How can I remove specific special characters from a string using regex in JavaScript?

This is not a code writing service. What effort have you made to solve this yourself before asking here? — Ken White, Aug 03 '17 at 02:51

*"with the code i tried, i was not able to successfully replace reg and trademark"* - So if you *were* able to replace the other characters there was no need to include them in your question. — nnnnnn, Aug 03 '17 at 03:29

Use the string.replace() method and the unicode escape codes for your special characters. You have to use the \ character to escape in JavaScript regex

var str = 'Here is a \' string \" with \" \' some @ special ® characters ™ & &'
str.replace(/['"\u0040\u0026\u2122\u00ae]/g, '')

/pattern/ denotes a regex pattern in JavaScript

[charset] says which set of characters to match

/g specifies global matches so it will replace all occurrences
