No need escape the character:

It is working here

alert("<%=%>")

Check console for errors, which blocking it to alert.

Try this:

alert("\<\%=\%\>");

The '\\' characters escape the following character to stop them being interpreted as jsp delimiters.

<script language="javascript">  
function one()  
{  
    alert("var: "+<%= var %> );  
}
</script>
