"Go" URL encoding (encodeuricomponent and decodeURIComponent)

Transfer from Http://blog.jhonse.com/archives/2032.jhonse

Recently in the use of the CI framework, found a problem, the URL of the Get link, if the Chinese characters, there will be problems, hint: Link characters do not pass, so in the Internet to find a lot of methods, Modify the CI framework's config.php file, as well as the url.php file, have been modified, and finally did not solve the problem.

At the beginning of the use, are in the Google Browser debugging, what problems are not, Chinese characters can pass, at that time also really a little admire Google. However, in IE, 360 browser has been tested, immediately appear above the problem. Think for one hours, the solution is to submit the data, by JS to the Chinese code, and then in the CI framework to receive the encoded data, decoding can be.

Encoding function:

encodeURIComponent ()

The encodeURIComponent () function encodes a string as a URI component.

Grammar

encodeURIComponent (uristring)

Parameters	Description
Uristring	Necessary. A string that contains the URI component or other text to encode.

return value

A copy of the uristring, where some of the characters will be replaced by a hexadecimal escape sequence.

Description

The method does not encode ASCII letters and numbers, nor does it encode these ASCII punctuation marks: –_. ! ~ * ' ().

Other characters (such as:;/?:@&=+$,# These punctuation marks used to separate the URI component) are replaced by one or more hexadecimal escape sequences.

Hints and Notes

Tip: Note the difference between the encodeURIComponent () function and the encodeURI () function, which assumes that its arguments are part of a URI (such as a protocol, hostname, path, or query string). Therefore, the encodeURIComponent () function escapes punctuation marks that are used to separate the various portions of the URI.

Instance

In this example, we will encode the URI using encodeURIComponent ():

<script type= "Text/javascript" >document.write (encodeURIComponent ("http://www.w3school.com.cn")) document.write ("<br/>") document.write (encodeURIComponent ("http://www.w3school.com.cn/p 1/")) document.write ("<br/>") document.write (encodeURIComponent ("/?:@&=+$#")) </script>

Output:

Http%3a%2f%2fwww.w3school.com.cnhttp%3a%2f%2fwww.w3school.com.cn%2fp%201%2f%2c%2f%3f%3a%40%26%3d%2b%24%23

decoding function:

decodeURIComponent ()

Definition and usage

The decodeURIComponent () function decodes the URI encoded by the encodeURIComponent () function.

Grammar

decodeURIComponent (uristring)

Parameters	Description
Uristring	Necessary. A string that contains the encoding URI component or other text to decode.

return value

A copy of the uristring, where the hexadecimal escape sequence is replaced by the character they represent.

Instance

In this example, we will use decodeURIComponent () to decode the encoded URI:

<script type= "Text/javascript" >var test1= "Http://www.w3school.com.cn/My first/" document.write ( encodeURIComponent(test1) + "<br /> ") document.write ( decodeURIComponent(test1) ) </script>

Output:

Http%3a%2f%2fwww.w3school.com.cn%2fmy%20first%2fhttp://www.w3school.com.cn/my first/
