Showing child grids in an IFRAME without custom grid

Here is some code where you can just insert some fetch xml in JavaScript and display the data in the standard grid. just replace the IFRAME_<name> and adjust the CHANGE HERE section with some custom fetch xml and the entity type name.

//Load view data

function GetAdvFindView(entityname)

{

var xml = "" +
