const格式=(…args) = > args.shift () .replace (/ % ([jsd]) / g, x = > x = = =“% j”?JSON.stringify(args.shift()): const name = 'Csaba' const格式化= format('Hi %s，今天是%s，您的数据是%j'，名称，日期()，{数据:{国家:'匈牙利'，城市:'布达佩斯'}}) console.log(格式化)

如果使用node.js, console.log()将format string作为第一个参数:

 console.log('count: %d', count);

跑龙套。格式可以做到这一点。

它将是v0.5.3的一部分，可以像这样使用:

var uri = util.format('http%s://%s%s', 
      (useSSL?'s':''), apiBase, path||'/');

下面是Node.js中的一个多行字符串文本示例。

> let name = 'Fred'
> tm = `Dear ${name},
... This is to inform you, ${name}, that you are
... IN VIOLATION of Penal Code 64.302-4.
... Surrender yourself IMMEDIATELY!
... THIS MEANS YOU, ${name}!!!
...
... `
'Dear Fred,\nThis is to inform you, Fred, that you are\nIN VIOLATION of Penal Code 64.302-4.\nSurrender yourself IMMEDIATELY!\nTHIS MEANS YOU, Fred!!!\n\n'
console.log(tm)
Dear Fred,
This is to inform you, Fred, that you are
IN VIOLATION of Penal Code 64.302-4.
Surrender yourself IMMEDIATELY!
THIS MEANS YOU, Fred!!!

试试JS中的sprintf 或者你可以用这个要点

这样做:

s = 'hello ' + my_name + ', how are you doing'

更新

使用ES6，你也可以这样做:

s = `hello ${my_name}, how are you doing`
