How to Avoid Postback on JQuery Button click in PHP

[fanboime]

Here's my script

$( "#button" ).button();
		
		$( "#button" ).click(function( event ) {
		<?PHP
		...
		?>
      });

And here's the input tag

<input id="button" type="submit" value="Add" name = "subBtn" />

Whenever i click the button it triggers postback how can i avoid this?

[gristoi]

$( "#button" ).click(function( event ) {
       event.preventDefault();
});

[fanboime]

$( "#button" ).click(function( event ) {

       event.preventDefault();

});

I've tried this and whenever i click my button nothing is happening...

	$( "#button" ).click(function( event ) {
	<?PHP
	...
	?>

 

PHP is executed on the SERVER before the page gets to the user. It is not possible to execute PHP code directly from JavaScript. You would have to use AJAX to send a request to the server to execute some PHP code.
