判断数组中有没有这个元素中的其中一个值,如果有就删除,如果没有就push
const arr2 = [{id: 1}, {id: 2}];
const value2 = {id: 3};
const index = arr2.findIndex(object => object.id === value2.id);
if (index === -1) {
arr2.push(value2);
}else{
arr.splice(index, 1)
}
const arr2 = [{id: 1}, {id: 2}];
const value2 = {id: 3};
const index = arr2.findIndex(object => object.id === value2.id);
if (index === -1) {
arr2.push(value2);
}else{
}
