未捕获的ReferenceError:(函数)没有定义

I just think this is useful for people having this problem:

我只是认为这对有这个问题的人是有用的:

I had this code:

我有这段代码:

<html>
<head>
    <link rel="stylesheet" href="example.css" type="text/css"/>
    <title>CSS TESTS</title>
    <script language="text/javascript">
        var move = 0;
    </script>
</head>
<body>
    <input type="text" id="shape" onchange="alert(move);"/>
</body>
</html>

But I couldn't get the alert to work. I would get the Uncaught ReferenceError: move is not defined.

但我无法让警报生效。我将得到未捕获的ReferenceError: move没有定义。

4 个解决方案

It turns out that the language attribute on the script tag did not allow me to specify text/javascript but only javascript. The type attribute allows "text/javascript". That was all and I spent hours trying to find the bug in the javascript code... arg!

原来脚本标记上的语言属性不允许我指定文本/javascript，只允许指定javascript。type属性允许“text/javascript”。就这样，我花了几个小时在javascript代码中寻找bug……参数!

So, basically I changed the line that said

基本上我改变了这条线

<script language="text/javascript">

来

<script type="text/javascript">

and it all worked.

这一切奏效了。

Change <script language="text/javascript"> TO <script type="text/javascript">

工作代码。

<html>
<head>
    <link rel="stylesheet" href="example.css" type="text/css"/>
    <title>CSS TESTS</title>
    <script type="text/javascript">
        var move = 0;
    </script>
</head>
<body>
    <input type="text" id="shape" onchange="alert(move);"/>
</body>
</html>

or do this, here "move" casted as string

或者这样做，这里的“移动”被转换成字符串

<html>
<head>
    <link rel="stylesheet" href="example.css" type="text/css"/>
    <title>CSS TESTS</title>
</head>
<body>
    <input type="text" id="shape" onchange="alert('move');"/>
</body>
</html>

Dont forget to include ,

别忘了包括，

 <script src="jquery-1.xx.x.min.js" type="text/javascript"> </script>

if you are using jquery, xx-x stand for the version you are using.

如果您正在使用jquery，则xx-x代表您正在使用的版本。
