power bi - 自定义视觉 - 矩阵选择不更新其他视觉

相同的问题

我尝试使用我的矩阵自定义视觉对象创建选区，但在其他视觉对象上会出错

这是我的转换，使用构建器 withMatrixNode

function visualTransform(options: VisualUpdateOptions, host: IVisualHost): DataViewModel {

let dataViews = options.dataViews[0];
var rows = dataViews.matrix.rows;
let listSelectionId: DataListSelection[] = [];
let selectionIdBuilder = host.createSelectionIdBuilder();

rows.root.children.forEach(x => {
    listSelectionId.push({
        value: x.value,
        selectionId: selectionIdBuilder.withMatrixNode(x, rows.levels).createSelectionId()
    });

    if (x.children)
        x.children.forEach(z => {
            listSelectionId.push({
                value: z.value,
                selectionId: selectionIdBuilder.withMatrixNode(z, rows.levels).createSelectionId()
            });
            if (z.children)
                z.children.forEach(a => {
                    listSelectionId.push({
                        value: a.value,
                        selectionId: selectionIdBuilder.withMatrixNode(a, rows.levels).createSelectionId()
                    });

                })
        })
});
return {
    dataPoints: listSelectionId
}

}

我已经添加点击侦听器以获取选择 ID 并在管理器中将其选中，这是控制台日志

但是我的页面在其他视觉中总是出错：

我的选择代码有什么问题？ 还有一个问题，我已经在我的管理器中声明了 selectcallback 但从未在其他视觉对象进行选择时调用

this.selectionManager = this.host.createSelectionManager();
    console.log('constructor allow interaction', this.host.allowInteractions);
    this.selectionManager.registerOnSelectCallback(() => {
        console.log('selection manager callback', this.selectionManager.getSelectionIds());
    });
    this.selectionIdBuilder = options.host.createSelectionIdBuilder();

Answer 1

通过移除 let

解决这个问题

let selectionIdBuilder = host.createSelectionIdBuilder();
