ES6:使用案例说明术语过滤数据

Question

这是我data按标题值过滤的方法:

data.filter(x => x.title.includes(term))

所以数据就像

Sample one
Sample Two
Bla two

将被"减少"为

Bla two

如果我过滤了two.

但我需要得到过滤结果

Sample Two
Bla two

Answer 1

您可以使用不区分大小写的正则表达式:

// Note that this assumes that you are certain that `term` contains
// no characters that are treated as special characters by a RegExp.
data.filter(x => new RegExp(term, 'i').test(x.title));

一种更简单,更安全的方法是将字符串转换为小写并进行比较:

data.filter(x => x.title.toLowerCase().includes(term.toLowerCase()))
