Question

When using AngularJS services to pass data, the data may be lost when the page is refreshed

I'm facing an issue with transferring data from controller A to controller B using a Factory (or a Service) when the user refreshes the browser. I am able to successfully set the data in controller A and retrieve it in controller B, but upon refreshing the page while on the controller B view, the data is lost and returns as "undefined". I believe using $localStorage could help solve this problem, any suggestions? What could be causing this issue?

The service factory I have implemented is quite straightforward, with an object defined as:

var obj = {};

and two methods:

    return{
getObj: function(){return obj;},
setObj: function(data){ obj = data;}
    };

Controller A utilizes the setObj method, while controller B makes use of getObj. Everything functions properly the first time around, but encountering a page refresh while on the controller B view results in loss of data.

Indeed, your information will unfortunately be erased when the page is refreshed, but this is a common occurrence. When you reload the page, the service and controllers linked to your current page are reloaded as well, causing the data to reset. In your situation, the object

var obj = {};

is initialized anew.

To avoid losing your data, you can save it in localStorage or a cookie for persistent storage. My recommendation would be to utilize localStorage due to its larger size capacity and efficiency compared to cookies. With cookies, the data will be sent with each Ajax request, which is not ideal.
