Ext4.1如何禁止对某些单元格进行编辑

　　Ext4.1如何禁止对某列进行编辑，或者对一些特殊的单元格不允许进行编辑

　　可以通过beforeedit事件对单元格进行判断，不符合编辑的单元格单击编辑时return false阻止生成输入控件。

　　Ext4.1 Ext.grid.PanelView事件的介绍如下

beforeedit( editor, e, eOpts )：Forwarded event from Ext.grid.plugin.Editing.

Fires before editing is triggered. Return false from event handler to stop the editing.

Available since: Ext 4.1.0

Parameters

• editor : Ext.grid.plugin.Editing
   
• e : Object

  An edit event with the following properties:

  • grid - The grid
  • record - The record being edited
  • field - The field name being edited
  • value - The value for the field being edited.
  • row - The grid table row
  • column - The grid Column defining the column that is being edited.
  • rowIdx - The row index that is being edited
  • colIdx - The column index that is being edited
  • cancel - Set this to true to cancel the edit or return false from your handler.
  • originalValue - Alias for value (only when using CellEditing).
• eOpts : Object

  The options object passed to Ext.util.Observable.addListener.

    var cellEditing = Ext.create('Ext.grid.plugin.CellEditing', {
        clicksToEdit: 1
    });
    // create the grid and specify what field you want
    // to use for the editor at each header.
    var grid = Ext.create('Ext.grid.Panel', {
        //....其他配置
        listeners: { beforeedit: function (editor, e, eOpts) {
            if (e.field == 'common') return false;
            return true;
        }
        },
        plugins: [cellEditing]
    });
