If you know the characters you want to exclude, use a regular expression to replace them with the empty string:

var str = 'The student have 100% of attendance in @school';
console.log(
  str.replace(/[$@%]/g, '')
);

Or, if you don't want to include any special characters at all, decide which characters you do want to include, and use a negative character set instead:

var str = 'The student have 100% of attendance in @school';
console.log(
  str.replace(/[^a-z0-9,. ]/gi, '')
);

The pattern

[^a-z0-9,. ]

means: match any character other than an alphanumeric character, or a comma, or a period, or a space (and it will be replaced with '', the empty string, and removed).

To remove special characters from the string we can use string replace function in javascript.

Eg.

var str = 'The student have 100% of attendance in @school';

alert(str.replace(/[^a-zA-Z ]/g, ""));

This will remove all special character except space

You should explore Regex.

Try this:

var str = 'The student have 100% of attendance in @school';
str=  str.replace(/[^\w\s]/gi, '')
document.write(str);

You can use a regex replace to remove special characters from a string:

str.replace(/[^a-z0-9\s]/gi, '')
