c# - 如何支持 'onblur' 和类似事件？

Question

我想做这样的事情:

<td contenteditable=true @onblur(async (txt) => { ... })>

但目前似乎只支持@onchange，并且当contenteditable内容改变时实际上不会触发。我想方法是有一个调用 C# 处理程序的 JS 处理程序，但我不知道是否可以通过这种方式进行通信。现在最好的选择是拥有一个具有“保存到数据库”的 onclick 处理程序的按钮吗？或者有更好的选择吗？

感觉有必要在 Blazor 中构建可用事件的备忘单....似乎与离开这里有关，因为添加了 onblur。
