有时需要将数据临时存储到本地缓存,而不是存储到数据库,
1、
<template>
<view>
<button type="primary" @click="setStor">存储数据</button>
</view>
</template>
<script>
export default {
methods: {
setStor () {
uni.setStorage({
key: 'id',
data: 100,
success () {
console.log('存储成功')
}
})
}
}
}
</script>
<style>
</style>
存储成功之后,浏览器中查看:Application>localstorage,微信开发者工具中查看:storage
2、
<template>
<view>
<button type="primary" @click="setStor">存储数据</button>
</view>
</template>
<script>
export default {
methods: {
setStor () {
uni.setStorageSync('id',100)
}
}
}
</script>
<style>
</style>
3、uni.getStorage
<template>
<view>
<button type="primary" @click="getStorage">获取数据</button>
</view>
</template>
<script>
export default {
data () {
return {
id: ''
}
},
methods: {
getStorage () {
uni.getStorage({
key: 'id',
success: res=>{
console.log("获取成功",res)
}
})
}
}
}
</script>
注意:res={data:key对应的内容}
4、
<template>
<view>
<button type="primary" @click="getStorage">获取数据</button>
</view>
</template>
<script>
export default {
methods: {
getStorage () {
const id = uni.getStorageSync('id')
console.log(id)
}
}
}
</script>
5、
<template>
<view>
<button type="primary" @click="removeStorage">删除数据</button>
</view>
</template>
<script>
export default {
methods: {
removeStorage () {
uni.removeStorage({
key: 'id',
success: function () {
console.log('删除成功')
}
})
}
}
}
</script>
6、
<template>
<view>
<button type="primary" @click="removeStorage">删除数据</button>
</view>
</template>
<script>
export default {
methods: {
removeStorage () {
uni.removeStorageSync('id')
}
}
}
</script>
