我如何选择除特定元素以外的所有内容? [英] How can I select everything except specific element?

问题描述

这是我的代码:

$.fn.right = function() {
   return $(document).width() - (this.offset().left + this.outerWidth());
}

$(document).ready(function(){
  $('a').bind('mouseenter', function() {
    var self = $(this);
    this.iid = setTimeout(function() {
      var tag_name = self.text(),
          top      = self.position().top + self.outerHeight(true),
          right = self.right();
      $('body').append("<div class='tag_info'>Some explanations about "+tag_name+"</div>");
      
      $(".tag_info").css({top: top + "px", right: right + "px"}).fadeIn(200);  
      
    }, 525);
  }).bind('mouseleave', function(){
    if(this.iid){
      clearTimeout(this.iid)
      $('.tag_info').remove();
    }
  });
});

    body{
      padding: 20px;
      direction: rtl;
    }

    a {
        color: #3e6d8e !important;
        background-color: #E1ECF4;
        padding: 2px 5px;
    }
    .tag_info{
      position: absolute;
      width: 130px;
      height: 100px;
      display:none;
      background-color: black;
      color: white;
      padding: 10px;
    }

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
    <a>long-length-tag</a>
    <a>tag</a>

它也可以正常工作，当鼠标离开标签时，弹出窗口将被删除.现在，当鼠标离开标签并继续显示该弹出窗口时，我想保留该弹出窗口.否则应将其删除.我该怎么办?

It works as well and that pop-up will be removed when your mouse leaves the tag. Now I want to keep that pop-up when the mouse leaves the tag and goes on that pop-up. Otherwise it should be removed. How can I do that?

推荐答案

您可以添加条件来检查鼠标是否悬停在弹出窗口上，然后再将其删除:

You can add a condition to check if the mouse is hovering over the pop-up before removing it:

if ($('.tag_info:hover').length == 0) {....}

您需要在弹出式窗口本身上添加一个事件，以在mouseleave

And you need to add an event on the pop-up itself to remove it on mouseleave

查看代码段:

$.fn.right = function() {
  return $(document).width() - (this.offset().left + this.outerWidth());
}

$(document).ready(function() {
  $('a').bind('mouseenter', function() {
    var self = $(this);
    this.iid = setTimeout(function() {
      var tag_name = self.text(),
        top = self.position().top + self.outerHeight(true),
        right = self.right();
        
      var pop_up = $('<div />', {
        "class": 'tag_info',
        text: "Some explanations about " + tag_name,
        mouseleave: function(e){
             $(this).remove();
        }})  
      
      $('body').append(pop_up);

      $(".tag_info").css({
        top: top + "px",
        right: right + "px"
      }).fadeIn(200);

    }, 525);
  }).bind('mouseleave', function() {
    if (this.iid) {
      clearTimeout(this.iid)
      if ($('.tag_info:hover').length == 0) {
        $('.tag_info').remove();
      }
    }
  });


});

body {
  padding: 20px;
  direction: rtl;
}

a {
  color: #3e6d8e !important;
  background-color: #E1ECF4;
  padding: 2px 5px;
}

.tag_info {
  position: absolute;
  width: 130px;
  height: 100px;
  display: none;
  background-color: black;
  color: white;
  padding: 10px;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a>long-length-tag</a>
<a>tag</a>
