Regular Expression jquery validation1

Question

Can anybody share Regular Expression below example:

minimum 3 alphanumeric and then add only one '@' then again minimum 3 alphanumeric

example: rohit@tcs or himansu@infosys

Do you want to validate such strings specifically or you want to validate email format ? — Himanshu Upadhyay, Sep 18 '17 at 05:00

Here is a pattern that matches:

/\w{3,}@{1}\w{3,}$/

`\w` matches alphanumeric plus **underscore**. – Tushar Sep 18 '17 at 05:09
This still matches the pattern he's calling for. – Dream_Cap Sep 18 '17 at 05:12

another query : this expression i need only one @ if i added more then one @ then it has been return true – user2686713 Sep 18 '17 at 05:24
I have updated the answer to include only one @. Edited it again, its /\w{3,}@{1}\w{3,}/ – Dream_Cap Sep 18 '17 at 05:26
when i used "alert(/\w{3,}@\w{3,}/.test('333@4449999@@'));" then it should return false but it is returning true. please help – user2686713 Sep 18 '17 at 05:28

I updated the answer to account for the end of the string. – Dream_Cap Sep 18 '17 at 05:31
