You want to send variables to a server-side script and handle the results of the server-side processing.
You should use the
sendAndLoad( ) method when
you want to send variables to a server-side script and have the
results returned to Flash. An example of such a scenario is a Flash
storefront for a product catalog that is stored in a database.
Typically, items are categorized. When a user selects a category, the
Flash movie might send the selected category ID to a server-side
script and expect the script to return all the items in the category.
sendAndLoad( ) method sends variables to a
server-side script in the same way that the
) method does. Any enumerable properties of the
LoadVars object are automatically sent to the
script at the specified URL. The difference between
sendAndLoad( ) is that with the
latter you must also provide a reference to a
LoadVars object that handles the loading of the
results. You can use the same
LoadVars object to
load the returned data as you used to send the variables. However, it
is a best practice to specify a different object for loading the
data. Using two
LoadVars objects avoids conflicts with variable names. Otherwise, if the sending object has a property with the same name as one of the loaded variables, the loaded variable overwrites the sending object’s property. Here is an example using two separate ...
