typescript - Angular : Multiline string

Question

我是 Angular 2 初学者，我在我的 dev/app.component.ts 中编写了这段代码:

import {Component} from 'angular2/core';

@Component({
    selector: 'my-app',
    template: '<h3 (click)="onSelect()"> {{contact.firstName}} {{content.lastName}}</h3>'
})
export class AppComponent {
    public contact = {firstName:"Max", lastName:"Brown", phone:"3456732", email:"max88@gmail.com"};

    public showDetail = false;
    onSelect() {
        this.showDetail=true;
    }
}

当我转到浏览器“显示 Max Brown”时，它起作用了。

现在，我想像这样在不同的行中编写模板部分:

import {Component} from 'angular2/core';

@Component({
    selector: 'my-app',
    template: '<h3 (click)="onSelect()">
    {{contact.firstName}} {{contact.lastName}}<h3>'
})
export class AppComponent {
    public contact = {firstName:"Max", lastName:"Brown", phone:"3456732", email:"max88@gmail.com"};

    public showDetail = false;
    onSelect() {
        this.showDetail=true;
    }
}

但我在 Chrome 控制台中收到此错误:

Uncaught TypeError: Cannot read property 'split' of undefined

Answer 1

将文本包裹在 `(反引号)中而不是单引号 ' 中，然后它可以跨越多行。

var myString = `abc
def
ghi`;
