获取api key java脚本的未捕获错误

Question

在我的网页中，我想为用户输入的位置提供自动填充功能。 为此，我使用了一些函数并计算了它对静态值有效的距离。

工作代码：

inplace=True

我在这里使用了javascript距离函数来计算距离。 但是现在我需要使用一个能够返回距离的php函数。我在会话中存储了一些纬度经度值，我试图检索并计算距离但是当我添加此代码时，我收到了api密钥未被捕获的错误，并且它表示initAutocomplete不是函数。

<script>


    // This example displays an address form, using the autocomplete feature
    // of the Google Places API to help users fill in the information.

    // This example requires the Places library. Include the libraries=places
    // parameter when you first load the API. For example:
    // <script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places">

此代码无效。我正在使用代码点火器框架。我没有得到这个，请帮忙。谢谢..
