Analysis of extjs gridpanel's technical explanation of obtaining selected rows from operation rows

extjs gridpanel operates the row to get the column of the selected row

在Extjs 3.2.0上适合

var model = grid.getSelectionModel();  
model.selectAll();//选中所有行  
model.selectFirstRow();//选中第一行  
model.selectLastRow([flag]);//选中最后一行,flag为正的话保持当前已经选中的行数,不填则默认false  
model.selectNext();//选中下一行  
model.selectPrevious();//选中上一行  
model.selectRange(startRow,endRow, [Boolean keepExisting] );//选中范围间的行  
model.selectRow(row);//选中某一行，，，从0开始  
model.selectRows(rows);//选中指定一些行,传递数组如[1,3,5],则分别选择1,3,5行  
model.clearSelections();//清空所有选中  
model.deselectRange( startRow, endRow );//取消从startrow到endrow的记录的选择中态  
model.deselectRow(row);//取消指定行的记录grid.getSelected().id //得到选中的行的标识

<br>

得到选中的行。

书上的P62页：

 var sm=grid.getSelectionModel();

var record=sm.getSelections()[0];这个代表选择的一行,书上少了一个s。

var record=sm.getSelections()表示选中的很多行，得到的是一个数组。

精确到具体某一列的数据，， record.get("列名")。

适合Extjs 3.2

var sm=grid.getSelectionModel();

var record=sm.getSelected();

record只是一行数据。如果选择多好数据则这个不行了。

EditorGridPanel in Extjs gets the relevant information of the control in a certain cell

1. Get the control in the cell with column number colIndex and row number rowIndex The method is:

var compo= grid.getColumnModel().getCellEditor(colIndex, rowIndex);

2. Method to get the value of the control in the cell is:

var value = compo.getValue();

3. Assuming that compo is a combobox control, the method to obtain the data source of the control is:

var compoStore = compo.field .getStore();

4. Method to get the Index of the selected combobox based on 3:

var index = compoStore .find('column name', value) ;
