未捕获的TypeError:尝试通过JQuery发送值时,$(...).value不是函数

未捕获的TypeError:尝试通过JQuery发送值时,$(...).value不是函数

问题描述:

<!DOCTYPE html>
<html>
<head lang="en">
    <script src="https://code.jquery.com/jquery-2.1.4.min.js"></script>
    <meta charset="UTF-8">
    <title>PHP socket chat</title>
    <style>
        * { margin: 0; padding: 0; box-sizing: border-box; }
        body { font: 13px Helvetica, Arial; }
        form { background: #000; padding: 3px; position: fixed; bottom: 0; width: 100%; }
        form input { border: 0; padding: 10px; width: 100%; margin-right: .5%; }
        form button { width: 9%; background: rgb(130, 224, 255); border: none; padding: 10px; }
        #messages { list-style-type: none; margin: 0; padding: 0; }
        #messages li { padding: 5px 10px; }
        #messages li:nth-child(odd) { background: #eee; }
    </style>


</head>
<body>
<ul id="messages"></ul>

<form action="">
    <input type ="text" id="m" autocomplete="off" />
    <input type="submit" value="Submit" onclick="$('#messages').load('send.php', { chat_message: $('#m').value() });" />
</form>

我看到了

未捕获的TypeError:$(...).value不是函数"

"Uncaught TypeError: $(...).value is not a function"

无论何时提交数据,我都不知道为什么.我正在尝试通过POST将文本字段中的数据发送到send.php.

whenever I submit data, and I'm not sure why. I'm trying to send the data in the text field via POST to send.php.

任何帮助将不胜感激,谢谢!

Any help would be appreciated, thanks!

jquery中没有名为value的函数.

There is no function named value in jquery.

{ chat_message: $('#m').value() }

应该是-

$('#m').val()
