Check for e-mail values before submitting - actionscript-3

Question

Before submitting the form I need a function to check for # and . symbols.
Function responsible for checking that values are inserted:
// function ValidateAndSend
function ValidateAndSend (event:MouseEvent):void {
// validate fields
if(!name_txt.length) {
status_txt.text = "Please enter your name";
} else if (!email_txt.length) {
status_txt.text = "Please enter your e-mail address";
} else if (!phone_txt.length) {
status_txt.text = "Please enter your phone number";
} else {
// All is good, send the data now to PHP
// ready the variables in our form for sending
variables.userName = name_txt.text;
variables.userEmail = email_txt.text;
variables.userPhone = phone_txt.text;
variables.userShop = shopList.value;
// Send the data to PHP now
varLoader.load(varSend);
} // close else condition for error handling
} // close validate and send function
I've tried creating a separate function for checking the e-mail symbols:
// Checking e-mail
function checkEmail():Boolean {
var reEmail:String = email_txt.text;
var emailOk:Boolean = false;
var checkArray1:Array = reEmail.split("#");
if (checkArray1.length >1) {
var checkArray2:Array = checkArray1[1].split(".");
if (checkArray2.length >1) {
emailOk = true;
}
}
return emailOk;
}
but this doesn't work. How would you achieve this?
Update: I've tried running the function inside ValidateAndSend function. But now if the email address is wrong it won't send the message but it still displays a successful submitting message.
// function ValidateAndSend
function ValidateAndSend (event:MouseEvent):void {
// validate fields
if(!name_txt.length) {
status_txt.text = "Please enter your name";
} else if (!email_txt.length) {
status_txt.text = "Please enter your e-mail";
// Checking e-mail
function checkEmail():Boolean {
var reEmail:String = email_txt.text;
var emailOk:Boolean = false;
var checkArray1:Array = reEmail.split("#");
if (checkArray1.length >1) {
status_txt.text = "Please check your e-mail address";
var checkArray2:Array = checkArray1[1].split(".");
if (checkArray2.length >1) {
emailOk = true;
}
}
return emailOk;
}
} else if (!phone_txt.length) {
status_txt.text = "Please enter your phone number";
} else {
// All is good, send the data now to PHP
// ready the variables in our form for sending
variables.userName = name_txt.text;
variables.userEmail = email_txt.text;
variables.userPhone = phone_txt.text;
variables.userShop = shopList.value;
// Send the data to PHP now
varLoader.load(varSend);
} // close else condition for error handling
} // close validate and send function

You should use regular expressions for this.
Your checkEmail() function won't be needed
// function ValidateAndSend
function ValidateAndSend (event:MouseEvent):void {
var emailCheckRegExp:RegExp = /^[\w.-]+#\w[\w.-]+\.[\w.-]*[a-z][a-z]$/i;
// validate fields
if(name_txt.length == 0) {
status_txt.text = "Please enter your name";
}
else if (email_txt.length == 0) {
status_txt.text = "Please enter your e-mail address";
}
else if (phone_txt.length == 0) {
status_txt.text = "Please enter your phone number";
}
else if(emailCheckRegExp.exec(email_txt.text) == null)
{
status_txt.text = "Entered e-mail is not valid";
}
else {
// All is good, send the data now to PHP
// ready the variables in our form for sending
variables.userName = name_txt.text;
variables.userEmail = email_txt.text;
variables.userPhone = phone_txt.text;
variables.userShop = shopList.value;
// Send the data to PHP now
varLoader.load(varSend);
} // close else condition for error handling
} // close validate and send function
