jQuery inArray not picking up value - clearly in array

Question

console.log(response.key);
console.log(answersNeedToBeBoolean);
console.log($.inArray(response.key, answersNeedToBeBoolean));

Output in console:

177
[8, 177, 179, 181]
-1

These seems pretty cut and dry to me. Clearly 177 is in the array. How on earth could it not find it?

can you try console.log(jQuery.isArray(answersNeedToBeBoolean)) — Arun P Johny

It works if the values are as you've stated. There's something more to it than that. — Amit Joki

One reason could be answersNeedToBeBoolean is an array of int values where as response.key is a string so try console.log($.inArray(+response.key, answersNeedToBeBoolean)); — Arun P Johny

See, if response.key is a string '177' output would be -1

177
[8, 177, 179, 181]
-1

If its an integer 177 output would be 1.

Use JSON.parse() or parseInt(), as you have an integer array.

$.inArray(JSON.parse(response.key), answersNeedToBeBoolean)
