How to implement two search terms in React? The first search term is name from the api, the second search term is the element's grandChild's innerHTML (the grandchild is an array of elements). The user should be able to filter the search by the two search terms together or individually.
The students array looks like this
[
{city: "NY"
email: "lily#hotmail.com"
firstName: "Lily",
lastName: "Yee",},
...
]
For each student, I have the functionality to add tags to them. The tags that are added to each student are html buttons. I have the function to search students by their names. I also need to implement a functionality to search students by those html buttons.

I'm not entirely sure what are you asking. If you are simply asking how to filter an array of students with tag(s) and name, and you already know the UI part. This is how you may do it.
Since you never mention what your students array look like, I would assume the following:
[
{
"firstName": "",
"lastName": "",
"tags": [
"tag1",
"tag2"
]
}
]
const [searchByName, setSearchByName] = useState("");
const [searchByTags, setSearchByTags] = useState([]); // I don't think it is a good idea to let people to search by one and only one tag, I changed it multiple tags
const [students, setStudents] = useState([]); // all avalible students
// this is the list of student you should display in the search result
const filteredStudents = useMemo(() => students.filter(({ firstName, lastName, tags}) =>
searchByName === "" || (firstName + " " + lastName).includes(searchByName) // include this student if the search string is empty or the full name includes the search string
&& tags.length === 0 || searchByTags.every(tag => tags.includes(tag)) // and if the search tags are empty or student matches all the search tags
), [students, searchByName, searchByTags]);

I am a beginner in react js programming. I'm trying to do the todo project, which is a classic project. When I delete or add an element from the list, the newly formed list appears on the screen by combining with the previous one, I will show it with a picture below. I did not understand the source of the eror so wanted to post it here to get some advices suggestions about why it is happening.Thank you.(I am getting and storing data in firebase firestore database)
Before Adding an element initial array state
After adding an element to the array.
I am using useState for array and using useEffect to get initial data
MainPage.js that contains form and the list components.
const MainPage = () => {

const [array, setArray] = useState([]);
const sub = async (email) => {
var result = [];
await onSnapshot(doc(db, "users", email), (doc) => {

});
});
setArray(result);
setLoding(false);
});
};
useEffect(() => {
sub(auth.currentUser.email);
}, []);
const onAddToDo = (todoTitle) => {
setArray((prevAray) => {

});
};
export const addnewTodo = (title) => {

todos: arrayUnion({ title: title }),
});
};
TodoForm.js component
const ToDoForm = (props) => {
const [todoTitle, setTitle] = useState("");
const titleChangeHandler = (event) => {
setTitle(event.target.value);
};
const newTodoAdder = (event) => {
event.preventDefault();

SOLUTION
I fixed the issue by changing the add and remove functions that were inside of MainPage.js file You can see the new versions bellow. Hope someday it will help somebody.
Use effect was called once all I had to do get the data again after a change...
New Remove and Add functions
const onAddToDo = (todoTitle) => {
console.log(todoTitle + " Added");
sub(auth.currentUser.email);
};
const onRemove = (title) => {
console.log(title + " Deleted");
sub(auth.currentUser.email);
};
I have a list of students that will display onto the web browser depending on what you filter by name/tag. If those filter fields become empty, the page re-fetches all the students from an API and displays them.
The tags are stored in an array using useState for each Student object.
Example Problem: After adding a tag to a student, then somehow filtering the students, and then finally clearing the filter fields, all the students will be displayed again but WITHOUT their tags.
Expected Outcome: I need the student to keep their tags, at least for a current session on the website.
Question: How can I solve this? Should I use localStorage? or a Database such as MongoDB? or something else?

Since you are passing the students prop to the child component, any time the students change the component will be re-rendered. Also since the filter is in the parent component, the child component will re-render because you are calling fetchStudents() in the filter function. You can toy with changing how you filter the students.
Most tutorials I found on this subject were outdated. So here I am.
What I expect to do with this app is, input text into the field and filter the results based on what you input. Currently I'm stuck and I've been through so many array methods such as filter, indexOf etc. I'm sure I am overthinking the issue so I need help. Here's the code I have currently:
import React, { useState, useEffect } from "react";
import axios from "axios";
const ITEMS_API_URL = "https://restcountries.eu/rest/v2/all";
function Autocomplete() {
const [countryArr, setCountryArr] = useState([]);
useEffect(() => {
axios.get(ITEMS_API_URL).then((res) => {
setCountryArr(() => {
let arr = res.data;
arr.splice(10, arr.length);
return arr;
});
console.log(countryArr);
});
}, []);
const onChange = e => {
const inputValue = e.target.value
const filteredSuggestions = countryArr.find(arr => arr.name == inputValue)
setCountryArr(filteredSuggestions)
}
return (
<div className="wrapper">
<div className="control">
<input type="text" className="input" onChange={onChange} />
</div>
<div className="list is-hoverable" />
{countryArr.map((country) => {
return (
<ul key={country.numericCode}>
{country.name}
</ul>
)
})}
</div>
);
}
export default Autocomplete;
You should not change to actual data source (countryArr) otherwise it reset and store last filtered on that. so I create state variable filteredCountryArr for filter and setting up filtered valued on that.
import React, { useState, useEffect } from "react";
import axios from "axios";
const ITEMS_API_URL = "https://restcountries.eu/rest/v2/all";
function Autocomplete() {
const [countryArr, setCountryArr] = useState([]);
const [filteredCountryArr, setFilteredCountryArr] = useState([]);
useEffect(() => {
axios.get(ITEMS_API_URL).then(res => {
setCountryArr(() => {
let arr = res.data;
arr.splice(10, arr.length);
return arr;
});
console.log(countryArr);
});
}, []);
const onChange = e => {
const inputValue = e.target.value;
const filteredSuggestions = countryArr.find(arr => arr.name == inputValue);
setFilteredCountryArr(filteredSuggestions);
};
return (
<div className="wrapper">
<div className="control">
<input type="text" className="input" onChange={onChange} />
</div>
<div className="list is-hoverable" />
{filteredCountryArr && filteredCountryArr.length > 0 && filteredCountryArr.map(country => {
return <ul key={country.numericCode}>{country.name}</ul>;
})}
</div>
);
}
export default Autocomplete;
I have a list of users on the page.

You need to approach this differently.. where the array of tags are available at the top level component - rather than doing DOM manipulation. Move
const [tags, setTags] = useState([]);
Into the StudentsContainer, and pass it down through Students and Add Tag as props, then refactor your search to use tags.
I've added a code sandbox here, with a basic gist of how I'd approach it.
https://codesandbox.io/s/frosty-ishizaka-hui8j
Theres quite a bit going in this question so we should focus on simplifying the problem by removing everything that is of no concern.
So how do we only render those students who have the tag that we currently are searching for? By using Array.prototype.filter() before we map over students and return a <Student /> for each array item.
import React, { useState } from "react";
const data = [
{id:1,firstName:"Mickey",lastName:"Mouse",tags:[{id:1,label:"mouse"}]},
{id:2,firstName:"Donald",lastName:"Duck",tags:[{id:1,label:"duck"}]},
{id:3,firstName:"Minnie",lastName:"Mouse",tags:[{id:1,label:"mouse"},{id:2,label:"cool"}]}
];
const StudentsContainer = ({ students = data }) => {
const [searchByTagsValue, setSearchByTagsValue] = useState("");
return (
<>
<input
value={searchByTagsValue}
placeholder="Search by tag"
onChange={(e) => setSearchByTagsValue(e.target.value)}
/>
{students.length &&
students
.filter((student) => shouldStudentDisplay(student.tags, searchByTagsValue))
.map((student) => <Student key={student.id} student={student} />)}
</>
);
};
const Student = ({ student, style }) => (
<div style={style}>
<h5>
{student.firstName} {student.lastName}
</h5>
<Tags tags={student.tags} />
<hr />
</div>
);
const Tags = ({ tags }) => (
<ul>
{tags.map((tag) => (
<li key={tag.id}>{tag.label}</li>
))}
</ul>
);
const shouldStudentDisplay = (tags, searchByTagsValue) => {
if (!searchByTagsValue) {
return true;
}
return tags.findIndex(({ label }) => label === searchByTagsValue) !== -1;
};
export default StudentsContainer;
Once you can filter your data in place like above, you need an updater function in StudentsContainer that will take a student id, and a new tag name, and update (a localised version of) the students data.
Pass this updater function all the way from StudentsContainer down to Tags so it can update the data in the ancestor component (commonly referred to as prop drilling).
const [localStudents, setLocalStudents] = useState(students);
const onSubmitTag = (label, id) => {
const index = localStudents.findIndex((student) => student.id === id);
if (index !== -1) {
const newStudents = [...localStudents];
newStudents[index] = {
...newStudents[index],
tags: [...newStudents[index].tags, { id: Date.now(), label }]
};
setLocalStudents(newStudents);
}
};
As you can see, we aren't really searching through the HTML to hide and show things in an imperative way.
In react, we are encouraged to update the source data, and allow the rendered UI to react in a declarative way.
React makes it painless to create interactive UIs. Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes.
Declarative views make your code more predictable and easier to debug.
I want to filter over an array using react hooks. It should be a fairly straight forward task, but I am assuming it is something to do with hooks being updated asynchronously, although this could be wrong.
I am fairly stumped, but have included a code sandbox and my code below:
const teams_data = [
"tottenham",
"arsenal",
"man utd",
"liverpool",
"chelsea",
"west ham"
];
function App() {
const [teams, setTeams] = React.useState(teams_data);
const [search, setSearch] = React.useState("");
return (
<div className="App">
<input
onChange={e => {
const test = teams.filter(team => {
return team.toLowerCase().includes(e.target.value.toLowerCase());
});
console.log("test: ", test);
// uncomment line below and teams is logged as I want
setTeams(test);
setSearch(e.target.value);
}}
type="text"
value={search}
/>
{teams.map(team => (
<p>{team}</p>
))}
</div>
);
}
You need to filter the original data :
const test = teams_data.filter(team => {
return team.toLowerCase().includes(e.target.value.toLowerCase());
});
https://codesandbox.io/s/thirsty-austin-uqx8k
You just need to add another state for search results
const [data , setData] = useState(teams);
const [query, setQuery] = useState('')
const[res , setRes] = useState([]);
return (
<div className="App container">
<form onSubmit = {(e) => e.preventDefault()}>
<input type = "search" className = "srh" placeholder = "search about..."
onChange = {(e) => {
const test = data.filter(team => {
return (
team.toLowerCase().includes(e.target.value.toLowerCase())

I've made custom hook.
It receives the array as a first param
the search variable as a second
and the property you want to filter by
I hope it's helpfull
export function useSearch(array: any[], search: string, field: string) {
const filteredArray = array.filter((entry) => {
if (search === "") return entry;
else if (
entry[field].toLocaleLowerCase().includes(search.toLocaleLowerCase())
)
return entry;
});
return {
filteredArray
};
}
Them apply the filtered array to your map function
import { useSearch } from "./useSearch";
import { useState } from "react";
const array = [
{
id: 1,
name: "Humberto Guenzo Yoshimoto"
},
{
id: 2,
name: "Diego Braga"
},
{
id: 3,
name: "Hudson Teixeira"
},
{
id: 4,
name: "Matheus Doimo"
}
];
type FilteredArrayTypes = {
id: number;
name: string;
};
export default function App() {
const [searchByFullName, setSearchByFullName] = useState("");
const { filteredArray } = useSearch(array, searchByFullName, "name");
return (
<div className="App">
<h1>Search list</h1>
<input
onChange={(e) => setSearchByFullName(e.target.value)}
type="text"
value={searchByFullName}
placeholder="search"
/>
{filteredArray.map((entry: FilteredArrayTypes) => {
return (
<ul>
<li>{entry.name}</li>
</ul>
);
})}
</div>
);
}
Here goes a sandbox with the code: here
