Is there any not loop-based approach in JavaScript or JQuery that can check presence

  • 0

Is there any not loop-based approach in JavaScript or JQuery that can check presence of some VALUE from object’s properties. I mean here if I have 

obj = { prop1:val, prop2:val2 }

is that possible with maybe one statement check is val2 presence among values of obj ?

UPDATE 1: The loop here is not the key! I can use loop if it is wrapped in some JQuery predefined function!

UPDATE 2:
Writing a hand-made function is not so elegant, I think. I would like to find some library based solution for such a common and usual problem.

    No you cannot find if a value exist in an object in one statement without looping.

    You can use native API or a library.. but they are going to internally loop thru all values.

    The toll on any other method will be same as iterating the object.. So I would write a simple for loop to do it.

    I would simply write this 4 line code in my script file and include that script file instead of including a library.. which would be the same. http://jsfiddle.net/sQW4P/2/ <– Incase if you need such a function.
