在Iron Router中的this.render()之后访问HTML [英] Access HTML after this.render() in Iron Router

问题描述

我需要在新渲染的模板上应用一些语义UI，但是我不知道如何从路由器获取渲染的HTML.这是我的代码:

I need to apply some Semantic UI on newly rendered templates, but I have no idea how to get the rendered HTML from the router. Here's my code :

Router.route('/', {
  name: 'home',

  where: 'client',

  action: function () {

    this.render('home');
  },

  onAfterAction: function () {

    console.log( $('#homeSidebar') );

  }

});

基本上，$('#homeSidebar')应该返回侧边栏元素，但由于HTML尚不可用，因此不返回任何内容.到目前为止，唯一的解决方案是像这样更改功能

Basically, $('#homeSidebar') should return the sidebar element, but it returns nothing as the HTML is not yet available. The only solution, so far, was to change the function like this

  onAfterAction: function () {
    setTimeout(function () {
      $('#homeSidebarToggle').on('click', function () {
        $('#homeSidebar').sidebar('toggle');
      });
    }, 200);    
  }

既不干净也不安全. HTML可用后如何立即运行功能?

Which is neither clean nor safe. How can I run a function immediately as soon as the HTML is availble?

推荐答案

您应在模板上使用onRendered回调.流星使用模板helpers, events and callbacks来操作DOM.铁路由器仅用于路由)
您的client/view.html:

You should use onRendered callback on the template. Meteor uses template helpers, events and callbacks for manipulating DOM. Iron Router is just for routing)
Your client/view.html:

<template name="home">
  <div id="homeSidebar">

  </div>
</template>

您的client/view.js:

Your client/view.js:

Template.home.onRendered(function () {
  console.log($('#homeSidebar'));
});
