Javascript 正则表达式替换为不同的值

Question

我想知道是否可以每次用不同的值替换字符串中的每个匹配模式。

假设我在一段文本中找到了 5 个匹配项，我想用一个字符串替换第一个匹配项，用另一个字符串替换第二个匹配项，用另一个字符串替换第三个匹配项，依此类推...是否可以实现？

var synonyms = ["extremely", "exceedingly", "exceptionally", "especially", "tremendously"];

"I'm very upset, very distress, very agitated, very annoyed and very pissed".replace(/very/g, function() {
//replace 5 matches of the keyword every with 5 synonyms in the array
});

Answer 1

您可以尝试在 replace 回调函数中替换匹配项:

var synonyms = ["extremely", "exceedingly", "exceptionally", "especially", "tremendously"];
var cnt = 0;
console.log("I'm very upset, very distress, very agitated, very annoyed and very pissed (and very anxious)".replace(/very/g, function($0) {
  if (cnt === synonyms.length) cnt = 0;
  return synonyms[cnt++]; //replace 5 matches of the keyword every with 5 synonyms in the array
}));

如果匹配项多于数组中的项目，cnt 将确保再次使用第一个项目中的数组项。
