Global Counter?

    Edited last year by Jack T


    Does anyone know if it is possible to have a global counter or a global variable? I would like the actions I do on page 1 to affect my possible actions in page 2 or 3.


    Edit: Found that the counters in the overlay also does not keep their value over pages.

    At the moment, you have to use Javascript for those kind of things.

  3. Sorry but I tried with all different ways to define a global variable and seems impossible. could you give a specific example in pubcoder?

    To share data among different pages you should use LocalStorage, be sure to check support in the reader app you will be using.

  5. Thank you a lot @Angelo S for your reply. I have already used localstorage and I have the following problem. Eg. I define in project javascript a global counter variable:
    Now if I want to change its (global) value by eg. clicking a button on a page it seems impossible. I use run Javascript there eg. on tap of a button, event is run javascript and I try to trigger the apearence of a text.
    if (localStorage.counter==2){$("#obj111").show()}
    This seems not to work because for the program localStorage.counter is still 1. (so if in the if I set 1 instead of 2 the object does show)

    Could you explain how I can fix this? I have tried also with page javascript and it seems it is the same.
    I could sum up the problem as follows. if localStorage variable is written on project javascript then every page "sees" it but if I try to adapt its value locally on a page it is impossible.

    Thank you in advance

  6. Ok I managed to do it. but it is very difficult to understand that a variable in local storage defined in the project will not be updated. Maybe a tutorial on how to use html/javascript in pubcoder would be very helpful.

    You're not using localstorage the right way. Please check this documentation for further help:

    As for documentation for using javascript in PubCoder, here's the right reference:

    Of course this includes only things specific to PubCoder, it's not intended as a comprehensive JavaScript/HTML/CSS guide...
