使用fadeIn()附加html淡入淡出

Question

我不能得到<li>附加到我的元素$('ul#posts')淡入.

我试过的事情.

1. 在淡入之前设置display:noneof <li>.在请求之后无法查看附加的html.这意味着fadeIn()没有用.

2. $(wall_post).appendTo('ul#posts').fadeIn("slow"); 似乎也没有用.

码:

var wall_post = '<li> <img src="image/avatar.jpg" class="avatar"><div class="status"><h2><a href="#" target="_blank">disran</a></h2><p class="message">' + textarea_content + '</p> ' + image_html + '<div class="data"><p class="name"><a href="' + siteurl + '" target="_blank">' + sitetitle + '</a></p><p class="caption">' + siteurl + '</p><p class="description">' + sitedesc + '</p></div></div> </div><p class="likes">5 hours ago · 100 Likes </p></li>';

var message_wall = $('#message_wall').attr('value');

$.ajax({
    type: "GET",
    url: "insert.php",
    data: "message_wall=" + wall_post,
    success: function () {
        //$('ul#posts').append(wall_post).fadeIn('slow');
        //$(wall_post).appendTo('ul#posts').fadeIn("slow");
        $('ul#posts').append(wall_post).fadeIn('slow');
    }
});

wall_post HTML结构

<li>
    <img src="image/avatar.jpg" class="avatar">
    <div class="status">
        <h2><a href="#" target="_blank">disran</a></h2>
        <p class="message">[.. textarea_content ..]</p> 
        [.. image_html ..]
        <div class="data">
            <p class="name">
                <a href="[.. siteurl ..]" target="_blank">[.. sitetitle ..]</a>
            </p>
            <p class="caption">[.. siteurl ..]</p>
            <p class="description">[.. sitedesc ..]</p>
        </div>
    </div>
    <p class="likes">5 hours ago 100 Likes</p>
</li>

你现在正在使用一个字符串来处理,总是工作..所以我应该做的是使它成为这样的对象:

var wall_post = $('<li>[.. rest of html structure ..]</li>');
var message_wall = $('#message_wall').attr('value');

$.ajax({
    type: "GET",
    url: "insert.php",
    // why are you sending the wallpost?? why getting you HTML from PHP?? 
    // but i think its the message_wall variable you ment?
    data: "message_wall=" + wall_post,
    success: function () {
        $('ul#posts').append(wall_post)
        wall_post.hide(); // instant hide the wall_post
        wall_post.fadeIn('slow'); // let is fadein slow
    }
});
