First of all Greeting from my side I am beginner in Reactjs and I am learning a new hook called useRef() hook. Basically I am trying to fetch the content of every element present in my div using useRef Hook. In my code I need to access the content of only p tag how can I achieve it? This is my Code:-
import React,{useRef} from 'react'
function FormData() {
const getAllData = useRef(null)
const onClickHandler = () =>{
console.log(getAllData.current)
}
return (
<div ref={getAllData} >
<h1>UseRef Tutorial</h1>
<p>Abhishek Poddar</p>
<input type="email" placeholder='Enter the Email' />
<br></br>
<br></br>
<input type="password" placeholder='Enter the Password' />
<br></br>
<br></br>
<button onClick={onClickHandler}>Click Me</button>
</div>
)
}
export default FormData
Ok so if you just need to access the P tag. then you can modify your OnlickHandler something like this.
const onClickHandler = () => {
console.log(getAllData.current.children[1].innerText);
};
you can access the current elements' child properties by going through its indexes. So in that case your P tag lies on the 1st index so you can just do and you'll get the P tag.
.children[index]
getAllData.current
now is an element object
. list of properties and methods
you can access its children via children
property.
const onClickHandler = () => {
const list = getAllData.current.children;
for (const e of list) {
if (e.tagName === "P") {
console.log(e.textContent);
}
}
};
