问题描述

我在页面中有3个'mat-slider'，我希望滑块具有3种不同的颜色.我无法覆盖页面(组件)的主题颜色，因为它将应用于所有滑块.我必须为滑块制作3个不同的组件，并在每个组件中覆盖主题颜色吗?最简单的方法是什么?下面是我的角度版本和包装版本，

i have 3 'mat-slider's in a page and i want to have 3 different colors for the sliders. i cant override the theme colors for the page(component) as it will apply to all the sliders. do i have to make 3 different components for the sliders and override theme colors in each? what is the easiest way to achieve this? below are my angular and package versions,

推荐答案

这可能不是最好的方法，但是当您要求这里提供最简单的方法时，便是解决方案.

This may not be the best way but as you ask for the easiest way here is a solution.

给每个滑块一个类:

// home.component.hmtl
<mat-slider class="mat-slide-1"></mat-slider>
<mat-slider class="mat-slide-2"></mat-slider>
<mat-slider class="mat-slide-3"></mat-slider>

在styles.scss中引用这些类，并在每个类中定义要更改其颜色并使其重要的元素:

In your styles.scss reference these classes and in each class define the element you wish to change the colour of and make it important:

// styles.scss
.mat-slide-1 {
    .mat-slider-thumb {
        background-color: red !important;
    }
}

.mat-slide-2 {
    .mat-slider-thumb {
        background-color: yellow !important;
    }
}

.mat-slide-3 {
    .mat-slider-thumb {
        background-color: green !important;
    }
}

此示例仅更改拇指的颜色，但检查滑块的元素以查找与要更改的元素相关的类.

This example only changes the colour of the thumb but inspect the elements of the slider to find the class relevant to the element you want to change.

更正确的解决方案是使用多个主题并将它们分别应用于每个组件.请参考材质文档.

A more correct solution would be using multiple themes and applying them separately to each component. Refer the material docs.
