Access non-numeric Object properties by index?

Question

If I have an array like this:

var arr = [\'one\',\'two\',\'three\'];

I can access different parts by doing this:

console.lo         


        

Answer 1

by jquery you can do this:

var arr = $.map(obj,function(value, key) {
    return value;
});
alert(obj[0]);

Answer 2

I went ahead and made a function for you:

 Object.prototype.getValueByIndex = function (index) {
     /*
         Object.getOwnPropertyNames() takes in a parameter of the object, 
         and returns an array of all the properties.
         In this case it would return: ["something","evenmore"].
         So, this[Object.getOwnPropertyNames(this)[index]]; is really just the same thing as:
         this[propertyName]
    */
    return this[Object.getOwnPropertyNames(this)[index]];
};

let obj = {
    'something' : 'awesome',
    'evenmore'  : 'crazy'
};

console.log(obj.getValueByIndex(0)); // Expected output: "awesome"

Answer 3

you can create an array that filled with your object fields and use an index on the array and access object properties via that

propertiesName:['pr1','pr2','pr3']

this.myObject[this.propertiesName[0]]
