Good day!

When I insert the tag <object data="data.svg" type="image/svg+xml"></object> or <embed src="data.svg" type="image/svg+xml" /> is written to the console error: "Uncaught TypeError: Can not read property 'length' of undefined", file ad.js and line 53.

In this line of code: if ( str.length === 0 ) {
Maybe it makes sense replace to: if ( !str || str.length === 0 ) {
  
====== Do not touch below this line ======
