AMap is not defined

This error typically occurs in JavaScript when you are trying to use the AMap object, but it has not been defined or loaded properly. AMap is a third-party JavaScript library for maps and location-based services developed by Alibaba.

To fix this error, make sure that you have included the AMap library in your HTML file using a script tag. For example, you can include it like this:

<script src="https://webapi.amap.com/maps?v=1.4.15&key=<your-api-key>"></script>

Make sure to replace `<your-api-key>` with your actual AMap API key.

Also, ensure that your JavaScript code is executed after the AMap library has finished loading. You can do this by wrapping your code in a callback function that is triggered when the AMap library is ready. For example:

<script src="https://webapi.amap.com/maps?v=1.4.15&key=<your-api-key>&callback=initMap"></script>

<script>
  function initMap() {
    // your AMap code here
    var map = new AMap.Map('map-container', {
      center: [116.397428, 39.90923],
      zoom: 13
    });
  }
</script>

This will ensure that the AMap object is defined and available for use in your code.
