angular2从后端配置获取组件css [英] angular2 get component css from backend configuration

问题描述

是否有从后端配置中获取组件CSS的方法?就像liferay

Is there a way to get component css from the Backend configuration? like liferay

我有一个组件，该组件提供文本框供用户输入CSS代码.无论CSS用户在texbox中输入的内容都应反映在组件中.

I have a component and this component provides textbox for the user to enter css code. Whatever css user enters in the texbox should reflect in component.

组件html

<div>
<h1>I am h1 tag<h1>
<h2>I am h2 tag<h2>
<div>

推荐答案

没有人回答，所以回答了我自己的问题.其实这很简单.只需创建一个样式标签并应用css

No one answered so answering my own question. Actually this is very simple. Just create a style tag and apply css

<div id="dynamicStyle">
<h1>I am h1 tag<h1>
<h2>I am h2 tag<h2>
<div>

组件

export class SomeComponent implements OnInit {
  color = 'red';
  ngOnInit() {
    const css = `h2 {color: green} img {background: ${this.color}`; // we can get this css from backend also
    const head = document.getElementById('dynamicStyle');
    const style = document.createElement('style');
    style.type = 'text/css';
    style.appendChild(document.createTextNode(css));
    head.appendChild(style);
  }
}
