I am designing my website and encountering an issue with the email checker. I can't figure out why it's not working, especially since I have never used JavaScript before. This is what I tried:
var flag=true;
var st = Form1["email"].value.indexOf("@");
if (st == -1)
{
alert("You must insert @ in the email address.");
flag=false;
}
If anyone could provide some assistance, I would greatly appreciate it. Thank you for your help!
If you're dealing with email validation, regular expressions can be a lifesaver. Here's an example of how you can use them:
function validateEmailAddress(email) {
var regex = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<()[]\\.,;:\s@"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
return regex.test(email);
}
var emailRegex = /^[0-9a-zA-Z]+([0-9a-zA-Z]*[-._+])*[0-9a-zA-Z]+@[0-9a-zA-Z]+([-.][0-9a-zA-Z]+)*([0-9a-zA-Z]*[.])[a-zA-Z]{2,6}$/;
if (emailRegex.test(Form1["email"].value) == false)
{
alert("The email address you entered is not valid!");
}
