Question

我尝试将JSON数据插入Google电子表格。这是我的代码，

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?sensor=false"></script>

<script>
var read=(function(){

data1={
        "jobstatus": [
                      {
                          "dateAndTime": "hi",
                          "jobId": "TCC_tfc",
                          "userId": "admin",
                          "status": "Completed",
                          "jobType": "Excel Upload"
                      }
                  ]
              };
var jobs = data1;
var datae = new google.visualization.DataTable();

datae.addRows(["datetime",jobs.jobstatus.dateAndTime],
          ['jobId', jobs.jobstatus.jobId],
          ['userId', jobs.jobstatus.userId],
          ['status', jobs.jobstatus.status],
          ['jobType', jobs.jobstatus.jobType]
      );});

</script>

执行此代码时出现错误

TypeError：google.visualization未定义

我该如何解决这个错误？我在“SO”中搜索了解决方案，他们说我要添加这一行：

google.load('visualization', '1.0', {'packages':['corechart'], 'callback': read});

通过添加它也会得到同样的错误。有人可以帮助我解决这个问题。

这里有一些建议......

1）建议使用loader.js与旧库jsapi

<script src="https://www.gstatic.com/charts/loader.js"></script>

2）命名callback函数，而不是赋值给变量

google.charts.load('current', {
  callback: read,
  packages:['table']
});

function read(){...}

3）必须在addRows之前添加列，有几种方法可以做到这一点，使用arrayToDataTable很容易

var datae = google.visualization.arrayToDataTable([
  ['datetime', 'jobId', 'userId', 'status', 'jobType'],
]);

4）在data1中，"jobstatus"是一个数组，所以必须使用数组元素索引来访问值

jobs.jobstatus[0].dateAndTime // get first array element with [0]

- 或 -

如果数组中有多个jobstatus，请使用循环将所有内容添加到addRow

jobs.jobstatus.forEach(function (job) {
  datae.addRow([
    job.dateAndTime,
    job.jobId,
    job.userId,
    job.status,
    job.jobType
  ]);
});

请参阅以下工作代码段...

google.charts.load('current', {
  callback: read,
  packages:['table']
});

function read(){
  var data1={
    "jobstatus": [{
      "dateAndTime": "hi",
      "jobId": "TCC_tfc",
      "userId": "admin",
      "status": "Completed",
      "jobType": "Excel Upload"
    }]
  };
  var jobs = data1;

  var datae = google.visualization.arrayToDataTable([
    ['datetime', 'jobId', 'userId', 'status', 'jobType'],
  ]);

  jobs.jobstatus.forEach(function (job) {
    datae.addRow([
      job.dateAndTime,
      job.jobId,
      job.userId,
      job.status,
      job.jobType
    ]);
  });

  var chart = new google.visualization.Table(document.getElementById('chart_div'));
  chart.draw(datae);
}
