替换数据块中的多个模式

您可以传递一个函数来替换：

var hello = "Hello World what a beautiful day";hello.replace(/Hello|World/g, function ($0, $1, $2) // $3, $4... $n for captures{    if ($0 == "Hello")        return "Bye";    else if ($0 == "World")        return "Universe";});// Output: "Bye Universe what a beautiful day";
