I use ajax in my application it works fine .Currently i load all the javascript function which is used at once.This reduces the initial downloading time .For e.g. i have 20 javascript functions .I need that initially i download say 5 javascript functions and let user start doing what he wants which is accomplished by this 5 function 95% of the time .WWhat i want to know is that how can i download other javascript function in background which is not needed initially.Let say i javascript function in 4 javascript files Initially i download only 2 files when downloading of files this files completed then only download of other files continue.
Thanks
