[OpenLayers-Users] Adding Legends in OpenLayers

[Rahn Hanno (rahn)]

hello,
 
I made it like this.
 
First I define a function:
 
function toggleMe(a){
  var e=document.getElementById(a);
  
  if(!e)return true;
  if(e.style.display=="none"){
    e.style.display="block"
  } else {
    e.style.display="none"
  }
  return true;
}
 
Then you must create a div object where you would show the legend image. This div you can show or hide with tho onclick event. For example like this:
 
<div onclick="toggleMe('legend'); return false; " id="legend"><img src="..."></img></div>
 
You can use the function with every object and the object id.
 
Hope it will help you.
 
Greetings
Hanno

Betreff: [OpenLayers-Users] Adding Legends in OpenLayers


Hi,
 
I have legends for different WMS-layers as images, and I would like to show (and hide) the legend images like the LayerSwitcher or Minimap. Is that possible and if so how do I start implementing this?
