After browsing some sites I read that IE7 doesnt support indexOf. Is this correct, and if so, whats the easiest way to check if a string contains a given string?
浏览一些网站后，我读到 IE7 不支持 indexOf。这是正确的，如果是，检查字符串是否包含给定字符串的最简单方法是什么？
var test = window.location.toString();
test = test.toLowerCase();
var idString = "28A3CASDGAGHTSDASF34134";
idString = idString.toLowerCase();
if(test.indexOf(idString) > 0){
alert('worked');
}
Edit: Most likely some coding error by myself

As far as I'm aware, Array.indexOfisn't supported, however String.indexOf, as per your example above, is.
据我所知，Array.indexOf不支持，但是String.indexOf，根据您上面的示例，是。
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.
解决此类问题的最佳方法是在您查询的浏览器中尝试它们。这比询问其他人可靠得多，人们有不同的浏览器配置等。
Update: See this MSDN documentation pageabout indexOf, it's been supported since IE6.
更新：请参阅有关 indexOf 的MSDN 文档页面，自 IE6 起就支持它。
