what are the differences between json and jsonp?

JSON (Javascript Object Notation) is a convenient way to transport data between applications, especially when the destination is a Javascript application.

Example :

Here is a minimal example that uses JSON as the transport for the server response. The client makes an ajax request with the JQuery shorthand function $.getJSON. The server generates a hash, formats it as JSON and returns this to the client. The client formats this and puts it in a page element.

Server:

get '/json' do
 content_type :json
 content = { :response  => 'Sent via JSON',
            :timestamp => Time.now,
            :random    => rand(10000) }
 content.to_json
end

Client:

var url = host_prefix + '/json';
$.getJSON(url, function(json){
  $("#json-response").html(JSON.stringify(json, null, 2));
});

Output:

  {
   "response": "Sent via JSON",
   "timestamp": "2014-06-18 09:49:01 +0000",
   "random": 6074
  }

JSONP (JSON with Padding)

JSONP is a simple way to overcome browser restrictions when sending JSON responses from different domains from the client. The only change on the Client side with JSONP is to add a callback parameter to the URL.

Server:

get '/jsonp' do
 callback = params['callback']
 content_type :js
 content = { :response  => 'Sent via JSONP',
            :timestamp => Time.now,
            :random    => rand(10000) }
 "#{callback}(#{content.to_json})"
end

Client:

var url = host_prefix + '/jsonp?callback=?';
$.getJSON(url, function(jsonp){
  $("#jsonp-response").html(JSON.stringify(jsonp, null, 2));
});

Output:

 {
  "response": "Sent via JSONP",
  "timestamp": "2014-06-18 09:50:15 +0000",
  "random": 364
}

How to blink text in html for various browsers

How to blink text in html for various browsers

The blink() method is not standard, and may not work as expected in all browsers.
The blink() method is used to display a blinking string.
This method returns the string embedded in the <blink> tag, like this:

<blink>string</blink>

Note:  The blink() method only works in Opera. It is not supported in Internet Explorer, Firefox, Chrome, or Safari.

So alternatively we can try this below:

<span class="blink_text">India's Largest portal is Meetcity.in</span> 
<style type="text/css"> 
.blink_text { 

        -webkit-animation-name: blinker;
 -webkit-animation-duration: 1s;
 -webkit-animation-timing-function: linear;
 -webkit-animation-iteration-count: infinite;

 -moz-animation-name: blinker;
 -moz-animation-duration: 1s;
 -moz-animation-timing-function: linear;
 -moz-animation-iteration-count: infinite;
 animation-name: blinker;
 animation-duration: 1s;
 animation-timing-function: linear; 
    animation-iteration-count: infinite; color: red; 
} 

@-moz-keyframes blinker {
    0% { opacity: 1.0; }

    50% { opacity: 0.0; }

    100% { opacity: 1.0; } 
}

@-webkit-keyframes blinker {  
    0% { opacity: 1.0; }

    50% { opacity: 0.0; }

    100% { opacity: 1.0; } 
} 

@keyframes blinker {  
    0% { opacity: 1.0; } 

    50% { opacity: 0.0; }      

    100% { opacity: 1.0; } 
} 
</style>
