Read Selected Sub grid Records MS CRM 2013 Using JavaScript !!!

Sometimes we have requirements to play with selected sub-grid records using client side scripting.

Here is same code to read selected sub-grids records :

function ReadSelectedSubGridRecords() {

        if (document.getElementById("SubGridName")) {

        var grid = document.getElementById("SubGridName").control;

        for (var row = 0; row < grid.get_selectedRecords().length; row++)

            alert(grid.get_selectedRecords()[row].Name);

    }

}
