DOM Creating content

Create Content

You can create a div element an set the content.

We use the document method createElement and the DOM node method appendChild

let e = document.createElement('div');
e.innerHTML = 'Hello';
document.body.appendChild(e);

let e = document.createElement('div');
e.innerHTML = 'Hello world';
document.body.appendChild(e);

Create img

You can create a img element an set the src. In this example you must set the src and the style of the new element a.

a.style = 'width:100px;border:solid;';

These are CSS properties.

let a = document.createElement('img');
a.src = '/flags/fr.png';
document.body.appendChild(a);

let a = document.createElement('img');
a.src = '/flags/fr.png';
a.style = 'width:100px;border:solid;';
document.body.appendChild(a);

Create multiple elements

• You can add several elements to the document.body.
• You can add elements to other elements.
• Change this code to match the model answer
• Can you see why the flag does not show?

let a = document.createElement('div');
a.innerHTML = 'France, ';
let b = document.createElement('i');
b.innerHTML = 'Paris';
a.appendChild(b);
document.body.appendChild(a);
let c = document.createElement('img');
c.src = '/flags/fr.png';
c.style = 'width:100px';

let a = document.createElement('div');
a.innerHTML = 'Germany, ';
let b = document.createElement('i');
b.innerHTML = 'Berlin';
a.appendChild(b);
document.body.appendChild(a);
let c = document.createElement('img');
c.src = '/flags/de.png';
c.style = 'width:100px';
document.body.appendChild(c);

Setting complex innerHTML

You can put more complex HTML into an element. The backticks ` ` can span many lines.

let a = document.createElement('div');
a.innerHTML = `
  <img src='/flags/gr.png' style='height:1ex'>
  Greece <i>Athens</i>`;
document.body.appendChild(a);
let b = document.createElement('div');
b.innerHTML = `
  <img src='/flags/it.png' style='height:1ex'>
  Italy <i>Rome</i>`;
document.body.appendChild(b);

let a = document.createElement('div');
a.innerHTML = 'Germany, ';
let b = document.createElement('i');
b.innerHTML = 'Berlin';
a.appendChild(b);
document.body.appendChild(a);
let c = document.createElement('img');
c.src = '/flags/de.png';
c.style = 'width:100px';
document.body.appendChild(c);
