在.php中创建Textarea并提交按钮以隐藏数据库表中的每一行?

时间:2022-09-26 10:13:37

Been working on this for long time.. want to add a js effect (hide/unhide) to a simple submit form...

一直在研究这个...想要在简单的提交表单中添加js效果(隐藏/取消隐藏)...

Fortunately it is working but unfortunately it is only working for single row in the DB table.

幸运的是它正在工作,但不幸的是它只适用于DB表中的单行。

I made script:1 (posted below) which was corrected by a well wisher from this site which is script:2 (posted below).

我制作了剧本:1(在下面发布),这是由一个来自这个网站的祝福者纠正的脚本:2(发布在下面)。

unfortunately both are not working. hope you guys help me find the missing peice in it..

不幸的是两个都没有工作。希望你们能帮我找到失踪的阴茎..

Ok so here is your code rewritten, I have not tested it but it should work if your PHP code has no syntax error and your DB is up and running:

好的,所以这里是你的代码重写,我还没有测试过,但是如果你的PHP代码没有语法错误并且你的数据库启动并运行它应该可以工作:

config.php (I added config.php as its just better practice)

config.php(我添加了config.php作为其更好的做法)

<?php
$servername = "localhost";
$username = "root";
$password = "******";
$dbname = "the_database";
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
?>

list.php (this will be your template file and some php logic in there *not the best practice)

list.php(这将是你的模板文件和那里的一些php逻辑*不是最佳实践)

<?php require_once('config.php') ?>

Second Edit

If you need to hide the form when the textarea is out of focus: https://api.jquery.com/focusout/

如果您需要在textarea失焦时隐藏表单:https://api.jquery.com/focusout/

$('.addtext').focusout(function() {
     $(this).parent().fadeOut('slow');
     $(this).parent().parent().find('.add').show();
});

** Third Edit ** Auto Focus on the textarea specifically

**第三次编辑**专门针对textarea进行自动聚焦

    <script type='text/javascript'>
        $(document).ready(function() {
            $('.add').click(function(e) {
                e.preventDefault();
                $(this).parent().find('form').fadeIn('slow');
                $(this).parent().find('form textarea.addtext').focus();
                $(this).hide();
            });
        });

If you need to hide the form when the textarea is out of focus: https://api.jquery.com/focusout/

如果您需要在textarea失焦时隐藏表单:https://api.jquery.com/focusout/

$('.addtext').focusout(function() {
