AdvancedDatagrid multipleSelection：是否已选择一行？

发布于 2024-09-04 11:03:22 字数 655 浏览 8 评论 0原文

在高级数据网格中进行多次选择后，我想检查单击的行是否已被选择。无论如何，我下面的想法（在嵌套的 if 子句中，我想检查新单击的项目的处理数据是否已经在添加的数组集合中）不起作用，但我认为必须有更好的方法来区分是否单击了已选择的行。

可能我的描述不够清楚，请提问！

非常感谢，已经提前了，维尔纳

model.processingData = out; 
if    (model.selectedIndices.length > 1){                   
       //check if item already added
       var tempInt:int = model.multipleProcessingData.getItemIndex(model.processingData);
        if (tempInt == -1){
            model.multipleProcessingData.addItem(model.processingData);
        }

 } else{
       model.multipleProcessingData.removeAll();
       model.multipleProcessingData.addItem(model.processingData);
 }

after multiple Selection in a advanced datagrid, I want to check if the clicked row, was already selected. Anyway my idea below (in the nested if clause I want to check if the newly clicked item's processing data is already in the added Array Collection) is not working, but I assume there must be a better way to differiante if an click was made on a already selected row.

Probably I was not as clear in my description as needed, please ask your questions!

Thank you very much, already in advance,
Werner

       var tempInt:int = model.multipleProcessingData.getItemIndex(model.processingData);
        if (tempInt == -1){
            model.multipleProcessingData.addItem(model.processingData);
        }

 } else{
       model.multipleProcessingData.removeAll();
       model.multipleProcessingData.addItem(model.processingData);
 }

tssss，ArrayCollection 有一个 contains 函数：

if (!model.selectedDrawings.contains(model.lastSelectedDrawing)){
                        model.selectedDrawings.addItem(model.lastSelectedDrawing);
                    }

tssss, there is a contains function for ArrayCollection:

if (!model.selectedDrawings.contains(model.lastSelectedDrawing)){
                        model.selectedDrawings.addItem(model.lastSelectedDrawing);
                    }
