ReactJS中如何去除字符串中的引号？含split后处理场景

你已经用str.split('.')拆分了段落，现在要去掉拆分后字符串里的引号（包括示例里的中文引号“”），可以用正则表达式结合replace()方法实现，给你两种方案：

方案一：先处理引号再拆分（更高效） #

先把整个字符串里的引号全部去掉，再执行拆分操作：

const str = `My mamma stood up and lifted a box off the ground. “We’re in America,
Rune. They speak English here. You’ve been speaking English for as long as
you’ve been speaking Norwegian. It’s time to use it.”`;

// 全局替换所有中文引号（“”）和英文双引号（""）
const processedStr = str.replace(/[“”"]/g, '');
// 拆分处理后的字符串
const splitResult = processedStr.split('.');

方案二：拆分后逐个处理元素 #

如果已经完成了拆分操作，遍历数组里的每个元素，单独去除引号：

const str = `My mamma stood up and lifted a box off the ground. “We’re in America,
Rune. They speak English here. You’ve been speaking English for as long as
you’ve been speaking Norwegian. It’s time to use it.”`;

// 先拆分字符串
const splitArr = str.split('.');
// 遍历数组，逐个去除引号
const cleanedArr = splitArr.map(item => item.replace(/[“”"]/g, ''));

说明 #

正则表达式/[“”"]/g中的[“”"]是字符集，包含了中文左引号、中文右引号和英文双引号，g标记表示全局替换（即替换所有匹配到的引号）。如果只需要处理中文引号，把正则改成/[“”]/g即可。

处理后你会得到期望的结果：

My mamma stood up and lifted a box off the ground. We’re in America,
Rune. They speak English here. You’ve been speaking English for as long as
you’ve been speaking Norwegian. It’s time to use it.
