I have an array filled with strings, a value can for example be "not updated for > days". I use the values in the array to create some url's and need to remove the /\<> and other illegal URL characters. How do I easiest do this?
我有一个填充字符串的数组，例如一个值可以是“未更新 > 天”。我使用数组中的值来创建一些 url，并需要删除 /\<> 和其他非法 URL 字符。我如何最简单地做到这一点？
I started with
我开始了
var Name0 = title[0].substring(1).replace(" ", "%20").replace("/", "") + '.aspx';
var Name1 = title[1].substring(1).replace(" ", "%20").replace("/", "") + '.aspx';
and so on but can I do this in a better way?
Thanks in advance.

If you wish to keep the symbols in the URI, but encode them:
如果您希望将符号保留在 URI 中，但对其进行编码：
encodedURI = encodeURIComponent(crappyURI);
If you wish to build 'friendly' URIs such as those on blogs:
如果您希望构建“友好”的 URI，例如博客上的 URI：
niceURI = crappyURI.replace(/[^a-zA-Z0-9-_]/g, '');
