javascript (prototype) if element does not have attribute

Question

in prototype I have this 'if' statement that works fine:

if(parentForm.hasAttribute('action')){
 console.log('hello world')
}

However, how do I turn this into a 'if parentForm DOES NOT have attribute action' statement?

Many thanks, Adi.

Simply negate the conditional using the logical not operator;

if(!parentForm.hasAttribute('action')){
 console.log('hello world')
}
