Morris.js 图表在 bootstrap 选项卡中不起作用
Morris.js chart not working inside of a bootstrap tab
我有一种情况,我试图在两个不同的 bootstrap tabs 中使用 MorrisJS 图表。图表在第一个(默认)选项卡中加载正常,但当我单击第二个选项卡时,图表根本无法正确加载。这很奇怪,因为我将完全相同的图表复制并粘贴到第一个和第二个选项卡中,但我没有加载第二个图表。
这是我设置的 jsfiddle link。 https://jsfiddle.net/phz0e68d/5/
代码如下:
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>
Javascript:
Morris.Bar({
element: 'chart1',
data: [
{ y: '2006', a: 100, b: 90 },
{ y: '2007', a: 75, b: 65 },

{ 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:
第二张图表如下所示:
如您所见,第二张图表根本没有正确加载。控制台中出现关于负宽度的错误,但我不确定这是怎么可能的。
将 Morris.Bar 属性 resize
设置为真:
resize: true
将您的 Morris.Bar 分配给一个变量:
var homeBar = Morris.Bar({...});
var profileBar = Morris.Bar({...});
添加一个在选项卡更改时触发的事件,该事件会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;
}
});

var homeBar = Morris.Bar({
element: 'chart1',
data: [
{ y: '2006', a: 100, b: 90 },
