示例1: function
export default function(state = INITIAL_STATE, action) {
switch(action.type) {
case PUSH_DATA:
const { keys, values } = action.payload;
return SI.from(INITIAL_STATE).merge({keys, values}, {deep: true})
case EDIT_DATA:
const { id, field, value } = action.payload;
return SI.from(state).setIn(['values', id, field], value)
case NEW_NODE:
return SI.from(state).merge(action.payload, {merger: mergers.concatArrayMerger, deep: true})
}
return state;
