无法在提交时从HTML表单获取jQuery中的值

问题描述：

I'm still working on things and I've almost got it done. The only issue I've got is in my jQuery code it don't send values to a php page. Ex: it should put "?whatever=whatever&soon=soon", but it don't. It leaves it blank.

I've tried changing code such as changing JS ids, and changing the code completely.

$(document).ready(function() {
var $userName = $("username");
var $text = $("text");
var $title = $("title");
var $chatSend = $("#chatSend");

function secret() {
    var userNameString = $userName.val();
    var textString = $text.val();
    var titleString = $title.val();

    $.get("./upload.php", {
        username: userNameString,
        text: textString,
        title: titleString
    });

    window.location.replace("success.php");

    }
}

I expected it to put in my values (to my MySQL table), but instead they're all blank.

Here's my form. (When clicked on chatSend, it does the jQuery functions.)

<div>
<input type="text" id="text" name="text">
                <input type="text" id="title" name="title">
                <input type="text" id="username" name="username" hidden value="<?php echo htmlspecialchars($_SESSION['username']); ?>">
                <button id="chatSend">Send</button>
</div>

Also, here's the upload form now that I think about it (upload.php):

$user = $_GET['username'];

$title = $_GET['title'];

$text = $_GET['text'];

$query = mysqli_query($con, "INSERT INTO `blog` (username, title, text, view) VALUES ('$user', '$title', '$text', UUID())");

我还在处理事情，我差不多完成了。我唯一的问题是在我的jQuery代码中它不会将值发送到php页面。例如：它应该放“不管怎么样？很快就会很快”，但事实并非如此。它留空了。 p>

我尝试更改代码，例如更改JS ID，以及完全更改代码。 p>

  $（ 文件）.ready（function（）{
var $ userName = $（“username”）; 
var $ text = $（“text”）; 
var $ title = $（“title”）; 
var $ chatSend =  $（“＃chatSend”）; 
 
function secret（）{
 var userNameString = $ userName.val（）; 
 var textString = $ text.val（）; 
 var titleString = $ title.val（  ）; 
 
 $ .get（“./ upload.php”，{
用户名：userNameString，
 text：textString，
 title：titleString 
}）; 
 
 window.location.replace  （“success.php”）; 
 
} 
} 
  code>  pre> 
 
 我希望它放入我的值（到我的MySQL表），而是 它们都是空白的。 p> 
 
 
这是我的表格。（当点击chatSend时，它会执行jQuery函数。） p> 
 
 
 ＆lt;  div＆gt; 
＆lt; input type =“text”id =“text”name =“text”＆gt; 
＆lt; input type =“text”id =“title”name =“title”＆gt; 
＆lt; input  type =“text”id =“username”nam  e =“username”hidden value =“＆lt;？php echo htmlspecialchars（$ _ SESSION ['username']）;  ？＆gt;“＆gt; 
＆lt; button id =”chatSend“＆gt;发送＆lt; /按钮＆gt; 
＆lt; / div＆gt; 
  code>  pre> 
 
 此外，这是 现在上传表格我想到了它（upload.php）： p> 
 
 
  $ user = $ _GET ['username']; 
 
 $ title = $ _GET ['  title']; 
 
 $ text = $ _GET ['text']; 
 
 $ query = mysqli_query（$ con，“INSERT INTO`blog`（用户名，标题，文字，视图）VALUES（'$  user'，'$ title'，'$ text'，UUID（））“）; 
  code>  pre> 
  div>

答

You need to use the proper identifier like you have with chatsend:

//# = ID
var $userName = $("#username");
var $text = $("#text");
var $title = $("#title");
