Replace dodgy chars

[whisher]

Hi.
I've got this php code

protected function sanatizeInputValue($value)
  {
    $dodgychars = "#[|\!\"'\$£%&\/()=?^<>\*\+\-]#";
    $filterValue = preg_replace($dodgychars,"-",$value); 
    return substr($filterValue,0,255);
  }

How can I tanslate this in js code
I tried but with very poor result
can you show me the way, please ?

Bye

var toReplace = {
    '|': '-',
    '!': '-',
    '"': '-',
    '£': '-',
    '%': '-',
    '&': '-',
    '/': '-',
    '(': '-',
    ')': '-',
    '=': '-',
    '?': '-',
    '^': '-',
    '*': '-',
    '°': '-',
    '*': '-',
    '§': '-',
    '@': '-',
    '#': '-',
    '_': '-',
    ';': '-',
    ':': '-',
    '!': '-',
    '.': '-',
    '<': '-',
    '<': '-',
};
var string = '<This ?^*ù is a test'.replace(/./g, function (match) {
    return toReplace[match] || match;
});
alert(string);

I'm lucky I found it in my repository
I don't remember the really author

function sanatizeInputValue(value) {
    var dodgyChars = /[|!"'$£%&\/()=?^<>*+-]/g;
    return value.replace(dodgyChars, '-').substring(0, 255);
}

    return value.replace(dodgyChars, '-').substring(0, 255);
}

Thanks for the help
It was my first attempt but
it didn't work may be for the lack
of the modifier

Bye
