You can utilize the val() method to test or else check if inputs remain empty within jQuery. The below example which will add a green outline around the inputs if it is focused but not filled.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Checking for Empty Value in jQuery</title>
<style>
.error{
outline: 1px solid yellow;
}
</style>
<script src="https://code.jquery.com/jquery-1.12.4.min.js"></script>
<script>
$(document).ready(function(){
$('#myForm input[type="text"]').blur(function(){
if(!$(this).val()){
$(this).addClass("error");
} else{
$(this).removeClass("error");
}
});
});
</script>
</head>
<body>
<form id="myForm">
<p><label>Name: <input type="text"></label></p>
<p><label>Position: <input type="text"></label></p>
<p><label>Email Address: <input type="text"></label></p>
