Object Looping in javascript

Question

This may be simple question, but i tried a lot and i can't find the solution. My problem is i want to loop through an object and get the properties of the object.

My object look like this:

{ value1: '0.92',
  value2: '3728104',
  value3: '43',
  value4: '0.66',      
}

I want to get value1, value2, value3, value4

My code:

 console.log("bbbbb=" +util.inspect(results));
        for (var prop in results) {
            console.log("Inside for");----------------------> This is printing once.
            keys.push(prop);
            console.log("After push");--------------------->This is not printed..
        }           
        console.log("keys=" +keys)

But its not looping ,, Help me to solve this.. Thanks in advance..

it should work fine... your code outputs ["value1", "value2", "value3", "value4"] for console.log(keys); Isnt that what you want..? — Sudhir Bastakoti

You can use Object.keys function like this

console.log(Object.keys(results));
# [ 'value1', 'value2', 'value3', 'value4' ]

Actually, your code has no problems at all

var results = {
    value1: '0.92',
    value2: '3728104',
    value3: '43',
    value4: '0.66',
};

var keys = [];
for (var prop in results) {
    keys.push(prop);
}

console.log(keys);
# [ 'value1', 'value2', 'value3', 'value4' ]

If i put some console.log() b4 push statement its printing,but nothing below that..

@Subburaj Please show the actual code you used and show us the output of console.log(keys), after the loop.

@Subburaj Please try the code I have shown in the answer, as it is.

Ya that works...I am still confused..i have declared keys array globally.. thats the problem..

@Subburaj Most likely. Without seeing the actual code and the actual error, that is out best bet.
