Hide data grid in Custom Script

Standard HR.Net Java Script tools does not allow to hide data grids, but this is sometimes required.
Here is a JS function to hide data grids.

function hideDataGrid(gridName){



	var grid = document.getElementById(name); 

	var openButton = document.getElementById(name+"Grid_ImgOpen");

	var insertButton = document.getElementById(name+"Grid_ImgInsert");

	var deleteButton = document.getElementById(name+"Grid_ImgDelete");

  

  if (grid != null)  grid.style.display = 'none';  

	if (openButton != null) openButton.style.display = 'none';

  if (insertButton != null) insertButton.style.display = 'none';

  if (deleteButton != null) deleteButton.style.display = 'none';

  

}
