javascript - Bootstrap 工具提示无法使用 JS

Question

我试图让 Bootstrap 工具提示在我的应用程序中工作，但似乎没有任何效果..这让我有点发疯......我可以看到工具提示，但它看起来不应该..动画不起作用样式不起作用..我不知道如何解决..

我正在基于 javascript 构建 1-100% 的比例尺.. 当用户将鼠标悬停在其中一个比例尺上时，它会显示百分比 - 查看照片

这是我的代码:HTML:

{% load bootstrap %}
{% load static %}
{% load i18n %}
{% load survey_extras %}

<table class="table">
    <!--<thead>
      <tr>
        <th> Question  </th>
        <th> Answers </th>
      </tr>
    </thead> -->
<tbody>
  {% for form in response_form %}
         {% if form.field.widget.attrs.category == category.name or not form.field.widget.attrs.category %}
          <tr class="{% if form.errors%} danger {% endif %}">
              <td>
                <div class="container-fluid">
                  <div class="question-title row">

                    </div>
                    <div class="col-7">
                      <h5>{{ form.label|safe }}</h5>
                    </div>
                  </div></div>

                  {% if form.field.required %}
                    <span class="glyphicon glyphicon-asterisk" style="color:red"> </span>
                  {% endif %}
                <span class="help-inline" style="color:red">
                    <strong> {% for error in  form.errors %}{{ error }}{% endfor %} </strong>

它应该是这样的:

已编辑 img:

CSS:

.scale{
    display: inline-flex;
    border: black 1px solid;
    width:71%;
    margin:auto;
    display: -webkit-box;
    display: -moz-box;
    display: -ms-flexbox;
    display: -webkit-flex;
    display: flex;
    align-items: center;
    justify-content: center;
}
.numbers{
    width: 5px;
    height: 40px;
    background-color: #66bb9e;
    margin-right: 2px;
}

.numbers:hover {
    background-color: #fa7770;
}

.scale-title{
  display: inline-flex;
  width:71%;
  margin:auto;
  display: -webkit-box;
  display: -moz-box;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;
  align-items: center;
}


.scaleleft{
font-size: 0.7rem;
text-align: left;
}

.scaleright{
  font-size: 0.7rem;
  text-align: right;
}

.answers p{
  margin-bottom: 3rem;
}

.scale-title .container .row .col{
padding-right:0;
padding-left: 0;
}

.tooltip-inner {
    background-color:#fa7770;
    margin-bottom: 3px;
    font-weight: 400;
    font-family: Ubuntu;
}

Answer 1

您的 JavaScript 在 DOM 外部创建相关的工具提示组件，这意味着您现在的初始化($(function() { } 或 $(document).ready())不会影响这些元素。

对于通过 AJAX 或以其他方式在 DOM 之外插入的任何内容来说，这是一个非常常见的问题，并且需要对选择器的初始化方式进行微小的改动。

关于 Bootstrap，工具提示组件的一个选项可能是:

$('body').tooltip({
    selector: '[data-toggle="tooltip"]',
    container: 'body'
});

在上面的代码中，您将组件初始化为一个存在的元素 ( <body> ) 并声明将实际触发工具提示出现的选择器。这将影响您的 <body> 中的任何 元素不管它是否是初始 HTML DOM 的一部分。

注意:在上面的示例中，我指定了 container您可能认为有必要，也可能没有必要。您可以在此处阅读有关该特定选项(和其他选项)的更多信息:
