Google Chart未显示

Question

我正在尝试创建一项功能，当您从下拉列表中选择区域并为其请求降雨数据时，您将获得该数据的Google图表。
但是，它不起作用。
你能看看问题是什么吗？ 对不起的代码提前抱歉。我是JS的新手。我已经对代码进行了评论，以帮助更好地理解它 谢谢:)）

这是fiddle。

这是HTML -

<!-- Some text -->
<div class="text">
    Select a region below to know the annual rainfall in that region.
</div>

<!-- Create dropdown list -->
<div>
    <select class="region">

Answer 1

试试这个

https://jsfiddle.net/15rdener/

这是javascript对象的错误格式

 options = {
             title = "East Madhya Pradesh"
           }

你应该使用

options = {
             title : "East Madhya Pradesh"
          }

Answer 2

做了一些改变......

1. google.load和setOnLoadCallback每个页面加载只应调用一次
2. 将value属性添加到option以避免长if语句
3. 更改query以使用tq=参数，该参数允许sql语句，并仅返回所需的列，而不是整个范围
4. 删除了“获取数据”按钮

修改

1. 图表涵盖了下拉列表 - 归因于float: left;上的css .region 已更改为text-align: left;
2. 增加条形高度 - 使用图表选项bar.groupWidth
3. x轴相差1000 - 使用图表选项hAxis.ticks
   在数组中提供所需的标签
4. y轴显示所有年份，而不仅仅是之间的几个 - 与上述相同，但使用vAxis.ticks
5. 添加评论，让我知道......

见下面的工作片段......

// load google charts, version '45'. 'current' version throws error when loading DataView
google.charts.load('45', {
  // callback function when google finished loading
  'callback': function() {
    jQuery(".region").change(drawChart);
    // removed 'drawChart()', appears you want a selection before drawing
  },
  // packages used on this page
  'packages': ['corechart']
});

function drawChart() {
  // get the selected option value
  var region = jQuery(".region").find(":selected").val();

  // build query with select statement based on region value
  var query = new google.visualization.Query("https://docs.google.com/spreadsheets/d/1wLbWMwwu_bXcpxm8TlkNtkR4gbeqz_o8CuRzdDQMUaM/gviz/tq?gid=799372846&tq=select A," + region);

  // run query
  query.send(handleQueryResponse);
};

function handleQueryResponse(response) {
  // get data table
  var data = response.getDataTable();

  // create number formatter
  var formatter = new google.visualization.NumberFormat({
    pattern: '0'
  });
  // format first column
  formatter.format(data, 0);

  // create number formatter
  var formatter = new google.visualization.NumberFormat({
    pattern: '#,##0.0'
  });
  // format second column
  formatter.format(data, 1);

  // set chart area height
  var chartAreaHeight = data.getNumberOfRows() * 12;

  // set chart height
  var chartHeight = chartAreaHeight + 70;

  // set x-axis labels or 'ticks'
  var xTicks = [];

  // find max amount for ticks
  var dataMax = google.visualization.data.group(
    data,
    // modifier column to find max on entire table
    [{column: 0, type: 'string', modifier: function () {return '';}}],
    // max column
    [{column: 1, type: 'number', aggregation: google.visualization.data.max}]
  );

  // 'round up' to nearest 1000
  var maxTick = Math.ceil(dataMax.getValue(0, 1) / 1000) * 1000;

  // load ticks array
  for (var i = 0; i <= maxTick; i = i + 1000) {
    xTicks.push(i);
  }

  // build y-axis ticks, add every year, need to reduce font or increase height
  var yTicks = [];
  for (var i = 0; i < data.getNumberOfRows(); i++) {
    yTicks.push(data.getValue(i, 0));
  }

  // chart options
  var options = {
    animation: {
      startup: true,
      easing: 'linear',
      duration: 750
    },
    annotations: {
      textStyle: {
        fontSize: 7
      }
    },
    title: jQuery(".region").find(":selected").text(),
    legend: "none",
    vAxis: {
      title: "Year",
      format: "0"
    },
    hAxis: {
      title: "Rainfall (in mm)"
    },
    height: chartHeight,
    chartArea: {
      height: chartAreaHeight,
      // use number for exact, string for percentage "100%"
      top: 70,
      right: 100,
      bottom: 100,
      left: 100
    },
    // set bar height
    bar: {
      groupWidth: 7
    },
    // set x-axis ticks
    hAxis: {
      ticks: xTicks
    },
    // set y-axis options
    vAxis: {
      // format for year
      format: '0',
      // text style, reduce font
      textStyle: {
        fontSize: 8
      },
      // tick marks
      ticks: yTicks
    }
  };

  // create data view from data table
  var view = new google.visualization.DataView(data);
  // add calculated column for annotations, 'current' version bombs here
  view.setColumns([0, 1, {
    calc: "stringify",
    sourceColumn: 1,
    type: "string",
    role: "annotation"
  }]);

  // create, draw chart
  var chart = new google.visualization.BarChart(document.getElementById("chart"));
  chart.draw(view, options);

  // re-draw chart when the window resizes
  // removed 'window.addEventListener' as may not work in older browsers
  $(window).resize(function() {
    chart.draw(view, options);
  });
};

.text {
  margin-bottom: 10px;
}

.region {
  text-align: left;
}

button {
  text-align: left;
  margin-left: 10px;
}
