Navigator Object in javascript. How to determine all properties

How do I enumerate the properties of a javascript object?

Good day!

I want to determine all the properties of my navigator using javascript by doing this following code:

<script type="text/javascript">
    for(var property in navigator){ 
        str="navigator."+ property;   //HAVING A PROBLEM HERE...
        document.write(property+ "&nbsp;&nbsp;<em>"+ 
        str+"</em><br />");
    } 
</script>

But the concatenation of my str variable prints as it is. What i need is the actual value of the property.

eg. navigator.appCodeName should print mozilla instead of navigator.appCodeName itself.

Thank you in advance.

You want to use navigator[property] to access the values assigned to the properties.

for(var property in navigator){ 
    var str = navigator[property]
    document.write(property+ "&nbsp;&nbsp;<em>"+str+"</em><br />");
} 

You could also benefit from dropping document.write(), it's rarely the best way to modify the DOM.
