how to allow % in regex expression

i have following function where i also want to allow %

for now it is allowing :

//4 special character are allowed.
    //' (single quote)
    //- (hyphen)
    //. (dot)
    //  (single space)

i want to allow 5th charterer there as : %

var RegExPattern = /^[A-Za-z0-9 '.-/%]+$/;
        var str = averageGPACount;
        if (self.averageGPA() != "") {
            if (/^[a-zA-Z0-9- ]*$/.test(str) == false) {
                validationPass = false;
            }
            else {
                $('#txtaverageGPA').removeClass("errorHighlight");
                validationPass = true;
            }
        }

Use this regex: 

var RegExPattern = /^[A-Za-z0-9 '.%-]+$/;
  • hyphen needs to be at 1st or last position to avoid escaping.
  • % doesn't need to be escaped inside a character class.
