Bootstrap Tooltip工作但由于z-index而隐藏？

Question

如果将鼠标悬停在第一支铅笔上，您可以看到工具提示即将出现，但它已被隐藏。

如何告诉所有工具提示显示在其他所有内容之上？

$('.nav-text').on('click', null, function () {
    alert('heyo');
});
$('.nav-text').tooltip({
    'placement': 'right',
        'title': 'heyo'
});

$('.down').click(function() {
  var $move = $('.side-study-box ul');
  $move.css({
    top: '-=20px'
  })

$('.up').click(function() {
  var $move = $('.side-study-box ul');
  $move.css({
    top: '+=20px'
  })
})


$('.nav-text').on('click', null, function() {
  alert('heyo');

$('.nav-text').tooltip({
  'placement': 'right',

Answer 1

只需将工具提示位置设置为fixed，就像这样：

.tooltip {
    position: fixed;
}

请参阅working demo

Answer 2

只需设置data-container。

<a href="#" data-toggle="tooltip" data-container="body" title="first tooltip">
hover over me</a>

Answer 3

不要使用position: fixed ，这更像是一个看起来有效的临时修复程序，但以后会引起问题。

在你的情况下，最好的选择是将工具提示附加到正文（如@machineaddict in a comment所提到的）确保它跟随滚动的铅笔，固定定位不会。

$('.nav-text').tooltip({
    placement: 'right',
        title: 'heyo',
    container: 'body' //<--- use the container option
});

您甚至可以更具体，并使用container: '.side-study-box'确保工具提示遵循其div，即使整个框独立于身体滚动。只需确保容器有position: relative。

正如Diego's answer中所述，您可以使用上面的任何选项作为数据属性：

<a class="nav-text" 
   data-toggle="tooltip" 
   data-container=".side-study-box" 
   data-placement="right" 
   title="heyo">
    ...
</a>

跟随带溢出滚动的div的工具提示

我在原始代码段周围添加了一个.container div，使其变小以强制在溢出时滚动。滚动时，您可以看到工具提示跟随铅笔图标。

$('.nav-text').click(function() {
  console.log('heyo');
}).tooltip({
  placement: 'right',
  title: 'heyo',
  // follows the box even if it is scrolled withinthe container div.
  container: '.container',
});

.container {
  height: 100px;
  overflow: scroll;
  position: relative;
}
.side-study-box {
  background-color: white;
  color: black;
  border: 1px solid #3D6AA2;
  text-align: center;
  height: 160px;
  display: table !important;
  margin: 0px !important;
  margin-left: -1px !important;
}
.side-study-box .viewport {
  height: 120px;
  overflow: hidden;
  position: relative;
}
.side-study-box span {
  position: relative;
  width: 100%;
  font-size: 24px;
  display: table-cell;
  vertical-align: middle;
}
.side-study-box textarea {
  position: relative;
  height: 195px;
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
  width: 100%;
  margin: auto;
  font-size: 18px;

Answer 4

如果您使用的是角度uib-bootstrap，这是最佳解决方案：对$ uibTooltipProvider使用依赖注入，您可以更改默认情况下工具提示和弹出窗口的行为方式;以上属性始终优先：

$uibTooltipProvider.options({
  appendToBody: true
});

Answer 5

如果我们将属性container =“ body”添加到您的html标记中，则它不会随着页面滚动中的html元素一起移动

Answer 6

如果使用npm（SASS）构建引导程序（4.5），则可以在自己的variables.scss文件中调整$zindex-tooltip变量。

在bootstrap 4.5 node_modules/bootstrap/scss/_variables.scss @第690行中

$zindex-tooltip:                    1070 !default;

顺便说一句，您可以在该文件中找到所有变量

Answer 7

位置：固定！重要;在这里工作，但不要忘记！在某些情况下很重要。

Answer 8

只需将属性container="body"添加到您的html标记
