JS實現數據定位查找，字段定位

 SearchUserTable() {
            var SearchUserText = RoleManage.SearchUserText.trim();
            if (SearchUserText.trim() == "") {
                RoleManage.tableUserData = RoleManage.tableUserAllData

            }//RoleManage.tableUserAllData存儲着顯示的所有數據
 else {
                RoleManage.tableUserData = RoleManage.tableUserAllData.filter(e => {
                    if (e.UserAccount.toUpperCase().indexOf(SearchUserText.toUpperCase()) >= 0) {
                        return true;
                    }
                });//filter是一個方法，indexof實現查找
            }


        },
