Get All Elements By ClassName and Change ClassName

Question

I would like to...

1. Scan the document for all elements that have a certain class name
2. Perform some key functions on the innerHTML of that element

Answer 1

Another approach could be to use a selector:

var arr = document.querySelectorAll('.exampleClass');
for (var i=0;i

Although it's not compatible with older browsers, it can do the trick as well if the webcontent is for modern browsers.
