删除字符串中的现有标签。我该如何预防？

Question

例如，如果文本中具有字体大小或其他标签，它将完全删除它。

代码前；

<p id="TextHere">[...] <span style='color:red'>people</span> and 10<sup>12</sup>, [...]</p>

代码后；

<p id="TextHere">[...] <span>people</span>, <span>and</span> <span>1012</span>[...]</p>

如果有样式或类的标签被删除。

如果单词中有标签；如何保护该标签？

在示例代码的全文中； <sup>和<span style>标签可用，但是这些标签在Javascript代码工作后不会显示。

完整代码：

    /**
 * Sentence element
 * @var {Object}
 */
var $sentence = $('#TextHere');
/**
 * Selected words output element
 * @var {Object}
 */
var $selected = $('#selectedWords');

var previosSelectedWords = 'aute,dolor';
var PSW = previosSelectedWords.split(',');
/**
 * Wrap each word in a sentence in a span
 * @param {String} sentence
 * @return {String}
 */
function wrapSentence(sentence) {
  // Get element contents and split by whitespacegit
  var words = $sentence.text().split(/\s+/);
  // Create an empty array for storing wrapped elements
  var wrapped = [];



  // Loop through each word and wrap
for (var j = 0; j < PSW.length; j++) {
    for (var i = 0; i < words.length; i++) {
        if (PSW[j] == words[i]) {
            var prevS = '<span class="previosSelecteds">' + words[i] + '</span>';
            words[i] = prevS;
        } 
    }
}

for (var i = 0; i < words.length; i++) {
    if (!words[i].includes('previosSelecteds')) {
        wrapped.push('<span>' + words[i] + '</span>');
    }
    else {
        wrapped.push(words[i]);
    }
}


  // Combine words into a string
  return wrapped.join(' ');
}

/**
 * Find all selected words in $sentence element
 * @return {Array}
 */
function getSelected() {
  // Create an empty array for storing selected words
  var selected = [];
  // Find all spans with the highlight class
  $sentence.find('span.highlight').each(function() {
    // Push span values to array
    selected.push($(this).text());
  });
  // Return results
  return selected;
}
$sentence.html(wrapSentence());
$sentence.on('click', 'span', function() {
  // Add/remove the highlight class
  $(this).toggleClass('highlight');
  // Update the selected output
  $selected.text(getSelected().join(', '));
  document.getElementById("ImWo").value = getSelected();
});
