text = text.replace(/h/g, "*").replace(/l/g, "-");

In answer to you comment below

* is a special character in a Reqular Expression pattern, you need to escape it using a backslash (\) character. So it would be

replace(/\*/g, 'o')

See this quick guide on JavaScript Regular Expressions

we can't do it in a single replace call...?

You want to match two different strings and replace them with two different strings. I don't see how you could do that in one replace call

var string = "hello hw r u";
string = string.replace(/(h)|(l)/g,function(str,p1,p2) {
        if(p1) return '*';
        if(p2) return '-';
    });
alert(string);
