语法检查是通过加载 http://www.learneroo.com/assets/ace-src/worker-javascript。 js 文件，但在您的网站中该文件似乎是空的。我只在其中看到; 。

在之前显示的jsfiddle http://jsbin.com/ojijeb/432/edit ，由于对网络工作者的交叉原始限制（因为运行chrome时我没注意到）所以它无效使用 - disable-web-security ），但是由于最新的Ace更新，它现在可以使用。

Syntax checking is done via webworker which loads http://www.learneroo.com/assets/ace-src/worker-javascript.js file, but in your site that file seems to be empty. I only see ; in it.
In the jsfiddle i showed earlier http://jsbin.com/ojijeb/432/edit, it didn't work because of cross origin restrictions on web workers (which i didn't notice since was running chrome with --disable-web-security), but thanks to latest Ace update, it works now.
