I created app to map all card components on a page. But components are shown vertically. I need to show 3 components per row. How can I show it like that? Here is my code.
const[item, setItem] = useState([]);
function addItem(newItem){ //This addItem Part is working.
setItem(prevItems =>{
return [...prevItems, newItem]
});
}
return(<div className="container">
<div className="row">
<div className="col-lg-4" style={{cursor: "pointer"}}>
<AddCard />
</div>
<div style={{cursor: "pointer"}}>
{item.map((items, index)=>{
return(
<div className="col-lg-4" >
<ItemCard
key={index}
id={index}
title={items.title}
description={items.description}
/>
</div>
)
})}
</div>
</div>)
You can use display:"flex" on the container
const[item, setItem] = useState([]);
function addItem(newItem){ //This addItem Part is working.
setItem(prevItems =>{
return [...prevItems, newItem]
});
}
return(<div className="container">
<div className="row">
<div className="col-lg-4" style={{cursor: "pointer"}}>
<AddCard />
</div>
<div style={{cursor: "pointer", display:"flex"}}>
{item.map((items, index)=>{
return(
<div className="col-lg-4" >
<ItemCard
key={index}
id={index}
title={items.title}
description={items.description}
/>
</div>
)
})}
</div>
</div>)
Use flexboxes, as React lets you create components, so we can style them just like HTML elements with flexboxes.
Example :
.flexbox-container {
display: flex;
flex-direction: row;
}
<div class="flexbox-container">
<div>Element1</div>
<div>Element2</div>
<div>Element3</div>
</div>

I included an Icon while mapping an array and I need to change the icon on that specific iteration onclick, I also want to render the test results when the icon is clicked.
I'm not sure how to get a unique value that is specific to this iteration that will handle this change or is my structure all wrong?
** went to sleep found solution = encapsulation **
map the component so the boolean variable is local scoped to that iteration.
shared solution below
const Students = ({students}) => {
const [showTests, setShowTests] = useState(false);
return (
<div className="wrapper" key={student.id}>
<div className="img-container">
<img src={student.pic} alt="student" />
</div>
<div className="content">
<h1>
{student.firstName.toUpperCase()} {student.lastName.toUpperCase()}
</h1>
<p>Email: {student.email}</p>
<p>Company: {student.company}</p>
<p>Skill: {student.skill}</p>
<p>Average: {averageGrade(student.grades)}%</p>
{showTests && <TestResults results={student.tests} />}
</div>
{showTests ? (
<FontAwesomeIcon
onClick={() => setShowTests(!showTests)}
className="faIcon"
icon={faMinus}
/>
) : (
<FontAwesomeIcon
onClick={() => setShowTests(!showTests)}
className="faIcon"
icon={faPlus}
/>
)}
</div>
);
}
const Main = () => {
return (
<div className="main" id="main">
{filteredStudents.map(student => (
//each iteration is a unique component
<Students student={student} />
))}

Thanks ahead of time for any suggestions
The return must always have a top-level tag.
const Students = ({ students }) => {
return (
<>
{students.map((student, i) => (
<div className="wrapper" key={student.id}>
<div className="img-container">
<img src={student.pic} alt="student" />
</div>
<div className="content">
<h1>
{student.firstName.toUpperCase()}{" "}
{student.lastName.toUpperCase()}
</h1>
<p>Email: {student.email}</p>
<p>Company: {student.company}</p>
<p>Skill: {student.skill}</p>
<p>Average: {averageGrade(student.grades)}%</p>
{faMinus && <TestResults results={student.tests} />}
</div>
<FontAwesomeIcon
id={i}
onClick={(e) => handleTests(e.target.id)}
className="faIcon"
icon={current ? faPlus : faMinus}
/>
</div>
))}
</>
);
};
Let me know if this is what you're thinking. Just store the index in a state variable and compare against it. When they click change the index to the one they clicked on.
const Students = ({students}) => {
const [selectedIndex, setSelectedIndex] = useState(0)
function handleTests(id, index) { //NEW
//Your current code
setSelectedIndex(index) //NEW
}
return (
{students.map((student, i) => (
<div className="wrapper" key={student.id}>
<div className="img-container">
<img src={student.pic} alt="student" />
</div>
<div className="content">
<h1>
{student.firstName.toUpperCase()} {student.lastName.toUpperCase()}
</h1>
<p>Email: {student.email}</p>
<p>Company: {student.company}</p>
<p>Skill: {student.skill}</p>
<p>Average: {averageGrade(student.grades)}%</p>
{selectedIndex == i && <TestResults results={student.tests} />} //NEW
</div>
<FontAwesomeIcon
id={i}
onClick={e => handleTests(e.target.id, i)} //NEW
className="faIcon"
icon={selectedIndex == i ? faPlus : faMinus}
/>
</div>
))}
)
}
Basically, I have a nested component that I want to render with the parent component and it's working fine when the server starts.
But the problem arises when I switch back from another page. Some of the nested components get disappeared. If I made a refresh then again everything ok.
How can I solve this issue?
Normal:
Image-1
Component disappeared:
Image-2
Index.js:
import BannerBaseLine from "./../components/HOME/Banner/BannerBaseLine";

export async function getStaticProps(){

console.log(data)

From https://nextjs.org/docs/basic-features/data-fetching#getstaticprops-static-generation
Note: You should not use fetch() to call an API route in
getStaticProps. Instead, directly import the logic used inside your
API route. You may need to slightly refactor your code for this
approach.
Fetching from an external API is fine!
you should check if categories exist
export default function HomeMain({categories}) {
if(categories){
return <Loading Component />
}
rest of the code...

In this code i am passing both imageurl and size which are javascript variables but i am using in css.
css is not considering both. How to resolve this issue ??
const MenuItem = ({title, imageUrl, size}) => {
return(
<div className="${size} menu-item">
<div className="background-image" style={{backgroundImage: "url(${imageUrl})"}} />
<div className="content">
<h1 className="title">{title.toUpperCase()}</h1>
<span className="subtitle">SHOP NOW</span>
</div>
</div>
);
}
This should work:
const MenuItem = ({title, imageUrl, size}) => {
return(
<div className={`${size} menu-item`}>
<div className="background-image" style={{backgroundImage: "url(${imageUrl})"}} />
<div className="content">
<h1 className="title">{title.toUpperCase()}</h1>
<span className="subtitle">SHOP NOW</span>
</div>
</div>
);
}
To use variables inside a string like this, you need to use the following syntax:
className={`${size} menu-item`}
You should wrap them in back-ticks (``):
const MenuItem = ({title, imageUrl, size}) => {
return(
<div className=`${size} menu-item`>
<div className="background-image" style={{backgroundImage: `${url(${imageUrl})}`}} />
<div className="content">
<h1 className="title">{title.toUpperCase()}</h1>
<span className="subtitle">SHOP NOW</span>
</div>
</div>
);
}
I am new to React and recently started working on it. I know that we cannot change the components properties using the props.
I want to know how can we change the properties of Component?
Below is my code:
Courses.jsx
function Courses(){
return (
<div className="courses">
<h1>Ongoing Courses</h1>
<div className="row">
{CourseData.map((value,index)=>{
return (
<div className="col-md-3">
<Card title={value.title} completed={value.completed} content={value.content} value="Resume !" key={index} id={index} />
</div>
);
})}
</div>
</div>
);
}
Here above i am having a Array of Data named as courseData, I am mapping it on a Card component.
Card.jsx:
function Card(props){
function handleClick(){
}
return (
<div className="card">
<div className="card-body">
<h2 className="card-title">{props.title}</h2>
{props.content}
<br/>
<button className="btn btn-danger" > {props.value}</button>
</div>
</div>
);
}
the CourseData has following properties :
courseData : [{
key,
title,
completed
content}]
I simply want that when ever the button present is card gets clicked then the completed attribute of courseData changed to some different value that is passed through the props .
I have tried a lot but not able to do .
Any help regarding this will be helpful for me .
courseData.jsx:
const notes = [{
key: 1,
title: "some Text",
completed:false,
content: "some Text"
},
{
key: 2,
title: "some Text",
completed:false,
content: "some Text"
}]
export default notes;
Add CourseData to the state of the Courses component. Then add a method to adjust the data there. Pass the method throught props that will be called when clicking button in the Card component:
function Courses() {
const [courseData, setCourseData] = useState(CourseData);
const updateCourseData = (index) => {
courseData.splice(index, 1);
setCourseData(courseData);
}
return (
<div className="courses">
<h1>Ongoing Courses</h1>
<div className="row">
{courseData.map((value,index)=>{
return (
<div className="col-md-3">
<Card title={value.title} updateCourseData={updateCourseData} completed={value.completed} content={value.content} value="Resume !" key={index} id={index} />
</div>
);
})}
</div>
</div>
);
}
in the Card.jsx:
<button onClick={() => props.updateCourseData(props.id)} className="btn btn-danger" > {props.value}</button>
function Courses(){
const [coursesData, setCoursesData] = useState(CourseData)
return (
<div className="courses">
<h1>Ongoing Courses</h1>
<div className="row">
{coursesData.map((value,index)=>{
return (
<div className="col-md-3">
<Card coursesData={coursesData} setCoursesData={setCoursesData} title={value.title} completed={value.completed} content={value.content} value="Resume !" key={index} id={index} />
</div>
);
})}
</div>
</div>
);
function Card({id,title,value,content,coursesData,setCoursesData }){
function handleClick(e){
e.preventDefault()
setCoursesData(coursesData => {
const data = coursesData
data.splice(id,1,{
title: title,
completed: value,
content: content,
key: id
})
return data
})
}
return (
<div className="card">
<div className="card-body">
<h2 className="card-title">{title}</h2>
{content}
<br/>
<button onClick={handleClick} className="btn btn-danger">{value}</button>
</div>
</div>
);
