I would like to display a small tooltip that will embed chinese characters that users select on a web page. Actually, I just want to be able to enlarge the font. I have seen this kind of functionality on another website (ramou.net) but I don't think the way he has coded it is the most simple (and it doesn't seem to be very generic).
Any hints are welcome !
Thank you !
Found the solution :
<!DOCTYPE html>
<html>
<head>
<script>
function Mid(String, i, lon)
{ return String.substr(i-1, lon); }
function Len(String)
{ return String.length; }
function AscW(String)
{ return String.charCodeAt(0); }
function EstMotChinois(sUni) {
var kUniMin = 19968
var kUniMax = 40869
var i, iLon, iUni;
var bDes = false;
iLon = sUni.length;
if(iLon == 0) { return bDes; }
for(i=1; i<=iLon; i++) {
iUni = AscW(Mid(sUni, i, 1));
if(iUni < kUniMin || iUni > kUniMax) {
return bDes; }
}
bDes = true;
return bDes;
}
function displayChar()
{
sUnicode = document.getSelection().toString();
if(EstMotChinois(sUnicode)){
document.getElementById('toolTip').style.display = 'block';
document.getElementById('toolTip').textContent = document.getSelection();
}
}
</script>
</head>
<body >
<div style="background-color: rgb(12, 135, 140); border: 1px solid rgb(102, 0, 0); position: absolute; top: 30px; left: 30px; display: none; font-size: 30px;" id="toolTip" onclick="document.getElementById('toolTip').style.display = 'none';"></div>
<p onmouseup="displayChar()">
