Getting content of currently active Text component wrapped inside popover of antd

I am using antd components for my react app. I have a Text component wrapped inside of Popover component. Now in my case this Popover is applied to one particular column of table, i.e. every row-element in that column has a Popover component rendered for it upon mouse hovering.
title: "Name",
dataIndex: "name",
key: "name-key",
sortType: "string",
sortDirections: ["descend", "ascend"],
sorter: (a, b) => a.name.length - b.name.length,
render: (text, record) => (
<Popover>
<Text onMouseOver={handleOnMouseOverCommitId}> {name} </Text>
</Popover>
)
I want to get hold of the row-element's value, the one contained by the above Text component whenever I hover over it. In this case the value denoted by {name} above.
I tried getting it with e.target.value via onMouseOver event, but it returned undefined.
I think I get the reason behind it, because the event.target returns an html node of type <span>.
With a normal div element e.target.value has worked in the past for me. But doing the same thing with a predefined component like antd's Text seems a bit trickier.
Just to elaborate, the Popover has two buttons and based on which button user clicks, I need to render some other components, something like an overlay component.
But in order to do that I would also need to get hold of the text value which originally triggered the Popover.
Below is the code(most of the things removed for preciseness).
record.name is what I ultimately need to capture.
<Popover
content={
<>
<Space>
<Button onClick={showSomeOverlayPaneForName}>
{"View Details for record.name"}
</Button>
<Button href={"https://abc.xyz.com/" + record.role}>
{"View Role Details"}
</Button>
</Space>
</>
}
trigger={"hover"}
>
<Text style={{"color": blue.primary}} copyable={true} onMouseOver={handleOnMouseOverName}>{record.name}</Text>
</Popover>
The handleOnMouseOverName function(which doesn't work anyway) :
const handleOnMouseOverName = (e) => {
//console.log("e.target.value :--- ", e.target.value);
setCurrentActiveName(e.target.value)
}
And once my currentActiveName variable is set(via useState), I use that value inside my function showSomeOverlayPaneForName
const showSomeOverlayPaneForName = (e) => {
axios
.get(
`some-url`,
{
params: {name: currentActiveName}
}
)
.then((response) => {
setData(response.data);
}).catch(reason => {
//xyz
});
}

You need to pass on the record of the enclosing render function to the handleOnMouseOverName function.
Check the following example
import React from 'react';
import 'antd/dist/antd.css';
import './index.css';
import { Space, Table, Button, Popover } from 'antd';
const App = () => {
const data = [
{
key: '1',
name: 'John Brown',
address: 'New York No. 1 Lake Park',
role: 'admin',
},
{
key: '2',
name: 'Jim Green',
address: 'London No. 1 Lake Park',
role: 'user',
},
{
key: '3',
name: 'Joe Black',
address: 'Sidney No. 1 Lake Park',
role: 'manager',
},
];
const columns = [
{
title: 'Name',
dataIndex: 'name',
key: 'name',
render: (name, record) => {
const content = (
<>
<Space>
<Button
onClick={() => {
viewDetail(record);
}}
>
{'View Details for ' + record.name}
</Button>
<Button href={'https://abc.xyz.com/' + record.role}>
{'View Role Details'}
</Button>
</Space>
</>
);
return (
<>
<Popover content={content} title="Details">
<div
onMouseOver={() => {
handleOnMouseOverName(record);
}}
>
{name}
</div>
</Popover>
</>
);
},
},
{
title: 'Address',
dataIndex: 'address',
key: 'address',
},
];
const handleOnMouseOverName = (record) => {
console.log(record);
};
const viewDetail = (record) => {
console.log(record);
};
return <Table columns={columns} dataSource={data} />;
};
export default App;
Output:
I hope this helps.

From antd docs: https://ant.design/components/popover/#header
Apparently you're supposed to render the <Popover/> with a content={content}-prop
For example
const content = <div>Content to render under title</div>
const App = () => {
const value = "Text to hover";
return (
<Popover content={content} title="Title">
<Text>{value}</Text>
</Popover>
)
}

How to send a property from an array of object from a child component to the parent component?

I have App, that is the parent component and I have the Child component:
The Child component gets a props called items so it can be reused depending on the data. It the example there is data, data1 and data2.
The thing is that I want to set a cookie from the parent component, to set the cookie I need the property link from data2, but I am already mapping data2 in the Child component.
What can I do to obtain the value of the property link in the parent component to pass it as an arguement here:
<Child
onClick={() =>
handleUpdate('How can I obtain here the string from link of data2?')
}
items={data2}
/>
This is the whole example code:
import * as React from 'react';
import './style.css';
const data = [
{ title: 'hey', description: 'description' },
{ title: 'hey1', description: 'description' },
{ title: 'hey2', description: 'description' },
];
const data1 = [
{ title: 'hey', description: 'description' },
{ title: 'hey1', description: 'description' },
{ title: 'hey2', description: 'description' },
];
const data2 = [
{ title: 'hey', link: 'link/hey' },
{ title: 'hey1', link: 'link/he1' },
{ title: 'hey2', link: 'link/he2' },
];
export default function App() {
const [, setCookie] = useCookie('example');
const handleUpdate = (cookie) => {
setCookie(null);
setCookie(cookie);
};
return (
<div>
<h2>App - Parent</h2>
<Child items={data} />
<Child items={data1} />
<Child
onClick={() =>
handleUpdate('How can I obtain here the string from link of data2?')
}
items={data2}
/>
</div>
);
}
export function Child({ items }) {
return (
<div>
<h2>Child</h2>
<ul>
{items.map((item) => {
return (
<>
<p>{item.title}</p>
<a href={item.link}>Go to title</a>
</>
);
})}
</ul>
</div>
);
}
Thank you!

If you want to get the link from the Child component you can simply add a link parameter in the callback:
<Child
onClick={(link) => handleUpdate(link)}
items={data2}
/>
Then from the Child you just need to call the onClick prop:
export function Child({ items, onClick }) { // here make sure to add the prop while destructuring
<a href={item.link} onClick={() => onClick(item.link)}>Go to title</a>

The map method doesn't change the array that it is called on, it just returns a new array, do the items array doesn't get affected at all here, so you can just call it normally like so:
return (
<div>
<h2>App - Parent</h2>
<Child items={data} />
<Child items={data1} />
<Child
onClick={() =>
handleUpdate(data2[0].link)
}
items={data2}
/>
</div>
);
Also, your Child component needs to accept the onClick function as a prop like so:
export function Child({ items, handleClick }) {
return (
<div onClick={handleClick}>
<h2>Child</h2>
<ul>
{items.map((item) => {
return (
<>
<p>{item.title}</p>
<a href={item.link}>Go to title</a>
</>
);
})}
</ul>
</div>
);
}

React MUI Multiple Select with Checkboxes not Check marking Initial Selected Options

I am still new in React and MUI, so please spare my life. I am learning to build Multiple Select Options with Checkboxes and I have populated the Dropdown Options from an Array.
I also have set up the initial/default state options. The initial/default state options (Nintendo & XBoX) are showing up in the main Input Select Field but unfortunately not being checked marked in the Dropdown Checkboxes, such as in the screenshot below.
Screenshot 1
What I'm trying to achieve is to be like this (all the selected options (Nintendo & XBoX) from the default state is showing on the checkboxes at initial page load):
Screenshot 2
This is my Live Demo coding in https://stackblitz.com/edit/react-rahqrq?file=demo.js
I'm confused, I can tick all the other option checkboxes in the dropdown except the default Initial Options from the State. It's unclickable and unchangeable, I have no idea why. Any tips and clues are greatly appreciated, Thanks in advance, please pardon my poor Grammar and Best Regards.

You need to findIndex of each item in the initial list to make them checked.
Try like below
{
variants.map(variant => (
<MenuItem key={variant.id} value={variant}>
<Checkbox
checked={
variantName.findIndex(item => item.id === variant.id) >= 0
}
/>
<ListItemText primary={variant.name} />
</MenuItem>
));
}

How to clear Multiselect Dropdown in Semantic UI React using a button?

I have a Semantic UI React Multiselect Dropdown inside a React functional component and want to have buttons inside the menu, as such (still need to center them...)
How can I clear the selected values using the 'Clear' button?
I am able to clear the selection using the 'x' icon, but that's built into the component.
<Dropdown
search
multiple
selection
clearable
closeOnSelectionChange={false}
options={filterInitialSuggestions()}
className='selectDropdown'
header={dropdownButtons()}
/>
const dropdownButtons = () => {
return (
<div>
<Button positive size='mini'>
Save
</Button>
<Button grey size='mini' onClick={() => console.log('I want to reset the multi select dropdown')}>
Clear
</Button>
<Divider />
</div>
);
};

'Save' and 'Clear' buttons with React useState(). In Reactjs you don't need to use DOM queryselector.
https://codesandbox.io/s/white-leftpad-q6re3?file=/src/Fun.jsx

import React, { Component } from 'react';
import { Dropdown } from 'semantic-ui-react';
const options = [
{ key: 1, text: 'Choice 1', value: 1 },
{ key: 2, text: 'Choice 2', value: 2 },
{ key: 3, text: 'Choice 3', value: 3 },
{ key: 4, text: 'Choice 4', value: 4 },
{ key: 5, text: 'Choice 5', value: 5 },
{ key: 6, text: 'Choice 6', value: 6 },
]
class Example extends Component {
state = {
dropval: []
}
onDropChange = (e, { value }) => {
this.setState(
(prevState) => { return { ...prevState, dropval: value } },
// () => console.log(this.state)
)
}
render() {
return (
<div>
<Dropdown
search
multiple
selection
clearable
closeOnSelectionChange={false}
options={options}
className='selectDropdown'
onChange={this.onDropChange}
value={this.state.dropval}
style={{ width: 300 }}
/>
</div>
);
}
}
export default Example;

I figured out how to solve this issue. I'm not sure if this is the best way, but it seems to work decently.
const dropdownButtons = () => {
return (
<>
<div className='dropdown-saveButton'>
<Button
positive
size='mini'
onClick={() => {
saveValues();
}}
>
Save
</Button>
<Button size='mini' onClick={clearDropdown}>
Clear
</Button>
</div>
<Divider inverted />
</>
);
};
const clearDropdown = e => {
var element = dropdownRef.current.querySelector('[aria-selected="true"]');
if (element) {
dropdownRef.current.querySelector('.clear')?.click();
}
};
<Dropdown
multiple
selection
fluid
clearable
header={dropdownButtons} />

Expand/Collapse all data

I am making a Accordion and when we click each individual item then its opening or closing well.
Now I have implemented expand all or collapse all option to that to make all the accordions expand/collapse.
Accordion.js
const accordionArray = [
{ heading: "Heading 1", text: "Text for Heading 1" },
{ heading: "Heading 2", text: "Text for Heading 2" },
{ heading: "Heading 3", text: "Text for Heading 3" }
];
.
.
.
{accordionArray.map((item, index) => (
<div key={index}>
<Accordion>
<Heading>
<div className="heading-box">
<h1 className="heading">{item.heading}</h1>
</div>
</Heading>
<Text expandAll={expandAll}>
<p className="text">{item.text}</p>
</Text>
</Accordion>
</div>
))}
And text.js is a file where I am making the action to open any particular content of the accordion and the code as follows,
import React from "react";
class Text extends React.Component {
render() {
return (
<div style={{ ...this.props.style }}>
{this.props.expandAll ? (
<div className={`content open`}>
{this.props.render && this.props.render(this.props.text)}
</div>
) : (
<div className={`content ${this.props.text ? "open" : ""}`}>
{this.props.text ? this.props.children : ""}
{this.props.text
? this.props.render && this.props.render(this.props.text)
: ""}
</div>
)}
</div>
);
}
}
export default Text;
Here via this.props.expandAll I am getting the value whether the expandAll is true or false. If it is true then all accordion will get the class className={`content open`} so all will gets opened.
Problem:
The open class is applied but the inside text content is not rendered.
So this line doesn't work,
{this.props.render && this.props.render(this.props.text)}
Requirement:
If expand all/collapse all button is clicked then all the accordions should gets opened/closed respectively.
This should work irrespective of previously opened/closed accordion.. So if Expand all then it should open all the accordion or else needs to close all accordion even though it was opened/closed previously.
Links:
This is the link of the file https://codesandbox.io/s/react-accordion-forked-sm5fw?file=/src/GetAccordion.js where the props are actually gets passed down.
Edit:
If I use {this.props.children} then every accordion gets opened.. No issues.
But if I open any accordion manually on click over particular item then If i click expand all then its expanded(expected) but If I click back Collapse all option then not all the accordions are closed.. The ones which we opened previously are still in open state.. But expected behavior here is that everything should gets closed.

In your file text.js
at line number 9. please replace the previous code by:
{this.props.children}
Tried in the sandbox and worked for me.
///
cant add a comment so editing the answer itself.
Accordian.js contains your hook expandAll and the heading boolean is already happening GetAccordian.js.
I suggest moving the expand all to GetAccordian.js so that you can control both values.

in this case this.props.render is not a function and this.props.text is undefined, try replacing this line
<div className={`content open`}>
{this.props.render && this.props.render(this.props.text)}
</div>
by this:
<div className={`content open`}>
{this.props.children}
</div>
EDIT: //
Other solution is to pass the expandAll property to the Accordion component
<Accordion expandAll={expandAll}>
<Heading>
<div className="heading-box">
<h1 className="heading">{item.heading}</h1>
</div>
</Heading>
<Text>
<p className="text">{item.text}</p>
</Text>
</Accordion>
then in getAccordion.js
onShow = (i) => {
this.setState({
active: this.props.expandAll ? -1: i,
reserve: this.props.expandAll ? -1: i
});
if (this.state.reserve === i) {
this.setState({
active: -1,
reserve: -1
});
}
};
render() {
const children = React.Children.map(this.props.children, (child, i) => {
return React.cloneElement(child, {
heading: this.props.expandAll || this.state.active === i,
text: this.props.expandAll || this.state.active + stage === i,
onShow: () => this.onShow(i)
});
});
return <div className="accordion">{children}</div>;
}
};

Building off of #lissettdm answer, it's not clear to me why getAccordion and accordion are two separate entities. You might have a very valid reason for the separation, but the fact that the two components' states are interdependent hints that they might be better implemented as one component.
Accordion now controls the state of it's children directly, as before, but without using getAccordion. Toggling expandAll now resets the states of the individual items as well.
const NormalAccordion = () => {
const accordionArray = [ //... your data ];
const [state, setState] = useState({
expandAll: false,
...accordionArray.map(item => false),
});
const handleExpandAll = () => {
setState((prevState) => ({
expandAll: !prevState.expandAll,
...accordionArray.map(item => !prevState.expandAll),
}));
};
const handleTextExpand = (id) => {
setState((prevState) => ({
...prevState,
[id]: !prevState[id]
}));
};
return (
<>
<div className="w-full text-right">
<button onClick={handleExpandAll}>
{state.expandAll ? `Collapse All` : `Expand All`}
</button>
</div>
<br />
{accordionArray.map((item, index) => (
<div key={index}>
<div className="accordion">
<Heading handleTextExpand={handleTextExpand} id={index}>
<div className="heading-box">
<h1 className="heading">{item.heading}</h1>
</div>
</Heading>
<Text shouldExpand={state[index]}>
<p className="text">{item.text}</p>
</Text>
</div>
</div>
))}
</>
);
};
Heading passes back the index so the parent component knows which item to turn off.
class Heading extends React.Component {
handleExpand = () => {
this.props.handleTextExpand(this.props.id);
};
render() {
return (
<div
style={ //... your styles}
onClick={this.handleExpand}
>
{this.props.children}
</div>
);
}
}
Text only cares about one prop to determine if it should display the expand content.
class Text extends React.Component {
render() {
return (
<div style={{ ...this.props.style }}>
<div
className={`content ${this.props.shouldExpand ? "open" : ""}`}
>
{this.props.shouldExpand ? this.props.children : ""}
</div>
</div>
);
}
}
