How to Find Out Last Index of each() in jQuery?

Question

I have something like this...

$( 'ul li' ).each( function( index ) {    $( this ).append( ',' );  } ); 

I need to know what index will be for last element, so I can do like this...

if ( index !== lastIndex ) {    $( this ).append( ',' );  } else {    $( this ).append( ';' );  } 

Any ideas, guys?

Answer 1

var total = $('ul li').length; $('ul li').each(function(index) {     if (index === total - 1) {         // this is the last one     } }); 

Answer 2

var arr = $('.someClass'); arr.each(function(index, item) { var is_last_item = (index == (arr.length - 1)); });
