Regex Issue, Restricting '*' Character

I have a text area, where I am allowing only a-z characters and number, with some special characters (like (, ), \, _). My regex looks like: /[^a-zA-Z0-9()-\/\\_ ]/g and my javasc

Solution 1:

You need to escape the - in the regexp:

/[^a-zA-Z0-9()\-\/\\_ ]/

Otherwise, you're matching all the characters between ) and /: *+,-.

See the ASCII Table to see what characters are in a range.

Solution 2:

Use this regex to to include * also in your search:

[^a-zA-Z0-9()\-\/\\_ ]{0,1}[*]

Solution 3:

Try this:

functioncheckValue (eleValue) {
    var re = newRegExp(/[a-z0-9\(\)\/\\_\s]+/ig);
    return re.test(eleValue);
}
