javascript - 查找字符串中引号之间的值并将该值存储在变量中

Question

我找到了有关我的帖子的链接 How to extract a substring using regex但它是用java编写的。

假设我有一句话:

var sentence = "This is a long sentence but I only want this 'information'";

然后我想提取引号中的值(值:信息)并将其存储在变量中。我该怎么办？

Answer 1

您可以使用String.prototype.slice()、String.prototype.indexOf()、String.prototype.lastIndexOf()

var sentence = "This is a long sentence but I only want this 'information'";

var res = sentence.slice(sentence.indexOf("'") + 1, sentence.lastIndexOf("'"));

console.log(res);
