javascript - ES6 : Filter data with case insensitive term

Question

这就是我按标题值过滤一些数据的方式:

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

这样的数据

Sample one
Sample Two
Bla two

将被“减少”为

Bla two

如果我按两个过滤。

但是我需要得到过滤后的结果

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));

也许更简单和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()))
