JS encoding/decoding of URL strings

Although escape (), encodeURI (), and encodeURIComponent () Three methods can be used to affect the URL integrity of a number of special
characters for filtering. But the latter two is to convert the string to UTF-8 way to transfer, resolved the page encoding mixed to cause the garbled question
Problem. For example, the Send page is inconsistent with the encoding format (Charset) of the Accept page (assuming that the sending page is GB2312 and the Receive page encoding is
UTF-8), using Escape () to convert the text string in the transmission will cause garbled problems.
Here are the various ways to encode/decode URLs under JS:
Escape method: Returns an encoded String object that can be read on all computers.
function Escape (charstring:string): String
Characters that are not encoded by this method: @ */+
Description: The Escape method returns a string value (in Unicode format) that contains charstring content. All spaces, punctuation,
Accented symbols and any other non-ASCII characters are replaced with%XX encoding, where xx equals the hexadecimal number that represents the character.
For example, a space is returned as "%20". (characters with a character value greater than 255 are stored in%uxxxx format.) ）
Note: The escape method cannot be used to encode a Uniform Resource Identifier (URI). The encoding should use the encodeURI and
encodeURIComponent method.
encodeURI method: Returns a string encoded as a valid Uniform Resource Identifier (URI).
function encodeURI (uristring:string): String
Characters that will not be encoded by this method:! @ # $ & * () =:/;? +
Description: The encodeURI method returns an encoded URI. If the encoding result is passed to decodeURI, the initial
String. encodeURI does not encode the following characters: ":", "/", ";" and "?". Please use
These characters are encoded by the encodeuricomponent.
encodeURIComponent method: Returns a string of valid components encoded as a Uniform Resource Identifier (URI).
function encodeURIComponent (encodeduristring:string): String
Characters that will not be encoded by this method:! * ( ) ‘
Description: The encodeURIComponent method returns an encoded URI. If you pass the encoding result to the
decodeURIComponent, the initial string is returned. Because the encodeURIComponent method encodes all characters,
Note that if the string represents a path, such as/folder1/folder2/default.html, the slash will also be
encoding, so that it will be invalid when the string is sent as a request to the WEB server. If the string contains more than one URI
component, use the encodeURI method to encode.
Unescape method: Returns the decoded string from a string object encoded with the escape method.
function unescape (charstring:string): String
Description: The Unescape method returns a string value that contains the contents of the charstring. All encoded in%XX 16 binary form
Characters are replaced by the equivalent characters in the ASCII character set. (characters encoded in%uxxxx format (Unicode characters) with 16
The Unicode character of the binary code xxxx is replaced. ）
Note: The Unescape method should not be used to decode the Uniform Resource Identifier (URI). Instead, use decodeURI and
decodeURIComponent method.
decodeURI method: Returns the non-encoded form of an encoded Uniform Resource Identifier (URI).
function decodeURI (uristring:string): String
decodeURIComponent method: Returns the non-encoded form of an encoded component of a Uniform Resource Identifier (URI).
function decodeURIComponent (encodeduristring:string): String
How to encode URLs in btw:c# ...
Code: Server.URLEncode (String)
Decoding: Server.urldecode (String) the previous three kinds of client code can be decoded in the background with this method.

Like what:

        var url= "${pagecontext.request.contextpath}/fenye?currentpage=" +pagenumber+ "&queryname=${queryname }&queryaddress=${queryaddress}&querydate=${querydate}&gettag=getmethod ";        URL= encodeuri (URL);        Window.location.href

Test incoming Chinese parameter:

The background decodes the received:

        String queryname = Request.getparameter ("queryname");         // if you are clicking on the page number submission method, Transcode        the Get Commit if null &&! "" . Equals (Gettag.trim ())) {            new String (queryname.getbytes ("iso-8859-1"), "Utf-8");        }
