To check if an object is empty in JQuery we use jQuery.isEmptyObject( object ) with will return true on success , false on failure.
Ex :
|
1 2 |
jQuery.isEmptyObject({}); // true jQuery.isEmptyObject({ foo: "bar" }); // false |
To check if an object is empty or not using Javascript we use Object.getOwnPropertyNames() .The Object.getOwnPropertyNames() method returns an array of all properties (enumerable or not) found directly upon a given object.
|
1 2 3 4 5 |
var obj = {}; Object.getOwnPropertyNames(obj).length === 0; //true obj = {foo : 'bar'}; Object.getOwnPropertyNames(obj).length === 0; //false |
As a function :
|
1 2 3 |
function isEmptyObject(obj){ return (Object.getOwnPropertyNames(obj).length === 0); } |
How to use :
isEmptyObject({}); // flase
That’s it.
