If i declare an object for reactive
, this object will lose reactivity when i change this object direct.
e.g. :
let obj = reactive({})
obj = reactive({a: 1})
watch(obj , (newVal, oldVal) => {
// do nothing...
})
I thought of two plans.
reactive
, use Ref
let obj = ref({})
obj.value = {a: 1}
watch(obj , (newVal, oldVal) => {
// changing
})
reactive
object in one reactive
objectlet state = reactive({
obj1: {}
obj2: {}
})
state.obj1 = {a: 1}
// You won't be able to use `watch`
// Because this will monitor to entire object
// Cause unnecessary trouble when you change object
watch(state , (newVal, oldVal) => {
// changing
})
This plan is only applicable when the wrapped reactive
object is used in the template.
I prefer the first plan. But it doesn't look elegant.
What about you? Or do you have a better plan?
