Adding attributes to an element using JavaScript

Question

Is it possible to add an attribute to an element using JavaScript? If it is possible, how do I do it?

Answer 1

yes, for example you want to change the height attribute of an image..simply.. :

document.getElementById("img_id").setAttribute("height","50px");

Answer 2

so if I want to add 2 attributes, I just need to add the .setAttribute twice?

Answer 3

You may try this...
var img= document.getElementById("img_id");

img.setAttribute("height","50px");
img.setAttribute("width","50px");

Answer 4

Yes
Or
You could also use a jquery command
$('#elementId').attr('attributename','newvalue');

You just have to add a different attributename for every attribute you wanna change
