In this article, we will be explaining to you how to create an editable div using HTML, CSS, and JavaScript. An editable div is one on which is you will click then it will generate an editable text area to edit or to write any text on your browser itself. After editing, when you click on somewhere else on your browser then that text will be displayed as a constant text (without editable).
Prerequisites: You should be familiar with the basics of HTML, CSS, and JavaScript.
Creating structure: Create two files for HTML, and JavaScript. To create these files run the following command
-
Syntax:
$ touch index.html app.js
-
Step 1: Edit index.html. This file contains the following Code.
HTML
<!DOCTYPE html><htmllang="en"><body><h1style="color: green;text-align: center;">Creating Editable Div GeeksforGeeks</h1><divstyle="text-align: center;margin-left: 35%;"class="container"><divid="first"></div></div></body><scriptsrc="app.js"></script></html> -
Step 2: Edit the app.js file. This file contains the following Code.
Javascript
// Creating a new elementlet editableDiv = document.createElement('div');// Adding text to that created elementlet value = localStorage.getItem('text');let text;if(value ==null){text = document.createTextNode('Click on it to edit this Editable Div');}else{text = document.createTextNode(value);}editableDiv.appendChild(text);editableDiv.setAttribute('id','elem');editableDiv.setAttribute('class','elem');editableDiv.setAttribute('style','font-size:3rem;border:3px solid;width:350px;height:200px;');// Access the main containerlet container = document.querySelector('.container');// Inserting the element with id = firstcontainer.insertBefore(editableDiv, first);// Adding event listener to the divElemeditableDiv.addEventListener('click',function(){let lengthOfTextAreas =document.getElementsByClassName('textarea').length;if(lengthOfTextAreas == 0){let html = elem.innerHTML;editableDiv.innerHTML =`<textarea class="textarea form-control"id="textarea"rows="3">${html}</textarea>`;}// Listening the blur event on textarealet textarea = document.getElementById('textarea');textarea.addEventListener('blur',function() {elem.innerHTML = textarea.value;localStorage.setItem('text', textarea.value);})});
Final Solution: This is the combination of the above two steps.
HTML
<!DOCTYPE html> <html lang="en">
<body>
<h1 style="color: green;
text-align: center;">
Creating Editable Div GeeksforGeeks
</h1>
<div style="text-align: center;
margin-left: 35%;"
class="container">
<div id="first"></div>
</div>
</body>
<script>
// Creating a new element
let editableDiv = document.createElement('div');
// Adding text to that created element
let value = localStorage.getItem('text');
let text;
if (value == null){
text = document.createTextNode
('Click on it to edit this Editable Div');
}
else{
text = document.createTextNode(value);
}
editableDiv.appendChild(text);
editableDiv.setAttribute('id', 'elem');
editableDiv.setAttribute('class', 'elem');
editableDiv.setAttribute('style',
'font-size:3rem;border:3px solid;
width:350px;height:200px;');
// Access the main container
let container = document.querySelector('.container');
// Inserting the element with id = first
container.insertBefore(editableDiv, first);
// Adding event listener to the divElem
editableDiv.addEventListener('click',function (){
let lengthOfTextAreas =
document.getElementsByClassName('textarea').length;
if(lengthOfTextAreas == 0){
let html = elem.innerHTML;
editableDiv.innerHTML =
`<textarea class="textarea form-control" id="textarea" rows="3">
${html}</textarea>`;
}
// Listening the blur event on textarea
let textarea = document.getElementById('textarea');
textarea.addEventListener('blur',function() {
elem.innerHTML = textarea.value;
localStorage.setItem(
'text', textarea.value);
})
});
</script>
</html>

Output: When you will open it on any browser then the following output would be generated.
