what can I do because I can"t operate dom to add baby and automatically disappear in 3 hours? Ask for advice
/ / Please paste the code text below (do not replace the code with pictures)
add a time field to the data, then use the timer to traverse the list data every second, compare the current time with the addition time of each item in the list, and delete the data in more than 3 hours.
if the user is on this page all the time, you can use setTimeout
if you close the page and then open it, you can continue to save the monitoring time for more than 3 hours, which requires background cooperation, or use browser cache
there is no dom, that can be directly manipulated in Mini Program. You can only modify the data to change the front-end rendered page
if you want to not display a certain content after a certain period of time. You can use the wx:if condition for this content when displaying, and modify the display condition regularly to achieve
such as
<view wx:if="{{showThisView}}"></view>page
showThisView: truechange showThisView to false through setData after a certain time (you decide the business logic here).
