validate email address from string with jquery working function
Here is a working example of this post validate email address from string.
This has very basic checking of an email address by checking that the string has an @
and a .
in it.
Note: this is still not checking the @ properly still working on this one.
Update: I have split up the checking for the . and the @ as they were conflicting, they are detected now, but still may not give a valid email address check, as it only checks for the existance of the characters rather than their location in the string. So its just very basic validation.
Validate Demo
HTML
<input type="email" id="emailfield" placeholder="Enter Email Address">
<button onclick="validate_email();">Check Email Address</button>
Scripts
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js" referrerpolicy="no-referrer"></script>
Javascript
function validate_email() {
var emailfield = $("#emailfield").val();
var atpos = emailfield.indexOf("@");
var dotpos = emailfield.lastIndexOf(".");
console.log(atpos);
// check the @ 1st
if(atpos >= 1) {} else {
alert("Email missing @");
return false;
}
// check the dot pos
if(dotpos >= 1) {} else {
alert("Email missing .");
return false;
}
alert("Email is valid");
}
