackoverflow.com/questions/21212051/jquery-find-if-div-reached-the-bottom-on-scroll – user3196424
