I have an array of objects like this:

var my_array = [
    {
        value1: 5,
        value2: 3,
        value3: 'test'
    },
    {
        value1: 1,
        value2: 1,
        value3: 'hello'
    }
];

When I grab a new object, it looks like this:

var my_object = {
    value1 = 1,
    value2 = 1,
    value3 = 'hello'
};

How can I loop through my_array to see if it already contains the value of my_object. Also, please don't rely on the property names; references are removed immediately after being added to the array.

Do you mean by reference, or by value? If by value, how deep? – Frédéric Hamidi Jan 25 '12 at 20:16
By value sorry, I'll update the post. – Nahydrin Jan 25 '12 at 20:16
Your object literal is wrong! replace `=` with `:` and enclose the key parts with `"` – Shiplu Mokaddim Jan 25 '12 at 20:21
Your my_array declaration isn't valid. Objects are specified with `prop: value`, not `prop = value`. – jfriend00 Jan 25 '12 at 20:22
