如何以角度 2 分割字符串 [英] How to split a string in angular 2

问题描述

我有一个电子邮件发送场景，其中有一个收件人"(您要向谁发送消息)的输入框.

I have an email sending scenario in which there is an input box of 'To'(whom you want to send a message).

app.html

 <input type="text" class="form-control" [(ngModel)]="email.Tos"> 

现在我希望当用户在输入框中输入多个 emailId 时以逗号分隔，然后在我的模型中，'Tos' 值应该绑定在一个字符串数组中.喜欢: ["abc@gmail,com" , "[e-mail]"].

Now I want that when a user input the multiple emailId in input box by comma separated, then in my model, 'Tos' value should bind in an Array of string. Like : ["abc@gmail,com" , "[e-mail]"].

现在，请告诉我如何根据我的要求拆分输入框值.

Now, please tell me how to split the input box value as per my requirement.
