Need regular expression for making text between * bold

I'm trying to bold the text between *, like *bold* I'm trying regular expressions in JavaScript but I don't know why its not working. 

var bold = /\*(.*?)\*/gim;
var replacedText = replacedText.replace(bold, function($0,$1){
    return $1?$0:'<b>' + $0 + '</b>';
});

Thank you guys here is final Answer

var bold = /\*(.*?)\*/gim;
var replacedText = replacedText.replace(bold, function($0,$1){
    return $1 ? ('<b>' + $1 + '</b>') : $0;
});

Something like:

function makeBold(id) {

  var re = /(\*)([^*]*)(\*)/g;

  var el = document.getElementById(id);
  el.innerHTML = el.innerHTML.replace(re, '<b>$2</b>');
}

should get you started.

The regex is OK, but your logic is not:

var replacedText = replacedText.replace(bold, function($0,$1){
    return $1 ? ('<b>' + $1 + '</b>') : $0;
});

The condition was inverted, and in any case you should be using $1 when replacing instead of $0 (the latter includes the asterisks).
