当鼠标悬停时 jquery dropline 保持第二个

Question

有没有办法在此下拉菜单上获得此行为？需要第二级或第三级才能保持活动状态当鼠标从菜单项悬停时一秒钟。

澄清一下，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悬停意图插件： http://cherne.net/brian/resources /jquery.hoverIntent.html

编辑： 我认为您需要编辑菜单脚本以将 .hover 的任何实例替换为 .hoverIntent。我在 jsfiddle 中测试这个时遇到问题，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
}
}
