Access JavaScript property case-insensitively?

rated 0 times [ 117] [ 2] / answers: 1 / hits: 85689 / 12 Years ago, tue, september 18, 2012, 12:00:00

Assume I have an object:

var obj = {

  foo:bar,

  fizz:buzz

};

I need to access a property of that object dynamically like so:

var objSetter = function(prop,val){

  obj[prop] = val;

}

No problems there, except for that prop needs to be case insensitive in case the property name is passed into the function as, say, Foo instead of foo.

So how can I point to an object's property by name without regard to case? I would like to avoid iterating the entire object if possible.

Compare all the properties of obj with prop.

var objSetter = function(prop,val){

  prop = (prop + ).toLowerCase();

  for(var p in obj){

     if(obj.hasOwnProperty(p) && prop == (p+ ).toLowerCase()){

           obj[p] = val;

           break;

      }

   }

}
