javscript: specific chars decode problem

[Dmitry]

Code sample:

<script>
alert("°")
document.write("°")
</script>

Question: How can I force alert() to produce the same
result as document.write() ?

unescape() does not work.

Thank you, Dmitry

You need to extract the numeric value from the html code, then convert it to
an integer whose value you convert to a single-character string.

alert( String.fromCharCode( parseInt( "°".replace( /\D/g, "" ) ) )

If you intend do this repeatedly, it's best to write a function:

function htmlToChar(charCode)
{
return String.fromCharCode( parseInt( charCode.replace( /\D/g, "" ) ) );
}

alert( htmlToChar("°") );

....unless someone knows another way that eludes me...

Thank you, I've thought about something simular,
but the best thing is to have a fn for all cases,
ie the fn, which accept a string, possibly containing
html char codes together with plain chars and returns
decoded string.

I'am not so good in regular expressions programming,
so any help in writing this fn will be greately
appreciated.

Thanks, Dmitry
