TypeError: 'click' called on an object that does not implement interface HTMLElement

Question

I have some javascript that sends data to a function that calls a php page, however I get an error that I can\'t find any information on. The postData() call is in the middl

Answer 1

In my case was the same problem like @user3740976. I put in url an undefined parameter.

$.ajax({
     type: requestType,
     url: url,       
     dataType: dataType,
     data: dataParams,
 ...

Where dataParams is

 {"title":{},"iSBN":"111","partNumber":"3332","bookCategory":"1"}

title being undefined.
