A user name in one of my header components is obtained through localstorage, but it must be refreshed manually before it can be displayed. Can the component refresh and obtain data by itself?-sharp-sharp-sharp problem description
/ / Please paste the code text below (do not replace the code with pictures)
what you shouldn't think about is how to get it without refreshing it. If you save it in localStorage , you can try to get it in the parent component and pass it to the child component when the child component initializes
1. If rendering is slow at the beginning, you can use ide/components-dynamic-async.html-sharpad" rel=" nofollow noreferrer "> Asynchronous component
or use
this.$nextTick(()=>{
//
})2. If the data involves midway modification and the parent component is passed to the child component, then the child component uses watch to listen for the content passed by the parent component
do you mean that after a successful login, the information is written in localstorage, and the top component gets the data of localstorage, but the data is empty, and it will be fine after refreshing. I have encountered this kind of
