encoder.js

An encoding library in JavaScript

HTML encode and decode

HTML encode an input string

var encoder = require('encoder.js');
var input = '100 > 200 is incorrect';
var encoded = encoder.encodeHTML(input); //100 > 200 is incorrect

HTML decode an input string

var encoder = require('encoder.js');
var intput = '100 > 200 is incorrect';
var decoded = encoder.decodeHTML(input); //100 > 200 is incorrect

HTML attribute encode and decode

HTML attribute encode an input string, this method only encode 4 characters: &, <, ' and "

var encoder = require('encoder.js');
var input = '100<200';
var encoded = encoder.encodeHTMLAttr(input); //100&lt;200

// but '>' will be not encoded
input = '200>100';
encoded = encoder.encodeHTMLAttr(input); //200>100

To decode HTML attribute, use encoder.decodeHTML

JavaScript encode and decode

Characters '\r\t"\n\b\f' will be escaped to '\\r\\t\\"\\n\\b\\f'

var input = '\r\t"\n\b\f';
var encoded = encoder.encodeJavaScript(input); //\r\t\"\n\b\f

Any control character (code < 0x20) will be encoded

var input = String.fromCharCode(0) + String.fromCharCode(16) + String.fromCharCode(31);
var encoded = encoder.encodeJavaScript(input); //\u0000\u0010\u001f

Characters #133, #8232 and #8233 will be encoded

var input = String.fromCharCode(133) + String.fromCharCode(8232) + String.fromCharCode(8233);
var encoded = encoder.encodeJavaScript(input); //\u0085\u2028\u2029

XML encode and decode

XML encode has the same behavior as HTML encode except XML encode converts ' into '

var input = '\'';
var encoded = encoder.xmlEncode(input); //'

URI encode and decode

URI encode an input string

var encoder = require('./encoder.js');
var input = 'http://www.example.com/abc 123';
var encoded = encoder.encodeURI(input); //http://www.example.com/abc%20123

URI decode an input string

var encoder = require('./encoder.js');
var input = 'http://www.example.com/abc%20123';
var decoded = encoder.decodeURI(input); //http://www.example.com/abc 123

Base64 encode and decode

Base64 encode a string

var input = 'Hello World!';
var encoded = encoder.base64Encode(input); //"SGVsbG8gV29ybGQh"

Decode a base64 string

var input = 'SGVsbG8gV29ybGQh';
var encoded = encoder.base64Decode(input); //"Hello World!"
