Bootstrap 4.3.1 Popover不在Popover内容内显示表格 [英] Bootstrap 4.3.1 Popover Does Not Display Table Inside Popover Content

问题描述

我有一个Bootstrap 4.3.1 Popover，其内容嵌入了表格.显示所有内容，但不显示该表.在下面的代码中，我尝试了content和直接$('#a02').html()的功能.

I have a Bootstrap 4.3.1 Popover with a Table embedded inside the content. Everything is displayed but the table is not. In the below code, I've tried both the function for content as well as directly $('#a02').html().

$("[data-toggle=popover]").popover({
    html: true,    
    content: function() { return $('#a02').html(); },  // Also tried directly without function
    title: 'Test'
  }).click(function() {
	  $(this).popover('show');
  });

<a href="#" data-toggle="popover" data-trigger="focus" data-placement="right">
   Click Here for Popover
</a>

<div id="a02" style="display: none;">
   Some text before table
   <div>
      <table width="100%">
          <thead>
              <th>Column 1</th>
              <th>Column 2</th>
              <th>Column 3</th>
          </thead>
          <tbody>
              <tr>
                  <td>1</td>
                  <td>2</td>
                  <td>3</td>
              </tr>
          </tbody>
      </table>
   </div>
</div>

有些人试图向我展示可以与Bootstrap 3一起使用的JSFiddle.我采用了他们的JSFiddle，只是将Bootstrap引用更改为4，但它坏了. Bootstrap 3 JSFiddle | Bootstrap 4 JSFiddle

Some people have tried showing me a JSFiddle that works with Bootstrap 3. I took their JSFiddle and merely changed the Bootstrap refs to 4, and it broke. Bootstrap 3 JSFiddle | Bootstrap 4 JSFiddle

推荐答案

工具提示和Popover使用内置的清理工具来清理接受HTML的选项

Tooltips and Popovers use a built-in sanitizer to sanitize options which accept HTML

https://getbootstrap.com/docs/4.3/getting-started /javascript/#sanitizer

尝试一下:

$(function() {
    $.fn.popover.Constructor.Default.whiteList.table = [];
    $.fn.popover.Constructor.Default.whiteList.tr = [];
    $.fn.popover.Constructor.Default.whiteList.td = [];
    $.fn.popover.Constructor.Default.whiteList.th = [];
    $.fn.popover.Constructor.Default.whiteList.div = [];
    $.fn.popover.Constructor.Default.whiteList.tbody = [];
    $.fn.popover.Constructor.Default.whiteList.thead = [];

  $("[data-toggle=popover]").popover({
    html: true,
    content: function() {
      var content = $(this).attr("data-popover-content");
      return $(content).children(".popover-body").html();
    },
    title: function() {
      var title = $(this).attr("data-popover-content");
      return $(title).children(".popover-heading").html();
    }
  });
});
