jquery easyui DataGrid Get checked Select row (Shang) data

GetSelected: Gets the first selected row data, or returns null if no row is selected, otherwise returns the record.
Getselections: Gets all the selected row data and returns the array data for the element record.

GetChecked: Gets the data from the CheckBox selection row, returning the array data for the element record.

GetSelected and Getselections are selected rows, and getchecked is the selection row.

The selected line means that we click to a row, generally this time the default style will make the background color of the row yellow, it proves that we have selected the row.

and choosing the line means that we put a CheckBox button in the row, and I tick this button, so I can also call the selection line Shang more appropriate.

var selrows = $ (' #Selproduct-table-list '). DataGrid (' getchecked ');
