EncodeURIComponent

From PlainOldWebserver

This is the right encoding scheme to use for form-submitted information, since it does not preserve the characters, "&+=".

  var enc_uri = encodeURI(";,/?:@&=+$  ABC &+=");
  document.writeln(" Encoded is "+enc_uri);
  var dec_uri = decodeURI(enc_uri);
  document.writeln(" Decoded is "+dec_uri);
  var enc_uri = encodeURIComponent(";,/?:@&=+$  ABC &+=");
  document.writeln(" Component encoded is "+enc_uri);
  var dec_uri = decodeURIComponent(enc_uri);
  document.writeln(" Component decoded is "+dec_uri);

Result:

  Encoded is ;,/?:@&=+$%20%20ABC%20&+=
  Decoded is ;,/?:@&=+$  ABC &+=
  Component encoded is %3B%2C%2F%3F%3A%40%26%3D%2B%24%20%20ABC%20%26%2B%3D
  Component decoded is ;,/?:@&=+$  ABC &+=
