How to hide jQuery Sub-Menus(ddsmoothmenu)?

Question by Tim Schmelter

I’m new to jQuery and i must admit that i’ve understood nothing yet, the syntax appears to me as an unknown language although i thought that i had my experiences with javascript.
Nevertheless i managed it to implement this menu in my masterpage’s header.
Even got it to work that the content-page is loaded with ajax with help from here.
But finally i’m failing with the menu to disappear when the new page was loaded asynchronously. I dont know how to hide this accursed jQuery Menu.

Following the part of the js-file where the events are registered for hiding/disappearing. I dont know how to get the part that is responsible for it and even i dont know how to implement that part in my Anchor-onclick function where i dont have a reference to the jQuery Object.

buildmenu:function($, setting){
 var smoothmenu=ddsmoothmenu
 var $mainmenu=$("#"+setting.mainmenuid+">ul") //reference main menu UL
 $mainmenu.parent().get(0).className=setting.classname || "ddsmoothmenu"
 var $headers=$mainmenu.find("ul").parent()
 $headers.each(function(i){ //loop through each LI header
  var $curobj=$(this).css({zIndex: 100-i}) //reference current LI header
  var $subul=$(this).find('ul:eq(0)').css({display:'block'})
  $'timers', {})
  this._dimensions={w:this.offsetWidth, h:this.offsetHeight, subulw:$subul.outerWidth(), subulh:$subul.outerHeight()}
  this.istopheader=$curobj.parents("ul").length==1? true : false //is top level header?
  $subul.css({top:this.istopheader && setting.orientation!='v'? this._dimensions.h+"px" : 0})
  $curobj.children("a:eq(0)").css(this.istopheader? {paddingRight: smoothmenu.arrowimages.down[2]} : {}).append( //add arrow images
   '<img src="'+ (this.istopheader && setting.orientation!='v'? smoothmenu.arrowimages.down[1] : smoothmenu.arrowimages.right[1])
   +'" class="' + (this.istopheader && setting.orientation!='v'? smoothmenu.arrowimages.down[0] : smoothmenu.arrowimages.right[0])
   + '" style="border:0;" />'
  if (smoothmenu.shadow.enable){
   this._shadowoffset={x:(this.istopheader?$subul.offset().left+smoothmenu.shadow.offsetx : this._dimensions.w), y:(this.istopheader? $subul.offset().top+smoothmenu.shadow.offsety : $curobj.position().top)} //store this shadow's offsets
   if (this.istopheader)
    var $parentLi=$curobj.parents("li:eq(0)")
   this.$shadow=$('<div class="ddshadow'+(this.istopheader? ' toplevelshadow' : '')+'"></div>').prependTo($parentshadow).css({left:this._shadowoffset.x+'px', top:this._shadowoffset.y+'px'})  //insert shadow DIV and set it to parent node for the next shadow div
    var $targetul=$subul //reference UL to reveal
    var header=$curobj.get(0) //reference header LI as DOM object
     header._offsets={left:$curobj.offset().left, top:$curobj.offset().top}
     var menuleft=header.istopheader && setting.orientation!='v'? 0 : header._dimensions.w
     menuleft=(header._offsets.left+menuleft+header._dimensions.subulw>$(window).width())? (header.istopheader && setting.orientation!='v'? -header._dimensions.subulw+header._dimensions.w : -header._dimensions.w) : menuleft //calculate this sub menu's offsets from its parent
     if ($targetul.queue().length<=1){ //if 1 or less queued animations
      $targetul.css({left:menuleft+"px", width:header._dimensions.subulw+'px'}).animate({height:'show',opacity:'show'}, ddsmoothmenu.transition.overtime)
      if (smoothmenu.shadow.enable){
       var shadowleft=header.istopheader? $targetul.offset().left+ddsmoothmenu.shadow.offsetx : menuleft
       var shadowtop=header.istopheader?$targetul.offset().top+smoothmenu.shadow.offsety : header._shadowoffset.y
       if (!header.istopheader && ddsmoothmenu.detectwebkit){ //in WebKit browsers, restore shadow's opacity to full
       header.$shadow.css({overflow:'', width:header._dimensions.subulw+'px', left:shadowleft+'px', top:shadowtop+'px'}).animate({height:header._dimensions.subulh+'px'}, ddsmoothmenu.transition.overtime)
    }, ddsmoothmenu.showhidedelay.showdelay)
    var $targetul=$subul
    var header=$curobj.get(0)
     $targetul.animate({height:'hide', opacity:'hide'}, ddsmoothmenu.transition.outtime)
     if (smoothmenu.shadow.enable){
      if (ddsmoothmenu.detectwebkit){ //in WebKit browsers, set first child shadow's opacity to 0, as "overflow:hidden" doesn't work in them
      header.$shadow.css({overflow:'hidden'}).animate({height:0}, ddsmoothmenu.transition.outtime)
    }, ddsmoothmenu.showhidedelay.hidedelay)
  ) //end hover
 }) //end $headers.each()
 $mainmenu.find("ul").css({display:'none', visibility:'visible'})

one link of my menu what i want to hide when the content is redirected to another page(i need “closeMenu-function”):

<li><a href="DeliveryControl.aspx" onclick="AjaxContent.getContent(this.href);closeMenu();return false;">Delivery Control</a></li>

In short: I want to fade out the submenus the same way they do automatically onblur, so that only the headermenu stays visible but i dont know how.

Thanks, Tim

EDIT: thanks to Starx’ private-lesson in jQuery for beginners i solved it:
I forgot the # in $(“#smoothmenu1”). After that it was not difficult to find and call the hover-function from the menu’s headers to let them fade out smoothly:



Answer by Starx

Ok, I didn’t read your whole post. But if you are using a jQuery Menu, that menu should having a container element like <div> or <ul> and they will either have a class or id

In case it is a id then do

$(document).ready(function() {

In case it has a class then do

$(document).ready(function() {

Hope this helps


$("#mainmenu").children().hide(); // to hide all child elements


$(".submenu").hide(); //to hide every submenu
