const list = {
state: {
list: []
},
mutations: {
update: (state, e) => {
for (let i = 0; i < state.list.length; iPP) {
//
// state.list[i] = { ...e, ...state.list[i] }
for (const ii in e) {
state.list[i][ii] = e[ii]
}
}
}
}
}
export default list state.list is originally an empty array, state.list [I] can assign values,
but if state.list [I] is empty, state.listi = e [ii] directly;
will not find the ii' attribute corresponding to state.list [I], state.list [I] has not been defined and its memory space has not been allocated.
should state.list [I] = {} first. Then assign the value, or directly use the subject state.list [I] = {... e,... state.list [I]} literally.
you use Vue.set (state.list,i, {... eMagne.state.list [I]}).
