URL编码/解码
编码和解码URL组件和查询字符串参数
Client-side only — uses native browser encodeURIComponent / decodeURIComponent (RFC 3986). Your data never leaves the browser.

FAQ
What is URL encoding?
URL encoding replaces unsafe ASCII characters with % followed by two hex digits. A space becomes %20, & becomes %26.
When do I need to URL encode?
When passing special characters in query parameters or form data. Unencoded characters like #, &, and = break the URL.
encodeURI vs encodeURIComponent?
encodeURI encodes a full URL and leaves /, ?, # intact. encodeURIComponent encodes a single value and escapes those characters too — use it for query string values.
