我在现有应用程序中集成了bxSlider,显示了三个不同的幻灯片。 每张幻灯片都包含一个HTML画布,该画布定期使用新的JCharts图更新。 它完美无缺!仅...最后一张幻灯片显示,但不显示画布的内容。
使用以下bxSlider元素。在这种情况下,id为loadedClassesLineChart的画布是showm,但不显示图形。当我更改
<ul class="bxslider" id="rdstats">
<li><p style="background-color:rgb(231, 239, 252);margin-top: -4px;font-weight: bold;padding:6px 6px 6px 6px;">Average CPU Load/CPUs</p><br/>
<canvas id="cpuLoadRadarChart" width="200" height="200" style="margin: 0px 0px 0px 0px;"></canvas>
</li>
<li><p style="background-color:rgb(231, 239, 252);margin-top: -4px;font-weight: bold;padding:6px 6px 6px 6px;">Heapsize allocation</p><br/>
<canvas id="heapSizeStackedBarChart" width="200" height="200" style="margin: 0px 0px 0px 0px;"></canvas>
</li>
<li><p style="background-color:rgb(231, 239, 252);margin-top: -4px;font-weight: bold;padding:6px 6px 6px 6px;">Loaded classes</p><br/>
<canvas id="loadedClassesLineChart" width="200" height="200" style="margin: 0px 0px 0px 0px;"></canvas>
</li>
</ul>
在最后<li> </li>
之后添加额外的空</li>
时,会显示所有三个图表,并显示第四张空幻灯片。
$(document).ready(function() {
$('#rdstats').each(function() {
var _this = $(this).bxSlider({
controls: false,
auto: true,
autoHover: true,
minSlides: 1,
maxSlides: 1,
adaptiveHeight: true,
slidewidth: 200,
slideMargin: 2});
_this.mouseenter(function() {
_this.stopAuto();
}).mouseleave(function() {
_this.startAuto();
});
});
我尝试了什么;
可在FireFox,Safari和Opera上重现
任何人都可以帮我解决这个问题吗?

问题是,插件bxslider
克隆了一些将canvas作为子元素的元素(<li></li>
)。因此,新克隆元素中的画布使用ChartJS
我已经修改了一些代码以支持这一点。
// Refreshes bxslider with id "rdstats" with new data.
function refreshcpuLoadRadarChart() {
// Replace the chart canvas element
$('.cpuLoadRadarChart').replaceWith('<canvas class="cpuLoadRadarChart" width="200" height="200" style="margin: 0px 0px 0px 0px;"></canvas>');
// Get the context of the canvas element we want to select
var ctx = $('.cpuLoadRadarChart').get(0).getContext("2d");
new Chart(ctx).Radar({"labels":["10:54","10:55","10:56","10:57","10:58","10:59","11:00","11:01","11:02","11:03","11:04","11:05","11:06","11:07","11:08","11:09"],"datasets":[{"label":"myserver","fillColor":"rgba(165,222,11,0.2)","strokeColor":"rgba(165,222,11,1)","pointColor":"rgba(165,222,11,1)","pointStrokeColor":"#fff","pointHighlightFill":"#fff","pointHighlightStroke":"rgba(165,222,11,1)","data":[0.03,0.01,0.2,0.53,0.34,0.2,0.43,0.28,0.17,0.28,0.24,0.32,0.2,0.45,0.42,0.15]}]}, {

或简单地设置onSlideAfter reload,其中3000平均时间等待从开始重新加载多长时间(infinitiLoop必须为false):
infiniteLoop: false,
onSlideAfter: function(){
setTimeout(function(){_this.reloadSlider()},3000);
}
