为Yahoo! UI Extensions Grid增加内置的可编辑器_YUI.Ext相关

原文地址 文章日期：2006/9/10

对YUI-EXT GIRD功能需求最强烈的是内置可编辑的支持。市场上大多数收费的JAVASCRIPT GIRD，我看过的那些可编辑支持，并没有给我留下太深的印象。它给你一个基本的TEXT FIELD，一些CHECKBOXS或者是Select fields,这导致了你一边单击某个字段在编辑，另一边厢插入一个FORM到这个单元格之中，不知不觉地，会出现越来越多编辑过的“脚印footprint",尤其是IE，在很多行的情况下。 所以我决定不采用这种方法，而采用类似于Windows或JavaSwing的方式，设计yui-ext Gird的编辑器。为了这一起成为可能，你的反馈必不可少，尤其是你觉得缺少了某些功能，不妨反馈给我。

可编辑GIRD的例子

这是个正在ALPHA测试中的可编辑GIRD。单击某个单元格可编辑。试试这些：输入一个错误的日期；输入大于10的price；输入早于01/01/06的日期；空白CommonName字段；测试数字字段蒙板；双击每列之间的分隔符，可自动调整每列宽度，鼠标滚轮滚动Data picker。
