如何更新Google地图引擎表?

我在Google Maps Engine中有一个表格,我想在Google网站上使用JavaScript动态更新。我找到了this帮助页面,解释了如何将功能附加到现有表中,但我正在努力弄清楚如何修改代码以便它更新表而不是附加到它。我相信我特别需要修改processResponseprocessErrorResponse函数。但是,我对JavaScript / jQuery / JSON还不熟悉,而且我不确定如何确定我应该拥有的内容而不是#insert-table-features-response。这里有人可以向我解释一下吗?

修改:换句话说,如何使用JavaScript制作下面显示的请求?

POST https://www.googleapis.com/mapsengine/v1/tables/{YOUR_TABLE_KEY}/features/batchPatch?key={YOUR_API_KEY}

Content-Type:  application/json
Authorization:  Bearer {. . .}
X-JavaScript-User-Agent:  Google APIs Explorer

{
 "features": [
  {
   "geometry": {
    "type": "Point",
    "coordinates": [
     -82,
     35
    ]
   },
   "properties": {
    "Lat": 35,
    "Long": -82,
    "Name": "6:41:13 AM 11/27/14",
    "gx_id": "123ABC456DEF7890"
   }
  }
 ]
}

我不会试着把它压成对jpatokal答案的评论,而是把它扔进答案。

正如他们所说,您需要使用batchPatch请求,而不是batchInsert。在这里查看文档:{​​{3}}

如果您使用的是文档中提供的JS,那么您链接到的页面上的代码包含此功能:

function insertTableFeatures(tableId) {
  doRequest({
    path: '/mapsengine/v1/tables/' + tableId + '/features/batchInsert',
    method: 'POST',
    body: {
      features: cities
    },
    processResponse: function(response) {
      $('#insert-table-features-response').text(
          JSON.stringify(response, null, 2));
    },
    processErrorResponse: function(response) {
      $('#insert-table-features-response').text('Error response:\n\n' +
          JSON.stringify(response, null, 2));
    }
  });
}

您需要将pathbatchInsert更改为batchPatch并更新body: { ... }。您可以将其替换为您提供的HTTP请求的正文,如下所示:

function updateTableFeatures(tableId) {
  doRequest({
    path: '/mapsengine/v1/tables/' + tableId + '/features/batchPatch',
    method: 'POST',
    body: {
     "features": [
      {
       "geometry": {
        "type": "Point",
        "coordinates": [
         -82,
         35
        ]
       },
       "properties": {
        "Lat": 35,
        "Long": -82,
        "Name": "6:41:13 AM 11/27/14",
        "gx_id": "123ABC456DEF7890"
       }
      }
     ]
    },
    processResponse: function(response) {
      // You'll probably want to change these too
      $('#insert-table-features-response').text(
          JSON.stringify(response, null, 2));
    },
    processErrorResponse: function(response) {
      // You'll probably want to change these too
      $('#insert-table-features-response').text('Error response:\n\n' +
          JSON.stringify(response, null, 2));
    }
  });
}

batchInsert,名称正确,仅插入新功能。请改为batchPatch
