我有一个从 Web 服务加载数据的 AdvancedDataGrid。它只加载顶层的东西，然后当你单击箭头时它会获取该数据。
我想要做的就是找出某些文本是否在其中一个单元格中。我最初是这样做的：
public static function assertTextInAdg(params:Object):Boolean{
// Gets the ADG
trace('youre in the assertTextInAdg function');
var grid:* = FPLocator.lookupDisplayObject(params);
trace('var grid:* = FPLocator.lookupDisplayObject(params): ' + grid);
// Convert ADG to automation delegate to get an array of column names
var newGrid:* = new AdvancedDataGridAutomationImpl(grid);
trace('var newGrid:* = new AdvancedDataGridAutomationImpl(grid): ' + newGrid);
var datas:AdvancedDataGridTabularData = newGrid.automationTabularData as AdvancedDataGridTabularData;
trace('var datas:AdvancedDataGridTabularData = newGrid.automationTabularData as AdvancedDataGridTabularData: ' + datas);
var columnId:Array = datas.columnNames as Array;
trace('var columnId:Array = datas.columnNames as Array: ' + columnId);
// Convert ADG data to an array of rows
var gridView:HierarchicalCollectionView = grid.dataProvider as HierarchicalCollectionView;
trace('var gridView:HierarchicalCollectionView = grid.dataProvider as HierarchicalCollectionView: ' + gridView);
var gridData:HierarchicalData = gridView.source as HierarchicalData;
trace('var gridData:HierarchicalData = gridView.source as HierarchicalData: ' + gridData);
var gridArrayColl:ArrayCollection = gridData.source as ArrayCollection;
trace('var gridArrayColl:ArrayCollection = gridData.source as ArrayCollection: ' + gridArrayColl);
var gridArray:Array = gridArrayColl.source as Array;
trace('var gridArray:Array = gridArrayColl.source as Array: ' + gridArray);
var validator:String = params.validator;
trace('var gridArray:Array = gridArrayColl.source as Array: ' + validator);
for (var i:int = 0; i < gridArray.length; i++) {
for (var j:int = 0; j < columnId.length; j++) {
if (gridArray[i][columnId[j]] == validator) { return true; }
}
}
throw new Error("Validator not found in ADG.");
}
如果数据是从代码中提供的，则此方法有效，但是现在我正在尝试使用从服务器提供的数据进行相同的操作，并且跟踪如下所示：
youre in the assertTextInAdg function
var grid:* = FPLocator.lookupDisplayObject(params): companyDashboard.dashboardCanvas.dashboardGrid
var newGrid:* = new AdvancedDataGridAutomationImpl(grid): [object AdvancedDataGridAutomationImpl]
var datas:AdvancedDataGridTabularData = newGrid.automationTabularData as AdvancedDataGridTabularData: [object AdvancedDataGridTabularData]
var columnId:Array = datas.columnNames as Array: @objectName,@customObjectType,@owner,@value0,@value1,@icon1,@value2,@icon2,@value3,@icon3,@value4,@icon4,@value5,@value6,@icon6,empty
var gridView:HierarchicalCollectionView = grid.dataProvider as HierarchicalCollectionView: [object HierarchicalCollectionView]
var gridData:HierarchicalData = gridView.source as HierarchicalData: [object HierarchicalData]
var gridArrayColl:ArrayCollection = gridData.source as ArrayCollection: null
然后它失败了，因为它无法获取源代码，我认为。我对其他策略完全开放，我已经在这个问题上停留了 10 天。这似乎相对容易。提前感谢您的任何意见。
** 更新 **
我一直在走一条稍微不同的路线。我现在正在尝试使用光标遍历 HierarchicalCollectionView。这似乎有效。但是，当我得到节点时，我无法用它做任何有用的事情......我一直在寻找示例，但到目前为止，它们都停在了获取节点的位置。这意味着我知道这是一个愚蠢的问题。
public static function assertTextInAdg(params:Object):Boolean{
// Gets the ADG
trace('youre in the assertTextInAdg function');
var grid:* = FPLocator.lookupDisplayObject(params);
trace('var grid:* = FPLocator.lookupDisplayObject(params): ' + grid);
var adgData:* = grid.hierarchicalCollectionView;
trace('var adgData:* = grid.hierarchicalCollectionView: ' + adgData);
trace('AdgData.length() = ' + adgData.length);
var cursor:* = adgData.createCursor();
while(!cursor.afterLast) {
var node:Object = cursor.current;
cursor.moveNext();
}
这是 trace() 输出：
youre in the assertTextInAdg function
var grid:* = FPLocator.lookupDisplayObject(params): testApp.ApplicationSkin2._ApplicationSkin_Group1.contentGroup.Panel5.myADG
var adgData:* = grid.hierarchicalCollectionView: [object HierarchicalCollectionView]
AdgData.length() = 8
