阅读更多

Ext4.0 自带的Ext.ux.RowEditing还不够完善,随手写个ux来用下,

 

v1.4 2011-09-12 变更内容:

1.重构,修复不少bug以及合并/新增一些配置项(具体看附件中的文档)

2.支持jsduck生成文档 (https://github.com/senchalabs/jsduck)

 

 

v1.0 2011.04.27 变更内容:
1.增加canceledit事件
2.增加startAdd方法,方便crud表格的添加操作
3.添加点击取消按钮后,自动重置或删除记录的功能

v1.1 2011.05.03 变更内容:
1.startAdd方法增加position参数,修复autoSync设值的bug
2.配置参数removePhantomsOnCancel改名为autoRecoverOnCancel
3.startEdit前先调用cancelEdit函数,以便正确的恢复现场

v1.2 2011.05.04 变更内容:
1.包名改为Ext.ux.grid.plugin
2.添加配置参数hideTooltipOnAdd
3.判断是否删除新增记录的逻辑优化
4.代码风格等方面的改进

 

v1.3 2011.05.22 变更内容: 

1. 设置clicksToEdit为0,可取消双击/单击事件触发编辑

2. 提供field默认配置,只需给column添加一个fieldType 

 

           {
               text: 'Enable',
               dataIndex: 'enable',
               width: 80,
               renderer: function(v){return v?'Enable':'Disable'},
               fieldType: 'checkboxfield',
               field: {
                   boxLabel: 'Enable'
               }
           }

 

代码如下:
