最近对wordpress的一些小改进很感兴趣，可以让你的博客更加个性，也更有趣味性，下面的代码可以在结果中高亮你所搜索的关键词。首先把第一段代码放在functions.php中：

function hls_set_query() {

$query = attribute_escape(get_search_query());

if(strlen($query) > 0){

echo '

<script type="text/javascript">

var hls_query = "'.$query.'";

</script>

';

}

}

function hls_init_jquery() {

wp_enqueue_script('jquery');

}

add_action('init', 'hls_init_jquery');

add_action('wp_print_scripts', 'hls_set_query');然后把下面的代码放在header.php中，就OK了。

<style type="text/css" media="screen">

.hls { background: #D3E18A; }

</style>

<script type="text/javascript">

jQuery.fn.extend({

highlight: function(search, insensitive, hls_class){

var regex = new RegExp("(<[^>]*>)|(b"+ search.replace(/([-.*+?^${}()|[]/])/g,"$1") +")", insensitive ? "ig" : "g");

return this.html(this.html().replace(regex, function(a, b, c){

return (a.charAt(0) == "<") ? a : "<strong+ hls_class +"">" + c + "</strong>";

}));

}

});

jQuery(document).ready(function($){

if(typeof(hls_query) != 'undefined'){

$("#post-area").highlight(hls_query, 1, "hls");

}

});

</script>
