Above is my jsp code.
I want to validate it with JavaScript, but there is no response even if I press the subscribe button.
Please check if the code for validation is correct.
Where do developers usually put their style sheets when working? Do you put it in the jsp?
jsp javascript
<script>
function signUpCheck() {
var form = document.signupform;
if(!form['user-id'].value) {
alert("Please enter your ID");
form['user-id'].focus();
return;
}
alert('success');
}
</script>
Change it like the sauce above.
