Here’s a peice of code extracted from a shopping cart class i am working on:
private function getMissingProperties(obj:Object):String
{
var errorString:String = "";
var nProps:Number = this.cartItemPropertyNames.length;
for (var i:Number = 0; i < nProps; i++)
{
var propName:String = this.cartItemPropertyNames*;
var prop:String = obj[propName];
if (prop != "amount" && prop == undefined);
{
errorString += propName + "(" + i + ") = " + prop + "
";
}
}
return errorString;
}
Now the question: Why does this function keep returning this:
id(0) = testIdForSmurfer
name(1) = Smurfer
amount(2) = undefined
It certainly looks like the line if (prop != “amount” && prop == undefined) shouldn’t kick in as the values in the return string definately indicate that the properties to be checked for existence are indeed existing and that the “amount” property is beeing counted in even though it should not.
Any ideas?
