仅在表单中鼠标悬停在图像上时的 JQuery 工具提示

Question

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

它创建了一个样式表中的效果并屏蔽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记上显示工具提示，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><input id="email" type="text" style="width: 175px;"

                  <img title=" The Email address format is [email protected]."  src="PsychOImages/20.png" align="bottom" /></td>
                <td id="email1"></td>

        </form>


i have tried putting my form into a div and then giving that Div id to the function
`simple_tooltip("","")`   but it stops working then.... please help!  

Answer 1

$(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所需的任何元素。

另外，您必须删除

（以及相应的

）标记，因为您的 html 无效。您不能将div直接放入table元素内。
