Connecting to the data fileNow that the movie is set up, it's time to talk to the data file! Create a third layer called Actions and enter the following on the first frame: //load the text file Replace the filename text.asp with the name of your file. When you reference the variables from the file, you'll need to refer to them using: loading.variablename You need to make sure that the data file has been loaded before you can
start working with the variables. Add the following code on frame two of the
actions layer to test whether the file is loaded.
loading.onLoad = function() {
When the End variable has a value of 1, the whole file has been loaded. If the file is loaded, we move to the end frame with the chart. Place a stop action on frame three. Note: If you want to check that your data has loaded
successfully into Flash, use trace to display a variable as shown below. Replace
ChartValues with the name of one of your data file variables and add to the
third frame. The value of the variable should display. If you see the word
undefined, you know that something has gone wrong and that the data hasn't
loaded!
trace(loading.ChartValues);
