如何使用 Lodash 将字符串与正则表达式匹配？

Question

I'm unable to successfully match a string to a regex using Lodash.

I've would attempt the following code example:

regex = /foo/;

// ele.id might be undefined
_.result(ele.id, 'match(regex)');
_.invoke(ele.id, ['match'], [regex]);
_.invoke(ele.id, ['match'], ['regex']);

Does anyone know how to string match a regex argument using Lodash?

Answer 1

Why don't you use vanilla JS for this?

 var regex = /foo/; var string = "foo"; console.log(regex.test(string))

Answer 2

_.invoke is the correct function to use, but your syntax is slightly wrong. Take a look at the docs : The arguments to invoke the method with (3rd parameter of invoke ) are not in an array, and in your case the path argument (2nd parameter of invoke ) is a simple string, too. This is how to do it:

// A string
let string = "foo";

// A matching regex (not the case in the original post)
let regex = /foo/;

// Does it match? Note there's two pairs of [] 
// that shouldn't be there in the original post.
let result = _.invoke(string, "match", regex);

// ["foo"]
console.log(result);

Answer 3

you can just do it in plain Javascript. Try

const regex = /foo/;
const testString = "bar";
if(regex.test(testString)) {
   // code..
}
