Parsing json with jQuery

Parsing json data with jQuery is not complicated at all. Here is an efficient example on how to parse json data and append it to your web page. http://www.catswhocode.com/blog/useful-jquery-code-snippets

parse-json.js
content_copyfile_download
function parseJson(){
  //Start by calling the json object, I will be using a 
        //file from my own site for the tutorial 
	//Then we declare a callback function to process the data
	$.getJSON('hcj.json',getPosts);
 
	//The process function, I am going to get the title, 
        //url and excerpt for 5 latest posts
	function getPosts(data){
 
		//Start a for loop with a limit of 5 
		for(var i = 0; i < 5; i++){
			//Build a template string of 
                        //the post title, url and excerpt
			var strPost = '<h2>' 
				      + data.posts[i].title
				      + '</h2>'
				      + '<p>'
				      + data.posts[i].excerpt
				      + '</p>'
				      + '<a href="'
				      + data.posts[i].url
				      + '" title="Read '
				      + data.posts[i].title
				      + '">Read ></a>';
 
			//Append the body with the string
			$('body').append(strPost);
 
		}
	}
 
}
 
//Fire off the function in your document ready
$(document).ready(function(){
	parseJson();				   
});
