jQuery has no postJSON function so you will have to find another way. But there is a solution!

You can use the regular post function:  jQuery.post( url, [data], [callback] , [type]) specifing the last parameter [type] to be “json”.

Here is the complete example:

var callback = function (returndata, status) {
//here you can do whatever you want with the returndata object
};

jQuery.post( url, {mydata: mydata, mydata1: mydata1}, callback, "json") ;

3. How to build a clickmap using PHP and jQuery

For start we need jQuery, ui.core and ui.sortable, make sure you download them and include them in the header of your application:

<script src=”jquery-latest.js”></script>
<script src=”ui.core.js”></script>
<script src=”ui.sortable.js”></script>

after that we use this little code snippet to make the magic:

<script>

$(document).ready(function(){

$(“.thelist”).sortable({

cursor: ‘.handle’,

update : function () {

serial=$(‘.thelist’).sortable(‘serialize’,'id’);

$(“#target”).load(“load.php”, { list: serial } );

}

});

});

</script>

In the html we have a div with the class thelist, this is the div that contains the sortable elements, each having a unique id.

<div class=”thelist”>

<div class=”divo” id=”el_1″>Item 1</div>

<div class=”divo” id=”el_2″>Item 2</div>

<div class=”divo” id=”el_3″>Item 3</div>

<div class=”divo” id=”el_4″>Item 4</div>

<div class=”divo” id=”el_5″>Item 5</div>

</div>

After each drag and drop operation in load.php will receive a string with the order of the divs, the result will be something like this:

el[]=3&el[]=4&el[]=5&el[]=2&el[]=1

This data is sent to load.php with POST, beeing contained in the list variable: $_POST['list']

This is only a basic demonstration, you can do much advanced functionality with jQuery Sortable, you just need a little time and a little coffee.

3. How to use post for JSON instead of jQuery’s getJSON

• Record the X and Y coordinates of the mouse cursor when it is clicked on a web page.
• Save those coordinates to a database
• When called, display a “clickmap” on top of the web page visually displaying the locations of those clicks.

The results are amazing, check it out here. This thing could be used to track clicks in any webpage and use this stuff in marketing or usability studies.
