JS encode decode

All the online search is escape, and the need for coding is not the same thing, hard to find the results saved for later use

JS to encode the text involves 3 functions: Escape,encodeuri,encodeuricomponent, the corresponding 3 decoding function: unescape,decodeuri,decodeuricomponent

1, passing parameters need to use encodeuricomponent, so that the combined URL will not be # and other special characters truncated.

For example: <script language= "JavaScript" >document.write (' <a href= ' http://passport.baidu.com/?logout&aid=7 &u= ' +encodeuricomponent ("http://cang.baidu.com/bruce42") + ' "> Exit </a> ');</script>

2, the URL to jump when you can use the whole encodeURI

For example: location.href= "/encodeuri" ("http://cang.baidu.com/do/s?word= Baidu &ct=21");

3, JS Use the data can use escape

For example: Search the history record of the Tibetan.

4, Escape to the Unicode value other than 0-255 to encode the output%u**** format, in other cases escape,encodeuri,encodeuricomponent encoding results are the same.

The most used should be encodeuricomponent, which is to convert the Chinese, Korean and other special characters into the utf-8 format of the URL encoding, So if you need to use encodeURIComponent to pass parameters to the background, you need the background decoding to Utf-8 support (the encoding in form is the same as the current page encoding method)

Escape does not encode characters with 69: *,+,-,.,/,@,_,0-9,a-z,a-z

encodeURI does not encode 82 characters:!,#,$,&, ', (,), *,+,,,-,.,/,:,;,=,?,@,_,~,0-9,a-z,a-z

encodeURIComponent does not encode 71 characters:!, ', (,), *,-,.,_,~,0-9,a-z,a-z

According to the instructions, I need a encodeuricomponent function.

According to the above-mentioned
1, browser, the URL of the form is consistent with the page encoding
2, the browser with XMLHTTP sent URL is consistent with the browser default settings
3, the request URL is consistent with the server, no garbled appearance
