如何使用jQuery正则表达式验证字符，数字和特殊字符？

Question

I am trying to validate password field such that it accepts characters, numbers and also special characters. It must accept exactly 8 characters . I have searched for it in the internet but I was not able to get any specific answer and if getting its not working.

Let me just give an explanation of the characters the password must accept: AZ, az, 0-9, ~!@#$%^&*()_-+=.|<>?{}[]

So, valid password would be: ankit@19 , a_g-1#87 , etc. Invalid password would be: ag/ i(91 (because it is having space and ' / ' in it)

The regular expression I am using right now is:

/^[A-Za-z0-9?=\.~!@#\$%^&*()_-|<>{}\[\]]{8}$/

This one is not working at all. Please help me to get the right way to do this.

Answer 1

^[A-Za-z0-9?=.~!@#\$%^&*()_|<>{}\[\]-]{8}$

You need to take - at the end and escape [] inside [] .

See demo.
