我搜索了ExtJS相关的问题,没有找到任何参考资料,但是如果我错过了它,很抱歉提前提出重复的问题。
我想问一些关于如何使ExtJS 4网格:单元格编辑:自动编辑功能的帮助-我的意思是,当我按下一个键时,我想进入单元格编辑模式(例如,在突出显示的单元格中按下“123”,文本(如果有)将被替换为“123”)。此时可通过按ENTER键或鼠标单击进入单元格编辑模式。
作为基础,我使用了Sencha提供的示例:http://dev.sencha.com/deploy/ext-4.0.2a/examples/grid/cell-editing.html
任何提示,指点都会很感谢。
提前感谢!:)
实际上,我确实部分解决了我的问题。找到了一种方法,使单元格可编辑的按键,把selectOnFocus配置参数的文本选择在单元格中,现在我需要插入第一个字符(启动编辑模式)在单元格中。
它可能不是最好的解决方案,但它对我来说是有效的:)到目前为止,这是完整的代码。

storeId:'simpsonsStore',

很抱歉让你久等了,但我只能说我在度假,坐在海边喝着莫吉托斯…思考生活,土豆,以及我对即将到来的项目网格的真正需求。我对以下几点得出了结论:
总体而言,我覆盖了Ext.core.Element (修复Windows7上使用IE9和Firefox6.0.2出现的奇怪错误。更多详细信息,请参阅代码中的注释),Ext.grid.plugin.Editing (通过按数字键进入编辑模式)和Ext.Editor (设置新值)。
TODO:在编辑模式下,按Enter键不仅可以完成编辑,还可以向下移动一个单元格(类似于Excel)
PS。为我的英文…道歉不是我的母语,但希望它或多或少是可以理解的。另外,也感谢您的意见和建议!;)
/**
* Fix for bug with cursor position in editor grid textfield
*
* Bug description: after loading an editor grid which contains a textfield, the cursor / caret is positioned at the
* beginning of text field the first time the editor is activated. Subsequent activations position the caret at the end
* of the text field.
* In my case this behavior is not observed in Opera 11.51 (Windows 7) and IE8, Firefox 6.0.2 (Windows XP), but observed in IE9 and Firefox 6.0.2 (Windows 7)
*
* Current fix helps with IE9 problem, but Firefox 6.0.2 (Windows 7) still putting the cursor / caret at the beginning of text field.
*
* Forum post for ExtJS v3 about same problem and where the fix was found: http://www.sencha.com/forum/showthread.php?88046-OPEN-3.1-Caret-Cursor-Position-in-Editor-Grid-Textfield
