电容器变量主题未使用

问题描述 投票:0回答:1

我已从 Cordova 升级到 Capacitor 并使用 Angular。 我的 Variables.scss 文件中的主题没有被使用。 它使用的是 node_modules/@ionic/angular/css/core.css 中的主题。

因此,当对下面的颜色应用“primary”时,它不会使用variables.scss文件中设置的“ion-color-primary”。 它使用 core.css 文件中设置的颜色。

<ion-header mode="md"
            class="ion-no-border">
    <ion-toolbar color="primary">
        <ion-buttons slot="start">
            <ion-menu-button></ion-menu-button>

我错过了什么?

文件夹结构在src/theme中有variables.scss

我有一个变量.scss:

:root {
  --ion-color-primary: #007eae;
  --ion-color-primary-rgb: 0,126,174;
  --ion-color-primary-contrast: #ffffff;
  --ion-color-primary-contrast-rgb: 255,255,255;
  --ion-color-primary-shade: #006f99;
  --ion-color-primary-tint: #1a8bb6;
  --ion-color-secondary: #0cd1e8;
  --ion-color-secondary-rgb: 12,209,232;
  --ion-color-secondary-contrast: #ffffff;
  --ion-color-secondary-contrast-rgb: 255,255,255;
  --ion-color-secondary-shade: #0bb8cc;
  --ion-color-secondary-tint: #24d6ea;

看起来您的variables.scss已正确设置,但您的样式加载或覆盖方式可能存在问题。您可以检查以下几项来解决问题:

1。确保variables.scss正确加载:

您的 angular.json 文件包含变量.scss,这很好,但请确保它列在其他 Ionic 样式表之前。在您当前的配置中,它已经是列表中的第一个样式表,因此这应该可以工作,但请仔细检查 src/theme/variables.scss 是否正在正确处理。

2。使用ionic.config.json进行主题设置:

如果您要覆盖 Ionic 的默认主题变量,请确保使用正确的配置并确保其他导入的文件不会产生冲突。

在 ionic.config.json 中,如有必要,您可以明确提及变量.scss 的路径:

{
  "name": "my-app",
  "type": "angular",
  "integrations": {
    "capacitor": {}
  },
  "theme": {
    "variables": "src/theme/variables.scss"
  }
}

3.检查 src/theme/variables.scss 中是否缺少变量:

确保您的变量定义正确并且没有拼写错误或问题。格式应该是这样的:

:root {
  --ion-color-primary: #007eae;
  --ion-color-primary-rgb: 0,126,174;
  --ion-color-primary-contrast: #ffffff;
  --ion-color-primary-contrast-rgb: 255,255,255;
  --ion-color-primary-shade: #006f99;
  --ion-color-primary-tint: #1a8bb6;
}

此外,检查其他 CSS 文件中可能发生的任何 ion-color-primary 覆盖。

4。检查浏览器的开发者工具:

使用浏览器的开发人员工具(例如 Chrome DevTools)检查应用于离子工具栏的样式并检查原色的来源。如果应用了 core.css,则可能会在那里设置颜色,从而覆盖您的自定义主题。查找 --ion-color-primary 变量并确保正确应用它。

5。清除缓存并重建应用程序:

有时,由于缓存的原因,样式表中的更改可能不会立即生效。尝试清除浏览器缓存或重建应用程序:

npm run build
npx cap sync

6。自定义 Webpack 配置:

由于您使用的是自定义 Webpack 配置,请确保 Variables.scss 正确包含在您的 Webpack 设置中。您可能需要修改 webpack.config.js 以将其包含为所有组件的全局样式表。

SCSS 的 Webpack 配置示例:

module.exports = {
  // Other configurations...
  module: {
    rules: [
      {
        test: /\.scss$/,
        use: [
          'style-loader',
          'css-loader',
          {
            loader: 'sass-loader',
            options: {
              additionalData: `@import "src/theme/variables.scss";`
            }
          }
        ]
      }
    ]
  }
};

7。检查范围问题:

如果您仍然遇到问题,请确保样式的范围不正确。例如,如果您使用 Angular 的 ViewEncapsulation,它可能会阻止应用全局样式。您可以通过将以下内容添加到组件来禁用它:

import { Component, ViewEncapsulation } from '@angular/core';

@Component({
  selector: 'app-my-component',
  encapsulation: ViewEncapsulation.None,
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.scss']
})

8。调试技巧 - 覆盖组件中的样式:

作为临时调试步骤,尝试使用组件样式表中的 CSS 自定义属性直接应用样式:

ion-toolbar {
  --background: var(--ion-color-primary);
}

这些步骤应有助于确保您的自定义主题在您的应用程序中正确应用。如果您需要进一步帮助,请告诉我!
