Http://www.jb51.net/article/14657.htm JS has 3 functions for text encoding: escape,encodeuri,encodeuricomponent, corresponding decoding function: Unescape, Decodeuri,decodeuricomponent 1, escape to encode characters other than ANSI code 0-255 output%u**** format is the Unicode value, the Escape method returns a string value (in Unicode format) that contains the contents of the charstring. All spaces, punctuation, accent marks, and other non-ASCII characters are replaced with%XX encoding, where xx equals the hexadecimal number that represents the character. For example, a space returns "%20"
Escape does not encode characters with 69: *,+,-,.,/,@,_,0-9,a-z,a-z
2. encodeURI similar to escape for address bar coding
encodeURI does not encode 82 characters:!,#,$,&, ', (,), *,+,,,-,.,/,:,;,=,?,@,_,~,0-9,a-z,a-z
3, encodeURIComponent for address bar coding. Encodes a text string as a valid component of a Uniform Resource Identifier (URI). It is the Chinese, Korean and other special characters into the utf-8 format of the URL encoding, if your page encoding is gb2312, the server side will be garbled.
encodeURIComponent does not encode 71 characters:!, ', (,), *,-,.,_,~,0-9,a-z,a-z
So JS using the data can use escape, for the address bar data, it is best to use encodeuricomponent encoding.do not understand the function can be searched!
