javascript - 如何用 javascript 或 jQuery 中的数组值替换字符串中的出现次数？

Question

我有以下字符串和数组:

var message = 'This is a @[20] very fun, @[75] evening.';
var array_values = {"20": "really", "112": "extreme", "75": "happy"};

如何将出现的 @[number] 替换为相应的数组值，以获得以下结果:

message = 'This is a really very fun, happy evening.';

谢谢!

一种方法:

var parsed = message.replace(/@\[(\d+)\]/g, function(m, v) {
    return array_values[v] || m;
});
