Deleting Layers

Question: How do I delete a layer from JavaScript?

Answer: Here's the example that you've already seen in the Creating Layers section:

This example was created using the following code:

<form>
<input type=button value="Create layer"
onClick="makeLayer('LYR1',200,10,100,100,'red',1,1)">
<input type=button value="Delete layer"
onClick="deleteLayer('LYR1')">
</form>
To delete a layer, given the layer's ID, this code calls the function deleteLayer(id). Here's the JavaScript source code of this function:
function deleteLayer(id) {
 if (document.layers && document.layers[id]) {
  document.layers[id].visibility='hide'
  delete document.layers[id]
 }
 if (document.all && document.all[id]) {
  document.all[id].innerHTML=''
  document.all[id].outerHTML=''
 }
}
