我的HTML代码是：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<title>form practice</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>

$(document).ready(function(){
$("#dob").change(function(){
var value = $("#dob").val();
var dob = new Date(value);
var today = new Date();
var age = Math.floor((today-dob) / (365.25 * 24 * 60 * 60 * 1000));
if(isNaN(age)) {
// will set 0 when value will be NaN
age=0;
}
else {
age=age;
}
$('#age').val(age);
});
});

我在MySQLi数据库中存储数据的PHP代码是：
And my PHP code that stores the data in the MySQLi database is:
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "testdb";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
if (isset($_POST['submitForm2'])) {
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$dob = $_POST['dob'];
$age = $_POST['age'];
$profilepic = $_POST['profilepic'];
$sql = "INSERT INTO info (firstname, lastname, dob, age, profilepic)
VALUES ('{$firstname}', '{$lastname}', '{$dob}', '{$age}', '{$profilepic}')";
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
} else {
echo "Are you sure you enter a firstname and the name of your html submit
is submitForm";
}
$conn->close();
?>
我在互联网上看到很多教程使用AJAX来实现这样的可视化结果但似乎是我的编码水平很难！有没有一种简单的方法在我的代码中在图像输入元素上方显示带有虚拟图片的边框？
I've seen many tutorials on the internet using AJAX to achieve such a visualised result but it seems a kind of difficult for my coding level! Is there a simple way to display a border with a dummy picture above the image input element in my code?
推荐答案
只是一个想法，用你的代码试试这个
Just an idea, Try this with your code
$('input[type=file]').change(function () {
$('#dummyImg').attr('src',URL.createObjectURL(event.target.files[0]));
});
#dummyImg{width:100%;}
.img-block{border:2px solid cyan;width:400px;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="img-block">
<img src="" id="dummyImg" />
</div>
<label for="profilepic">Profile Picture:</label>
<input type="file" id="profilepic" name="profilepic" accept="image/*" placeholder="Όνομα Πελάτη.." border="5"><br><br>
<input type="submit" name="submitForm2" value="Submit" />
