initialise external php file - javascript / jQuery

I have a div with id trigger in my page. I have a php file action.php which will delete contents in my text file mytext.txt. I want to do that when i click trigger using jquery. Or is there any function to do that without php file??

Thanks in advance... :)

You can bind a click handler to your DIV. It's actually better if you had a link instead, but not essential (i.e. - html5)

$('#trigger').click(function(){
   $.get('action.php', {}, function(data){ //populate {} if you want to send any data
      alert(data);//whatever your action.php file echoes out.
   });
});

Using $.ajax, you can call your PHP script from Javascript.. You can't access neither client-side nor server-side files (such as mytext.txt) from javascript.
