不知道具体修改什么代码。。
header.php 里面有这个
<form action="
http://www.google.com/cse" id="cse-search-box" target="_blank">
<input type="hidden" name="cx" value="001242549033659596683:stdixwi7uw0" />
<input type="hidden" name="ie" value="UTF-8" />
<input type="text" name="q" id="s" />
<input type="image" name="sa" id="searchsubmit" src="<?php bloginfo('template_directory'); ?>/images/s_btn.jpg" onmouseover="this.src='<?php bloginfo('template_directory'); ?>/images/s_btn2.jpg'" onmouseout="this.src='<?php bloginfo('template_directory'); ?>/images/s_btn.jpg'"/>
</form>
