动态加载CSS文件以进行主题设置 [英] Load css file dynamically for theming

问题描述

我有三个具有不同颜色主题的css文件，例如 theme1.css theme2.css theme3.css

I have three css files with different color themes e.g. theme1.css theme2.css theme3.css

我要根据所选类别加载它们. 是否可以在angular2中动态加载CSS文件? 处理此问题的正确方法是什么?

I want to load them depending on the selected category. Is it possible to load css files dynamically in angular2? What´s the proper way to handle this?

谢谢！

推荐答案

我不确定这是否正确.但是您可以尝试这样-

I am not sure if this is proper way. But you can try like this-

    import { Component, Inject } from '@angular/core';
    import { DOCUMENT } from '@angular/platform-browser';

    @Component({
    })

    export class SomeComponent {

        constructor (@Inject(DOCUMENT) private document) { }

        LightTheme() {
            this.document.getElementById('theme').setAttribute('href', 'light-theme.css');


        DarkTheme() {
            this.document.getElementById('theme').setAttribute('href', 'dark-theme.css');
    }
}

参考: https://angular. io/docs/ts/latest/api/platform-b​​rowser/index/DOCUMENT-let.html

看看这是否有帮助.
