JavaScript コードで「Uncaught Syntax Error: Unexpected Identifier」というエラーが表示されます。このコードは、基本的にチュートリアルからの 1 対 1 のコピーであり、html ファイルに適合するように調整されています。エラーは、「Create StickyNote」関数内の 86 行目で発生します。コードは次のとおりです。

(function ($, $S) {
//$ jQuery
//$S window.localStorage
//Variables Declaration
var $board = $('#board'),
    //Board where the stickyNotes are stuck
    stickyNoteClass, //Singleton Object containing the Functions to work with the LocalStorage
    len = 0,
    //Length of Objects in the LocalStorage 
    currentNotes = '',
    //Storage the html construction of the stickyNotes
    o; //Actual stickyNoteClass data in the localStorage



//Manage the stickyNotes in the Local Storage
//Each stickyNote is saved in the localStorage as an Object

        var $this = $(this);
        //data-key is the attribute to know what item delete in the localStorage
        stickyNote.remove($this.attr('data-key'));
        $this.closest('.stickyNote').fadeOut('slow', function () {
            $(this).remove();
        });

@FelixKling が指摘したように、複数行の文字列は許可されていません。これを変える：

$('#new stickyNote').click(function () {
    $board.append('<div class="stickyNote" style="left:20px;top:70px">
            <span class="delete" title="Close">x</span>
            <h1>Drag Me</h1>
            <p class="editable">Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum..</p>
</div>');

    /*Dont need to do this, as the draggable is implemented in the html file for all
    divs which are placed within the #board.
    ------------------------------------------------------------------------------------
    ------------------------------------------------------------------------------------
    $(".stickyNote").draggable({
        cancel: '.editable'
    });*/
});

これに：

    $board.append('<div class="stickyNote" style="left:20px;top:70px">' +
            '<span class="delete" title="Close">x</span>' +
            '<h1>Drag Me</h1>' +
            '<p class="editable">Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum..</p>' +
            '</div>');
