I am creating an app using phonegap. I want to use local storage. I have seen some example that i cat store it using.
window.localStorage.setItem('variablename','value');
I cant find anywhere about its details. I dont know about it lifetime. If i am storing some value how much time it will stay. Means i want to know will this expire like cookies or session, after some time it will expired automatically. Or it will be stored for lifetime?

How to get the Current Date in ReactNative?
(4 answers)
Closed 2 years ago.
Is there a straight forward way to get the device time using React Native?
Preferably using an API like so:
device.getCurrentTime()
The solutions I've seen online use a bunch of libraries and I don't like that especially to do something that just seems so common that it should be apart of the API.
You should be able to use
new Date();

How can I obfuscate (protect) JavaScript? [closed]

Closed 4 years ago.
I'm installing Intercom (https://www.intercom.com) for customer engagement on my site. With the recommended installation the javascript snippet they gave would have my intercom app_id exposed in the page source.
May not be a big deal, but I was wondering if there was a better way where I could keep that hidden.
May not be a big deal
It isn't.
but I was wondering if there was a better way where I could keep that hidden
You can't.
Intercom need the browser to tell them your ID for their approach to work.
This means you must tell the browser your ID.
The browser is the property of the user and it answers to them.
It is not possible to give the browser information and keep it secret from the user who owns the browser.

how to identify remote machine uniquely in php?

We have a small web-poll system we use in a math class before semester begin on voluntary base. On one hand we dont want the students have to register or download something, because of possible lost of poll participants. On the orher hand there are some students who manipulate the poll by sending lot's of junk answers.
Is there a way to identify a user machine over http? Ideas how to create an simple identification?
Simple: it is not possible to get the users computer name with Javascript. You can get all details about the browser and network. But not more than that.
If you are looking for a simple solution just use a cookie with a far future expire marking the device as already voted. However, this is just a simple solution and does not protect you against users with minimal IT skills. You could consolidate the separation by saving a hashed value of their Browser version/os/ip with each vote and you can filter results when counting
