Javascript Email Validation Specific Domain

Question

I'm trying to get someone to use a specific email domain of @mail.fhsu.edu. Here is my Validation code.

 function validateFHSUEmail(inputField, helpText) {
    if (inputField.value.length == 0) {
        if (helpText != null) {
            helpText.innerHTML = "Please Enter a Value";    
        }
        return false;
    } else {
        var reg = /^[a-z.][email protected]$/;
        if (!reg.test(inputField)) {
            if (helpText != null) {
            helpText.innerHTML = "Please Enter FHSU Email"; 
            }

Am I calling it wrong or what because no matter what it returns false.

FYI, you'll need to change any .s in your regex to \. - . is a special character meaning "any single character can match here". — michaelb958--GoFundMonica

@michaelb958 not inside a [ ] group but otherwise good catch. — Pointy

You're testing the variable "inputField", which apparently is a reference to a DOM element. You want inputField.value in the test.

edit Note the comment wherein it's pointed out that your regex should use \. for the periods in the domain name.

If you want valid email and specific domain try this regex:

/^(([^<>()\[\]\.,;:\s@\"]+(\.[^<>()\[\]\.,;:\s@\"]+)*)|(\".+\"))@domain.com$/
