使用角度材料以角度2将行从一张桌子转移到另一张桌子

本文介绍了使用角度材料以角度2将行从一张桌子转移到另一张桌子的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我已使用角材料在角度2中实现了简单表...我采用了两个mat-table，其中单击移至表2"时将第一张表中的选定行转移到第二个表，单击移至表"中则反之亦然1

但是，当我选择并单击Move To Table 2时，我的第一张表中的行将被拼接和传输，但是与第二行中的行相同，我将在第二张表中再次获得先前传输的行./p>

示例示例

下面显示的是我的输出.

最初，当我转移第一行时，它会被拼接并移到第二张表中.

但是当我转移第二行时，先前移动的行会再次添加到第二张表中.

解决方案

那是因为您没有清除选择内容，

从一张桌子到另一张桌子的转移完成后，您需要做的就是清除选择

在moveToTableTwo()的末尾添加this.selection.clear();，例如:

moveToTableTwo(){ ... this.selection.clear(); }

I have implemented simple table in angular 2 using angular material...I have taken two mat-table where the selected rows from first table are transferred to second table on clicking Move To Table 2 and vice versa on clicking Move To Table 1

But as I select and Click on Move To Table 2 , the row from my first table is getting spliced and transferred but as do the same for the second row, I am getting the previously transferred row again in my second table.

Sample Example

Below shown is my output.

Initially when I transfer first row , its getting spliced and moved to second table .

But when I transfer second row ,the previously moved row is again added in the second table.

解决方案

That is because you are not clearing the selection ,

All you need to do is clear the selection once the transfer from one table to another is finished

Add this.selection.clear(); this at the end of moveToTableTwo() , like :

moveToTableTwo(){ ... this.selection.clear(); }
