I have an html page contain a div called wowslider-container1. I want to recreate the elements inside the wowslider-container1 when the values of properties such as duration and delay change. If I create another slider, it will create multiple sliders. If I hide, both will hide. What can I do? I don't need multiple sliders.
Duration:<input type="number" id="txtDuration" />
Delay<input type="number" id="txtDelay" />
<button onclick="set()">Set </button>
<br/>
<br/>
<div>
<div id="wowslider-container1">
<div class="ws_images">
<ul>
<li>
<a href='SBG_ANA2019_Brochure.pdf' target='_blank' title='Consign.' style="cursor: pointer">
<img id="wows1_0" class="imgMain" src="SBG_HomePg_ANA2019_1146x405V3.jpg" len="0" alt="Consign." />
</a>
</li>
</ul>
</div>
</div>
</div>
script
var delay_value=100;
var duration_value=20;
function set() {
var dur=document.getElementById("txtDuration").value;
var del=document.getElementById("txtDelay").value;
setDuration(del, dur);
}
function setDuration(delay,duration) {
delay_value=delay;
duration_value=duration;
jQuery("#wowslider-container1").wowSlider({
effect: "fade",
prev: "",
next: "",
duration: duration_value * 100,
delay: delay_value * 100,
width: 900, height: 640,
autoPlay: true,
autoPlayVideo: false,
playPause: true,
stopOnHover: false,
loop: false,
bullets: 0,
caption: false,
captionEffect: "parallax",
controls: true,
controlsThumb: false,
responsive: 1,
fullScreen: false,
gestures: 2,
onBeforeStep: 0,
images: 0
});
}
setDuration(20,100);
The API shows that options can only be set during slider initialization (and there's no destroy() event), so you'll have to remove the events / elements and restart the slider:

I have bxSlider integrated in an existing application showing three different slides.
Each slide contains a HTML canvas which is periodically updated with a new JCharts graph.
It works perfect! Only... the last slide does appear, but does not show the content of the canvas.
The following bxSlider element is used. In this case the canvas with id loadedClassesLineChart is showm, but does not show the graph. When i change the order of the tags the content of the last canvas is not shown (although the canvas is shown an a pager is shown with 3 dots)
<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>
When adding an extra empty <li> </li> after the last </li> all three graphs are shown and the fourth empty slide is shown.
bxSlider is started using the document ready function.
$(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();
});
});
What i have tried;
UseCSS : false
slideWidth : 200
minSlides : different values
maxSlides : different values
adaptiveHeight: false
reproducable on FireFox, Safari and Opera
Anyone able to help me out on this one ?
The problem was, the plugin bxslider clones some of the elements(<li></li>) which has canvas as child. So the canvas inside newly cloned element is NOT initialized using ChartJS
I have modified the code a little bit to support this.
// 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]}]}, {

function refreshHeapUsageBarChart() {
$('.heapSizeStackedBarChart').replaceWith('<canvas class="heapSizeStackedBarChart" width="200" height="200" style="margin: 0px 0px 0px 0px;"></canvas>');

or simply set onSlideAfter reload where 3000 mean time how long to wait till reload from start (infinitiLoop must be false):
infiniteLoop: false,
onSlideAfter: function(){
setTimeout(function(){_this.reloadSlider()},3000);
}
