为什么 Bootstrap 4 弹出窗口中缺少 HTML 属性？

Question

$(document).ready(function () {
        $("[data-toggle=popover]").popover({
            html: true,
            content: function () {
                return "<div style='color:red;'>test</div>";
            }
        });

<a class="btn btn-primary" data-html="true" data-toggle="popover" data-placement="bottom">Click Me</a>

当我在 Bootstrap 4 弹出窗口中使用 HTML 内容时，缺少 HTML 属性。我希望看到红色文本，但它输出没有红色样式的 div 标签。

    $("[data-toggle=popover]").popover({
        html: true,
        content: function () {
            return "<div style='color: red;'>Test</div>";
        }
    });

Answer 1

Bootstrap 弹出窗口执行一些清理以去除“不安全”属性 - 默认情况下它是打开的。

与我之前的评论和我的测试相反，即使在旧版本中它也是默认的。知道手册总是好的:-)

https://getbootstrap.com/docs/4.4/components/popovers/#options

允许的属性是按标签定义的：

https://getbootstrap.com/docs/3.4/javascript/#js-sanitizer

可以将sanitize选项设置为 false将其关闭。

$("[data-toggle=popover]").popover({
  html: true,
  sanitize: false,
  content: function () {
    return "<div style='color: red;'>Test</div>";
  }
});

Answer 2

您可以添加一个类并将 css 设置为：

$(document).ready(function() {
  $('[data-toggle="popover"]').popover({
    html: true,
    content: function() {
      return "<div class='color-red'>Test</div>";
    }
  });
});

.color-red{ color: red; }

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" />

<a href="#" data-toggle="popover" title="Popover">Test</a>
