使用DOM解析：

var html  = '<p>[my_shortcode post_id="2451"]';
    html += '<div class="my-div-01"><div class="my-div-01">Content div 01</div></div></p>';
    html += '<p>[my_shortcode post_id="1542"]';
    html += '<div class="my-div-02"><div class="my-div-02">Content div 01</div></div></p>';

function shortcode_constrict(html) {
  // Load the HTML string as XML, wrap it in a <root> tag as a XML doc needs one
  var doc = new DOMParser().parseFromString('<root>' + html + '</root>', 'text/xml');
  
  // Remove all div elements
  doc.querySelectorAll('div').forEach(function(div) {
    div.parentNode.removeChild(div);
  });
  
  // Return the modified document's HTML content
  return doc.documentElement.innerHTML;
}

console.log(shortcode_constrict(html));
