Ext版本4.2
覆盖方法:
Ext.override(Ext.grid.plugin.RowExpander, { setCmp: function (grid) { var me = this, rowBodyTpl, features; console.log(‘我是盖子。。‘); me.callParent(arguments); me.recordsExpanded = {}; me.rowBodyTpl = Ext.XTemplate.getTpl(me, ‘rowBodyTpl‘); rowBodyTpl = this.rowBodyTpl; features = [{ ftype: ‘rowbody‘, lockableScope: ‘normal‘, recordsExpanded: me.recordsExpanded, rowBodyHiddenCls: me.rowBodyHiddenCls, rowCollapsedCls: me.rowCollapsedCls, setupRowData: me.getRowBodyFeatureData, setup: me.setup, getRowBodyContents: function (record) { return rowBodyTpl.applyTemplate(record); // 修改 } }, { ftype: ‘rowwrap‘, lockableScope: ‘normal‘ }]; if (grid.features) { grid.features = Ext.Array.push(features, grid.features); } else { grid.features = features; } } });
同时,修改ext-all-debug.js中相应的代码如下:
setCmp: function(grid) { var me = this, rowBodyTpl, features; console.log(‘oh my gd!‘); me.callParent(arguments); me.recordsExpanded = {}; me.rowBodyTpl = Ext.XTemplate.getTpl(me, ‘rowBodyTpl‘); rowBodyTpl = this.rowBodyTpl; features = [{ ftype: ‘rowbody‘, lockableScope: ‘normal‘, recordsExpanded: me.recordsExpanded, rowBodyHiddenCls: me.rowBodyHiddenCls, rowCollapsedCls: me.rowCollapsedCls, setupRowData: me.getRowBodyFeatureData, setup: me.setup, getRowBodyContents: function(record) { return rowBodyTpl.applyTemplate(record.getData()); } },{ ftype: ‘rowwrap‘, lockableScope: ‘normal‘ }]; if (grid.features) { grid.features = Ext.Array.push(features, grid.features); } else { grid.features = features; } }
其实,就为了看看方法是否被覆盖了,在相同的位置加上了输出语句。代码执行之后,效果如下:
我是盖子。。 RowExpa...ride.js (第 6 行) oh my gd! ext-all-debug.js (第 117009 行)
居然没有被覆盖?!
