react.js-REACT - 显示和过滤特定数据

默认情况下,我只想显示状态为Pending和的数据Not started。目前,所有数据都显示在我的表中,状态如下:Good, Pending, Not started(见图)。
但我也希望有可能Good通过在按钮旁边创建Apply一个切换开关来查看状态:Show good menus,(我已经制作了一个功能Toggle.jsx),这将提供查看所有状态的可能性Good。
我真的不知道该怎么做,这就是我现在所拥有的:
export default function MenuDisplay() {
const { menuId } = useParams();
const [selected, setSelected] = useState({});
const [hidden, setHidden] = useState({});
const [menus, setMenus] = useState([]);
useEffect(() => {
axios.post(url,{menuId:parseInt(menuId)})
.then(res => {
console.log(res)
setMenus(res.data.menus)
})
.catch(err => {
console.log(err)
})
}, [menuId]);
// If any row is selected, the button should be in the Apply state
// else it should be in the Cancel state
const buttonMode = Object.values(selected).some((isSelected) => isSelected)
? "apply"
: "cancel";
const rowSelectHandler = (id) => (checked) => {
setSelected((selected) => ({
...selected,
[id]: checked
}));
};
const handleClick = () => {
if (buttonMode === "apply") {
// Hide currently selected items
const currentlySelected = {};
Object.entries(selected).forEach(([id, isSelected]) => {
if (isSelected) {
currentlySelected[id] = isSelected;
}
});
setHidden({ ...hidden, ...currentlySelected });
// Clear all selection
const newSelected = {};
Object.keys(selected).forEach((id) => {
newSelected[id] = false;
});
setSelected(newSelected);
} else {
// Select all currently hidden items
const currentlyHidden = {};
Object.entries(hidden).forEach(([id, isHidden]) => {
if (isHidden) {
currentlyHidden[id] = isHidden;
}
});
setSelected({ ...selected, ...currentlyHidden });
// Clear all hidden items
const newHidden = {};
Object.keys(hidden).forEach((id) => {
newHidden[id] = false;
});
setHidden(newHidden);
}
};
const matchData = (
menus.filter(({ _id }) => {
return !hidden[_id];
});
const getRowProps = (row) => {
return {
style: {
backgroundColor: selected[row.values.id] ? "lightgrey" : "white"
}
};
};
const data = [
{
Header: "id",
accessor: (row) => row._id
},
{
Header: "Name",
accessor: (row) => (
{row.name}
)
},
{
Header: "Description",
//check current row is in hidden rows or not
accessor: (row) => row.description
},
{
Header: "Status",
accessor: (row) => row.status
},
{
Header: "Dishes",
//check current row is in hidden rows or not
accessor: (row) => row.dishes,
id: "dishes",
Cell: ({ value }) => value && Object.values(value[0]).join(", ")
},
{
Header: "Show",
accessor: (row) => (
)
}
];
const initialState = {
sortBy: [
{ desc: false, id: "id" },
{ desc: false, id: "description" }
],
hiddenColumns: ["dishes", "id"]
};
return (
);
}
这里是我的api中的jsonmenuId:1
:
[
{
"menuId": 1,
"_id": "123ml66",
"name": "Pea Soup",
"description": "Creamy pea soup topped with melted cheese and sourdough croutons.",
"dishes": [
{
"meat": "N/A",
"vegetables": "pea"
}
],
"taste": "Good",
"comments": "3/4",
"price": "Low",
"availability": 0,
"trust": 1,
"status": "Pending",
"apply": 1
},
//...other data
]
