我想检测div滚动。此代码的作用是检测整个窗口滚动:
$(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;
});
}
}
});
});
这是我的 HTML 代码。
<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,但它什么也没输出,而不是两个。
最佳答案
不确定,但您可以在scroll()函数中通过id、类等引用div:
这是一个简单的jsfiddle:http://jsfiddle.net/collabcoders/v2RbN/
$(".box").scroll(function() { //.box is the class of the div
$("span").css( "display", "inline" ).fadeOut( "slow" );
});
更新:http://jsfiddle.net/collabcoders/v2RbN/1/
$("span").hide();
$(".box").scroll(function() {
if($(this).scrollTop() + $(this).innerHeight() >= $(this)[0].scrollHeight) {
$("span").show();
} else {
$("span").hide();
}
});
