我想检测div滚动.这个代码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,但是它不输出两个.
解决方法
不确定,但是你可以在scroll()函数中通过id,class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();
}
});
