Add hasOption method to NodeElement class. #766
Conversation

This will trigger 2 changes of the data of the form, to check whether it has an option or no. that's quite bad as implementation of the check. |

Yeah you are right with this. I will rewrite it to don't change the value of the select. |

this is wrong. It must return a boolean

I writed this because if the element is not a select tag, It is not logical to return a boolean. That would be nice if I throw an exception instead of return null? Or editing the documentation of method to @return Boolean|null?

IMO it's better to throw an exception.

You can safely inline this variable, because it's used only once.
In my case that was a useful method, to check that a select element has an option or not. And I think this will be also useful for others.
