javascript - 关于 fis3 写插件出现的问题-PHP中文网问答

//fis-conf.js
fis.match("*.html",{
    preprocessor:function(content,file){
        return content+='<pre>'+content+'</pre>';
    }
})
/*目的是想匹配html文件里面的
“<script type="text/javascript" src="index.js" data-use="init"></script>”
这段代码，做sea.use()调用的处理，
上面的代码只是试一试 content 的内容是什么，
结果conten里面并没有
<script type="text/javascript" src="index.js" data-use="init"></script> */

html文件代码是这样的

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

      </p>
    </p>

</html></pre>
