javascript incorrectly reads commented out code

[ImaginaryDevelopment]

the commented out { in the following code makes fiddlesalad fail to render.

var c = $('#container');
$.each(operations, function (i, e) {
    //foreach( var e in operations){

    var input = document.createElement('input');
    $(input).attr('type', 'button').val(e.key)
        .attr('id', e.id)
        .addClass('operation')
        .attr('title', e.id);

    c.append(input);

    $('input#' + e.id).on('click', function () {
        showcalc(e.f);
    });
});
