I have a unique requirement to traverse through an associative array like a circular list. The associative array is structured as follows:
array = {item1:array(...), item2:array(...), ...}
When I reach the end of one array, I want it to seamlessly transition to the next element and continue exploring the arrays in a circular manner. The same applies when reaching the last element; it should loop back to the initial element.
To achieve this functionality, I initialize my array using the following approach:
// Construct the associative array
Prot.prototype.additem = function(itemName, itemArray)
{
this.array[itemName] = itemArray; // where itemArray is an array
}
// Set the starting currentItem of the associative array for exploration (Can start at any key)
Prot.prototype.init = function(itemName)
{
this.currentItem = this.array[itemName];
this.currentItemArray = 0;
}
Prot.prototype.next = function()
{
// Here, I navigate through the first array associated with the first key of my associative array
var index = this.currentItem.indexOf(this.currentItemArray);
index = index + 1;
this.currentItemArray = this.currentItem[index];
if (index == (this.currentItemArray.length - 1))
{
// Upon reaching the end of the array corresponding to the first key, move on to the second key
return false;
}
else {
return true;
}
}
// A set interval is added at the end to automate the process without requiring a loop
