这里 div 内的整个文本都变成红色。但我只需要改变“bar”字的颜色
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title> new document </title>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#foo:contains('bar')").css('color','red');
});
</script>
</head>
<body>
<div id="foo">
this is a new bar
</div>
</body>
</html>
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>"));
});
});
