Compare objects in Angular
angularjs
Solution
To compare two objects you can use:
`angular.equals(obj1, obj2)`
It does a deep comparison and does not depend on the order of the keys See AngularJS DOCS and a little Demo
var obj1 = {
key1: "value1",
key2: "value2",
key3: {a: "aa", b: "bb"}
}
var obj2 = {
key2: "value2",
key1: "value1",
key3: {a: "aa", b: "bb"}
}
angular.equals(obj1, obj2) //<--- would return true
Problem
Is it possible to do a "deep" comparison of two object in Angular? What I would like to do is compare each key/value pair. For example: Object 1 ``` { key1: "value1", key2: "value2", key3: "value3" } ``` Object 2 ``` { key1: "value1", key2: "newvalue", key3: "value3" } ``` What I need is for the comparison to fail since only one of the key/value pairs is diffent. In other words ALL of the key/value pairs must match exactly or else failure. Is this something already built into Angular. I'm sure I could write my own service if I really needed to, but I was hoping it was already built in. Similar to angular.equals.
