Hello @sanyalshubh 

You can pass data between two pages by two method:

• Use URL Parameters for small amounts of simple data. This is a quick and effective method for passing data between pages when the data is small and non-sensitive. Example: passing IDs, status, or short strings in the URL query.

window.location.href = "/sp?id=target_page&param1=value1&param2=value2";

On the receiving page, use $location.search() to retrieve the parameters:

$scope.param1 = $location.search().param1;
$scope.param2 = $location.search().param2;​

• Use Session Storage if you need to pass larger or more complex objects. Session storage allows you to store complex data (like JSON objects) temporarily within the browser session. It provides more flexibility and doesn't expose the data in the URL.

sessionStorage.setItem('complexData', JSON.stringify(yourDataObject));

On the receiving page, retrieve the data like this:

var retrievedData = JSON.parse(sessionStorage.getItem('complexData'));​

Hope this helps!
