My Vuex store has a state variable called scannedList, which is initially set to an empty array []:
state: {
scannedList: []
}
I have a mutation that adds ids to this array. I attempted to clear the entire state by using:
store.commit('addToScannedList', [])
However, the ids are still present in the array. What is the correct way to achieve this?
To clear an array by pushing an empty array onto it is not effective. Instead, you can create a new mutation like this:
clearScannedItems(state) {
state.scannedList = [];
}
Alternatively, you can modify your existing mutation to handle clearing the array when no payload is passed:
addScannedItem(state, item) {
if(item !== undefined) {
state.scannedList.push(item);
} else {
state.scannedList = [];
}
}
You can trigger this mutation using store.commit('addScannedItem') without passing any payload.
