sass or less Both provide variable settings. Use less or sass variables in projects that need to switch themes. As long as you modify the variable value, all styles using the variable will be modified to the effect you want after compilation. However, for projects built in vue-cli , introduce a scss file globally in main.js, define variables in it, and report variable undefined errors when referenced in other components or pages. Other styles can be displayed normally, which is obviously a compilation problem.
Foolish Reference
Introduce the global style file into every component that uses global variables
@import 'path/fileName.scss'
But the components or pages are not in the same directory, and the imported paths may be different, so let’s look at the solution of sass-resources-loader .
sass-resources-loader introduces sass global variables
sass-resources-loader can access sass resources and any sass module that needs to be accessed. So, you can use shared variables and mix all SASS styles without having to reference them in every file.
Install sass-resources-loader
npm install --save-dev sass-resources-loader
Modify sass configuration
at Find util.js in the build folder Modify the configuration of the sass compiler loader
// 全局文件引入 当然只想编译一个文件的话可以省去这个函数
function resolveResource(name) {
return path.resolve(__dirname, '../static/style/' + name);
}
function generateSassResourceLoader() {
var loaders = [
cssLoader,
'sass-loader',
{
loader: 'sass-resources-loader',
options: {
// 多个文件时用数组的形式传入，单个文件时可以直接使用 path.resolve(__dirname, '../static/style/common.scss'
resources: [resolveResource('common.scss')]
}
}
];
if (options.extract) {
return ExtractTextPlugin.extract({
use: loaders,
fallback: 'vue-style-loader'
})
} else {
return ['vue-style-loader'].concat(loaders)
}
}The call to modify the sass configuration isgenerateSassResourceLoader()
return {
css: generateLoaders(),
postcss: generateLoaders(),
less: generateLoaders('less'),
// vue-cli默认sass配置
// sass: generateLoaders('sass', { indentedSyntax: true }),
// scss: generateLoaders('sass'),
// 新引入的sass-resources-loader
sass: generateSassResourceLoader(),
scss: generateSassResourceLoader(),
stylus: generateLoaders('stylus'),
styl: generateLoaders('stylus')
}References the common.scss file in main.js , Restart the service, and the variables defined in it can be used in other components.

How to use function intercept vue
Apr 08, 2025 am 06:51 AM
Function interception in Vue is a technique used to limit the number of times a function is called within a specified time period and prevent performance problems. The implementation method is: import the lodash library: import { debounce } from 'lodash'; Use the debounce function to create an intercept function: const debouncedFunction = debounce(() => { / Logical / }, 500); Call the intercept function, and the control function is called at most once in 500 milliseconds.
