Dynamic Regular Expression ?

[James Davidson]

Is there any way to create a dynamic regular expression? For example, I have the following code:

  
function changeIcon(object)
{
var ACTIVE   =   "Active";
var INACTIVE = "InActive";
 
var iconSrc = object.src;
 
if (iconSrc.indexOf(INACTIVE) < 1)
{
iconSrc = object.src.replace(/Active/g, INACTIVE);
}
else
{
iconSrc = object.src.replace(/InActive/g, ACTIVE);
}
 

object.src = iconSrc;
}

I would like to use the constant values defined to create the regular expression. Something like: var regexp = / + ACTIVE + /g;

However, this does not work. Any suggestions?

var regEx = new RegExp(variable,"gi");
