Chapter 12: Using external files
Firstly a new LoadVars object is created and called ‘lv’. The callback that will be used whenever
the object has loaded some variables is set to the function called ‘loaded’. A LoadVars object passes
a single parameter into the onLoad function that indicates whether the load was successful or not.
We can use this parameter to adjust the behaviour of the movie. We do not have to call this
parameter ‘success’; it is simply a Boolean variable (true or false) and can have whatever name we
choose.
If the load is successful then the variables are not at the root of the movie, instead they are all
inside the LoadVars object. For example if the file ‘myvariables.txt’ contained:
Apple=1&Pear=2&Orange=3
then the object lv would contain:
lv.Apples = 1
lv.Pear = 2
lv.Orange = 3
Chapters 14, 21 and 22 give more information about communicating with databases using Flash and
ASP pages.
Using JavaScript on the current page
Flash can communicate with the current page using any JavaScript function that is placed on the
page using the ActionScript function ‘fscommand’. This function takes two parameters: the first is
a string that can be used as a command name, the second is used for arguments. Because Internet
Explorer uses VBScript as the default scripting language you need to put a VBScript version on
the page and a JavaScript version. In example ‘Examples\Chapter12\fscommand.html’ we use a
simple Flash movie ‘fscommand.swf ’ which is created with the project file ‘fscommand.fla’.
The ‘Set’ button calls a function ‘onSet’ which contains the following code:
function onSet(){
fscommand("setSpan", str);
}
