Actionscript 2.0 Flash Implementation


Now that is a very easy way to drop information from your flash shopping cart into a nice looking table. However, it does come with a mighty overhead (about 40KB). We will now look at making our own output for our shopping cart.

First create an empty movie clip by pressing Ctrl-F8. Name the movie clip empty_mc, and check export for actionscript. Close this clip.

Next create another movie clip and name this one display_mc and also check export for actionscript.On this clip create 4 dynamic text boxes and give them instance names of desc, quantity, price, and total. Also create a button and name it update_btn.

We will create a new display_mc for every item in our cart. Return to the main stage and change the code to look like this:

import com.ahfx.Product;
import com.ahfx.Shopping;
var myProduct = new Product();
myProduct.setQuantity(3);
myProduct.setPrice(2.99);
myProduct.setDesc("Teddy Bear");
 
var myOtherProduct = new Product();
myOtherProduct.setQuantity(1);
myOtherProduct.setPrice(12.99);
myOtherProduct.setDesc("Cool Sunglasses");
 
var shop_cart = new Shopping();
shop_cart.addElement(myProduct);
shop_cart.addElement(myOtherProduct);
displayCart();
 
function displayCart(){
//Create main movie clip to hold shopping cart output
   empty_mc = attachMovie("empty_mc","empty_mc2",150);
//Create movie clip to hold shopping cart output headings
   temp_mc = empty_mc.attachMovie("display_mc","headings_mc",1001);
   temp_mc.total.text = "Total";
   temp_mc.desc.text = "Description";
   temp_mc.quantity.text = "Quantity";
   temp_mc.price.text = "Price";
   temp_mc.update_btn._visible = false;
   delete temp_mc;
//Loop through items in shopping cart
   for(i=0;i<shop_cart.size();i++){
      var newProd:Product = shop_cart.getElement(i);
//Attach display for each item in shopping cart
      temp_mc = empty_mc.attachMovie("display_mc","display_mc"+i,i+100);
//Shift dispay downward 16 pixels
      temp_mc._y = (i + 1) * 16;
//Place values from product in shopping cart in the text fields
      temp_mc.quantity.text=newProd.getQuantity();
      temp_mc.desc.text=newProd.getDesc();
      temp_mc.price.text=newProd.getPrice();
      temp_mc.total.text=newProd.getTotal();
//Position holder of product in shopping cart
      temp_mc.pos = i;
//button action to update quantities
      temp_mc.update_btn.onPress = function() {
         var tempProduct:Product = shop_cart.getElement(this._parent.pos);
         if (this._parent.quantity.text == "0"){
            shop_cart.removeElementAt(this._parent.pos);
         }
         else {
            tempProduct.setQuantity(this._parent.quantity.text);
         }
         displayCart();
      }
   delete newProd;
   }
//Create movie clip to hold shopping cart Grand Total output
   temp_mc = empty_mc.attachMovie("display_mc","total_mc",1000);
   temp_mc._y = (shop_cart.size() +1) * 16;
   temp_mc.total.text = shop_cart.getTotal();
   temp_mc.desc.text = "Grand Total";
   delete temp_mc;
}
