这是它: http://www.exhibitiondesign.com/include/jquery/jquery.banner .1.0.html

我想说我已经快到了,闪烁是主要问题 - 我知道问题是每当链接悬停在开/关时就会触发淡入淡出。我只是不知道如何实现可见性检查或创建相同效果的另一种方法。 我在服务上也有一些有缺陷的逻辑:设计>内容徘徊,“设计”应该保留为两个服务子项。 最后,我想将整个内容封装到一个 .js 中,html 代码也用 document.write 封装。 任何帮助将不胜感激,我不是编码员,我只研究了几周的 js,所以我需要拉门条款。这是相关的css、html和js:

    #banner{width:100%; height:40px; background:#000;}

    #banner ul li a{font-size:9pt; color:#FFF; text-decoration:none;}
    .line1a,.line1b,.line1c,.line1d,.line1e,.line1f{display:none;}

here is it:
http://www.exhibitiondesign.com/include/jquery/jquery.banner.1.0.html

i'd say im nearly there, the flickering is the main issue - and i know the problem is the fades are being triggered whenever links are being hovered on/off. i just dont know how to implement either a visibility check, or another way of creating the same effect.
i also have some flawed logic on the services: design > content hovering, 'design' should remain for both the services children.
at the end of it all, i want to encapsulate the entire thing into a .js, the html code too with document.write.
any help would be appreciated, i'm no coder, and js i've only been looking at for a few weeks so i'd need lamens terms. here is the relevant css, html and js:

    #banner{width:100%; height:40px; background:#000;}
    #banner ul{width:1024px; margin:auto; padding:0; list-style:none;}
    #banner ul li{height:16px; margin:10px 40px 0 0; float:left;}
    #banner ul li a{font-size:9pt; color:#FFF; text-decoration:none;}
    .line1a,.line1b,.line1c,.line1d,.line1e,.line1f{display:none;}
    .line2a,.line2b,.line2c,.line2d,.line2e,.line2f{display:none;}
    .companyname{font-size:16pt; color:#FFF; width:220px; margin:7px 0; float:right;}

让我们一步一步来,首先是交换问题。如果您希望在悬停子级时也保留文本,请将其放在父级

  • 上而不是 上,如下所示:
  • <li class="line1e swap" style="width:60px;">
     <a href="/services/design.html" style="cursor:pointer;">SERVICES</a>
     <div class="line2e">
      <a href="/services/content.html">CONTENT</a>
     </div>
    </li>
    

    然后 jQuery 悬停到匹配,如下所示:

    $(".swap").hover(function(){
      $(this).children("a").text("DESIGN");
    }, function(){
      $(this).children("a").text("SERVICES");
    });
    

    对于所有其他问题,这是因为 mouseovermouseout进入子级时触发,您'我们看到了最常见的副作用,动画闪烁。相反,使用 mouseentermouseleave...或快捷方式,.hover(),如下所示:

    $("#banner").hover(function(){
      $("#banner").stop(true, false).animate({height:'50px'},{queue:false, duration:200, easing: 'easeInQuad'});
      $(this).find("> ul > li").stop(true, true).fadeIn();
    },  function(){
      $("#banner").stop(true, true).animate({height:'40px'},{queue:false, duration:200, easing: 'easeInQuad'});
      $(this).find("> ul > li").stop(true, true).fadeOut();
    });
    
    $("#banner > ul > li").hover(function() {
      $(this).children("div").fadeIn();
    }, function() {
      $(this).children("div").fadeOut();
    });
    

    您可以在此处测试结果。另请注意,通过使用 选择器 相对于 this,您可以避免所有重复的代码并减少处理程序的数量。您还可以删除所有这些 .lineXX 类,除非它们需要用于其他用途。

    Let's take it step by step, first the swap issue. If you want the text to remain when hovering children too, put it on the parent <li> instead of the <a>, like this:

    <li class="line1e swap" style="width:60px;">
     <a href="/services/design.html" style="cursor:pointer;">SERVICES</a>
     <div class="line2e">
      <a href="/services/content.html">CONTENT</a>
     </div>
    </li>
    

    Then jQuery hovers to match, like this:

    $(".swap").hover(function(){
      $(this).children("a").text("DESIGN");
    }, function(){
      $(this).children("a").text("SERVICES");
    });
    

    For all the other issues, it's because mouseover and mouseout fire when entering children, you're seeing the most common side-effect, flickering with animations. Instead, use mouseenter and mouseleave...or the shortcut, .hover(), like this:

    $("#banner").hover(function(){
      $("#banner").stop(true, false).animate({height:'50px'},{queue:false, duration:200, easing: 'easeInQuad'});
      $(this).find("> ul > li").stop(true, true).fadeIn();
    },  function(){
      $("#banner").stop(true, true).animate({height:'40px'},{queue:false, duration:200, easing: 'easeInQuad'});
      $(this).find("> ul > li").stop(true, true).fadeOut();
    });
    
    $("#banner > ul > li").hover(function() {
      $(this).children("div").fadeIn();
    }, function() {
      $(this).children("div").fadeOut();
    });
    

    You can test the result out here. Also note that through the use of selectors relative to this, you can avoid all that duplicate code and slim your handlers way down. You can also remove all those .lineXX classes unless they're needed for something else.
