代码改变世界

补充部分官方文档里没有的Client Library以及代码提示Schema更新(二)

  这次补充了所有的Data Access相关控件,现在似乎Atlas.js中最常用的Tag都已经写进了Schema。这次更新的Tag有:

<itemView />
<listView />
<dataSource />
<dataView />
<dataNavigator />
<xmlDataSource />
<xsltView />
<sortBehavior />
<propertyFilter />

点击这里下载,所有的下载链接均已更新。使用方式可以见我前一篇文章《为VS.NET 2005增加Atlas Scripts的代码提示功能》,那里的Schema下载也以更新。

另外,XMLDataSource也出现了DataNavigator类似的问题,在它的代码里有:
this.getDescriptor = function() {
    
var td = Sys.Data.DataSource.callBaseMethod(this, 'getDescriptor');
        
    ...
        
    
return td;
}

又是“Sys.Data.DataSource.callBaseMethod”了。哎,它们Code Review没有看出来吗?还好,似乎对结果没有什么影响……


以下是我写的Client Library,希望对大家有所帮助。
