如何以最简单的方式从字符串中获取值

// 示例字符串
var str = "Name: John, Age: 25, City: New York";

// 使用split()方法获取值
var values = str.split(", ");
var name = values[0].split(": ")[1];
var age = values[1].split(": ")[1];
var city = values[2].split(": ")[1];

console.log("Name:", name); // 输出：John
console.log("Age:", age); // 输出：25
console.log("City:", city); // 输出：New York

// 使用正则表达式获取值
var nameRegex = /Name: (\w+)/;
var ageRegex = /Age: (\d+)/;
var cityRegex = /City: (\w+)/;

var nameMatch = str.match(nameRegex);
var ageMatch = str.match(ageRegex);
var cityMatch = str.match(cityRegex);

console.log("Name:", nameMatch[1]); // 输出：John
console.log("Age:", ageMatch[1]); // 输出：25
console.log("City:", cityMatch[1]); // 输出：New York
