Morris.js图表​​在引导选项卡内部不起作用

Question

我有一种情况,我试图在两个不同的引导选项卡中使用MorrisJS图表.图表在第一个(默认)选项卡中加载正常,但是当我单击第二个选项卡时,图表根本无法正确加载.这是非常奇怪的,因为我复制并粘贴完全相同的图表在第一个和第二个选项卡中,但第二个没有为我加载.

这是我设置的jsfiddle的链接.https://jsfiddle.net/phz0e68d/5/

这是代码:

HTML:

<div>   
    <!-- Nav tabs -->
    <ul class="nav nav-tabs" role="tablist">
        <li role="presentation" class="active"><a href="#home" aria-controls="home" role="tab" data-toggle="tab">Home</a></li>
        <li role="presentation"><a href="#profile" aria-controls="profile" role="tab" data-toggle="tab">Profile</a></li>
    </ul>

    <!-- Tab panes -->
    <div class="tab-content">
        <div role="tabpanel" class="tab-pane active" id="home">
            <div class="row">
                <div class="col-md-12">
                    <div id="chart1" style="height: 200px;"></div>
                </div>
            </div>
        </div>
        <div role="tabpanel" class="tab-pane" id="profile">
            <div class="row">
                <div class="col-md-12">
                    <div id="chart2" style="height: 200px;"></div>
                </div>
            </div>
        </div>
    </div>
</div>

使用Javascript:

Morris.Bar({
  element: 'chart1',
  data: [
    { y: '2006', a: 100, b: 90 },
    { y: '2007', a: 75,  b: 65 },
    { y: '2008', a: 50,  b: 40 },
    { y: '2009', a: 75,  b: 65 },
    { y: '2010', a: 50,  b: 40 },
    { y: '2011', a: 75,  b: 65 },
    { y: '2012', a: 100, b: 90 }
  ],
  xkey: 'y',
  ykeys: ['a', 'b'],
  labels: ['Series A', 'Series B'],
  hideHover: 'always'
});

Morris.Bar({
  element: 'chart2',
  data: [
    { y: '2006', a: 100, b: 90 },
    { y: '2007', a: 75,  b: 65 },
    { y: '2008', a: 50,  b: 40 },
    { y: '2009', a: 75,  b: 65 },
    { y: '2010', a: 50,  b: 40 },
    { y: '2011', a: 75,  b: 65 },
    { y: '2012', a: 100, b: 90 }
  ],
  xkey: 'y',
  ykeys: ['a', 'b'],
  labels: ['Series A', 'Series B'],
  hideHover: 'always'
});

第一个图表如下所示:

第二个图表如下所示:

如您所见,第二张图表根本没有正确加载.控制台中有一个关于负宽度的错误,但我不确定这是怎么回事.

将Morris.Bar属性设置resize为true:

resize: true

将您的Morris.Bar分配给变量:

var homeBar = Morris.Bar({...});
var profileBar = Morris.Bar({...});

添加在制表符更改时触发的事件,重绘条形图并触发调整大小:

$('a[data-toggle="tab"]').on('shown.bs.tab', function(e) {
  var target = $(e.target).attr("href") // activated tab

  switch (target) {
    case "#home":
      homeBar.redraw();
      $(window).trigger('resize');
      break;
    case "#profile":
      profileBar.redraw();
      $(window).trigger('resize');
      break;
  }
});

请参阅下面的完整工作代码段:

var homeBar = Morris.Bar({
  element: 'chart1',
  data: [
    { y: '2006', a: 100, b: 90 },
    { y: '2007', a: 75, b: 65 },
    { y: '2008', a: 50, b: 40 },
    { y: '2009', a: 75, b: 65 },
    { y: '2010', a: 50, b: 40 },
    { y: '2011', a: 75, b: 65 },
    { y: '2012', a: 100, b: 90 }
  ],
  xkey: 'y',
  ykeys: ['a', 'b'],
  labels: ['Series A', 'Series B'],
  hideHover: 'always',
  resize: true
});

var profileBar = Morris.Bar({
  element: 'chart2',
  data: [
    { y: '2006', a: 100, b: 90 },
    { y: '2007', a: 75, b: 65 },
    { y: '2008', a: 50, b: 40 },
    { y: '2009', a: 75, b: 65 },
    { y: '2010', a: 50, b: 40 },
    { y: '2011', a: 75, b: 65 },
    { y: '2012', a: 100, b: 90 }
  ],
  xkey: 'y',
  ykeys: ['a', 'b'],
  labels: ['Series A', 'Series B'],
  hideHover: 'always',
  resize: true
});

$('a[data-toggle="tab"]').on('shown.bs.tab', function(e) {
  var target = $(e.target).attr("href") // activated tab

  switch (target) {
    case "#home":
      homeBar.redraw();
      $(window).trigger('resize');
      break;
    case "#profile":
      profileBar.redraw();
      $(window).trigger('resize');
      break;
  }
});
