这是一个旧的。但它出现了。如果你在编辑器中留下任何空格，它会把它们放在那里。

if
  const text = `a very long string that just continues\
  and continues and continues`;

只要用普通的+符号

if
  const text = `a very long string that just continues` +
  `and continues and continues`;

@ codingconspiracy提出的解决方案在节点7上不适合我。好吧，如果我在第一行不使用续行，它就会工作，否则它就会失败。

这可能不是最好的解决方案，但它没有任何问题:

(`
    border:1px solid blue;
    border-radius:10px;
    padding: 14px 25px;
    text-decoration:none;
    display: inline-block;
    text-align: center;`).replace(/\n/g,'').trim();

这是一个旧的。但它出现了。如果你在编辑器中留下任何空格，它会把它们放在那里。

if
  const text = `a very long string that just continues\
  and continues and continues`;

只要用普通的+符号

if
  const text = `a very long string that just continues` +
  `and continues and continues`;

另一种选择是使用Array。像这样加入:

[
    'This is a very long string. ',
    'It just keeps going ',
    'and going ',
    'and going ',
    'and going ',
    'and going ',
    'and going ',
    'and going',
].join('')

如果你在字面值的换行符处引入了一个续行符(\)，它不会在输出时创建换行符:

const text = `a very long string that just continues\
and continues and continues`;
console.log(text); // a very long string that just continuesand continues and continues

你可以直接吃掉模板文字中的换行符。
