Answer 1

可以这样做：

http://jsfiddle.net/PELkt/

var search = 'bar';
$(document).ready(function () {
    $("div:contains('"+search+"')").each(function () {
        var regex = new RegExp(search,'gi');
        $(this).html($(this).text().replace(regex, "<span class='red'>"+search+"</span>"));
    });
});

Answer 2

$("div:contains('bar')").each(function () {
    $(this).html($(this).html().replace("bar", "<span class='red'>bar</span>"));
});

这肯定会有效

您可以这样使用：

       $(document).ready(function(){
               //  $("#foo:contains('bar')").css('color','red');
               var text = 'bar' ;
               var  context = $("#foo").html();
               $("#foo").html(context.replace(text,'<span style="color:red;">'+text+'</span>'));
        });

试试这个...... prototype库：

<html> 
<head> 

    <style type="text/css">
        #content span {
            background-color: yellow;
        }
    </style>
    <script type="text/javascript" src="prototype.js"></script>
    <script type="text/javascript">
        Event.observe(window,'load',function(){
            var htm = $('content').innerHTML;
            $('content').innerHTML = htm.sub('bar','<font color=red>bar</font>');
        });
    </script>
</head>
<body>

    <div id="content">
        this is a new bar
    </div>

</body>
