jQuery没有从按钮获取动态更新的数据 [英] jquery isn't getting dynamically updated data from button

问题描述
我创建了一个按钮,该按钮会更新其自身的值,并且再次单击时,jQuery不会选择更新后的值.
I've created a button, which updates the values of itself, and when clicked on (again), jquery isn't picking up the updated values..
在第一次单击之前:
<a href="news" data-start="2" data-limit="2" data-page="2" class="btn load-more">Load more</a>
jQuery:
$(document).on('click','.load-more',function(e){
e.preventDefault();
var start = $(this).data('start'),
limit = $(this).data('limit'),
page = $(this).data('page'),
type = $(this).attr('href');
alert( start+' '+limit+' '+page );
$.ajax({
url:'/index.php?route=news/news/getnext&start=4&limit=4&page=2',
method:'GET',
data:{start:start,limit:limit,page:page},
dataType:'json',
success:function(data){
.... doing stuff ....
if(data.pagination === true){
$('.load-more').attr('data-start',data.start).attr('data-limit',data.limit).attr('data-page',data.next);
} else {
$('.load-more').fadeOut(250,function(){
$(this).remove();
});
}
}
})(data);
});
这将按预期发出"2 2 2"警报.
This alerts "2 2 2" as expected.
更新后的按钮(第一次单击后):
The updated button (after the first click):
<a href="news" data-start="4" data-limit="2" data-page="3" class="btn load-more">Load more</a>
然后,我再次单击该按钮,它仍然提示按钮已更新为"2 2 2",而不是"4 2 3".
Then I click the button again, and it still alerts "2 2 2", instead of "4 2 3", which the button was updated to..
对此有何想法?我似乎无法正常工作,我已经尝试了基本的click函数并进行了委派,但是它没有按预期工作.
Any ideas on this? I can't seem to get it working, I've tried the basic click function and also delegate but it's not working as expected.
推荐答案
更新以下代码后:
<a href="news" data-start="4" data-limit="2" data-page="3" class="btn load-more">Load more</a>
$(document).on('click','.load-more',function(e){
e.preventDefault();
var start = $(this).attr('data-start');
limit = $(this).attr('data-limit');
page = $(this).attr('data-page');
alert( start+' '+limit+' '+page );
});
