如何从分号分隔的字符串中打印第一句话？ [复制]

Question

我在数据库表中有一列，其中保存类型字符串。它保存由分号分隔的多行，就像这样 -

this is first sentence;this is second sentence;this is third sentence

我只想打印第一行，即 -

this is first sentence

知道如何使用 JavaScript 实现吗？

Answer 1

使用String.prototype.split

const string ='this is first sentence;this is second sentence;this is third sentence'
const sentences = string.split(';')
const first = sentences[0]
console.log(first)
