i have problem with wavesurferjs
It is overflowing the parent div
It is happening for the first time and on resize of the parent div
On resize it should fit the parent div
Question: when parent div
is resized waveform
should adjust itself to accomodate
it is shown in the below image:
here is my code:
var wavesurfer = WaveSurfer.create({
container: '#waveform',
// waveColor: 'violet',
waveColor: '#5B88C8',
progressColor: '#264E73',
hideScrollbar: true,
cursor: false,
drag: false
});
wavesurfer.load('https://ia800301.us.archive.org/15/items/fire_and_ice_librivox/fire_and_ice_frost_apc_64kb.mp3');
wavesurfer.enableDragSelection({
drag: false,
slop: 1,
loop : false,
});
wavesurfer.on('region-created', function (region) {
console.log(region.start, region.end);
});
wavesurfer.on('ready', function (readyObj) {
wavesurfer.addRegion({
start: 0, // time in seconds
end: wavesurfer.getDuration(), // time in seconds
color: 'hsla(100, 100%, 30%, 0.1)',
loop: false,
multiple: false,
drag: false
});
})
document.querySelectorAll('wave').forEach(function(wave){
wave.addEventListener('mousedown', function(e) {
e.preventDefault();
wavesurfer.clearRegions();
});
});
$('.toggle-width').on('click',function(){
var width = $('#wavesurferContainer').width();
width = width - 120;
$('#wavesurferContainer').width(width + 'px');
});
handle.wavesurfer-handle{
width: 9% !important;
max-width: 7px !important;
/* background: #03A9F4; */
background: orange;
cursor: default !important;
}
#wavesurferContainer{
width: calc(100% - 50px);
border: 1px solid red;
position: relative;
margin-top: 56px;
}
handle.wavesurfer-handle.wavesurfer-handle-end:before{
bottom: -17px !important;
top: unset !important;
}
#waveform{
margin-top: 10%
}
#waveform wave{
overflow: unset !important;
}
span.toggle-width{
position: relative;
float: right;
}
span.toggle-width:before {

Please help me thanks in advance!!!
The documentation of wavesurfer mentions the responsive
and fillParent
options, which should solve the problem.
reponsive
is available as of waveSurfer v2.0.0 (source), so an upgrade is needed, in case you are using the version 1.2.3
as in the example snippet.
Latest stable version is 3.3.1.
Edit, as a comment mentions that npm is not in use:
The recent builds of the library can be found in a cdns:
Edit2: As documented:
You need to include the plugin's configuration when creating an instance of WaveSurfer:
var wavesurfer = WaveSurfer.create({
container: '#waveform',
plugins: [
WaveSurfer.regions.create({})
]
});
Registering the plugin during the instantiation of wavesurfer solves the problem, as demonstrated in the snippet below.
var wavesurfer = WaveSurfer.create({
container: '#waveform',
// waveColor: 'violet',
waveColor: '#5B88C8',
progressColor: '#264E73',
hideScrollbar: true,
cursor: false,
drag: false,
plugins: [
WaveSurfer.regions.create({})
]
});
wavesurfer.load('https://ia800301.us.archive.org/15/items/fire_and_ice_librivox/fire_and_ice_frost_apc_64kb.mp3');
const resizeObserver = new ResizeObserver(entries => {
for (let entry of entries) {
wavesurfer.empty();
wavesurfer.drawBuffer();
var regs = Object.values(wavesurfer.regions.list);
window.setTimeout(() => {
wavesurfer.regions.clear();
var clear = ({start,end,resize,drag,loop,color}) =>({start,end,resize,drag,loop,color})
regs.forEach(e => wavesurfer.addRegion(clear(e)));
}, 100);
}
});
wavesurfer.enableDragSelection({
drag: false,
slop: 1,
loop : false,
});
wavesurfer.on('region-updated', function (region) {
console.log(region.start, region.end);
});
wavesurfer.on('ready', function (readyObj) {
resizeObserver.observe($('#wavesurferContainer')[0])
wavesurfer.addRegion({
start: 0, // time in seconds
end: wavesurfer.getDuration(), // time in seconds
color: 'hsla(100, 100%, 30%, 0.1)',
loop: false,
multiple: false,
drag: false
});
})
document.querySelectorAll('wave').forEach(function(wave){
wave.addEventListener('mousedown', function(e) {
e.preventDefault();
wavesurfer.clearRegions();
});
});
$(document).on('click','.toggle-width',function(){
console.log('clicked');
var width = $('#wavesurferContainer').width();
width = width - 120;
$('#wavesurferContainer').width(width + 'px');
// you can put here implementation of our redraw.
});
handle.wavesurfer-handle{
width: 9% !important;
max-width: 7px !important;
/* background: #03A9F4; */
background: orange;
cursor: default !important;
}
#wavesurferContainer{
width: calc(100% - 50px);

I found a fix for your current version of wavesurfer.js.
All I did is update drawer size and call redraw method when you change the container width. But then the regions doesn't get updated. So I took the current regions values to a temp variable and removed regions and redraw. Now the region will be in proper position and proper size.
Next issue was that the handle bar keeps moving out of the container and the region starts acting crazy. You can fix it with simple css trick by applying the following css code.
Hope it helps.
handle.wavesurfer-handle-end{
transform: translateX(-100%);
}
Here's a snippet of a working solution.
$('document').ready(function() {
var wavesurfer = WaveSurfer.create({
container: '#waveform',
// waveColor: 'violet',
waveColor: '#5B88C8',
progressColor: '#264E73',
hideScrollbar: true,
cursor: false,
drag: false
});
wavesurfer.load('https://ia800301.us.archive.org/15/items/fire_and_ice_librivox/fire_and_ice_frost_apc_64kb.mp3');
wavesurfer.enableDragSelection({
drag: false,
slop: 1,
loop: false,
});
wavesurfer.on('region-created', function(region) {
console.log(region.start, region.end);
});
wavesurfer.on('ready', function(readyObj) {
wavesurfer.addRegion({
start: 0, // time in seconds
end: wavesurfer.getDuration(), // time in seconds
color: 'hsla(100, 100%, 30%, 0.1)',
loop: false,
multiple: false,
drag: false
});
})
document.querySelectorAll('wave').forEach(function(wave) {
wave.addEventListener('mousedown', function(e) {
e.preventDefault();
wavesurfer.clearRegions();
});
});
$('.toggle-width').on('click', function() {
var width = $('#wavesurferContainer').width();
width = width - 120;
$('#wavesurferContainer').width(width + 'px');
wavesurfer.drawer.updateSize();
wavesurfer.drawBuffer();
var region_list = wavesurfer.regions.list;
var region_keys = Object.keys(region_list);
region_keys.map(function(key){
var temp_region = {
start: region_list[key].start, // time in seconds
end: region_list[key].end, // time in seconds
color: region_list[key].color,
loop: region_list[key].loop,
multiple: region_list[key].multiple,
drag: region_list[key].drag
};
region_list[key].remove();
wavesurfer.addRegion(temp_region);
});
});
});

width: 9% !important;
