中的冒号"div:.userMenu"不正确，jquery 无法识别。如果你想<div>用userMenu类全选，语法是

$("div.userMenu",this );

完整脚本：

<script type="text/javascript">
$(function(){
    $(".user_ava").click(function() {
        $("div.userMenu",this ).animate({ // you had a colon here for some reason
            height: ["toggle", "swing"],
            opacity: "toggle"
        }, 200, "linear");
    });
});
</script>

删除“div:.userMenu”中的“:”

<script type="text/javascript">
$(function(){
    $(".user_ava").click(function() {
        $("div.userMenu",this ).animate({
            height: ["toggle", "swing"],
            opacity: "toggle"
        }, 200, "linear");
    });
});
</script>
