Javascript If statement, looking through an array

Question

Mind has gone blank this afternoon and can\'t for the life of me figure out the right way to do this:

if(i!=\"3\" && i!=\"4\" && i!=\"5\" &&a         


        

Answer 1

This solution is cross-browser:

var valid = true;
var cantbe = [3, 4, 5]; // Fill in all your values
for (var j in cantbe)
    if (typeof cantbe[j] === "number" && i == cantbe[j]){
        valid = false;
        break;
    }

valid will be true if i isn't a 'bad' value, false otherwise.
