Javascript-js tutorial

The escape (), encodeURI (), and encodeURIComponent () methods can filter out special characters that affect URL integrity. But the latter two is to convert the string to the UTF-8 to transfer, solve the problem of garbled code caused by different page encoding.

For example, if the send page is inconsistent with the Charset format of the receive page (assuming that the send page is GB2312 and the receive page is a UTF-8), use escape () the conversion and transmission of Chinese strings will cause garbled characters.
The following are various methods for URL encoding/Decoding in JS:

Escape method: the characters @ * +/A-Z 0-9 a-z are not encoded, other non-ASCII characters will be encoded with % XX encoding replacement, decoding uses unescape, the escape method cannot be used to encode the Uniform Resource Identifier (URI. Use the encodeURI and encodeURIComponent methods for encoding. EncodeURI (): Yes! @ # $ & * () = :/;? + 'A-Z 0-9 a-z, other characters will be encoded, decoding using decodeURI ();

If you want to encode more words, for example :/.., use the encodeURIComponent () method. After this method is encoded, the parameter is passed to the server as an invalid character. decodeURIComponent () is used for decoding ()
