Regex validation in java and java scipt for email address
We are using below regular expression to validate email address in java ^[w!#$'*+=?^/_~-]+(.[w!#$'*+=?^/_~-]+)*@([a-zA-Z0-9-]+.)+[AZ]{2,4}$ and it worked fine with invalid email address raju.rathi@gmail.com&^(*&^(*^2 but when I use the same regular expression in javascript , it doesn't work and failes with even valid email addresses . Please suggest what could be root cause of this mismatch?
for eg in javascript , I'm getting false value with below test conditional -
/^[w!#$'*+=?^/~-]+(.[w!#$'*+=?^/~-]+)*@([a-zA-Z0-9-]+.)+ [AZ]{2,4}$/.test("raju.rathi@gmail.com")
You need to convert to in Javascript regex literal:
/^[w!#$'*+=?^/~-]+(.[w!#$'*+=?^/~-]+)*@([a-zA-Z0-9-]+.)+[A-Z]{2,4}$/i.test("raju.rathi@gmail.com")
Also many special regex characters like $ , + , * etc. don't need to be escaped inside character class hence I have removed unnecessary escaping from your character class.
试试这个，它适用于我。
/^[_a-z0-9-]+(.[_a-z0-9-]+)*@[a-z0-9-]+(.[a-z0-9-]+)*(.[a-z]{2,6})$/.test('raju.rathi@gmail.com');
