Vue.js, refresh the page and the data in data will be restored.
data(){
return {
value: "",
}
},I have a component"s data data value,. When I"m in this component, I use button events to add data to it
click_btn(){
this.value = this.value + "123"
}
but when I refresh the browser page, it reverts to the previous empty string. How to solve this problem?
click_btn(){
this.value = this.value + '123'
window.sessionStorage.setItem('val',this.value)
}mounted(){
if(window.sessionStorage.getItem('val')){
this.value = window.sessionStorage.getItem('val');
}
}data is stored in memory, and will definitely be recovered after refreshing. It can only be persisted, and can only be stored in localstorage or cookie
