How to implement infinite hierarchical horizontal navigation menu with jquery_jquery

The example in this article describes how jquery implements infinite hierarchical horizontal navigation menus. Share it with everyone for your reference. The specific implementation method is as follows:

1. The jquery plug-in version code is as follows:

Copy code The code is as follows:

(function($){
$.fn.extend({
         droplinemenu: function(configs) {
                var configs = $.extend({                                         Over: 200,
out: 100,
                  rightdown:'css/down.gif'
               },configs||{});
This.find(">ul").addClass("dropmenu");
this.find("ul li:has(ul)").addClass('hasmenu').find(">a").append("");
            var currentobj;
                return $('li.hasmenu').hover(function(){                                                                                                                                                                                                                                                                                                                                          if ($.browser.msie) {//Clear the overflow generated under ie:hidden
                               $(this).parent("ul").css({'overflow': 'visible'});
                                                                                                      $(this).find(">ul").stop(true, true).css('top',$(this).height()).slideDown(configs.over);
               },function(){                                                                    $(this).find(">ul").stop(true, true).slideUp(configs.out);
            });
}
});
})(jQuery);

2. Style code

Copy code

The code is as follows:* {margin:0;padding:0} .droplinebar{ Position: absolute;

z-index: 20;

Width: 700px;
}
.droplinebar ul.dropmenu {
position: relative;
}
.droplinebar ul{
width: 100%;
float: left;
font: bold 13px Arial;
background: #242c54 url(bluedefault.gif) center center repeat-x; /*default background of menu bar*/
}
.droplinebar ul li{

4. No plug-in version code:

Copy code The code is as follows:

$(document).ready(function(){
var configs_over = 200,configs_out = 100;
$("#mydroplinemenu").find(">ul").addClass("dropmenu").find("li:has(ul)").addClass('hasmenu').find(">a" ).append("");
$('.dropmenu li.hasmenu').hover(function(){                                       If ($.browser.msie) {//Clear the overflow generated under IE:hidden
                 $(this).parent("ul").css({'overflow': 'visible'});
          }
           $(this).find(">ul").stop(true, true).css('top',$(this).height()).slideDown(configs_over);
},function(){
            $(this).find(">ul").stop(true, true).slideUp(configs_out);
});
});

I hope this article will be helpful to everyone’s jQuery programming.
