在Google Chart API(Javascript)中使用多个工作表

问题描述 投票:0回答:1

在我的Google图表代码中,我使用SELECT函数查询我将使用的行和列的相关Google表格

我相信我使用的查询是SQL,所以考虑到这一点,我使用以下Query来尝试从另一个工作表中选择数据:

SELECT A, B, C, D
FROM 'Sheet 2'

但是出现错误,说语法不正确。下面是图表本身的代码,当代码中没有FROM语法时,它会完美显示:

<head>
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script>
    google.load("visualization", '1', {packages:['corechart', 'bar']});
        google.setOnLoadCallback(drawChart);
        function drawChart() {
          var query = new google.visualization.Query(
              'https://docs.google.com/spreadsheets/d/1oKxlfCjcvjCzGh8fpTX3ax7qWbWA2uVVQgk-jzOWX3k/edit?usp=sharing');
            query.setQuery('SELECT A, B, C, D FROM "Sheet 2"');
          query.send(handleQueryResponse);
        }

        function handleQueryResponse(response) {
          if (response.isError()) {
            alert('Error in query: ' + response.getMessage() + ' ' + response.getDetailedMessage());
            return;
          }

          var data = response.getDataTable();
            for (var i = 0; i < data.getNumberOfColumns(); i++) {
            }
          var chart = new google.visualization.ColumnChart(document.getElementById('columnchart'));
          chart.draw(data);
        }        
        </script>
</head>
    <body>
    <div id='columnchart'></div>
  </body>

如果不是FROM语法,那么如何使用这种创建图表的方法定义多个工作表?

您应该将工作表设置为“gid = 838232320”,而不是在queryString中:

//google.load("visualization", '1', {packages:['corechart', 'bar']});
google.load('visualization', '1.0', {'packages':['corechart'], 'callback': drawChart});
google.setOnLoadCallback(drawChart);


function drawChart() {
  console.log("drawChart: Init");
 var queryString = encodeURIComponent('SELECT A, B, C, D');
 var query = new google.visualization.Query('https://docs.google.com/spreadsheets/d/1oKxlfCjcvjCzGh8fpTX3ax7qWbWA2uVVQgk-jzOWX3k/gviz/tq?gid=838232320&headers=1&tq=' + queryString);
  
  // Apply query language statement.
//  query.setQuery('SELECT A, B, C, D FROM "Sheet 2"');
  
  // Send the query with a callback function.
  query.send(handleQueryResponse);
}

function handleQueryResponse(response) {
  console.log("handleQueryResponse: ", response);
  if (response.isError()) {
    alert('Error in query: ' + response.getMessage() + ' ' + response.getDetailedMessage());
    return;
  }

  var data = response.getDataTable();
  for (var i = 0; i < data.getNumberOfColumns(); i++) {
  }
  var chart = new google.visualization.ColumnChart(document.getElementById('columnchart'));
  chart.draw(data);
}       
<div id='columnchart'></div>
