Hello - in this part of the code that you have provided to us you have not defined any of the array.
localStorage - only saves a key and a value, it's only support string-to-string mappings, so you need to serialise and de-serialise other data structures. You can do so using JSON.stringify() and JSON.parse().
Please take a look at the link that Alena gives you.
I dont understand,
the code I used saved the key but not the value, this is the only code I had, ( as example alena gave me, which was for selectmenu) if you look at the screenshots you can see the code and result.
I am not a coder, I just want to know how to save lables to an array in localstorage.
forgive me if I sound tfo. but I am
lllya
I also have this code in add js, is it this thats needs altering, if so how?

Where did you take this part of code?
presave(...);/pre
is this function is declared?
Hello! Please use method text instead val when working with Label:
preAppery("conamelabel_136").text()/pre
instead
preAppery("conamelabel_136").val()/pre
Hi Marina,
I think I have made a mistake with app logic,
I am unsure how to effect the following
here is a screenshot to explain what I am tryng to do
I have a collection of companies, when "value changes" in the selectmenu a "where" service runs and its mapped to the collapsible. All works well.
I have added a save button
I want the user to be able to save that company to their favourite list, so if the user decides to click the favourites button this favourites list appears
I first thought an array would be the way to go, but if I save all 4 labels to an array and save it to the user data db, I would have a problem mapping each label correctly
can you suggest anything?
Hi Michael,
1) In Save button handler, add handlers to save the value of the components in the localStorage, each Label in a separate variable:
http://docs.appery.io/documentation/w...
2) And one more handler, "Add JavaScript action" with the following code:
code// get current list of favorites
var favorites = JSON.parse(localStorage.getItem( "favorites" ) "[]");
// "[]" added in case variable favorites don't exists.
// names of your variables saved in actions above
var keys = ['variable1', 'variable2', ....],
i = 0,
new_item = {};
$.each(keys, function(i, key){
new_item[key] = localStorage.getItem(key);
});
// add to array
favorites.append(new_item);
// save back to the localStorage string(!)
localStorage.setItem( "favorites", JSON.stringify(favorites) );/code
Hi,
I have done as suggested, saved all 5 variables to localstorage, and added favorites as localstorage variable
I have used the code above

error in console
after clicking on error
any ideas?
Hello! There are missing symbols. Should be the following line pre// "[]" added in case variable favorites don't exists./pre instead pre "[]" added in case variable favorites don't exists./pre
Thanks Marina,
made changes,
here is the code and console error
