How can I hide an element with A-Frame?

问题:

What is the best way to hide an element using A-Frame?

Do I need to remove the element from the DOM?

var el = document.querySelector("#yourElementId");

el.setAttribute("visible",false);

The easiest way to hide an element is the visible attribute:

myElement.setAttribute("visible", false)

You can also specify it on the a-frame tag itself e.g.:

<a-image id="hand-overview-chart"
  src="#handOverviewImg" position="3 3 0"
  width="4" height="4" visible="false">
</a-image>

Of course you'll still need javascript to trap on some event like "mouseenter" to toggle it visible:

document.querySelector('#myElParentId').addEventListener('mouseenter',myEventHandler); 

myEventHandler: function (evt) {
  let myEl = document.querySelector("#hand-overview-chart");
  myEl.setAttribute("visible","true");
}
