Angular 2中的ng-list等效项 [英] ng-list equivalent in Angular 2

问题描述

很难找到有关此文档的信息，但是在Angular 1中，您可以执行以下操作:

Having a difficulty finding documentation on this, but in Angular 1 you could do:

<textarea ng-model="name" ng-list=","></textarea>

然后输入，如果您要输入"Hello，world！" name将是["Hello", "world!"]的数组.

Then on input, if you were to enter "Hello, world!" name would be an array of ["Hello", "world!"].

我的目标是将ng-list与HTML实体
一起使用，以将textarea按行拆分为一个数组.请参阅文档中的示例.

My goal is to use ng-list with the HTML entity 
 for breaking a textarea by line into an array. See example from docs.

Angular 2中有与之等效的东西吗?

Is there an equivalent of this in Angular 2?

推荐答案

找不到本机解决方案，但是您可以使用(ngModelChange)，然后像这样获取解析后的值:

Could not find native solution, but you can use (ngModelChange) and then get the parsed value like this:

  parseTextArea() {
     this.textareaParsed = this.textarea.split("\n");
  }

并在您的模板中:

<textarea [(ngModel)]="textarea" (ngModelChange)="parseTextArea()"></textarea>

请参阅以下示例:文本区域示例(在Chrome中，具有一些config.js问题 ...)
