我使用Ziptastic，但我收到此错误：

未捕获的Ref​​erenceError：日期不定义

  statezip = statezip（）;
警报（statezip）;

功能statezip（）{
    VAR twostate;
    $阿贾克斯（{
        网址：http://zip.elevenbasetwo.com/v2/US/10010
        数据类型：JSON，
        异步：假的，
        数据： {}，
        成功：功能（数据）{
            twostate = date.state;
            返回twostate;
        }
    }）;
}
 

为什么我得到这个错误？

您有一个错字在

  date.state
 

这应该是：

  data.state
 

顺便说这是不建议使用

 异步：假的
 

由于所有的JavaScript正在等待Ajax请求有响应。它会减慢你的应用程序，绝对不是用它一个很好的做法。

I am using Ziptastic, but I'm receiving this error:

Uncaught ReferenceError: date is not defined

statezip = statezip();
alert(statezip);

function statezip() {
    var twostate;
    $.ajax({
        url: "http://zip.elevenbasetwo.com/v2/US/10010",
        dataType: 'json',
        async: false,
        data: {},
        success: function (data) {
            twostate = date.state;
            return twostate;
        }
    });
}

Why do I get this error?

You have a typo at

date.state

It should be:

data.state

By the way it is not suggested to use

async: false

As all the JavaScript is waiting for the ajax request to have a response. It will slow down your application and definitely is not a good practice to use it.
