Answer 1

try this

var duplicated = {};

$('[id]').each(function () {   

    var ids = $('[id="' + this.id + '"]');

    if ( ids.length <= 1 ) return  ;

    if ( !duplicated[ this.id ] ){
         duplicated[ this.id ] = [];   
    }       

    duplicated[ this.id ].push( this );

});

// remove duplicate last ID, for elems > 1 
for ( var i in duplicated){

    if ( duplicated.hasOwnProperty(i) ){  

             $( duplicated[i].pop() ).remove();            
    }
}

Answer 2

$('[id]').each(function() {
   var $ids = $('[id=' + this.id + ']');
   if ($ids.length > 1) {
     if(this.id === your_id)//which is duplicating
         $ids.not(':first').remove();
     }
});

Answer 3

Use jquery filter :gt(0) to exclude first element.

$('[id]').each(function () {
    $('[id="' + this.id + '"]:gt(0)').remove();
});

Or select all the available elements, then exclude the first element using .slice(1).

$('[id]').each(function (i) {
    $('[id="' + this.id + '"]').slice(1).remove();
});

Answer 4

you can try

$("#ID").nextAll().remove();

Answer 5

Try:

 $('[id="' + this.id + '"]:not(#" + this.id + ":first)').remove();

Answer 6

I'd use not() to remove the current element from ids and remove the rest:

(Fiddle)

$('body').on("click", ".placeholder", function() {

    data = '<section id="e1"><input name="e1name" /></section><section id="two"><input name="two" value="two section" /></section>';

    $('form').append(data);

        // ideally I'd like to run this function after append but after googling I find that's not possible.
        // for each ID ...
        $('[id]').each(function () {

            var ids = $('[id="' + this.id + '"]');

            if (ids.length>1) {                    
                ids.not(this).remove();            
            }

            return;

        });

});
