Updating parent block attributes from child block?

I can't seem to find an answer to this that I can understand
I have tabs and a tab block, which is a clone of this basic tab block plugin. I'm trying to add the ability to select an "icon" for each tab block.
I'm close. Using the MediaUpload component, I'm able to see the file I've selected under the activeTab object, but it doesn't update the parent block attribute, so I can't reference the icon_url attribute.
tab/edit.js
const Edit = ({ attributes, setAttributes, clientId }) => {
const { uid, activeTab } = attributes;
useEffect(() => {
if (!uid) {
setAttributes({ uid: clientId });
}
}, []);
const display = activeTab === uid ? "block" : "none";
const ALLOWED_MEDIA_TYPES = ["image", "svg"];
const setTabIcon = (icon_url) => {
const parentBlock = select("core/block-editor").getBlock(clientId);
dispatch("core/block-editor").updateBlockAttributes(
parentBlock.clientId,
{
...attributes,
icon_url,
}
);
};
return (
<div {...useBlockProps()}>
<InspectorControls>
<div>
<MediaUpload
allowedTypes={ALLOWED_MEDIA_TYPES}
onSelect={(media) => setTabIcon(media.url)}
render={({ open }) => (
<button onClick={open}>Open Media Library</button>
)}
/>
</div>
</InspectorControls>
<div className={"guten-tab-panel"} style={{ display }}>
<InnerBlocks
allowedBlocks={["core/heading", "core/paragraph"]}
renderAppender={() => <InnerBlocks.ButtonBlockAppender />}
/>
</div>
</div>
);
};
export default Edit;
I would first think that using setAttributes here would also update the parent, but this only updates setActive in the child block. It doesn't keep the change.
In tabs.js, I'm trying to reference tab.icon_url. icon_url doesn't exist, only uid and title
tabs/tabs.js
const Edit = ({ attributes, setAttributes, clientId }) => {
const { tabs, activeTab } = attributes;
const blockProps = useBlockProps({
className: `${useBlockProps().className} guten-tab-wrapper`,
});
const setActiveTab = (uid) => {
setAttributes({ activeTab: uid });
const parentBlock = select("core/block-editor").getBlock(clientId);
parentBlock.innerBlocks.forEach((innerBlock) => {
dispatch("core/block-editor").updateBlockAttributes(
innerBlock.clientId,
{
activeTab: uid,
}
);
});
};
const addNewTab = () => {
const tab = createBlock("ahsan03/tab");
const position = tabs.length;
dispatch("core/block-editor").insertBlock(tab, position, clientId);
setAttributes({
tabs: [
...tabs,
{
uid: tab.clientId,
title: `Tab ${tabs.length + 1}`,
icon_url: "",
},
],
});
setActiveTab(tab.clientId);
};
const tabTitleChange = (newValue) => {
setAttributes({
tabs: [
...tabs.map((tab) => {
return tab.uid === activeTab
? {
...tab,
title: newValue,
}
: tab;
}),
],
});
};
useEffect(() => {
if (tabs.length && !activeTab) {
setActiveTab(tabs[0].uid);
}
}, [tabs]);
return (
<>
<div {...blockProps}>
<div className={"guten-tabs-nav"}>
{tabs.map((tab) => {
return (
<div
key={tab.uid}
className={"guten-tab-item"}
role="tab"
tabIndex="0"
onClick={() => setActiveTab(tab.uid)}
>
<div
className={`guten-tab-link${
tab.uid === activeTab
? " is-active"
: ""
}`}
>
<img src={tab.icon_url} alt="" />
{console.log("tabs tab", {
tab,
})}
<RichText
tagName="div"
value={tab.title}
onChange={tabTitleChange}
/>
</div>
</div>
);
})}
<Button
variant={"primary"}
icon={"plus"}
onClick={addNewTab}
>
{__("", "gtt")}
</Button>
</div>
<div className={"guten-tab-content"}>
<InnerBlocks
allowedBlocks={["ahsan03/tab"]}
renderAppender={false}
/>
</div>
</div>
</>
);
};
export default Edit;
How can I fix this so uploading an image is in the parent block attributes?
Here's an updated setTabIcon function that I think is closer to what I need, I'm just not sure what to do after fetching the parentBlock.
const setTabIcon = (icon_url) => {
const parentBlockIds =
select("core/block-editor").getBlockParents(clientId);
parentBlockIds.forEach((parentBlockId) => {
const parentBlock = select("core/block-editor").getBlock(parentBlockId);
console.log({ parentBlock });
});
};

Make a state variable in the parent component, and then pass that state and setState to the child as props, and then from the child component, you can update the state in the parent component.

I was able to fix this by moving setTabIcon and the MediaFile component to the parent block.
Would love suggestions on how to improve this code.

ReactJS rendering issue with edited array

Why does ReactJS remove the last element when the array is different after removing the middle element when using array.splice?
This is my code. I am using React-Redux.
const reducerNotesAndLogin = (state = initialState, action) => {
var tableNotes = "notities";
var tableCategories = "categories";
switch(action.type){
case "CATEGORY_REMOVE":
// Remove the category
var newCategories = state.categories;
console.log("state.categories", state.categories);
console.log("before: ", {newCategories});
var index = 0;
for(var i = 0; i < newCategories.length; i++){
if(newCategories[i].id === action.payload.categoryId){
newCategories.splice(i, 1);
index = i;
i--;
}
}
console.log("after: ", {newCategories});
state = {
...state,
categories: newCategories
}
break;
default:
break;
}
return state;
}
export default reducerNotesAndLogin;
Output below (I deleted the middle element. My web app always removes the last element of the categories (but not from the array).
Step 1: Initial state
Step 2: Remove middle item, expecting the middle item to be removed.
Step 3: Confusion
Why is the array correct, but the view incorrect? I am updating the state.categories correctly right?
This is my render code (as is - without filtering away any other code that mihgt be important)

import React from 'react';
import { connect } from 'react-redux';

I think it has something to do with the rendering. Because the arrays are correct when I console.log them. Only the view is different...

Do not modify the state in reducer directly. Create a copy of state value and then modify it.
Change:
var newCategories = state.categories;
To:
var newCategories = [...state.categories];
You should not modify the same array while looping through it.
for (var i = 0; i < newCategories.length; i++) {
if (newCategories[i].id === action.payload.categoryId) {
newCategories.splice(i, 1);
index = i;
i--;
}
}

I got the answer after looking through it with a friend of mine. The solution is pretty simple...
Lesson 101: Make sure that you have a unique "key" property when looping through an array in your UI.
The solution is to add this to my code:
<div key={category.id}>
{this.props.categories.map....
...
</div>

React JS removeEventListener not firing

I have two functions with one containing addEventListener("click") and the other to remove
show() {
console.log("SHOW FUNCTION")
this.setState({
listVisible: true
})
document.addEventListener("click", this.hide.bind(this));
}
hide() {
console.log("HIDE FUNCTION")
this.setState({
listVisible: false
})
document.removeEventListener("click", this.hide.bind(this));
}
On initial click, show() is fired, state is updated as expected and once the second click is made hide() is fired and all is well.
When I click again ( third click ) my console.logs list show() first and then two logs for hide() thus setting my state back to false when it should be true, just like the first sequence.
I'm unsure as to why this is happening, it's almost as if the removeEventListener isn't firing. Could also be wrong context of "this"?
Here is my component code:
renderListItems() {
const items = [];
for (var i = 0; i < this.props.list.length; i++) {
const item = this.props.list[i];
items.push(<div className="option" onClick={() => this.select(item)}>
<span>{item.name}</span>
<i className="fa fa-check"></i>
</div>);
}
return items;
}
render() {
console.log("give me", this.state.listVisible)
return (
<div className={"dropdown-container" + (this.state.listVisible ? " show" : "")}>
<div className={"dropdown-display" + (this.state.listVisible ? " clicked": "")} onClick={() => this.show()}>
<span>
{this.state.selected.name}
</span>
<i className="fa fa-angle-down"></i>
</div>
<div className="dropdown-list">
<div>
{this.renderListItems()}
</div>
</div>
</div>
)
}

Every time you call .bind it is creating a new function. You should create the bound function once when the component is created so that the removeEventListener can find the function.
You can bind class methods in ES6:
hide = () => {
}
Or do it in your constructor:
constructor(...args) {
super(...args);
this.hide = this.hide.bind(this);
}
Then your event listener can simply refer to the already bound function this.hide.

I found a solution - to remove the hide function, remove all binds and update state within the select function.
import React, {Component} from 'react'
import classNames from 'classnames';
import './style.scss'
export default class FormCustomSelect extends Component {
constructor(props) {
super(props);
this.state = {
listVisible: false,
display: "",
selected: this.props.selected
}
}
select(item) {
this.setState({
selected: item,
listVisible: false
})
}
show() {
this.setState({
listVisible: true
})
}
renderListItems() {
const items = [];
for (var i = 0; i < this.props.list.length; i++) {
const item = this.props.list[i];
items.push(<div className="option" onClick={() => this.select(item)}>
<span>{item.name}</span>
<i className="fa fa-check"></i>
</div>);
}
return items;
}
render() {
console.log("give me", this.state.listVisible)
return (
<div className={"dropdown-container" + (this.state.listVisible ? " show" : "")}>
<div className={"dropdown-display" + (this.state.listVisible ? " clicked": "")} onClick={() => this.show()}>
<span>
{this.state.selected.name}
</span>
<i className="fa fa-angle-down"></i>
</div>
<div className="dropdown-list">
<div>
{this.renderListItems()}
</div>
</div>
</div>
)
}
}

React & Redux: "form submission canceled because the form is not connected"

I am still new in React and Redux. So, I know the existence of redux-form, but Im not intend to use in this project. So, what I am doing is creating a form without using redux-form. This form will grab the data from the reducers and pass it to backend API.
This is my main CreateListing.jsx page.
// #flow
import React from 'react';
import { connect } from 'react-redux';
import { Helmet } from 'react-helmet';
import { SEOService } from '[services]';
import CreateListingFormPage1 from './CreateListing/CreateListingFormPage1';
import CreateListingFormPage2 from './CreateListing/CreateListingFormPage2';
import CreateListingFormPage3 from './CreateListing/CreateListingFormPage3';
import WhereAmI from './CreateListing/WhereAmI';
import SuccessCreateListing from './CreateListing/SuccessCreateListing';
type Props = {
...props...
};
class CreateListing extends React.Component<Props> {
getPageBySequence(pagenum) {
// depending on whether User is logged in or not, show/hide the Login/Signup form which is Page3
let sequence = [ CreateListingFormPage1, CreateListingFormPage2, CreateListingFormPage3 ];
if (this.props.isLoggedIn) {
sequence = [ CreateListingFormPage1, CreateListingFormPage2, CreateListingFormPage2 ];
}
return sequence[pagenum-1];
}
getSubmitCreateListing = (e) => {
e.preventDefault();
const propertyType = this.props.listingType;
const propertyName = this.props.suggestedBuildings.selected;
const propertyBuildingType = this.props.propertyBuildingType;
const bedrooms = this.props.bed;
const bathrooms = this.props.bath;
const price = this.props.price;
const builtUp = this.props.builtUp;
const title = this.props.title;
const tenure = this.props.tenure;
const description = this.props.description;
/* IN CASE USER NOT YET LOGGGED IN */
if(this.props.isLoggedIn === false) {
const email = this.props.email;
const password = this.props.password;
this.props.cacheCreateListing({ email, password, propertyType, propertyName, propertyBuildingType, bedrooms, bathrooms, price, builtUp, title, tenure, description });
}
this.props.cacheCreateListing({ propertyType, propertyName, propertyBuildingType, bedrooms, bathrooms, price, builtUp, title, tenure, description });
if(CreateListingFormPage1.landedTypes.includes(propertyBuildingType)) {
this.props.geocodingRequired(true);
}

}

}
render() {
if(this.props.isListingCreated){
return <SuccessCreateListing />;
}
else if(this.props.isListingLoading){
return <div className="create-listing-spinner" />
}
const CurrentPage = this.getPageBySequence(this.props.formCurrentPage);
return (

onLoadingCreateListing: () => dispatch({type: 'CREATE_LISTING_LOADING'}),

export default connect(MapStateToProps,MapDispatchToProps)(CreateListing);
So, my <input type="text" /> are all from CreateListingFormPage1, CreateListingFormPage2 and CreateListingFormPage3 and put together in <CurrentPage />. My <form onSubmit={...}></form> is in this CreateListing.jsx page. Im not whether it is allowed to do it like this.
So, when I click submit, I got warning of Form submission canceled because the form is not connected.
My example of <input type="" /> in CreateListingFormPage1 are:

};
const MapStateToProps = (state: State) => ({

const MapDispatchToProps = (dispatch: Dispatch) => ({

export default connect(MapStateToProps, MapDispatchToProps)(CreateListingFormPage2);
Basically, there is nothing wrong with my redux store. All the value of the input is captured successfully. The problem is when submitting the form, either the onSubmit or my form structure method is incorrect.
This is CreateListing.js reducer should it be helpful:
const INITIAL_STATE= {
isListingLoading: false,
isListingCreated: false,
}
const CreateListing = (state = INITIAL_STATE, action) => {
switch(action.type){
case 'CREATE_LISTING_LOADING':
return Object.assign({}, state, {isListingLoading: true});
case 'CREATE_LISTING_SUBMIT_FORM':
return Object.assign({}, state, {isListingCreated: true});
default:
return state;
} }
export default CreateListing;
Any help is much appreciated.

if you have any other buttons in your form you should add type="button".
so make changes like this.
<button type="button" className="Button button-create is-red" onClick={this.props.onLoadingCreateListing}>
CREATE LISTING
</button>

Set state for only for self data into map on reactjs

JSfiddle: Here
The issue is how can you see is, when i click on the button to set the state for edit or remove option, this will show the view for all the items,
and should be only the view that is clicked, i know the state change to true and is the same for all the items but i don't know how to set the state only for one entry any idea?
Thank you in advance.

Your problem is that the edit/remove state is singular and for the entire list. Each item in the list receives the same state here:
if (edit) {
return (
<div>
<span>Edit view</span>
<br/>
<button onClick={cancelEdit}>Cancel</button>
</div>
)
}
The single edit variable from the state is applied to each list item. If you want to individually set the edit state for each item, it will need to be kept track of with that item.
EX:
const users = [
{
id: 1,
name: 'User1',
edit: true
}]
This way each individual item will be able to tell what state it is in individually. User1 item will have an edit mode that is independent of the other users.
Then you can render something like this:
return users.map((user) => {
return (
<ul key={user.id}>
<li>
<div>
<span ref='span'>{user.name}</span>
<br/>
{user.edit ? 'EDIT MODE' : 'NOT EDIT MODE'}
</div>
</li>
</ul>
)
})
