如何使用 css 在悬停工具提示上显示使用省略号缩短的相同文本？

Question

我有一个例子，其中一些字符串太长，我希望将它们缩短。但是，我希望当我将鼠标悬停在字符串上时能够看到整个字符串。

.don_single_donatori {
  width: 250px;
  min-height: 310px;
}

.overview span {
  text-overflow: ellipsis;
  width: 100px;
  white-space: nowrap;
  overflow: hidden;
  display: inline-block;
}

.overview em {
  font-style: normal;
  color: #000;
  float: right;
}

<div class="don_single_donatori">
  <div class="viewport">
    <div class="overview">
      <p><span>This is my full name which should be shortend</span><em>2.000,00 EUR</em></p>
      <p><span>Anonymous</span><em>2.000,00 EUR</em></p>
      <p><span>Anonymous</span><em>500,00 EUR</em></p>
      <p><span>This is another long name that needs shortening</span><em>2.000,00 EUR</em></p>
      <p>Anonymous<em>2.000,00 EUR</em></p>
    </div>

我在网上找到的大多数方法都使用两个字符串，即您用鼠标悬停在其上的文本与您用于工具提示的文本是分开的（如此处的帖子中所示）。但就我而言，我有相同的文本。为同一文本设置两个条目似乎是多余的。

不能只使用span的title属性吗？？？

<style>
.don_single_donatori {
  width: 250px;
  min-height: 310px;
}

.overview span {
  text-overflow: ellipsis;
  width: 100px;
  white-space: nowrap;
  overflow: hidden;
  display: inline-block;
}

.overview em {
  font-style: normal;
  color: #000;
  float: right;
}
</style>
<div class="don_single_donatori">
    <div class="viewport">
        <div class="overview">
            <p><span title="This is my full name which should be shortend">
            This is my full name which should be shortend
            </span><em>2.000,00 EUR</em></p>
            <p><span>Anonymous</span><em>2.000,00 EUR</em></p>
            <p><span>Anonymous</span><em>500,00 EUR</em></p>
            <p><span title="This is another long name that needs shortening">
            This is another long name that needs shortening
            </span><em>2.000,00 EUR</em></p>
            <p>Anonymous<em>2.000,00 EUR</em></p>
        </div>
    </div>
</div>

如果您不想要重复的文本，请使用 CSS 选择器，这样如果跨度有标题，则使用该标题作为内容。然后只需删除带有标题的 span 中的内容，如下所示：

<style>
.don_single_donatori {
    width: 250px;
    min-height: 310px;
}

.overview span {
    text-overflow: ellipsis;
    width: 100px;
    white-space: nowrap;
    overflow: hidden;
    display: inline-block;
}

.overview em {
    font-style: normal;
    color: #000;
    float: right;
}
span[title]::before {
    content: attr(title);
}
</style>
<!-- ... -->
<div class="don_single_donatori">
    <div class="viewport">
        <div class="overview">
            <p><span title="This is my full name which should be shortend">
            </span><em>2.000,00 EUR</em></p>
            <p><span>Anonymous</span><em>2.000,00 EUR</em></p>
            <p><span>Anonymous</span><em>500,00 EUR</em></p>
            <p><span title="This is another long name that needs shortening">
            </span><em>2.000,00 EUR</em></p>
            <p>Anonymous<em>2.000,00 EUR</em></p>
        </div>
    </div>
</div>
