判断、v-if判断显示隐藏,功能区循环案例。

判断条件

1.第一种

如果身份是管理员 ， 那么全部显示

如果身份是员工 ，那么除了value等于1的全部都显示

v-if="( user.state.level ==='admin') || ( user.state.level === 'staff' && item.value !== 1)"

<view class="funcBox">
	<block v-for="(item,index) in funcList" :key="index">
		<view class="item" @click="toFunc(item)" v-if="( user.state.level ==='admin') || ( user.state.level === 'staff' && item.value !== 1)">
			<image :src="item.img" mode="scaleToFill"></image>
			<view class="funcTxt">{{item.title}}</view>
		</view>
	</block>
</view>

2.根据数据判断

v-if="item.isShow"

<view class="funcBox">
	<block v-for="(item,index) in funcList" :key="index">
		<view class="item" @click="toFunc(item)" v-if="item.isShow">
			<image :src="item.img" mode="scaleToFill"></image>
			<view class="funcTxt">{{item.title}}</view>
		</view>
	</block>
</view>

const funcList = ref([{
		value: 1,
		img: '/static/images/index1.png',
		title: '第一个',
		path: '',
		isShow: user.state.level === 'staff' ? false : true
	}, {
		value: 2,
		img: '/static/images/index2.png',
		title: '第二个',
		path: '/pages/index/device/list',
		isShow: true
	}, {
		value: 3,
		img: '/static/images/index3.png',
		title: '第三个',
		path: '',
		isShow: true
	}, {
		value: 4,
		img: '/static/images/index4.png',
		title: '第四个',
		path: '',
		isShow: user.state.level === 'staff' ? false : true
	}])
