如何隐藏 jQuery 子菜单(ddsmoothmenu)?

发布于 2024-09-04 00:35:01 字数 5644 浏览 6 评论 0原文

我是 jQuery 的新手,我必须承认我还什么都不懂,虽然我认为我有 javascript 的经验,但它的语法对我来说似乎是一种未知的语言。 尽管如此,我还是设法在我的asp.net母版页的标题中实现了此菜单。 甚至在 这里。 但最终,当异步加载新页面时,菜单消失了。我不知道如何隐藏这个该死的 jQuery 菜单。

在 js 文件中注册事件以隐藏/消失的部分之后。我不知道如何获取负责它的部分,甚至我不知道如何在我的 Anchor-onclick 函数中实现该部分,其中我没有对 jQuery 对象的引用。

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.hover(
  function(e){
   $(this).children('a:eq(0)').addClass('selected')
  },
  function(e){
   $(this).children('a:eq(0)').removeClass('selected')
  }
 )
 $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'})
  $subul.data('timers', {})
  this._dimensions={w:this.offsetWidth, h:this.offsetHeight, subulw:$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)
    $parentshadow=$(document.body)
   else{
    var $parentLi=$curobj.parents("li:eq(0)")
    $parentshadow=$parentLi.get(0).$shadow
   }
   this.$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
  }
  $curobj.hover(
   function(e){
    var $targetul=$subul //reference UL to reveal
    var header=$curobj.get(0) //reference header LI as DOM object
    clearTimeout($targetul.data('timers').hidetimer)
    $targetul.data('timers').showtimer=setTimeout(function(){
     header._offsets={left:$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.$shadow.css({opacity:1})
       }
       header.$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)
   },
   function(e){
    var $targetul=$subul
    var header=$curobj.get(0)
    clearTimeout($targetul.data('timers').showtimer)
    $targetul.data('timers').hidetimer=setTimeout(function(){
     $targetul.animate({height:'hide', opacity:'hide'}, ddsmoothmenu.transition.outtime)
     if (smoothmenu.shadow.enable){
      if (ddsmoothmenu.detectwebkit){ //in WebKit browsers, set first child shadow's opacity to 0, as "overflow:hidden" doesn't work in them
       header.$shadow.children('div:eq(0)').css({opacity:0})
      }
      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'})
}

当内容重定向到另一个页面时我想要隐藏的菜单的一个链接(我需要“closeMenu-function”):

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

简而言之:我想淡出子菜单,就像它们自动模糊一样,这样只有标题菜单保持可见,但我不知道如何。

谢谢,蒂姆

编辑:感谢 Starx 为初学者提供的 jQuery 私人课程,我解决了这个问题: 我忘记了 $("#smoothmenu1") 中的#。之后,不难从菜单标题中找到并调用悬停功能,让它们平滑淡出:

$("#smoothmenu1").find("ul").hover(); 

问候, 蒂姆

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 asp.net 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.hover(
  function(e){
   $(this).children('a:eq(0)').addClass('selected')
  },
  function(e){
   $(this).children('a:eq(0)').removeClass('selected')
  }
 )
 $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'})
  $subul.data('timers', {})
  this._dimensions={w:this.offsetWidth, h:this.offsetHeight, subulw:$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)
    $parentshadow=$(document.body)
   else{
    var $parentLi=$curobj.parents("li:eq(0)")
    $parentshadow=$parentLi.get(0).$shadow
   }
   this.$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
  }
  $curobj.hover(
   function(e){
    var $targetul=$subul //reference UL to reveal
    var header=$curobj.get(0) //reference header LI as DOM object
    clearTimeout($targetul.data('timers').hidetimer)
    $targetul.data('timers').showtimer=setTimeout(function(){
     header._offsets={left:$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.$shadow.css({opacity:1})
       }
       header.$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)
   },
   function(e){
    var $targetul=$subul
    var header=$curobj.get(0)
    clearTimeout($targetul.data('timers').showtimer)
    $targetul.data('timers').hidetimer=setTimeout(function(){
     $targetul.animate({height:'hide', opacity:'hide'}, ddsmoothmenu.transition.outtime)
     if (smoothmenu.shadow.enable){
      if (ddsmoothmenu.detectwebkit){ //in WebKit browsers, set first child shadow's opacity to 0, as "overflow:hidden" doesn't work in them
       header.$shadow.children('div:eq(0)').css({opacity:0})
      }
      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:

$("#smoothmenu1").find("ul").hover();

Tim

好吧,我没有读完你的整篇文章。但如果您使用的是 jQuery 菜单,该菜单应该有一个容器元素,如

    并且它们将有一个类或

id如果它是一个 id 则执行

$(document).ready(function() {
      $("#myelementid").hide();
});

如果它有一个类则执行

$(document).ready(function() {
      $(".myelementclass").hide();
});

希望这有助于

更新

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

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

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() {
      $("#myelementid").hide();
});

In case it has a class then do

$(document).ready(function() {
      $(".myelementclass").hide();
});

Hope this helps

UPDATE

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

or

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