如何计算 HTML 字符串中的字数？

Question

I have a HTML string from a rich editor. I want to implement a feature in javascript that will count the number of words which are visible to user. The condition is the count should exclude the html tags and things which are not visible to the user in rich editor

Answer 1

  countWords = (richHtml) => {
    var regex = /(<([^>]+)>)/ig;
    var body = richHTML.split("><").join("> <");;
    var result = body.replace(regex, "");
    var arr = result.split(" ")
    var newArr = []
    arr.forEach((el, i) => {
      if (el != "" && el != "&nbsp;" && el != "&nbsp;&nbsp;" && el != "'") {
        newArr.push(el)
      }
    })
    return newArr.length
  }
