javascript - 从Javascript中的字符串中提取以某个字符开头的单词

Question

我有一个如下所示的字符串

var str = "This product price is £15.00 and old price is £19.00";

我需要获取以“£”开头的单词；结果应为“£15.00”“£19.00”我如何在 Javascript 中执行此操作？

Answer 1

使用 String#match 方法

var str = "This product price is £15.00 and old price is £19.00";

// if `£` follows non-digit also then use
console.log(str.match(/£\S+/g));
// if `£` follows only number with fraction
console.log(str.match(/£(\d+(\.\d+)?)/g));
