javascript - 通过点击标签来充值

Question

我需要通过单击链接重新加载选项卡的内容，因为我正在尝试 rendering Google Chart 上的问题.

我做了一个JsFiddle这代表了问题所在。请注意两个选项卡的渲染差异。

我设置了延迟，但是当我访问另一个选项卡时。错误的渲染仍然会发生。

setTimeout(function () {
            chart.draw(data, options);
        }, 2000);

Answer 1

第一次绘制之前需要等到图表的容器可见

请参阅以下工作片段...

$(document).foundation();

$('#sac-tabs').on('change.zf.tabs', function() {
  switch ($(this).children('.is-active').text().trim()) {
    case 'Tab 1':
      drawVisualization();
      break;

    case 'Tab 2':
      drawVisualization2();
      break;
  }
});

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

function drawVisualization() {
    var data = google.visualization.arrayToDataTable([
        ['Departamento', 'Concluídas', 'Andamento', 'Pendentes'],
        ['Vendas', 5, 6, 2],
        ['Peças', 3, 4, 6],
        ['Serviços', 1, 2, 3],
        ['Administrativo', 7, 5, 3]
    ]);

    var options = {
        title: 'Gráfico',
        hAxis: {title: 'Departamento'},
        seriesType: 'bars',
        colors: ['#21BA45', '#F90', '#DC3912'],
        series: {5: {type: 'line'}}
    };

    var chart = new google.visualization.ComboChart(document.getElementById('chart_div'));
    chart.draw(data, options);
}

function drawVisualization2() {
    var data = google.visualization.arrayToDataTable([
        ['Departamento', 'Concluídas', 'Andamento', 'Pendentes'],
        ['Vendas', 5, 6, 2],
        ['Peças', 3, 4, 6],
        ['Serviços', 1, 2, 3],
        ['Administrativo', 7, 5, 3]
    ]);

    var options = {
        title: 'Gráfico',
        hAxis: {title: 'Departamento'},
        seriesType: 'bars',
        colors: ['#21BA45', '#F90', '#DC3912'],
        series: {5: {type: 'line'}}
    };

    var chart = new google.visualization.ComboChart(document.getElementById('chart_div2'));
    chart.draw(data, options);
};
