将JavaScript内容放置在Bootstrap Popover中

我在将JavaScript放入Popover时遇到问题.我想在单击时将来自Chart.js的图形放在Popover内部.为了便于说明,请使用文档http://www.chartjs.org/docs/latest/中的示例图

到目前为止,我有我的Popover-

<button type="button" 
        class="btn btn-lg btn-primary" 
        data-toggle="popover" 
        title="Good vs. Evil Winrate" 
        data-placement="bottom" 
        data-content="Graph coming soon!">
    Who's Winning?
</button>

然后用jQuery对其进行初始化-

$(document).ready(function(){
    $('[data-toggle="popover"]').popover();
});

我只是不明白如何将图形放置在Popover中,我尝试过的所有操作都将其破坏到Popover根本无法打开的地步.

解决方法:

您可以直接设置popover options in JavaScript,也可以收听事件.

此处的重要选项是html：true,它允许将HTML放置在弹出窗口内容中,否则显示为字符串.

content option documentation指出：

Default content value if data-content attribute isn’t present.

然后,聆听show.bs.popover事件,我们得到先前放置的< canvas>使用jQuery,并将其作为新Chart.js实例的上下文传递.

$('[data-toggle="popover"]').popover({
  html: true,
  content: '<canvas id="myChart" width="400" height="400"></canvas>',
}).on('shown.bs.popover', function() {

  new Chart($('#myChart'), {
    // The type of chart we want to create
    type: 'line',

    // The data for our dataset
    data: {
      labels: ["January", "February", "March", "April", "May", "June", "July"],
      datasets: [{
        label: "My First dataset",
        backgroundColor: 'rgb(255, 99, 132)',
        borderColor: 'rgb(255, 99, 132)',
        data: [0, 10, 5, 2, 20, 30, 45],
      }]
    },

    // Configuration options go here
    options: {}
  });
});

<button type="button" class="btn btn-lg btn-primary" data-toggle="popover" title="Good vs. Evil Winrate" data-placement="bottom">Who's Winning?</button>
