Hello, I have a problem with javaScript.
I use two pages, that are named "Startas" and "Rezultatas" accordingly.
The first page has two inputs and a button, and when I push it it should get the two inputs and add them if they are two-digit numbers, but instead it just shows those two numbers on the second page in the LABEL component. I would like to know how should i write the code to make the label element show the sum of the two inputs, instead of those inputs
codevar pirmas = Appery('Input1').val();
var antras = Appery('Input2').val();
var rezultatas;
if (((10<=pirmas) && (pirmas <= 99)) && ( (10 <= antras) && (antras <= 99)) )
{
rezultatas = (pirmas + antras);
}
else
{
rezultatas="Iveskite tik dvizenklius skaicius&quot
}

localStorage&#46;setItem('Atsakymas' , rezultatas);
Appery&#46;navigateTo('Rezultatas' , {});
/code
and the second page code:
prevar atsakymas = localStorage&#46;getItem('Atsakymas');
Appery('Output')&#46;text(atsakymas);
/pre

when i try "*" "-" and "/" operators it works just fine, could it be probelms with my keyboard/language settings?

Hello Vilis,

Your code is not correct, you are trying to concatenate strings instead of numbers, should be:

1. On button click event add Run JS:

   precode
   var pirmas = parseInt(Appery('Input1')&#46;val());
   var antras = parseInt(Appery('Input2')&#46;val());
   var rezultatas;
   if (((10<=pirmas) && (pirmas <= 99)) && ( (10 <= antras) && (antras <= 99)) )
   {
   rezultatas = (pirmas + antras);
   }
   else
   {
   rezultatas="Iveskite tik dvizenklius skaicius&quot
   }

   alert(rezultatas);

   localStorage&#46;setItem('Atsakymas' , rezultatas);
   Appery&#46;navigateTo('Rezultatas' , {});/code/pre

2. Create Storage variable Atsakymas http://devcenter.appery.io/documentat...

3. On second page on Load event this code:

   prevar atsakymas = localStorage&#46;getItem('Atsakymas');
   Appery('Output')&#46;text(atsakymas);/pre

   In case you have problems with JavaScript, first try to debug it.
   Actually, custom code is outside the scope of support.
