This key-value mode cannot be monitored by vue. . .
You can use $set to change the value inside
this.$set(object, key value, new value)

I don’t know if it’s a cache problem

Check to see if there are errors in the compilation. If it is compiled correctly, use ctrl+F5 to force refresh the page.

It is recommended that when you ask a question, describe the problem clearly and specifically. data.json has been modified (where is the modified data), but the dom is not updated (neither is updated or a certain part is not updated), three major pieces of code It is inconvenient for people who want to help you solve the problem to quickly locate the problem. Is it a binding problem? Use v-bind:xxx instead of:xxx
