Javascript 将ajax功能限制为单个菜单

我正在尝试为一个客户端在几页上调整子菜单。我目前正在我设置的本地主机站点上进行测试

这些是我正在工作的实际站点的页面。上的食品菜单和上的员工部分

我找到了这段代码，我试图通过将contentSelector更改为guts并将$menu部分更改为“.menuLeft、.menuRight”来更改我想要ajaxify的食物菜单：

// History.js It!
// v1.0.1 - 30 September, 2012
// https://gist.github.com/854622
(function(window,undefined){

    // Prepare our Variables
    var
        History = window.History,
        $ = window.jQuery,
        document = window.document;

    // Check to see if History.js is enabled for our Browser
    if ( !History.enabled ) {
        return false;
    }

    // Wait for Document
    $(function(){
        // Prepare Variables
        var
            /* Application Specific Variables */
            contentSelector = '#guts',
            $content = $(contentSelector).filter(':first'),
            contentNode = $content.get(0),
            $menu = $('.menuRight,.menuLeft').filter(':first'),
            activeClass = 'active selected current youarehere',
            activeSelector = '.active,.selected,.current,.youarehere',
            menuChildrenSelector = '> li,> ul > li',
            completedEventName = 'statechangecomplete',
            /* Application Generic Variables */
            $window = $(window),
            $body = $(document.body),
            rootUrl = History.getRootUrl(),
            scrollOptions = {
                duration: 800,
                easing:'swing'
            };

        // Ensure Content
        if ( $content.length === 0 ) {
            $content = $body;
        }

        // Internal Helper
        $.expr[':'].internal = function(obj, index, meta, stack){
            // Prepare
            var
                $this = $(obj),
                url = $this.attr('href')||'',
                isInternalLink;

            // Check link
            isInternalLink = url.substring(0,rootUrl.length) === rootUrl || url.indexOf(':') === -1;

            // Ignore or Keep
            return isInternalLink;
        };

        // HTML Helper
        var documentHtml = function(html){
            // Prepare
            var result = String(html)
                .replace(/<\!DOCTYPE[^>]*>/i, '')
                .replace(/<(html|head|body|title|meta|script)([\s\>])/gi,'<div class="document-$1"$2')
                .replace(/<\/(html|head|body|title|meta|script)\>/gi,'</div>')
            ;

            // Return
            return result;
        };

        // Ajaxify Helper
        $.fn.ajaxify = function(){
            // Prepare
            var $this = $(this);

            // Ajaxify
            $this.find('a:internal:not(.no-ajaxy)').click(function(event){
                // Prepare
                var
                    $this = $(this),
                    url = $this.attr('href'),
                    title = $this.attr('title')||null;

                // Continue as normal for cmd clicks etc
                if ( event.which == 2 || event.metaKey ) { return true; }

                // Ajaxify this link
                History.pushState(null,title,url);
                event.preventDefault();
                return false;
            });

            // Chain
            return $this;
        };

        // Ajaxify our Internal Links
        $.menuS.ajaxify();

        // Hook into State Changes

            var
                State = History.getState(),
                url = State.url,
                relativeUrl = url.replace(rootUrl,'');

            // Set Loading
            $.menuS.addClass('loading');

            // Start Fade Out
            // Animating to opacity to 0 still keeps the element's height intact
            // Which prevents that annoying pop bang issue when loading in new content
            $content.animate({opacity:0},800);

            // Ajax Request the Traditional Page
            $.ajax({
                url: url,
                success: function(data, textStatus, jqXHR){
                    // Prepare
                    var
                        $data = $(documentHtml(data)),
                        $dataBody = $data.find('.document-body:first'),
                        $dataContent = $dataBody.find(contentSelector).filter(':first'),
                        $menuChildren, contentHtml, $scripts;

                        // ^ we use the full url here as that is what reinvigorate supports
                    }

                }
            }); // end ajax

        }); // end onStateChange

    }); // end onDomLoad

})(window); // end closure

当我测试它时，它在食物菜单上非常有效。然而，它也影响了主菜单，我的代码最终出现在页面上

我需要做哪些更改，以便只有子菜单才能调用javascript

---

非常感谢您的帮助。

解决了，别问我怎么办。对于其他寻找答案的人，以下是我所做的

我改变了这一点：

// Ajaxify our Internal Links
$body.ajaxify();

为此：

// Ajaxify our Internal Links
$('.menuLeft,.menuRight').ajaxify();

我一直试图在这里添加菜单类，没有括号和单引号。一旦我把这些东西放进去，一切都安排妥当了。现在，只有那些菜单是ajaxified的。

我看不出它对主菜单有什么影响。当我从其中一个菜单页面单击主菜单上的某个页面时，该页面会加载到食品菜单应该所在的区域。当我从主页开始选择一个页面时，我会在页眉和页脚中分别得到一个代码块，而不会重新加载页面。这可能是导致其他菜单项ajaxify的原因吗？“//Ajaxify我们的内部链接$body.Ajaxify；'
