Question

我试图让我的谷歌图表响应。谷歌图表位于bootstrap模式。

javascript代码：

 var jsonData = $.ajax({
        url: "testChart.php",
        dataType: "json",
        async: false
    }).responseText;


    var data = new google.visualization.DataTable(jsonData);

    var options = {
        chart: {
            title: 'Values',
        },
        width: 900,
        height: 600
    };

    //var chart = new google.charts.Line(document.getElementById('chart_div'));
    var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
    //chart.draw(data, google.charts.Line.convertOptions(options));
    chart.draw(data, options);

    $('#chartModal').modal("show");

HTML代码：

<div id="chartModal" class="modal fade">
<div class="modal-dialog">
    <div class="modal-content">
        <div class="modal-header">
            <h4 class="modal-title">Chart</h4>
        </div>
        <div class="modal-body" id="chart_details">
            <div id="chart_div"></div>
        </div>
        <div class="modal-footer">
            <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        </div>
    </div>
</div>

电话模式中的图表图像＆＃34;现在：

*我已尝试以百分比形式在javascript中创建宽度和高度值，但无效。

Answer 1

图表将遵循其容器的大小
但只有当容器可见时

因此，需要等到模态显示，
在绘制图表之前

听这个事件 - ＆gt; 'shown.bs.modal'

请参阅以下工作代码段...
