正则表达式过滤html标签只留下文本

str.replace(/(.*)<div>/, "$1").replace(/(.*)<p>/, "$1");

function setContent(str) {
  str = str.replace(/<\/?[^>]*>/g, ""); //去除HTML tag
  str.value = str.replace(/[ | ]*\n/g, "\n"); //去除行尾空白
  str = str.replace(/\n[\s| | ]*\r/g, "\n"); //去除多余空行
  return str;
}

function removeHTMLTag(str) {
  str = str.replace(/<\/?[^>]*>/g, ""); //去除HTML tag
  str = str.replace(/[ | ]*\n/g, "\n"); //去除行尾空白
  str = str.replace(/\n[\s| | ]*\r/g, "\n"); //去除多余空行
  str = str.replace(/&nbsp;/gi, ""); //去掉&nbsp;
  return str;
}

//去除html标签
function deleteHtmlTag(str) {
  str = str.replace(/<[^>]+>|&[^>]+;/g, "").trim(); //去掉所有的html标签和&nbsp;之类的特殊符合
  return str;
}

description.replace(/<(?!img).*?>/g, "");

//如果保留img,p标签，则为：
description.replace(/<(?!img|p|/p).*?>/g, "");
