remove empty tag

[mrbbp]

Hello sure my question is stupid but i do not understand your example:

sanitizeHtml(
  '<p>This is <a href="http://www.linux.org"></a><br/>Linux</p>',
  {
    exclusiveFilter: function(frame) {
      return frame.tag === 'a' && !frame.text.trim();
    }
  }
);

i'm trying to remove empty span and p or fill with or whitespace

i do not understand this line return frame.tag === 'a' && !frame.text.trim(); i do not understand the return with the test inside... (sorry it's tricky for me) what does it suppose to return if tag is a and ???

would you kindly develop your line?

best regards

This line returns true if the tag is "a" and it contains no text (frame.text.trim() is falsy, i.e. the empty string).

So it discards links with no text in them and keeps the rest.

JavaScript treats expressions the same way regardless of whether they are part of a "return" statement, an "if" statement, an assignment, etc.
