正则表达式删除?等

Question

在上一个问题(需要链接)中，我尝试删除Twitter上的匆忙标记和评论。我的字符串是这样的文本：

@lien_ayy92 ??% Real ?Avail▶#Jakarta #Bekasi ?Excl/Incl ?Expo▶6-7 Juli #Cirebon ?Wajib DP? ?Cek BIO? https://local.com/

我想试着删除不重要的图标和文本。

我的代码来自前面的代码

​

let clean = function (data) {
	data = data.replace(/(?:https?|ftp):\/\/[\n\S]+|\B[@#]\w+\b|\b\w+[@#]\B|\B[^\w\s]{2,}\B|\b[a-zA-Z]{1,3}\b|[0-9]+|[$&+,:;=?@#|'<>.^*()%!-/]|\ud83d[\ude00-\ude4f]/g, '');
	return data;
}
let stopwords = function (docs) {
  	docs = clean(docs);
	docs = docs.trim();	
    docs = docs.toLowerCase();	
	docs = docs.split(' ');
  let wordsstop = ['about'];
	let docs1 = new Array;
  var x =  0;
  for(let i = 0; i < docs.length; i++){
       if(wordsstop.indexOf(docs[i]) !== -1 || docs[i] == ""){

      }else{
      docs1[x] = docs[i]
      x++;
      }
  }
  return docs1;
}

console.log(stopwords('?@lien_ayy92 ??% Real ?Avail▶#Jakarta #Bekasi ?Excl/Incl ?Expo▶6-7 Juli #Cirebon ?Wajib DP? ?Cek BIO? https://local.com about data'));

​

我想要这样的结果：

["real","juli","data"];

您可以使用Array.prototype.filter删除所有带有特殊字符的项。

​

let clean = function (data) {
	data = data.replace(/(?:https?|ftp):\/\/[\n\S]+|\B[@#]\w+\b|\b\w+[@#]\B|\B[^\w\s]{2,}\B|\b[a-zA-Z]{1,3}\b|[0-9]+|[$&+,:;=?@#|'<>.^*()%!-/]|\ud83d[\ude00-\ude4f]/g, '');
	return data;
}
let stopwords = function (docs) {
  	docs = clean(docs);
	docs = docs.trim();	
    docs = docs.toLowerCase();	
	docs = docs.split(' ');
  let wordsstop = ['about'];
	let docs1 = new Array;
  var x =  0;
  for(let i = 0; i < docs.length; i++){
       if(wordsstop.indexOf(docs[i]) !== -1 || docs[i] == ""){

      }else{
      docs1[x] = docs[i]
      x++;
      }
  }
  
  // filter code below
  var resultDocs = docs1.filter(function(data) {
    var tmp = data.replace(/[a-zA-Z$&+,:;=?@#|'<>.^*()%!-/]/g, '');
    if (tmp.length === 0) {
      return true;
    }
  });

  return resultDocs;

}

console.log(stopwords('?@lien_ayy92 ??% Real ?Avail▶#Jakarta #Bekasi ?Excl/Incl ?Expo▶6-7 Juli #Cirebon ?Wajib DP? ?Cek BIO? https://local.com about data'));
