有没有一种方法可以在javascript中执行String.Format()?

哎哟,真糟糕。

偷自 another post :

String.format = function() {
  var s = arguments[0];
  for (var i = 0; i < arguments.length - 1; i++) {       
    var reg = new RegExp("\\{" + i + "\\}", "gm");             
    s = s.replace(reg, arguments[i + 1]);
  }

  return s;
}

例如 JavaScript equivalent to printf/string.format

我正在寻找一个类似的东西,并决定原型的“模板”对象。

从原型 examples

// the template (our formatting expression)
var myTemplate = new Template(
 'The TV show #{title} was created by #{author}.');

// our data to be formatted by the template
var show = {
  title: 'The Simpsons',
  author: 'Matt Groening',
  network: 'FOX'
};

// let's format our data
myTemplate.evaluate(show);
// -> "The TV show The Simpsons was created by Matt Groening."
