javascript - 如何删除段落中的多余行

Question

我有从 api 调用的这条信息:

例如，

"

  1. Assist food and technology department in record keeping and filing"

如何去掉多余的线？

Answer 1

只需删除字符串开头和结尾的所有空格即可。这就是.trim()是:

s = `

  1. Assist food and technology department in record keeping and filing
  
  `;
s = s.trim();
console.log(s);

trim() 的替代方案(如果您的浏览器不支持它？)是正则表达式:

s = '\n\n1. Assist food and technology department in record keeping and filing   \n \r\n   ';
s = s.replace(/^[\s\uFEFF\xA0]+|[\s\uFEFF\xA0]+$/g, '');
console.log(s);
