localStorage to integer

[Andy Jacobs]

Ok, I've scoured the net, tried every combination I can think of and now I'm going to go mad!

I've got a localStorage variable called SR which is input from a form.

I want to turn this into an integer.

When I use the console to examine the DOM, I can see:

""12345""

So it's definitely there but being stored as a string.

I've then got:

var SR = parseInt(localStorage.SR);
alert (SR);

The alert box just comes up with NaN

If anyone has any ideas it would save my sanity

Regards
Andy

Hello,

To get value stored in localStorage use this code
prelocalStorage.getItem('name');/pre

where name - name of localStorage variable

Hi Alena

Thanks for the reply.

But that gives me a string.

I need to do some maths on several localStorage variables.

Andy, perhaps this might work:

var t1 = localStorage.getItem('name');
var t2 = Number(t1);

Hi Robert

Thanks for that. I'm sure I've tried something similar but this is what I've added now:

var t1 = localStorage.getItem('SR');
var t2 = Number(t1);
localStorage.setItem('REBATE', t2 * 0.86 /100);

This comes up with NaN as well.

Hello,

Could you check, what values do variables t1 and t2 have?
E.g.:

prealert(t1);
alert(t2);/pre

Hi Sergiy

Thanks for the reply. I think I may have a solution. I have this working using your API but I wanted to avoid using this as I assumed that this would rely on an internet connection. This project specifies that the app must work offline. One of your colleagues has told me that I can use the API and that some magic will happen when I package it as an APK or IPA file.

If this is definitely the case then this is perfect!

Best regards
Andy

If your app doesn't use appery.io DB, you can just export it and use without internet connection. If it uses local DB, please follow this tutorial: https://devcenter.appery.io/tutorials...
