角2不给复选框的当前状态 [英] Angular 2 not giving current state of checkbox

问题描述

我已经开始建立一个待办事项示例应用程序。我面临着一个奇怪的问题。
下面是HTML code的待办事项列表。在该列表中我设置为ngModel复选框，并触发一个更改事件也是如此。

I have started building an ToDo sample app. I am facing an strange issue. Below is the HTML code for the ToDo List. In that list i am setting ngModel for checkbox and firing an change event as well.

code听的变化。我只打印出当前状态到控制台。

Code to listen the change. I am only printing the current state to console.

看下面的图片可以看到的复选框的当前状态进行检查，但在控制台我得到复选框的previous状态。

Look at below image you can see the current state of the checkbox is checked but in console i am getting the previous state of the checkbox.

请告诉我什么是有工作的正确途径。

Please tell me what is the correct approach to have that working.

有喜欢使用不同的解决方法 event.target.value 而不是从模型的价值。

There are different workarounds like using event.target.value instead of the value from the model.
