如何在Meteor JS中单击特定菜单时渲染部分模板

Question

I am new to Meteor JS. How can I render particular template to particular part of web app, when menu clicked. I am using iron-router and layout template. Following layout is working fine. For example: When user click on 'Home'> 'Article' menu , I like to render Article template to mainContent region(address bar look like /myapp/Article). Also other menu item works same, when menu item clicked , particular template displays in mainContent part. How can I route this? I am not sure even it is possible, is there any other way or any better solution around this problem. router.js

Router.map(function(){this.route('home', {
path: '/',
layoutTemplate: 'homePageLayout',
yieldTemplates: {
  'myHeader': {to: 'header'},
  'mySideMenu': {to: 'sideMenu'},
  'myMainContent': {to: 'mainContent'},
  'myFooter': {to: 'footer'}
}

}); });

layout.html

<template name="homePageLayout">
<div class="container">
    <div class="row">
        {{> yield  region='header'}}
    </div>
    <div class="row">
        <div class="col-lg-3">
            {{> yield region='sideMenu'}}
        </div>
        <div class="col-lg-6">
            {{> yield 'mainContent'}}
        </div>
    </div>
    <div class="row">
        <footer>
            {{> yield region='footer'}}
        </footer>
    </div>
</div>

Answer 1

You are nearly there :)

<div class="col-lg-6">
    {{> yield 'mainContent'}}
</div>

change to

<div class="col-lg-6">
    {{> yield }}
</div>

This is the "main" yield. The iron router will render the template of the route here. To identify the template the IR should render, you can do 2 things.

Do nothing -> Then the Iron Router would render a template named equal to the route's name. In your case it would render the template "home".

Or specify the template for your router:

Router.map(function(){
    this.route('home', {
        path: '/',
        template: 'mySuperTemplateForThisRoute',
        layoutTemplate: 'homePageLayout',
        yieldTemplates: {
          'myHeader': {to: 'header'},
          'mySideMenu': {to: 'sideMenu'},
          'myMainContent': {to: 'mainContent'},
          'myFooter': {to: 'footer'}
        }
    });
});

Answer 2

I am dealing with my problem like this. here is my router.js

        Router.map(function(){
  this.route('home', {
  path: '/',
  layoutTemplate: 'homePageLayout',
  action: function(){
    this.render('myHeader', {to: 'header'});
    this.render('mySideMenu', {to: 'sideMenu'});
    this.render('home', {to: 'mainContent'});
    this.render('myFooter', {to: 'footer'});
  }
});

  this.route('showMission', {
    path: 'mission',
    layoutTemplate: 'homePageLayout',
    action: function(){
      this.render('myHeader', {to: 'header'});
      this.render('mySideMenu', {to: 'sideMenu'});
      this.render('mission', {to: 'mainContent'});
      this.render('myFooter', {to: 'footer'});
    }
  });

  this.route('showCompanyStructure', {
    path: 'companyStructure',
    layoutTemplate: 'homePageLayout',
    action: function(){
      this.render('myHeader', {to: 'header'});
      this.render('mySideMenu', {to: 'sideMenu'});
      this.render('companyStructure', {to: 'mainContent'});
      this.render('myFooter', {to: 'footer'});
    }
  });

  this.route('showDuties', {
    path: 'duties',
    layoutTemplate: 'homePageLayout',
    action: function(){
      this.render('myHeader', {to: 'header'});
      this.render('mySideMenu', {to: 'sideMenu'});
      this.render('duties', {to: 'mainContent'});
      this.render('myFooter', {to: 'footer'});
    }
  });
});

So when particular menu link is clicked it will rendered that template to the 'mainContent' field. It works fine. But I think there will be more good solution, my solution is repeating code, it may cause 'myheader' and 'myfooter' template loads more than once. I am not sure about it.
