我有这个表达:

$('#animationNext,#animationPrev').bind('mousedown',function(){        
    $('.nInfoIE').show();
    $('ul.roundabout-holder li').find('.iframe').css({'visibility':'hidden'});
    $('ul.roundabout-holder li').find('.iframe').addClass('esconder');

    // more code...

    watching = false;
    $('.nInfoIE').hide();
});

请注意我在问题中删除了许多表达式。

情况是这在所有浏览器中都很好用,但在 IE6 中它需要 10 倍 loger 才能执行(我说的是 7 秒左右!)所以我试图<div class="nInfoIE">在开始时显示(包含一个 loding 图像)和最后把它藏起来,

但似乎它都是同时执行的,因为我永远看不到nInfoIe的内容,

我如何确保我会在之前看到它,然后执行其余的?

我只能假设“更多代码”部分适用于一个或多个 ajax 请求。ajax 请求被触发后,即使 ajax 请求尚未完成,也会处理下一个表达式。您应该在 ajax 请求的完成事件中隐藏加载图像。

$.ajax({
  type: 'POST',
  url: url,
  data: data,
  success: success,
  complete: function() { watching = false;
                    $('nInfoIE').hide(); }
});

如果有多个 ajax 请求,它会变得有点复杂,你必须嵌套它们或使用某种 ajax 队列管理器。

好吧,您提供了代码,但我看不到任何类名为“nInfoIE”的元素,这在这里有点相关。

但是,我确实注意到了您的选择器:

$('nInfoIE').show();

由于您试图通过类名获取元素,因此您必须指定“。” 在它面前。它应该是

$('.nInfoIE').show();
