I'm trying to validate a textbox to see if it contains numbers and special characters, but for some reason, my code doesn't seem to work:
<script>
function validation(){
var firstname = $("#Fname").val();
if(firstname.match(/^[A-Za-z]*/)){
return true;
}
else{
alert("Invalid name!");
return false;
}
};
</script>
And here is where I called the function:
<form method="POST" action="confirmReservation.php" onSubmit="return validation()" name ="frm">
<div class="col-md-2 form-group">
<br><input type="text" id = "Fname" name="Fname" class="form-control" placeholder="First Name" required>
</div>
</form>
What might be the problem in my code?
You can do as following using jquery:
var str = $('#Search').val();
if(/^[a-zA-Z0-9- ]*$/.test(str) == false) {
alert('Your search string contains illegal characters.');
}
