flexiquote旋转器自定义调整

我正在使用flexiquoterotor进行单词按压，我对它进行了调整，以显示下一个和上一个按钮。下面是我的代码

function ($) {
    var callquote;
    quoteRotator = {
    i: 1,
quotes: [";
    $i=0;
    foreach($results as $result){
    echo "'"$openquote<span id='quote'>$result->quote</span>$closequote";
    if($result->author != '')
echo " <span id='quoteauthor'>$result->author</span>";
    echo "'",'n";
        $i++;
        }
],
        numQuotes: ".$i.",
    fadeDuration: ".$fade.",
                    fadeoutDuration: ".$fadeout.",
                    delay: ".$delay.",
                    quotesInit: function(){
                        if (this.numQuotes < 1){
                            document.getElementById('quoterotator').innerHTML='"No Quotes Found'";
                        } else {
                            this.navQuote();
                            this.quoteRotate();
                            this.quotehover();
                        }
                    },
                    navQuote: function() {
                        $('<div id='"quotenav'"></div>').insertAfter('#quotearea');
                        for (n=1; n <= this.numQuotes ; n++) {
        }
$('#quotenav').append('<span onclick='"quoteRotator.callQuote(this,'+n+')'">Next</span>');
for (k= -3; k <= this.numQuotes ; k++) {
        }
                        $('#quotenav').append('<span id='"test'" onclick='"quoteRotator.callQuote(this,'+k+')'">Prev</span>');

                        // insert style
                        $('head').append('<style type='"text/css'">#quotenav {display: block;text-align: center;font-size: 50px;color: #000;}#quotenav span {margin: 0 3px;cursor: pointer;}#quotenav span.active,#quotenav span:hover{color: red;}</style>');
                    },
                    quoteRotate: function(i){
                        if(!i) {
                            i = this.i;
                        }
                        $('#quotenav span').each(function () {
                            $(this).removeClass('active');
                        });
                        $('#quotenav span:nth-child('+i+')').addClass('active');
                        jQuery('#quoterotator').hide().html(this.quotes[i - 1]).fadeIn(this.fadeDuration * 1000).css('filter','');
                        this.i = i % (this.numQuotes) + 1;
                        callquote = setTimeout('quoteRotator.quoteRotate()', (this.delay + this.fadeDuration) * 1000);
                    },
                    callQuote: function(e,n) {
                        clearTimeout(callquote);
                        this.quoteRotate(n);
                    },
                    quotehover: function() {
                        jQuery('#quotearea').mouseenter(function () {
                            clearTimeout(callquote);
                          }).mouseleave(function(){
                                setTimeout('quoteRotator.quoteRotate()', 500);
                          });
                    }
                }
        })(jQuery);

上面的代码没有显示next和prev按钮，而是适用于基于点的导航。
