当我在这个函数中使用scrollTo jQuery插件时,我得到一个`无法读取属性’切片’的undefined`消息

我在JS控制台中收到此错误：

16827Uncaught TypeError: CAnnot read property 'slice' of undefined

当我放置$(“.menu”).scrollTo($(“li.matched”).attr(“id”),800);在里面.

function popupPlace(Dict) {
    $popup = $('div#dish-popup');
    $popup.render(Dict,window.dishPopupTemplatE);
    if(typeof(Dict.dish) === 'undefined') {
        $popup.addClass('place-only');
    } else {
        $popup.removeClass('place-only');
    }

    var $place = $('div#dish-popup div.place');
    var place_id = Dict.place._id;
    if(liked[place_id]) {
        $place.addClass('liked');
    } else {
        $place.removeClass('liked');
    }
    if(Dict.place.likes) {
        $place.addClass('has-likes');
    } else {
        $place.addClass('zero-likes');
    }


    var tokens = window.currentSearchTermTokens;
    var tokenRegex = tokens && new RegExp($.map(tokens,RegExp.escapE).join('|'),'gi');
    $.each(Dict.place.products,function(n,product) {
        $product = $('#menu-item-'+product.id);
        if(liked[place_id+'/'+product.id]) {
            $product.addClass('liked');
        }
        if(tokens && matchesDish(product,tokens)) {
            $product.addClass('matched');
            $product.highlight(tokenRegeX);
        } else {
            $product.removeClass('matched');
            $product.removeHighlight();
        }
        if(product.likes) {
            $product.addClass('has-likes');
        } else {
            $product.addClass('zero-likes');
        }
    });

    $('#overlay').show();
    $('#dish-popup-container').show();

    // Scroll to matched dish
    //$("a#scrolll").attr("href","#" + $("li.matched").attr("id"));
    //$("a#scrolll").attr("href","#" + $("li.matched").attr("id"));
    //$("a#scrolll").trigger("click");
    $(".menu").scrollTo( $("li.matched").attr("id"),800 );

    // Hide dish results on mobile devices to prevent having a blank space at the bottom of the site
    if (Modernizr.mq('only screen and (max-width: 640pX)')) {
        $('ol.results').hide();
    }

    $(".close-dish-popup").click(function() {
        $("#overlay").hide();
        $("#dish-popup-container").hide();
        $('ol.results').show();
        changeState({},['dish','place','serp']);
    });

    showPopupMap(Dict.place,"dish-popup-map");
}

有什么建议来解决这个问题吗？
