jquery dropline 在鼠标悬停时保持第二个

Question

有没有办法在this dropline menu 上获得此行为？当鼠标从菜单项悬停时，需要第二级或第三级保持活动状态一秒钟。

为了澄清，您正在寻找对鼠标移动的某种延迟反应？如果是这样，请查看这个 jQuery hoverintent 插件：http://cherne.net/brian/resources/jquery.hoverIntent.html

编辑：我认为您需要编辑您的菜单脚本以将任何 .hover 实例替换为 .hoverIntent。我在 jsfiddle 中测试时遇到了麻烦，但看看它是否有效：

var droplinemenu={

arrowimage: {classname: 'downarrowclass', src:'http://www.odzaci.rs/wp-content/themes/typo/images/down.gif', leftpadding: 5}, //customize down arrow image
animateduration: {over: 200, out: 300}, //duration of slide in/ out animation, in milliseconds

buildmenu:function(menuid){
    jQuery(document).ready(function($){
        var $mainmenu=$("#"+menuid+">ul")
        var $headers=$mainmenu.find("ul").parent()
        $headers.each(function(i){
            var $curobj=$(this)
            var $subul=$(this).find('ul:eq(0)')
            this._dimensions={h:$curobj.find('a:eq(0)').outerHeight()}
            this.istopheader=$curobj.parents("ul").length==1? true : false
            if (!this.istopheader)
                $subul.css({left:0, top:this._dimensions.h})
            var $innerheader=$curobj.children('a').eq(0)
            $innerheader=($innerheader.children().eq(0).is('span'))? $innerheader.children().eq(0) : $innerheader //if header contains inner SPAN, use that
            $innerheader.append(
                '<img src="'+ droplinemenu.arrowimage.src
                +'" class="' + droplinemenu.arrowimage.classname
                + '" style="border:0; padding-left: '+droplinemenu.arrowimage.leftpadding+'px" />'
            )

            // THIS IS THE PART I REPLACED

            var config = {    
     over: function(e){
            var $targetul=$(this).children("ul:eq(0)")
            if ($targetul.queue().length<=1) //if 1 or less queued animations
                if (this.istopheader)
                    $targetul.css({left: $mainmenu.offset().left, top: $mainmenu.offset().top+this._dimensions.h})
                if (document.all && !window.XMLHttpRequest) //detect IE6 or less, fix issue with overflow
                    $mainmenu.find('ul').css({overflow: (this.istopheader)? 'hidden' : 'visible'})
                $targetul.slideDown(droplinemenu.animateduration.over)
        },
timeout: 1000, // number = milliseconds delay before onMouseOut    
out: function(e){
            var $targetul=$(this).children("ul:eq(0)")
            $targetul.slideUp(droplinemenu.animateduration.out)
        }
};

$curobj.hoverIntent( config );




        }) //end $headers.each()
        $mainmenu.find("ul").css({display:'none', visibility:'visible', width:$mainmenu.width()})
    }) //end document.ready
}
}
