如何从字符串转换数字，并返回相同的格式?

//INPUT as STRING
var dollar1 = "US $59.99 - 69.99 / piece"
var dollar2 = "US $237.50 - 277.50 /lot"
var US_to_MUR_rate = 35;
//FUNCTION
function convert ( string, rate) {
//what should be here ?
return str_converted;
}
//EXPECTED OUPUT as STRING:
var ruppes1 = convert (dollar1, US_to_MUR_rate);
var ruppes2 = convert (dollar2, US_to_MUR_rate);
console.log(rupees1);
"MUR Rs2099.65 - 2449.65 / piece"
console.log(rupees2);
"MUR Rs8032.5 - 9712.5 /lot"


//INPUT as STRING
var dollar1 = "US $59.99 - 69.99 / piece"
var dollar2 = "US $237.50 - 277.50 / lot"
var dollar3 = "US $54 - 60 / lot"
var US_to_MUR_rate = 35;
//FUNCTION
function convert ( string, rate) {
  return string
    .replace(/'d+(?:'.'d+)?/g, function(match) {
      return (parseFloat(match) * US_to_MUR_rate).toFixed(2);
    })
    .replace(/US '$/, 'MUR Rs');
}
//EXPECTED OUPUT as STRING:
var rupees1 = convert (dollar1, US_to_MUR_rate);
var rupees2 = convert (dollar2, US_to_MUR_rate);
var rupees3 = convert (dollar3, US_to_MUR_rate);
console.log(rupees1);
console.log(rupees2);
console.log(rupees3);

当然，这个答案的某些部分是显式编码的，除非您希望它不同

var dollar1 = "US $59.99 - 69.99 / piece"
var dollar2 = "US $237.50 - 277.50 /lot"
var US_to_MUR_rate = 35;
function convert(string, rate){
	var converted_price = string.match(/('d+)'.('d*)/g).map(function(number){
		return (number*rate).toFixed(2)
	})
	var unit = string.match(/('/'s*'w+)/g)
	return "MUR Rs"+converted_price.join(' - ')+" "+unit
}
var rupees1 = convert(dollar1, US_to_MUR_rate);
var rupees2 = convert(dollar2, US_to_MUR_rate);
console.log(rupees1);
console.log(rupees2);
