Check whether a string matches a regex in JS

stackoverflow.com › questions › 6603015 › check-whether-a-string-matches-a-regex-in-js

Use regex.test() if all you want is a boolean result:

console.log(/^([a-z0-9]{5,})$/.test('abc1')); // false

console.log(/^([a-z0-9]{5,})$/.test('abc12')); // true

console.log(/^([a-z0-9]{5,})$/.test('abc123')); // true

...and you could remove the () from your regexp since you've no need for a capture.

RegExp.prototype.test() - JavaScript | MDN

The test() method of RegExp instances executes a search with this regular expression for a match between a regular expression and a specified string. Returns true if there is a match; false otherwise.

Extract Matches VS Test

Tell us what’s happening: I’m curious why when you use test() method, you use the the method as regex.test(str) let regex = /Code/; let result = regex.test(str); When you use match() method, you use the method as str.match(regex) let regex= /Code/; let result = str.match(regex); The only ...

RegEx test method (Javascript)

Whelp, this is not a regex problem, but a Javascript problem. What's happening here is that when you're using the g flag, the regex pattern is "stateful", meaning that it remembers where it left off in the expression when it starts testing another expression. The docs say ... JavaScript RegExp objects are stateful when they have the global or sticky flags set (e.g. /foo/g or /foo/y). They store a lastIndex from the previous match. To fix this, you can either reset the lastIndex or do not use the g flag. Here is a great article that explains it way better than I could More on reddit.com

Test regEx in Javascript.

For the second string, the Regex is actually matching against the middle of the string. Check this out on Regex101 . Specifically, the NPAFRPOX part of BNPAFRPOXXX is matching. You have NPAFRP for 6 capital letters. [A-Z]{6,6} O for a capital letter or number > 1 [A-Z2-9] X for a [A-NP-Z0-9] an alphanumeric besides O And ([A-Z0-9]{3,3}){0,1} is ignored by choosing the 0 option. Do note that, by default, Regex patterns will generally try for any possible match, even if it's not the one you expect. This is why you must add extra control characters and flags to ensure that unexpected behavior doesn't occur. To fix this regex, you might want to add boundary characters ^$ to ensure that the entire string must match, rather than just a substring. So: ^[A-Z]{6,6}[A-Z2-9][A-NP-Z0-9]([A-Z0-9]{3,3}){0,1}$ If you're instead looking for these codes as part of a larger string, perhaps use the word boundary character \b instead. If you can't rely upon word boundaries, you'll have to find a different reliably condition to separate things which are codes from things which are parts of code/noise. Good luck! More on reddit.com
