I am using an antd tree component my issue is if you search something in the search bar then you will get search results in that result if you check and up check any field what happens all previous data get unchecked whatever data is present into the search bar result that only data remain selected if it already select or you just select what my task is I don't want to get unchecked all previously selected checked that only field update that we change right now I don't have any idea how can I fix this if anybody knows anyway, also I added a complete code SandBox link below.
This is my search bar filter code
const hasSearchTerm = (n, searchTerm) =>
n.toLowerCase().indexOf(searchTerm.toLowerCase()) !== -1;
const filterData = (arr, searchTerm) =>
arr?.filter(
(n) =>
hasSearchTerm(n.title, searchTerm) ||
filterData(n.children, searchTerm)?.length > 0
);
function filteredTreeData(data, searchString, checkedKeys, setExpandedTree) {
let keysToExpand = [];
const filteredData = searchString
? filterData(data, searchString).map((n) => {
keysToExpand.push(n.key);
return {
...n,
children: filterData(n.children, searchString, checkedKeys)
};
})
: data;
setExpandedTree([...keysToExpand]);
return filteredData;
}
This issue happens when the check or unchecks field after searching in the search bar in this part of the code
const onCheck = (checkedKeysValue) => {
console.log("onCheck", checkedKeysValue);
setCheckedKeys(checkedKeysValue);
};
const Demo = () => {
const [expandedKeys, setExpandedKeys] = useState([]);
const [checkedKeys, setCheckedKeys] = useState([]);
const [selectedKeys, setSelectedKeys] = useState([]);
const [autoExpandParent, setAutoExpandParent] = useState(true);
const [searchValue, setSearchValue] = useState("");
const [tree, setTree] = useState(treeData);
const onExpand = (expandedKeysValue) => {
console.log("onExpand", expandedKeysValue); // if not set autoExpandParent to false, if children expanded, parent can not collapse.
// or, you can remove all expanded children keys.
setExpandedKeys(expandedKeysValue);
setAutoExpandParent(false);
};
const onCheck = (checkedKeysValue) => {
console.log("onCheck", checkedKeysValue);
setCheckedKeys(checkedKeysValue);
};
const onSelect = (selectedKeysValue, info) => {
console.log("onSelect", info);
setSelectedKeys(selectedKeysValue);
};
React.useEffect(() => {
const checked = [];
treeData.forEach((data) => {
data.children.forEach((item) => {
if (item.checked) {
checked.push(item.key);
}
});
});
setCheckedKeys(checked);
}, []);
React.useEffect(() => {
if (searchValue) {
const filteredData = filteredTreeData(
treeData,
searchValue,
checkedKeys,
setExpandedKeys
);
setTree([...filteredData]);
} else {
setTree(treeData);
// setExpandedKeys([]);
}
}, [searchValue, checkedKeys]);
return (
<div>
<Search
style={{ marginBottom: 8 }}
placeholder="Search"
onChange={(e) => {
setSearchValue(e.target.value);
}}
/>
<Tree

Edited Response to fix uncheck issue
If I understood the question correctly, Is the issue with the fact that previous checked items are getting cleared on search and selection of new one?
I think the solution would be to use 2 different separate trees one for filtered and the other for normal.
Did some code changes on top of the sandbox code shared.
I have added a new tree when searchedValue is present.
On checking/unchecking the new filtered tree, the actual entire tree's checked values get updated
When the searched value is empty it would show the actual entire tree
Created a filteredKeys list to solve uncheck issue. Now I am able to select and unselect.
If you play around and refactor a bit, you should be able to achieve what you want.
Adding the same code below.

Let me know if this solves your issue. I am able to select multiple values in subsequent searches without loosing the checked ones.
As mentioned in the API document, filterTreeNode will keep keys from the tree node, and will not hide it.
filterTreeNode
Defines a function to filter treeNodes. When the function returns true, the corresponding treeNode will be checked
If you want to hide tree node, you will have to manually filter it first before before passing it to Tree in loop function, something like:
import React, { useState } from "react";

I have this dynamic checkbox, that I want to update the state with the selected options only ,I tried to add some checks to filter the state on change , but it seems I am not seeing what went wrong!
const checkBoxesOptions = [
{ id: 1, title: 'serviceOne' },
{ id: 2, title: 'serviceTwo' },
{ id: 3, title: 'serviceThree' },
];
const [selectedCheckBoxes, setSelectedCheckBoxes] = React.useState([]);
{checkBoxesOptions.map((checkBox, i) => (
<CheckBox
key={i}
label={checkBox.title}
value={1}
checked={false}
onChange={value => {
let p = {
title: checkBox.title,
isTrue: value,
};
if (p.isTrue) {
const tempstate = selectedCheckBoxes.filter(
checkbox => checkbox !== checkBox.title
);
console.log('temp state', tempstate);
setSelectedCheckBoxes([...selectedCheckBoxes, p.title]);
}
console.log(p);
}}
/>
))}
The value parameter is the event object.
(event) => {
const value = event.target.checked

How to add a class name in every row without effect the rest of the rows
import React, { useState } from 'react';
import './testEfect.css';
const Test = () => {
const arrayTest = [
{
name: '11',
id: '11'
},
{
name: '22',
id: '22'
},
{
name: '33',
id: '33'
},
]
const [state, setState] = useState(false);
const handleClick = (event) => {
const newState = event;
setState(state ? false : true);
}
return (
<div className="App">
{arrayTest.map((x, index) => {
return (
<ul key={index} className={state ? 'deletEfect' : ''}>
<li id={x.id} >
{x.name}
<button onClick={(event) => handleClick(x.id)}>Delete</button>
</li>
</ul>
)
})}
</div>
)
}
The problem here is that when you say the state is false; it is assuming the state is false for the whole component. It doesn't update the row but the whole component. So, at first, you need to add a deleted property that will take a different value for each row.
So,
const arrayTest = [
{
name: "11",
id: "11",
deleted: false
},
{
name: "22",
id: "22",
deleted: false
},
{
name: "33",
id: "33",
deleted: false
}
];
const [state, setState] = useState(arrayTest); //initial state
Now, when you render, you don't need to use that arrayTest. But you need to use the state. We won't touch arrayTest ever again. So we use,
{state.map((x, index) => {
return (
<ul key={index} className={x.deleted ? "testEfect" : ""}>
<li id={x.id}>
{x.name}
<button onClick={(event) => handleClick(x.id)}>Delete</button>
</li>
</ul>
);
})}
Notice we use state.map. We also send x.id to handleClick function.
Why? Because we will use that id to change the deleted value of the object. So our handleClick becomes,
const handleClick = (id) => {
const newState = state.map((element) => {
if (element.id === id)
return Object.assign({}, element, {
deleted: element.deleted ? false : true
});
return element;
});
setState(newState);
};
This is just updating the state in an immutable way.
Here is the full codesandbox for your convenience.
I have a very simple example about useTransition, my expectation is whenever i click on the shuffle button, the items below swap around by a smooth animation. But i doesn't work, the item does swapping but also the pos property. I think my understand about key in useTransition has something wrong, but i can't find it.
my current code: https://codesandbox.io/s/wonderful-solomon-c0sve?file=/src/index.jsx
what im trying to do is something like this
function App() {
const [items, setState] = useState([
{ name: 'C' },
{ name: 'D' },
{ name: 'E' },
{ name: 'F' },
{ name: 'G' },
{ name: 'A' },
{ name: 'B' },
]);
let index = -1;
const gridItems = items.map((item) => {
index += 1;
return { ...item, pos: index * 60 };
});
const transitions = useTransition(gridItems, item => item.name, {
from: () => ({ pos: -100 }),
enter: ({ pos }) => ({ pos }),
udpate: ({ pos }) => ({ pos }),
leave: () => ({ pos: -100 }),
});
return (
<div>
This is app<br/>
<button onClick={ () => setState(Lodash.shuffle) }>shuffle</button><br/><br/>
<div>
{transitions.map(({ item, props, key }) => {
return (
<animated.div
key={key}
className="item"
style={{ transform: props.pos.interpolate(pos => `translateY(${pos}px)`) }}
>
{`${item.name}`}
</animated.div>
)
})}
</div>
</div>
)
}
It was an age to figuring it out. You made a typo.
Try with this one:
update: ({ pos }) => ({ pos }),
In state, I have an array of list objects and would like to toggle the displayAddTaskForm. Every time I set state, the list that gets clicked gets rearranged and moves to the front of the lists on the UI. I believe I know why this is happening, just not sure of the solution. When I setState in toggleAddTaskForm, toggledList is first and then the other lists. How do I update the toggledList without changing the order of the lists. Here is the code.
this.state = {
lists: [
{
id: 1,
header: "To Do",
displayAddTaskForm: false,
},
{
id: 2,
header: "Working on It",
displayAddTaskForm: false,
},
{
id: 3,
header: "Taken Care Of",
displayAddTaskForm: false,
}
],
toggleAddTaskForm: (list) => {
const toggledList = {...list, displayAddTaskForm: !list.displayAddTaskForm}
const otherLists = this.state.lists.filter(l => l.id !== list.id)
this.setState({
lists: [toggledList, ...otherLists]
})
},
}
Putting function in the state is not a common thing. I think you need to seperate that function from state.
You can easily toggle items using Array.map() and checking the clicked item id with the item id. This will not change the order of items.
You can use the following code to toggle only one item:
class App extends Component {
constructor() {
super();
this.state = {
lists: [
{
id: 1,
header: "To Do",
displayAddTaskForm: false
},
{
id: 2,
header: "Working on It",
displayAddTaskForm: false
},
{
id: 3,
header: "Taken Care Of",
displayAddTaskForm: false
}
]
};
}
handleClick = id => {
let newList = this.state.lists.map(item => {
if (item.id === id) {
return {
...item,
displayAddTaskForm: !item.displayAddTaskForm
};
} else {
return {
...item,
displayAddTaskForm: false
};
}
});
this.setState({ lists: newList });
};
render() {
return (
<div>
<ul>
{this.state.lists.map(({ id, header, displayAddTaskForm }) => {
return (
<li key={id} onClick={() => this.handleClick(id)}>
{header} - Toggle Value: {displayAddTaskForm ? "true" : "false"}
</li>
);
})}
</ul>
</div>
);
}
}
Playground
Or if you want to be able to toggle every item, you can change the handleClick function like this:
handleClick = id => {
let newList = this.state.lists.map(item => {
if (item.id === id) {
return {
...item,
displayAddTaskForm: !item.displayAddTaskForm
};
} else {
return {
...item
};
}
});
this.setState({ lists: newList });
};
Playground
You could find the index of the list, copy the lists, and insert the modified list into the new lists array at the same index.
toggleAddTaskForm: (list) => {
const toggledList = {...list, displayAddTaskForm: !list.displayAddTaskForm}
const newLists = [...this.state.lists];
newLists[this.state.lists.indexOf(list)] = toggledList;
this.setState({
lists: newLists
})
}
This might help.
lists = [{
id: 1,
header: "To Do",
displayAddTaskForm: false,
}, {
id: 2,
header: "Working on It",
displayAddTaskForm: false,
}, {
id: 3,
header: "Taken Care Of",
displayAddTaskForm: false,
}]
const toggle = (list)=>{
const toggledList = {
...list,
displayAddTaskForm: true
}
const indexOfList = lists.findIndex(({id}) => id === list.id)
const newLists = [...lists]
newLists[indexOfList] = toggledList
setState({
lists: newLists
})
}
const setState = (o) => console.log(o)
toggle(lists[1])
