I got it ... (create an object so it's passed with the address) how asking is already solving a bit! Here we are (code tested and ok) :
Code:
<html>
<head>
</head>
<body>
<script src="../flovinax.js" type="text/javascript"></script>
<script type="text/javascript">
function toggleEditor(edtX, edtN) {
if(edtX.edt===null) {
edtX.edt = new flovinaxa({fullPanel : true}).panelInstance(edtN);
} else {
edtX.edt.removeInstance(edtN);
edtX.edt= null;
}
}
</script>
<h4>Textarea Example</h4>
<div>
<textarea style="width: 800px; height: 200px;" id="boxA"></textarea>
<br />
<script type="text/javascript">
edtA={edt:null}; // THE OBJECT edtA
</script>
<button onClick="toggleEditor(edtA,'boxA');">+</button>
</div>
<div style="clear: both;"></div>
<h4>Textarea Example</h4>
<div>
<textarea style="width: 800px; height: 200px;" id="boxB"></textarea>
<br />
<script type="text/javascript">
edtB={edt:null}; // THE OBJECT edtB
</script>
<button onClick="toggleEditor(edtB,'boxB');">+</button>
</div>
<div style="clear: both;"></div>
</div>
</body>
</html>
