Javascript: Retrieve Object Property Names
- by Jason
I'm trying to write a function that needs to know the property names of an object being passed in, like so:
var data = { "key1":"value1", "key2":"value2", etc}
^ i want the string value "key1"
How do I retrieve the string "key1" from data? I know I can set a property dynamically like data[prop]=value but i want to know what prop is from an object passed in.
If that doesn't make sense I suppose I could try to explain more. Thanks!
I eventually want to do something like:
for (var i = 0; i<data.length; i++)
{
var name = data[i].getPropertyName() <--- not a real function
// do stuff
}
