How to pass data from one portal page to another portal page?

To access data between two pages, we need to send data via URL as shown below.

Set URL as below on source page client controller :
function ($scope, $window) {
var c = this:
c.onClick = function () {
$window.location.href = "/sp?id=pass_data&number=" + INC001232;
}
}

On the server side of the target page, we can use below code to access those parameters:
var incNumber = $sp.getParameter('number');
