Arrays must have zero based integer indexes in JavaScript. So:
var valueToPush = new Array(); valueToPush[0] = productID; valueToPush[1] = itemColorTitle; valueToPush[2] = itemColorPath; cookie_value_add.push(valueToPush);
Or maybe you want to use objects (which are associative arrays):
var valueToPush = { }; // or "var valueToPush = new Object();" which is the same valueToPush["productID"] = productID; valueToPush["itemColorTitle"] = itemColorTitle; valueToPush["itemColorPath"] = itemColorPath; cookie_value_add.push(valueToPush);
which is equivalent to:
var valueToPush = { }; valueToPush.productID = productID; valueToPush.itemColorTitle = itemColorTitle; valueToPush.itemColorPath = itemColorPath; cookie_value_add.push(valueToPush);
It’s a really fundamental and crucial difference between JavaScript arrays and JavaScript objects (which are associative arrays) that every JavaScript developer must understand.
