Question

当我点击确定没有任何反应时，我正在使用谷歌可视化图表尝试图表，控制台显示错误：

TypeError：a不是函数

我正在使用的代码如下：

<script type="text/javascript">
google.load('visualization', '1', { packages: ['corechart', 'controls', 'charteditor'] });
google.setOnLoadCallback(drawChart);
window.addEventListener('resize', redrawChart, false);

var chart;

function drawChart() {
    var data = new google.visualization.DataTable(GetData());

    var columnsTable = new google.visualization.DataTable();
    columnsTable.addColumn('number', 'colIndex');
    columnsTable.addColumn('string', 'colLabel');
    var initState = { selectedValues: [] };
    // put the columns into this data table (skip column 0)
    for (var i = 1; i < data.getNumberOfColumns(); i++) {
        columnsTable.addRow([i, data.getColumnLabel(i)]);
        // you can comment out this next line if you want to have a default selection other than the whole list
        initState.selectedValues.push(data.getColumnLabel(i));
    }
    // you can set individual columns to be the default columns (instead of populating via the loop above) like this:
    // initState.selectedValues.push(data.getColumnLabel(4));

    chart = new google.visualization.ChartWrapper({
        chartType: 'LineChart',
        containerId: 'chart_div',
        dataTable: data,
        options: {
            title: 'Number In Treatment'
        }
    });

    var chartEditor = new google.visualization.ChartEditor();
    google.visualization.events.addListener(chartEditor, 'ok', data);
    chartEditor.openDialog(chart, {});
    chart = chartEditor.getChartWrapper();
    redrawChart();

    var columnFilter = new google.visualization.ControlWrapper({
        controlType: 'CategoryFilter',
        containerId: 'filter_div',
        dataTable: columnsTable,
        options: {
            filterColumnLabel: 'colLabel',
            ui: {
                label: 'Columns',
                allowTyping: false,
                allowMultiple: true,
                allowNone: false,
                selectedValuesLayout: 'belowStacked'
            }
        },
        state: initState
    });

    var width = Math.min(document.documentElement.clientWidth, window.innerWidth || 0) + 'px';

    chart.setOption('height', '200px');
    chart.setOption('width', width);

    setChartView();

    function setChartView() {
        var state = columnFilter.getState();
        var row;
        var view = {
            columns: [0]
        };
        for (var i = 0; i < state.selectedValues.length; i++) {
            row = columnsTable.getFilteredRows([{ column: 1, value: state.selectedValues[i] }])[0];
            view.columns.push(columnsTable.getValue(row, 0));
        }
        // sort the indices into their original order
        view.columns.sort(function (a, b) {
            return (a - b);
        });
        chart.setView(view);
        chart.draw();
    }


    google.visualization.events.addListener(columnFilter, 'statechange', setChartView);

    setChartView();
    columnFilter.draw();
}

function redrawChart() {

    var width = Math.min(document.documentElement.clientWidth, window.innerWidth || 0) + 'px';

    chart.setOption('height', '200px');
    chart.setOption('width', width);

    chart.draw();
}

单击“确定”按钮后，如何重新绘制图表？

Answer 1

'ok'事件的最后一个参数应该是对回调函数的引用 - 而不是data

请参阅以下代码段，getWrapper作为回调传递触发时，请使用getChartWrapper

var chartEditor = new google.visualization.ChartEditor();
google.visualization.events.addListener(chartEditor, 'ok', getWrapper);
chartEditor.openDialog(chart, {});

function getWrapper() {
  chart = chartEditor.getChartWrapper();
  redrawChart();
}

请参阅以下工作代码段...

<div id="chart_div"></div>
<div id="filter_div"></div>

＆＃13;

注意：建议使用https://www.gstatic.com/charts/loader.js加载库，而不是jsapi

根据release notes ...

通过 jsapi 加载程序保留的Google Charts版本不再一致地更新。从现在开始，请使用新的 gstatic 加载程序。

这只会更改load语句，请参阅上面的代码段...
