Encoding Rich Text With JQuery for AJAX

One of the ways software engineers program a smooth application experience is by encoding files and text that are passed between different portions of the software. Rich text format (RTF) is a document file format that encodes characters using an 8-bit format. Using the Javascript-based programming language, jQuery, you can encode characters into RTF that can be used by code built using asynchronous Javascript (AJAX).

Instructions

1. Open up a plain text editor, like Microsoft's Notepad or Mac OS X's TextEdit, both of which are bundled with the operating systems. Create a new document where you can practice coding the jQuery functions that can turn a set of characters into RTF format.

2. Employ the htmlEncode function to initiate the encoding:

   function htmlEncode(value){
   return $('<div/>').text(value).html();
   }

   This code will take everything within the "div" tag and convert it to RTF so it can be used in an AJAX call.

3. Use the opposite function to decode the RTF files, if you need to, by using the following code. This will decode anything in the div tag that's encoded in RTF:

   function htmlDecode(value){
   return $('<div/>').html(value).text();
   }

4. Save the practice code snippets and use them for future reference. Paste the code into the applications to which you need to add encoding and modify them as needed.
