Question

当我尝试编辑Prime NG的可编辑行中的某些行时，我遇到了一个奇怪的问题

如果我们看下面的网格，我们可以看到所有行都有不同的值：

firstGrid

如果我编辑第一行，显然没有问题：

secondGrid

但是，如果我尝试一次编辑几行，则所有行都将显示为相同的值：

thirdGrid

仅当网格位于p-dialog标签内时，才会发生此问题。

            </div>
          </ng-template>
        </p-table>

正如我之前所说，当表位于p-dialog标签之外时，不会发生此问题。但我需要坚持下去。

提前谢谢。

editPropertyValue方法：

editPropertyValue(equipmentClass: EquipmentClass) {
    this.EquipmentClassClone[equipmentClass.equipmentClassId] = {...equipmentClass}
  }

Answer 1

经过几天的努力，我终于找到了问题的原因。

对于那些面临此问题的人，答案是：

可编辑表不能在form标记内。我从表格中删除了整个表格，并且可以正常工作。
