使用findIndex查找并做一些操作

let findIndex = arrItemsApprover.findIndex(item=>item.zusrid===oObject.zusrid);

if (findIndex!==-1){
	arrItemsApprover.splice(findIndex, 1);
}

arrData.forEach(item => {
    if (selectApproveUserData.findIndex(i=>item.zusrid===i.zusrid) !== -1) {
        item.selected = true;
    }else{
        item.selected = false;
    }
});
