javascript - Aurelia 简单绑定(bind)不起作用

Question

我有一个非常简单的绑定(bind)，但它没有像我期望的那样工作:

app.js:

export class PupilsViewer {

    pupilsInfo = [
        { name: 'John' },
        { name: 'Eric' },
        { name: 'Martin' },
        { name: 'Simon' }
    ];

}

app.html:

<template>
    <require from="./pupil"></require>
    <pupil repeat.for="pupilInfo of pupilsInfo" info="${pupilInfo}"></pupil>
</template>

pupil.js:

import {bindable} from 'aurelia-framework';

export class Pupil {
    @bindable info = { name: 'unknown' };
}

pupil.html:

<template>
    <div>Name: ${info.name}</div>
</template>

这会产生以下输出:

Name: unknown
Name: unknown
Name: unknown
Name: unknown

虽然我预料到了:

Name: John
Name: Eric
Name: Martin
Name: Simon

Answer 1

现在我也遇到了同样的问题。这似乎是一个打字错误问题。尝试更改或删除可绑定(bind)项的驼峰式大小写。但你的绑定(bind)也不行。

export class PupilsViewer {

    pupils = [
        { name: 'John' },
        { name: 'Eric' },
        { name: 'Martin' },
        { name: 'Simon' }
    ];

}

app.html

<template>
    <require from="./pupil"></require>
    <pupil repeat.for="pupil of pupils" info.bind="pupil"></pupil>
</template>

pupil.js

import {customElement, bindable} from 'aurelia-framework';

@customElement('pupil')
@bindable('info')
export class Pupil {

}
