我在http://www.kriesi.at/archives/create-simple-tooltips-with-css-and-jquery/comment-page-2#comment-2746有一个例子

它在样式表中创建效果并掩盖通过此函数传递的任何标记的默认工具提示

     $(document).ready(function() {


         simple_tooltip("img","tooltip"); 


        });

        function simple_tooltip(target_items, name){
        $(target_items).each(function(i){
        $("body").append("<div class='"+name+"' type='img' id='"+name+i+"'><p>"+$(this).attr('title')+"</p></div>");

        var my_tooltip = $("#"+name+i);

        $(this).removeAttr("title").mouseover(function(){
                my_tooltip.css({opacity:0.8, display:"none"}).fadeIn(400);
        }).mousemove(function(kmouse){
                my_tooltip.css({left:kmouse.pageX+15, top:kmouse.pageY+15});
        }).mouseout(function(){
                my_tooltip.fadeOut(400);
        });
    });
}

但问题是它在页面的每个图像标签上显示工具提示，因为我只想在表单验证帮助图标上显示它。这是我的表格

    <form id="form1">

        <table id="tblSignUp" border="0" cellpadding="2" cellspacing="5"
            style="border: 0px solid black; color: #FFFFFF;">
            <div id="inputs">
            <tr>
                <td>First Name<font class="AsterikLabel">*</font> :</td>
                <td><input id="firstname" size="35" maxlength="50" type="text"
                     style="width: 175px;"
                     onblur="checkError(this);" name="fname" />
                  <img  title="Alphabets, numbers and space(' ') , no special characters min 3 and max 20 characters." 
                src="PsychOImages/20.png" align="bottom" /></td>
                <td id="firstName1"></td>
            </tr>
            <tr>
                <td>Last Name<font class="AsterikLabel">*</font> :</td>
                <td><input type="text" id="lastname" style="width: 175px;"
                     name="lastname"
                     onblur="checkError(this);" />
                  <img  title="Alphabets, numbers and space(' ') , no special characters min 3 and max 20 characters." 
                    src="PsychOImages/20.png" align="bottom" />
                                                                  </td>
                <td id="lastname1"></td>
            </tr>
            <tr>
                <td>Email<font class="AsterikLabel">*</font> :</td>
                <td><input id="email" type="text" style="width: 175px;"
                     name="email"
                    onblur="checkError(this);" />
                  <img title=" The Email address format is yourname@example.com."  src="PsychOImages/20.png" align="bottom" /></td>
                <td id="email1"></td>
            </tr>
            <tr>
                <td>Telephone<font class="AsterikLabel">*</font> :</td>
                <td><input id="phone" type="text" style="width: 175px;"
                     name="phone"

$(function() {
    simple_tooltip("#form1 img", "tooltip");
});

simple_tooltip 函数的第一个参数是一个选择器，因此您可以使用它来查找您想要的任何元素。

此外，您必须删除<div id="inputs">（和相应的</div>）标签，因为您的 html 无效。您不能将div直接放在table元素内。
