Question

我有一部《酒吧法》,通过《联合国邮政管理处》查询一页,然后该页回来了一些在网页上展示的文本。这是我为成功做到的守则:

$.post(
    "query.php?module=vote",  
    {answer: ans, pid: pid, to: to, page: page},
    function(responseText){  
        $("#poll").html(responseText);  
    },  
    "html"  
);

I ve Trial changing $("#poll”).html(responseText) to $("#poll”).html(responseText.fadeIn(1500);,但未奏效。

我必须做些什么/做些什么才能使案文落到一页?

Answer 1

In order to fade in, the element must first be faded out. Try fading out instantly (0 seconds) then using a callback function to add the content and fade in.

$.post(
    "query.php?module=vote",  
    {answer: ans, pid: pid, to: to, page: page},
    function(responseText){  
        $("#poll").fadeOut(0,function(){
             $(this).html(responseText).fadeIn();
        }); 
    },  
    "html"  
);

Answer 2

在你能够做些事情之前,你必须确保它隐藏起来。为此:

$("#poll").html(responseText).hide().fadeIn(1500);

或者,你可以确保该元素被利用特别安全局隐藏:

#poll {
    display: none;
}

Answer 3

由于弹lement显示器具,因此首先需要fadeOut/hide。页: 1

$( #element ).fadeOut(500).html(content).fadeIn(500);
