Email query url regex validation-CodePudding

I have an input field that currently has this regex code:

[a-zA-Z0-9._] @[a-zA-Z0-9] .[a-zA-Z]{2,5}

I want to make it so it is able to verify email query URLs, like this:

[email protected]?subject=test%via web.co

Can anyone show me how to go about this?

CodePudding user response：

you can use the regex you have like this:

/[a-zA-Z0-9._] @[a-zA-Z0-9] .[a-zA-Z]{2,5}/.test(<the value of the input field>)

CodePudding user response：

This regex pattern will capture the 2 parts in 2 groups

^([^\s@?%] ?@[^\s@?%] ?\.[A-Za-z]{2,9})(\?[^\s]*)?$

^ : start of the line or string
([^\s@?%] ?@[^\s@?%] ?\.[A-Za-z]{2,9}) : Group 1: the e-mail
(\?[^\s]*)? : optional Group 2: literal question mark and non-whitespace characters after it.
$ : end of the line or string
