浏览一些网站我读到IE7不支持indexOf。这是正确的，如果是这样，最简单的方法是检查字符串是否包含给定的字符串？

推荐答案
据我所知， Array.indexOf 不受支持，但是 String.indexOf ，根据你上面的例子，是。
As far as I'm aware, Array.indexOf isn't supported, however String.indexOf, as per your example above, is.
这样的事情最好的办法out只是在您查询的浏览器中尝试它们。这比询问别人，人们有不同的浏览器配置等更可靠。
The best way to work things like this out are to just try them in the browser you're querying. This is much more reliable than asking someone else, people have different browser configurations etc.
更新：参见这个MSDN文档页面，自IE6以来一直受支持。
Update: See this MSDN documentation page about indexOf, it's been supported since IE6.
