Accessing functions via multiple pages

Question

Hi,

I have a Navigation type app with multiple pages and would like to access a global function via any of the pages (or to access a function specified in the Javascript for any individual page from the Javascript for another page).

Is this possible? If so, how?

Thanks, S

Hi sarrowsmith,

I think you can use WinJS.Namespace.define to declare some global objects (with properties and functions). And you can put the declaration code in the .js file of the default.html page (which is loaded at beginning) so that other sequential page loaded (in your Navigation App) will also be able to use the declared global objects.

#WinJS.Namespace.define function

#Organizing your code with WinJS.Namespace (Windows Store apps using JavaScript and HTML)
http://msdn.microsoft.com/en-us/library/windows/apps/Hh967793.aspx

Note, for a multi-page navigation windows store javascript app, all the javascript files (referenced in the main host page and other navigation pages) will be loaded into memory in order of the pages (which reference the script files) are loaded(navigated) in the application. And after the script is loaded, they will remain in memory even if you navigate away from the certain page (the same for the CSS style).
