You can get the row index and column index by utilising the static methods getRowIndex() and getColumnIndex() which are located in the GridPane class.
您可以使用位于 GridPane 类中的静态方法 getRowIndex() 和 getColumnIndex() 来获取行索引和列索引。
System.out.println("Row: "+ GridPane.getRowIndex(text1));
System.out.println("Column: "+ GridPane.getColumnIndex(text1));
See for reference: http://docs.oracle.com/javafx/2/api/javafx/scene/layout/GridPane.html#getRowIndex(javafx.scene.Node)
