Vue Warn]:属性“ iSmobileterminal”在渲染过程中访问,但未定义
我正在从事移动和PC的项目,我需要估算移动终端或PC终端。 fixible.js
import { computed } from 'vue'
import { PC_DEVICE_WIDTH } from '../constants'
import { useWindowSize } from '@vueuse/core/index'
const { width } = useWindowSize()
// 判断当前是否为移动设备,判断依据屏幕宽度是否小于一个指定宽度(1280)
export const isMobileTerminal = computed(() => {
return width.value < PC_DEVICE_WIDTH
})
和导航/索引。VUE代码是
<template>
<mobile-navigation v-if="isMobileTerminal"></mobile-navigation>
</template>
<script>
import { isMobileTerminal } from '../../../../utils/flexible'
import mobileNavigation from './mobile/index.vue'
export default {
name: 'index',
components: {
mobileNavigation
}
}
</script>
<style lang="scss" scoped></style>

I'm working on a project that's both mobile and PC,I need to estimate the mobile terminal or PC terminal。
flexible.js
import { computed } from 'vue'
import { PC_DEVICE_WIDTH } from '../constants'
import { useWindowSize } from '@vueuse/core/index'
const { width } = useWindowSize()
// 判断当前是否为移动设备,判断依据屏幕宽度是否小于一个指定宽度(1280)
export const isMobileTerminal = computed(() => {
return width.value < PC_DEVICE_WIDTH
})
and the navigation/index.vue code is
<template>
<mobile-navigation v-if="isMobileTerminal"></mobile-navigation>
</template>
<script>
import { isMobileTerminal } from '../../../../utils/flexible'
import mobileNavigation from './mobile/index.vue'
export default {
name: 'index',
components: {
mobileNavigation
}
}
</script>
<style lang="scss" scoped></style>

ismobileterminal
仅在您的组件中导入。还需要通过在组件定义中声明该模板来提供该模板。从
isMobileTerminal
is only imported in your component. It also needs to be made available to the template by declaring it in your component definition.Returning it from the
setup()
hook is one way to do that:
