一、ckeditor界面可以正常插入视频和图表

二、获取代码
（一）通过这个方式获取ckeditor内容

CKEDITOR.instances.editor1.document.getBody().$.innerHTML

（二）获取的内容

"++++++" name="++++++">一、播放视频</h1>

    8,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20width%3D%221588%22%20height%3D%22886%22%3E%3C%2Fsvg%3E" data-cke-real-element-type="video">
    


" name="++++++">二、插入图表

三、新建html显示
（一）相关js和css引入

请问要在html上显示视频和图表，如何设置呀 （ckeditor生成的视频和图表，总不可能在单独的html页面显示不了吧）

自己处理下视频和图标即可，增加下面的代码

<!--图标类库-->
<script src="../ckeditor/plugins/chart/lib/chart.min.js?t=MAUD"></script>
<script>
    ///视频替换
    $('[data-cke-realelement]').replaceWith(function () {
        return decodeURIComponent(this.getAttribute('data-cke-realelement')).replace(/cke:/gi, '')
    });


    function renderChart(canvas, data, legend) {
        var colors =
        {
            // Colors for Bar/Line chart: http://www.chartjs.org/docs/#bar-chart-data-structure
            fillColor: 'rgba(151,187,205,0.5)',
            strokeColor: 'rgba(151,187,205,0.8)',
            highlightFill: 'rgba(151,187,205,0.75)',
            highlightStroke: 'rgba(151,187,205,1)',
            // Colors for Doughnut/Pie/PolarArea charts: http://www.chartjs.org/docs/#doughnut-pie-chart-data-structure
            data: ['#B33131', '#B66F2D', '#B6B330', '#71B232', '#33B22D', '#31B272', '#2DB5B5', '#3172B6', '#3232B6', '#6E31B2', '#B434AF', '#B53071']
        };
        var config = { "Bar": { "animation": false }, "Doughnut": { "animateRotate": false }, "Line": { "animation": false }, "Pie": { "animateRotate": false }, "PolarArea": { "animateRotate": false } };
        var values = data.values,
            chartType = data.chart;
        var i, ctx = canvas.getContext('2d'),
            chart = new Chart(ctx);
        if (chartType != 'bar') {
            for (i = 0; i < values.length; i++) {
                values[i].color = colors.data[i];
                values[i].highlight = colors.data[i];
            }
        }
        if (chartType == 'bar' || chartType == 'line') {
            var data = {
                datasets: [
                    {
                        label: '',
                        fillColor: colors.fillColor,
                        strokeColor: colors.strokeColor,
                        highlightFill: colors.highlightFill,
                        highlightStroke: colors.highlightStroke,
                        data: []
                    }],
                labels: []
            };
            for (i = 0; i < values.length; i++) {
                if (values[i].value) {
                    data.labels.push(values[i].label);
                    data.datasets[0].data.push(values[i].value);
                }
            }
            legend.innerHTML = '';
        }

        if (chartType == 'bar') {
            chart.Bar(data, config.Bar);
        }
        else if (chartType == 'line') {
            chart.Line(data, config.Line);
        }
        else if (chartType == 'polar') {
            legend.innerHTML = chart.PolarArea(values, config.PolarArea).generateLegend();
        }
        else if (chartType == 'pie') {
            legend.innerHTML = chart.Pie(values, config.Pie).generateLegend();
        }
        else {
            legend.innerHTML = chart.Doughnut(values, config.Doughnut).generateLegend();
        }
    }
    $('[data-widget="chart"]').each(function () {
        var el = $(this);
        var data = JSON.parse(decodeURIComponent(el.attr('data-cke-widget-data')));
        var canvas = el.find('canvas')[0];
        var legend = el.find(".chartjs-legend")[0]
        renderChart(canvas, data, legend);
    })
/*  $(function(){
    $("code").each(function(){
