jQuery 中的淡出

发布于 2024-10-05 09:23:02 字数 3068 浏览 7 评论 0原文

我正在尝试添加一个 Jquery 函数来更新跨度内链接悬停时的 div 我的html结构是

  <ul><li>
      <div class="timeline">


         <span>by</span>
         <span class="vcard">
           <a class="underline user-link" href="/users/aruna">Aruna </a>
         </span>
         <div style="display: none;" class="image_hover">
               Student
               <p>
                 <a onclick="" href="#">Show additional details</a>
                 <a href="#">view</a>
                 <p>Employee ID : </p>
                 <p>Project Name: </p>
                 <p>Project Role : r</p>
                 <p>Supervisor Name : </p> 
              </p>
         </div>

         <span class="timeline">about 1 day ago</span>
    </div>
    </li>
    <li>
      <div class="timeline">


         <span>by</span>
         <span class="vcard">
           <a class="underline user-link" href="/users/jasmine">jasmine </a>
         </span>
         <div style="display: none;" class="image_hover">
               Professor
               <p>
                 <a onclick="" href="#">Show additional details</a>
                 <a href="#">view</a>
                 <p>Employee ID : </p>
                 <p>Project Name: </p>
                 <p>Project Role : r</p>
                 <p>Supervisor Name : </p> 
              </p>
         </div>
         <span class="timeline">about 1 day ago</span>
    </div>
    </li>
 </ul>

我写的jQuery是

我写的

   jQuery(document).ready(function(){
      var _selectedLinkEl = null;
      var _detailEl = null;
      var body = jQuery("body");
      var elem=null;
jQuery(".user-link").mouseover(function(event) {
    _selectedLinkEl = this;
    _detailEl=jQuery(event.target).parent().next();
   //_detailEl.show();
  _detailEl.fadeIn("slow");
  elem=jQuery(this).parent().next();
 _href=jQuery(this).attr('href').split("/")[2];

jQuery.post('/users/user_detail/?name='+_href,
     function(data){
    //elem.html(data).show();
            elem.html(data).fadeIn("slow");
     });//post

 body.mouseover(_bodyMouseOverFunction);
  }); // user-link

var _bodyMouseOverFunction = function(event) {
        if(event.target != _selectedLinkEl &&      
           event.target != _detailEl &&
           jQuery.inArray(_detailEl, jQuery(event.target).parent() ) == -1) {

      //_detailEl.hide();
    _detailEl.fadeOut("slow");
     body.unbind("mouseover", _bodyMouseOverFunction);
   }
 };// mouseover

});

上面的jquery更新图像悬停div并通过fadeIn显示div，但它始终淡出。

仅当我的鼠标悬停在 div(image_hover) 或任何 body 元素之外时，我才尝试淡出 DIV image_hover 。

在这种情况下，如果我的鼠标位于链接上、div 上或内部的任何元素上div (image_hover) ， Div 不应淡出。

请对此/提出建议。

怎么办呢？

         </div>
         <span class="timeline">about 1 day ago</span>
    </div>
    </li>
 </ul>

The jQuery i have written is

I wrote like

   jQuery(document).ready(function(){
      var _selectedLinkEl = null;
      var _detailEl = null;
      var body = jQuery("body");
      var elem=null;
jQuery(".user-link").mouseover(function(event) {
    _selectedLinkEl = this;
    _detailEl=jQuery(event.target).parent().next();
   //_detailEl.show();
  _detailEl.fadeIn("slow");
  elem=jQuery(this).parent().next();
 _href=jQuery(this).attr('href').split("/")[2];

jQuery.post('/users/user_detail/?name='+_href,
     function(data){
    //elem.html(data).show();
            elem.html(data).fadeIn("slow");
     });//post

 body.mouseover(_bodyMouseOverFunction);
  }); // user-link

var _bodyMouseOverFunction = function(event) {
        if(event.target != _selectedLinkEl &&      
           event.target != _detailEl &&
           jQuery.inArray(_detailEl, jQuery(event.target).parent() ) == -1) {

      //_detailEl.hide();
    _detailEl.fadeOut("slow");
     body.unbind("mouseover", _bodyMouseOverFunction);
   }
 };// mouseover

});

The above jquery updates the image-hover div and its displaying the div by fadeIn but its getting fadeout at all times .

I am trying to fade out the DIV image_hover only if my mouse hover is out of the div(image_hover) or any body elements..

In the cases , if my mouse is on the link or on the div or on any of the elements inside the div (image_hover) , the Div should not fadeout..

Please give suggestions for this/.

How to do so ??

您的 HTML 是问题的一部分。为了将其从需要保持打开的区域中拉出来，必须位于触发器标记内，但我还注意到其他事情：

  • 默认情况下，包含“image_hover”的 DIV 是隐藏的（因此无论如何都不起作用）。
  • HTML 中没有图像标签可用作图像悬停（看起来很奇怪）。
  • 您在 2 个截然不同的对象（顶部 DIV 和“大约 1 天前”SPAN）中使用“时间轴”CSS 类......只有 1 个似乎是时间轴。
  • 您有 2 个链接（例如锚点）暗示可能用作切换：“显示其他详细信息”和“查看”（是哪个？）
  • 您的每个链接切换都位于要切换的内容内。
  • 您有一个 SPAN 只是包含单词（不需要）
  • 考虑将您的“时间轴”标签移出切换区域。

因此，我更改了您的 HTML 并创建了下面的潜在解决方案。这将执行打开“详细信息”区域的所需行为（并将在悬停时保持打开状态）。

此外，您实际上并不需要隐藏“详细信息”区域……但无论如何我还是把它留给了您。

同时，请考虑以下潜在的解决方案：

Your HTML is part of the issue. To pull this off the area that needs to remain open has to live within your triggers tag, but I noticed other things as well:

  • The DIV containing the "image_hover" is hidden by default (so won't work anyhow).
  • There is no image tag in your HTML to be used as an image-hover (just seemed odd).
  • You're using the "timeline" CSS class on 2 distinctly different objects (the top DIV and in the "about 1 day ago" SPAN)...only 1 seems to be a timeline.
  • You have 2 links (e.g. anchors) that imply possible usage as toggles: "Show additional details" and "view" (which is it?)
  • Each of your link-toggles live inside that which is to be toggled.
  • You have a SPAN simply to contain the word by (not needed)
  • Consider moving your "timeline" tag OUT of the toggle-area.

As such, I altered your HTML and created the potential solution below. This will execute the desired behavior of opening the "details" area (and will remain open while hovering).

Additionally, you don't really need to hide the "details" area...but I left that in for you anyway.

In The Meantime, Consider The Following Potential Solution:

             text-decoration: none;
        }
