Question

I have data that is in an array, these are the ID’s for users that have commented on said post. I want to compare this array with the id of the user, and if their id is in this array, continue with the code.

my array looks like:

({0:"1", 3:"6"}) // 1 and 6 are the ID's that I want to work with.

So I want to do something like:

var array = ({0:"1", 3:"6"});
var userID = 6;
if(in(array)==userID)
{

 ///you are in the list, so do whatever
 }

Answer 1

function inArray(needle, haystack) {
var count = 0;
for (var k in haystack) {
    if (haystack.hasOwnProperty(k)) {
       ++count;
    }
}
for (var i in haystack) {
    if(haystack[i] == needle) return true;
}
return false;
}
