How to create element in javascript?
In JavaScript, you can create an element using the document.createElement() method. Here’s an example:
// create a new paragraph element const paragraph = document.createElement('p'); // set the inner text of the paragraph paragraph.innerText = 'This is a new paragraph created with JavaScript!'; // add the paragraph to the body of the page document.body.appendChild(paragraph);
In this example, we first create a new p element using document.createElement(‘p’). We then set the text of the paragraph using the innerText property. Finally, we add the paragraph to the body of the page using the appendChild() method.
You can also add attributes to the element using the setAttribute() method:
// create a new image element const image = document.createElement('img'); // set the src attribute of the image image.setAttribute('src', 'https://example.com/image.jpg'); // add the image to the body of the page document.body.appendChild(image);
In this example, we create a new img element and set its src attribute using the setAttribute() method. We then add the image to the body of the page using the appendChild() method.
