流星：如何在车把内使用车把

Question

I would like to use to refer to another template within an {{#each}} loop

html:

{{#each listOfItems}}
 {{>{{variableOne}}}}
{{/each}}

which should render

<Template name="one">
 One
</Template>

or

<Template name="two">
 Two
</Template>

depending on the js

other tried syntax include

{{>'{{variableOne}}'}}

or

{{>Template.dynamic template={{variableOne}}}}

Any help or workaround greatly appreciated!

Answer 1

Not sure what are you trying to accomplish. I'm assuming you are using Blaze rendering engine. If you want to pass parameters try this:

{{#each}}
  {{> TemplateName variable=variable}}
{{/each}}

Or if you want to show certain template depending on variable value try this (watch out - eq is meant as global helper for comparing values):

{{#each}}
  {{#if variable eq 1}}
    {{> TemplateOne}}
  {{else}}
    {{> TemplateTwo}}
  {{/if}} 
{{/each}}

Assuming that the list you iterate over contains the template names, this will get you what you want:

html:

<template name="hello">
  {{#each template in myTemplates}}
    {{> Template.dynamic template=template }}
  {{/each}}
</template>

<template name='foo'>foo-template</template>
<template name='bar'>bar-template</template>

js:

Template.hello.helpers({
  myTemplates() {
    return ['foo', 'bar'];
  },
});
