See this pull request on Github https://github.com/sstephenson/prototype/pull/93
在 Github https://github.com/sstephenson/prototype/pull/93上查看此拉取请求
PrototypeJS does some feature detection everytime it loads and Internet Explorer 10 has adjusted the way some of the Javascript syntax is parsed and throws that error.
PrototypeJS 每次加载时都会进行一些功能检测，Internet Explorer 10 已经调整了一些 Javascript 语法的解析方式并抛出该错误。
PrototypeJS is doing a detection to see how to handle passing functions as tag attributes (like an onclick method) and the IE10 javascript parser detects that as a syntax error.
PrototypeJS 正在进行检测以查看如何将传递的函数作为标记属性（如 onclick 方法）进行处理，而 IE10 javascript 解析器将其检测为语法错误。
If you look at the pull request in Github it will show you a band-aid as well as a full fix to make Internet Explorer 10 happy.
