如何设定咆哮的寿命

Question

https://www.primefaces.org/primeng/#/growl

我试图让咆哮声显示3秒钟，我做错了什么？咆哮显示，但不会消失。

<form [formGroup]="editPostForm" >
    <div class="form-group">
        <label for="email">Title:</label>
        <input formControlName = "title" type="text" class="form-control" id="title">
    </div>
    <div class="form-group">
        <label for="post-body">Body:</label>            
        <p-editor formControlName="editor" [style]="{'height':'320px'}" id="text"></p-editor>            
    </div>
    <button type="button" (click)="savePost()" class="btn btn-primary" >Save</button>
    <p-growl [(value)]="msgs" [life]=3000></p-growl>
</form>

[更新]
设置生命属性的正确语法：

<p-growl [(value)]="msgs" life=3000 formControlName="gr1"></p-growl>

我不熟悉语法，但基于其他属性，你试过这些吗？

括号

[life]="3000"

引号和括号

[(life)]=3000
