问题描述
如何使Iron:router重新渲染模板?
How can I make Iron:router re-render a template?
我有这个html:
<head>
</head>
<body>
</body>
<template name="mainLayout">
<a href="{{pathFor route='list'}}">list</a>
<a href="{{pathFor route='find' query='q=xxx'}}">find</a>
{{> yield}}
</template>
<template name="listTemplate">
<p>list</p>
</template>
和这个js:
Router.configure({
layoutTemplate: 'mainLayout'
});
Router.route('/list', {
name: 'list',
template: 'listTemplate'
});
Router.route('/find', {
name: 'find',
template: 'listTemplate',
data: function () {
return this.params.query;
}
});
if (Meteor.isClient) {
Template.listTemplate.rendered = function () {
if (this.data)
console.log('find ' + this.data.q);
else
console.log('list all');
};
}
当我单击链接以切换视图时(此处在console.log中进行了模拟)，路由确实发生了变化，但是模板没有重新呈现. 有没有办法强制iron:router重新渲染?
When I click on the links to switch views (simulated here with console.log), the route does change, but the template is not re-rendered. Is there a way to force iron:router to re-render?
推荐答案
设置路由器控制器状态对我不起作用.答案AntônioAugusto Morais 给出了相关的
Setting the router controller state did not work for me. The answer Antônio Augusto Morais gave in this related github issue worked. Using the Session to store the reactive var to trigger the autorun reactiveness. It's a hack, but it works.
## router.coffee
Router.route '/profile/:_id',
name: 'profile'
action: ->
Session.set 'profileId', @params._id
@render 'profile'
## profile.coffee
Template.profile.onCreated ->
@user = new ReactiveVar
template = @
@autorun ->
template.subscription = template.subscribe 'profile', Session.get 'profileId'
if template.subscription.ready()
template.user.set Meteor.users.findOne _id: Session.get 'profileId'
else
console.log 'Profile subscription is not ready'
Template.profile.helpers
user: -> Template.instance().user.get()
## profile.html
<template name="profile">
{{#if user}}
{{#with user.profile}}
<span class="first-name">{{firstName}}</span>
<span class="last-name">{{lastName}}</span>
{{/with}}
{{else}}
<span class="warning">User not found.</span>
{{/if}}
</template>
