One Checkbox on at a time

CraigLinn · ‎09-24-2014

I need assistance in working with my code so that only ONE check-box can be turned on at a time while the other will turn off if already active. Thanks,

Use a RadioButton instead of a CheckBox

Thanks, I also found you need to remove the " + layer.layer.id" from " name: "radio" + layer.layer.id, "

The buttons work in the above case given both service layer id are 0.

//add radio buttons

array.forEach(legendLayers, function (layer) {

var layerName = layer.title;

var checkBox = new RadioButton({

value: layer.layer.id,

checked: layer.layer.visible,

});
