Meteor

Question

我正在尝试做这样的事情：

<template name=week>
   {{#each days}} //from an array in helpers with values [0,1,2,3,4,5,6]
      {{> day dayOfWeek="<How can I have the value here?>"}}
   {{/each}}
<template name>

问题1：如何获取数组的当前值并将其传递给包含的模板？

<template name=day>
   {{#autoForm collection=users doc=user ...}}
      {{#each days}} //from an array in helpers with values [0,1,2,3,4,5,6]
         {{>afFieldInput name='profile.availability.<dayOfWeek>.from'}}
      {{/each}}
   {{/autoForm}}
<template name>

问题2：如何动态替换名称中的dayOfWeek？

Answer 1

试试这个：

问题 1：

<template name="week">
  {{#each days}} //from an array in helpers with values [0,1,2,3,4,5,6]
    {{> day dayOfWeek=this}}
  {{/each}}
<template name>

问题 2：

HTML

<template name="day">
  {{#autoForm collection=users doc=user ...}}
    {{#each day in days}} //from an array in helpers with values [0,1,2,3,4,5,6]
      {{> afFieldInput name=name}}
    {{/each}}
  {{/autoForm}}
<template name>

ES2015

Template.day.helpers({
  name(){
    const dayOfWeek = this.dayOfWeek;
    return `profile.availability.${dayOfWeek}.from`;
  }
});

注意：这是使用最新的 Blaze 构造和来自 Meteor 1.2 的 ES2015

Meteor - 在模板参数中传递变量

Meteor - Pass variable in templates arguments
