The checkbox linked to a Vector layer in Openlayers 3 seems to have no effect on its visibility

Help me debug my code where I am attempting to connect a checkbox to a vector layer's 'visible' property. I can't seem to figure out what's wrong, can you spot the error?

Interestingly, this code successfully works for ol.layer.Tile, but for some reason, it's not functioning as expected with ol.layer.Vector. Strangely, the 'opacity' binding works perfectly fine.

var list = document.getElementById('some-ul-element')
....

var li = document.createElement('li');
var checkbox = document.createElement('input');
checkbox.setAttribute('type','checkbox');
checkbox.setAttribute('checked',true);
li.appendChild(checkbox);
var label = document.createElement('label');
label.appendChild(document.createTextNode(layer.get("title")));
li.appendChild(label);
var range = document.createElement('input');
range.setAttribute('type','range');
range.setAttribute('min','0');
range.setAttribute('max','1');            
range.setAttribute('step','0.01');
range.setAttribute('value','1');
li.appendChild(range);

new ol.dom.Input(range).bindTo('value',layer,'opacity');
new ol.dom.Input(checkbox).bindTo('checked',layer,'visible');

....
list.appendChild(li)

Answer №1

This method is effective for me when used on the website

By creating a new input element of type checkbox using JavaScript, and then binding its checked property to the visibility of a layer in OpenLayers, you can dynamically control the layer's visibility by changing the checkbox state.

var checkbox = document.createElement('input');
checkbox.setAttribute('type', 'checkbox');
new ol.dom.Input(checkbox).bindTo('checked', layer, 'visible');

document.body.appendChild(checkbox);

Answer №2

Have you taken a look at this stackoverflow inquiry There are also alternative solutions available instead of using the ol.dom.Input element.

Answer №3

Encountered an issue where the map I had incorporated an option that caused problems:

new ol.Map({ 
    ....
    renderer: ['dom','canvas','webgl'],
    ....
    }); 

As a result, the 'setVisible' function was completely disabled, making it impossible to use 'layer.setVisible(false)' effectively.

The problem was resolved by removing the entire "renderer" key-value pair from the ol.Map options during instantiation.
