I have a regular expression in java 

^.*(?=.{8,})(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[!()*,/:;<>?\\\]\[\-_`{}~@#$%^&+=]).*$

It matches strings which having these conditions:

  • at least 8 characters
  • at least one digit
  • at least one small letter
  • at least one capital letter

  • at least one special character 

    [!()*,/:;<>?\\\]\[\-_`{}~@#$%^&+=]

How can I convert it into a JavaScript regex?

Reset to default 3

Simple solution with simple regex.

var re = /^(.{0,7}|\D+|[^a-z]+|[^A-Z]+|[^\^!@#$%&\*])$/;
if (!re.test(str)) {
    alert('Matched');
}

Note that there are some missing special characters in my regex.

put two forward slashes around it:

var re = /<your_regex_here>/;

It already works in JavaScript:

var re = /^.*(?=.{8,})(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[!()*,/:;<>?\\\]\[\-_`{}~@#$%^&+=]).*$/;
re.test('abcdefgh0A$') // true
