HTML

You only need to define the following structure in the HTML page:

Currently online:

JQuery

First, we want to define an animation process that uses the animate () function of jQuery to transform from one number to another. The following magic_number () custom function integrates the code as follows:

Function magic_number (value) {var num = $("# number"); num.animate ({count: value}, {duration: 500, step: function () {num.text (String (parseInt (this.count);}});}

Then the update () function uses jQuery's $.getJSON () to send an ajax request to the background number.php, and after getting the corresponding PHP, call magic_number () to show the latest numbers. To see better results, we use setInterval () to set the interval between code execution.

Function update () {$.getJSON ("number.php?jsonp=?", function (data) {magic_number (data.n);});}; setInterval (update, 5000); / / execute update () once every 5 seconds

PHP

In the actual project, we will use PHP to get the latest data in the database and return it to the front end through PHP. For a better demonstration, this example uses random numbers and returns the js,number.php code to the front end in json format as follows:

$total_data = array ('n'= > rand (0999)); echo $_ GET ['jsonp']. Json_encode ($total_data). ')'
