Getting id of class

Question

$(".eventer button[name=myBtn]").click(function() { 
console.log('clicked'); 
thisBtn = $(this); 
parent = $(this).parent(); 
num = parent.data('num'); 
id = parent.data('id'); 

if(typeof num != 'number'){ 
num = 0; 
} 
$(this).attr('disabled', true); 

$.post('javas.php', {num: (num-1), id: id}, function(data) { console.log('Ajax     success'); 

parent.next('.status').html(data); 
thisBtn.attr('disabled', false); // reset  });





console.log('Ajax success'); 
parent.data('num', --num); 
parent.next('.status').html(data); 
thisBtn.attr('disabled', false); // reset 
} );
} ); 


console.log('-- end'); 

}); 

How would i get the id of the class that has been clicked on, this is what i have so far, i want to send the id of the post along with the value of num (already being sent). How would i do this, thanks any help is appreciated!

Answer 1

Although class attribute in tag is called 'class' , in javascript 'class' is a reserved keyword therefore you should use:

 $(this).attr('className')  

Answer 2

To get the id, simply do var id = this.id;

EDIT: $(this).attr('id') also works, but why do it the hard way? this.id is pure Javascript

Answer 3

Use attr function:

id = $(this).attr('id');

Answer 4

You can just get the ID from the attributes:

var theId = $(this).attr( "id" );
