JS Get document Element

We usually manipulate an HTML element, so how do we get the HTML element? There are usually a few methods:

1. Select elements by ID

var element=document.getelementbyid ("Idname");

2. Select by name

var radios=document.getelementsbyname ("Favacolor");

3. Get elements by tag name

var menu = document.getElementById ("menu"); var element = Menu.getelementsbytagname ("h3");

4. Select by CSS Class

var elements=document.getelementsbyclassname ("ClassName");

5. Select by CSS Selector

Using the Queryselectorall () or Queryselector () method

var radios=document.queryselectorall ('. Favacolor ');
