这是一个错误提示,意思是变量名为"data"没有被定义。如果你想使用变量"data",你需要先定义它,并且要保证它在使用之前已经被赋值。你可以检查一下你的代码,看看是否有定义过这个变量,或者在需要它的地方进行定义。

name data is not defined
This error message usually occurs when you try to reference a variable that has not been defined or assigned a value in your code. To fix the error, you need to define the variable before using it in your code. You can also check for any typos in the variable name.
For example, if you have the following code:
```
print(name)
```
You will get a "NameError: name 'name' is not defined" error message because the variable "name" has not been defined. To fix this, you can define the variable by assigning it a value:
```
name = "John"
print(name)
```
This will output "John" without any error message.
ReferenceError: data is not defined
这个错误的原因是因为在代码中使用了一个未定义的变量data。根据引用的信息,可能是在使用jQuery的getJSON方法时没有正确的传递data参数。你可以在函数的括号里添加上data来解决这个问题。例如:
```
$.getJSON('http://127.0.0.1:8000/jQuery-jsonp-server?callback=?',function(data){
$('#result').html(`姓名: ${data.name},<br> 年龄: ${data.age}`);
});
```
这样,就可以成功获取到data的值并使用了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
